A history class is made up of 12 tenth graders and 9 eleventh graders. The tenth graders
averaged 77 on the midterm exam, and the eleventh graders averaged 91 on the midterm
exam. What was the average grade on the midterm exam for the entire class?
Answer:
They average 84%
Step-by-step explanation:
Just add 77 and 91 then divide it by 2. Hope this helps.
Answer:
83 is the correct answer if you just do it by adding 91 and 77 then diving it by 2 you would get 84 that is not what answer they are looking for. Took the test 83 is what they are looking for they want you to do the work.
Step-by-step explanation:
Tenth graders 12*77= 924
Eleventh graders 9*91= 819
924+819= 1,743
12 tenth graders and 9 eleventh graders
12+9 = 21
1,743/21 = 83

Determine whether each pair of figures is similar. If so, write the similarity statement and scale factor. If not, explain why. Number 1 and 2 on the second part.
9514 1404 393
Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.

Determining Median is super easy!
1. Order the numbers, in ascending order.
8, 11, 11, 12, 13, 15, 16, 16, 18, 21
2. Cross off one number from both ends until you reach the middle number, whether you're left with one or two.
11, 11, 12, 13, 15, 16, 16, 18
11, 12, 13, 15, 16, 16
12, 13, 15, 16

Find the altitude of the triangle.
30 degrees
Hypotenuse of 14
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x

Consider the function f(x) = x^2 - 10x - 24. Given that one of the solutions of the function is x = -2, what is the other solution of the func
Answer:
5
Step-by-step explanation:
You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.
It's the quadratic formula
x = [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]
The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.
a is the coefficient of the first term in the expression, b is the second and c is the third.
so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as
[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]
and
x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]
The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.
