Answer:
paper left = 168.56 units²
Step-by-step explanation:
first, figure the area of the square:
area of square = 28x28 = 784 units²
second, figure the area of the circle:
radius = 1/2of 28 = 14
area of circle = Pi x Radius² = (3.14)(14)² = 615.44 units²
subtract area of circle from area of square:
784 - 615.44 = 168.56 units²
Answer: 60 or something near that sorry if wrong
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, we will eliminate the x, so we multiply the first one by 2.
4x+6y=4
4x-2y=4
So, we have y=0, and we put that in the equations, so x is 1
Answer:
Approximately
7.5

Step-by-step explanation:
Explanation:
We are trying to determine the value of
h
in the compound growth formula
XXX
20
×
(
1
+
0.85
)
h
=
2000
or, simplified:
XXX
1.85
h
=
100
Taking the
log
1.85
of both sides:
XXX
log
1.85
100
With the aid of my trusty spreadsheet:
XXX
h
≈
7.48582192
I hope this helps you
x=42.8+6.9
x=49.7
