Tom and Jerry leave from the same place in opposite directions. Tom drives 38mph. Jerry drives 50mph. In how many hours are they

devlian [24]

Answer:

Both Tom and Jerry will apart 176 miles in 2 hours .

Step-by-step explanation:

Given as:

Tom and Jerry moves in opposite direction

The speed of Tom = 38 mph

The speed of Jerry = 50 mph

Let The distance cover by Tom = x mile

The distance cover by Tom = ( 176 - x ) miles

Time taken by both are same = T hour

$\textrm(Time) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, Time taken by Tom

T = $\frac{x}{38}$ ... 1

∴ x = 38 T

And Time taken by Jerry

$\textrm(T) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, T = $\frac{176 - x}{50}$

So , put the value of T from 1

$\frac{x}{38}$ = $\frac{176 - x}{50}$

Or, 50 × x = ( 176 - x ) × 38

So 50 x + 38 x = 6688

Or, 88 x = 6688

∴ x = $\frac{6688}{88}$ = 76 mile

So, From, eq 1

T = $\frac{x}{38}$

or, T = $\frac{76}{38}$ = 2 hours

Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer

You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay you

Mazyrski [523]

Answer:

6 times

Step-by-step explanation:

1. There was no cents left

2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)

3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)

4. It equals 6 and 6 is a even number

5. Sorry this was too confusing

Jill has a poster hanging in her room whose width is 212 in. shorter than its length. The perimeter of the poster is 103 in. How

zhuklara [117]

The poster is a rectangle.
P = 2 L + 2 W
where L is the length and W is the width of a rectangle.
L = W + 2 1/2 = W + 2.5
103 = 2 ( W + 2.5 ) + 2 W
103 = 2 W + 5 + 2 W
103 = 4 W + 5
4 W = 103 - 5
4 W = 98
W = 98 : 4
W = 24.5 in
L = 24.5 + 2.5
L = 27 in
Answer:
The poster is 27 inches long and 24.5 inches wide.
