Mr. Parks spent $96.30 on 3 hats and 6 key chains. a. If each hat cost $15.50, how much did each key chain cost?
Based on the information given the amount that the key chain cost is $8.3
Cost:Let x represent the cost of the key chain
$96.30 = 3($15.50) + x
x = $96.30 - $46.50
x= $49.8
Hence:
Cost per key chain= $49.8/6
Cost per key chain= $8.3
Inconclusion the amount that the key chain cost is $8.3

Find the limit. Use l'Hospital's Rule if appropriate. If there is a more elementary method, consider using it. lim xâ[infinity] x + x2 1 â 5x2
Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Given the expression;
[tex]\lim_{x \to \infty} \dfrac{x+x^2}{5x^2}[/tex]
To find the limit of the function, we need to first divide through by the highest degree if x i.e x² as shown;
[tex]\lim_{x \to \infty} \dfrac{\frac{x}{x^2} +\frac{x^2}{x2}}{\frac{5x^2}{x^2} }\\ \lim_{x \to \infty} \frac{\frac{1}{x}+ 1 }{5}\\As \ x \ tends \ to \ \infty, \ \frac{1}{x} \ tends \ to \ zero. \ Hence;\\ \lim_{x \to \infty} \frac{\frac{1}{x}+ 1 }{5} = \frac{0+1}{5}\\= \dfrac{1}{5}[/tex]
Hence the limit of the function as x tends to infinity is [tex]\frac{1}{5}[/tex]
How many gallons of a 70% antifreeze solution must be mixed with 100 gallons of 30% antifreeze to get a mixture that is 60% antifreeze?
Answer:
350 gallons
Step-by-step explanation:
Let x = number of gallons of 70% solution
100 = number of gallons of 25% solution
Then, x + 100 = number of gallons of 60% solution
0.70x + 0.25(100) = 0.60(x + 100)
0.70x + 25 = 0.60x + 60
0.10x = 35
x = 350 gal
Mix 350 gal of 70% solution with 100 gal of 25% solution to obtain 450 gal of 60% solution.
Answer: Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.

The number of miles driven by a truck driver falls between 300 and 700, and follows a uniform distribution.
a. Find the probability that the truck driver goes more than 650 miles in a day.
b. Find the probability that the truck drivers goes between 400 and 650 miles in a day.
c. At least how many miles does the truck driver travel on the furthest 10% of days?
Answer:
(A) 0.125 probability
(B) 0.625 probability
(C) 660 miles
Step-by-step explanation:
The distance driven by a truck driver daily, falls between 300miles and 700miles and follows a uniform distribution.
(A) The probability that the truck driver goes more than 650 miles a day is:
[700 - 650] / [700 - 300] = 50/400 = 0.125
(B) The probability that the truck driver goes between 400 and 650 miles a day is:
[650 - 400] / [700 - 300] = 250/400 = 0.625
(C) The minimum number of miles the truck driver travels on the furthest 10% of days is given thus:
10% of 400 = 40
Subtract this from the farthest distance;
700miles - 40miles = 660miles

A river flows due south at 1.4 mi/h. In what direction should the swimmer head, at a velocity of 3 mi/h, in order to arrive at a landing point due east of his starting point? (Round your answer to one decimal place.)
Solution:
It is that a river is flowing in the south direction with a speed of [tex]$v_r$[/tex]1.4 mi/h.
A swimmer wishes to cross the river in a horizontal direction so that he lands at a point which is due east of his starting point.
The speed of the swimmer is [tex]$v_s$[/tex] = 3 mi/h
Therefore he has to swim in such a direction that his resultant is in the direction east to his starting point.
Let this angle be θ.
Therefore, from the figure,
[tex]$\sin \theta = \frac{v_r}{v_s}$[/tex]
[tex]$\sin \theta = \frac{1.4}{3}$[/tex]
[tex]$\theta = \sin^{-1}(0.46)$[/tex]
[tex]$=27.4^\circ[/tex]
Therefore, the swimmer has to swim in the northeast direction making an angle of (90+27.4) = 117.4° with the direction of flow of river (i.e. south).
