Answer:
1. 523 cm^3
2. 1.6 ft
Step-by-step explanation:
1. Formula for volume of a sphere is (4/3)(pi)(r^3)
r = 5
(4/3)(3.14)(5^3) ≈ 523
2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)
(1/3)(3.14)(1^2)(2) ≈ 2.0933
Plug this into the formula for volume of a sphere and find r.
2.093 = (4/3)(3.14)(r^3)
r ≈ 0.7937
Multiply by 2 to get the diameter, which is the height of the spherical barrier.
r * 2 ≈ 1.6
Simplify the expression by combining like terms: x + 7x
Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
Step-by-step explanation:
Answer:
[tex]8x[/tex]
Step-by-step explanation:
[tex]x+7x[/tex]
[tex]8x[/tex]
The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

Answer:
Volume = 66
Surface are = 144
Step-by-step explanation:
1. Volume
The formula to find the volume of a triangular prism is the following,
[tex]A=\frac{l*w*h}{2}[/tex]
The following information is given,
lenght = 4
width = 11
hieght = 3
Substitute these numbers into the formula and solve for the heihgt,
[tex]A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66[/tex]
2.Surface area
The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.
The formula to find the area of a rectangle is the following,
[tex]A_r=(lenght)(width)[/tex]
The formula to find the area of a triangle is the following,
[tex]A_t=\frac{(legnth)(width)}{2}[/tex]
Substitute in the give values and add up the results to find the total surface area of the rectangle,
[tex]((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144[/tex]

You are using a hose to fill up your backyard swimming pool on a hot day. Water flows out of the hose at a rate of 6 gallons per minute. In the equation below, m is the number of minutes the hose has been running, and g is the number of gallons of water in the pool.
The relationship between these two variables can be expressed by the following equation:
g=6m,
Identify the dependent and independent variables.
Answer:
The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.
Answer:
g=36
Step-by-step explanation:
so if g=6m you would do 6x6 as 6 gallons per minute and g is the amount in the pool so you times them to get 35 so g=36

Step-by-step explanation:
11% =0,11
=11/100
[tex] \frac{11}{100} [/tex]
Answer:
1° you transform in 11/100, then you divide to get 0,11, then multiply to get 11 and this is the way you transform fraction in percentage

Answer:
[tex]\frac{times}{days}[/tex] = [tex]\frac{20}{5}[/tex] = [tex]\frac{m}{30}[/tex]
you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.
Cross multiply and solve for the variable.
20(30) = 5(m)
600 = 5m
120 = m
So, in 30 days the theatre showed 120 movies.

What is 75% of 16?
Answer:
12
Step-by-step explanation:
16 times 0.75 = 12
Answer:
12
Step-by-step explanation:
75%=3/4.
So, we can simplify it to 3/4 of 16
4/4 of 16 is 16.
So, 3/4 of 16 is 1/4 less than that.
1/4 of 16 is 4. We want 3/4 so we multiply 4*3=12
Hope this helps!

55% = 55/100 = 0.55
55% of 200 = 0.55*200 = 110 people prefer dogs
30% of 200 = 0.30*200 = 60 people prefer cats
Subtract the results: 110-60 = 50

You have a (12x+8) and 55* degree and (8x-3) in a equal triangle right like this /\ and have to solve for x
please help
Answer:
12x + 8 = 12 x 6 + 8 = 80
8x-3 = 8 x 6 - 3 = 44
Step-by-step explanation:
(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)
(8+55-3) + (12x + 8x) = 180( group the variables)
(60) + (20x) = 180
20x = 180 - 60
20x = 120
x = 120/20 = 6
x=6
