Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x

Two pieces of ribbon, one with a length of 63 inches and another with a length of 42 inches are cut into pieces of equal length without remainder. Find the greatest possible length that the pieces can be.
Answer
224 over 567
Step-by-step explanation:
Answer:
21
Step-by-step explanation:
the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.
The lowest common multiple of 63 is 3. 63/3 = 21
The lowest common multiple of 42 is 2 = 42/2 = 21

Please Help!!! A bicycle has wheels 28 inches in diameter. tachometer determines that the wheels are rotating at 180 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road.
Answer:
402.336 meters per minutes
Step-by-step explanation:
revolutions per minute = speed in meters per minute / circumference in meters.
Diameter = 28 inches
Circumference of the wheel = 2πr
r = Diameter/2 = 28/2 = 14
Circumference = 2 × π × 14
= 87.964594301 inches
Approximately = 88 inches
Note that:
1 inch = 0.0254 metre
88 inches = x
x = 88 × 0.0254 meters
x = 2.2352 meters
Hence:
Revolutions per minute = Speed in meters per minute / circumference in meters.
Speed = Revolutions per minute × circumference in meters.
Speed = 180 RPM × 2.2352 meters
Speed = 402.336 meters per minutes
Speed of the bicycle traveling down the road = 84π.
It is given that
Diameter of the wheel (2r) = 28 inches, where 'r' is the radius
Speed N(in revolutions per minute) = 180rpm
What is the formula for angular speed?Angular speed ω = [tex]\frac{2\pi N}{60}[/tex]radian per second.
[tex]w= \frac{2*\pi*180 }{60 } = 6\pi[/tex] radian per second
Speed of bicycle V = r*ω
Where,
r= radius of the wheel
[tex]V = 14*6*\pi = 84\pi inches/second[/tex]
Therefore,
speed of the bicycle traveling down the road = 84π.

Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

perfume is sold in two diffrent sizes of bottle.
Answer: get the 2 perfums in the size 50ml
Step-by-step explanation:
80ml is 55 pound
50 ml is 45 pound
2nd is half of 45 pound which is 22.5
the 2 perfum in the size 50 ml with the special price is: 45 + 22.5 = 67.5 now per ml is 0.675 pound per ml i found the price per pound by dividing the ml by the price
for the 80ml the price per ml is 0.6875

1/4
O 1/2
O 1/3
O 1/5
Answer:
1/2
Step-by-step explanation:
So we multiply 2 by 6, and get 12.
Then we multiply 1 by 3, and get 3.
Next we give both terms new denominators
So now our fractions look like this:
12/18-3/18
Since our denominators match, we can subtract the numerators.
12 − 3 = 9
So the answer is:
9/18
So we reduce it:
9/18divided by 3=3/6
so since it’s equivalent we reduce it again
3/6divided by 3 which equals 1/2
and that’s our final answer 1/2
I hoped that this helps :)

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?
Answer: The other point is (17, -6).
Step-by-step explanation:
Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-
[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]
Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).
Let other point be (a,b), then
[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]
hence, the other point is (17, -6).
Convert each radian measure into degrees.
4) 8pi/3
Answer:
[tex]\boxed {\boxed {\sf 480\textdegree}}[/tex]
Step-by-step explanation:
First, remember that π radians is equal to 180 degrees. Therefore, to convert from radians to degrees, multiply by 180/π.
The radian measure given is 8π/3
[tex]\frac {8 \pi}{3} * \frac{180}{\pi}[/tex]
Multiply the fractions. Multiply across the numerator, then across the denominator.
[tex]\frac{8 \pi *180}{3 * \pi}[/tex]
The pi in the numerator and denominator will cancel out.
[tex]\frac{8 *180}{3 }[/tex]
Multiply.
[tex]\frac{1440}{3}=480[/tex]
The radian measure 8π/3 is equal to 480 degrees.
