Answer

Find out the  possible heights of her fourth plant.

To prove

Let us assume that the  possible heights of her fourth plant be x.

As given

Millie needs the average height of the plants she is buying to be atleast 73 inches.

She has selected three plants that are 70, 71, and 72 inches tall.

Average formula

Average formula = \frac{Total\ heights \ of\ plants}{Total\ number\ of\ plants}

Put the value

Here Total numbers of flowers = 4

Put in the formula

73\leq \frac{x + 70 + 71 +72}{4}

73\times 4 \leq (x + 70 + 71 +72)

292 \leq x + 213

292 - 213 \leq x

79 ≤ x

Therefore the possible height of the fourth plant be 79 .

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

aalyn [17]

Answer: The answer should be 38.

I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.

Step-by-step explanation:

2.3   (14+6)   -2 to the power of three

2.3    (20)     -2 to the power of three

2.3     (20)     -8

    46-8

      38

I really hoped this helped and if I got it wrong with the t just reply to me c:
