To find the length of UV, we can use the Law of Cosines, which states that in a triangle, the square of one side is equal to the sum of the squares of the other two sides minus twice the product of the lengths of those two sides multiplied by the cosine of the included angle.
Let's denote the length of UV as x. According to the given information, we have TU = 7.1 feet and ZT = 24º. ZV is given as 90º, indicating that triangle TUV is a right triangle.
Applying the Law of Cosines, we can write:
x^2 = (7.1)^2 + UV^2 - 2(7.1)(UV)cos(24º)
Since ZV = 90º, the cosine of 90º is 0, so the equation simplifies to:
x^2 = (7.1)^2 + UV^2
Now, we substitute the given values:
x^2 = (7.1)^2 + x^2
Simplifying, we get:
0 = (7.1)^2

Walmart sells 1.5 liters of Lemonade for 75 cents, but K-Mart sells 2.72 liters of Lemonade for $1.40. Which store is the cheaper buy per unit?
Walmart is the cheaper buy per unit of lemonade.
To determine which store offers a cheaper buy per unit of lemonade, we need to compare the prices per liter.
Walmart sells 1.5 liters of lemonade for 75 cents.
Therefore, the price per liter at Walmart is:
Price per liter at Walmart = 75 cents / 1.5 liters
Price per liter at Walmart = 50 cents / liter
K-Mart sells 2.72 liters of lemonade for $1.40.
Therefore, the price per liter at K-Mart is:
Price per liter at K-Mart = $1.40 / 2.72 liters
Price per liter at K-Mart ≈ 51.47 cents / liter (rounded to two decimal places)
Comparing the prices per liter, we can see that Walmart offers a lower price per liter compared to K-Mart.
Therefore, Walmart is the cheaper buy per unit of lemonade.

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 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%.

The rate of discount is 30%. The regular price of the television set is Php 1580, and it is being sold at a discount of 30%.
To find the sale price, we can use the formula:
Sale price = Regular price - (Discount rate × Regular price)
Substituting the given values, we get:
Sale price = 1580 - (0.30 × 1580)
Sale price = 1580 - 474
Sale price = 1106
Therefore, the sale price of the television set is Php 1106. This means that Mr. Edwin Lazo paid Php 13,600.00 for an item that originally cost Php 1580.00 but was on sale at Php 1106.00.
To calculate the rate of discount, we can use the following formula:
Discount rate = (Regular price - Sale price) / Regular price x 100%
Substituting the given values, we get:
Discount rate = (1580 - 1106) / 1580 x 100%
Discount rate = 474 / 1580 x 100%
Discount rate = 0.3 x 100%
Discount rate = 30%

When rolling a biased dice 100 times, the expected number of odd outcomes is three times the expected number
of even outcomes. Find the probability of an odd outcome.
The probability of an odd outcome when rolling a biased dice can be found by dividing the expected number of odd outcomes by the total number of possible outcomes. In this scenario, the expected number of odd outcomes is three times the expected number of even outcomes. Therefore, the probability of an odd outcome is 3/4 or 0.75.
To find the probability of an odd outcome, we first need to determine the expected number of odd and even outcomes. Let's denote the expected number of odd outcomes as O and the expected number of even outcomes as E. According to the given information, O = 3E.
Since the dice is biased, we can assume that the probabilities of rolling an odd or even number are not equal. Let's represent the probability of rolling an odd number as p and the probability of rolling an even number as q.
The total number of outcomes when rolling a dice is 6 (1, 2, 3, 4, 5, 6). Therefore, we have the equation: O + E = 6.
Substituting O = 3E, we can rewrite the equation as: 3E + E = 6, which simplifies to 4E = 6.
Solving for E, we find E = 6/4 = 1.5.
Since O = 3E, we have O = 3 * 1.5 = 4.5.
The probability of an odd outcome can be calculated as O/(O + E), which is 4.5/(4.5 + 1.5) = 4.5/6 = 3/4 or 0.75.

Caleb is 60 inches tall at the beginning of the school year. now he is 65 inches tall. what percent did his height increase?
Caleb's height increased by 8.33%. The initial height of Caleb was 60 inches, and his final height is 65 inches.
To calculate the percentage increase in Caleb's height, we need to find the difference between his final height and initial height, and then express it as a percentage of his initial height.
The initial height of Caleb was 60 inches, and his final height is 65 inches.
To find the difference in height, we subtract the initial height from the final height:
Height increase = Final height - Initial height
Height increase = 65 inches - 60 inches
Height increase = 5 inches
Next, we calculate the percentage increase by dividing the height increase by the initial height and multiplying by 100:
Percentage increase = (Height increase / Initial height) * 100
Percentage increase = (5 inches / 60 inches) * 100
Percentage increase ≈ 8.33%

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.

