Answer:

Additions.

Step-by-step explanation:

Multiplication is equivalent to repeated additions and is faster, especially if the numbers are large.

A simple example is 2 * 3 = 2 + 2 + 2.

Answer:

Addition.

Step-by-step explanation:

Multiplication is a faster way to do repeated addition.

For example, lets say you would add 10 fifteen's together. Addition would make it:

15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15

= 30 + 30 + 30 + 30 + 30

= 60 + 60 + 30

= 120 + 30

= 150

However, when multiplying:

15 x 10 = 150

As you can tell, multiplication makes it so there are less steps, and is less time consuming.

Step-by-step explanation:

Use geometric formulas to solve for each individual SIDE of the triangular prism

TOP and BOTTOM TRIANGLE sides:

$\frac{ab}{2}$
$\frac{6(8)}{2}$ <--- times 2 because we have TWO identical triangle sides

RIGHT RECTANGULAR side from our perpsective:

LxW
8(7)

FRONT RECTANGULAR side:

LxW
7(6)

BACK RECTANGULAR side:

LxW
7(10)

Now you add all of those formulas together for your answer.

$\frac{6(8)}{2}$ + $\frac{6(8)}{2}$ + 8(7) + 7(10) + 7(6)

= 216

P is inversely proportional to Q.

$If\ P\ is\ inversely\ proportional\ to\ Q\ then:\\\\P\times Q=constans\\\\P=100;\ Q=32\\\\100\times32=3200\\\\P=2Q\\\\therefore\\\\P\times Q=2Q\times Q=2Q^2\\\\2Q^2=3200\ \ \ \ |divide\ both\ sides\ by\ 2\\Q^2=1600\ \ \ \ \ |sqare\ rot\ both\ sides\\Q=\sqrt{1600}\\\boxed{Q=40}$

The perimeter of a rectangular toddler play area is 100 feet. The length is 10 feet more than 3 times the width. Find the length

Mekhanik [1.2K]

Answer:

length and width = 40 and 10 ft.

Step-by-step explanation:

The perimeter of a rectangular toddler play area is 100 feet.

Perimeter = 2(length + width)

Let the width = w

The length is 10 feet more than 3 times the width. Length = 10+(3w)

now put the values

100 = 2(10+3w + w)

100 = 2w + 20 + 6w

100 = (2w + 6w) + 20

100 = 8w + 20

8w = 100 - 20

w = $\frac{80}{8}$

w = 10 feet.

Now Length = 10+ (3w)

= 10+( 3 × 10)

= 10 + 30

= 40 feet

Therefore, length = 40 feet and width = 10 feet
