If 45% of a number n is 225 what is 75% of n

Tpy6a [65]

75% of n is 375.

Step-by-step explanation:

Given,

45% of a number n = 225

We will find n first.

$\frac{45}{100}n=225\\0.45n=225$

Dividing both sides by 0.45

$\frac{0.45n}{0.45}=\frac{225}{0.45}\\n=500$

Now we have to find 75% of n.

75% of n = $\frac{75}{100}*500=75*5$

75% of n = 375

75% of n is 375.

Answer:

n= -3.5

Step-by-step explanation:

n/7 - 12 = 5n +5

+12 +12

n/7 = 5n+17

*7 *7

n = (5n+17)*7

n = 35n + 119

-35n -35n

-34n = 119

/-34 /-34

n = -3.5

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?

Stels [109]

Answer:

C) $P(E) = \frac{3}{6}$

The probability that Mae will roll an odd number

$P(E) = \frac{3}{6}$

Step-by-step explanation:

Step(i):-

Given that Mae has a number cube with 6 sides that are numbered 1 through 6.

n(S) = { 1,2,3,4,5,6,} = 6

Let 'E ' be the event of odd numbers

Mae will roll an odd number

n(E) = {1, 3, 5} = 3

Step(ii):-

The probability that Mae will roll an odd number

$P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}$

$P(E) = \frac{3}{6}$
