A high school teacher gives three regular exams during a semester and one final exam at the end of the semester. A student’s final grade is found by taking of the student’s three regular exam scores and then adding 40% of the student’s final exam score. Sophia earned scores of 78, 92, and 80 on the three regular exams and a score of 90 on the final exam. What is Sophia’s final grade?

Answers

To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.

A number,y,is 2 more than 3 times another number,x, the sum of the 2 numbers is 26. What are the two numbers?

Answers

y = 2 + 3x
x + y = 26

Substitute:
x + (2 + 3x) = 26
4x + 2 = 26
4x = 24
x = 6

6 + y = 26
y = 20

The area of a rectangular trampoline is 135 ft. The length of the trampoline is 6 ft
greater than the width of the trampoline. This situation can be represented by the
equation w2 +6w
135 = 0.
What is the width of the trampoline, in feet?
5 feet
15 feet
6 feet
9 feet

Answers

The width of the given trampoline is 9 feet, and which area is 135 square feet.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The equation w² +6w -135 = 0 can be factored as (w+15)(w-9) = 0.

Therefore, the solutions for w are w = -15 or w=9.

Since the width of the trampoline cannot be negative, we can conclude that the width of the trampoline is 9 feet.

To confirm this, we can calculate the length of the trampoline using the given information that the length is 6 feet greater than the width:

length = width + 6 = 9 + 6 = 15 feet

Then we can verify that the area is indeed 135 ft²:

area = length x width = 15 x 9 = 135 ft²

Therefore, the width of the trampoline is 9 feet.

8/9 divided by 5? :’)

Answers

Answer:

8/45 or 0.177...... (the seven continues forever).

Step-by-step explanation:

8/9 ÷ 5

First, turn 5 into a fraction. That will be 5/1

8/9 ÷ 5/1

When you're dividing fractions, you flip the second fraction and turn the division sign to a mutiplication sign

8/9 ÷ 1/5

8/9 * 1/5

Now you multiply. We will multiply the numerator and then the denominators through since there are no common factors.

8 * 1/9 * 5

8/45

Answers

Answer:

a = 8, b = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given the exponential function

f(x) = a[tex]b^{x}[/tex]

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

a = 8

f(x) = 8[tex]b^{x}[/tex]

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

[tex]\frac{18}{8}[/tex] = b² , that is

b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )

b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]

Thus

f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

An Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?

Answers

Since it is 7 weeks and they order 15 pounds every two weeks they will order 3 times. 15 times 3 is 45. Your answer is 3 bags
2 goes into the 7 weeks 3 times with a remainder of a week until they buy another 15 pounds of onions. So 15 x 3 = 45 pounds. They’ll have 45 pounds of onions in 7 weeks as on the 8th week they’ll buy another 15 pounds but the question only wants to know by the 7th week.
