The dimensions of a rectangular prism are shown below:

Length: 1 1/2 feet
Width: 1 foot
Height: 2 1/2 feet
The lengths of the sides of a small cube are 1/2 foot each.

Part A: How many small cubes can be packed in the rectangular prism? Show your work.

Part B: Use the answer obtained in part A to find the volume of the rectangular prism in terms of the small cube and a unit cube.


Correct answers: Brainliest and a Thanks!
Incorrect answers: 1-2 star (Make sure you know the answers please!)
Improper answers: Reported and 1 star (No links!!)

Answers

Answer: 30 cubes can be packed.

Step-by-step explanation: The cubes are 1/2 foot each, so 5 can fit in 2 1/2 feet, 3 can fit in 1 1/2 feet, so if you multiply these together, you will get 15, and then when you multiply that by 2 (1 foot) you get 30.

Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.

Answers

It would be A and C.

ANSWER : A AND D.

Step-by-step explanation:

the water current would be 2 mph and the canoe is 4 mph

See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.

The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.

The answers should be A and D.

the temperature at 2 pm is 27° at 2 am the temperature has fallen to -4° what is the total difference in temperature from 2:00 pm to 2:00 am???

Answers

Answer:

The temperature difference is equal to 27-(-4)=31.

Step-by-step explanation:

Answer:

31° .

Step-by-step explanation:

we need to calculate the temperature difference between 2 pm and 2 am we can get the difference by subtracting the temperature at 2 am from the temperature at 2 pm

the temperature at 2 pm is 27°  

the temperature at 2 am is -4°

the temperature difference between 2 pm and 2 am is:

27° - (-4)°  = 31°

The elevation of Location 1 is 20 feet above sea level and the elevation of Location 2 is 50 feet below sea level.
Which comparison of these locations is both true and correctly justified?
A. Because 20 < 50, Location 1 is higher.
B. Because 20 < 50, Location 2 is higher.
C. Because –50 < 20, Location 1 is higher.
D. Because –50 < 20, Location 2 is higher.

Answers

Answer:

C.

Step-by-step explanation:

Location 1 is 20 feet ABOVE the sea level while Location 2 is 50 feet BELOW the sea level.

Location 1 would be 20

Location 2 would be -50

And think of the greater than and lesser than symbol as a alligators mouth it would go towards the bigger number so, -50 < 20, Location 1 is higher, is the answer.

your answer is C i think!

First one: 3×4÷2

Since multiplication and division have the same power, you do the equation in order.

3×4=12

12÷2=6

Second one: 4+16-10

Since addition and subtraction have the same power, you do the equation in order.

4+16=20

20-10=10

Third one: (1+2)+3×4

You have to do the parentheses first...

1+2=3

Now you have to do multiplication since multiplication goes first (according to PEMDAS)

3×4=12

Now you have to add (3) and (12)

3+12=15
