Answer:

80 centimeters taller

Step-by-step explanation:

First, convert Alex's height from meters to centimeters by multiplying by 100 because there are 100 centimeters in one meter to get 160 centimeters. Now multiply 160 centimeters by 1.5 to get Noah's height, 240 centimeters. Finally, since we need to find their difference in height, subtract Alex's height of 160 centimeters from Noah's height of 240 to get 80 centimeters.

gtnhenbr [62]

Answer:

∠JKM = 42°

Step-by-step explanation:

Since M is in the interior of ∠JKL, then

∠JKM + ∠MKL = ∠JKL ← substitute values

∠JKM  + 42 = 84 ( subtract 42 from both sides )

∠JKM = 42°

Round 478.54 to the nearest tenth
Schach [20]
A tenth is the number that occurs after the decimal
If the number after the tenth is five or higher, then you round up
If the number after the tenth if four or lower, then the tenth stays the same value as it is
In this case, the Ume after the tenth is exactly four, so the value of the tenth stays the same
So your answer is 478.5

What is 6 kg 650g to the nearest 1/2kg
zysi [14]
Given:
6kg 650g
1/2 kg

1/2 kg is equal to 500 grams

1 kg = 1000 grams

We need to convert these figures from kg to g.

6 kg * 1000g/kg = 6*1000g = 6,000 g

6,000 g + 650 g = 6,650 g

6,650 g ÷ 500 g = 13.3 round off to 13

13 * 500 g = 6,500

6 kg 650 g is nearest to 6,500 g.

vagabundo [1.1K]

Answer:

B) 0.57

Step-by-step explanation:

Let's define:

  • A: the home has a laptop
  • B: the home has a desktop computer.

Data

  • P(B) = 0.82
  • P(A∩B) = 0.47

We want to find the probability that a home has a laptop given that it has a  desktop computer, that is, P(A|B).

P(A|B) = P(A∩B)/P(B) = 0.47/0.82 = 0.57
