Answer:
8.52
Step-by-step explanation:
127.81/15=
Answer:
50.24
Step-by-step explanation:
You will do
(area of a circle) x (hight)
Area of a circle = A
lets say 3.14 is pi
A = 3.14 x 2^2
A = 3.14 x 4
A = 12.56
Now
V = 12.56 x 4
V = 50.24
Answer:
1) x ≤ 2 or x ≥ 5
2) -6 < x < 2
Step-by-step explanation:
1) We have x^2 - 7x + 10, so let's factor this as if this were a regular equation:
x^2 - 7x + 10 = (x - 2)(x - 5)
So, we now have (x - 2)(x - 5) ≥ 0
Let's imagine this as a graph (see attachment). Notice that the only place that is above the number line is considered greater than 0, and that's when x ≤ 2 or x ≥ 5 (the shaded region).
2) Again, we have x^2 + 4x - 12, so factor this as if this were a regular equation:
x^2 + 4x - 12 = (x + 6)(x - 2)
So now we have (x + 6)(x - 2) < 0
Now imagine this as a graph again (see second attachment). Notice that the only place that is below 0 (< 0) is when -6 < x < 2 (the shaded region).
Hope this helps!
Answer:
C. side a is 3.5 inches and side b is 3 inches
Step-by-step explanation:
The scale factor 6:1 means that the sides of bigger rectangle are six times bigger than the smaller rectangle.
To find the sides of the smaller rectangle, divide each side of the bigger rectangle by 6.
Solve side a:
21/6 = 3.5
Solve side b:
18/6 = 3
