Mary's 3 hamsters each eat three-eighths of cup of grain a day, if she has 6 and 3/4 cups of grain, how many days will the grain
muminat
Hello!

3/8 times 3 equals 9/8 which is also 1 1/8. If you multiply 3/4 by two (numerator and denominator) then you will get 6/8. And if you multiply 9/8( I just find it easier with 9/8) by 6 you will get 54/8. And the grain will last for 6.75 days.

I may be wrong let me know.
Hope this helps!

The temperature falls from 0 degrees to – 12.3 degrees in 3.5 hours. Which expression finds the change in temperature
MatroZZZ [7]

Answer:

3.514 degrees per hour

Step-by-step explanation:

To find change per hour, you find the slope, which is change in output (temperature) over change in input (hours)

y2-y1 / x2-x1

-12.3 - 0 / 3.5

3.514 degrees per hour

A large cube has a volume of 1 cubic unit. A small cube has a volume of 1 27 of a cubic unit. What is the difference between the
ExtremeBDS [4]

Given:

Volume of Large cube = 1 cubic unit

Volume of small cube = \dfrac{1}{27} cubic unit

To find:

The difference between the edge length of the large cube and the edge length of the small cube.

Solution:

Let the edges of large and small cubes are a_1 and a_2 respectively.

We know that, volume of a cube is

V=(edge)^3

Volume of Large cube = 1 cubic unit

(a_1)^3=1

Taking cube root on both sides, we get

a_1=1

So, edge of large cube is 1 unit.

Volume of small cube = \dfrac{1}{27} cubic unit

(a_2)^3=\dfrac{1}{27}

Taking cube root on both sides, we get

a_2=\dfrac{1}{3}

So, edge of large cube is \dfrac{1}{3} unit.

Now, difference between them is

d=a_1-a-2

d=1-\dfrac{1}{3}

d=\dfrac{3-1}{3}

d=\dfrac{2}{3}

Therefore, the difference between the edge length of the large cube and the edge length of the small cube is \dfrac{2}{3} unit.
