Part A.Maggie is making a necklace using 14 inch string and identical beads. Maggie has placed 12 beads next to each other starting at the left end of the string as shown in the figure. The 12 beads fill 3 inches of the string. How many total beads will completely fill the 13 inch string?
Part.BAfter filling the string from end to end, Maggie decides to leave one inch at each end of the string with no beads. How many beads does she need to remove from the beads she used to completely fill the string?

Answers

Part a: 52 beads I think
12/3=4
4*13=52

Part b: 8 beads
Every inch is 4 beads.
4*2=8

Answer:

a)  56 beads

b)  8 beads

Step-by-step explanation:

12 beads take 3 inches so yes 12/3 =4 per inch

but then the necklace is 14 in long so 4 *14=56 beads

if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads

If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?

Answers

She is speeding

First you need to converted miles into km as she was driving with miles but our speed limit is km so to maintain the balance we have to convert the measurements into one unit

Speed limit was 80km
She was driving 75 miles
We know,
1 mile = 1.609 km
So 75 * 1.609 = 120.675 km

So speeding = (120.675 - 80)
= 40.675

Therefore, she was over 40 km speed limit

Answer:864m^2

Step-by-step explanation:

18*18=324

18*30=540

540+324=864

Answer:

684 m.

Step-by-step explanation:

First you divide the shape into one rectangle and one square. You first multiply 18 x 18 for the square to find the area, which equals to 324. Then you do 18 x 30, as the sides are equal. this equals to 540. Now, you add up 324 and 540. You will get the total of 684.

9=3/2x step by step ASAP

Answers

Answer <3

Hello there! I'm here to help with your question!

I believe the answer is x= 6

The explanation:

9 = [tex]\frac{3}{2}[/tex] x

9 =[tex]\frac{3x}{2}[/tex]

9 = [tex]\frac{3x}{2}[/tex]

2 · 9 = · [tex]\frac{3x}{2}[/tex]

2 · 9 = 2 · [tex]\frac{3x}{2}[/tex]

2 · 9 = 3x

x = 6

I NEED HELP FAST ITS FOR A TEST (no links pls)
Part A: Explain why x = 6 makes 5x − 6 ≤ 24 true but not 5x − 6 < 24. (5 points)

Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.

Answers

Answer:

I dont know about A but the answer for B is below

Step-by-step explanation:

6x + 4 = 34 = (6x5) + 4 = 34

Answer:

Seem you are doing the same test I did! Module 7 part 2?

Anyway!

Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6  = 24.

Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.

And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.

Part B:

6x + 4 = 34

6x5 = 30

30+4=34

To verify: (6*5) + 4 = 34. The answer is five.

Bradley has a coupon for 15% off the price of a computer. The sales tax is 8%.
How much money did Bradley save, including sales tax, by using his coupon?
(Total cost of the computer with sales tax and coupon is $454.41)

Answers

Answer: $31.81

Step-by-step explanation:

First figure out how much the sales tax was

454.41x0.8=36.35

Then figure out how much the coupon subtracted off the total price

454.41x0.15=68.16

Subtract 68.16 by 36.35

68.16-36.35=31.81

7. Terrance needs to find the lateral surface area of the box shown below. Assuming that the base is the bottom of the prism, which of the expressions below will give him the correct lateral surface area?

Answers

The expression that will give the correct lateral surface area of the rectangular prism = (14.5 + 14.5 + 7 + 7)(8.6)

What is the Lateral Surface Area of a Rectangular Prism?

The lateral surface area (LSA) = 2(l + w)h

Given the following:

l = 14.5 w = 7h = 8.6

Lateral surface area of the prism = 2(l + w)h = 2(14.5 + 7)8.6

Lateral surface area of the prism = (14.5 + 14.5 + 7 + 7)(8.6)

Answers

Answer:

Yes, Clare's score on the test is the median.

Step-by-step explanation: Yes, because if we line up the scores from least to greatest and continue to cross off a score on each side, Clare's score will be exactly in the middle.

Yes clare’s test score is the median. This is true because the median is the middle of the data so if there are equal numbers of 12 below and above her score that would mean her score is in the middle and would be considered the median
