The store has 28 notebooks in packs of 4 three packs are sold how many packs of notebooks are left

Clayton says that 2 1/2 + 3 3/5 will be more than 5 but less than 6 since 2 + 3 is 5. Is Clayton’s reasoning correct? Prove him

He is wrong...

2 1/2 + 3 3/5 = 97/20

Simplified, I believe the answer is 4 17/20

Jake has finished pouring 4,865 cubic feet out of a total of 27,000 cubic feet of concrete. What percent of the job has he compl

anzhelika [568]

The total is the 100% and that is 27000, the question is what percentage is 4865
We can use a simple rule of three, direct proportion to solve:
27000 ft^3 --------> 100%
4865 ft^3 ---------> x
x =(4865)(100)/27000
x = 18.02
therefore 4865 ft^3 is 18.02% of 27000 <span>ft^3</span>

1/2x-7=1/3(x-12) pls find the value of x

KIM [24]

Answer:

x=18

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(1 /2 )x−7 = (1 /3 )x−4 (Distribute)

Step 2: Subtract 1/3x from both sides.

(1 /6) x−7=−4

Step 3: Add 7 to both sides.

(1 /6 )x=3

Step 4: Multiply both sides by 6.

x=18

Norm must pay to have trash collected he can put out 1 barrel of trash per week a rectangler container measure 32 inches by 18 i

Ainat [17]

Answer:

The Cycling Rick container can hold more trash.

Step-by-step explanation:

The rectangular container is basically a rectangular prism, so to find its volume, we are using the formula for the volume of a rectangular prism:

$V=whl$

where

$V$ is the volume

$w$ is the width

$h$ is the height

$l$ is the length

We know that the rectangular container is 32 inches by 18 inches by 10 inches, so $l=32in$ , $w=18in$ , and $h=10in$ . Let's replace the values in our formula:

$V=whl$

$V=(18in)(10in)(32in)$

$V=5760in^3$

The rectangular container can hold 5760 cubic inches of trash.

Now, the Cycling Rick container is basically a cylinder, so to find its volume, we are suing the formula for the volume of a cylinder:

$V=\pi r^2h$

where

$V$ is the volume

$r$ is the radius

$h$ is the height

We know that the its height is 30 inches, so $h=30in$ . Since the container is 20 inches wide, its diameter is 20 inches, and since the radius is half the diameter, $r=\frac{20in}{2} =10in$ . Let's replace the values:

$V=\pi r^2h$

$V=\pi (10in)^2(30in)$

$V=9424.78in^3$

The Cycling Rick container can hold 9424.78 cubic inches of trash.

Since 9424.78 cubic inches is bigger than 5760 cubic inches, we can conclude that the Cycling Rick container can hold more trash.
