Answer:

A approximation of 34 minutes and 30 seconds each day .

Step-by-step explanation:

First you would need to convert 4 hours to minutes , so 1 hour equals 60 minutes - 60 min = 1 hour, 60 min times 4 = 240 minutes in total. There are 7 days in total of the week, 240 minutes - 7 days of the week : 240 divided by 7 , equals a approaximation of 34 minutes and 30 seconds each day.

Answer: 45

100% of 18 = 18

50% of 18 = 9

18 + 18 = 36 = 200%

36 + 9 = 45 = 250%

:)

Answer: 45

Step-by-step explanation:

To find a percentage of a number, like what we're being asked to do, you multiply the number ( 18 in this case ) with the decimal form of the percentage. So, since we know 100% is equal to 1, 150% is equal to 1.5 and so on, 250% must be equal to 2.5. Since we know this, we now do:

2.5 x 18 = 45.

Answer:

Step-by-step explanation:

Central tendency means “the statistical measure that identifies a single value as representative of an entire distribution." These measures include mean, median, and mode.

Andrew scores 79, 86, 63, and 82 on his tests.

63, 79, 82, 86

Mean: 79 + 86 + 63 + 82 = 77.5 or

Median: 79 + 82 = 80.5

(you have to add these numbers bc there is no exact median as none are repeating)

Mode: There is no exact mode since there is no repeating numbers.

He should use the mean bc the mean is a pretty good number.

I'm not sure if you would want to tell your mother that you're barely getting an average. or higher than failing.

either way, hope this helps :)

Answer: The solution for the system is (2, -7)

Step-by-step explanation:

Ok, here we have linear relationships.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case, we have two lines:

ya, that passes through:

(-8, -5) and (-3, -6)

Then the slope is:

a = (-6 - (-5))/(-3 - (-8)) = (-6 + 5)/(-3 + 8) = -1/5

now, knowing one of the points like (-3, - 6) we can find the value of b.

y(x) = (-1/5)*x + b

y(-3) = -6 = (-1/5)*-3 + b

-6 = 3/5 + b

b = -6 - 3/5 = -33/5

then the first line is:

ya =  (-1/5)*x  -33/5

For the second line, we know that it passes through the points:

(-8, -15) and (-3, -11)

Then the slope is:

a = (-11 - (-15))/(-3 -(-8)) = (-11 + 15)/(-3 + 8) = 4/5

The our line is:

y(x) = (4/5)*x + b

and for b, we do the same as above, using one of the points, for example (-3, -11)

y(-3) = -11 = (4/5)*-3 + b

b = -11 + 12/5 = -(55 + 12)/5 = -43/5

then:

yb = (4/5)*x - 43/5.

Ok, our system of equations is:

ya = (-1/5)*x  -33/5

yb = (4/5)*x - 43/5.

To solve this, we suppose ya = yb

then:

(-1/5)*x + -33/5 = (4/5)*x - 43/5.

-33/5 + 43/5 = (4/5)*x + (1/5)*x

10/5 = 2 = (4/5 + 1/5)*x = x

2 = x

now we evaluate x = 2 in one of the lines:

ya = (-1/5)*2 -33/5 = -2/5 - 33/5 = -35/5 = -7

Then the lines intersect at the point (2, - 7), which is the solution for the system.

Answer:

-7 (a + 2b + 4)

Step-by-step explanation: hope this helps!

Answer: the answers  is -7 ( a + 2b + 4 )

Step-by-step explanation:

-7a - 14b - 28

you rewrite -28 as 4 * 7

you rewrite -14 as 2 * 7

-7a + 2 * 7b + 4 * 7

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

Volume equals 1632

Step-by-step explanation:

V=Bh

B=base area, to get B use the equation πr².

H= height  

Side A= 12

Side B= 10

Side C= 10

For the height we will use 34, or the height of the prism.

48*34 equals 1632, And your volume is 1632.

There is no multiplication here, and there are also no like terms, so terms with different variables cannot be combined due to the lack of multiplication. This expression cannot be simplified, only rearranged. Therefore, expressions that appear to simplify it:

13abc
7ab + 6c
5a + 8bc

Are not equivalent. Therefore:

2b + 5a + 6c, which only rearranges the expression, is equivalent.

Answer: 2b + 5a + 6c

Step-by-step explanation: The Equivalent expressions of the given expression is a 2b + 5a + 6c. Thus, option D is a correct.

According to the statement

We have to find that the equivalent expression.

So, For this purpose, we know that the

Equivalent expressions are expressions that work the same even though they look different.

From the given information:

The given expression is a 5a + 2b + 6c

Then

1) 13abc

It is completely different from the 5a + 2b + 6c

2) 7ab + 6c

It is also completely different from the 5a + 2b + 6c

3) 5a + 8bc

It is also completely different from the 5a + 2b + 6c

4) 2b + 5a + 6c

It is sams as the  5a + 2b + 6c because of the some same coefficients of the variables.

So, The Equivalent expressions of the given expression is a 2b + 5a + 6c. Thus, option D is a correct.

2x+12.8=117.6

We move all terms to the left:

2x+12.8-(117.6)=0

We add all the numbers together, and all the variables

2x-104.8=0

We move all terms containing x to the left, all other terms to the right

2x=104.8

x=104.8/2

x=52+0.8/2
