Able, Ben and Cal each played a game able’s score was six times ben’s score, Cale score was a hird time of Able’s score write do

Deffense [45]

Answer:

6:1:2

Step-by-step explanation:

Let a = Able's score, b = Ben's score, and c = Cal's score.

Since

Able's score was 6 times Ben's score, that means a = 6b.

Cal's score was a third of Able's score, so that means c = a/3. And since a = 6b, that means c = 6b / 3 = 2b.

Thus, the ratio of Able's score to Ben's score to Cal's score, a:b:c, is 6:1:2, because c is twice as much as b and a is 6 times as much as b.

Suzanne has a rectangular garden which is 18 feet long and 11 feet wide. She has 168 square foot of paving stones, and she wants

VikaD [51]

Answer:

width = 2.5 feet

Step-by-step explanation:

Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.

Area of the garden = length times width = 18 times 11= 198 square foot

Let 'w' be the width of the border

Length of the garden with border = 18+2w

Width of the garden with border = 11+2w

Area of the garden with border = $(18+2w)(11+2w)=4w^2+58w+198$

Area of the border = $4w^2+58w+198-198=4w^2+58w$

She has 168 square foot of paving stones,

$4w^2+58w=168$

Solve for w

apply quadratic formula

a= 4, b= 58 and c=-168

$\quad x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$w=\frac{-58+-\sqrt{58^2-4\cdot \:4\left(-168\right)}}{2\cdot \:4}$

$w=\frac{-58+-\sqrt{6052}}{8}$

we get two values for w

$w=\frac{-58+\sqrt{6052}}{8}=2.47$

$w=\frac{-58-\sqrt{6052}}{8}=-16.97$

A trapezoid has an area of 184 in^2. The height is 8 in and the length of one base is 16 in. Write and solve an equation to find

inna [77]

Answer:

The length of other base is 30 in.

Step-by-step explanation:

Given:

A trapezoid has an area of 184 in^2. The height is 8 in and the length of one base is 16 in.

Now, to get the length of other base.

Let the length of other base be $(b).$

Area of trapezoid $(Area)$ = 184 in².

Height of trapezoid ( $h$ ) = 8 in.

Length of one base (a) = 16 in.

Now, to get the length of other base of trapezoid we solve an equation:

$Area=\frac{(a+b)}{2} h$

$184=\frac{(16+b)}{2}\times 8$

$184=(16+b)\times 4$

$184=64+4b$

Subtracting both sides by 64 we get:

$120=4b$

Dividing both sides by 4 we get:

$30=b\\\\b=30\ in.$

Therefore, the length of other base is 30 in.
