Tyler has $600 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $233.09. He buys 3 bicycle reflectors for $16.38 each and a pair of bike gloves for $29.13. He plans to spend some or all of the money he has left to buy new biking outfits for $52.48 each. Write and solve an inequality which can be used to determine xx, the number of outfits Tyler can purchase while staying within his budget.
Answers
Answer:
x ≤ 5.5
Step-by-step explanation:
Amount with Tyler = $600
Cost of new bicycle = $233.09
Cost of 3 bicycle reflectors = $16.38 * 3
= $49.14
Cost of bike gloves = $29.13
Cost of biking outfit = $52.48
Number of biking outfit = x
233.09 + 49.14 + 29.13 + 52.48x ≤ 600
311.36 + 52.48x ≤ 600
52.48x ≤ 600 - 311.36
52.48x ≤ 288.64
x ≤ 288.64/52.48
x ≤ 5.5
Number of biking outfit = x
x ≤ 5.5

The perimeter of a rectangular field is 60 m.
What are three possible measurements
of the field? Use dimensions to the
nearest meter.
Answers
Answer:
10m by 20m
12 m by 18 m
14m by 16m
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w)
60 = 2(l+w)
Divide each side by 2
30 = l+w
Let l = 10
Then w = 30 - 10 = 20
Let l = 12 then w = 30 - 12 = 18
Let l = 14 then w = 30 -14 = 16

Answers
Answer:
100
Step-by-step explanation:
It is a rule that for two opposite arcs, with intersecting lines, between them, the average of the arcs is equivalent to the inside angle. Given this, we can say that:
(CF + ED)/2 = angle G
plug values in
(12x+9x+10)/2 = 110
multiply both sides by 2
21x + 10 = 220
subtract 10 from both sides
21x = 210
divide both sides by 21
x=10
Plug this into DE

.'. Missing number = 15 + (1 + 2 + 3 + 4) = 25.
Answer: 25!
Step-by-step explanation:
5, 6, 9, 15, ?, 40
5 + 1 = 6

Twice a number (z) added to 21 is equal to 9 times the number added to 7. What is the number?
Answers
Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2

A ball is dropped from a height of 20 feet. The ball rebounds to 80% of its previous height. Let n represent
the number of bounces of the ball.
a. h=20(.20)^n
b. h=20(.80)n
c. h=20(.80)^n
d. h=20(1.80)^n
Answers
Answer:
[tex]H=20(0.8)^{n}[/tex]
Step-by-step explanation:
So, lets just go over this step by step and make sense of it.
20 clearly must be what we start with, and as you see in your answers, all of them have that as the number you multiply the parethese by.
Its what next that we dont know about.
We know that the ball rebounds 80% of its previous height.
It for sure cannot be a or d because a would mean that it would only rebound 20% of its height, and d would mean that it rebound 180% of its height.
Its now between b and c.
Lets just think about it.
Pull out your calculator or pull it up on your electronic. Multiply 10 by 0.9. This will get you 9. Multiply 9 again by 0.9, and youll get 8.1.
What did we actually do there? We did 10*0.9^2
Pull out your calculator again and try 10* 0.9^2. Youll see that 0.9 squared is 0.81. This times 10 is 8.1, and that is exactly what you got before.
Understanding this, it is clear that we must use an exponent to fidn future values.
In answer b, it shows that you can just multiply by n.
In answer c however, it uses n as an exponent, which is the correct thing to do.
So c is your answer.
The actual formula for this is: [tex]first_.term(change)^t^e^r^m ^[/tex]
The first term in this case is the first height, which is 20. The change is a rebound of 80%(0.8).
The term is just n, but in most problems n is time.
Hope this helps!

Answer:
The function is linear because the points are not in a straight line.Points that lie along the same line are said to be "collinear" and collinear points must have the same slope between any pair of points.

The answer will be option 1 :-
The function is linear because the points are not in a straight line.Well, for a straight line the points formed are known as collinear points & the points given ->( -1, –4), (0, 1), (1, 4) are not collinear as they are not formed in the same line of the graph. Also, graphs have straight lines. From this we can see that none of the other options work. Hence, option 1 is the correct answer (✓).

What is the measure of angle 4 if angle 1 = 76 degrees, angle 2 = 27 degrees and angle 3 = 17 degrees
Answers
Answer:
Step-by-step explanation:
∠1 + ∠2 + ∠3 + a = 360 {Sum of all angles of quadrilateral}
76 + 27 + 17 + a = 360
120 + a = 360
a = 360 -120
a = 240°
a + ∠4 = 360
240 + ∠4 = 360
∠4 = 360 - 240
∠4 = 120°

John works a fortnightly wage of $750.00. If his basic week is 40 hours. what is his: Weekly wage basic rate and basic fortnight??
Answers
Answer:
Basic wage rate = $9.375 per hour
Step-by-step explanation:
Given :
Fortnight wage = $750
Basic week, hours worked per week = 40 hours
Weekly basic wage rate :
Fortnight = 2 weeks
Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375
Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour
