Change the fraction 3/4 to a percent.
Levart [38]
There is 100% in 1 since this is three parts of 1 we will have to divide 100 by 4 then multiply it by 3.

You can convert this to a percent by just removing the point and the zero and adding a percent at the end.

Maya obtains a $423,000 30/10 balloon mortgage with a rate of 5.65%. What will her monthly payments be? (2 points)
lapo4ka [179]

Answer:

Her monthly payment is approximately $4,611.65

Step-by-step explanation:

The monthly payment on the loan is given by the following formula;

A = P \cdot \dfrac{r\cdot (1 + r)^n}{(1 + r)^n - 1}

A = The monthly payment

P = The principal amount = $423,000

r = 5.65%

The number of years = 10 years

A = 423,000 \cdot \dfrac{\dfrac{0.0565}{12} \cdot \left (1 + \dfrac{0.0565}{12} \right )^{180}}{\left (1 + \dfrac{0.0565}{12} \right )^{180} - 1} \approx 4611.65

Her monthly payment, A ≈ $4,611.65

Help i forgot how to do this
skad [1K]

Answer:

x = 8

Step-by-step explanation:

The diagram shows two similar triangles.  Similar triangles have all the same angles and the sides are proportional to one another.  So, by setting up a proportion of the sides, you can solve for the missing variable:

\frac{bigger}{smaller}=\frac{156}{72}=\frac{(14x+5)}{54}

Cross-multiply:  72(14x + 5) = 156(54)

Distribute:  1008x + 360 = 8424

Subtract 360 from both sides: 1008x + 360 - 360 = 8424 - 360

Divide: 1008x/1008 = 8064/1008

Solve for x: x = 8

A company uses a variable percentage markup of 35% .if the total cost of a product is $15,what is its selling price
monitta

The percentage mark up refers to the amount of money added to the cost price of goods to cover for the overheads and profit. In this case, the mark up price is 35% of the cost price, therefore: (35%=0.35)

Mark up = 0.35 * $15

Mark up = $5.25

However this is not yet the selling price. The selling price is the mark up value plus the original cost price, therefore:

Selling price = $5.25 + $15

Selling price = $20.25

Therefore the product is sold at $20.25.

 

<em>Alternate: </em>Another way to solve this is to directly multiply the cost price by 135%, that is: (135% = 1.35)

Selling price = 1.35 ($15)

<span>Selling price = $20.25</span>
