Alex Rode her skateboard her velocity changed from 3m/s to 1m/s in 4 seconds. What was her acceleration?

1 answer:

7 0

You can use the acceleration formula:

$a = \frac{\Delta v}{\Delta t}$
$a = \frac{1 - 3 }{4 - 0}$
$a = \frac{-2 }{4}$
$a = -\frac{1 }{2} = -0.5$

How do you figure out whether a fraction will be a terminating decimal or a repeating decimal?

If<span> the prime factorization of the denominator of a fraction has only factors of 2 and factors of 5, then it can be written as something over a power of ten. This means that the decimal will terminate.</span>

Find the missing side of this right

navik [9.2K]

Answer:

x = 13

Step-by-step explanation:

First start with the blank equation

$a^{2} + b^{2} = c^{2}$

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

$5^{2} + 12^{2} = c^{2}$

Then solve

25 + 144 = $c^{2}$

169 = $c^{2}$

$\sqrt{169} = \sqrt{c^{2} }$

c = 13

4) Choose the correct inequality for this situation.

Ksenya-84 [330]

Answer:

B. 21x + 40 ≤ 124

Step-by-step Explanation:

Maximum amount budgeted = $124 (this means they can't spend more than this)

x = number of people

Cost per head = $21

Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:

21x + 40 ≤ 124

(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).
