How many 2-digit numbers are multiples of either 5 or 7?

Answers

Answer 1

Answer:

46

Step-by-step explanation:

he count of numbers from 1 to n that are divisible by k is integer part of (n/k).

So the numbers from 1 to 99 divisible by 3 is int(99/3) = 33

Those divisible by 5: int(99/5) = 19

From the sum of those two, subtract those divisible by 15 = int(99/15) = 6

That gives you 33+19-6 = 46.

Now subtract the 1 digit numbers: 3, 5, 6, 9, or four of them

46 - 4 = 42 is the answer.

The volume of a figure is 3250 cm^3. If the dimensions are multiplied by 1/5, what will be the volume of the new figure? Numerical answers only

Answers

Answer:Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Step-by-step explanation:

The solution is: 216.6 cm^3 will be the volume of the new figure.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

we know that,

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

here, we have,

The volume of a figure is 3250 cm^3.

now, we have,

If the dimensions are multiplied by 1/5,

then, we have,

Volume = length/5 x width/5 x height/5.

or, Volume = length x width x height / 15

or, Volume = 3250/ 15 cm^3

or, V = 216.6 cm^3

Hence, 216.6 cm^3 will be the volume of the new figure.

Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)

y=

Answers

Answer:

y = -2x - 8

Step-by-step explanation:

We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.

We already know that the slope is -2, so that means m = -2.

We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.

Thus, our equation is: y = -2x - 8.

Please help FAST

Answers

Answer:

$3.75/lb

Step-by-step explanation:

First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.

[tex]\frac{13.5}{3.6} =\frac{x}{1}[/tex]

Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.

[tex]13.5 * 1 =13.5\\3.6*x=3.6x[/tex]

Set these two equal to each other.

[tex]13.5=3.6x[/tex]

Divide both sides by 3.6 to get x.

[tex]\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75[/tex]

For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.
