Three times minus seven equals minus twenty one.
We know that
[volume of a cone]=pi*r²*h/3
r=2 in
h=6 in
[volume of a cone]=pi*2²*6/3------> 25.12 in³
1 ft³---------> 1728 in³
then
X------------> 25.12 in³
X=25.12/1728-----> x=0.014537 ft³
if 1 ft³--------------------> cost $5
0.014537 ft³-----------> X
X=0.014537*5-----> x=0.073
the answer is
<span>the total value of the substance in the container is $0.07</span>
Answer:
= 1 1/3 miles or 1. 336 miles
Step-by-step explanation:
if 1 1/4 (5/4)hrs = 1 2/3 (5/3)miles or if 1.25hrs = 1.67miles
1 hr =<u> 1 hr x 5/3miles</u> or 1 hr = <u>1hr x 1.67miles</u>
5/4hrs 1.25hrs
= <u>1 1/3 miles</u> or <u> 1. 336 miles</u>

Answer:
2 and -3
Step-by-step explanation:
2x^2=4x
4x+2x=12
6x=12
how many times does 6 go into 12?
right, 2 times!
x=2
---
2x^2+2x-12=0
x^2+x-6=0
(x+3)(x-2)=0
X=-3 and 2
