Answer:

C

Step-by-step explanation:

1) find the area of the square

A = side^2 = 14^2 = 196 cm^2

2) find the radius of the two semicircles

radius = side / 2 = 14 : 2 = 7 cm

3) find the areas of the two semicircles

A = radius^2 x 3,14 x 2 = 7^2 x 3,14 = 153.86 cm^2

4) find the area of the shaded region

196 - 153.86 = 42.14 cm^2

Answer:

C) 42.14 cm²

Step-by-step explanation:

<u>Recall the area formulas for a square and circle:</u>

Area of square: A=s²

Area of circle: A=πr²

<u>Given:</u>

π=3.14

s=14

r=s/2=14/2=7

Therefore, the area of the square is A=14²=196 cm²

The area of the two semicircles is A=3.14(7)²=3.14(49)=153.86 cm²

Find the difference between the two areas to get the shaded area:

196 - 153.86 = 42.14

Therefore, the shaded area is 42.14 cm², making C the correct choice.

Luke’s dad need 165 for a new suitcase. If he saves an equal amount for 3 weeks, how much does save each week?
goldenfox [79]
This is easy the answers 55 you just need to divide

165 ÷ 3 = ?

Step 1: Look at the multiplications of three can you make a group with an answer close to one? if not look at 16 and the multiplications of three is there a number close to 16 or exact?

Step 2: In this case 5 × 3 = 15, so 15 is close to 16.


Step 3: Now you need to subtract 16 and 15, 16 - 15 = 1.


Step 4: Like there's no number that has 1 as a answer, you need to lower the 5.


Step 5: Once you lower the five it makes 15 in the in the multiplications of three is there something close to 15 or exact? Yes there is a number that can make 15, it's 5 × 3 so 15 take away 15 makes zero so your answer will be simple, 55.

So Luke's dad needs to save $55 each week.

A book sold 39,300 copies in its first month of release. Suppose this represents 6.3% of the number of copies sold to date. How
konstantin123 [22]
Hi there! So 39,300 copies of a book were sold on debut month of release, and that represents 6.3% of all copies sold to date. To find the total amount of copies sold, we can write and solve a proportion. Set it up like this:

39,300/x = 6.3/100

We set it up like this because 39,300 is part of the total amount, and it represents 6.3% of the total book sales. Percents are parts of 100, which is why 6.3 is above 100. Let's cross multiply the values. 39,300 * 100 is 3,930,000. 6.3 * x is 6.3x. that makes 3,930,000 = 6.3x. Divide each side by 6.3 to isolate the x. 6.3x/6.3 cancels out. 3,930,000/6.3 is 623,809.5238 or 623,810 when rounded to the nearest whole number. There. The total amount of copies sold to date is about 623,810.

Answer:

3\frac{3}{4} , 4\frac{1}{4} , 4\frac{1}{2} (two x's on this spot), 5

Step-by-step explanation:

you need an x in each point (A, B, C, D, E) given in the chart

notice point B and E are the same

3\frac{3}{4} , 4\frac{1}{4} , 4\frac{1}{2} (two x's on this spot), 5

I believe the bottom left shows the right answer

The weekly incomes of a large group of executives are normally distributed with a mean of $2,000 and a standard deviation of $10
cestrela7 [59]

Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.

μ =2000, σ =100

We have to find z score for income $2100 i.e x=2100

Z = \frac{x-mean}{standard deviation}

= \frac{2100 - 2000}{100}

Z = 100/100

Z = 1

The z score for income $2100 is 1
