The smiths counted 11 riders and 26 wheels passing by. There were no unicycles, only bicycles and tricycles with only one rider.

I only one person rode a tricycle - that would leave 23 wheels and you cannot make a complete number of bicycles
If 2 people rode tricycles that would leave 20 wheels which would seat 10 bicyclists.
But that totals up to 12 people

3 people riding tricyles leaves 15 wheels which will not complete a number of bicycles

4 people riding tricycles (4 x 3) leaves 14 wheels for 7 bicyclist and is the answer

4 trike riders (12 wheels) + 7 bike riders (14 wheels) = 11 people and 26 wheels

Find the value of the trigonometric ratio. make sure to simplify the fraction if needed

Answer:

Sin A = o/h

= 9/41

Step-by-step explanation:

since Sin is equal to opposite over hypotenuse, from the question, the opposite angle of A is 9 and hypotenuse angle of A is 41. Thus the answer for Sin A= 9/41

A ball is thrown from an initial height of 2 feet with an initial upward velocity of 18/fts . The ball's height h (in feet) afte

inna [77]

Hello! First insert 6 where the h is located. So we have an equation that looks like the following. $6 = 2 - 18t + 16t^2$

Although you could leave the equation in its original form, I am going to switch it around.
$6 = 2 - 18t + 16t^2$
$16t^2 - 18t + 2 = 6$
Move the 6 to the other side and do the math
$16t^2 - 18t + 2 - 6 = 6 - 6$
$16t^2 - 18t -4 = 0$
Factor and after factoring your T will be as follows
t = $\frac{9}{16} - \frac{\sqrt{145}}{16}$ = -0.1900
t = $\frac{9}{16} + \frac{\sqrt{145}}{16}$ = 1.315
