Answer:
56.02 dollars
Step-by-step explanation:
Wanted x, the price before taxes and tip.
sales tax: x * 0.11
+
tip on sales tax: x * 0.11 * 0.2
+
tip on price: x * 0.2
= 0.332x
= 18.6 (presumption)
Therefore,
x = 18.6/0.332 = 56.02

Let Sarah's age be s and Antonio's age be a.
According to your question,
2a + 3s = 34
s = 5a
substituting the value of s in eq. 1,
2a + 3(5a) = 34
= 2a + 15 a = 34
17a = 34
thus, a = 34/17 = 2
substituting the value of a is s,
s = 5(2)
= 10
Thus, Sarah's age is 10 years and Antonio's age is 2 years.
Answer:
1571 in
Step-by-step explanation:
Given data
Diamter= 25 in
radius= 25/2= 12.5in
Circumference= 2πr
substitute
C=2*3.142*12.5
C=78.55in
In 1 revolution the bike will travel 78.55in
in 20 revolutions the bike will travel
=78.55*20
=1571 in
I think the probability is .421
