24 is 60% of what number?

Answers

60% of number = 24

60% is given by multiplying by 0.6

number x 0.6 = 24

number = 24 / 0.6

number = 40

24 is 60% of the number 40.

To find the number that 24 is 60% of, we can set up a proportion. Let's assume the unknown number is represented by "x". The proportion would be:

24/x = 60/100

To solve for x, we can cross-multiply:

60x = 24(100)

Simplifying the equation:

60x = 2400

Dividing both sides by 60:

x = 2400/60

x = 40

Therefore, 24 is 60% of 40.

To verify this, we can calculate 60% of 40:

60% of 40 = (60/100) (40) = 0.6(40) = 24

So, indeed, 24 is 60% of 40, and our solution is consistent.

Which expression could be used to solve the problem? Gem counted 54 wheels on 3 semitrucks. The same number of wheels were on each semitruck. How many wheels were on each semitruck? A. B. 54 • 3 C. 54 – 3 D. 3 + 54

Answers

Here, we could simply divide the values. 

54/3 = 18

So, the correct answer is :-

54 divided by 3
54/3 = 18
which concludes 18 wheels on one semitruck. ( seems a lot for me :) )

49w^2-4=0. Simplied fraction?

Answers

Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.
