Answer:

A. 44

Step-by-step explanation:

The area of a trapezoid is $\frac{b_1+b_2}{2} * h$ , where b_1 and b_2 are the top and bottom bases, and h = height. We are given the bases as 8 and 14, and the height as 4.

$\frac{8+14}{2} *4$
$\frac{22}{2} *4$
$11*4$
$44$

Therefore, the answer is A. 44.

milton opens a store credit card when he purchases appliances for his kitchen. the interest rate is 17.45%. he charges $3,740 to

kari74 [83]

Answer-

The total cost of his purchase will be $3,846.34

Solution-

Here, the annual interest rate is 17.45%.

So monthly interest rate will be,

$=\frac{17.45}{12} =1.454\%=0.01454$

With a purchase of $3,740, the amount will be after one month,

$=3740(1+0.01454)^1=3740(1.01454)=3794.38$

Then she makes a payment of $1350, so the balance at the end of month 1 is

$=3794.38-1350=2444.37$

Now she has to pay with $2444.37 as principal amount, the amount will be after one month,

$=2444.37(1+0.01454)^1=2444.37(1.01454)=2479.91$

Then she again makes a payment of $1350, so the balance at the end of month 2 is

$=2479.91-1350=1129.91$

Final month, she has to pay with $1129.91 as principal amount, the amount will be,

$=1129.91(1+0.01454)^1=1129.91(1.01454)=1146.34$

So the total cost, including interest, would be the sum of the three payments,

$=1350+1350+1146.34=3,846.34$

A standard triathlon consists of a 0.93-mile swim, a 25-mile bike ride, and a 6.2-mile run. Skylar has already completed the swi

Fofino [41]

Answer:

about 4hours and 45 minutes

Step-by-step explanation:

> Standard triathlon

0.93-mile swim, and 25-mile bike ride in 3.5 hours

6.2-mile run in ? hours

> If it takes (12-minute/ 1mile) then will have (? minutes/ 6.2 miles.)

So we need to find an equivalent fraction of 12/1 that has x/6.2.

(12min/ 1 mile) = (x minutes/ 6.2 miles) , cross multiply

1*x = 12*6.2

x = 74.4 minutes will take to run 6.2 miles

> The rest of the ride times are given in hours so will convert or minutes to hours

60 minutes = 1 hours

74.4 minutes = x hours

x= 74.4 *1/ 60 = 1.24 hours

x = 1.24 hours will take to run 6.2 miles

> Approximately how long will it take her to complete the triathlon?

0.93-mile swim, and 25-mile bike ride in 3.5 hours

6.2-mile run in 1.24 hours

3.5 +1.24 = 4.74 hours which is about 4hours and 45 minutes

What is the value of x? 6(−3−x)−2x=14 Enter your answer in the box.

olchik [2.2K]

For this we would first simplify using order of operations.
6(-3-x) - 2x = 14 ------> Distribute
-18 -6x - 2x = 14 ------> Combine Like Terms
-8x - 18 = 14 Now we want to isolate x!
-8x - 18 = 14 ------> Add 18 to both sides.
-8x = 32 ------> Divide both sides by -8.
x = -4
Hope this helps!

There are 26.2 miles in a marathon.Enter the number of miles using a mixed number in simplest form.

KIM [24]

Let's look where the 2 is. The 2 is in the tenths place. When turning the tenths place into a fraction, it is x/10, being the digit in the tenths place. So, it would be 2/10.

We need to simplify the fraction. Let's divide the top and bottom by 2.

1/5 would be the simpplified fraction. Let's add the whole number.

So, the marathon is 26 1/5 miles.
