Follow the volume of a rectangular prism formula which is l*b*h.
It will equal to 3000cm^3
A box in the shape of a rectangular prism is approximately 9 inches long,has an equilateral triangle shaped base with side lengths of 3 inches. The height of the triangular shaped base is 2.5 inches. How many cubic inches of styrofoam peanuts can can be place inside the container?
Answer:
33.75 cubic inches of styrofoam can be placed inside the container.
Step-by-step explanation:
Based on given information, the volume of the prism ([tex]V[/tex]), in cubic inches, is determined by using this formula:
[tex]V = \frac{1}{2}\cdot b\cdot h \cdot l[/tex] (1)
Where:
[tex]b[/tex] - Base of the triangular face, in inches.
[tex]h[/tex] - Height of the triangular face, in inches.
[tex]l[/tex] - Length of the prism, in inches.
If we know that [tex]b = 3\,in[/tex], [tex]h = 2.5\,in[/tex] and [tex]l = 9\,in[/tex], then the volume of the prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h \cdot l[/tex]
[tex]V = 33.75\,in^{3}[/tex]
33.75 cubic inches of styrofoam can be placed inside the container.

Answer:
87°
Step-by-step explanation:
Since this is a triangle, triangles add up to 180°
Since we know the 2 angles, we are able to find a
180 - 36 - 57 = 87

I WILL MARK AS BRAINLIST The quantities x and y are proportional Find the constant of proportionality (r) in the equation y=rx
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
[tex]\frac{4.5}{9}[/tex] = r , that is
r = [tex]\frac{1}{2}[/tex]

33% of US adults say they are more likely to make a purchase during a sales tax holiday you randomly select 10 adults find the probability that the number of adults who say they are more likely to make purchases during the sales tax holiday is exactly 2
Answer:
0.199
Step-by-step explanation:
p = 33% = 0.33
1 - p = 1 - 0.33 = 0.67
Using binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 2) = 10C2 * 0.33^2 * 0.67^8
P(x = 2) = 45 * 0.1089 * 0.0406067677556641
P(x = 2) = 0.19899346538663192205
P(x = 2) = 0.1989
P(x = 2) = 0.1990

How much do I have to deposit today in order to have $5000 in 5 years if interest is 8.5% compounded annually?
Answer:
PV= $3,402.9
Step-by-step explanation:
Giving the following formula:
Future Vale (FV)= $5,000
Number of years (n) 5 years
Interest rate (i)= 8.5% compounded annually
To calculate the initial investment (PV), we need to use the following formula:
PV= FV / (1 + i)^n
PV= 5,000 / (1.085^5)
PV= $3,402.9
