Answer:Explanation: The area of a circle is πr2 where r is the radius. Dividing both sides by π we find r2=16=42 and hence r=4
Step-by-step explanation:
Answer:
∠RQS = 156
Step-by-step explanation:
m∠TQS = 24
∠TQS and ∠RQS are linear pair. Linear pair are two adjacent angles and their sum is 180
∠TQS + ∠RQS = 180
24 + ∠RQS = 180
∠RQS = 180 - 24
∠RQS = 156
Option A:

Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A: 
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So,
is the correct way to complete the statement.
Option B: 
In the given image length of AB ≠ EG.
So,
is the not the correct way to complete the statement.
Option C:
In the given image length of AB ≠ FH.
So,
is the not the correct way to complete the statement.
Option D:
In the given image length of AB ≠ HE.
So,
is the not the correct way to complete the statement.
Hence,
is the correct way to complete the statement.
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
Answer: D) 10 jerseys
Step-by-step explanation:
Let j represent the number of jerseys and C for total cost
Local company eqn: C = 5.25j + 45
Online company eqn: C = 7.75j + 20
Set both sides equal to solve:
5.25j + 45 = 7.75j + 20
5.25j - 7.75j = 20 -45
- 2.5j = -25

j = 10
Therefore, the cost is the same for both companies when 10 jerseys are sold
