Answer: Justin  dirty laundry was  reduced by 74. 18%

Step-by-step explanation:

Step 1

Total amount of clothes = 124 pieces

 Number of clothes reduced to = 32 pieces

To find the amount of the reduction, We will first Subtract the  number reduced to from the initial amount of clothes  giving us

Amount of reduction =  124- 32 =92 pieces of clothes

Step 2---Then we Divide the amount of the reduction of the clothes  by the total amount of clothes  to find the rate of reduction, giving us

Rate of reduction =  92/124 = 0.741

Step 3--- we finally Multiply the rate of reduction of clothes by 100 to find the percentage reduction.

0.741 x  100 = 74. 18%

A series of quarterly payments of P1,300 each at the first payment is due at 4 years, and the last payment at the end of 12 year
gtnhenbr [62]

Answer:

The Value of Payments is  P18,557.15

Step-by-step explanation:

The quarterly payment is an annuity payment.

Use the following formula to calculate the present value of the payments.

PV of Annuity = Annuity Payment x ( 1 - ( 1 + interest rate )^-Numbers of periods ) / Interest rates

Where

Annuity Payment = Quarterly payment = P1,300

Interest rate = 5.12% x 3/12 = 1.375%

Numbers of periods = 4 years x 12/3 = 16 quarters

PV of Annuity = Value of Payments  = ?

Placing values in the formula

Value of Payments = P1,300 x ( 1 - ( 1 + 1.375% )^-16 ) / 1.375%

Value of Payments =  P18,557.15

If all the dimensions of the rectangular pyramid are multiplied by 1/5, what is the effect on the volume
Pachacha [2.7K]

Answer:

If all the dimensions of the rectangular pyramid are multiplied by 1/5, the volume will be 125 times smaller.

Step-by-step explanation:

A rectangular pyramid has the following dimensions:

length(l), height(h) and width(w)

The volume is:

V = \frac{l*h*w}{3}

If all the dimensions of the rectangular pyramid are multiplied by 1/5

Then we have that:

l = \frac{l}{5}, w = \frac{w}{5}, h = \frac{h}{5}

The modified volume will be:

V_{M} = \frac{\frac{l}{5}*\frac{w}{5}*\frac{h}{5}}{3} = \frac{\frac{l*w*h}{125}}{3} = \frac{l*h*w}{125*3} = \frac{1}{125}(\frac{l*h*w}{3}) = \frac{V}{125}

So

If all the dimensions of the rectangular pyramid are multiplied by 1/5, the volume will be 1/125 of the original, that is, 125 times smaller.

MATH HELP!?
Debora [2.8K]
<span><u><em>The correct answers are: </em></u>
 1) C
 2) A
 3) D

<u><em>Explanation</em></u><span><u><em>: </em></u>
1) <u>Voluntary deductions</u> are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.

 2) <u>FICA</u> is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.

 3) <u>A fixed expense</u> would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.</span></span>

If the diagonals of a quadrilateral bisect the angles, is the quadrilateral always a parallelogram? Explain your answer.
Liula [17]
Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.


Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).

Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.
