Answer: 2.5 ft
Step-by-step explanation:
The volume of a rectangular prism is given by the following formula:
(1)
Where:
is the length of the base
is the width of the base
is the height of the prism
On the other hand, tha area of a rectangle is:
(2)
Then, we can rewrite (1) in terms of (2):
(3)
Now, we know the value of the volume and the area of the base:
Substituting these values in (3):
(4)
Isolating :
This is the height of the truck
First, you would need to determine how much it would cost her if it was three for $1 or seven for 42.
Three for $1:
21 ÷ 3 = 7
7 × $1.00 = $7.00
Seven for $2:
21 ÷ 7 = 3
3 × $2.00 = $6.00
Now, all you would need to do is find the difference.
$7.00 - $6.00 = $1.00
Jackie would have saved A. $1.00.
I hope this helps!
The sum of the 3 angles of a triangle is 180 °
the sum of the arc of a circle is 360°
⇒ the inscribed angle = the angle measure of the arc it intercepts/2
