Bob and mark talk about their families. Bob says he has 3 kids, the product of their age is 72. He gives another clue: the sum o

Bingel [31]

Possible Ages Sum of The Ages 1 2 36 391 4 18 231 8 9 181 3 24 282 3 12 172 4 9 152 6 6 142 2 18 223 3 8 143 4 6 13

The sum has to be 14. So it can be 2, 6, and 6 or 3, 3, and 8.
But it cannot be 3, 3, and 8 because the youngest cannot be a twin.

So it is 2, 6, and 6.

Hope this helps :)

After being dropped a certain ball always bounces back to 2/5 of the height of its previous bounceAfter the first bounce it reac

kap26 [50]

Answer:

8 inches.

Step-by-step explanation:

In the first bounce, the height that the ball reaches was 125 inches.

If the ball always bounces back to $\frac{2}{5}$ of the height, then after 2nd bounce it will reach $(125 \times \frac{2}{5}) = 50$ inches height.

Again, after 3rd bounce, it will reach $(50 \times \frac{2}{5}) = 20$ inches height.

And, after 4th bounce, it will reach $(20 \times \frac{2}{5}) = 8$ inches height. (Answer)

The pressure applied to a leverage bar varies inversely as the distance from the object. If 150 pounds is required for a distanc

AlexFokin [52]

Answer:

500 pounds

Step-by-step explanation:

Let the pressure applied to the leverage bar be represented by p

Let the distance from the object be represented by d.

The pressure applied to a leverage bar varies inversely as the distance from the object.

Written mathematically, we have:

$p \propto \dfrac{1}{d}$

Introducing the constant of proportionality

$p = \dfrac{k}{d}$

If 150 pounds is required for a distance of 10 inches from the object

p=150 pounds
d=10 inches

$150 = \dfrac{k}{10}\\\\k=1500$

Therefore, the relationship between p and d is:

$p = \dfrac{1500}{d}$

When d=3 Inches

$p = \dfrac{1500}{3}\\\implies p=500$ pounds$

The pressure applied when the distance is 3 inches is 500 pounds.
