Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times
Answer:
2.3%
Step-by-step explanation:
The formula to convert x into z distribution is

Where z is the test statistic
x is what we are looking for (in this case 37)
is the mean (in this case, it is 25)
is the standard deviation (we have 6)
<em>Plugging these into the formula, we get:</em>

Thus we can say we want 
<u>Note: </u> 
The table given is for any z where 
Thus, now we have:

0.0228 into percentage is 0.0228 * 100 = 2.28%
Rounded, we get 2.3%
Third answer choice is right.
Answer:
72.5°
Step-by-step explanation:
180° - 35° = 2y°
145° = 2y
145/2 = 50+22+0.5 = 72.5
8yards=24ft
as a fraction=3/24
simplest form=1/8
hope this helps
1. 14 loaves are needed for 63 customers
2. 90 loaves
3. 4.5 loaf
Step by Step:
9/2= 4.5
4.5x4= 18
27/4.5=6
14x4.5=63
I multiplied and divided everything by 4.5 so one loaf of bread is 4.5.
(Correct me if I'm wrong)
I hope this helped! :)
