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

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 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
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.
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)

180 is the median of the entire data.
The upper half of the data (200, 220, 240)
has the median 220.
Interquartile Range = 220 - 140 = 80.
