If a car traveling at 50 km/h will skid 16 m when its brakes lock, how far will it skid if it is traveling at 120 km/h when its

brakes lock? (This question is typical on some driver's license exams.)

Would it be 38.25 because I did 120km/h ÷ 50km/h and got 2.4 then I multiplied it by 16 and got 38.4 as the answer.

I hope i helped.

What’s the distance between (4,-9) and (5,3)

laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

<u>Given information</u>

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

<u>Given formula</u>

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

<u>Substitute values into the formula</u>

$Distance = \sqrt{(5-4)^2+(3+9)^2}$

<u>Simplify values in the parentheses</u>

$Distance = \sqrt{(1)^2+(12)^2}$

<u>Simplify exponents</u>

$Distance = \sqrt{1+144}$

<u>Simplify by addition</u>

$Distance = \sqrt{145}$

Hope this helps!! :)

Help quick! i can't figure it out! <br> +6p - 3q + z - 3p + 2q - z - p + 00q

ki77a [65]

Answer:

2p + 99q

Step-by-step explanation:

To simplify the expression, combine the like terms. Like terms are terms which have the same variable. Assume 00q is 100q.

6p - 3q + z - 3p + 2q - z - p + 100q

6p - 3p - p = 2p

- 3q + 2q + 100q = 99q

z - z = 0

So the expression is 2p + 99q
