Answer

4480

Step-by-step explanation:

to find the area you take all the sides and multiply them together.

10 x 8 x 7 x 8 = 4480

Answer:

Question 1: 34.56 mm

Question 2: 12.57 in

Question 3: 15.70 yd

Step-by-step explanation:

Answer:

10. 91.08mm

11. 33.12in

12. 41.4yd

Step-by-step explanation:

To find the answer to each, we first need to calculate the circumference:

(use 3.14 for π)

(2 * Diameter) * π = Circumference

Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.

(Circumference / 2) + Diameter

Do this for each semi-circle as shown here:

10. (2 * 22) * 3.14 = 138.16

(138.16 / 2) + 22 = 91.08

11. (radius is given so double the middle)

(2 * (2 * 4)) * 3.14 = 50.24

(50.24 / 2) + 16 = 33.12

12. (2 * 10) * 3.14 = 62.8

(62.8 / 2) + 10 = 41.4

Answer: Andre is ordering ribbon to make decorations for a school event. He needs a total of exactly 50.25 meters of blue and green ribbon. Andre needs 50% more blue ribbon than green ribbon for the basic design, plus an extra 6.5 meters of blue ribbon for accents. How much blue ribbon does Andre need to order?

Andre needs exactly 32.75 m of blue ribbons and 17.5 m of green ribbons.

Step-by-step explanation:

Andre requires exactly 50.25 m of blue and green ribbons. It is given in the question that there has to be 50% more blue ribbon than green ribbon, plus an extra 6.5 meters of blue ribbon for accents.

Answer:

32.75 m of blue ribbons and 17.5 m of green ribbons..........

Answer:

A

Step-by-step explanation:

Through process of elimination, no other answer is correct.

Answer:

well you find. out how many all of them measure. and add them and then that answer multiply of the main number

Step-by-step explanation:

first add up all of the lengths and then find that answer multiply it to the main number and then you will get your anwer it's a 2 step problem

Answer:

y=-38

Step-by-step explanation:

Undo the things that are being done to the variable.

1: Multiply both sides by nine to undo division.

-45=y-7

2: Add 7 to both side to undo the subtraction.

-38=y

Thats your answer!

Answer:

the answer should be -38 which is option c.

Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be  -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.

Answer:

Average change = Total change / 4 days

= (7/8) / 4

= 7/32. (C)

Step-by-step explanation:

Average change = Total change / 4 days

Total change = (-1/8) + (3/4) + (3/4) + (-1/2) = 7/8.

I will only be writing the reasons for each and you can respond if you need clarification for anything:

1. given

2. opposite sides of a parallelogram are congruent (and a rectangle is a parallelogram so the properties apply)

3. def rectangle

4. SAS (side angle side congruence theorem)

5. CPCTC (congruent parts of congruent triangles are congruent)

braililest pls

Answer:

the answers should be a, e and c because they can be answer by collecting data multiple times.

Step-by-step explanation: Hope this answer helps :DDDDDDD and bye folks.

Answer:

the answer should be c) 15 and hope this is the right answer

Step-by-step explanation: You divide 210 by 14 and you will get 15 which is the answer so this is the correct answer.

Answer:

C

Step-by-step explanation:

[tex]210 \div 14 = 15[/tex]

Answer:

OPTION B

B. [tex]\frac{47}{120} ; \frac{1}{6}[/tex]

Step-by-step explanation:

A number cube is rolled 120 times; The number 4 comes up 47 times.

First, we have to determine the experimental probability of rolling a 4.

The formula to evaluate probability of an event is given; Probability = [tex]favorable outcomes/totaloutcomes[/tex]

Probability of rolling a 4; the total number of times when 4 appears/the total number of times number cube rolled= [tex]\frac{47}{120}[/tex]

We have to find the theoretical probability of rolling a 4.

Total number of outcomes number cube; 1,2,3,4,5,6

Probability of rolling a 4; [tex]\frac{1}{4}[/tex]

OPTION B IS CORRECT

Answer:

N=1

Step-by-step explanation:

If N = 1 then  4(1)= 4 whitch is less than 11

But if you plug in any other number

4(4) = 16

4(9) = 36

4(11) = 44

you can see that all of these are greater than 11, but we need something that is less than which would be N=1

Answer:

#7 = 53.41

#8 = 18.85

#9 = 87. 96

Step-by-step explanation:

The formula for Circumfrance of a circle is: C=2 π r

So lets do #7:

17/2 (the radius is 1/2 of the diameter)

R= 8.5 (now plug in)

C= 2 π 8.5

C=17π

Now repeat on 8 and 9

8:

C= 2 π 3

C=6π

c= 18.85

9:

C= 2 π 14

C= 28π

C= 87.96

30/(x+3)

it doesn't matter the order of the numbers for addition so the numbers in the parenthesis don't really matter which order they are in.

Answer:

-120-x

Step-by-step explanation:

Given:

[tex]\displaystyle \large{|120+x| \quad (x < -120)}[/tex]

This is the same as previous one. Recall modulus property:

[tex]\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}[/tex]

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x

Answer:

Slope: 5/4

Step-by-step explanation:

Answer:

the slope would be 5/4

Step-by-step explanation:

when you count from point (0,-3) where the line perfectly intersects that point, to point (4,2) where it does the same, you end up having to go up 5 lines, and over 4 lines giving you your slope that goes movement on the y-axis over movement on the x-axis or y/x, and you calculate this without diagonals, and you jump before you walk in this case instead of walking before you jump. I do not know what it means by draw a line representing the line, so im sorry on that part.
