Answer:

for the first picture: 2.16

Step-by-step explanation:

12% of 18 is 2.16:

-convert 12 % to a decimal so 0.12 times 18

also, 12 % percent is 0.12 as a decimal because you move the decimal 2 places to the left to get .12

- multiply 0.12 times 18 to get 2.16 as the answer

I hope this helped for the first pic!

If n is a term of the sequence 14, 8, 2, -4, …, which expression would you give the value of n?
Ipatiy [6.2K]

Answer:

-6n+20

Step-by-step explanation:

The given  term of sequece is  14, 8, 2, -4, …,

Here the first term is 14 and then the terms are decreasing by 6 each time  because 14-8=8-2=...=6

As we know that the nth term of the sequence is given by the formula

t_n=a+(n-1)d\\\text{Substitute the values we get}\\t_n=14+(n-1)(-6)\\t_n=14-6n+6\\t_n=20-6n\\

If n is a term of the given sequence sequence, then its value is -6n+20

Which ratio is greater, 4:5 or 3:4?
Grace [21]
4:5
explanation-

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.
