The rubber track for a toy digger goes around four circular wheels of diameter 8 cm, as shown. (b) Calculate the length of the rubber track that goes around the four wheels. Give your answer correct to one decimal place.
Answer:
73.1 cm
Step-by-step explanation:
In the drawing, the rubber track is in black and the wheels are in light gray.
As we can see in the figure, the rubber track will have a length of two halfs of a circunference of radius 8 cm plus six diameters of 8 cm. So the total length is:
Length of rubber track = pi * 8 + 6 * 8 = 25.13 + 48 = 73.133 cm
Rounding to one decimal place, we have that the length is 73.1 cm
This question is incomplete because it lacks the diagram of the 4 circular wheels.
Find attached to this answer the appropriate diagram
Answer:
100.5cm
Step-by-step explanation:
The formula to be used in this calculation is the circumference of a circle.
The circumference of a circle can be defined as the actual length of a circle when it is stretch out(opened up) or the distance around a circle.
The formula for the circumference of a circle is given as 2πr where r = radius of the circle
Or πD where D = Diameter of the circle
In the question, we are given the diameter of the circle = 8cm
So we use the Formula
= πD
The length of the rubber track around one wheel is
= π × 8cm = 25.132741229cm
From the attached diagram, we can see we have 4 wheels.
The length of the rubber track that goes around the four wheels is calculated as
4 × 25.132741229cm = 100.53096491cm.
Approximately to one decimal place = 100.5cm
Therefore, the length of the rubber track that goes around the four wheels to one decimal place is 100.5cm

The value of g is 12.8, the solution of the equation.
Here, we have,
The equation you provided is:
g/4 = 3.2
To solve for the value of g, we can multiply both sides of the equation by 4 to isolate g:
4 * (g/4) = 4 * 3.2
The 4 on the left side cancels out with the 4 in the denominator, leaving us with:
g = 4 * 3.2
Multiplying 4 and 3.2 gives us:
g = 12.8
Therefore, the value of g is 12.8.

STRUCTURE Write the ratio of the side lengths of the two cubes described in simplest form. a. The volumes of the two cubes are 270x cubic inches and 32x2 cubic inches. b. The surface areas of the two cubes are 6x4 square feet and 6(x + 1) square feet.
Answer:
a) [tex]2.036x^-\frac{1}{3}[/tex]
b) [tex]\frac{x^2}{\sqrt{x+1} }[/tex]
Step-by-step explanation:
For a cube, all the sides are equal. Let the length of each side be L
a) The volume of a cube (V) = L³
For the first cube:
V = 270x in³
270x = L³
L = ∛(270x) = [tex]6.463x^\frac{1}{3}[/tex]
For the second cube:
V = 32x² in³
32x² = L³
L = ∛(32x²) = [tex]3.175x^\frac{2}{3}[/tex]
Ratio of length = [tex]\frac{6.463x^\frac{1}{3} }{3.175x^\frac{2}{3} }=2.036x^-\frac{1}{3}[/tex]
b) The surface area of a cube (s) = 6L²
For the first cube:
s = 6x⁴ ft²
6x⁴ = L²
L = √6x⁴= 2.45x²
For the second cube:
s = 6(x + 1) ft²
6(x + 1) = L²
L = √6(x + 1)= 2.45√(x + 1)
Ratio of the length = [tex]\frac{2.45x^2}{2.45\sqrt{ (x + 1)}} =\frac{x^2}{\sqrt{x+1} }[/tex]

A fish tank holds 832 gallons but is leaking at a rate of 5 gallons per week. A second fish tank hose 1040 gallons but is leaking any rate of 9 gallons per week after how many weeks with the amount of water in the two fish tanks me the same
Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52
A 12-tooth gear on a motor shaft drives a larger gear having 42 teeth. If the motor shaft rotates at 700 rpm, what is the speed of the larger gear? The speed of the larger gear is nothing rpm.
Answer:
203 rpm
Step-by-step explanation:
The speed of the larger gear can be calculated using the following equation:
[tex] v = \omega*R [/tex]
Where:
ω: is the angular velocity of the motor = 700 rpm
R: is the gear ratio
The gear ratio is the following:
[tex] R = \frac{n_{(a)}}{n_{(b)}} [/tex]
Where:
n(a): is the number of teeth on the small gear = 12 teeth
n(b): is the number of teeth on the larger gear = 42 teeth
The gear ratio is:
[tex]R = \frac{12}{42} = 0.29[/tex]
Now, the speed of the larger gear is:
[tex]v = \omega*R = 700 rpm*0.29 = 203 rpm[/tex]
Therefore, the speed of the larger gear is 203 rpm.

C(x) = -2401 - 140 + 1,400
S(s) = 4503 + 100
Which function represents Betty's total account balance. T(x)?
Answer:
T(x) or total account balance = C(x) + S(x)
Step-by-step explanation:
where = C(x) = -2401 - 140 + 1,400
and
S(x) = 4503 + 100
This implies that:
C(x) = 3,661
S(x) = 4,603
Therefore, T(x) 3,661 + 4,603 = 8,264
T(x) is the total account balance or the addition of the balances of checking and saving accounts.
C(x) is the checking account balance.
S(x) is the saving account balance.

The answer on the top is the best line for a line of best fit because...
Step-by-step explanation:
there is a noticeable correlation in the first graph- a positive one. The line of best fit should have about the same amount of line plots on the top than on the bottom. Also, there can be a few line plots that is touching the line of best fit as well. Those line plots will be about the middle of the data and provide a good guideline to make your line of best fit the most accurate. The second graph is pretty scattered and doesn't have a clear correlation therefore having no correlation. Hope this helps!!

The tangent of angle X is 2.246.
Work out the size of angle X.
Give your answer to the nearest degree.
____ °
Tangents are slopes, and there are two angles with the same slope that are 180 degrees apart, not to mention an infinite number of coterminal brethren all with the same tangent. So this question is a bit ambiguous.
Let's assume they want the principal value of the inverse tangent, between -90 degrees and +90 degrees. A tangent bigger than 1 means it will be between 45 and 90 degrees.
tan x = 2.246
x = arctan 2.246 = 66.00 degrees

The inverse of the function f(x) = {x+
+ 10 is shown
h(x) = 2x-0
What is the missing value?
A. 1
B.5
C.10
D.20
Answer:
D
Step-by-step explanation:
f(x) = x + 10
Replace f(x) with y.
y = x + 10
Now, remember that in an inverse function you flip the x and y, so
x = y + 10
Solve for y
y = x - 10
because its 2x... we must multiply by 2.
2y = 2x - 20
Original equation:
h(x) = 2x - 0
h(x) is 2y..

replacement, a white marble?
5/44
31/44
5/48
Answer:
5/44
Step-by-step explanation:
3 red, 4 blue, and 5 white = 12 marbles
P(red) = number of red / total
= 3/12 = 1/4
no replacement
2 red, 4 blue, and 5 white = 11 marbles
P(white) = number of white / total
= 5/11
P(red, no replacement, whit) = 1/4*5/11 = 5/44
