Answer:
22 times 4 1/2 divided by 2
Answer:
(-22, -18)
Step-by-step explanation:
Midpoint=(
you already know the midpoint, so you're kind of working backward.
Midpoint (-2, 4)
you'll need to work each part of the equation separately to find x and y
x first
-2=
solve for x
multiply both sides by 2
-4 = x+18
subtract (18) from both sides
-22 = x
now y
4=
solve for y
multiply both sides by 2
8 = y+26
subtract 26
y = -18
second endpoint (-22, -18)
Answer:
Step-by-step explanation:
Recall that the volume of a whole sphere is given by the formula:
then, the volume of a semi-sphere would be half of the formula above:
Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.
which makes our calculation:
Answer:
C!
Step-by-step explanation:
To find the the mean add all the numbers and divde by the number of numbers. The sum of all the numbers is 56. There are 7 numbers.
56/7 is 8.
Go on way math to find it.
