Answer 1
[16] 1/4’s are in 4.
[5] 1/3’s are in 1 2/3
[3] 1/5’s are in 3/5.
Answer 2
2. 16
This is because if you do keep change flip you will have 4/1*4/1 by keeping the four and just changing it into an improper fraction. Changing the division sign into a multiplication sign and then flipping the 1/4 to 4/1. Than your will simplify 4/1*4/1 is 16/1. Than if you simply 16/1 you will get just 16.
3. 5
This is the same thing but you will make the 1 2/3 into an improper fraction and that is by multiplying the 1 by the denominator (3) and then adding by the numerator. Making you get 5/3 and then using keep change flip you will have 5/3*3/1 making 15/3. Than simplifying into just 5. This is because 15 divided by 3 is equal to three.
4. 3
Same thing just use keep change flip. Than you have 3/5*5/1 and that is equal to 15/5 making it 3.

Hope this can make it easier for you to understand :)

Step-by-step explanation:

A) The bus rental would be the total cost or "C". So 700=250+3m.

B) Solve with properties of equality:

  700 - 250 = 250 + 3m - 250

  450 = 3m

  450/3 = 3m/3

  150 = m

  150 miles

C) Check your answer by plugging the answer into the original equation:

  C = 250 + 3(150)

  C = 250 + 450

  C = 700

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.

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

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

which model shows 9 (3+6) = (9 x 3) + (9 x 6)?

NO LINKS OR FILES THANK YOU!!

Answers

Answer:

Look at the image.

Step-by-step explanation:

The required model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B. Option B is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

What is an array?

The array is a collection of things and shapes in a specific pattern.

Here,

Given that, to determine the model that represents 9 (3+6) = (9 x 3) + (9 x 6)

So 9 (3+6) = (9 x 3) + (9 x 6) represents the arrangement of squares in array form,

If in a pattern there are 9 rows there must be 3 and 6 columns or vice versa.,

So from the above definition, a model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B.
