2 and 11/100. I think that's as simple as it gets in a mixed number form
Answer:
the radius of a circle = 28.01 cm
Step-by-step explanation:
circumference of a circle = 2 π r
given: circumference = 176 cm
find: radius (r)
plug in values into the formula
176 = 2 π r
r = 176 / 2 π
r = 28.01 cm
therefore the radius of a circle = 28.01 cm
Lets make a proportion with the information we know. For every 1000, 8 of tax is paid.
8/1000
Then, use the rest of the information to make another proportion. We don’t know how much the tax is, so let’s call it x.
x/150000
Set the equations equal to each other
8/1000=x/150000
Cross multiply
1000x=1200000
Divide by 1000 on both sides
x=1200
The teacher will need 10 packages of markers. If 8 markers to a package, 10 packages= 80 markers. If 25 students shall have 3 markers each, that comes to equal 75. So the teacher needs 10 packages and will have five left over.
D=110
t=50
r=x
solution
110=50x
x=110/50
x=1hr. 20mins
or
x=1 X 20/60
x=1 1/3 hr
