We Find the Area of circle with this formula:
A= πr^2
If we find the area of circle it will be:
A=3.14 x (4cm)^2=3.14 x 16cm^2=50.24cm^2
Now if we find the area of the rectangle it is:
A=3cm x 2cm=6cm^2
And finally, we have subtract the area of rectangle from the area of circle
A(shaded)=50.24cm^2 - 6cm^2= 44.24cm^2
I hope this helped! Good luck :)

Answer: 44.27

Step-by-step explanation:

area of a circle formula: A=πr^2

π4^2 = 50.26548, rounded 50.27

area of a rectangle: A = bh

3 x 2 = 6

subtract 50.27 - 6 = 44.27

A taxi service charges a $1.90 fee for each ride plus an additional $0.80 per mile. If a taxi ride costs $4.30, how many miles did the taxi travel during the ride?

Answers

3 miles as additional and one taxi ride

3 miles because you have to subtract the 1.90 from the total which gives you 2.4 and then you have to see how many times .80 goes into 2.4

Find the value of x. The diagram is not to scale.

Answers

Consider Z the third angle in the image;

105 + z = 180

z = 75

72 + x + z = 180

72 + 75 + x = 180

x = 33

Alternative D)

X=33. 105 shares a line and a line is equal to 180. 180-105= 75. Then add 75 +72= 147. Then 180-147=33. A triangle is 180 degrees

1) It’s true because -5 is way smaller than 3. All the negatives are below the 0 and everything below the 0 is lower than everything above the 0.

2) false. it’s false because in order -5 isn’t even close to 3

3) false.. It’s false because when you have those 2 line that are covering the -5 that means it’s “transforming” into a positive number. So therefore it’s would be 5>3 that would make it true.

4) True. it’s true because like I said the to lines mean the absolute value of something. So it’s being switch to a positive number

Hope this helps :)

Answer:

m=75

percentage= 32

part= 24

whole= 75

Step-by-step explanation:

To get m, you divide 18 by .24(since it's the decimal form of 24%) and you get 75.

The part/whole part I'm not exactly sure about but since it's 24% of 75, I'm guessing the part is 24 and the whole is 75 and that's the entire thing we are working with here.

To get the percentage, we use the 24/75 fraction. We have to get the demonator to 100 but since 75 can't be multiplied by anything to get to 100, we have to simplfy the fraction so the demonator can go into 100. I divided the fraction by 3 since that would get the fraction to 8/25. 25 can go into 100 if we multiply by 4 so that's what you do. The ending fraction would be 32/100 after multiplying the numerator and demonator by 4(8/24). So the percentage would be 32% or 32/100.

I have never done this is my life but it is similar to what I have done so please correct me if I am wrong. I hope this helped you and I am incredibly sorry if it is wrong.

For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?

Remember money is rounded to the nearest hundredth.

Answers

Answer:

44.03-2.75=41.28

Find out the total number of cookies

8+16=24

Then divide the total cookie price by the total number of cookies

41.28÷24=1.72

Each cookie costs $1.72

Arnoldo was drawing names for the door prizes at the school festival. He drew two names from the door prize box, and then awarded both winners a prize. Is this an example of an independent or dependent event?

A. independent event
B. dependent event
C. none of the above

Answers

It’s B or c but I think it’s c

The correct answer is Dependent event which is option B.

Which concept is used

Dependent events are affected by other occurrences. Independent occurrences have no bearing on one another and have no effect on the likelihood of another event occurring.

Check whether the situation is an independent or dependent event.

Here, Arnoldo was drawing names for the door prizes at the school festival and he drew two names from the door prize box and then awarded both winners a prize.

Since, there will be an increase or decrease in the chances of drawing another name from the door prize box.

Thus, we can tell that the given situation is an example of a dependent event as it affects one another.

So, the correct option is B i.e., Dependent event.
