Answer: 72

Step-by-step explanation:

From the question, we are informed that Mary Beth needs a 90% on her final exam to get an A for the quarter and that the exam has 80 questions.

The number of questions does that Mary need to answer correctly in order for her to get an A would be 90% of 80. This will be:

= 90% × 80

= 90/100 × 80

= 72

She must get 72 to get a A.

Answer:

B. 31.62

Step-by-step explanation:

First, find the distance of the line using the distance formula, [tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }[/tex]. Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.

Answer:

x = 11

Step-by-step explanation:

3(x-5) = 18

Step one: Distrubute 3 to the numbers in the parenthesis.

3x - 15 = 18

Step two: Add 15 on both sides

3x = 33

Step three: Divide by 3 on both sides

x = 11

Step-by-step explanation:

A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.

An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.

From the question:

KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)

From line segment addition postulate:

KV = KN + NV

substituting:

2x + 6 = 10 + x

2x + 6 - x = 10

x + 6 = 10

x = 10 - 6

x = 4

KV = 2x + 6

substituting x = 4:

KV = 2(4) + 6

KV = 14

Answer:

Step-by-step explanation:

In order to divide these fractions, you must turn the mixed number into a fraction like below:

1 1/2 = (2 x 1 + 1) / 2 = 3/2

In order to divide fractions, you must multiply by the reciprocal of the denominator. In this case, you are dividing (3/2) / (3/4) and 3/4 is the denominator.

3/2 * 4/3 = 12/6 = 2. Your answer is 2.

Answer:

the equation that has the same solution as the given expression is

m + 7.28 = 18.28

Step-by-step explanation:

Given expression;

0.2m = 2.20

To solve for m, divide both sides by 0.2

[tex]\frac{0.2 m}{0.2} = \frac{2.2}{0.2} \\\\m = 11[/tex]

From the given options, the equation that has the same solution as the given expression is m + 7.28 = 18.28

Solve the equation to confirm as follows;

m + 7.28 = 18.28

collect like terms

m = 18.28 - 7.28

m = 11

Answer:

$66.60

Step-by-step explanation:

Find out how much money Jerome earns from the 1.8% interest.

100% = 3700

1% = 3700 ÷ 100 = 37

1.8% = 37 x 1.8 = 66.60

(Final answer)

Answer:

Additional fee or hour = $8.5

y = $2 + 8.5x

Step-by-step explanation:

Given that :

Total paid = $36

Number of hours = 4

Initial rental fee = $2

Additional fee per hour = a

Total amount = initial rental fee + additional fee per hour * number of hours

36 = 2 + 4a

36 - 2 = 4a

34 = 4a

a = 8.5

Hourly fee = $8.5

Therefore, the cost formula

y = initial fee + regular fee * number of hours

y = $2 + 8.5x

Not completely sure, and I know its late but for the other people that look at this, 11.80$

Step-by-step explanation:

I found how many more letters Alexander had over Lucia, then when I got 4 divided it in-between 12.60 - 9.40 (3.20)  I got 0.8. knowing the letter cost i got the initial fee for the mug (5.40) and added 8x0.8 to it, resulting in my answer 11.80$

Penelope has to pay $11.8 for a mug with her own name on it.

Number of letters in Alexander's name = 9

Number of letters in Lucia's name =5

The Difference in the number of letters in both the names

= 9-5

=4 letters

Alexander pays =  $12.60

Lucia pays = $9.40

Difference in payments = 12.60-9.40 = $3.20

It means charge for 4 letters = $3.20

So, charge for 1 letter = $0.80

Number of letters in Penelope's name = 8

So, Penelope will pay = 8*0.80 +fixed fee for the mug

= $6.4 +fixed fee for the mug

The Fixed fee for the mug will be the payment done by Penelope for either Alexander or Lucia minus the charge for each word in the word Alexander or Lucia respectively.

The Fixed fee for the mug = $9.40 - charge for each word in the word "Lucia"

The Fixed fee for the mug = 9.40 - 5*0.80 = $5.40

So, Penelope will pay = 6.4 +5.4 =$11.8

Therefore, Penelope has to pay $11.8 for a mug with her own name on it.
