Answer:
79
Step-by-step explanation:
see which ones are vertical to each other and since they are vertical to each other they are the same degree then and all of the numbers you already have and the answer from that subtract it from 360 and them divide it by 2 .
64+64=128
37+37=74
128+74=202
360-202=158
158÷2=79
the second one hope this helps
19/20= 0.95
Divide 19 and 20 to get your answer:)
Step-by-step explanation:
Let x=distance traveled on 20 gal
One approach is to set up a simple ratio: 15 is to 240 as 20 is to x and this is written as follows:
15/240=20/x cross multiply (actually we are multiplying both sides by 240x)
15x=240*20=4800 divide both sides by 15
x=320 mi------------------------------------distance travelled on 20 gal
Another approach would be to determine the mileage the car gets in miles/gal:
If the car goes 240 mi on 15 gal, then it goes 240/15 or 16 mi on 1 gal.
Soooooooooo our car gets 16 mi/gal and it can go 16*20 or 320 mi on 20 gal
