Answer:
9 ft
Step-by-step explanation:
Let's begin with the formula for the volume of a square pyramid. If s is the base length, then the area of the base is s^2. The volume of the pyramid is then V = (1/3)(base area)(height). We know the volume and the base length (s), and want to find the height. Solving V = (1/3)(base area)(height)
for height, we get:
3V = (base area)(height), or
3V
---------------- = height
base area
Substituting 75 ft^3 for V and (5 ft)^2 for base area, we get:
3(75 ft^3) 9 ft
height = ------------------ = ----------------- = 9 ft
25 ft^2 1
Answer:
36girls
Step-by-step explanation:
3/1*12=36. To check 36/12=3/1=3:1
We have been given that the inverse variation 
shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency 
.
To find the required wavelength, we substitute 
in our given equation and solve for x as:
We can see that both numerator and denominator has 3, so we can cancel it out.
Using quotient rule of exponents 
, we will get:
Therefore, the wavelength for radio waves would be 
meters and option B is the correct choice.
Answer:
9/2 or 4 1/2
Step-by-step explanation:
- 3/4 ÷ 1/6 = 3/4 × 6
- 3/4 × 6 = 18/4
- 18/4 = 9/2
- 9/2 = 4 1/2
Therefore, the answer is 9/2 or 4 1/2.
Reflecting the x axis, we multiply the y value by -1, getting (7, -3)
Reflecting the y axis, we multiply the x value by -1, getting (-7, 3)
