1 answer:

4 0

It would be 81 because in decimals the whole number is before the decimal point and since 6 is greater than 4 (1 through 4 round down and 5 through 9 round up)you would round up the 80 to make it 81

15% of what number equals 12?

dimaraw [331]

Percent means parts out of 100
15%=15/100=0.15
'of' means multiply

therefor
15% of x equals 12 means
0.15 times x=12
divide both sides by 0.15
x=80

the number is 80

Helpo me if you know the answers

Given:

The nth term of a number sequence is $n^2+2n$ .

To find:

The first 3 terms and the 10th term.

Solution:

We have, nth term of a number sequence.

$a_n=n^2+2n$

For n=1,

$a_1=(1)^2+2(1)$

$a_1=1+2$

$a_1=3$

For n=2,

$a_2=(2)^2+2(2)$

$a_2=4+4$

$a_2=8$

For n=3,

$a_3=(3)^2+2(3)$

$a_3=9+6$

$a_3=15$

For n=10,

$a_{10}=(10)^2+2(10)$

$a_{10}=100+20$

$a_{10}=120$

Therefore, the first three terms are 3, 8 and 15 respectively. The 10th term is 120.

Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a bag boy for $8 per hour. Due to his class

Bezzdna [24]

The answer is B.
He can't work more than 20 hours so t+b must be less than or equal to 20.
He has to earn $150 so it cannot be less than 150. Theoretically he could earn more, e.g doing 10 hours of each job which equals $230

Therefore t + b less than or equal to 20 15t + 8b greater than or equal to 150
