Answer:
Jake does have enough to buy a dog bone that cost $1.49
Step-by-step explanation:
6 quarters = $1.50
2 dimes = $0.20
1 nickel = $0.05
So add it all together: $1.50 + $0.20 + $0.05 = $1.75
The volume of ball is 113.04 cubic centimeter
<em><u>Solution:</u></em>
Given that we have to find the volume of tennis ball
Since the ball is of sphere shape, we can use the sphere formula
<em><u>The volume of sphere is given by formula:</u></em>
Where, "V" is the volume and "r" is the radius
Given that,
Diameter = 6 cm
Therefore,
<em><u>Substituting in formula, we get</u></em>
Thus volume of ball is 113.04 cubic centimeter
Answer:
3 years
Step-by-step explanation:
As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.
That means Tim is now 4+2 = 6, so will be 9 in 3 years.

<em>Additional comment</em>
If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...
x = Tim's current age; y = Tom's current age.
The sum of their ages 2 years ago was ...
(x -2) +(y -2) = 15
Tom's current age is 13, so we have y=13. Using that in the equation gives ...
x -2 +13 -2 = 15
x = 6 . . . . . . . . . . subtract 9, collect terms
That's Tim's current age, so Tim will be 9 years old in 3 years.
