mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500 worth of goods for a certain month calculate mary's gross salary for that particular month

Answers

Answer:

3300

Step-by-step explanation:

Formula

Gross Salary = Basic + Commission

Givens

Basic = 3000

% = 12%

Solution

Gross = 3000 + 12/100 * 2500

Gross = 3000 + 30000/100

Gross = 3000 + 300

Gross = 3300

==========================================

Explanation:

Here's a slightly more detailed breakdown of what's going on

3x + 2y = 15 ... start with the first equation

3x + 2( y ) = 15 .... the parenthesis don't change the expression

3x + 2( 3x+5) = 15 ... replace y with 3x+5; since y = 3x+5

From here, you solve for x like you would any other single variable equation. Once you know x, you can determine y through y = 3x+5.

Airplanes use radar (radio waves) to measure distances.

The plane is at a height of 5200 m. The airport is 10.2 km away.

How far does the plane need to travel before it lands?


a) 11.4 km

b) 10.4 km

c) 5200 km

d) 10.2 km

Answers

Answer:

10.2 km

Step-by-step explanation:

I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

D is the answer, hope it helped

Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =

Answers

The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.

The equation is  

d

=

12.5

×

t

Explanation:

To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:

For example

25

miles

÷

2

hours

=

12.5

miles

hour

A direct proportionality will always result in an equation that resembles this:

y

=

k

x

where  

y

and  

x

are the related quantities and  

k

is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

1. Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year
Use an exponential function to find the annual sales after 7 years.

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.

Answers

Answer:

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Step-by-step explanation:

Let

Mass of brown eggs = x

Mass of white eggs = y

3y + 2x = 13 (1)

5y + 4x = 24 (2)

Multiply (1) by 5 and (2) by 3 to eliminate y

15y + 10x = 65 (3)

15y + 12x = 72 (4)

Subtract (3) from (4)

12x - 10x = 72 - 65

2x = 7

x = 7/2

x = 3.5

Substitute x = 3.5 into (1)

3y + 2x = 13 (1)

3y + 2(3.5) = 13

3y + 7 = 13

3y = 13 - 7

3y = 6

y = 6/3

y = 2

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Answers

Answer:

Step-by-step explanation:

1) Add 7 to both sides.

[tex]b = 12 + 7[/tex]

2) Simplify 12 + 7 to 19.

[tex]b = 19[/tex]

Therefor the answer is, b = 19.

Answer:

Sample Response

Step-by-step explanation:

Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.
