janine spends 1 tenths hour making the bed 1 fiths hour getting dressed and 1 half hour eating breakfast what fraction of an hour does she spend doing these activitys
Therefore, Janine spends 4/5 of an hour doing these activities.
To determine the fraction of an hour that Janine spends doing the given activities, we need to convert the given times to fractions of an hour. We know that 1 hour is equivalent to 1 whole, which means that half an hour would be equivalent to half of a whole.
Similarly, one-fifth of an hour would be equivalent to 1 ÷ 5, which is 0.2, and one-tenth of an hour would be equivalent to 1 ÷ 10, which is 0.1.
Now, let's add the three times together to find the total time:
1/10 hour making the bed + 1/5 hour getting dressed + 1/2 hour eating breakfast = 1/10 + 2/10 + 5/10= 8/10 (which can be simplified to 4/5).

A brand of cereal had 1. 21. 21, point, 2 milligrams (\text{mg})(mg)left parenthesis, start text, m, g, end text, right parenthesis of iron per serving. Then they changed their recipe so they had 1. 8\,\text{mg}1. 8mg1, point, 8, start text, m, g, end text of iron per serving. What was the percent increase in iron?.
The percent increase in iron content after the recipe change for the cereal is approximately 35.56%.
To calculate the percent increase in iron content, we need to find the difference between the new iron content (1.8 mg) and the original iron content (1.21 mg). The difference is 1.8 - 1.21 = 0.59 mg. Then, we divide this difference by the original iron content (1.21 mg) and multiply by 100 to get the percentage increase: (0.59 / 1.21) × 100 ≈ 35.56%.
This means that the iron content of the cereal increased by approximately 35.56% after the recipe change. To calculate the percent increase, we compare the difference between the new and original values to the original value. In this case, the original iron content was 1.21 mg, and the new iron content is 1.8 mg. The difference between these two values is 1.8 - 1.21 = 0.59 mg. To find the percentage increase, we divide this difference (0.59 mg) by the original value (1.21 mg) and multiply by 100.
The resulting value, 0.59 / 1.21 ≈ 0.4876, represents the proportion of increase. Multiplying it by 100 gives us the percentage increase, which is approximately 48.76%. Therefore, the iron content increased by approximately 48.76% after the recipe change.

Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing is equivalent to 1. 5 feet on the actual banner, what will the area of the actual banner be?.
The area is then calculated as (1/2) * base * height, resulting in approximately 39.375 square feet.
To find the area of the actual banner, we need to scale up the dimensions from the drawing to real-world measurements. We are given that 1 inch on the drawing is equivalent to 1.5 feet on the actual banner.
The base of the triangle on the drawing is 5 inches, so the base of the actual triangle will be:
5 inches * 1.5 feet/inch = 7.5 feet
Similarly, the height of the actual triangle will be:
7 inches * 1.5 feet/inch = 10.5 feet
Now that we have the base and height of the actual triangle, we can calculate its area using the formula for the area of a triangle:
Area = (1/2) * base * height
Area = (1/2) * 7.5 feet * 10.5 feet
Area ≈ 39.375 square feet
Therefore, the area of the actual banner will be approximately 39.375 square feet.

How to determine value of the variables for ABCD?In order for any quadrilateral to be considered as a parallelogram, two pairs of its parallel sides must be equal (congruent). This ultimately implies that, the diagonals of a parallelogram would bisect one another only when their midpoints are the same:
Line segment AC = Line segment BD
Next, we would write an equation to model the length of the diagonals of this parallelogram as follows;
4x - 2 = 3y - 1 .........equation 1.
3y - 3 = 3x .........equation 2.
From equation 2, we have the following:
y - 1 = x .........equation 3.
By substituting equation 3 into equation 1, we have:
4(y - 1) - 2 = 3y - 1
4y - 4 - 2 = 3y - 1

