# The radius of a sphere is 6 inches. Find the length of a chord connecting two perpendicular radii.

6√2.

Step-by-step explanation:

The two radii are equal length and form a right angle, so the resulting triangle is 45-45-90.  Therefore, the length of the chord (the hypotenuse of the triangle) is 6√2.

An Egyptian pyramid has a square base that measures 80 meters on each side. If the height of the pyramid is 30 meters, what is the slant height of the pyramid?

50 meters

The slant height is the height of a triangle making up the base of the pyramid. We can imagine a right triangle with one leg being a vertical line from the peak of the pyramid going down to the center of the base, and the other leg going from the center of the base to the center of one edge of the base. And finally, the hypotenuse will join the ends of those 2 lines together and will also be the slant height of the pyramid. Then we can easily use the Pythagorean theorem to determine the slant height. So
S = sqrt((80/2)^2 + 30^2)
S = sqrt(40^2 + 30^2)
S = sqrt(1600 + 900)
S = sqrt(2500)
S = 50

So the slant height of the specified pyramid is 50 meters.

Determine the amount of money you would have if you invested \$15,000 dollars for 11 years at 3% annual interest compounded continuously. PLEASE INSTEAD OF GIVING THE ANSWER TYPE IN THE FORMULA FOR THE EQUATION

The amount after 3 years of investment is \$20763  .

Step-by-step explanation:

Given as :

The principal invested = p =\$15,000

The rate of interest = r = 3% compounded annually

The time period = t = 11 years

Let The Amount after 3 years = \$ A

From Compounded method

Amount = Principal ×

Or, A = p ×

Or, A = \$15,000 ×

Or, A = \$15,000 ×

Or, A = \$15,000 × 1.3842

Or, A = \$20763

So, Amount = A = \$20763

Hence The amount after 3 years of investment is \$20763  . Answer

Mateo ate 3/8 of a pizza, which was a total of 510 calories of food. Which equation can be used to determine the total number of calories in the entire pizza? 1. 3/8x = 510
2. X/510 = 3/8
3. 3/8 = 510x
4. 3/8(510) = x

The answer is 1. 3/8x = 510

We know this because if we are eating 3/8 of the pizza, and we assume that the total number of calories in the pizza is x, then 3/8 of x will give us the amount of calories that we ate, which is 510. Therefore when we write this equation we get:
3/8x = 510 (3/8 of x is equal to 510)
