The answer is D. The result from the first cube can't affect what you get. In fact, if you had 1 cube and you threw it twice, the second result would still be independent from the first result.

a city stores fresh water in a spherical tank. The tank has a radius of 32 feet. One cubic foot is approximately 7.5 gallons. If

Serjik [45]

Answer: There will be about 888,915 gallons of water left in the spherical tank.

First, we need to determine the volume of the tank. The volume formula for a sphere is (4/3)pi(r^3). All we have to do is input the 32 for pi and evaluate. You will have a volume of 137,189 cubic feet.

Now, multiply that by 7.5 and you will have 1,028,915 gallons of water in the tank.

Finally, just subtract the 140,000 gallons and we are at our answer.

HELP ME PLZ!!!!!!!! Find the solution of this system of equations.

Strike441 [17]

Set equal to each other since both equal 90

5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0

5(0)-6y=-90
-6y=90
divide by -6
y=-15

(x,y)
(0,-15)

Answer:

Step-by-step explanation:

Two triangles are congruent if they have the same three sides in proportion and they have exactly the same angles.

If the angles are different, the triangles are not similar.

Help with the following problem please

Effectus [21]

Given:
The largest circle has a radius of R=7 units.
Let x be the radius of the large shaded circle.
The small shaded circles have a radius of 1/5 of the large shaded circle.
=> the small shaded circles have a radius of r=x/5

By adding up radii, we have the equation
2(r+x+r)=2(x/5+x+x/5)=2R=2*7=14
Simplify:
7x/5=14/2
x=5
=> r=1

Area of outer circle = $\pi R^2=\pi7^2=49\pi$
Area of large shaded circle = $\pi x^2=\pi5^2=25\pi$
Area of 4 small shaded circles = $4\pi r^2=4\pi1^2=4\pi$
Total area of shaded circles = $25\pi+4\pi=29\pi$

Shaded area as a fraction of that of the outer circle
$=\frac{29\pi}{49\pi}=29/49$
