Answer:
The volume of the prism is <em>864</em><em> </em><em>inches</em><em>^</em><em>3</em>.
Step-by-step explanation:
The basic formula for the volume of a prism is:
V = Ah
where:
V = Volume of prism
A = Area of uniform cross-section or base of prism = 96 inches^2
h = Perpendicular height of prism = 9 inches
Substitute the values given in the question into the formula.
V = 96 × 9
V = 864 inches^3
Answer:
Option D will be correct.
Step-by-step explanation:
The 333 erasers cost $4.41.
We have to determine the cost of 444 erasers.
Let the price of 444 erasers is $x.
Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be 
⇒ 
Therefore, option D will be correct. (Answer)
The independent variable here is b, the number of mats; the dependent var. is p, the cost of b mats. Thus, p = f(b).
Here, 245 units^3 = pi*r^2*(5 units), or
245 units^3
r^2 = ------------------- = 15.61 units^2. Thus, the radius is sqrt(15.61 units^2), or
5(3.14) units 3.95 units. The DIAMETER is d = 2*r = 7.90 units.
Answer:
(64,86.5)
Step-by-step explanation:
find the case where he gets 70 and the case where he gets 79
if his average is 70:
(75+62+85+2x)/5=70
(222+2x)/5=70
222+2x=350
2x=128
x=64
if his average is 79:
(75+62+85+2x)/5=79
(222+2x)/5=79
222+2x=395
222+2x=395
2x=173
x=86.5
