The radius of the wheel is 140.06 inches
Since the wheels on a truck are turning at 630 revolutions per minute as the truck travels at 50 miles per hour, we need to find the distance mover per revolution.
Distance moved per revolution by wheelSo, distance moved per revolution = speed of truck ÷ revolutions per minute
Speed of truck = 50 miles per hour
Converting to inches per min, we have
= 50 × 63360 in/hr ÷ 1 hr/60 min
= 3168000 in/60 min
= 52800 in/min
revolutions per min = 60 rev/min
So, substituting the variables into the equation, we have
distance moved per revolution = 52800 in/min ÷ 60 rev/min
= 880 in/rev
Circumference of the wheelSince the distance moved per revolution is the circumference of the wheel, C we have that
C = 2πr where r = radius of wheel
Radius of the wheelMaking r subject of the formula, we have
r = C/2π
Since C = 880 in
Substituting the value of the variable into the equation, we have
r = C/2π
r = 880 in/2π
r = 440 in/π
r = 140.06 in
So, the radius of the wheel is 140.06 inches

Noah has collected $50 by selling lemonade and muffins. He sold $10 worth of muffins. He sold
each cup of lemonade for $2. How many cups of lemonade did he sell?
Answer:
5 cups of lemonade
Step-by-step:
Let's first make an equation from the question.
$10 = muffins (x)
$2 = cups of lemonade (y)
$10x + $2y = $50
x= 4
y= 5
Plug in the numbers:

x^5=243
what is the formular to the equation.
Answer:
x = 3
Step-by-step explanation:
x^5 = 243
Take the fifth root of each side which is the same as raising each side to th 1/5 power. Also, 243 = 3^5.
x^5 = 3^5
(x^5)^(1/5) = (3^5)^(1/5)
x = 3
Answer:
3
Step-by-step explanation:
x^5= 243
I guess we're looking for x
so what we do is just find the fifth root of 243
and that's 3

turn 55% in to fraction
Answer: Your answer is 55% = 11 / 20
Hope this helps!
Answer:
11/20
Step-by-step explanation:
Step 1: We represent the given number as a fraction by dividing it by 100.
Hence, we write it as 55/100.
Step 2: Simplify the fraction by using common factors of numerator and denominator.
Now, 55% can be written as 55 / 100.
On simplifying the above fraction:
55 / 100 = 11 / 20 [Dividing numerator and denominator by their greatest common factor, that is 5.]
Therefore, 55% can be represented as 11/20 in fractional form.

A rectangle has a
perimeter of (12x +
8y). If one side of
the rectangle is (4x
– 2y), write an
expression of the
other side
Answer:
3x + 6y
Step-by-step explanation:
so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y

Inscribed Angles
if angles ABC measures 70 what does angles ADC measure?
Answer:
35 degrees
Step-by-step explanation:
Assuming B is the center of the circle, the measure of arc AC is 70 degrees since the measure of a central angle is equal to the measure of the arc it intercepts.
This means that by the inscribed angle theorem, which states that the measure of an inscribed angle is half the measure of the arc it intercepts, the measure of the desired angle is 35 degrees.

Answer:
Heptagon = 84 ft²
Octagon = 186 yd²
Triangle = 48√3 m²
Step-by-step explanation:
[tex]\textsf{area of a regular polygon}=\dfrac12ap[/tex]
where:
[tex]a[/tex] = length of apothem[tex]p[/tex] = perimeterHeptagon
a = 5.0 ft
p = 33.6 ft
⇒ area = 1/2 x 5.0 x 33.6 = 84 ft²
Octagon
a = 7.5 yd
p = 8 x 6.2 = 49.6 yd
⇒ area = 1/2 x 7.5 x 49.6 = 186 yd²
Triangle
Formula for the apothem of an equilateral triangle :
[tex]a=\dfrac{s}{2\sqrt{3}}[/tex] where [tex]s[/tex] = side length
a = 4, so:
[tex]4=\dfrac{s}{2\sqrt{3}}[/tex]
[tex]\implies 8\sqrt{3}=s[/tex]
Now we know the side length, we can calculate the perimeter (p):
p = 3 x 8√3 = 24√3
⇒ area = 1/2 x 4 x 24√3 = 48√3 m²

What is the slope of the line that passes through the points (6,−5) and (-6, -5)
Answer:
0
Step-by-step explanation:
Slope can be conceptualized as rise over run.
To get rise, you can see the difference between the two 'y' coordinates. In this case, it's 0 (-5 and -5). At this point, since the numerator of our [tex]\frac{rise}{run}[/tex] fraction is 0, you know it's just gonna be 0 no matter the value of the run.
Need help finding the solution for this linear equation
Answer:
x = -3
y = 7
Step-by-step explanation:
4y + 2 = 30
x - 4y = -31
Simplify the first equation by subtracting 2 from both sides:
4y = 28
Divide both sides by 4
y=7
Plug 7 in for y to solve for x:
x - 4(7) = -31
x - 28 = -31
Add 28 to both sides
x=-3
(x,y)=(-3,7)

Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
