40 = 0.5r
40/0.5 = r
80 = r
just divide the number in front of the r so that you can figure it out
Answer:
The radius of the inner circle is 14 ft. Since the outer circle is 3 ft more than the inner circle, its radius is 17 ft. The circumference formula is 2(pi)radius (or 2(22/7)17 in this case). The circumference of the outer circle is 106.85 ft (or 106.9 if rounding). To find the difference, you would subtract the smallest FROM the greatest:
106.85 - 88 = 18.85 ft (or 18.9 if rounding)
Answer:
A
Step-by-step explanation:
let's try A. 3(3)+2=9+2=11
11=11
So A is right
Answer:
3.90 meters.
Step-by-step explanation:
Since Amy needs ribbon for her art project, and she plans to buy 3.84 meters of that material, but the store only sells said product by the tenth of a meter, in order to get closer to the desired size she will have to buy 39 pieces of 10 cm (one tenth of a meter), that is, she must buy 3.90 meters, of which there will be 6 centimeters of the product left over.
Answer:
I just solved a question similar to this
Let's understand it
It's saying she got 660 or it is that her weekly pay is 660
So now let weekly pay which is P be 660
Hence the formulae is given
It's 480 + 18 (h – 30) = 660
Now its just boring calculation
If you mark it brainleist I will do the calculation for you wink wink
Never mind
480 + 18 (h – 30) = 660
18 (h – 30) = 660-480
18 (h – 30) = 120
(h – 30) = 120/18
(h – 30) = 6.6
h = 6.6+30
h= 36.6
So dam the Judy lady worked for 36.6 hours
