Step-by-step explanation:

5(6-3)=6+13 -simplify

30-15=6+13

Mary wants to fill in a cylinder vase. At the flower store they told her that the vase should be filled 3/4 for the flowers to

Alex Ar [27]

Answer:

About 376.99 cubic inches

Step-by-step explanation:

Cylinder has a volume of:

$V=\pi r^2h$

Where

V is the volume

r is the radius

h is the height

We need to find the volume of the cylinder, then multiply that answer by 3/4 to get the solution to this problem. First, the full volume of the cylinder.

Given

r = 4

h = 10

So,

$V=\pi r^2h\\V=\pi (4)^2 (10)\\V=502.65$

Now, we multiply by 3/4:

$502.65*\frac{3}{4}=376.99$

Mary should be vase to 376.99 cubic inches

The 2s in 6,228 name the value of the given digits in each number

Yuliya22 [10]

We have the digit 6,228.

We need to find the values of 2s in the digit 6228.

First of all we need to split the digits as per their place values.

6 is at thousands place in the digits 6228, so the place value of 6 is 6000 $(6 \times 1000)$ .

2 is at hundreds place in the digits 6228, so the place value of 2 is 200 $(2 \times 100)$ .

2 is also their at tens place in the digits 6228, so the place value of 2 is 20 $(2 \times 10)$ .

8 is at ones place in the digits 6228, so the place value of 8 is $(8 \times 1)$ .

So, first 2 in the digits 6,228 is at hundreds place and the second 2 is at tens place.
