b. The area of another sheet of paper is 200 square inches. Write an equation that
gives the area, B, of this sheet of paper, in square inches, after being folded into
thirds n times.

Answer:

( 7 , 7 )

Step-by-step explanation:

Translation:

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

Reflection:

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

Answer:

45

Step-by-step explanation:

These work problems are always done in terms of fractions ie if both (Kevin & Eric) took 30mins to mow and Kevin took 1.5hrs (90mins) alone then we can make an equation like below

1/time took for both = 1/time took for Kevin + 1/time took for Eric

1/30 = 1/90+1/x    ==> calling time took for Kevin x

solving the above 1/x = 1/30-1/90

1/x=2/90

x=45

Given that Kevin takes 1.5 hours to mow the lawn alone and together

with Eric it takes 30 minutes The time it takes Eric alone is 45 minutes.

The time it takes Kevin to mow the lawn, K = 1.5 hours

The time it takes Kevin and Eric to mow the lawn, B = 30 minutes = 0.5 hours

Required:

The time it takes Eric to mow the lawn alone.

Solution:

Let K represent the time it takes Kevin to mow the lawn alone and let E

represent the time it takes Eric to mow the lawn alone, we have;

[tex]\mathbf{\dfrac{1}{K} + \dfrac{1}{E} }= \dfrac{1}{T}[/tex]

Which gives;

[tex]\dfrac{1}{1.5} + \dfrac{1}{E} = \dfrac{1}{0.5}[/tex]

Which gives;

[tex]\dfrac{1}{E} = \dfrac{1}{0.5} - \dfrac{1}{1.5} =\dfrac{4}{3}[/tex]

Therefore;

[tex]E = \dfrac{1}{\dfrac{4}{3} } = \dfrac{3}{4} = \mathbf{ 0.75}[/tex]

The time it takes Eric to mow the lawn alone, E = 0.75 hours

0.75 hours = 0.75 × 60 minutes = 45 minutes

The time it takes Eric to mow the lawn alone, E = 45 minutes

Answer:

He would pay less at the garden store.

Step-by-step explanation:

We have to find the unit prices of both shrubs.

The unit price is the cost per unit, and to find the unit price, divide the price by the number of units. 

72/6 = 12

77/7 = 11

He would pay less at the garden store because the unit price is lower than the nursery.

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.

is x - y

so x=58

and y=-3

so then we do this

58 - (-3)

so 61  is correct

Answer:

Square both sides.

When you do this the square root sign will be eliminated and u will be able to solve. So it will become just x2 + x - 2 and the left hand side you will need to do foil method and use distributive law

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:

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

Just add the hours together except the time he took for lunch. Then times that by how much money he makes per hour.

Answer:

Step-by-step explanation: Hi there.

First, add up the number of hours he worked (do not include lunch hours): 3.8+4.4=8.2

Then multiply those hours by how much he gets paid: 5.50*8.2=45.1

So the worker was paid $45.10.

Have a nice day! :)

Answer:

For this problem, we can assume that we deposits X money at 4.5% interest, than we can know that 2X were deposited at 5% interest, therefore we can get the equation of:  4.5%*X+5%*2X=2755, than we can get X=19000, so the 2X=38000, than we can concluded that: she deposited $19000 at 4.5% and $38000 at 5%.

19 inches is 48.26 and 39 hours is 2340 so 2340/48.26=48.427

Step-by-step explanation:

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.
