2,14 4,16 6,18 8,20 f=s+12
Answer:
80
Step-by-step explanation:
Let's write out the equation:
8(20+80/2)/[(54/9+14)/4]
For the first part we get 8(100/2)
Then 50x8
Then 400
For the second part we have (6+14)/4 as we divide 54 by 9. PEMDAS
Then 20/4
Then 5
So our final answer is 400/5 which is 80.
Hope this helps!
Answer:
Step-by-step explanation:
1) Tangent makes 90 degrees with the radius. Hence
a) Angle ABD = 90-angle BDC = 90-61.3 = 28.7
b) Triangle BCD is isosceles since tangents have equal length.
Hence angle BCD = 180-(61.3+61.3) = 57.4
c) Angle BDC = 57.4 (since triangle BCD is isosceles)
d) Angle BAC and Angle BCD are supplementary. Hence angle BAC = 122,6
-------------------------------------------
2) Arc length of minor arc BC = 
b) ARc length of minor arc = circumference -minor arc
= 18.713
---------------------------------------------
3) circumference = pi d =
Answer:
$50
Step-by-step explanation:
When finding sales price you multiply. But here we are finding the original price. So now you do the opposite, divison.
20/.4 = 50
The answer would be 74,000. hope this helps
(3.7 x 10 to the 4th power) x 2 as well = 74,000