Nick found the quotient of 8. 64 and 1. 25 × 105. His work is shown below. 1. (8. 64 × 101) (1. 25 × 105) 2. (8. 64 1. 25 ) (101 105 ) 3. 6. 912 × 10–4 Analyze Nick’s solution. Is he correct? If not, what was his mistake? Yes, Nick is correct. No, the power multiplied to 8. 64 should have an exponent of 0. No, he needed to subtract the coefficients. No, he needed to add the exponents.
Nick's solution is incorrect. His mistake lies in step 2 of his work.
In step 2, Nick incorrectly multiplies the coefficients (8.64 and 1.25) and also multiplies the exponents (101 and 105). However, when dividing two numbers written in scientific notation, the coefficients should be divided, not multiplied, and the exponents should be subtracted, not added.
The correct steps for dividing 8.64 by 1.25 × 10^5 are as follows:
1. Rewrite the numbers in scientific notation:
8.64 = 8.64 × 10^0
1.25 × 10^5 = 1.25 × 10^5
2. Divide the coefficients:
8.64 ÷ 1.25 = 6.912
3. Subtract the exponents:
0 - 5 = -5
Therefore, the correct quotient is 6.912 × 10^-5, not 6.912 × 10^-4 as stated in Nick's solution.

a blue print of a plot of land has a scale of 1 1/4 centimeters to 3 1/4 meters. The length of land measures 20 centimeters on the blueprint. If l represents the length of the actual piece of land, what is l?
According to the given scale, 1 1/4 centimeters on the blueprint represents 3 1/4 meters in reality. The length of land measures 20 centimeters on the blueprint. To find the actual length of the land, denoted by "l," we need to set up a proportion and solve for "l." Therefore, the actual length of the land, denoted by "l," is 65 meters.
Let's set up the proportion based on the given scale:
(1 1/4 cm) / (3 1/4 m) = (20 cm) / (l)
To solve for "l," we cross-multiply and then divide:
(1 1/4 cm) * (l) = (3 1/4 m) * (20 cm)
(5/4 cm) * (l) = (13/4 m) * (20 cm)
(l) = [(13/4 m) * (20 cm)] / (5/4 cm)
Simplifying the expression, we get:
(l) = (260/4 m*cm) / (5/4 cm)
(l) = (260/4 m)
(l) = 65 m
Therefore, the actual length of the land, denoted by "l," is 65 meters.

Kareem was doing research for a report about the longest rivers on Earth. He read that the Nile River is 4.16 × 10³ miles long. How should Kareem write the length of the Nile River in standard form on his report?
Kareem should write the length of the Nile River in standard form as 4160 miles.
To write the length of the Nile River in standard form, we need to express it as a number multiplied by a power of 10.
Given: Length of the Nile River = 4.16 × 10³ miles
In standard form, we want a number between 1 and 10 multiplied by a power of 10. To achieve this, we can move the decimal point three places to the right since we have a positive exponent of 10³.
Moving the decimal point three places to the right gives us:
4.16 × 10³ = 4160
Therefore, Kareem should write the length of the Nile River in standard form as 4160 miles.

Farid has two types of sticks: short ones, measuring 1 cm and long ones, measuring 3 cm. With which of the combinations below can he make a square, without breaking or overlapping the sticks?
Farid can make a square by using a combination of two short sticks and two long sticks.
To form a square without breaking or overlapping the sticks, the length of each side of the square must be equal. In this case, we have two types of sticks: short ones measuring 1 cm and long ones measuring 3 cm.
To determine which combinations can form a square, we need to consider the lengths of the sides and the total length of the sticks.
1. Using only short sticks (1 cm each):
To form a square, we need four equal sides. Since each short stick measures 1 cm, the total length of the four sides would be 4 cm. This combination does not work as the total length is too small to form a square.
2. Using only long sticks (3 cm each):
Similarly, using only long sticks would result in a total length of 12 cm for the four sides. This combination also does not work as the total length is too large to form a square.
3. Using a combination of short and long sticks:
In this case, we can combine short and long sticks to create a square. For example, using two short sticks and two long sticks would give us a total length of 2 cm + 2 cm + 3 cm + 3 cm = 10 cm. This combination can form a square with each side measuring 2.5 cm.

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.

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.
They are typically collected at toll booths or through electronic systems, and the revenue generated is used for the maintenance and construction of the infrastructure.