Julia writes 2 fractions with the same denominator that have numerators 8 and 2 . What could the denomination be if the sum is less than 1.?Equal to 1? Greater than 1?
If the sum of the fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.
To find a denominator that satisfies the given conditions, we can consider the fractions with numerators 8 and 2. If the sum of these fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.
To determine the possible denominators that satisfy the conditions, we need to consider the given numerators of 8 and 2. Since the fractions have the same denominator, let's denote it as 'd'. The fractions can be written as 8/d and 2/d.
If the sum of these fractions is less than 1, we have:
8/d + 2/d < 1
Combining the fractions, we get:
(8 + 2)/d < 1
Simplifying, we have:
10/d < 1
To satisfy this inequality, the denominator 'd' can be any number greater than 10. For example, if we choose d = 11, the fractions become 8/11 and 2/11, and their sum is 10/11, which is less than 1.
If the sum of the fractions is equal to 1, we have:
8/d + 2/d = 1
Combining the fractions, we get:
10/d = 1
Solving for 'd', we find that the denominator must be 10. For example, if we choose d = 10, the fractions become 8/10 and 2/10, and their sum is 10/10, which is equal to 1.
If the sum of the fractions is greater than 1, we have:
8/d + 2/d > 1
Combining the fractions, we get:
10/d > 1
To satisfy this inequality, the denominator 'd' must be less than 10. For example, if we choose d = 9, the fractions become 8/9 and 2/9, and their sum is 10/9, which is greater than 1.
In summary, if the sum of the fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.

Based on Amadou's measurements, the height of the skyscraper is approximately 97.2 meters.
Amadou measures the angle of elevation from his eye to the top of the skyscraper as 44 degrees. To determine the height of the skyscraper, we can use trigonometry. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side.
In this case, the opposite side represents the height of the skyscraper, and the adjacent side represents the horizontal distance from Amadou to the base of the skyscraper. We are given that the adjacent side is 164 meters and the angle of elevation is 44 degrees.
Using the tangent function, we can set up the following equation:
tan(44 degrees) = height of skyscraper / 164 meters
To solve for the height of the skyscraper, we rearrange the equation:
height of skyscraper = tan(44 degrees) * 164 meters
Using a scientific calculator or trigonometric table, we find that tan(44 degrees) is approximately 0.9659. Multiplying this value by 164 meters gives us the height of the skyscraper:
height of skyscraper ≈ 0.9659 * 164 meters ≈ 97.2 meters
Therefore, based on Amadou's measurements, the height of the skyscraper is approximately 97.2 meters.

Gunther's starting weight is 248 pounds, and he plans to lose 2 pounds each week. Use a linear equation to determine Gunther's weight after 10 weeks. Do not include units in your answer
To determine Gunther's weight after 10 weeks, we can use a linear equation. Given that he plans to lose 2 pounds each week, we can represent his weight after 10 weeks as a linear function of time. Therefore, Gunther's weight after 10 weeks would be 268 pounds.
1. The equation would be: weight = starting weight - (rate of weight loss * number of weeks). Substituting the given values, we find Gunther's weight after 10 weeks.
2. Gunther's weight after 10 weeks can be determined using a linear equation. Let's denote Gunther's starting weight as W₀ and the rate of weight loss as R. Since he plans to lose 2 pounds each week, the rate of weight loss R is -2 (negative because it represents a decrease in weight).
3. The equation for Gunther's weight after 10 weeks would be: weight = W₀ - (R * number of weeks).
Substituting the given values, we have weight = 248 - (-2 * 10).
4. Simplifying further, weight = 248 + 20 = 268. Therefore, Gunther's weight after 10 weeks would be 268 pounds.

