please answerrrrr!!! im soo confused!!!
Answer:
97%
Step-by-step explanation:
If you get 100% on a test, you got all the answers correct.
It doesn't matter how many questions there are. If you got all of them correct, you get 100%.
What if you have 100 questions on a test?
If you got 85 questions correct, on a 100 question test, your grade would be 85%.
If you got 35 questions correct, on a 100 question test, your grade would be 35%.
If you got 98 questions correct, on a 100 question test, your grade would be 98%.
If you count 100 trees, and 97 of them were evergreen, the percentage of trees that are evergreen would be 97%.

true or false: to find the second derivative of a function take the derivative of the furst derivative if the function
Answer:
True
Step-by-step explanation:
The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).
I hope this is correct or at least helps incase I understood the directions above incorrect

The Venn diagram represents the Quantum Physics High School student body. Circle A represents all students enrolled in extracurricular activities. Circle B represents all female students. There are 117 female students enrolled in extracurricular activities, and the enrollment of the high school is 1,000 students. There are 450 male students. How many female students are not enrolled in extracurricular activities?
A.
117
B.
433
C.
550
D.
883
Answer:
total population of school = 1000
1000 - 450 males = 550 female students
550 - 200 females not in extra curriculars = 350 females in extra curriculars
350 + 90 males in extra curriculars = 440 total in extra curriculars
Circle A = 440
Circle B - overlap = 200 females not in extra curriculars
440 + 200 = 640
1000 - 640 = 370 students represented by the portion of the Venn diagram not in either circle

4(f-3)=20 I need help with this answer
Answer:
f=5
Step-by-step explanation:
4(f-3)=20 distribute
4f-12=20 add
4f-12+12=20+12... 4f=32 divide
4f/4=20/4..... f=5
Answer:
F=8
Step-by-step explanation:
DIVIDE BOTH SIDES BY 4
4(f-3)=20 Dividing 4(f-3) by 4 cancels out the 4 leaving it f-3
Dividing 20 by 4 =5
f-3=5 move the constant to the right (constant is the 5)
f=5+3 calculate
f=8
This is correct :)

if 4(x-1)=8(x-2),then x=
4(x-1)=8(x-2)
multiply the first bracket by 4
(4)(x)=4
(4)(-1)=-4
multiply the second bracket by 8
(8)(x)=8x
(8)(-2)=-16
4x-4=8x-16
move 8x to the other side ( in other words combine like terms)
sign changes from +8x to -8x
4x-8x-4=8x-8x-16
-4x-4=-16
move -4 to the other side
-4x-4+4=-16+4
-4x=-12
divide both sides by -4 to get x by itself
-4x/-4=-12/-4
x=3
answer:
x=3
Answer:
x = 3
Step-by-step explanation:
4( x - 1) =8
4x - 4 = 8
+ 4 + 4
4x = 12
x = 3
8 ( x - 2 )
8 ( 3 - 2 )
24 - 16
= 8
Using the relation f(x) = 2x + 16, what is the value of x if f(x) = 40?
Answer:
12
Step-by-step explanation:
40= 2x + 16
subtract 16 from both sides
24 = 2x
divide both sides by 2
12 = x

The polygons are similar. Find the value of the variable. Please HELPPPPPP!!!!
Answer:
C)
Step-by-step explanation:
Well, we know for the first polygon that the short side of the rectangle is 3 and for the second polygon the short side is 6, this means that for the second polygon, all sides will be double of the other side. 2 times the long side of the first rectangle is 18, this is why x = 18.
Hope this Helps!!! :)
Let me know in the comments if the answer was perfect or if I should change anything!
Answer:
C
Step-by-step explanation:
Because since 3 divided by 9 is 3 u have to double up the amount by 3 and that will be 18

If you earned $240 interest on a loan of $600 at an interest rate of 5%, how many years was the loan for?
Answer:
The loan was for 8 years.
Step-by-step explanation:
It is stated that you earned $240 interest on a loan of $600 at an interest rate of 5%.
Find the duration time by using the formula
I = Pit
Here:
'I' is the interest'P' is the total principal loan'i' is the rate of interest per year't' is the total time in yearssubstituting I = $240, P = $600 and i = 5%
I = Pit
t = I / Pi
= 240 / (0.05 × 600)
= 240 / 30
t = 8 years
Therefore, the loan was for 8 years.
