How approximate is approximate?
I'll give you an answer to 2 decimal places.
Area = pi * r^2
r = d/2
d = 14
r = 14/2
r = 7
Area = 3.14 * 7^2
Area = 3.14 * 49
Area = 153.86 sq in.
Lots of pizza! Enjoy!
Got a calculator? all you do for #1 and #2 is multiply the two numbers and that is the value for x.
These problems are cross multiplication.
For the next two:
.25x = 6
divide both sides by .25
x = 24
NEXT ONE:
.49x = 12
divide both sides by .49
x = 24.48
Answer:
the 5 seated table with the 2 pizzas got more each.
Step-by-step explanation:
pieces each
pieces each
pieces each
Now change the fractions s that they all have a common denominator.
Thus meaning that the 5 seated table with the 2 pizzas got more each.
Answer:
(-1, -9)
Step-by-step explanation:
Recall that for 2 points (x1, y1) and (x2,y2)
the midpoints are given by
x ordinate = 
y ordinate = 
In our case x1 = 8, y1 = -10, x2 = -10, y2=-8
x ordinate = = [8 + (-10) ] / 2 = -1
y ordinate = = [-10 + (-8) ] / 2 = -9
hence midpoint is (-1, -9)
Answer: y = 64
Step-by-step explanation:
y <> x² ----------------------- 1
y = kx² ----------------------- 2
36 = 3²k
36 = 9k
K = 36/9
= 4.
To find y when x = 4, we substitute for x in equation 2
y = kx²
y = 4²k
y = 16 x 4
y = 64
