Answer:

B $45.26

Step-by-step explanation:

After 10 years

Emily will have 500 * 1.045^10 = $795.26

Erica will have 500 + 10*0.05*500 = 500 * 1.5 = 750$

Emily will have $45.26 more.

George is twice as old as Edward, and Edward's age exceeds Robert's age by 4 years. If the sum of the three ages is at least 56
marshall27 [118]

Answer:Robert's minimum age is 11 years.

Step-by-step explanation:

Let x represent George's age.

Let y represent Edward's age.

Let z represent Robert's age.

George is twice as old as Edward. It means that

x = 2y

Edward's age exceeds Robert's age by 4 years. It means that

z = y - 4

If the sum of the three ages is at least 56 years, it means that

x + y + z ≥ 56 - - - - - - - - - - 1

Substituting x = 2y and z = y - 4 into equation 1, it becomes

2y + y + y - 4 ≥ 56

4y - 4 ≥ 56

4y ≥ 56 + 4

y ≥ 60/4

y ≥ 15

z = y - 4 = 15 - 4

z ≥ 11

What is 12.496 rounded to a whole number. what is 2.90 rounded to a whole number
otez555 [7]
A whole number is a number that is whole as in 1,2,3,4,etc, they don’t have decimals. To find the whole number for these questions you must look at the places (hundreds, thousands, ten thousands.) I was always told a trick which is 4 or less let it rest, 5 or more let it sore. (Basically if it’s less than 4 then decrease it, if it’s higher than increase it.)

12.496 = 13
2.90 = 3

Your answers are 13 and 3.
