Given is :

The radius of the spherical container = 13 units

A square plate rests horizontally in a spherical container and is 1 unit above the bottom point of the container. So, the distance from the center of the sphere to the center of the plate = 12 units. And the distance from the center of the sphere to the corner of the plate is 13 units.

Lets assume the side is 'x' units

Now using Pythagoras theorem, we will find the distance from the center of the plate to the corner :

12^{2} +x^{2} =13^{2}

144+x^{2} =169

x^{2} =25

x=5 units

So, the length of the diagonal becomes 10 units.

Now, we get an isosceles triangle with sides x,x and 10 units.

x^{2} +x^{2} =10^{2}

2x^{2} =100

x^{2} =50

x=\sqrt{50}

Hence, the length of a side of this plate is \sqrt{50} units.

Wilton collected $8.50 in dimes and quarters while cleaning his father's truck. If the number of quarters is 3 times the number
dusya [7]

Answer:

Wilton found 10 dimes while cleaning his father's truck.

Step-by-step explanation:

Given that:

Total amount collected = $8.50 = 8.50*100 = 850 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement,

10x+25y=850     Eqn 1

y = 3x     Eqn 2

Putting y=3x in Eqn 1

10x+25(3x)=850\\10x+75x=850\\85x=850

Dividing both sides by 85

\frac{85x}{85}=\frac{850}{85}\\x=10

As x represents dimes, therefore, number of dimes is 10.

Hence,

Wilton found 10 dimes while cleaning his father's truck.
