15/20 in it's simplest form is 3/4. You have to divide by 5. 15 divided by 5 is 3 and 20 divided by 5 is 4. Hope i helped. Have a nice day.
Answer: A
Step-by-step explanation: put it into point slope-form
y-ysub1=m(x-xsub1)
m=slope=(-2-3)/(2-(-1))=-5/3
ysub1 is 3 and xsub1 is -1
so substitute: y-3=-5/3(x-(-1))
y-3=-5/2(x+1)
Answer:
Obtuse triangle.
Step-by-step explanation:
Obtuse = angle that is bigger than 90°
Ok so this can get tricky, it is basically just asking for you to perform many unit conversions. I'll try to simplify it for you here while still maintaining the explanation. If you have any questions about this process feel free to message me.
3 yards = ____ miles (conversion factor is 1760 because there are 1760 yards in a mile)
3/1760 = 0.017 miles,
Now we just need to convert seconds to hours.
1 second is how many mins, then how many mins in an hour?
360 seconds in an hour.
Ok now we just need to combine these two pieces of info,
0.017/360 = 4.72222 miles per hour. Thus 4.72 is the answer.
You have to know the formula for the volume of a cone.
In high school, there's no other way.
Volume of a cone = (1 / 3) π (radius)² (height)
Volume = (1 / 3) π (12 inches)² (15 inches)
Volume = 720 π = 2,261.95 cubic inches
Rounded to the nearest cubic inch, that's<u> 2,262 cubic inches</u>.
