Answer:

4.32 hours

Step-by-step explanation:

Remember that

1\ day=24\ hours

Looking at the graph

Allen spend attending school 30%

Convert to hours

Multiply the percentage in decimal form by the number of hours in a day

0.30(24)=7.2\ h

Allen spend listening to music 12%

Convert to hours

Multiply the percentage in decimal form by the number of hours in a day

0.12(24)=2.88\ h

Find the difference

7.2-2.88=4.32\ h

By selling a watch in Rs 150 and Rs 200 loss and profit are happened
Travka [436]

Answer:

Rs 175

Step-by-step explanation:

Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).

At Rs200, the profit is 200-x.

So we have an equation: minus 150 minus x is equal to 200 minus x.

To solve the equation, the cost price X is Rs175.

Make a conjecture about the sum of the first 15 positive even number
erica [24]
I conclude that the sum will be even because any even number can be represented by 2n where n is a whole number
and even numbers are 2 apart, so
the sum of the first 15 are
2n+2(n+1)+2(n+2) etc until we get to 2(n+14)
we can undistribute the 2 from all of them and get
2(n+n+1+n+2...n+14)
and we are sure that whatever is in the parenthasees is a whole number because whole+whole=whole
therefor, the sum is even

if you did want to find the sum then
an=2n
the 15th even number is 30
the first is 2
S15=15(2+30)/2=15(32)/2=15(16)=240
which is even

B/5&gt;-1<br> Solve the inequality. Graph and check the solution.
Usimov [2.4K]

Answer:

b>-5

Step-by-step explanation:

\frac{b}{5}   >  - 1

Multiply by 5 to isolate b.

b  >  - 5

If you graph this on a line, it would be a hollow point facing the right, since it's any number greater than five, not including 5.

If you put any number greater than -5, you'll output greater than - 1.
