How do I convert 65 mi/hr to centimeters per minute
In the metric system, centimeters per minute (cpm) represents speed or velocity. It counts the centimeters that are covered in a minute.
65 mi/hr to 174346 centimeters per minute.
How to convert Miles Per Hour to Centimeters Per Minute (mi/h to cm/min ?$1 mi/h = 2682.2346355307 cm/ min.
65 × 2682.2346355307 cm/min = 174345.2513095 Centimeters Per Minute.
Always check the results; rounding errors may occur.
The base unit of [speed] (meters per second), 1 Miles Per Hour (mi/h) exists equivalent to
0.44704 meters-per-second,
while 1 Centimeters Per Minute (cm/min) = 0.000166667 meters-per-second.
65 Miles Per Hour to common speed units
65 mi/ h = 65 miles per hour (mi/h)
65 mi/h = 1.0833333333333 miles per minute (mi/m)
65 mi/h = 174346 centimeters per minute
Therefore, the correct answer is 174346 centimeters per minute.
The base unit for speed is meters per second (Non-SI Unit)

(If the equation is not linear, enter NONLINEAR.)
City A has three times as many people as cities B and C combined
Answer:
x -3y -3z = 0
Step-by-step explanation:
You want to write "City A has three times as many people as cities B and C combined" as an equation in standard form, letting x, y, z, w represent the populations of cities A, B, C, D, respectively.
TranslationThe populations of cites B and C combined can be expressed by ...
y +z
Three times the combined population is then ...
3(y +z)
This is equal to the population of city A, so we can write ...
x = 3(y +z)
Standard formThis equation is in standard form when all of the variable terms are on one side of the equal sign, and the expression is simplified.
x -3(y +z) = 0 . . . . . . . subtract the right side expression
x -3y -3z = 0 . . . . . . . eliminate parentheses; standard form

what is the prime fractorization of 42?
First I will define what prime factor means
Prime factors of 42 are the factors of 42 that are prime
Prime numbers are those numbers that have two factors; 1 and itself
Factors of 42 are those numbers that can go into 42 without remainder
So let's list out the factors of 42, they are;
Factors of 42 = 1, 2, 3, 6, 7, 14, 21 and 42
Now among these factors, we will list out the ones that are prime, they are the prime factors
That is;
Prime factors of 42 = 2, 3, and 7
To express 42 as a product of it's prime factors, we have 2 ways of doing this
The first method is; To keep dividing 42 by the smallest prime factors
42 = 2 x 3 x 7
The second method is;
Therefore, the prime factorization of 42 = 2 x 3 x 7
The prime factorization of 42 is 2 × 3 × 7.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The positive pair factors of 42 are (1, 42), (2, 21), (3, 14), and (6, 7).
The negative pair factors of 42 are (-1, -42), (-2, -21), (-3, -14), and (-6, -7).
The 42 factors that are prime are known as the prime factors of 42.
Prime numbers are those with just themselves and factor 1 as their factors.
The numbers that can round to 42 without leaving a remainder are known as 42 factors. Let's enumerate the 42 factors, which are as follows:
1, 2, 3, 6, 7, 14, 21, and 42 are factors of 42.
We shall now list the prime factors among them, they are the prime factors. which is;
42 has prime factors of 2, 3, and 7.

A rabbit is moving in the positive x-direction at 1.50 m/s when it spots a predator and accelerates to a velocity of 12.1 m/s along the positive y-axis, all in 2.20 s. Determine the x-component and the y-component of the rabbit's acceleration. (Enter your answers in m/s2. Indicate the direction with the signs of your answers.)
Answer:
Step-by-step explanation:
First we have to consider the initial and final velocities to calculate the average acceleration:
v_i= - \Big[ 1.10\frac{m}{s}\Big]\widehat{i} \\ v_f= \Big[ 11.5\frac{m}{s}\Big]\widehat{j} \\ \implies \Delta v=v_f-v_i \\ \implies \Delta v= [ 1.10\frac{m}{s}]\widehat{i} +[ 11.5\frac{m}{s}]\widehat{j} \text{ in an average time } \Delta t=1.40\,s.v

Anders discovered an old pay statement from 12 years ago. His monthly salary at the time was $2800 versus his current salary of $4970 per month. At what (equivalent) compound annual rate has his salary grown during the period
The (equivalent) compound annual rate at which Anders' salary has grown during the 12 years is 4.9%.
What does the compound annual rate signify?The compound annual rate is the equivalent rate of interest at which the present value of money grows to attain a future value.
At a 4.9% compound annual rate, Anders' salary has been growing by adding the growth amount to the initial salary and compounding both the principal and subsequent interest amounts until 12 years.
N (# of periods) = 12 years
PV (Present Value) = $2,800
PMT (Periodic Payment) = $0
FV = $-4,971.23
Results:
I/Y (Interest per year) = 4.9%

A quality assurance engineer randomly checks manufactured parts to ensure that they are within 0.002 mm of the desired specifications. If the desired length of the part is 3 mm, then the compound inequality
-0.002
Choose the absolute value inequality that represents the situation.
The value of absolute inequality will be given by 0.002 ≥ |x-3|.
Inequality may be defined as the expression which shows unequal behavior between two entities while absolute inequality expression includes inequality along with an absolute value. For example, |x| > 3, |x| <3, |x| ≤3 or |x| ≥3. Now, let us assume the length of the part in the question as x. Since, the desired length is given as 3mm and also the parts are within 0.002 mm of the desired specifications.
Therefore, the maximum length of the part can be = 3 + 0.002
and the minimum length of the part can be = 3 - 0.002
Therefore, we can write the inequality as
3 - 0.002 ≤ x ≤ 3 + 0.002
⇒ 3 - 0.002 ≤ x and x ≤ 3 + 0.002
⇒ -0.002 ≤ x-3 and x-3 ≤ 0.002
⇒ 0.002 ≥ -(x-3) and x-3 ≤ 0.002 (Because a > b ⇒ -a<-b)
⇒ 0.002 ≥ | x - 3 |
Thus, the required absolute inequality is 0.002 ≥ |x-3|.

A 22-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than four times the length of the first piece. Find the lengths of the pieces.
A 22-inch piece of steel is divided into three parts, the length of 1st 2nd and 3rd piece are 3 inch,6 inch and 13 inch.
Given that,
A 22-inch piece of steel is divided into three parts, the second of which is twice as long as the first and the third of which is one inch longer than the first.
We have to find the parts' lengths.
Let us take, the length of the first piece is x inch.
Then the length of the second piece is 2x.
Then the length of the third piece is 4x + 1 inch.
We know total length of the steel is 22 inch.
We can write as,
x + 2x + 4x + 1 = 22
7x = 21
x = 3.
Then, the length of the first piece is 3 inch.
Then the length of the second piece is 2×3=6 inch.
Then the length of the third piece is 4×3 + 1=12+1=13 inch.
Therefore, the length of 1st 2nd and 3rd piece are 3 inch,6inch and 13 inch.
