On Monday, 344 students went on a trip to the zoo. All 6
buses were filled and 8 students had to travel in cars. How many students were
in each bus ?

Answers

Answer:

56 students were in each bus is our answer

Step-by-step explanation:

This is true because if 8 students went in cars then we have to subtract 8 from 344, so we get 336 then from there we divide 6 from 336 giving us 56, thus 56 is our answer.

Your Welcome, Have A Splendid Day, And Hope This Helps!!!

the answer is 56

if you subtract the 8 students from the total number you get 336

336 students divided by 6 busses equals 56 students in each bus

1. Find the perimeter of the base of the treasure chest in feet

2. Find the area of the base of the treasure chest in square feet.

3. Can you use the expression from part c in exercise (#3) to find the surface area of the treasure chest in exercise 2? Explain

4. One cubic inch of sand weighs about 1 ounce. Find the weight of the treasure chest (in pounds) after it is filled with sand. Assume that the chest weighs 20 pounds when empty.
*There are 16 ounces in a pound

Answers

Answer:

2.  7

4. 60

Step-by-step explanation:

1. The base of the treasure chest is the bottom edge
Because most chests are rectangles, we can assume that the base is also a rectangle
This means that the perimeter would be 3+3+2+2, which is 10 ft


2.
To find the area of the chest’s base, you must multiply 3 by 2

3*2 is 6, so the answer is 6 feet squared

3.
I’m not completely sure what this question is asking, but I’ll do my best

It looks like it is asking if you can find the surface area by multiplying the base by one of the side lengths (again, not sure which one because it’s not labeled)

This wouldn’t work regardless of the side length, however, because base times height is equal to the volume of the chest and not the surface area


4. To do this, it would be easier to find how much sand can fit in the chest, and then do weight after you have that figure

There are 12 inches in a foot, so the measurements of how much sand can fit in the chest could be found by multiplying 12 by the side length
This would leave you with measurements of 36, 24 and 24
Volume is base * height, so first multiply the two base measurements (36 and 24)
This leaves you with 624
Multiply that by height (24) and you get 14,976 cubic inches of sand

Because each cubic inch of sand weighs about 1 ounce, we know that the weight of the sand is 14,976 ounces

To find out how much that is in pounds, divide 14,976 by 16

This leaves you with 936 lbs
Add the additional 20 that comes from the chest and you get 956 lbs total
The chest weighs 956 pounds when filled with sand

Hope that helped!

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth

Answers

Answer:

V = Π (4)2*12

V = 603.19 cm3

Step-by-step explanation:

A soup can is a cylinder.

The formula for volume of a cylinder is the following: V= Πr2h.

 

We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).  

The formula asks for radius so we divide the diameter by 2.  

r =8/2 = 4.

Now we can just plug the numbers into the formula

 

V = Π (4)2*12

V = 603.19 cm3

 

Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

V = Π (4)2*12
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.

We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula

V = Π (4)2*12
V = 603.19 cm3

Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

Find the value for q for the following equation: 15q – 16 = 4(2q + 3)

Answers

Answer:
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4
Step 1: Multiply 4 by 2q and 3

Now your equation is 15q - 16 = 8q + 12

Step 2: Subtract 8q from both sides

Now your equation is 7q - 16 = 12

Step 3: Add 16 to both sides

Now the equation is 7q = 28

Step 4: Divid each side by 7

Q= 4

Using Cartesian coordinates, a scatter plot (also known as a scatterplot, scattergraph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that shows the values of typically two variables for a set of data. One more variable can be shown if the points are coded (by color, shape, or size).

Answer:

A.

Step-by-step explanation:

The volume of rectangular prism is l x w x h

So, 12 x 6 x 8 =576

Volume of triangular prism is l x w /2 x h

So, 6x8=48/2= 24

24x12=288

576/288=2

This shows that the rectangular prism is 2 times larger than the triangular prism.

Therefore, the answer is A.

How many cubes that measure 2 inches by 2 inches by 2 inches would fit inside a cube that measures 10 inches by 10 inches by 10 inches? Justify.

Answers

25, because a cube that is 10x10 would have an area of 100. and the cubes that are 2x2 would have an area of 4. so you take 100 and divide it by 4. answer is 25.

The number of the small cube that fits inside the larger cube is 125.

Given to us,

Side of small cube, s = 2 inches,

Side of larger Cube. S = 10 inches,

We know that volume of a cube is given by , where "a" is the side of the cube.

Volume of the small cube = s³ = 2³ = 8 in.³

Volume of the Larger cube = S³ = 10³ = 1000 in.³

The number of the small cube that fits inside the larger cube

                                           [tex]\bold{=\dfrac{Volume\ of\ the\ Larger\ cube}{Volume\ of\ the\ small\ cube} }[/tex]

                                           [tex]\bold{=\dfrac{1000}{8} = 125 }[/tex]

Hence, the number of the small cube that fits inside the larger cube is 125.
