Answers

Answer 1

Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:P = Principal / initial amountR = rate of interest per cent per yearT = number of yearsA = final amount at the end of T yearsThen:A = P*(1 + R/100)^2In our example:P = £12000R = 1.5 per cent per yearT = 2 yearsThus:A = 12000*(1 + 1.5/100)^2   = 12000*(1 + 0.015)^2   = 12000*(1.015)^2    = 12000*(1.030225)    = 12362.7Value of investment after two years = £12362.7

20 POINTS!! What would be the first step to solve this equation?
m - 13 = 24

A. Subtract 13 from both sides
B. Add 24 to both sides
C. Add 13 to both sides
D. Divide by 13 on both sides

Answers

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37

~

what is something you multiply and get -24 but when you add you get -10

Answers

the numbers are 2 and -12

2 x -12 = -24
2 + -12 = -10

Answer:

-7(2)-10 = -24

Step-by-step explanation:

-7(2) = -14(+-10) = -14-10=-24

the table below shows the salary that ellen earned at her job based on her years of experience.

Which explicit formula can be used to determine the salary, f(n), that Ellen earned with n years of experience?

A: f(n)=4,350n+31,900
B: f(n)=4,350n+14,500
C: f(n)=725n+31,900
D: f(n)=725n+29,009

Answers

Answer:

Step-by-step explanation:

Find the difference between year 4 and year 5 salary.

32,625 - 31,900 = 725 (rate of change)

Multiply 4 x 725 then subtract that number from 31,900 to find out base salary

4x 724 = 2900

31,900 - 2,900 = 29,000

That's the constant.

So,

f(n) = 725n + 29,000

A comparison of the measures of central angles and inscribed angles of circles to their intercepted arcs are listed in the tables below. Based on the data in the tables, which conjecture about inscribed and central angles is true?.

Answers

A central angle means an angle that is at the center of a circle and whose legs are intersecting the circle.

What is a central angle?

Your information is incomplete as the data is not given. Therefore, an overview will be given.

Central angles are shaped by an arc between the two points. When a central angle and the inscribed angle intercept the same arc, then the central angle would be the double of the inscribed angles while the inscribed angle will be half of the central angle.

What is the sale price for a beach umbrella with a regular price of $43.59 which is on sale for 20% off?

Answers

Answer:

$34.87

Step-by-step explanation:

20% of $43.59

[tex]\frac{20}{100} X \frac{43.59}{1}[/tex] = [tex]\frac{1}{5} X \frac{43.59}{1}[/tex] = [tex]\frac{43.59}{5}[/tex] = $8.718

Therefore the price is, $43.59 - $8.718 = $34.87

Answer:

The answer is $34.87

Step-by-step explanation:

$43.59- 8.72=$34.87

20% of $43.59 is $8.72

So, your answer will be $34.87

$43.59- 8.72=$34.87
