Answer:
n= 26, so the answer would be 'B'.
Step-by-step explanation:
n-8=18
n=18+8
n=26
Answer:
41
Step-by-step explanation:
b^2 -2ac
Let a=4 b=3 c=-4
( 3)^2 -2 (4) (-4)
Exponents first
9 - 2 (4) (-4)
Multiply
9 + 32
41
Answer:
Dividing negative exponents is almost the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.
Step-by-step explanation:
The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.
*<em>look at the image I attached for a better explanation</em>
By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation
Thus the <u>missing side length is 8 cm</u>

Answer:
7068.58 yd³
Step-by-step explanation:
A half sphere would use the normal equation for the volume of a sphere and then divide it by two. The first step would be to find the radius of the sphere, which is half the diameter.
d=30 yd
r=d÷2
r = 30 yd÷2
r = 15 yd
Next, we need to use the volume of a sphere equation to find the volume of the full sphere.
V = 4×π×r³÷3
V = 4×π×15 yd³÷3
V = 4×π×3375 yd³÷ 3
V = 13500π yd³ ÷ 3
V = 4500π yd³
Next, we need to find the volume of the dome by dividing by 2.
V = 4500π yd³ ÷ 2
V = 2250π yd³
V = 7068.58 yd³
The total volume of the dome is 7068.58 yd³
