What number is 30% of 90​

Mathematics
2 answers:
Alika [10]3 years ago
7 0

Answer:

27

Step-by-step explanation:

30% is 100%, subtracted by 70%. All we have to do is convert 70% to a decimal. To do that, we divide 70% by 1.

70% ÷ 1 = 0.7

Now we multiply 90 by 0.7.

90 × 0.7 = 63

To get your answer, we subtract 90 by 63.

90 - 63 = 27

This is your answer, I hope I helped!

A sequence is represented by the formula an=-5+a(n-1). If a4 = 20, what is the 6th term in the sequence?
Citrus2011 [14]

Answer:

<u>10</u>

Step-by-step explanation:

Formula :

  • aₙ = -5 + aₙ₋₁

Finding a₅ :

  • a₅ = -5 + a₄
  • a₅ = -5 + 20
  • a₅ = 15

Finding a₆ :

  • a₆ = -5 + a₅
  • a₆ = -5 + 15
  • a₆ = <u>10</u>

Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found. A squirrel hid 40 nuts all together.
koban [17]

Answer:

15 nuts do not get found.

Step-by-step explanation:

Given that Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found.

Total number of nuts squirrel had hidden = 40

Proportion of nuts not found to total = 3/(3+5) = 3/8

Hence out of 40, nuts not found =3/8(40) = 15 nuts.

15 nuts would not be found and 25 nuts would be found if squirrel had hidden in total 40 nuts.

This is because the proportion of found:unfound = 5:3

Hence 25:!5 =5:3 satisfies this

15 nuts are not found.
