You plug -x+16 in for y in x+4y=37 to get x after you multiply x+4y=37 by -1.
-x-4(-x+16)=-37
-x+4x-64=-37
3x-64=-37
3x=27
x=9
Then you plug 9 into either equation to get y.
y=-x+16
y=-(9)+16
y=7
x=9 and y=7
Answer:
9,424.8 cm^3
Step-by-step explanation:
V = A of circle x h
= πr^2 x h
=(3.1416)(10)^2 x 30
=(3.1416)(100) x 30
=314.16 x 30
=9429.8

Answer:
Step-by-step explanation:
we have
where
t is the time in seconds
h is the dolphin's height in feet
we know that
When the dolphin return to the water the value of h(t) is equal to zero
so
For h(t)=0
Simplify

Answer:
16 square inches
16 inches
Step-by-step explanation:
We know the area formula is A = s² and the perimeter formula is P = 4s, where s is the side length.
Here, s = 4, so plug this value into both equations:
A = s²
A = 4² = 16 square inches
P = 4s
P = 4 * 4 = 16 inches
Both blanks are 16.