Suppose that the function f(x) = 5.32 + 0.80x represents the cost of mailing an object that weighs x pounds. What is f(36)?
The value of function at x = 36 is 34.12.
To find the cost of mailing an object that weighs 36 pounds, we can substitute the value of x into the function f(x) = 5.32 + 0.80x.
The function f(x) = 5.32 + 0.80x represents a linear relationship between the weight of the object (x) and the cost (f(x)) with a base cost of $5.32 and an additional cost of $0.80 per pound. By plugging in the value of 36 into the function, we can calculate the specific cost for that weight.
Plugging in x = 36, we have:
f(36) = 5.32 + 0.80 * 36
Simplifying the expression:
f(36) = 5.32 + 28.8
f(36) = 34.12
Therefore, f(36) is equal to 34.12. This means that it would cost $34.12 to mail an object weighing 36 pounds according to the given function.

To calculate Stephanie Ambrose's annual base premium, we need to sum up the costs of her bodily injury, property damage, comprehensive, and collision insurance.
Given that the bodily injury limits are $100/300 and the property damage limits are $100,000, we can calculate the cost of bodily injury and property damage insurance. The cost for bodily injury insurance is $100 for every $100,000 of coverage, and the cost for property damage insurance is $100 for every $100,000 of coverage.
For bodily injury insurance, the cost is calculated as:
(100/300) * 100 = $33.33
For property damage insurance, the cost is:
(100,000/100,000) * 100 = $100
Adding up the costs of bodily injury, property damage, comprehensive, and collision insurance:
Base premium: $292.50
Comprehensive insurance: $75.90
Collision insurance: $225.79
Bodily injury insurance: $33.33
Property damage insurance: $100
Total annual base premium = Base premium + Comprehensive insurance + Collision insurance + Bodily injury insurance + Property damage insurance
Total annual base premium = $292.50 + $75.90 + $225.79 + $33.33 + $100 = $727.52

The given equation is I = -2OD where I is the intensity of light, O is the aperture of the lens and D is the distance between the lens and the object. This equation is known as the Inverse Square Law of Light.
The equation states that the intensity of light decreases as the square of the distance between the object and the ens increases. This means that if we double the distance between the object and the lens, the intensity of light becomes 1/4th of its original value.Similarly, if we triple the distance between the object and the lens, the intensity of light becomes 1/9th of its original value. This law is applicable to all types of light sources, including natural light sources like the sun and artificial light sources like bulbs.One practical application of this law is in photography. If a photographer wants to capture an image of a subject that is far away, they need to use a lens with a larger aperture to let in more light. This will ensure that the image is bright and clear even when the distance between the subject and the camera is large.Similarly, if a photographer wants to capture an image of a subject that is close to the camera, they need to use a lens with a smaller aperture to reduce the amount of light that enters the camera. This will prevent the image from being overexposed and washed out.Overall, the Inverse Square Law of Light is an important principle that governs the behavior of light in various applications, including photography, cinematography, and physics.For such more question on Square Law

On Monday, 238 students and 10 teachers went on a trip to the zoo. If a bus can hold 58 people each, how many busses are needed? (Hint: remember you cannot have part of a bus and you must have enough to fit all people
we would need a total of 5 buses to accommodate all the students and teachers on the trip.To determine the number of buses needed, we divide the total number of students and teachers by the capacity of each bus, which is 58 people.
238 students + 10 teachers = 248 people
To calculate the number of buses needed, we divide 248 people by 58 people per bus:
248 people ÷ 58 people/bus ≈ 4.276 buses
Since we cannot have a fraction of a bus, we round up to the nearest whole number. Therefore, we would need a total of 5 buses to accommodate all the students and teachers on the trip.
It's important to note that rounding up ensures that there are enough buses to accommodate all the individuals, even if there are some empty seats on each bus.

