Answer:

7.5 mins.

Step-by-step explanation:

1.5/1 = 7.5/5

It takes a shark 7.5 (7 1/2) minutes to swim 5 km.

oksano4ka [1.4K]

Answer:

8542

Statement

1.It is a four digit number

2.The tens are double the ones

3.The thousands are double the tens

4.The sum of the digits is nineteen

Step-by-step explanation:

It is a four digit number

lets take 4 digit number-ABCD

The tens are double the ones

C=2D-----------------------------1

The thousands are double the tens

A=2C-------------------------------2

According to equation 1 and 2

A=4D

If we take

D=1,2

Possible number

4B21 OR 8B42

The sum of the digits is nineteen

I use hit and trial method

4B21- If I take B is maximum

4+9+2+1\neq 19

8B42- If, i try to find value of B

8+B+4+2=19---------------------3

14+B=19\\B=19-14\\B=5

So the unknown number is-  8542

Find the probability of rolling a 2,3, or 4 on the number cube
kolezko [41]
Well, if you wanted the answer, it is provided in the picture that you yourself have uploaded. However, if need more clarification on how to find that answer. Here I go. 

So, you can ask yourself, how many numbers are on the cube? 6, from 1-6. So there are 6 possible outcomes. Now between the numbers 1, 2, 3, 4, 5, 6, how many are the numbers 2, 3, or 4? There are 3, so it is 3/6, 1/2, 50%, or 0.5.
