Answer:
circle question: 69.66
the other question: 66.8
Step-by-step explanation:
For the circle question:
the circle is inscribed in the square, so the diameter of the circle = side of the square
so we need to find the area of square and circle
then do this
square area - circle area
square area(side×side) = 324
circle area(pi×r^2)≈254.469
so shaded region = 69.66
__________
the other question:
we need to find the area of triangle and the area of the rectangle and add them together
A of Triangle (1/2×base×hight) = 34.32
A of rectangle (width × length) = 31.92
add them, so the answer will be = 66.8
Answer:
∠A = 22°
Step-by-step explanation:
Given:
We take inverse of sine to find angle A.
So, 
°
22.23° rounded to nearest whole degree is 22°.
∴ 
°.
Just count the amount of each letter and write it as a exponent = 3x²y³
Answer:
B, E
Step-by-step explanation:
The function y=1.5+x has two points listed which make the equation true.
(-1.5,0)
y=1.5+x
0=1.5+-1.5
0=0
(4.5,6)
y=1.5+x
6=1.5+4.5
6=6
First lets figure out 2 and 1/4 as a decimal
2 and 1/4 = 2.25
So now we subtract
5 - 2.25 = 2.75
She is 2.75 miles away from her starting point
