Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary of $750 per week. How much did she earn last week if she sold $4,000 in electronic merchandise? Round to the nearest cent. I look on the answer key and it was 1,076.25. But can somebody explain why or the step?

Answers

Percentage of commission earned by Danielle on everything she sells = 7.25%
Amount of money she earns as the base salary per week = $750
Amount of money for which she sold electronics merchandise in a week = $4000
Then
Amount of commission receiver by her = 4000 * (7.25/100)
   = 40 * 7.25
   = 290
So she earns a commission of $290 by selling electronics merchandise in a week.
Then
Total amount of money earned by Danielle = (750 + 290) dollars
   = 1040 dollars
Then Danielle earned a total of $1040 in last week. The answer that you have given is not correct. Please check the procedure.

A coyote weighs 11.3 pounds.convert the coyote's weight to ounces

Answers

The coyote's weight is 180.8 ounces

Further explanation

The coyote's weighs 11.3, convert this to ounces

We know that:

$\boxed {1 pounds = 16 ounces\ }$

x= coyote's weight in ounces

$\boxed {(16 ounces)/( 1 pound)= (x)/(11.3 pounds)\ }\n \boxed {x = 11.3 pounds *\ 16 ounces\ }\n \boxed {x= 180.8 ounces\ }$

In converting unit of measurement, we can use this three step:

write the conversion in fraction
multiply
cancel any unit that are both top and bottom

There are 16 ounces in a pound, so just multiply 11.3 times 16. That will get you 180.8 ounces.

Solve the quadratic equation by completing the square. 2x2 + 3x - 4 = 0

Answers

Answer: x = 0

Step-by-step explanation:

4 + 3x - 4= 0

3x=0 (divide both sides by 3)

x= 0/3

x = 0

Step-by-step explanation:

$2 {x}^(2) + 3x - 4 = 0 \n 16 {x}^(2) + 24x - 32 = 0 \n 16 {x}^(2) + 24x + 9 = 41 \n {(4x)}^(2) + 2 * 4x * 3 + {(3)}^(2) = 41 \n {(4x + 3)}^(2) = 41 \n |4x + 3| = √(41) \n 4x + 3 = + - √(41) \n 4x = - 3 + - √(41) \n x = ( - 3 + - √(41) )/(4)$

An auto mechanic charges $50 to diagnose a problem and $25 per hour to repair the problem. If x represents the total number of hours worked and y represents the total charges, which equation represents this situation?A. y = 25x + 50
B. y = 50x + 25
C. y = 50x - 25
D. y = 25x - 50

Answers

D because 25 is the number of hours meaning that it will me your x and -50 because your giving away $50

We know the width maybe 22ft and at its widest.

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.

With triangles;

The number of triangles is always 2 less than that that of its sides.

= 3 triangles + 2 = 5 sides.

The sum of interior angles

(n-2) x 180 = 540 degree

5-2 x 180

To determine the amount of sides; we remember

(n-2) 180

360 = (n-2) 180

+360 = 180 -360 +180

+360 = 180 = (3 triangles with 180)

900/180 = 5 sides.

If we say 5 triangles created with 3 given lengths

then same rule applies n-2 (180)

=7 sides

= if regular shape largest line 22 x 7 = 154 ft sq = Area.

Answer:

374

Step-by-step explanation:

First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374
