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!!

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?​

Answers

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

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

Answers

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.

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.

Answers

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

what is your solution to this equation ? 2x + 10 =28

Answers

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

Can the sides of a triangle have lengths 3, 7, and 15?

Answers

No because the positive length of a triangle would be 3, 7, 7 because the third side length must be greater than 4 and smaller than 8 so there for 7 would fit. So your answer is no.

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
