The bike Razi wants to buy costs
$250. He babysat 4 times for a total of 15
hours. He has also mowed the lawn 5 times.
Has he earned enough money to buy the
bike?

Answers

Answer:

Not enough information

Step-by-step explanation:

So, we first know that the bike costs 250 dollars. We also know that he babysat for 15 hours, and mowed the lawn 5 times. However, we do not know how much money he has, or how much he made. Sure, doing extra chores could of made him money, but in this question it doesn't say how much money he made. Therefore, we cannot answer this question because, although we have the value of the bike's cost, we do not know how much Razi has. Hope this helps you!

What is the difference between greatest common divisor and greatest common denominator ?

Answers

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators

Step-by-step explanation:

In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.

A company's flexible budget for 12,500 units of production showed sales, $50,000; variable costs, $20,000; and fixed costs, $15,000. The operating income expected if the company produces and sells 15,000 units is:

Answers

Answer: $21000

Step-by-step explanation:

First, we calculate the contribution margin which will be:

=Sales - Variable cost

= $50,000 - $20,000

= $30,000

Therefore, the contribution margin per unit will then be:

= $30,000 / 12500

= $2.4 per unit

The operating income will be the difference between the total contribution margin and the fixed cost. This will be:

The total Contribution margin will be:

= $2.4 × 15000

= $36000

Fixed costs = $15000

Operating income = $36000 - $15000

= $21,000

Si un capital de 6800 soles se presta a 12% anual, durante a años y 19 días, ¿Qué interés producirá?

Answers

El número de años no se da de forma exhaustiva. Usando un valor hipotético

Respuesta:

Por favor, consulte la explicación.

Explicación paso a paso:

Suponga que el número de años es igual a 1 año 19 días

Convertir en años; 19 días es igual a 19/365 = 0,0520547; por lo tanto, 1 + 0.0520547 = 1.0520547 años

Recuerde la fórmula de interés simple:

Interés = principal * tasa * tiempo

Interés = 6800 * 0,12 * 1,0520547

Intereses = 858,4766352

Por tanto, si el plazo es de 1 año 19 días; interés = 858.4766352

Si el número de años en el período es diferente, simplemente siga el mismo paso para convertir los días y sume al número exacto si los años se dan.

6. Nicole earned $72 in 9 hours At this rate, how
much would she earn in 12 hours?

Answers

Answer:

96

Step-by-step explanation:

Because 72/9 = 8 so every hour she earns 8$

8*12=96

The amount of money in dollars earned by Nicole in 12 hours will be $96.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Nicole earned $72 in 9 hours. Then the amount of money in dollars earned by Nicole each hour is calculated as,

Rate = $72 / 9

Rate = $8 for each hour

At this rate, the amount of money in dollars earned by Nicole in 12 hours will be calculated as,

⇒ $8 x 12

⇒ $96

The cash in dollars acquired by Nicole in 12 hours will be $96.

A suit is on sale for 71% off. The sale price is $278.40.
What is the regular price?

Answers

Answer:

it looks like the answer is $476.06.

Step-by-step explanation:

i got this answer because we already know the sale price. We need to find the regular/ original price of the suit. So in order to do that all you have to do is:

278.40 * 71%= 197.664

now add both together because 197.664 is how much the discount was. So, now add both together. 278.40 + 197.664. Now this gives you, 476.064, round it and you should get $476.06 for the original/regular price.
