Answer:

the answer would be 13.75 feet

Step-by-step explanation:

The computation of the tall is the building as follows:

Given that

Base is 6 foot

And, the hypotheses is 15 feet

Here we use the Pythagoras theorem

= √15^2 - √6^2

= √225 - √36

= √189

= 13.75 feet

Hence the answer would be 13.75 feet

dexar [7]

Answer:

The probability that next selection is yellow marble = 63% .

Step-by-step explanation:

Given the selection of yellow marbles = 41 times.

The selection of white marble = 24  times.

Total number of selections made = 65

Now calculate the probability that the next selection will be the yellow marble. Therefore, the probability of getting yellow marble can be determined by dividing the yellow selection by total number of selections.

\text{P(yellow)} = \frac{ \text{The selection of yellow marbles} }{ \text{ Total number of slections }} \\\text{P(yellow)} = \frac{41}{65} = 0.63 \ or \ 63 \ percent

dangina [55]

Answer:

The answer is $44.73 and what ever the explain part said on the question is not reasonable.

Step-by-step explanation:

I say this because there are 5 friends and each bill for them is $7.75 so $7.75 times 5 equal $38.75 and then the extra money for dessert is 2.99 but two times so when u add those two to $38.75 it equals $44.73.

What is the value of x?<br><br> A. 2 Units<br> B. 3 Units<br> C. 5 Units<br> D. 8 Units
Fudgin [204]

You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be \frac{BD}{AD}=\frac{CD}{BD} where BD is your altitude. The formula then, filled in accordingly, would be \frac{10}{x}=\frac{4x}{10}. We cross multiply to get that 4x^2=100. Divide both sides by 4 to get x^2=25, so x = 5. Choice C is the one you want.
