The volume of a pyramid, V, is calculated using the formula V = 1/3 AH, where A is the area of the base and H is the height of the pyramid.
Rearrange the formula to solve for the base area (A)
Answer:
A= 3V/H
Step-by-step explanation:
V=1/3 AH
multiply 3 on both sides
3V=AH
divide both sides by H
3V/H=A
Joes mother gave him 1/3 of the money in her purse. His father gave him 5.00. If they gave joe a total of 12.00, How much money did his mother have in her purse. Joes mother had $ money in her purse (Enter a number only and make sure to include the decimal and 2 numerical decimal places.)
Answer:
$21Step-by-step explanation:
let the money in her purse be $x
1/3 of the money is 1/3x
Since his father gave him $5 and the total amount became $12
the expression for the total amount would be
12= 1/3x+5
We can now solve for x
12-5= 1/3x
1/3x= 7
cross multiply we have
x= 7*3
x= $21
Therefore the money in joes mother's purse is $21

2m - n =8 Solve for n
Answer:
[tex] \boxed{\sf n = 2m - 8} [/tex]
Step-by-step explanation:
Solve for n:
⇒2m - n = 8
Subtract 2 m from both sides:
⇒2m - 2m - n = 8 - 2m
2m - 2m = 0:
⇒-n = 8 - 2 m
Multiply both sides by -1:
⇒-n × (-1) = (8 - 2m) × (-1)
⇒n = 2m - 8
The required value of n is equal to n = 2m - 8.
An expression is given in the question ; i.e., 2m - n = 8.
We have to find the value of the 'n' .
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
The given expression is 2m - n = 8.
Let's solve it to get the value of n.
The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.
So ,
2m - n = 8 can be written as ;
2m = 8 + n
or
n = 2m - 8
Thus , the required value of n is equal to n = 2m - 8.

Answer:
144 cm²
Step-by-step explanation:
A prism's surface has 2 triangles & 3 rectangles.
In both the triangles , length of :
Perpendicular = 4 cm
Base = 6 cm
So , Area of both triangles = [tex]2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2[/tex]
In the 3 rectangles ,
Length = 8 cm
Width = 5 cm
So , Area of the rectangles = [tex]3( Length * Width) = 3(8 * 5) = 120 cm^2[/tex]
Hence the total surface area of the prism is = 120 + 24 =144 cm²

Answer: 26
Step-by-step explanation:
x is equal to 4 so we will input 4 into the expression for x and solve.
2(4)^2 - 3(4) + 6
2(16) - 12 + 6
32 - 12 + 6
