Saniya bought a new outfit for the holidays. She paid $15.00 for the shirt, $32.00 for the pants and $75.00 for the shoes. If she had a 30% off coupon, how much was her subtotal?

### Answers

**Answer:**

$99.5

**Step-by-step explanation:**

Add up all the dollar amounts and subtract 30%

**Answer:**

Subtotal: $122 Total: $36.60

**Step-by-step explanation:**

Since you're only looking for the subtotal and not the actually total, you just have to add $15.00 + $32.00 + $75.00 and you should get $122. Although if you were looking for the total then you would have to know what 30% of 122 is and you should get 36.60 as the result so it would cost $36.60

Z-m=z+bx , solve for b

### Answers

**Answer:**

b= (Z-m-z)/(x)

**Step-by-step explanation:**

Z-m=z+bx

Z-m-z=bx [Transpose z of R.H.S to L.H.S] / [Substract z from L.H.S and R.H.S]

(Z-m-z)/(x)=b [Divide by x on both sides i.e, L.H.S and R.H.S]

b= (Z-m-z)/(x)

The Gregory family is preparing for a family reunion. They think they will need 15 juice boxes for every 5 children who attend. How many juice boxes will they need if they are expecting 26 children?

### Answers

**Answer: 78 juice boxes **

**Step-by-step explanation:**

The Gregory family thinks that they will need 15 juice boxes for every 5 children.

The number of juice boxes they will need for every child is:

= Number of juice boxes for 5 children / 5

= 15 / 5

= 3 juice boxes per child

If they are expecting 26 children, they will need:

= 3 * 26

**= 78 juice boxes **

A section of land measuring 2 2/5 acres is divided equally among three brothers. How many acres will each brother receive? *

### Answers

**Answer:**

**12/15 acres of land **

**Step-by-step explanation:**

Total measure of land = 2 2/5acres

Total brothers = 3

Amount of acres each brothers will receive = Total measure of land/Total brother

Amount of acres each brothers will receive = (2 2/5)/3

Amount of acres each brothers will receive = 2 2/5 ÷ 3

Amount of acres each brothers will receive = 12/5 ÷ 3

Amount of acres each brothers will receive = 12/5 * 1/3

Amount of acres each brothers will receive = 12/15

**Hence each brother will receive 12/15 acres of land **

The chubby bunny weighs 5 pounds, and it gains 3 pounds per year. The fat cat weighs 19 pounds, and it gains 1 pound per year. When will the two animals weigh the same amount?

### Answers

**Answer: 7 years **

**Step-by-step explanation:**

The Chubby bunny currently weighs 5 pounds but is increasing by 3 pounds per year. Assuming we wanted to find the weight in a given year, we can assume that given year is x. The expression would be:

= 5 + 3x

The fat cat weighs 19 pounds and gains by 1 pound a year.

Expression is:

= 19 + 1x

Equate the two equations together and find x:

5 + 3x = 19 + 1x

3x - 1x = 19 - 5

2x = 14

x = 14/2

**x = 7 years **

One airplane located 200km north and 50km east of an airport. A second plane at the same altitude is located 30km north and 100km west. The distance between the planes is closet to:

### Answers

Answer: 200

Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation

170^2 + 150^2 = c^2

28900 + 22500 = c^2

51400 = c^2

√51400 = √c^2

~226 = c

They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.
