A pair of 120 shoes was discounted 20 percent a costumer had a coupon for an additional 5 off what was the final price of the sh
STatiana [176]

Answer:

The final price of the shoes is $91.20.  

Step-by-step explanation:

In order to find the final price of the shoes, we need to calculate each discount separately.  Since the initial cost of the shoes is $120, we need to first find the cost after the 20% discount.  If the shoes are discounted 20%, then we can find the cost by multiplying the original amount by 80%, or 0.8:  $120 x 0.80 = $96.00.  Since the customer also has an additional 5% off with the coupon, we can then take the new total, $96.00, and multiply by 95%, or 0.95, to get the final cost:  $96.00 x 0.95 = $91.20.

pickupchik [31]
16x-4x=-48   1. first we combine like terms by subtracting 4 from 16
12x=-48       2. now, we divide both sides by 12 to isolate x
 x=-4

The interior angles of a triangle have measures kº, 27°, and 10°<br> What is the value of k?
S_A_V [24]

Answer:

k = 143

Step-by-step explanation:

The sum of the 3 interior angles of a triangle = 180°, thus

k = 180 - (27 + 10) = 180 - 37 = 143

Answer the 3 question with the Task card Thank you.
REY [17]

Answer:

Please see below.

Step-by-step explanation:

I will be using * to express multiplication, and ^ to express squares.

A) Can you find the area of the shape?

Yes, we can.

We can simply multiply 5x - 3 by 2x, as seen below.

(2x)(5x - 3)

2x * 5x = 10x^2

2x * -3 = -6x

Area = 10x^2 - 6x

B) Can you find the perimeter of the shape?

Yes.

Because a rectangle has two sets of equal sides, we can merely multiply the two given measurements by two and add them together to find the perimeter.

2x * 2 = 4x

2(5x - 3) = 10x - 6

4x + 10x - 6 = 14x - 6

Perimeter = 14x - 6

C) If x = 2, what is the area of the shape?

We can just plug in 2 wherever our x shows up.

5x - 3 = 5 * 2 - 3 = 10 - 3 = 7

2x = 2 * 2 = 4

7 x 4 = 28

We can also use our previous formula from A.

10x^2 - 6x

10 * 2^2 - 6 * 2

10 * 4 - 12

40 - 12

28

Our area if 28 if x = 2

Please let me know if any of these are incorrect.

If Aldo puts 400 into a savings account that paid an interest rate of 5.4 percent What was the total amount in his account at th
Ne4ueva [31]

Answer:

\$421.60

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=1\ year\\ P=\$400\\ A=?\\r=5.4\%=5.4/100=0.054

substitute in the formula above

A=400(1+0.054*1)

A=400(1.054)

A=\$421.60

Remember that Interest is equal to

I=A-P

I=\$421.60-\$400=\$21.60
