ra1l [238]3 years ago
7 0

Answer:

I need numbers to do a step by step

but the formula for the surface area of a cone.

Firstly, you work out the circle, pi x radius squared.

then you work out the cone

You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).

So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:

SA = πr2 + πrl

Anna11 [10]

Answer:

y(t) = \$1900*1.0375^t

Step-by-step explanation:

If y is the future value of the $1900 investment, in dollars, after t years at a rate of 3.75% per year, compounded annually. The exponential function that describes the relationship between the variables y and t is:

y(t) = \$1900*(1.0375)^t

This relationship means that for every year t, the amount y will increase by a factor of 1.0375.

sasho [114]

Lakisha's total job benefits per year are (D) $58,196.

<h3>What are employees' benefits?</h3>
  • Employee perks and benefits in kind are non-wage compensation provided to employees in addition to their regular income or salary.
  • A "salary package" or "salary exchange" arrangement is one in which an employee exchanges salaries for some other type of compensation.

To find  Lakisha's total job benefits:

If Lakisha's employer pays $2,150 in health insurance and $86 in life insurance per year, and she also gets $3,520 in paid time off per year, then Lakisha's total job benefits per year are equal to:

Total Benefits = Health Insurance + Life Insurance + Paid Time Off + Annual Gross Pay

  • Total Benefits= $2,150+$86+$3,520+12($4,370)
  • Total Benefits= $2,150+$86+$3,520+$52,440
  • Total Benefits=$58,196

Therefore,  Lakisha's total job benefits per year are (D) $58,196.
