Answer:150
Step-by-step explanation: you see what makes 550 200 plus what 350 then it equal 550 then you see 200 plus what equals 350 150 so that is a 150%
Step-by-step explanation:
I think so option b Is answer
Answer:
a = 7, b = 
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
a × 
= 7 ( divide both sides by )
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° = 
, then
tan60° = 
= 
= 
= ( multiply both sides by b )
b × = 7 ( divide both sides by )
b = 
× 
=
Answer:
Mean = 0.2(100) = 20
Variance = 0.2×0.8×100 = 16
Standard deviation = 4
Yes, np > 5 & nq > 5
Pi*radius squared= area of a circle
3.14*2^2=12.56yd^2
pi*diameter=circumference
3.14*4=12.56yd
area of surface around the cylinder=circumference*height
12.56*6=75.36yd^2
area of surface around the cylinder+ (area of circle*2)= surface area
75.36+(12.56*2)=100.48
the answer should by 100.48 yards squared
hope this helps
