Option A : a+o = 92 , 4a+2o = 284 is the right answer
Step-by-step explanation:
Let o be the number of oranges sold on Friday and
a be the number of apples sold on Friday
So,
A total of 92 was sold on Friday will yield the equation
On Saturday,
4 times the number of apples = 4a
2 times the number of oranges = 2o
So,
Hence,
The system of equations is:
Option A : a+o = 92 , 4a+2o = 284 is the right answer

Answer: one of ten or one over two
Step-by-step explanation:
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.
Answer:
Number of adults that attended the show = 400
Number of children that attended the show = 359
Total people who attended the show = 759
Step-by-step explanation:
Total earned = 15,385
Adults = $25
Children = $15
Let
Adults = A
Children = C
The number of adults who attendee the show was 41 more than the number of children who attended the show
A = C + 41
25A + 15C = 15,385
Substitute
A = C + 41
25(C+41) + 15C = 15,385
25C + 1,025 + 15C = 15,385
40C + 1,025 = 15,385
40C = 15,385 - 1,025
40C = 14,360
Divide both sides by 40
C = 14,360 / 40
= 359
C = 359
Substitute C = 359 into
A = C + 41
A = 359 + 41
= 400
A = 400
Number of adults that attended the show = 400
Number of children that attended the show = 359
Total people who attended the show = 759
Answer:
= $ 4344.05
Step-by-step explanation:
Using the formula
A = P (1 +r/n)^nt
Where A is the amount accumulated, P is the principal amount, n is the number of interest periods, t is the time taken in years.
A = $4369.20
r = 0.033
n = 4
t = 21/12
Therefore;
$4369.20 = P ( 1 + 0.033/4)^ (21/12×4)
$4369.20 = P (1.000825)^7
$4369.20 = 1.005789 P
P = $4369.20/1.005789
<u> = $ 4344.05</u>
