Jane has 34 candles leftover from the last craft show and Brianna

katrin [286]

Answer:

4 hours

Step-by-step explanation:

Given that the number of leftover candles for Jane = 34

and the number of leftover candles for Brianna = 2

Rate of candle making for Jane = 24 candles/ hour

Rate of candle making for Jane = 32 candles/ hour

As they work for h hours to make candles.

So, in h hours, the number of new candles made by Jane = 24h candles

For Jane, the total number of candles after h houres, including the leftover candles $= 24h+34 \cdots(i)$

Similarly, in h hours, the number of new candles made by Brianna = 32h candles

For Brianna, the total number of candles after h houres, including the leftover candles $= 32h+2 \cdots(ii).$

As they want to have the same number of candles at their stalls, so equating the numbers of candles from equations (i) and (ii), we have

$24h+34=32h+2 \\\\\Rightarrow 32h-24h=34-2 \\\\\Rightarrow 8h=32\\\\$

$\Rightarrow h=32/8=4$ hours.

Hence, both need to work for 4 hours to have the same number of candles.

Which of the following graphs represent a function? 4072-01-02-01- a. Graph A and Graph C b. Graph A c. Graph D d. Graph B and G

OleMash [197]

<h2>Answer:</h2>

The graph which represent a graph of a function is:

Graph A and Graph C

<h2>Step-by-step explanation:</h2>

We know that a graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to y-axis should intersect the curve exactly once i.e. corresponding to each x-value there is exactly one y-value.

Hence, from the figure attached to the answer we see that the Graph which is a function is:

Graph A and Graph C

If each acute angle of a parallelogram measures 59 degrees, then what is the masure of each obtuse angle?

xenn [34]

A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 = 242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps
