Answer:
Wrong problems = 32
Step-by-step explanation:
Total no of problems = 200
Charlotte earned a grade of 84% on her multiple-choice.
Correct problems,
Wrong problems = 200 - correct problems

= 32
Hence, there are 32 problems on the final exam Charlotte get wrong.
Answer:
+3/2 (Answer B)
Step-by-step explanation:
If the slope of a given line is m, then the slope of any line perpendicular to this given line is the negative reciprocal of the slope of the latter:
-1
------------ = +3/2 (Answer B)
-2/3
Answer:
X=3/2 and 2/3
Step-by-step explanation:
6x^2 - 13^x + 6= 0
6x^2 - 4x - 9x + 6=0
By factorising...
2x(3x - 2) - 3(3x - 2)=0
(2x - 3) (3x - 2)=0
2x - 3=0
2x=3
X=3/2
3x - 2=0
3x=2
X=2/3
Hence, X=3/2 and 2/3
Answer:
3%
Step-by-step explanation:
Erin earned 6191.50 -6100 = 91.50 in interest in 6 months on a 6100 principal. Then the annual interest rate is ...
I = Prt
r = I/(Pt) = 91.50/(6100·6/12) = .03 = 3%
The interest rate was 3%.
Answer:
4
Step-by-step explanation:
ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.
Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.
EF ≅ BC
x² + 8x = 48
x² + 8x − 48 = 0
(x + 12) (x − 4) = 0
x = -12 or 4
Since x can't be negative, x = 4.
