Let's thing

949 ----- 100% of the price

499 ------ x% of the price

Multiply in cross

949.x = 100.499

949x = 49900

x = 49900/949

x = 52,58%

So, rounding it 52,58% ≈ 53%

Answer:

the period of this graph is 2 $\pi$

Step-by-step explanation:

The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = 2 $\pi$

2 $\pi$ - 0 = 2 $\pi$

Therefore, the period of this graph is 2 $\pi$

What is the percent error of 7cm

antoniya [11.8K]

The answer is 7.14%

Your ruler measuring centimeters has lines for each centimeter. The rule for error is anything between 6.5 and 7.5 is considered 7cm. So the degree of error is plus or minus .5cm.
Your aim is 7cm so you divide your error of .5 by your target measurement. .5/7= 7.14 percent.
