Joan gets $1,000 paycheck each month. She saves $50 from each paycheck. What percent of her paycheck does Joan save?

kirill [66]

Answer:

The percentage of paycheck Joan saves is 5% .

Step-by-step explanation:

Given as :

The paycheck that Joan gets each months = x = $1,000

The money that Joan saves from each paycheck = y = $50

Let The percentage of paycheck Joan saves = z%

<u />

<u>Now, According to question</u>

The percentage of paycheck Joan saves = $\dfrac{\textrm money that Joan saves from each paycheck}{\textrm total paycheck money}$ × 100

Or, z = $\dfrac{y}{x}$ × 100

Or, z = $\dfrac{50}{1000}$ × 100

Or, z = 5%

So, The percentage of paycheck Joan saves = z = 5%

Hence,The percentage of paycheck Joan saves is 5% . Answer

Answer:

$\int^{\pi}_{0}sin(x)dx = 2$

Step-by-step explanation:

To solve for the value of $\int^{\pi}_{0}sin(x)dx$ , we need to first find the antiderivative of $sin(x)$ .

Since the derivative of $cos(x)$ is $-sin(x)$ , therefore the derivative of $-cos(x)$ is $sin(x)$ . With this:

$\int^{\pi}_{0}sin(x)dx = -cos(\pi)-(-cos(0))$

$=-cos(\pi)+cos(0)$

$=-(-1)+1$

$=2$

∴ $\int^{\pi}_{0}sin(x)dx = 2$

Hope this helps :)

Maya designed two intersecting roads. She drew the roads so that one of the angles at the intersection was 45 degrees. What are

Citrus2011 [14]

The sum of opposite angles are equal, so two of the angles are 45°. The sum of all angles about the intersection of two lines is 360°. So the remaining two angles are found by:

α=(360-2*45)/2

α=135° thus all four angles are:

45°,135°,45°,135°
