How much more does the student need to save to buy the laptop

Mathematics
1 answer:
Harrizon [31]2 years ago
6 0

Answer:

A

Step-by-step explanation:

Starting amount =                             307.50

1 month saving = 100

5 month saving = 5*100                   <u> 500.00</u>

<u />

Total so far                                         807.50

Let the total amount be x

75% *x = 807.50

75/100 x = 807,59                              Multiply both sides by 100

75 x = 807.50 * 100                          

75 x = 80750                                      Divide by 75.

x = 80750 / 75

x = 1076.67

That is not the answer. That's the total cost of the laptop.

The amount needed is

Amount needed = Total Cost - what has been saved

Amount needed = ????

Total Cost = 1076.67

What has been saved = 807.50

Answer

Amount needed = 1076.67 - 807.50 = 269.17

You have a part time job. You work for 3 hours on Friday and 6 hours on Saturday. You also receive an allowance of $20 per week.
Svetradugi [14.3K]
$92 - $20 = $72, because we shouldn't take allowance into account
3 + 6 = 9, because that is the total number of hours this person works per week
We should just do this:
72 / 9 = 8
This means that this person earns $8 per hour at his part time job.

Solve the equation or formula for the indicated variable.
alex41 [277]
Subtract 3 both sides first. R-3=ts²

next, divide both sides by t, (R-3)/t=s²

finally, take the square root of both sides

√(R-3)/t = s. 2nd choice.

identify the amplitude and period of the function then graph the function and describe the graph of G as a transformation of the
mrs_skeptik [129]

Given the function:

g(x)=cos4x

Let's find the amplitude and period of the function.

Apply the general cosine function:

f(x)=Acos(bx+c)+d

Where A is the amplitude.

Comparing both functions, we have:

A = 1

b = 4

Hence, we have:

Amplitude, A = 1

To find the period, we have:

\frac{2\pi}{b}=\frac{2\pi}{4}=\frac{\pi}{2}

Therefore, the period is = π/2

The graph of the function is shown below:

The parent function of the given function is:

f(x)=cosx

Let's describe the transformation..

Apply the transformation rules for function.

We have:

The transformation that occured from f(x) = cosx to g(x) = cos4x using the rules of transformation can be said to be a horizontal compression.

ANSWER:

Amplitude = 1

Period = π/2

Transformation = horizontal compression.

It takes Emma 18 minutes to type and spell check 14 pages of a manuscript. Find how long it takes her to type and spell check 77
NNADVOKAT [17]

Answer:

99 minutes, or an hour and 39 minutes.

Step-by-step explanation:

It takes Emma 18 minutes to do 14 pages. That means that we can set up a proportion, where Emma uses 18 minutes to do 14 pages, which is equal to x minutes per page!

\frac{18}{14} =\frac{x}{1}

14x = 18

7x = 9

x = 9/7

So, each page takes 9/7 minutes for Emma to finish.

She will do 77 pages. 77 * (9/7) = 11 * 9 = 99.

So, it will take Emma 99 minutes, or an hour and 39 minutes, to type and spell check 77 pages.

Hope this helps!
