I’m confused can someone explain?
Novay_Z [31]

Answer:

It is 150 percent

Step-by-step explanation:

You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:

1 1/2 in percent = (1 + 1/2) × 100% =

(1 + 0.5) × 100% = 1.5 × 100% = 150%

Hope this helps! Sorry if I'm wrong.

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?
Anestetic [448]

Answer:

Rudy is 13 years old. Her father is 45 years old.

Step-by-step explanation:

It's very simple actually!

<u>All you need to do is subtract 32:</u>

58 - 32 = 26

<u>Then divide:</u>

<u />

26 ÷ 2 = 13

13 is Rudy's age. Let's find her father's age!

<u>We then add 32 back to 13:</u>

32 + 13 = 45

And there you have it!

Hope this helped!  :)

Graph the function.<br><br> y = 1/5 (3)^x<br><br> Graph A. B. C. or D?
patriot [66]

The function y=3^x is incresing and have positive values for all x. Then the function y=\dfrac{1}{5}\cdot 3^x is also increasing and have positive values for all x. This means that options B (values are negative) and D (function is decreasing) are incorrect.

At x=0, y=\dfrac{1}{5} \cdot 3^x=\dfrac{1}{5} \cdot 3^0=\dfrac{1}{5} \cdot 1=\dfrac{1}{5}.

In option A graph of the function passes through point (0,y), where y is near 3. In option C graph of the function passes through point (0,y), where y is near 1/5. So, you can conclude that the option C is correct.
