1. A goat is tied to the corner of a rectangular shed in a large field full of grass. The rope is 2 yards long and a plane view (from above) of the shed and field is shown below. Use this information for Parts A and B below.
Part A: Calculate the area of grass that the goat can eat.
Part B: What length of rope would enable the goat to eat 30 square yards of grass? Show all your reasoning.

Answers

Answer:

Step-by-step explanation:

Step one:

Given data

the length of the rope =2yards----the radius

(Note that the goat can only move in a circular path)

the area the goat can eat is the area of the circle it can cover

1. A= πr^2

A=3.142*2^2

A=3.142*4

A=12.57square yards

Step two:

given that the area A=30 square yards

we want to solve for the radius r

A= πr^2

30=3.142*r^2

r^2=30/3.142

r^2=9.55

r=√9.55

r=3.09 yard

The length is approximately 3 yards

If $7,500 investment earns $450 over 3 years what's the interest rate

Answers

Answer:

Rate is 2%

Step-by-step explanation:

Step one:

given data

Principal= $7500

Simple interest= $450

time=3 years.

Applying the simple interest formula which is

SI=PRT/100

Step two:

divide both sides by 22500

R=45000/22500

R=2%

Step-by-step explanation:

The triangle PQR will become LMN when rotated 90 degrees

however the inside angles is missing for R, to solve:

since the sum of 3 angles inside a triangle is 180, then

m∡RPQ + m∡PRQ + m∡QRP = 180

m∡PRQ = 180 - 50 - 100 = 30°

the problem is asking for the angle ∡LNM which is the same as ∡PRQ

m∡PRQ = ∡LNM = 30

Abargain clothing store is selling 5 shirts for $20.
Louis said, "I can buy 2 shirts for $8."
William said, "I can buy 1 shirt for $4."
Which statement is TRUE?
A
Only Louis's statement is true.
B
Only William's statement is true.
Both Louis and William's statements are true
D
Neither Louis nor William's statements are true.

Answers

Answer: Both of their statements are true. Explanation: If you can buy 5 shirts for $20, that means the unit price would be $4 per shirt. (to find the unit price just divide the cost by the quantity) So, it is true that you can buy one shirt for $4 and 2 shirts for $8. Hopefully this helps.
