What is FOIL and PEMDAS?

Answers

Answer 1

Answer: FOIL and PEMDAS are both ways to solve mathematical equations.

FOIL
First
Outside
Inside
Last

PEMDAS
Parenthesis
Exponents
Multiplication &
Division
Addition &
Subtraction

FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)

PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7

Whew, hope this helped :D

Answer 2

Answer: Foil - prevent from succeeding
Pemdas - It is a method used my mathematics students to remember operations

(HELP ME PLEASE!!!!!! IT HAS PICTURES!!!!!)The edge of each cube used to build this rectangular prism is 1/3 inch long. Which equation shows the volume of the prism, in cubic inches?|A|(9/3⋅6/3⋅6/3) in.^3 = 12 in.^3

|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3

|C|(3 1/3⋅2 1/3⋅3 1/3) in.^3=25 25/27 in.^3

|D|(3⋅2⋅3) in.^3=18 in.^3

Answers

Answer:

Option B

Step-by-step explanation:

step 1

Find the number of cubes in the prism

$(3)(2)(3)=18\ cubes$

step 2

Find the volume of one cube

The volume of one cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$b=(1)/(3)\ in$

substitute

$V=((1)/(3))^3$

$V=(1)/(27)\ in^3$

step 3

To find out the volume of the prism , multiply the volume of one cube by the number of cubes

$V=((1)/(27))18$

$V=(18)/(27)\ in^3$

simplify

$V=(2)/(3)\ in^3$

Answer:

|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3

Calculate the height of 385cm of water
inside a cylinder of diameter 7cm.

Answers

Answer:

Step-by-step explanation:

The volume formula for a cylinder is A = πr²h where A, r, and h are area, radius, and height respectively. The radius is 1/2 the diameter which is 7 / 2 = 3.5. We are solving for h so we can write:

385 = 22/7 * (3.5)² * h

385 = 38.5 * h

h = 10

Which equation could be used to find the number of days, d, in h hours?

Answers

there are a total of 24 hours in a day.
lets say for example we go through 12 hours.
that means we went through half a day.
we need an equation that if you plug in 12 into hours, you get 1/2.
You get that with equation B
