Answer:
D
Step-by-step explanation:
check each child answer and multiply by 4.50
check each adult answer and multiply by 6.00
add both answers up
and see which one it is
its not A, B, or C
Answer:
D
Step-by-step explanation:
x-number of children's tickets sold
y-number of adult's tickets sold
x+y=520=>x=520-y
4.5x+6y=2 707.5
45x+60y=27 075
45(520-y)+60y=27 705
15y+23 400=27 705
15y=3 675
y=245=>x=520-y=520-245=275
The zeros of a quadratic function are 6 and -4. Which of these choices could be the function?
OA.
AX) = (x - 5)(x-4)
OB
f(x) = (x + 6)(x-4)
O C.
Ax) = (x+6)(x + 4)
OD
Ax) = (x - 6)(x+4)
Answer:
OD
f(x)= (x-6)(x+4)
because (x-6)=0
x=6
and. (x+4)=0

Answer:
i believe x=9
Step-by-step explanation:
I took the answer, (28) and subtracted 10 which got me 18. then all I had to do was divide 18 by 2 to get x, which is 9. hope this helps :)
Answer:
x = 9
Step-by-step explanation:
We have: 2x + 10 = 28
Subtract 10 from both sides: 2x = 18
Divide both sides by 2: x = 9

The scale of a map is 1:4 000 000. Hint: 1:4 000 000 means that 1cm on the map = 4 000 000 on the ground. The distance between Leeds and London on this map is 8.125cm. Calculate the actual distance between Leeds and London. Give your answer in kilometres.
Answer:
325 km
Step-by-step explanation:
Given the scale :
1 : 4 ,000, 000
1cm measure in map = 4000000 on the ground
From the map :
Distance between Leeds and London = 8.125 cm
The actual distance on ground can be calculated thus :
1cm = 4,000,000
8.125cm = x
Cross multiply
x = 32500000 cm
Converting to kilometers :
1 km = 100,000 cm
x = 32500000
Cross multiply
100,000x = 32500000
x = 32500000 / 100000
x = 325
Hence, actual distance between Leeds and London is 325 km

Answer:
15. 1.125 hours = 1 hour 7 minutes 30 seconds
17. 3840 cal
18. 60 g
Step-by-step explanation:
15.
8 miles is to 3 hours as 3 miles is to x hours
8/3 = 3/x
8x = 3 * 3
8x = 9
x = 1.125
Answer: 1.125 hours = 1 hour 7 minutes 30 seconds
17.
1/2 avocado is to 160 cal as 12 avocados are to x cal
(1/2)/160 = 12/x
(1/2)x = 12 * 160
x = 24 * 160
x = 3840
Answer: 3840 cal
18.
We need the same units. We convert 2 1/2 cups into tablespoons.
1 cup = 16 tablespoons
2 1/2 cups = 2 1/2 * 16 tablespoons = 2.5 * 16 tablespoons = 40 tablespoons
Now we start the proportion.
1.5 g to 1 Tbsp is as x is to 40 Tbsp
1.5/1 = x/40
x/40 = 1.5
x = 1.5 * 40
x = 60
Answer: 60 g

class A has 11 pupils and class B has 14 pupils. Both classes sit the same maths test. the mean score for class A is 32. The mean score for class B is 38. What is the mean score(rounded to 2DP) in the maths test across both classes?
Answer:
35.36
Step-by-step explanation:
For Class A
Class A has 11 pupils
The mean score for Class A is 32.
The total score of the students =
Mean score × Number of pupils
= 32 × 11
= 352
For Class B
Class B has 14 pupils. The mean score for class B is 38.
The total score of the students =
Mean score × Number of pupils
= 38 × 14
= 532
Total number of pupils for both classes = (11 + 14)pupils
= 25 pupils
Total score for both class = 532 + 352
= 884
The mean score(rounded to 2DP) in the maths test across both classes is calculated as:
Total score of both classes÷ Total number of pupils
884 ÷ 25
35.36

Answer:
The answer is B!!
Step-by-step explanation:
What do we know given from the statement above the photo? We are told <Q is congruent to <S, and QR is congruent to SR. So by given that, we have an angle (angle Q or angle S), a side (side QR or SR), and another angle (angle R), so we have ASA. I hope this helps!!
Answer:
b
Step-by-step explanation:
From the comment above the photo, what do we know? We are advised that <Q is <S, and that QR is SR-compatible. We've got a corner (angle Q or angle S), a line (side QR or SR), and a separate angle (angle R), so we have ASA. I hope that's good!!
A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar.
y=-x^2+90x-454
9514 1404 393
Answer:
$1571
Step-by-step explanation:
If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...
ymax = $1571
The maximum profit the company can make is $1571 at a selling price of $45 each.
_____
The function can be written in vertex form as ...
y = -(x^2 -90x) -454
y = -(x^2 -90x +45^2) -454 +45^2
y = -(x -45)^2 +1571
Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
