8. Sven sells hamburgers at a ballpark. He earns $14.50/h, plus $0.50
for each hamburger he sells.
a) How much will Sven earn in a 3 hour shift if he sells 24
hamburgers?
b) How many hamburgers must Sven sell to earn $120 in a 6.5 hour
shift? (round to the nearest burger)
Answers
Answer:
Part A: $55.50
Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)
Step-by-step explanation:
Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=
($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)
Hence $43.50 + $12= $55.50.
Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75
($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif
$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)
Hence answer is 52 burgers.

A bead is chosen randomly from a cloth bag. If 40% of the beads are spheres, and 30% of the spheres are blue, what's the probability of choosing a blue sphere?
Answers
Answer: 12%
Step-by-step explanation:
To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:
= Probability of sphere * Probability that sphere is blue
= 40% * 30%
= 12%

When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

Answers
1.) Find the slope of the line represented by the table
2.) Find the y-intercept
need help asap
Answers
Answer:
3, 1
Step-by-step explanation:
Slope is rise/run, with the rise being the y increase, and x being the x increase.
Since the run represented is 3, and the rise is 9:
9/3 = 3
The y-intercept is the value of f(x) (which is y) when x = 0
since the equation of the line is:
f(x) = 3x + b
we need to go down 3 units of x since x = 0
3 x 3 = 9
10 - 9 = 1
b = 1
The y-intercept is 1.

The ratio of health club members who use trainers to those who do not
is 2:5. There are 342 members who use trainers. How many members
does the club have?
Answers
Answer:
Step-by-step explanation:
The anwser is 479 - 2:5 as a decimal is .4 , 342 x .4 is 126.8
342+126.8 = 178.8
round it and get 479
By using given ratio, Members does the club have are 1197.
What is ratio?"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."
We have,
Ratio of health club members who use trainers and who do not is 2:5.
Members who use trainers = 342
Members who does not use trainers
= [tex]\frac{342}{2}[/tex]×[tex]5[/tex]
= 171 × 5
= 855
Total members
= 855 + 342
= 1197

What is the approximate distance, in feet, between Padma and the bear?
A
21.2ft
B
75.2ft
C
96.4ft
D
171.6ft
Answers
The approximate distance, in feet, between Padma and the bear will be 75.2 feet. Then the correct option is B.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
James and Padma are on inverse sides of a 100-broad gulch. James sees a bear at a point of discouragement of 45 degrees. Padma sees a similar bear at a point of discouragement of 65 degrees.
Let 'x' be the horizontal distance from bear to Padma. Then the equation is given as,
(tan 45°) (100 - x) = (tan 65°) x
100 - x = 2.1445x
100 = 3.1445x
x = 31.80 feet
Then the approximate distance, in feet, between Padma and the bear will be given as,
cos 65° = 31.80 / d
d = 75.2487
d ≈ 75.2 feet
The approximate distance will be 75.2 feet. Then the correct option is B.
