Danny is measuring two pyramids whose bases are squares. Given the height hhh and volume VVV of the first pyramid, Danny uses th

e formula a=\sqrt{\dfrac{3V}{h}}a= h 3V ​ ​ a, equals, square root of, start fraction, 3, V, divided by, h, end fraction, end square root to compute its base's side length aaa to be 555 meters. The second pyramid has the same volume, but has 444 times the height. What is the side length of its base?

Answer: THE ONE ABOVE IS WRONG

A= 3V/h

​

Step-by-step explanation:

Formulas may contain multiple variables, along with known numbers and letters that stand for known constants like \piπpi.

We can highlight a certain variable in the formula by treating the formula as an equation where we want to solve for that variable.

In this case, we need to solve the equation V =\dfrac{1}{3}AhV=

3

1

​

AhV, equals, start fraction, 1, divided by, 3, end fraction, A, h for AAA.

Hint #22 / 3

\begin{aligned} V&=\dfrac{1}{3}Ah \\\\ \dfrac{3V}{h}&=A \end{aligned}

V

h

3V

​

​

 

=

3

1

​

Ah

=A

​

Hint #33 / 3

This is the result of rearranging the formula to highlight the base area:

A=\dfrac{3V}{h}A=

h

3V

In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie
son4ous [18]

Answer:

Step-by-step explanation:

1) find the total candies

7 + 8 + 5 + 9 = 29

2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find

- red = 7/29

- blue = 8/29

- yellow = 5/29

- green = 9/29

3) compound probability

(red + blue)/29 = 15/29

(yellow + green)/29 = 14/29

(blue + yellow + green)/29 = 22/29
