Jonathan's parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games. His friend Lucas's parents told their son that he can play 30 minutes for every hour of homework or reading time he completes. If both boys spend the same amount of time on homework and reading this week, which boy gets more time playing video games? How do you know?

Answers

Jonathan spends more time playing video games because 3/5 of the time he is playing video games, while Lucas is only playing thirty minutes out of sixty, which simplifies into 1/2.Jonathan plays 60% of the time and Lucas plays 50%.(I overdid it a little sorry)

The easiest way to explain this is by using an example. If both boys read and do homework for 10 hours:

Jonathan
5:3 = 10: 6 Jonathan will play video games for 6 hours.

Luca
2:1 = 10:5 Luca will play video games for 5 hours.

If both boys spend the same amount of time on homework and reading this week, Jonathan gets more time playing video games.

Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?

Answers

Answer:

Any equation of the line that is different from y=x is the solution to the problem.

Step-by-step explanation:

step 1

Find the slope of the line that passes through the points (1, 1) and (5, 5)

m=(5-1)/(5-1)=1

step 2

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have m=1

(x1,y1)=(1,1)

substitute

y-1=(1)(x-1)

y=x-1+1

y=x

therefore

Any equation of the line that is different from y=x is the solution to the problem.

A triangle has side lengths measuring 3x cm, 7x cm, and h cm. Which expression describes the possible values of h, in cm? 4x < h < 10x 10x < h < 4x h = 4x h = 10x

Answers

Answer:

4x < h < 10x

Step-by-step explanation:

The triangle inequality theorem tells us that the 3rd side of a triangle will always be between the sum of the lengths of the other two sides and the difference of the lengths of the other two sides.

For example, If the lengths of a triangle are 5 and 10, the 3rd side length would be (let third side be x):

10 - 5 < x < 10 + 5

5 < x < 15

Now, looking at our problem, the third side, h, would be:

7x - 3x < h < 7x + 3x

4x < h < 10x

This is correct.

Answer:

4x < h < 10x

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?

Answers

Shaded circles = 4
Total circles = 12

$(shaded~circles)/(total~circles)$ = $(4)/(12)$

$(4)/(12)$ as a simplified expression = $(2)/(6)$
We can simplify it even more = $(1)/(3)$

Fraction = $(1)/(3)$

Equivalent decimal = 1 ÷ 3 = 0.33
