Selmas class making a care package to give to victims of a natural disaster.Selma packs one box in 5 minutes and has already pac
bixtya [17]

Each of them need to work 105 minutes more in order to have packed the same number of boxes.

<u><em>Explanation</em></u>

Suppose, they need to work for x minutes more in order to have packed the same number of boxes.

Selma packs one box in 5 minutes and Trudy packs one box in 7 minutes.

So, the number of boxes packed by Selma in that x minutes =\frac{x}{5} and the number of boxes packed by Trudy in x minutes =\frac{x}{7}

Given that, Selma and Trudy have already packed 12 and 18 boxes.

Now if <u>each of them packed the same number of boxes</u>, then the equation will be......

12+\frac{x}{5}=18+\frac{x}{7}\\ \\ \frac{x}{5}-\frac{x}{7}= 18-12\\ \\ \frac{7x-5x}{35}=6\\ \\ \frac{2x}{35}=6\\ \\ 2x= 210\\ \\ x= \frac{210}{2}=105

So, each of them need to work 105 minutes more in order to have packed the same number of boxes.

1) A scuba diver dives beneath the surface of the water 34 feet. He swims up 13 feet closer to the surface, then swims back down
Nataliya [291]
1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface

2. y = 15x + 50
    220 = 15x + 50
    220 - 50 = 15x
    170 = 15x
    170/15 = x
    11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs

Sholpan [36]

Answer:

z=\sqrt{80}

By geometric mean property:

y= \sqrt {16\times 4}

y= \sqrt {64}

y= 8

By Pythagoras Theorem:

z=\sqrt{4^2 +8^2}

z=\sqrt{16 + 64}

Part A
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

There are several possible outcomes.  If your cross section is created by intersecting the cone with a plane parallel to the base of the cone, the cross section is a circle.  If the plane is held vertical, the cross section could be a hyperbola.  If the intersecting plane is neither vertical nor horizontal, the cross section could be an ellipse.
