Answers

Answer 1
1 width is 64 cm
2 option 2
3 28.5
4 175
5 224
Answer 2

1. A kite has a width to length ratio of 4:5, so let the width be 4x and the length be 5x. We know that the length is 80 cm. 80 = 5x

Divide by 5.

16 = x.

Now, the width is 4x.

16 times 4 is 64.

The width is 64.

2. Find the unit rate for each juice. The unit rate is ml / dollar.

The first juice has a unit rate of 150 / 1.

The second has a unit rate of 500 / 1.75.

The third has a rate of 1000 / 4.

The fourth has a rate of 2000 / 7.25

Put all values into a calculator. (First: 150, Second: 285.714285, Third: 250, Fourth: 275.862068966)

Whichever one can buy the most ml for a dollar is the best buy.

In here, that is the SECOND rate, which is 1.75 for 500 ml.

She earns 3% commission on all her sales, so if s represents her sales, she'd earn .03s. Inhere, she sells $950 in total. That is her total sales.

So you plug $950 into the equation as s.

.03 (950) = 28.5

She earned $28.50.

Poor Maya!

3. You set it up in ratios. She needs 250 mL of milk for every 325 mL of pancake mix. 250 milk / 325 mix.

But she only has 225 mix.

So you set up 250 milk / 325 mix = M milk / 225 mix

As in all proportions, you cross multiply.

250 x 225 = 325 x M

56250 = 325M

Divide by 325 on both sides.

173.076923077 = M

She needs about 175 mL. The fourth choice.

4. There are a total of 1120 spectators, made of only home team fans and visiting team fans.

There is a total of 100% of people, and 80% are supporters of the home team, so to find the supporters of the visiting team you subtract 100% by 80%.

100 - 80 = 20.

So 20% of the spectators are supporters of visiting team. Now 20% of the total, and 20% = .20.

.20 x 1120 = 224

224 people are fans of the visiting team.

5. A 500-mL bottle of insect repellent has 22 mg of DEET, a chemical used to keep mosquitos away. The same insect repellent sells in 710-mL bottles. Which of the following proportions can be used to find the amount of DEET in the larger bottle? *

If a 500 mL bottle has 22mg of DEET, then 500ml / 22mg

So set up the equation 500 / 22 = 710 / x

Now, cross multiply.

500x = 710 times 22.

500x = 15620

Divide by 500.

x = 31.24

Other possible proportions are:

22 / x = 500 / 710

x / 22 = 710 / 500

22 / 500 = x / 710

Hope this helps and hope I get Brainliest! Lol :)

How to complete the table of values?

The function is given as:

[tex]y = sin(x)[/tex]

From the table, we have:

sin(π) = 0

Next, we calculate the value of y for other values of x

When x = 7π/6, we have:

sin(7π/6) = -1/2

When x = 5π/4, we have:

sin(7π/6) = -√2/2

When x = 4π/3, we have:

sin(4π/3) = -√3/2

Hence, the values that complete the table are -1/2, -√2/2 and -√3/2

Answer:

1, 210.

2. 72 minutes.

3. 42 minutes

4. 2 inches.

5. 3 cents.

Step-by-step explanation:

1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.

2.  Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.

3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.

4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.

5. So here you have to find the unit rate. Divide the price by the quantity.

4.86/16.2=0.297530865

Round the number up, which would be 3. So it would be 3 cents

Solve the system of equations..

Answers

Answer:

x = 8

y = 53

Step-by-step explanation:

Sub y = x + 45 into the second equation

x + 45 = 5x + 13

Rearrange by collecting the like terms

45 - 13 = 5x - x

32 = 4x

Divide both sides by 4

x = 8

Sub x = 8 into first equation (y = x + 45)

y = 8 + 45

y = 53

X=8 and Y =53 are the values
