Mathematics

3 0

Answer:

  • 69.45 km/h

Step-by-step explanation:

  • Speed = Distance/Time
  • => Speed = 15 km ÷ 13/60
  • => Speed = 15 km ÷ 0.216
  • => Speed = 15 km/0.216
  • => Speed = 15 x 4.63/0.216 x 4.63
  • => Speed = 69.45 km/1 h (Approximate)

<u>Conclusion:</u>

  • Therefore, the speed is 69.45 km/h (Approximate)

Hoped this helped.

1.147 as a percentage​
Ratling [72]
Since a percentage is out of 100, simply divide 1.147 by 100 to get a percent. Dividing by 100 means moving the decimal two please to the left(once for each 0). So we should have 0.01147%

9 of the students in Sarah's grade like to watch football and 12 like to watch figure skating. 7 students like to watch both foo
madreJ [45]

Answer:

Step-by-step explanation:

Total for football: 9 +7

Total for figure skating: 12 +7

NEW Total for football: 16

NEW Total for figure skating: 19

The question says that 9 people like football

The question says that 12 people like to watch figure skating

The question also says that 7 people like to watch both, and because of that, you should add 7 to both 9 and 12, but keep the new numbers separated from each other. So once we know the sum of 9 +7 is 16, and 12 + 7 is 19, we can subtract the two numbers, and get 3 as the answer. Because you are counting the number of times that you have to travel up or down to the other number, and so if you are on a set of stairs that go up to the 16 level and you are on the 14th level, you need to travel up 2 sets of stairs to get to level 16.

Hope that example helps and can help in the future with other problems!

What is the answer for 4a+2b=16
Dmitry_Shevchenko [17]
First, move all terms containing a to the left, all other terms to the right.

Add '2b' to each side of the equation.
4a + -2b + 2b = 16 + 2b

Combine like terms: -2b + 2b = 0
4a + 0 = 16 + 2b4a = 16 + 2b

Divide each side by '4'.
a = 4 + 0.5b

Answer
 

= 4 + 0.5b
