The formula to find circumference is 2(3.14)r
For this problem, first you take half of the diameter to get radius. Then, putting this into the formula, you get 2(3.14)(6) = 37.699
48 = 2*2*2*2*3
84 = 2*2*3*7
Looking for common factors we get the GCF to be 2*2*3 = 12
Its B
Okay, you now a triangle has 180º degrees and to add to 180º, you have to add all the numbers you have like this:
2x+x+90 (the box is 90º)=180º; add like terms like 2x+x
3x+90=180; cancel 90 by subtracting it and also subtract 90 from 180
3x=90;divide 3 to isolate x and also divide 90/3
x=30 :)
You can use compatible numbers to estimate quotient because they are easy to compute with mentally.
Hope this helps.
Answer:
$131.25
Step-by-step explanation:
Take the $175 price and divide it by 0.25, which is the decimal version of 25%. You should get 43.25 which is 25% of 175. Then subtract 43.25 from 175 to get the final answer of $131.25 for the CD player if Martin buys it on Wednesday.
