L = 20 W = 1
L = 10 W = 2
L = 5 W = 4
Study this carefully. It's a good problem to know how to do. The ancients solved problems by using this method. They started with biggest number they could on the left and multiply each number on the right as they went down (in this case by 2).
Answer:
Option B
Step-by-step explanation:
The circumference of a circle changes from (pre-image)20 to 4(image) after a dilation.
0.3x ≥ 0.6
Divide both sides by 0.3,
0.3x / 0.3 ≥ 0.6/0.3
x ≥ 2
So, your final answer is x ≥ 2
Hope this helps!
Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
Step-by-step explanation:
Diameter (d) = 22 inch
Radius (r) = d/2= 22/2 = 11 inch
π = 3.14
Now
Circumference = 2πr
= 2* 3.14 * 11
=69.08 ich
And now
Area = πr²
= 3.14 * 11²
= 379.94 inch²
