Divide both sides by -2
two negatives make a positive and that's true so x = 16/2 so divide it
x = 8 because 2 x 8 = 16 and 2/16 = 8 so true.
Answer: x = 8.
The answer is D because it can only have one symmetrical line straight down the middle.
11 because 275÷25 is 11. 11 calculators would cost 275 in total
The volume of the sphere is 1437.33 ft³
<h3>
</h3><h3>What is volume of sphere?</h3>
A sphere's volume V is four-thirds of pi times the radius cubed. A hemisphere's volume is half of the volume of the associated sphere.
The volume of a spherical.
V= 4/3 πr³
radius= 7ft
So,
V= 4/3*22/7*7*7*7
V= 30184/21
V = 1437.33 ft³

Answer:
C) 4√3
Step-by-step explanation:
The given triangle is an equilateral triangle. BD is angle bisector.
Triangle BCD is a 30-60-90 degree triangle in the ration of 1:√3:2
Here we are given BC, that is highest length of the side.
So 2x = 8
x = 8/2
x = 4.
BD = √3 x
Now plug in x =4, we get
Height (BD) = 4√3
Thank you.