Once the check has cleared, Alli has $17.55 in her savings account. Finally, the amount of money Alli has in her savings account after the check has cleared is $25, so the answer is option A: $17.55.
Initial amount in Alli's checking account = $382.45
Initial amount in Alli's savings account = $450
Amount Alli withdrew from checking account = $400
Amount the bank withdrew from Alli's savings account = $25
Total cost of the check = 400+25
=425
Since the initial amount in her checking account was insufficient, the bank automatically withdrew $25 from her savings account to cover the cost of the check. This means that Alli has a total of $425 - $400 = $25 left in her savings account.After the withdrawal from her savings account, Alli's remaining savings balance is $450 - $25 = $425. However, she spent $400 to cover the check, so her final savings balance is $425 - $400 = $25.

A cone with equal height and radius has volume 1234 cm³. To find the height of the cone, we will use the formula for the volume of a cone: V = 1/3πr²h
where: V is the volume of the cone, π is pi (3.14), r is the radius of the cone, h is the height of the cone
We are given that the height and radius of the cone are equal, so we can substitute r for h. Also, we know the volume of the cone is 1234 cm³. So:
1234 = 1/3πr²h
1234 = 1/3πr²(r)
1234 = 1/3πr³ (since r = h)
Now we can solve for r: 1234 * 3 / π = r³
3747.22 = r³
r ≈ 14.98 cm
Since the height is equal to the radius, the height of the cone to the nearest tenth of a centimetre is 14.98 cm.

It is 185 miles to Fort Worth if vangs drives 2 hours at 65 miles per hour how far will he be from Fort Worth
If Vangs drives for 2 hours at a speed of 65 miles per hour, we can calculate how far he will be from Fort Worth. Vangs will be 125 miles away from Fort Worth.
Given that Vangs drives at a speed of 65 miles per hour for 2 hours, we can calculate the distance traveled using the formula Distance = Speed × Time.
Distance = 65 miles/hour × 2 hours = 130 miles.
Since Vangs started 185 miles away from Fort Worth and traveled a distance of 130 miles, we subtract the distance traveled from the initial distance to find how far he will be from Fort Worth.
Distance from Fort Worth = Initial distance - Distance traveled = 185 miles - 130 miles = 55 miles.

A basketball team has won 70% of the 20 games they have played. If they win all their remaining games, how many would they have to play to increase their win percentage to 80%. Please explain your answer and show your reasoning.
To increase their win percentage from 70% to 80%, the basketball team needs to win a specific number of remaining games.
Let's first determine the number of games the team has won out of the 20 games played. Since they have won 70% of the games, we can calculate that as 0.7 * 20 = 14 games won.
Now, let's assume the team has to play 'x' remaining games to achieve an 80% win percentage. If they win all the remaining games, they will have a total of 20 + x games played and 14 + x games won.
To find the win percentage, we divide the total number of games won by the total number of games played and set it equal to 80% or 0.8:
(14 + x) / (20 + x) = 0.8
We can solve this equation to determine the value of 'x':
0.8 * (20 + x) = 14 + x
16 + 0.8x = 14 + x
0.8x - x = 14 - 16
0.2x = -2
x = -2 / 0.2
x = -10
Since we cannot have a negative number of remaining games, it is not possible for the team to increase their win percentage to 80% by winning all their remaining games.

Let's represent the amount of money Justin has as [tex]\(x\).[/tex]
According to the given information, Trey has 3 times what Justin has, so Trey has [tex]\(3x\)[/tex] dollars.
Leila has 10 dollars more than Justin, so she has [tex]\(x + 10\)[/tex] dollars.
The sum of the amounts of money they have is 125 dollars:
[tex]\(x + 3x + (x + 10) = 125\)[/tex]
Combining like terms, we have:
[tex]\(5x + 10 = 125\)[/tex]
Subtracting 10 from both sides:
[tex]\(5x = 115\)[/tex]
Dividing both sides by 5:
[tex]\(x = 23\)[/tex]
So Justin has 23 dollars.
Trey has 3 times that amount:
[tex]\(3 \times 23 = 69\)[/tex]
Leila has 10 dollars more than Justin:
[tex]\(23 + 10 = 33\)[/tex]
