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 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.

can i be brainiest...
Answer:
the answer is 14y
Step-by-step explanation:
this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.

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]

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

What is the value of x in the equation 3/4 x + 24 = x − 12 ?
Answers
Answer:
x = 144
Step-by-step explanation:
3/4x + 24 = x - 12
3/4x - x = -12 - 24
3/4x - 4/4x = -36
-1/4x = -36
x = -36/-1/4
x = 144

What is your question?
Mrs. brown has 8 more boys than girls in her class and has a total of 26 students. Determine how many girls and boys are in the class.
May I please get some help ASAP?
Answers
Answer:
There are 9 girls in the class and 17 boys in the class
Step-by-step explanation:
Set up a system of equations where b is the number of boys and g is the number of girls
b + g = 26
b = g + 8
Solve by substitution by substituting g + 8 as b into the top equation
b + g = 26
(g + 8) + g = 26
2g + 8 = 26
2g = 18
g = 9
So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:
9 + 8
= 17
So, there are 17 boys.
There are 9 girls in the class and 17 boys in the class.
since he has 8 more boys than girls.
The amount of girls 9
More than 8 so
9+8=17
So 17 plus the 9 girls would be 26 students
