It would take 6 weeks for Cole to make 750$ and the 65$ he had received from the open mic would make it 815$
Answer:
3.6cm
Step-by-step explanation:
Given data
We are given that the dimension of the photo is
Height= 15cm
Width= 9cm
That is
15cm height will make 9cm width
hence 6cm height will make x widht
cross multiply
9*6= 15*x
54= 15x
x= 54/15
x= 3.6cm
Hence the width will be 3.6cm
Answer:
i think its 1.5
Step-by-step explanation:
sorry if im wrong
<span>A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:
</span><span>2x +6y = 0
y = -x/3
Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.</span>
Answer:
Step-by-step explanation:
Let Carl do the job in c days, Anne- in a, and Bob in b days
Then the portion of job they can do is 1/c, 1/a and 1/b
<u>As per given we have below equations:</u>
- 1/c + 1/b= 1/6
- 1/a + 1/b = 1/3
- 1/a + 1/c = 1/5
<u>Sum of all 3 equations gives us:</u>
- 2(1/a + 1/b + 1/c) = 1/6 + 1/3 + 1/5
- 2(1/a + 1/b + 1/c) = 5/30 + 10/30 + 6/30
- 2(1/a + 1/b + 1/c) = 21/30
- 2(1/a + 1/b + 1/c) = 7/10
- 1/a + 1/b + 1/c = 7/20
It means all three together can complete 7/20 of the job in one day
<u>The rest of the job is done by Anne and Bob:</u>
<u>As Anne and Bob can do 1/3 of the job in one day, they need time to complete the rest:</u>
<u>Add 1 day to this to find overall time:</u>
- 1 + 39 /20 = 59/20 days or 2.95 days
