In two triangles the ratio of their area is 4:3 and that of their height is 3:4. Find the ratio of their bases?
The ratio of their bases is 2:3.
Let's assume the bases of the two triangles are b1 and b2, and their heights are h1 and h2, respectively.
We know that the ratio of their areas is given as 4:3. This implies (1/2) * b1 * h1 : (1/2) * b2 * h2 = 4:3. Simplifying this equation, we get b1 * h1 : b2 * h2 = 4:3.
Given that the ratio of their heights is 3:4, we have h1 : h2 = 3:4.
Using these two ratios, we can find the ratio of their bases by substituting the values. We have (b1 * 3) : (b2 * 4) = 4:3.
Cross-multiplying, we get 3b1 = 4b2, which simplifies to b1 : b2 = 4:3.
Therefore, the ratio of their bases is 4:3.

The west tower and east tower are 15 miles away from each other. A fire is 41 degrees north of east and 56 degrees north of west to form a triangle with the fire. A forest ranger in the west observation tower spots a fire 41° north of east. Fifteen miles directly east, the forest ranger in the east tower spots the same fire at 56° north of west. How far away is the ranger who is closest to the fire? Approximate the distance by rounding to the nearest hundredth of a mile. 9. 91 mi 11. 87 mi 12. 53 mi 18. 95 mi.
The ranger who is closest to the fire is approximately 9.91 miles away.
Given that the west tower and east tower are 15 miles away from each other, and the fire is observed at angles of 41 degrees north of east and 56 degrees north of west, we can use trigonometry to determine the distances of the rangers from the fire.
Let's denote the distance from the west tower to the fire as x and the distance from the east tower to the fire as y. Using the tangent function, we can set up the following equations:
In the west tower triangle:
tan(41°) = x / 15
In the east tower triangle:
tan(56°) = y / 15
Solving these equations, we find:
x = 15 * tan(41°) ≈ 9.91 miles (rounded to the nearest hundredth)
y = 15 * tan(56°) ≈ 18.95 miles (rounded to the nearest hundredth)
Comparing the distances, we can conclude that the ranger in the west tower is closer to the fire, with a distance of approximately 9.91 miles.

The number of people who like a particular video online triples every day after the day the video is posted and 15 people like the video on the day it is posted.
We need to find an inequality which can be used to find the number of days, t, it takes for the number of people who have liked the video to reach more than 3000. The inequality which can be used to find the number of days, t, it takes for the number of people who have liked the video to reach more than 3000 is: 15 + 3t > 3000
The above inequality is correct because the number of people who like a particular video online triples every day after the day the video is posted. This means that on the 2nd day, 3 * 15 people like the video. On the third day, 3 * 3 * 15 people like the video, which is equal to 9 * 15 people.
Therefore, the total number of people who like the video on the 1st, 2nd and 3rd day is:
15 + 3 * 15 + 9 * 15 = 15 + 45 + 135 = 195
We can see that the number of people who like the video on the 1st day itself is only 15, which is very less. We need to get the number of people who have liked the video to reach more than 3000. Therefore, the above inequality is used.

straight back south 20 meters. What distance did she travel?
12
Skylar travels 50 meters N and then goes 30 meters West before coming straight back south 20 meters. She travelled approximately 36.06 meters.
Skylar's travels are as follows:
She travels 50 meters N and then goes 30 meters West before coming straight back south 20 meters.
To figure out the distance she covered, use the Pythagorean theorem.
Consider the horizontal and vertical distances covered. By the Pythagorean theorem, we can obtain the diagonal distance.
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (c) equals the sum of the squares of the other two sides (a and b).So, a² + b² = c²
Where, a is the length of one of the legs (horizontal distance).
b is the length of the other leg (vertical distance).
c is the length of the hypotenuse (diagonal distance).
So, a = 30 meters (Westward),b = 20 meters (Southward),c = diagonal distance.
To find c, we can use the Pythagorean theorem:
c² = a² + b²
c² = (30)² + (20)²
c² = 900 + 400
c² = 1300
Take the square root of both sides to obtain c:
c = √1300c ≈ 36.06 meters

Which type of tax describes excise taxes, sales taxes, and tolls?
All three types of taxes fall under the category of indirect taxes because they are not directly based on an individual's income or wealth but rather on the consumption of goods, services,
or use of specific infrastructure.The types of taxes you mentioned, namely excise taxes, sales taxes, and tolls, are all examples of indirect taxes. Indirect taxes are imposed on goods, services, or transactions rather than directly on individuals or entities.
They are typically collected by intermediaries, such as businesses or service providers, who then pass on the tax burden to the consumers.
Excise taxes are levied on specific goods, such as alcohol, tobacco, gasoline, or luxury items. They are often intended to discourage the consumption of these goods or to generate revenue for the government.
Sales taxes are imposed on the sale of goods and services and are usually calculated as a percentage of the purchase price. They are collected by the seller from the buyer at the point of sale.
Tolls, on the other hand, are charges imposed on the use of certain infrastructure, such as roads, bridges, tunnels, or highways.

Looking at the entries in columns A and B, we can see that Y corresponds to the second row in both columns. The values in column A (X, Y, Z, 1.0) represent different categories or levels of a variable, while the values in column B (0.25, 0.68, 0.07, 1.0) represent corresponding measurements or values associated with each category.
To assess the association between variables, we need to consider if the values in column B change systematically or show a pattern based on the different categories in column A. If there is a clear pattern or trend, it indicates a stronger association between the variables.
Now, let's compare the values for Y in column B: 0.25, 0.68, 0.07, and 1.0.
Of these values, the one that is least likely to indicate an association between the variables would be 0.07.
The reason is that the other values (0.25, 0.68, and 1.0) are relatively closer to each other and show a more consistent pattern. The value 0.07 stands out as an outlier compared to the other values, suggesting a weaker association or potentially unrelated measurement for the corresponding category in column A.
In summary, among the options provided, the value for Y in the table that would be least likely to indicate an association between the variables is 0.07.

