6.{6.G.A.4} Find the surface area. Answer without units. *
Agata [3.3K]

Answer:

392

Step-by-step explanation:

3 rectangular faces

7 x 16 = 112

7 x 16 = 112

7 x 16 = 112

2 triangular faces

1/2 x 7 x 8 = 28

1/2 x 7 x 8 = 28

Total surface area:

112 + 112 + 112 + 28 + 28 = 392

What is the slope of the line on the graph?
Bogdan [553]
Answer: 1/2

When looking at a graph, you need to follow the formula rise/run. This means that between two points, you need to find the distance up and down/left and right.

Looking at points (0,2) and (2,3), I see that the second point is 1 point higher. Let’s add that in for rise.

Rise/run

1/run

Now for run. The second point is 2 points to the right of the first one. Let’s add that in.

1/2

This is your answer! Hope this helps comment below for more questions :)

Hope made 3 different yo-yo's. She used 1 3/4 meters of string for the first yo-yo, 1 meter of string
Nat2105 [25]

Answer:

See explanation

Step-by-step explanation:

Your question is different from the attachment

Statement 1

1 adult + 5 Children

$4 for adult and total of $16 for both adult and children

Let

Cost of children skating = x

The equation is

4 + 5x = 16

Statement 2:

Cost of making a bike bag= $4

Selling price of the bike bag = $5

Profit = $16

Let x = number of bike bag

Profit = selling price - cost price

16 = 5x - 4x

16 = x(5 - 4)

Also written as

(5 - 4)x = 16

Statement 3:

Initial temperature = 16°C

Change in temperature per hour = 4°C

Final temperature = 5°C

Let

x = number of hours it changes

16 - 4x = 5

Hope made 3 different yo-yos. She used 1 3/4 meters of string for the first yo-yo, 1 meter of string for the second yo-yo, and a total of meters of string 4 1/3

length of first yo-yo = 1 3/4

length of second yo-yo = 1

Length of third yo-yo = x

Total = 4 1/3

Total length = length of first yo-yo + length of second yo-yo + length of third yo-yo

4 1/3 = 1 3/4 + 1 + x

4 1/3 = 2 3/4 + x

4 1/3 - 2 3/4 = x

13/3 - 11/4 = x

(52-33) / 12 = x

19/12 = x

x = 1 7/12
