The ratio would be C=16/20

konstantin123 [22]3 years ago

4 0

Equivalent ratios are created by multiplying both numbers in the ratio by the same value. In the first ratio, 15 = 5 x 3, but 10 ≠ 4 x 3, so it's not equivalent to 4:5. In 4/10, 4 = 4 x 1, but 10 = 5 x 2, so again, the two aren't equivalent.

In 16/20, though, we find that 16 = 4 x 4 and 20 = 5 x 4. Since both the 4 and the 5 are being scaled up by the same factor, 16/20 is equivalent to 4:5.

Find the distance between the points ( – 9, – 4) and ( – 4,8).

Dmitriy789 [7]

Answer:

$Distance=13\ units$

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two pints $(x_1,y_1)\ and\ (x_2,y_2)$ is given by

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between $(-9,-4)\ and\ (-4,8).$

$d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13$

How do you do inverse operation on a fraction ( y/3 ) = -6

NemiM [27]

$\frac{-1}{18}$

Solution:

Given expression is $\frac{y}{3}=-6$

To find the inverse of y.

⇒ $\frac{y}{3}=-6$

Do cross multiplication.

⇒ y = –6 × 3

⇒ y = –18

Inverse of y means reverse the function.

We know that inverse of y is $\frac{1}{y}$ .

⇒ $\frac{1}{y}= \frac{-1}{18}$

Hence, inverse of y is $\frac{-1}{18}.$

Shaila and her sister Sarah are babysitting three Kids for 5 hours. If the parents pay $2.50 per hour for each kid,how much will

mart [117]

3 times 5 times 2.5 = $37.5

3 x 5 =15

15 x 2.5 =37.5

37.5 x 2 = 75 for both of them

I don't know if this is right or not, but that's how I would solve it!
