Answers

Answer: 160

Step-by-step explanation:

Answer: 160m3

Step-by-step explanation:

For the first prism, you find the volume by multiplying the length of the prism by the width of the prism by the height of the prism.

V = w h l = 8m x 3m x 2m = 48m3

For the second prism, you do the same thing you did to the first one.

V = w h l = 4m x 4m x 7m = 112m3

Lastly, you add the volume of both prisms to get your answer.

48m3 + 112m3 = 160m3

Area of rectangle: 6

Area of triangle: 4+3+1 = 8

8x7=56/2 =28

28-6=22

Answer: 22

Step-by-step explanation:

First, you want to find the area of the triangle with the formula 1/2 × b × h.

1/2 x 8 x 7 = 28

Next, you want to find the area of the smaller rectangle with the formula, b x h

3 x 2 = 6

Then, you subtract the two numbers

28 - 6 = 22

how can I use A as a different variable.
When differing from X, Y and K
And when having 2x3= A
Even when I know A is a negative number.

Answers

You can use A as a different variable by simply assigning a value to it, like any other variable

What is a variable?

A variable is a symbol used to denote a mathematical object in mathematics. Any number, vector, matrix, function, function argument, set, or set element can be represented by a variable.

An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable is, in other words, a symbol denoting a number whose value is unknown.

You can use A as a different variable by simply assigning a value to it, like any other variable. For example, you could write "A = -6" to assign the value of negative 6 to A. It's important to remember that A is now a distinct variable from X, Y, and K, and should be treated as such in your code or equations.

Susie mixed 6 cups of popcorn with 2 cups of pretzels. She then divided the snack into bags with cup in each. After dividing, how many bags of snack bags will Susie have?

WHO ANSWERS ASP AND CORRECT GETS A BRAINLIST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

8 bags of snacks

Step-by-step explanation:

After mixing each snack, there will be a total of 8 cups of snack mix.

6+2=8

With 8 cups of snack mix being divided, and having one cup of snack mix in each bag, there will be a total of 8 snack bags.

8 snack bags

If Susie mixed 6 and 2, it’ll become 8 cups in total of the snack mix. In each snack bag there’s 1 cup, so there would be 8 snack bags.
