Step-by-step explanation:
ans is $351.271875 of total cost
Answer:
D
Step-by-step explanation:
-1.5(-6m+8n) = 9m-12n
3(3m -4n) = 9m - 12n
9m -12n = 9m -12n
-6(-1.5m +2n) = 9m - 12n
-2(-4.5m+ 4n) = 9m - 8n
Answer:
cubic inches
Step-by-step explanation:
Given:
The base of each pyramid is a square with a side length of 5 inches
Height of of pyramid is 9 inches.
To find: volume of the pyramid
Solution:
As the base of each pyramid is a square with a side length of 5 inches,
length of the pyramid (l) = base of the pyramid (b) = 5 inches
Height of of pyramid (h) = 9 inches
Volume of the pyramid
On putting values of l, b and h, we get
cubic inches
When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula
for
0=ax²+bx+c
so for
0=-16t²+25t+3
a=-16
b=25
c=3
so
it has to be a positive time
so it will hit the ground after
seconds
