Answer:

49, 35, 32

Step-by-step explanation:

A prime number is a number whose factors are 1 and itself

Eg 7

7 is a prime number because it only comes in table one and 7

Or it’s only factors are 1 and itself

A composite number comes in 1, itself and other tables

Eg. 16

It comes in table 1, 2, 4 and 16

Are x = -4 and x = 6 solutions to 5x + 7 < 22?<br> TRUE OR FALSE

DochEvi [55]

Answer:

x=-4 is true, x=6 is not

Step-by-step explanation:

5x + 7 < 22

Plug in our X values

5(-4) + 7 < 22 ?

solve

-20 + 7 < 22

-13 < 22 ?

x=-4 is true.

Repeat steps from ^

5(6) + 7 < 22

30 + 7 < 22

37 < 22 ?

x=6 is not true.

Hope this helped

A company made a profit of $75,000 over a period of 6 years on an initial investment of $15,000. What is its annualized ROI?

miv72 [106K]

The formula in getting the ROI or the Return on Investment is ROI = Net Profit/ Total Investment x 100. Below is the solution:

ROI = $ 75,000/$1500 x 100
ROI = $ 5 x 100
ROI = $ 500

You will then divide the $ 500 by 6 to get the ROI per year which is equals to $83.33

This figure consist of a rectangle a semi circle and a quarter circle what is the perimeter of this figure use 3.14 for pi

alexandr402 [8]

Answer:

37.55 m

Step-by-step explanation:

To find the perimeter, we have to add the lengths of each part of the figure.

We start from the circle on top. We see that its diameter is 10 m, therefore its radius is

r = 5 m

(because the radius is half the diameter). The perimeter of a circle is given by

$p=2 \pi r$

However, here we have half a circle, so its perimeter is

$p_1 = \pi r=(3.14)(5)=15.7 m$

Then continuing in a clockwise direction, we have to add the length of the side of 2 m:

$p_2 = 2 m$

Then we have two sides of a square of side 5 m, so:

$p_3 = 5 m + 5 m= 10 m$

Then we have a quarter of a circle of radius r = 5 m, so its perimeter is:

$p_4 = \frac{\pi r}{2}=\frac{\pi (5)}{2}=7.85 m$

Finally, we have one more side of length 2 m:

$p_5 = 2m$

Therefore, the total perimeter is:

$p=p_1+p_2+p_3+p_4+p_5=15.7+2+10+7.85+2=37.55 m$

Mick paid 2.94 in sales tax on an item that costs 42 dollars before tax. At that rate how much would he pay in sales tax for an

djverab [1.8K]

Mick would pay $4.06 in sales tax for an item that costs $58.00.

This can be found by working backwards in the problem. By dividing that sales tax paid (2.94) by the dollars before tax (42), you get a percentage that should equal the percentage of the total paid for tax.

2.94 ÷ 42 = 0.07

This means that the sales tax is 7% of the total prior to tax. So we'd then multiply our dollars (58) with the sales tax in decimal form (0.07)

58.00 × 0.07 = 4.06

Hope I could help!
