Answer:

Step-by-step explanation:

To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you  don’t have to worry about the x because it is a variable so now add  -4 +2. but first we have to turn negative into positive so you add -4 + 8

How much interest will she earn in 3 years?
alekssr [168]
For this, the equation is 
90× 1.13³=y
X was replaced with y. Since she is gaining, you have to remember she is going to have 100 percent of what he had before, she will not lose any.
90× 1.13= 129.86
Now, we need to find the amount of interest she gained, so we have to subtract 90 from the total.
129.86-90=39.86
We can also find the answer by completing a small chart.
The first column will be the year. The second will be the amount. The third will be the interest for the year.
1                                                90                                                11.7
2                                                101.7                                           13.22
3                                                 114.92                                        14.94
The total would round to 39.86, so her interest for the 3 year would be 39.86, with her having 129.86 altogether.

Find the length of the base of a square pyramid if the volume is 128 cubic inches and has a height of 6 inches
Len [333]

Answer: a = 8

Step-by-step explanation:

Volume of a square based pyramid is given as

\frac{a^{2}h }{3} .

where a is the length of the side and h is the height.

Substituting into the formula , we have

V = \frac{a^{2}h }{3}

128 = a^{2}h /3

384= a^{2} X 6

Divide through by 6

384/6 = a^{2}

64 = a^{2}

Therefore :

a = \sqrt{\frac{64}{1} }

a = 8

A car travels at a speed of 85 miles per hour. How far will it travel in 15 mins?
marusya05 [52]

In this question, we're trying to find how many miles a car travels in 15 minutes.

We know that the car travels at 85 mph.

However, we need to know how many miles it travels per minute.

To find this, we would divide 85 by 60.

85 ÷ 60 = 1.4166

The car drives at a speed of about 1.42 per minute.

We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.

1.42 · 15 = 21.3

The car travels at a approximately 21.3 miles in 15 minutes.
