Formula to find circumference is ;
Since the given circumference is 30 pi then,
30 pi = 2 pi radius.
30 = 2 radius
radius = 30/2
radius = 15
The radius is 15 for a circle tha has circumference of 30 pi
If you have to pay full price for the first bag then there is no discount off the first bag purchased for 10 dollars. If you get 50% off on the second bag then the second bag will cost you five dollars. So that mean you would have to pay 15 dollars for both bags instead of 20 dollars. So your discount on the entire purchase of two bags would be 25% of that purchase.
Answer:
The measures of the angles are 65° and 80°
Step-by-step explanation:
One of the angles is 35°
We know that the other two angles have a difference of 15°
With this knowledge we can write an equation.
2x symbolizes the two angles
+15 symbolizes the difference between the two angles
145 = 2x + 15
145 - 15 = 130
2x = 130
x = 65
65 is the size of one of the angles.
Next, we add 15 to 65 and we get 80
80 is our second angle
Answer:
4 x (7-x)
Step-by-step explanation:
4 times (multiply) the difference (subtraction) of 7 and a number (seeing as how you don't know that number use a variable, x)
=1.3+0.1sqrt29, 1.3-0.1sqrt29
