Answer:

17.5 is the correct answer

Answer:

12.5 ft

Step-by-step explanation:

7.5 squared and 10 squared

you add both of the squared numbers and then do the sqaure root of that number

Answer:

f(g(x)) = (5x)^2 = 25x^2

Step-by-step explanation:

If f(x) = x^2 and g(x) = 5x, then

f(g(x)) = (5x)^2 = 25x^2

Answer:

3 down, 4 up

Step-by-step explanation:

-3 is the X line, which starts on 0, if you subtract 3, or add -3, you would have to go down, 3 down. 4 is on the Y line, so you add, go left to add on the Y line, 4 up.

Always start with you X coordinate. Here is a tip to help you (X, Y)

Step-by-step explanation:

Answer:

22.5 mins

Step-by-step explanation:

To find what that video's length must be, subtract the previous videos' lengths from the requirement, 5 hours. (x is the video length of her fourth video)

7/8 + 1 1/4 + 2 1/2 + x = 5

To make adding these fractions easier, find a common denominator.

7/8 + 1 2/8 + 2 4/8 + x = 5

4 5/8 + x = 5

x = 3/8, or 22.5 minutes.

Answer:

[tex]\frac{3}{8} \text{ hours.}[/tex]

Step-by-step explanation:

Her first three videos totalled up to

[tex]\frac{7}{8} + 1\frac{1}{4} + 2\frac{1}{2}\\=\frac{7}{8} + \frac{5}{4} + \frac{5}{2}\\=\frac{7}{8} + \frac{5}{4} \cdot \frac{2}{2} + \frac{5}{2} \cdot \frac{4}{4}\\=\frac{7}{8} + \frac{10}{8} + \frac{20}{8}\\=\frac{7+10+20}{8}\\=\frac{37}{8}[/tex]hours. To meet the [tex]5 = \frac{40}{8}[/tex] hour goal the shortest fouth video she can make is [tex]\frac{40}{8} - \frac{37}{8} = \frac{3}{8}[/tex] hours, because if the fourth video was any shorter, she'd end up with less than [tex]\frac{37}{8} + \frac{3}{8} = \frac{40}{8} = 5[/tex] hours in total (this is called a proof by contradiction). We are now done.

-0.9, -4/5, -7/10, -1/2, -1/4

Answer:

The answer is -0.9, -4/5, -7/10, -1/2, -1/4.

Step-by-step explanation:

-4/5 = -0.80

-7/10 = -0.7

-1/2 = -0.5

-1/4 = -0.25

Answer:

The circumference is similar to the perimeter in that it is the total length needed to draw the circle.

We note the circumference as c.

c = 2πr

or

c = πd

This depends on whether or not you know the radius (r) or the diameter (d)

Let’s calculate one manually, for example.

If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.

Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.

Step-by-step explanation:

We have the equation [tex]5x-3y[/tex] and are given that [tex]x=-2, y=6[/tex].  To solve this equation, we simply replace the variables with their real value.  In action, this would be [tex]5(-2)-3(6)=-10-18=-28[/tex].

Answer:

2x

Step-by-step explanation:

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.

It is given that:

The GCF of 14x and 18xy​

As we know, GCF is the greatest common factor.

The greatest common factor of 14 and 18 or

GCF(14, 18) = 2

And the greatest common factor of GCF of x and xy

= x

the greatest common factor of 14x and 18xy is:

= 2x

Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

Answer:

  1.725×10²

Step-by-step explanation:

Your calculator or a spreadsheet can format the result of this division in scientific notation for you.

For the powers of 10, the applicable rule of exponents is ...

  (10^a)/(10^b) = 10^(a-b)

__

  [tex]6.900\times10^{10}\div4.000\times10^8=\dfrac{6.9}{4}\times10^{10-8}\\\\=\boxed{1.725\times10^2}[/tex]

Answer:

Yes.

Step-by-step explanation:

For a graph to be a function, it must have precisely one y-value for every x-value.

In this case, this graph is a function because it meets the requirements of having one y-value for every x-value.

A dotted line is not included in the solution so there is no equal sign.

The blue area is to the right of the dotted line so the solution is >

The line crosses the x axis at -2

The answer is : x-y > -2
