richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answers
Answer:
His gross pay for the month is $4,509.50
Step-by-step explanation:
The commission Richard Klein earns for oil change = 3.00%
The commission he earns for tune ups = 5.00%
The commission he earns for auto parts sales = 6.25%
The minimum salary he is guaranteed = $2,450.00
The amount he brought in last month includes;
1) $2,500.00 in oil changes
2) $4,500 in tune ups
3) Sold $28,200.00 in parts
The amount he earns last month in commission are;
3/100 × 2,500 = 75 in oil changes
5/100 × 4,500 = 225 in tune ups
6.25/100 × 28,200 = 1762.5 in parts sold
The total commission = 72 + 225 + 1762.5 = 2,059.5
∴ The total commission = $2,059.5
The amount he makes as salary = $2,450.00
Richard Klein's gross pay for the month = His total pay for the month
Therefore;
Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

Which angle is complementary to DFE? Pls answer
Answers
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).

y = 4x-9
y = ax+6
Answers
Answer:
a = 4
Step-by-step explanation:
a = 4
If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.
Answer:
x can not equal zero, as it would cause division by zero.
Step-by-step explanation:
First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:
4x - 9 = ax + 6
If we solve for a, we get:
ax + 6 = 4x - 9
ax = 4x - 15
a = 4 - 15 / x
With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.
find out the total volume of cube _Edge Length =6 inches
Answers
Given:
The edge length of a cube = 6 inches
To find:
The volume of the cube.
Solution:
We know that, the volume of a cube is
[tex]V=a^3[/tex] ...(i)
Where, a is the edge length.
Substituting a=6 in (i), we get
[tex]V=(6)^3[/tex]
[tex]V=216[/tex]
Therefore, the total volume of the cube is 216 cubic inches.
Find the area of the shaded region. Round your answer to the nearest tenth if needed.
Answers
Answer:
140 inches
Step-by-step explanation:
Find the area of the square.
4 + 10 = 14 (Length)
11 + 4 = 15 (Breadth/Width)
Area = 14 x 15 = 210 inches
Find the area of the 2 unshaded squares in the square.
Area of square at the top = 4 x 4 = 16 inches
Area of square at the bottom = 6 x 9 = 54 inches
Add the 2 squares of the area together.
16 + 54 = 70 inches
Now deduct the area of the huge box by the area of the 2 unshaded squares.
210 - 70 = 140 inches

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
