Answer: 9.2
Step-by-step explanation:
Find the linear speed of a point that moves with a constant speed in a circular motion if the point travels along a circle of arc length 7.524 miles in 12 minutes. Round your answer to the nearest tenth.
Answer: 0.6 miles per minute
Note: this is equivalent to 36 miles per hour
===================================================
Explanation:
Imagine that we had a rubber tire and we cut out a section of it. This piece is an arc of the full circle (the original uncut tire). Laying the curved cut rubber piece out flat produces a straight line. If a point moves along this line, then it also moves along the piece of the circle.
To find the linear speed, we just need to divide the arc length over the time value.
In our case, we will compute the following:
linear speed = (arc length)/(time elapsed)
linear speed = (7.524 miles)/(12 minutes)
linear speed = (7.524/12) miles per minute
linear speed = 0.627 miles per minute
linear speed = 0.6 miles per minute
--------------------------
If needed, multiply that by 60 to convert to miles per hour
So we'd say:
(0.6 miles/min)*(60 min/1 hr) = 36 miles per hour
I wasn't sure which units your teacher wanted, so I figured why not show both.
The linear speed of a point that moves with a constant speed in a circular motion is, 0.6 miles per minutes.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The point travels along a circle of arc length 7.524 miles in 12 minutes.
Now, We know that;
⇒ Linear speed = Arc length / Time
Substitute all the values, we get;
⇒ Linear speed = Arc length / Time
⇒ Linear speed = 7.524 / 12
⇒ Linear speed = 0.62 miles per minutes

Step-by-step explanation:
3(-10n + 9) - 3(1 + 8n)= 24
Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
3(−10n+9)−3(1+8n)=24
Step 1: Simplify both sides of the equation.
3(−10n+9)−3(1+8n)=24
(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)
−30n+27+−3+−24n=24
(−30n+−24n)+(27+−3)=24(Combine Like Terms)
−54n+24=24
−54n+24=24
Step 2: Subtract 24 from both sides.
−54n+24−24=24−24
−54n=0
Step 3: Divide both sides by -54.
−54n/-54=0/−54

Using a random sample of 5613 TV households, Acme Media Statistics found that 25.1 % watched the final episode of "When Will it End question mark"
a. Find the margin of error in this percent.
b. Write a statement about the percentage of TV households in the population who tuned into the final episode of "When Will it End question mark"
Answer:
± 1.13432%
between 23.966% and 26.234% households in the population who tuned into the final episode of "When Will it End question mark"
Step-by-step explanation:
Given that:
Sample size (n). = 5613
Proportion (p) = 25.1% = 0.251
Margin of Error can be obtained using :
MOE = z * √p * (1 - p) / √n
Zscore at 95% confidence interval = 1.96
1 - p = 1 - 0.251 = 0.749
Hence,
Margin of Error :
1.96 * √0.251 * 0.749 / √5613
1.96 * (0.4335885 / 74.919957)
= 0.0113432
= ± (0.0113432) * 100%
= ± 1.13432%
B.) between (25.1 - 1.134)% = 23.966% and 25.1 + 1.134)% = 26.234% households in the population who tuned into the final episode of "When Will it End question mark"
Margin of Error (MOE) is a function of the critical value. We will choose a confidential interval of 95 %.
Solution is:
a) MOE = 0,011
b) We can affirm with 95 % of confidence that the porcentage of TV households in the population watching th final episode of " When ...
would be between 25,1 - 0,011 and 25,1 + 0,011
In our question we got:
Sample size n = 5613
p = 25.1 % ( positive events expressed as porcentage )
q = 1 - p q = 1 - 0,251 q = 0,749
According to the size of the sample, and the fact that
q×n and p×n are both q×n > 10 p×n > 10
We are in condition to apply the approximation of the binomial distribution to normal distribution and use table z scores
CI = 95 % then confidence level α = 5 % α/2 = 0,025 and fom z-table we get the critical value
z(c) = 1,96
Now to find MOE
MOE = z(c)×√(p×q/n) ⇒ MOE = 1,96 × √ ( 0,251×0,749)5613
MOE = 1,96 × 0,005787
MOE = 0,011

What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given expression as :
⇒ [tex]4\dfrac{2}{7} + 2\dfrac{9}{14}[/tex]
⇒ (28 + 2)/7 + (28 + 9)/14
⇒ 30/7 + 37/14

Answer:
Option C: One solution
Step-by-step explanation:
5x + 6 = 2 + 3x
Subtract 3x from both sides;
2x + 6 = 2
Subtract 6 from both sides;
2x = -4
Divide both sides by 2;
x = -2
