Notice that both sides of the equation have a similar form. If we ignore angle functions we end up with,

$A+A\cdot B=B+B\cdot A$

That is true if condition $A=B$ is met.

Otherwise it is false.

Hope this helps.

Chang made $156 for 13 hours of work at the same rate, how many hours would he have to work to make $108?

sdas [7]

Answer:

9 hours

Step-by-step explanation:

"At the same rate" means time and wages are proportional.

time/wages = t/$108 = (13 h)/$156

t = 108(13 h)/156 . . . . . . . . . . . . . . . units of dollars cancel

t = 9 h

Chang would have to work 9 hours to make $108.

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to

san4es73 [151]

Answer:

28 different ways

Step-by-step explanation:

This is a combination question. Combination has to do with selection.

Total number of element in the set = 8

Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}

Total number divisible by 6 or 8 is 6

The number of ways we can choose 6 items from 8 is expressed as;

8C6 = 8!/(8-6)!6!

8C6 = 8!/(2)!6!

8C6 = 8*7*6!/2!6!

8C6 = 8*7/2

8C6 = 56/2

8C6 = 28 ways

Hence there are 28 different ways

Martina chose a random sample of 10 bags of candy from two different Brands, A and B. All bags in the sample are the same size.

Alborosie

I found the dot plots that accompanies this problem.

Based on the plots, the <span>statement that gives is a valid comparison of the number of candies in the bags of the two Brands is:

</span><span>B. The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A.

Dots in Brand B are scattered and whereas dots in Brand A are not and they are more concentrated between 52 to 55 range. </span>
