Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
Answer:
750 rupees is used to make shirt
250 rupees is profit
Step-by-step explanation:
If the retailer sold the shirt for 1000 rupees and got 25% profit then that means 1/4 is profit and 3/4 is how much the retailer spent to make the shirt.
So 1000 times 3/4 is 750 which is how much the shirt really cost and
1000 times 1/4 is 250 and that is the retailers profit.
The ratio of the given legs of ΔFGH is 3:4, so we know this is a 3:4:5 triangle and the hypotenuse is 5/3 times the shortest leg. Then in similar ΔJKL, the hypotenuse will be (5/3)*2.4 m = 4 m. (selection B)
Answer:
The answer is 35 plants.
Step-by-step explanation:
The ratio of tomato plant to that of pepper plant = 2:5
Let x be the number of pepper plants for 14 tomato plants.
Now, according to the question:
2:5 = 14:x
14×5 = 2x
x = 70/2 = 35 plants.
Answer:
39 degrees
Step-by-step explanation:
The angle of a straight line is 180 degrees. This is constant and will never change. You will add 57 and 84 to get 141 degrees for <LMP. Take 180-141 to get 39 degrees for <PMN
