Answer:

Step-by-step explanation:

8.00 to 10.00 yes the relationship is proportional because it is the eniquality between two ratios 8.00 and 10.00

Final answer:

This detailed answer explains the proportional relationship between the cost and retail price of t-shirts in the given data table, provides the equation representing the relationship, and predicts the retail price for a t-shirt costing the store $9.50.

Explanation:

a. Is the relationship proportional? Yes, the relationship is proportional because the ratio between the cost and the retail price remains constant. This can be seen by calculating the cost-to-price ratios for each pair of values. If the ratios are the same, the relationship is proportional.

b. Write an equation that represents the relationship: The equation for the relationship is y = 1.25x + 0.75 where y represents the retail price and x represents the cost to the store.

c. Predict the retail price for a t-shirt that cost the store $9.50: Substituting $9.50 for x in the equation gives us a predicted retail price of $11.88. The store is likely to charge $11.88 for a t-shirt that cost them $9.50.

The fourth term of the arithmetic sequence 4, 8, 12, 16, 20, 24, ... is 16, which can be found either by adding the common difference to the third term or by using the formula for the nth term of an arithmetic sequence.

The fourth term of the sequence 4, 8, 12, 16, 20, 24, ... can be determined by looking at the pattern of the sequence. This sequence is an arithmetic sequence, where each term increases by the same amount, which is 4 in this case. To find the fourth term, we can simply add the common difference (4) to the third term (12), which gives us 16. Alternatively, we can use the formula for the nth term of an arithmetic sequence, which is an = a1 + (n - 1)d, where a1 is the first term, d is the common difference, and n is the term number. Using this formula with a1 = 4, d = 4, and n = 4, we again get the fourth term as 16.

Final answer:

To find dy/dx for y=log(tan(2x)), we can use the chain rule: dy/dx = (2sec²(2x))/tan(2x).

Explanation:

To find dy/dx for y = log(tan(2x)), we can use the chain rule. Let's break it down step by step:

First, we identify the inner function, which is u = tan(2x).

Next, we find the derivative of the inner function with respect to x: du/dx = 2sec²(2x).

Then, we identify the outer function, which is y = log(u).

Finally, we find the derivative of the outer function with respect to u and multiply it by the derivative of the inner function with respect to x: dy/dx = (1/u) * (du/dx) = (2sec²(2x))/tan(2x).

Answer:

y<2 i got it right on my test

Step-by-step explanation:

3x - y=0

5x + 2y=22

Solve the first equation for y

3x - y =0

-y = -3x

so y = 3x

Now plug in y=3x in second equation

5x + 2y=22

5x + 2(3x) =22

5x + 6x = 22

11x = 22

Divide by 11 on both sides

x= 2

Plug in 2  for x and find out y

y = 3x

y = 3(2) = 6

so our answer is correct.

Here are two ways of solving this problem.

Method A. Using fractions.

You will need 3 times as much milk, so you need to multiply 3 by 2 3/4.

First, convert 2 3/4 into an improper fraction.

2 3/4 = 2 + 3/4 = 2/1 + 3/4 = 8/4 + 3/4 = 11/4

Now multiply 11/4 by 3.

3 * 11/4 = 3/1 * 11/4 = 33/4

Now convert 33/4 into a mixed numeral.

33/4 = 8 1/4

Answer: 8 1/4

Method B. Using decimals.

You will need 3 times as much milk, so you need to multiply 3 by 2 3/4.

First, convert 2 3/4 into a decimal number.

2 3/4 = 2.75

Now multiply 2.75 by 3.

3 * 2.75 = 8.25

Now convert 8.25 into a mixed numeral.

8.25 = 8 + 0.25 = 8 + 1/4 = 8 1/4

Answer: 8 1/4

Correct answer is: [tex]8\frac{1}{4}[/tex] cups milk needed if the recipe is tripled.

Solution:-

Given that a recipe calls for [tex]2\frac{3}{4}[/tex] cups of milk.

Let us convert that mixed fraction to proper fraction.

[tex]2\frac{3}{4}=\frac{2*4+3}{4}=\frac{11}{4}[/tex]

If the recipe is tripled, milk also should be tripled.

Hence amount of milk = [tex]3*\frac{11}{4}=\frac{33}{4}=8\frac{1}{4}[/tex]

To cover one cake, we need approximately 1.33 times the amount of frosting that covers 1/8 of the container.

To find out how much frosting is needed to cover one cake, we need to find the ratio between the amount of frosting and the amount of cake that is covered. We are given that 1/8 of the frosting container covers 1/6 of the cake. To simplify this ratio, we can find a common denominator, which is 24. So, 1/8 of the frosting container is equivalent to 3/24 and 1/6 of the cake is equivalent to 4/24.

Since the ratio is now 3/24 frosting to 4/24 cake, we can say that for every 3 parts of frosting, we need 4 parts of cake. So, if we want to cover one cake, we would need 4/3 times the amount of frosting, which is approximately 1.33 times the amount of frosting needed to cover 1/8 of the container.

Therefore, to cover one cake, we need approximately 1.33 times the amount of frosting that covers 1/8 of the container.

Final answer:

To make as many pillowcases as Hasan can with 18 3/4 yards of fabric, we divide the total amount of fabric by the amount needed for one pillowcase and then find the remainder.

Explanation:

To find out how many pillowcases Hasan can make, we need to divide the total amount of fabric he has (18 3/4 yards) by the amount of fabric needed to make one pillowcase (3 1/6 yards).

First, let's convert 18 3/4 yards to an improper fraction: 18 3/4 = 75/4.

Next, let's convert 3 1/6 yards to an improper fraction: 3 1/6 = 19/6.

Now, we can divide 75/4 by 19/6 using the division of fractions:  (75/4) ÷ (19/6) = (75/4) x (6/19) = 450/76 = 75/19.

So Hasan can make 75/19 pillowcases. To find out how many yards of fabric will be left over, we need to subtract the amount used for the pillowcases from the total amount of fabric. Let's multiply the number of pillowcases (75/19) by the amount of fabric used per pillowcase (3 1/6 yards): (75/19) x (19/6) = 75/6 = 12 3/6 yards.

Therefore, Hasan will have 12 3/6 yards of fabric left over.
