The height of a prism with equilateral triangular base is 25 cm. If the perimeter of the base of the prism is 18 cm, find the volume
Answer:
450[tex]cm^{3}[/tex]
Step-by-step explanation:
The volume of prism is Base times the height.
The Base you count from surface area. The formula is a*b/2. The a is 18/3, because you have the equilateral triangle. So you count 6*6/2 and get 18 square cm.
After that you just multiply 18 and 25 and get 450[tex]cm^{3}[/tex]
I hope this is right
The volume of the prism given with a base of equilateral triangle is 389.71 cm³.
What is the volume of a prism?The volume of a prism is the product of the base area and the height of the prism.
The base of the prism is an equilateral triangle that has a perimeter of 18 cm.
Therefore, each side of the prism is
= (perimeter/3)
= (18/3) cm
= 6 cm
Now, the base area of the triangle is
= (√3/4) × (side)²
= (√3/4) × (6)² cm²
= 9√3 cm²
Now, the volume of the prism is
= base area × height
= 9√3 × 25 cm³
= 225√3 cm³
= 389.71 cm³

Given f(x) = 1/2(4 – x)2, what is the value of f(16)?
Step-by-step explanation:
Just replace x with 16....
f (x) = 1/2 (4-x) 2
f (16) = 1/2 (4-16) 2
f (16) = (2 - 8) × 2
f (16) = -6 × 2
f (16) = -12

The expression 8x+2 factored using the GCF is
The expression 8x+2 factored using the GCF is 2(4x + 1)
Equations are expressions separated by an equal sign
Given the expression 8x + 2
First we need to find the factors of each terms
8x = 2 * 4 * x
2 = 2 * 1
From bot factors, we can see that 2 is common. Factoring out 2 from the expression will give;
8x + 2 = 2(4x + 1)
Hence the expression 8x+2 factored using the GCF is 2(4x + 1)

Submit
Reset
Answer:
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.
Step-by-step explanation:
Given:
First week
x gallons of gas at $2.39 per gallon
x gallons = $2.39x
Second week
3 fewer gallons of gas than the first week at $2.49 per gallon
x - 3 gallons = $2.49(x-3)
Total spent = $46.21
$2.39x + $2.49(x-3) = $46.21
2.39x + 2.49x - 7.47 = 46.21
4.88x - 7.47 = 46.21
Add 7.47 to both sides
4.88x - 7.47 + 7.47 = 46.21 + 7.47
4.88x = 53.68
Divide both sides by 4.88
x = 53.68/4.88
= 11
x = 11
First week = x = 11 gallons
Second week
= x - 3
= 11-3
= 8 gallons
Therefore,
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.

The answer could vary. it really just depend on how much of the area he is planning on using.
For all we know, he could use all of either the 15ft or the 3 cm to draw the width.
Answer: The width of 10 lanes in the drawing will be 10 cm
Step-by-step explanation: If 3 cm = 15 ft, divide both sides by 3 to ro finf that 1 cm will represent 5 ft.
If each lane is 5 ft, the width on the drawing will be 1 cm for each lane.
10 lanes will be 10 cm.
And the 60 ft length will be 6 cm in the drawing.

A theater group made appearances in two cities. The hotel charge before tax in the second city was $500 higher than in the first. The tax in the first city was 5.5%, and the tax in the second city was 7.5%. The total hotel tax paid for the two cities was $492.50. How much was the hotel charge in each city before tax?
Answer:
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $4000
Step-by-step explanation:
Let the amount before tax at the first hotel be x
The amount at the second hotel will be x+500
The tax in the first city was 5.5% = 0.055
the tax in the second city was 7.5% = 0.075
Hence, we have
0.055(x) + 0.075(x + 500) = $492.50
0.055x + 0.075x +37.5 = 492.50
0.13x = 492.50 -37.5
0.13x = 455
x = 455/0.13
x = $3500
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $3500 + $500
= $4000
