Counted a total of 40 white cars and yellow cars there were 9 times as many as white cars as yellow cars. how many white cars di

Law Incorporation [45]

Let W = number of white cars, and Y = number of yellow cars.
There were 9 times as many white cars as yellow cars. This means that the number of white cars was 9 times more than the number of yellow cars. This can be translated by the expression:
9Y = W
The person counted 40 cars in total:
W + Y = 40

So we get the system:
$\left \{ {{W+Y=40} \atop {9Y=W}} \right.$

In the first equation, we multiply by 9:
9W + 9Y = 360
In the second equation:
9Y= W
W-9Y = 0

Then we add the first with the second equation:
9W + 9Y + W - 9Y = 360
10 W = 360
W = 36

So He counted 36 white cars.

Hope this Helps! :)

Write the solution to the inequality in set - builder notation:<br> 5r + 8 < 63

Leni [432]

<span>First, the inequality needs to be solved. The first step is to subtract 8 from both sides of the inequality, leading to 5r < 55. Dividing 5 out from both sides, this will leave r < 11. Next, to form a set notation, the inequality is written in such form: {r | r < 11}.</span>

Veseljchak [2.6K]

Answer:

D. 267.9 in3

Step-by-step explanation:

So we know the diameter is 16 inches.

So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4

Now we need to find the volume.

V= 4/3 times 3.14 times 4^3= 268.08

So we would need to round which would give us 267.9 in3.

Therefore the answer is the D. 267.9 in3.

I hope this helps!!!

pychu [463]

The amount given to charity from Kendall’s profit is $168.0146

Given:

Kendall’s profit = $1292.42
Percentage given to charity = 13%

<h3>How to find percentage</h3>

Amount given to charity = Percentage given to charity × Kendall’s profit

= 13% of $1292.42
