Answer:
points on the boundary line: (0, 10), (20, 0)
solution points not on the boundary line: (100, 100)
Step-by-step explanation:
We cannot tell from the posted picture whether the boundary line is solid or dashed, so the answer above is split into two parts. If the boundary line is solid (x+2y≥20), all three listed points are in the solution set. If the boundary line is dashed (x+2y>20), only (100, 100) is in the solution set
Answer:
56
Step-by-step explanation:
There are 7 octagons each side has 8 so you can do 7x8 which gives your 56 or you can draw out 7 octagons which shows that you drew out 56 sides
Answer:
1.4
Step-by-step explanation:
This is because the 4 is in the hundreds place but the 0 is in the hundreds in the second one.
(Decimals are backwards from whole numbers.)
Answer:
$14.50x.20= $2.90
Step-by-step explanation:
This problem can be solved by making use of the Cosine Law. In general form, it is:
b2 = a2 + c2 - 2ac cos B
The given values are:
a = 8.75 cm
c = 4.26 cm
B = 87<span>°
Plugging in the values:
b2 = 8.75^2 + 4.26^2 - 2(8.75)(4.26) cos 87
b = 9.53 cm
So, the answer is:</span>
C. 9.53 centimeters
