Answer:

Step-by-step explanation:

multiply 1×2×1×2×3×5

Answer 2

Answer:

Step-by-step explanation:

Yellow block closest side and farthest side: 2x1=2 2x2=4

Yellow block right and left side: 1x1=1 1x2=2

Yellow block bottom: 2x1=2

Yellow block top: 2x1=2

Purple block closest side and farthest side: 5x2=10 10x2=20

Purple block right and left side: 2x3=6 6x2=12

Purple block bottom: 5x3=15

Purple block top: 5x3=15 15-2=13

2+2+2+1+1+13+10+10+6+6+15= 68

The overlap effects the calculation of the surface area because the bottom of the yellow block and a part of the purple block overlaps making it so that you would count it two times instead of the area that is visible.

I like to think of it as spray painting the blocks and seeing where the paint sprays.

Answers

Answer:

Neither A not B. It's C

Step-by-step explanation:

You'll have to visualize it.

Think about this as a cake on a table.

You want to eat the top — so you slice across horizontally.

When you have just the bottom left on the table, you will have a rectangle shape

Another hint is that the question says a "right rectangular pyramid". So no matter how you slice a pyramid, the bottom of each slice will look the same as the name. In this case "rectangular"

PS: I've attached a sketch of what it looks like before & after slicing.

At a garage sale, a large bin full of DVDs and CDs are being sold. All the DVDs are the same price, and all the CDs are the same price.

Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?

Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?

Answers

Step-by-step explanation:

If Aleah buys 2 DVDs for $6 and 2 CDs for $8 we can well assume that the DVDs are $3 dollars each and the CDs are 4 Dollars Each. If ling wants to buy 4 DVDs You would multiply how many DVDs she's buying with the price of the DVDs so (4x3=12) so Ling would have to pay $12 for the DVDs and $8 on the CDs

Pierre wants to spend $20 so with the previous information we can come to the solution that Pierre can buy 4 DVDs and 2 CDs for $20.

Answers

Answer:

If you multiply or divide both the top of a fraction and the bottom of a fraction by the same number, so for example:

[tex]\frac{2}{4}[/tex]÷[tex]\frac{2}{2} = \frac{1}{2}[/tex]

1/4 = 2/8

4/2 = 2/1 or 2

2/3 = 4/6

6/8 = 3/4

1/3 = 2/6

1/4 = 2/8

1/2 = 2/4

4/6 = 2/3

3/6 = 1/2

Answerk:

The answer is

[tex] \frac{1}{2} = \frac{2}{4} = \frac{3}{6} \\ \frac{2}{3} = \frac{4}{6} [/tex]

PART A

A= 51 (vertically opposite)
B= 129 (angles on a straight line and supplementary angles)
D= 129 (vertically opposite)
W= 129 (corresponding angles)
X = 51 (co-interior angles, angles on a straight line, supplementary angles and corresponding angles)
Y = 129 (vertically opposite)
Z = 51 (supplementary angles, angles on a straight line)

PART B
Z and y are supplementary angles because they are on a straight line meaning they add up to 180 degrees.

Every New Year's Day, Cody brings 15 candies for each of his grandchildren and
12 more candies for the adults to share.
Let g represent the number of Cody's grandchildren and c represent the total
number of candies he brings.
Find the value of c when g = 7.
C= ?

Answers

Answer:

c = 117

Step-by-step explanation:

g=7

c = 15g + 12

c = 15x7 + 12

c = 105 + 12

c = 117

C=117 is the correct answer

The Scenario: Your cousin Caleb has a dog-walking business, and you'd like to start one in your own neighborhood. Caleb has had his business for more than a year and has experimented with different prices for his services. He is willing to share what he has learned with you as you begin to plan your business. The Project: Use the information provided in the Performance Task to learn more about your competition and the costs of your business. See what you can discover by looking at Caleb's sales records to help you decide how to set up and price your own dog-walking services. Use the questions below to help you gather information and get your new business off to a profitable start. Understanding the Competition 1.

What are the break-even points of the profit function (the values of x where profit equals 0)? Use the quadratic formula. (4 points: 2 points for each x-value) 11. According to your model, between what two prices should you price your service? Why would you want to keep your price between those limits?
