Answer:

100 Candy Bars

Step-by-step explanation:

Hey!

==================================================================

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

--------------------------------------------------------------------------------------------------------------

We can create an algebraic Equation to solve this.

- We know that Each Candy Bar costs $1.50.

-We multiply the Amount of Candy Bars with the price.

-We know the profit should be $150

⇒ 1.50x = 150

-Divide by 1.50 on both sides

⇒ 1.50x/1.50 = 150/1.50

-Simplify

⇒ x = 100

==================================================================

Hope I Helped, Feel free to ask any questions to clarify :)

Have a great day!

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

Dmitrij [34]

The relationship between wavelength and frequency is expressed by the equation λν=c where λ is the wavelength, v is the frequency and c is the speed of light which has a value of 3x10^8 m/s.

λν=c
λ(3 × 10^9)= 3x10^8
λ = 0.1 m

Hope this answers the question.

Martin burns 360 calories running for 30 minutes. Paul burns 165 calories for every 15 minute he runs. If Kara runs for 20 minut

Yanka [14]

Answer: She would have to burn between 220 and 240 calories per minute to have a calorie burn rate between those of Martin and Paul.

Step-by-step explanation:

Martin:

360 calories / 30 min = 12 calories/min

Paul:

165 calories / 15 min = 11 calories/min

Kara:

Needs to burn between 11 and 12 calories/min, so we'll calculate the range:

11 calories/min x 20 min = 220 calories (minimum # calories she can burn)

12 calories/min x 20 min = 240 calories (maximum # calories she can burn)
