Michael's tennis serve is 105 mph. At the same rate, how many feet would his serve travel in one second to the nearest foot?

2 answers:

7 0

Since there are 60 seconds in an hour, we know to divide by 105 by 60, which gives us 1.75. Then we round 1.75 to 2.

Therefore, his serve will travel 2 miles per second.

7 0

Answer: 154

Step-by-step explanation: your answer should be smaller than the 105 miles. I know is 105 miles/ 1 hour so 105 miles to feet, then 1 to 60 seconds.

so 554400/ 60

then divide both by 60 to get your answer.

Joni earned $0.625 per day for two days as interest on her $1,000.00 investment. What percent interest did she earn in total? Gi

Kitty [74]

Joni’s total interest earned is 0.125% of her investment.

Solution:

Given that

Interest earned by Joni per day = $0.625

Investment done by Joni = $1000

Duration of earning interest = 2 days

Total interest earned = interest earned by Joni $\times$ duration of interest earned.

= 0.625 $\times$ 2 = $1.25

$\text { Percentage of interest earned }=\frac{\text {total interest earned}}{\text {investment done}} \times 100$

$=\frac{125}{1000} \times 100=0.125 \%$

So Joni’s total interest earned is 0.125% of her investment.

If the median of five consecutive even integers is 20, what is the value of the smallest integer?

IceJOKER [234]

Answer:

Step-by-step explanation:

Median means the middle number. So you can look at it like this:

a,b, 20, c,d

Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.

This should be your answer:

16, 18, 20, 22, 24

Consecutive, and even.

How do I solve this problem? With steps please. 6x/3-2x/3+8/3=8

Elza [17]

So the left side has a common denominator of 3. The 6x, -2x, and 8 can all go over a single 3. (6x-2x+8/3). Simplify the x's to get 4x. Now both sides have to be multiplied by 3 to get rid of that fraction. Then you just have 4x+8=24. Subtract 8 from both sides to get the x's alone, then divide both sides by 4 to get x alone. I have a picture to help.

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?

SashulF [63]

Step-by-step explanation:

assuming the first part is -1/8th, you would want to first add 1/8, to attempt to isolate the x. you now have x+35 = -6 7/8. add 35, and you get x= 28 1/8
