Answer:
I dont know But maybe the answer is No
Step-by-step explanation:
0.3 is 30% and if 1/10 is 10% then 2/20 must be 10% because 5% is 1/20
so maybe 3/20 is only 15%
I hope this helps :)
Sorry if it dosent i suck at explaining things ; - ;
I'll solve 21, and you then should be able to solve the rest on your own!
Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
Answer:
Step-by-step explanation:
Since there are 360 degrees in a circle, we can set up the following proportion:
The sum of 31/4+42/4= 18.25
<u>Step-by-step explanation</u>:
- The denominators are same.
- Then add the numerators and keep the denominators same.
The sum of (31/4) + (42/4) = (31+42)/4
⇒ 73/4
⇒ 18.25
