20% of 90, and i have to show workings out

Answers

Answer 1

Answer: 10% of 90 is 9, 10% times 2 is 20%, therefore 20% of 90 is 2*10% of 90, or 18

Answer 2

Answer: It helps to know that 10% of anything is the number divided by 10. So 10% of 90 = 9. As it is 20% and not 10, just do it twice and add them together :) OR just times it by 2 which is much easier. So 9 x 2 = 18.

10% of a number is the number divided by 10.
5% of a number is the number divided by 10 THEN divided by 2.
1% of a number is the number divided by 100.

F(x) 5,450(1.024)^x The domain for the function that represents the amount of time the money will be in the college fund is _ the range for the function that represents the amount of money that is in the college fund is _

Answers

Answer:

1.) Domain X = all positive real numbers

2.) Range: F(x) > = 5450

Step-by-step explanation:

Given that

F(x) = 5,450(1.024)^x

Where the domain is the independent variable X and the range is the dependent variable Y or F(x)

Since the domain for the function represents the amount of time the money will be in the college fund, time cannot be negative, it will always be positive.

Therefore, domain x will be all positive real numbers.

The least domain x = 0

Substituting domain into the equation will give us a range of value:

F(x) = 5450 × ( 1.024 )^0

F(x) = 5450 × 1

F(x) = 5450

That is, the least value of range = 5450

Therefore, Range will be F(x) greater than or equal to 5450.

F(x) > = 5450

Answers

Answer:

v=-143

Step-by-step explanation:

45-v=188

-v=188-45

-v=143

v=-143

Answer:

Step-by-step explanation:

45 - v = 188

-v = 188 - 45

-v = 143

v = -143
