Cheryl is planning to go to a four-year college in two years. She develops a monthly savings plan using the estimates shown. Wha
Alik [6]

Answer:

$541.67 per month

Step-by-step explanation:

Tuition and other expenses = $8,250 per semester.

There are two semesters in a year

She has 4 years to spend

Total semester=4years*2semesters

=8 semesters

4 years in college which is a total of 8 semesters.

Total Tuition and other expenses = $8,250 * 8

= $66,000

She needs a total of $66,00 to complete her college

Assistance from parents=$15,000

Financial aid(per semester)=$4750

Total financial aid=$38,000

Total assistance=

Assistance from parents+ financial aid

=$15000+$38,000

=$53,000

Total savings=Total amount needed - Total assistance

=$66,000 - $53,000

=$13,000

She needs to save $13,000 in two years

There are 12 months in one year

2 years=2*12=24 months

Monthly savings=Total savings/24 months

=$13,000/24

=$541.666666

To the nearest cent

=$541.67

The length of a swimming pool is 4 feet longer than 2 times its width. If the perimeter of the pool is 128 feet, what is the wid
alexandr1967 [171]
P = 2(L + W)
P = 128
L = 2W + 4

128 = 2(2W + 4 + W)
128 = 2(3W + 4)
128 = 6W + 8
128 - 8 = 6W
120 = 6W
120/6 = W
20 = W <=== width is 20 ft

L = 2W + 4
L = 2(20) + 4
L = 40 + 4
L = 44 <=== length is 44 ft

At an important​ meet, Allyson won the​ women's 100 meters in 12.24 seconds. Find her average rate.
otez555 [7]

The rate is 8.17 meters per second

Further explanation:

In order to find the rate we have to divide the distance covered by the woman by the time she covered it in.

Given

Distance=d=100\ meters\\Time=t=12.24\ sec\\So,\\Rate=\frac{d}{t}\\=\frac{100}{12.24}\\=8.17\ ms^{-1}

The rate is 8.17 meters per second

Reduce to simplest form. -\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=− 8 7 ​ −(− 6 5 ​ )=minus, start fraction, 7, divided by, 8, e
slavikrds [6]

Answer:

-\dfrac{1}{24}

Step-by-step explanation:

We are required to reduce the expression below to its simplest form

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)

<u>STEP 1: </u>Remove the brackets

Take note that the product of same sign(- and -) will give you the addition sign.

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{7}{8}+\dfrac{5}{6}

<u>STEP 2:</u> Find the Lowest Common Multiple of 8 and 6

Lowest Common Multiple of 8 and 6 is 24

<u>STEP 3:</u> Use the LCM to Simplify

-\dfrac{7}{8}+\dfrac{5}{6}=\dfrac{(-3X7)+(5X4)}{24}\\=\dfrac{-21+20}{24}\\=\dfrac{-1}{24}\\=-\dfrac{1}{24}

Therefore:

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{1}{24}
