Answer:

  76%

Step-by-step explanation:

Let f represent the score on the final. Then Inara wants the final grade to be ...

  0.25·74 +0.20·99 +0.55·x ≥ 80

  38.3 +0.55x ≥ 80

  0.55x ≥ 41.7

  x ≥ 41.7/0.55 ≈ 75.82

Inara needs a final exam grade of 76% or better to earn at least 80% in the course.

We want to place a bench measuring 7.05 feet in the center of a platform that is 40.75 feet long. What is the distance from each
alexandr402 [8]

Answer:  The distance from each side of the bench to the edges of the platform = 16.85 feet.

Explanation:

Length of platform = 40.75 feet

Length of bench  = 7.05 feet

Let the distance from each side of the bench to the edges of the platform be x

So, it becomes x+7.05+x = 40.75

⇒2x+7.05= 40.75

⇒2x = 40.75- 7.05

⇒x = 33.7

⇒x=\frac{33.7}{2}

⇒x= 16.85 feet .

So, the distance from each side of the bench to the edges of the platform = 16.85 feet.

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
