Answers

Answer:

The number he thought of was 13

Step-by-step explanation:

Revers the problem

3.5 * 3 = 10.5

10.5 - 4 = 6.5

6.5 * 2 = 13

The number was 13 if Toby thinks of a number less than 15. He divides it by 2 and then he adds 4.

C = 100.48 mm

Perimeter of the figure = 20 + 20 + 1/2 (circumference)

P = 40 + 1/2 (100.48)

You notice these two old suitcases stacked in the closet. The smaller suitcase is 25 inches x 8 inches x 9 inches and the larger suitcase is 75 inches x 20 inches x 18 inches.



The bigger suitcase is how many times larger than the smaller suitcase? HINT: You will need to divide on this one.





You decide to use the larger suitcase to transport rectangular prism watermelons back home. The watermelons are about 720 cubic inches. If one of the watermelons is about 10 inches long and 9 inches wide, about how tall would it be? (Hint: V=LxWxH, so plug h in 720=10x9xH and solve for H).







If the watermelons are about 720 cubic inches, what is the MAXIMUM amount of watermelons you’ll be able to bring home in your larger suitcase, assuming all you have in the suitcase is the watermelons. (Hint: Divide the larger suitcase volume and the volume of the watermelon).

Answers

The given dimensions of the, Check Box, bag, suitcase, and watermelons, we have;

First part;

Volume of the Check box is 2,772 in.³

Volume of the black bag is 1728 in.³

Volume of the blue bag is 2700 in.³

The bag that will definitely fit in the Check Box is; The black bag

Second part;

The number of times, the bigger suit case is larger than the smaller suit case is 15 times

Third part;

The height of the watermelon = 8 inches

The maximum number of watermelon the larger suitcase can carry is 36 watermelon

How can the volume of the suitcases be found?

Volume of the Carry-on baggage Check box, V_c can be found as follows;

V_c = 22 × 14 × 9 = 2772

Volume of the Check box, V_c = 2,772 in.³

Volume of the black bag, V_b, can be found as follows;

V_b = 18 × 12 × 8 = 1728

Volume of the black bag, V_b = 1728 in.³

Volume of the blue bag, V_bl, can be found as follows;

V_bl = 18 × 15 × 10 = 2700

Volume of the blue bag, V_bl = 2700 in.³

Given that the height, depth and width of the black bag are smaller than the height, depth and width of the check box

The bag that will definitely fit in the Check Box is; The black bag

Second part;

Volume of the smaller suitcase is found as follows;

V_s = 25×8×9 = 1800

Volume of the bigger suitcase is found as follows;

V_b = 75 × 20 × 18 = 27,000

The number of times, the bigger suitcase is larger than the smaller suitcase is therefore;

n = 27,000 ÷ 1809 = 15

The number of times, the bigger suit case is larger than the smaller suit case is 15 times

Third part

The volume of the watermelon = 720 in.³

Which gives;

10 × 9 × H = 720

H = 720 ÷ (10 × 9) = 8

The height of the watermelon = 8 inches

To maximize the number of watermelons, we have;

The length, 10, is a factor of 20

The width, 9, is a factor of 18

Therefore, we have;

Two rows of watermelon, and two layers of watermelon

Number of watermelon in a row is therefore;

R = 75 ÷ 8 ≈ 9

Maximum number of watermelon is therefore;

Max_n = 9 × 2 × 2 = 36

The maximum number of watermelon the larger suitcase can carry is 36 watermelon

Now solve for y

Answers

Answer:

y - 2 = 6 (x - 1)

Step-by-step explanation:

Slope intercept form equations look like this:

y - y1 = m (x - x1)

***m = [tex]\frac{y2-y1}{x2-x1}[/tex]

Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:

y - 2 = m (x - 1)

To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

[tex]\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6[/tex]

Now that we know m = 6, let's plug that back into the original equation to get our final answer:

y - 2 = 6 (x - 1)

A recycling bin is in the shape of a right rectangular prism. The bin is 9 meters long, 5 meters wide, and 313 meters tall.

What is the volume of the recycling bin?

Answers

Answer: 14085 m^3.

Step-by-step explanation: To find the volume of a right rectangular prism, you need to multiply the length, width, and height.  The equation is below:

l x w x h = V where l is the length, w is the width, h is the height, and V is the volume of the right rectangular prism.

The length of this recycling bin is 9 meters, the width is 5 meters, and the height is 313 meters.  Now that we know the length, width, and height, we can substitute the variables with the information we've gathered.

9 x 5 x 313 = 14085.

Therefore, 14085 m^3 is your answer.

The original price was $129.78.

Answer:

C. 3/4 (third option).

Step-by-step explanation:

Use the slope-intercept formula.

Slope-intercept formula:

The m represents the slope.The b represents the y-intercept.

So, the slope is 3/4 and y-intercept is -1.

10 m

Answers

Answer:

I believe it is 106 Square meters

Step-by-step explanation:

Easiest way to find area for these kind of shapes is to break them into smaller rectangles, this specific one can be broken 3 ways...

Right: 4m long, 7m tall

Top: 10 long, 5 tall *(12-7)*

Left: 4m long, 7m tall

*To find incomplete ones, you find clues in other sides, for instance the whole side was 12, the broken part was 7, therefor you just subtract 7 from 12, giving you 5 for the top.*

Then you just multiply...

4x7=28
4x7=28
10x5= 50

Now, you have the area for three individual smaller rectangles. So you simply add them together to get the whole shapes area...

28+28+50=106

Therefor, your answer should be 106 square meters- if I'm not mistaken.
