Answer:
84
Step-by-step explanation:
Total students he surveyed: 27
Amount that found it something OTHER than easy: 14 (11 moderate + 3 difficult)
This means that 
found it something other than easy
Multiply that by 162 to find the proportion for the larger population:
162 * (14/27), and we get 84.
1950000 we know that 1 hg equal to 1000cg so 1000x195= 1950000
Answer:
8.695=area of shaded region
Step-by-step explanation:
pi x 16=50.265
this is the whole circle
the radius is also the side of the hexagon
the picture is formula for area of hexagon
if you replace a by the side which is 4
the answer is 41.57
50.265-41.57=8.695
Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
If the question is actually “danielle ran the first 1/5 of a 6 mile race. how many miles did she run?” then the answer is 1 & 1/2 miles.