The volume of a cube is 1.5m^3. Find the length of its edge to the nearest tenth of a meter
The length of the edge of the cube with a volume of 1.5m^3, rounded to the nearest tenth of a meter, is approximately 1.4 meters.
To find the length of the edge of the cube, we can use the formula for the volume of a cube, which is given by V = s^3, where V is the volume and s is the length of the edge. In this case, we are given that the volume is 1.5m^3. Rearranging the formula, we have s = V^(1/3). Substituting the given volume, we get s = 1.5^(1/3). Evaluating this expression, we find that s is approximately 1.4 meters. Rounding this value to the nearest tenth of a meter, we conclude that the length of the edge of the cube is approximately 1.4 meters.

The cost of all your ingredients for your cake is $3. 49. You consistently sell 150 cakes per week for $976 in total sales. What is your food cost percentage?
The cost of ingredients for a cake is $3.49, and the total weekly sales from selling 150 cakes are $976. We will calculate the food cost percentage. The food cost percentage is approximately 35.76%.
To calculate the food cost percentage, we need to determine the portion of the total sales that goes towards the cost of ingredients. The food cost is the cost of ingredients, and the total sales is the revenue generated.
First, we calculate the cost per cake:
Cost per cake = Cost of ingredients / Number of cakes sold
Cost per cake = $3.49 / 150 cakes
Cost per cake ≈ $0.0233
Next, we calculate the total cost of ingredients for all the cakes sold:
Total cost of ingredients = Cost per cake * Number of cakes sold
Total cost of ingredients = $0.0233 * 150 cakes
Total cost of ingredients = $3.495
Now, we can calculate the food cost percentage:
Food cost percentage = (Total cost of ingredients / Total sales) * 100
Food cost percentage = ($3.495 / $976) * 100
Food cost percentage ≈ 0.3576 * 100
Food cost percentage ≈ 35.76%
Therefore, the food cost percentage is approximately 35.76%.

Levi is a plumber, and his coworker Tom is an electrician. Levi charges customers a fee of $60 just to come to their houses and then $1 per minute that he is there. Tom also charges a fee of $40 for a home visit, plus an additional $3 per minute. Last week the coworkers went to a job site together, spent the same amount of time working, and earned the same amount. How much did each one earn?
Levi charges customers a fee of $60 just to come to their houses and then $1 per minute that he is there. Levi earned $80 and Tom earned $100.
An equation is a mathematical statement that asserts the equality of two expressions. It consists of two sides, often referred to as the left-hand side (LHS) and the right-hand side (RHS), connected by an equal sign (=). The equal sign indicates that the two sides have the same value or are equivalent.
Levi charges customers $60 as a base fee and then $1 per minute that he spends on the job. Tom charges $40 for a home visit and $3 per minute. Levi and Tom spent the same amount of time working and earned the same amount of money. Let's calculate their earnings.
Let's assume they worked for t minutes each. Levi's earning equation will be:
E1 = 60 + t
Tom's earning equation will be:
E2 = 40 + 3t
Their earnings are the same so:
60 + t = 40 + 3t
60 - 40 = 3t - t
t = 20
So they both worked for 20 minutes. Let's substitute 20 into either of their equations and find their earnings:
E1 = 60 + t = 60 + 20 = $80
E2 = 40 + 3t = 40 + 3(20) = $100
Therefore, Levi earned $80 and Tom earned $100.

On his recent free-throw attempts, Lester made 39 shots and missed 3 shots. What is the experimental probability that Lester will miss his next free-throw attempt?
The experimental probability of Lester missing his next free-throw attempt can be calculated by dividing the number of missed shots by the total number of shots attempted.
Number of missed shots = 3
Total number of shots attempted = 39 + 3 = 42
Experimental probability of missing the next free-throw attempt = (Number of missed shots) / (Total number of shots attempted)
= 3 / 42
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3.
Experimental probability of missing the next free-throw attempt = (3 ÷ 3) / (42 ÷ 3)
= 1 / 14
Therefore, the experimental probability that Lester will miss his next free-throw attempt is 1/14.

A scientist claims that a certain type of fabric is better able to repel water than another. Which option describes an experiment that will produce evidence that will support or refute her claim?.
To gather evidence supporting or refuting the scientist's claim about the fabric's water repellency, an experiment can be conducted by comparing the water repellency of the two fabrics using a standardized testing method, such as the water droplet test.
The experiment can be designed as follows: Select two fabrics, one being the fabric the scientist claims to be better at repelling water and the other being a different fabric for comparison. Cut identical-sized samples from each fabric and ensure they are in the same condition, such as cleanliness and moisture content.
To test the water repellency, a standardized method like the water droplet test can be employed. This involves placing a droplet of water on each fabric sample and observing how the water interacts with the surface. Factors to consider include the rate of absorption, spreading, or beading of the water droplet. Repeat the test multiple times to ensure consistency.
Measurements and observations should be recorded for both fabrics, noting any differences in water repellency. Statistical analysis can be performed to evaluate the significance of the observed variations.
If the fabric claimed to repel water shows consistently higher rates of beading or slower absorption compared to the other fabric, it would provide evidence supporting the scientist's claim. Conversely, if the two fabrics exhibit similar water repellency characteristics, it would challenge the claim.
By conducting this experiment with proper controls and measurements, evidence can be generated to either support or refute the scientist's claim about the fabric's water repellency.
