A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particu

JulsSmile [24]

Answer:

<em>Answer: A'Reana's weekly allowance is $100</em>

Step-by-step explanation:

<u>Backward Solution</u>

To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.

The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.

That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45

This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.

Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100

Answer: A'Reana's weekly allowance is $100

We have a right triangle that has am 8 meter and 21 meter leg .Find the hypotenuse

Serjik [45]

Answer:

hypotenuse is 22.47 m

Step-by-step explanation:

The length of both legs of a right angle triangle are 8m and 21 m

We need to find the hypotenuse

To find hypotenuse we use Pythagorean theorem

Hypotenuse is AC and other two legs are AB and BC

$AC^2 = AB^2 + BC^2$

Hypotenuse ^2 = 8^2 + 21^2

hypotenuse = $\sqrt{8^2 + 21^2}$

= $\sqrt{64 + 441}$

= $\sqrt{505}$

= 22.47

So the length of the hypotenuse is 22.47 m

Which mathematical expression is equivalent to the number sentence below

alexandr1967 [171]

Solution :

It says multiply 8 by 12 and then add 9

reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .

Let us first write multiplying 8 and 12 which makes it 8 x 12

the result is being add to 12 so we place 8x12 in parenthesis then add 12

which , makes it : ( 8x12) + 9

this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .

we can write it without parenthesis like : 8x12 +9

Answer is third option .

9x-5y=29 find the value of y when x equals 1

svp [43]

9x - 5y = 29....when x = 1
9(1) - 5y = 29
9 - 5y = 29
-5y = 29 - 9
-5y = 20
y = 20/-5
y = -4 <==

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by

creativ13 [48]

The average rate of change of h over the interval is -48 feet per second.

Given,

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by

h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.

We need to find the average rate of change of h over the interval [3, 6].

<h3>How do we find the average rate of change of a function over an interval?</h3>

If we have an interval [a, b] and a function f(x).

The rate of change is given by:

= f(b) - f(a) / b - a

We have,

h(t) = −16t² + 96t and [3, 6].

h(6) = -16 x 6² + 96 x 6 = -576 + 576 = 0

h(3) = -16 x 3² + 96 x 3 = -144 + 288 = 144

The average rate of change of h is:

= h(6) - h(3) / 6 - 3

= 0 - 144 / 3

= -144 / 3

= -48

Thus the average rate of change of h over the interval is -48 feet per second.
