Answer:
cosA = 0.6
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract sin²A from both sides )
cos²A = 1 - sin²A ( take the square root of both sides )
cosA = ± 
Since only the positive value is required , then
cosA = 
= 
= 
= 0.6
Answer:
y=-4x+11
Step-by-step explanation:
formula=
y=mx+B
find m
formula y2-y1/x2/x1
-5--1/4-3=-4/1=
-4 is your m
find b
-1=-4(3)+b
-1=-12+b
11=b
3.subsitiute into y=mx+b
Answer= 40%
40% of call are for air conditioners
1/5 of calls are for heaters
First, lets convert 1/5 into a decimal, and then a percent value.
1/5=0.20=20%
20% of calls are for heaters
100% represents the amount of service calls Mike receives.
100%-40%-20%=
100%-60%=40%
40% of the service calls Mike receives are other calls.
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad
Hi! :)
This question states that four families each brought the same number of chairs. We know that 27 chairs are needed overall and 3 are still needed after the four families' contributions.
Knowing this, you can figure out that you could do 27-3. This equals 24, so you would then just divide 24 by 4, since there are 4 families.
Your final answer should be that each family brought 6 chairs.
Hope this helps!
