Can three line segments with the given lengths form a right triangle?
musickatia [10]

Answer:

Yes

12, 35, 37

16, 30, 34

20, 21, 29

No

18, 24, 42

Step-by-step explanation:

Required

Determine which length form a right triangle

To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths

So:

(1) 12, 35, 37 --- Yes

37^2 = 35^2 + 12^2

1369 = 1225 + 144

1369 = 1369

(2) 16, 30, 34 --- Yes

34^2 = 16^2 + 30^2

1156 = 256 + 900

1156 = 1156

(3) 18, 24, 42 --- No

42^2 =18^2 + 24^2

1764 =324 + 576

1764 =900

1764 \ne 900

(4) 20, 21, 29 -- Yes

29^2 = 20^2 + 21^2

841= 400 + 441

841= 841

A pineapple is 7 times as heavy as an orange. The pineapple also weighs 870 grams more than the orange.
Kazeer [188]
Let's say that the weight of the orange is x and the weight of the pineapple is y.
The weight of the pineapple is 7 times that of the orange, so
y = 7x.
Also, y = x + 870.
Therefore, 7x = x + 870.
If we take away x from both sides, we get 6x = 870
If we divide both sides by 6, we get x = 145.
Therefore, the weight of the orange is 145 g.
Also, 145 + 870 = 1015.
So the weight of the pineapple is 1015 g.

To convert grams into kilograms, they must be divided by 1000.
Therefore, the weight of the orange in kilograms is 145/1000 = 0.145 kg
And the weight of the pineapple is 1015/1000 = 1.015 kg.

Answers:
a. 145g for the orange and 1015g for the pineapple.
b. 0.145kg for the orange and 1.015kg for the pineapple.
