Answer:

2250 hours of 300 computers used in average(mean) in a week

Step-by-step explanation:

300 * 7.5 hours(average hours) = 2250 hours

how to find mean or average of any amount of numbers ?

Basiccaly just add all numbers and then divide it by the numbers you added

example: The mean of 5-10 hours would be

                5 + 10 = 15

                15/2 = 7.5

Answer:

18.75

Step-by-step explanation:

got this from calculator so might be wrong

u add 25 percent to 15

Answer:

B. 7√2

Step-by-step explanation:

One of the trigonometry formulas to find a missing side is:

sin θ = opp/hyp

Substituting those values in with the ones we have, we will get:

sin (45deg) = x/14

√2/2 = x/14

14(√2/2) = x

x = 7√2

Answer: 144

Step-by-step explanation:

so you find 20% of 150 which is 30 and because it is a decrease then you would do 150 minus 30 and that is 120. you would  now find 20% of 120 and that is 24 so you do 120 plus 24 and that is 144.

Answer:

i would go with D to

Step-by-step explanation:

[C] [tex]2^4[/tex]

Step-by-step explanation:

I think each answer choice are;

[A] [tex]2^2[/tex]  

[B] [tex]4^4[/tex]

[C] [tex]2^4[/tex]

[D] [tex]8^2[/tex]

[E] [tex]2^8[/tex]

Now we have to solve each by multiply:

[A] [tex]2^2[/tex]              {2*2 = 4}

[B] [tex]4^4[/tex]             {4*4*4*4=256}

[C] [tex]2^4[/tex]            {2*2*2*2=16}

[D] [tex]8^2[/tex]            {8*8=64}

[E] [tex]2^8[/tex]           {2*2*2*2*2*2*2*2=256}

Hence, the correct answer is [C] [tex]2^4[/tex]

Answer:

student's age = x years.

Teacher's age = 2x + 6

Principal's age = 3x + 10

------------------------------------------

Difference between ages ,

[tex]\bold{(3x + 10) - (2x + 6)} \\\bold{ = > 3x + 10 - 2x - 6} \\ \bold{= > x + 4}[/tex]

Answer:

Step-by-step explanation:

10 hours - 2 hours 25 minutes - 3 hours 35 minutes

Lets just do this

2 hours 25 minutes + 3 hours 35 minutes

25 minutes + 35 minutes = 60 minutes

60 minutes = 1 hour

now we have 2 hours + 3 hours + 1 hour

2 + 3 +1  = 6

now we have 10 hours - 6 hours

10 - 6 is 4

4 hours.

Answer: 1001

Step-by-step explanation:

1) you would do 700x43% and that would = 301

2) then you add 301 to 700, 301+700=1001 cars

Solution:

We know that:

Substitute the length, breadth, and height to find the volume of the rectangular prism.

Now, let's simplify the LHS.

Further simplify the equation by dividing 9 both sides.

Thus, the height of the rectangular prism is 10 feet.

Answer:

$2,675

Step-by-step explanation:

7% of $2,500 is $175. Adding $2,500 and $175 gets you $2,675

Hope this helps, and I’d appreciate brainliest but if not it’s okay!

Answer:

If the sales tax rate was 7%, Mr. Osmond would have bought the $2,500 computer for a total of $2,675.

Step-by-step explanation:

To calculate the total Mr. Osmond paid for his computer, we must find 7% of the computer's cost, $2,500, and then add that figure to $2,500.

To find 7% of $2,500, multiply 2,500 by the decimal form of 7%, .07:

Since we know that 7% of $2,500 is $175, we can now add that figure to $2,500:

[tex]2500+175=2675[/tex]

Therefore, we can conclude Mr. Osmond paid a total of $2,675 for the computer.

Answer:

the domain of y=4x is all real numbers.

Any number you can think that is not imaginary and certain transcendental numbers fall into the domain of y=4x

Answer:

True

…………………………………………

Answer:

Step-by-step explanation:

true

Step-by-step explanation:

the easiest approach for a given point and slope of the line is the point-slope form

y - y1 = a(x - x1)

with "a" being the slope, and (x1, y1) being a point on the line.

so, we get

y - 8 = 11(x - 1)

if we need the slope-intercept form

y = ax + b

we simplify the point-slope form

y - 8 = 11x - 11

y = 11x - 3

Answer:

87

Step-by-step explanation:

9 2/3 = 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 6/9 = 87/9

Answer: 87 ninths

Step-by-step explanation:

See how many 1/9ths fit inside 9 2/3 using division

[tex]9\:\frac{2}{3}\div \frac{1}{9}[/tex] or

[tex]\frac{29}{3}\div \frac{1}{9}[/tex]

[tex]=\frac{29}{3}\times \frac{9}{1}[/tex]

[tex]= \frac{87}{1}[/tex]

[tex]=87[/tex]

Test to see if 1/9 goes into 9 2/3 87 times

87 * 1/9

[tex]= \frac{87}{9}[/tex]

[tex]=\frac{29}{3}[/tex]

29/3 as a mixed fraction is 9 2/3. So therefore, there are 87 ninths in 9 2/3

Answer:  49583.54 dollars

==============================================================

Work Shown:

P = 37000 is the principal (aka amount loaned out)

r = 0.05 is the interest rate in decimal form

t = 6 is the number of years

n = 1 tells us we are compounding 1 time per year (aka annual compounding)

Those four values are plugged into the formula below and you use a calculator to simplify

A = P*(1+r/n)^(n*t)

A = 37000*(1+0.05/1)^(1*6)

A = 49583.538703125

A = 49583.54 is the full amount to pay back

Side note:

The amount of interest paid is A - P = 49583.54 - 37000 = 12583.54

Answer:

113.4 points.

Explanation:

Use the Percent Equation to solve this answer.

378(30%) = ?

113.4

Answer:

( 7 , 7 )

Step-by-step explanation:

Translation:

( 2 , - 3 ) ------> ( 2 + 5 , - 3 - 4 ) = ( 7 , - 7 )

Reflection:

( 7 , - 7 ) ------> ( 7 , - ( - 7 ) ) = ( 7 , 7 )

so we take 58 and -3 and the equation to find differences

is x - y

so x=58

and y=-3

so then we do this

58 - (-3)

so 61  is correct  

hope this helps
