You have to divide 3 by 1/3 and you get 9. So he has 9 balls.

I hope this helps

He has 3 balls of dough.
You get this answer because if he has 3 pounds and cuts it into 3 pieces than he has 3 balls of 1 pound each.

A 10-foot ladder leans against a wall so that it is 6 feet high at the top. The ladder is moved so that the base of the ladder t

konstantin123 [22]

Answer:

The top of the ladder is now at 10 ft.

Step-by-step explanation:

At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

$B^2=L^2-H^2=10^2-6^2=100-36=64\\\\B=\sqrt{64}=8$

The base is moved twice the distance the height moves up.

We called this distance x, so we have:

$L^2=(H+x)^2+(B-2x)^2=H^2+2Hx+x^2+B^2-4Bx+4x^2\\\\L^2=(H^2+B^2)+5x^2+(2H-4B)x\\\\L^2=L^2+5x^2+(2H-4B)x\\\\0=5x^2+(2H-4B)x\\\\5x+(2H-4B)=0\\\\x=\dfrac{4B-2H}{5}=\dfrac{4*8-2*6}{5}=\dfrac{32-12}{5}=\dfrac{20}{5}=4$

The new height (H+x) is

$H'=H+x=6+4=10$

The base travels 2x=8, so the new base B' is 0.

This means that the ladder is all against the wall (L=H').

I am thinking of a number. If you multiply my number by four, add -4 to the product, and then take 1/3 of the sum, the result is

bogdanovich [222]

Answer:

$x = - \frac{7}{2}$

Step-by-step explanation:

x=unknown number

$\frac{4x + ( - 4)}{3} = - 6$

$4x - 4 = - 18$

$4x = - 14$

$x = \frac{ - 14}{4}$

simplify the fraction so... -7/2
