the selling price for a refrigerator is 584 if the mark up is 25% of the dealers cost, what is the dealers cost of the refrigerator?
To calculate the dealer's cost of a refrigerator, you can use the selling price and the mark-up percentage by following a step-by-step process.
Mark Up Calculation:
Let the dealer's cost be x.Mark up = 0.25x.Selling price = Dealer's cost + Mark up = x + 0.25x = 1.25x = $584.Solve for x: 1.25x = 584, x = $467.20.Therefore, the dealer's cost of the refrigerator is $467.20.

The measure of an exterior angle of a regular polygon is 15°. What is the sum of the measures of the interior angles of the polygon?
The sum of the measures of the interior angles of a regular polygon, where the measure of an exterior angle is 15°, is 3960°.
Explanation:To answer your question about the sum of the measures of the interior angles of the regular polygon, we can use the formula for computing the sum of the measures of the interior angles of a regular polygon, which is (n-2) * 180 degrees, where 'n' is the number of sides in the polygon.
In a regular polygon, the measure of each exterior angle is equal to the total of 360° divided by the number of sides. Given that the measure of the exterior angle is 15°, we can find 'n' using the equation 360°/n = 15°, which gives us n=24.
Substituting n=24 in the formula for computing the sum of the interior angles, we get (24-2)*180 = 22*180 = 3960°. Hence, the sum of the measures of the interior angles of the polygon is 3960°.

Mr. and Mrs. Patton and their daughter Carolyn own three cars. Carolyn drives 10 miles per week farther with her car than her father does with his. Mr. Patton does twice as many miles per week as Mrs. Patton. If their total mileage per week is 160 miles, how many miles per week does each drive?
Answer: They drive 60 miles, 70 miles, 30 miles respectively.
Step-by-step explanation:
Since we have given that
Total mileage per week = 160 miles
Let the number of miles that her father does be x
Let the number of miles that she does be x+10
let the number of miles that her mother does be [tex]\dfrac{x}{2}[/tex]
so, our equation becomes,
[tex]x+x+10+\dfrac{x}{2}=160\\\\2x+\dfrac{x}2}=160-10\\\\\dfrac{4x+x}{2}=150\\\\\dfrac{5x}{2}=150\\\\x=\dfrac{150\times 2}{5}\\\\x=60\ miles[/tex]
So, her father drives 60 miles.
She drives 60 +10 = 70 miles.
Her mother drives [tex]\dfrac{60}{2}=30\ miles[/tex]
Hence, they drive 60 miles, 70 miles, 30 miles respectively.

There is an average of 3.5×10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approximately 9.88×10^18 liters of seawater.
About how many kilograms of dissolved salt are in the South China Sea?
Enter your answer, in scientific notation, in the boxes.
__ x 10^__ kg
Please help and thank you!
Answer:
3.458 × 10¹⁷
Explanation:
We multiply the amount of salt per liter, 3.5×10⁻², by the amount of sea water in the South China Sea, 9.88×10¹⁸:
(3.5×10⁻²)(9.88×10¹⁸)
Multiplication is commutative; this means we can switch around the numbers we are multiplying:
(3.5×9.88)(10⁻²×10¹⁸)
Multiplying the numbers in the first set of parentheses, we have 34.58.
To multiply the powers of 10, we use the product property; it states that if we multiply powers that have the same base, we add their exponents:
10⁻²×10¹⁸ = 10⁻²⁺¹⁸ = 10¹⁶
This gives us 34.58 × 10¹⁶. In scientific notation, the decimal must be behind the first non-zero digit; this gives us 3.458. When we move the decimal again, we add 1 to the exponent; this gives us 3.458 × 10¹⁷
The kilograms of salt in the South China Sea is required.
The amount of salt in the South China Sea is [tex]3.458\times 10^{17}\ \text{kg}[/tex]
The amount of salt in 1 liter of seawater is [tex]3.5\times 10^{-2}\ \text{kg}[/tex]

when jackson works more than 40 hours in a week , he earns 1.5 times his normal hourly rate for each of the extra hours. jackson worked 43 hours one week. what was his total pay before deductions? justify your answer.
Final answer:
To determine Jackson's total pay before deductions, we calculate his regular pay for 40 hours and his pay for the extra hours he worked.
Explanation:
To calculate Jackson's total pay before deductions, we need to determine his regular hourly rate and the number of extra hours he worked.
First, we need to calculate Jackson's regular pay for 40 hours. Let's say his regular hourly rate is $10. So, his regular pay for 40 hours would be $10 x 40 = $400.
Next, we need to calculate his pay for the extra 3 hours he worked. Since he earns 1.5 times his normal hourly rate for each extra hour, his pay for 3 extra hours would be 3 x ($10 x 1.5) = $45.
Therefore, Jackson's total pay before deductions for the week would be $400 (regular pay for 40 hours) + $45 (extra pay for 3 hours) = $445.
