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.
Answers
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.

Dante rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 87 cents for each mile driven. Dante had to pay $218.22 when he returned the truck. For how many miles did he drive the truck?
Answers
Say John traveled two miles. He had to pay $18.99 for the base charge, plus $.75(2), which came to $1.50, for a total of $20.49.
However, we are given his total and instructed to calculate the miles.
18.99 + .75m = 199.74
-18.99 -18.99
.75m = 180.75
.75 .75
m = 241

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:

You have $100 in a savings accoun and save an additional $40 each week. Your friend has $80 in a savings account and saves and addtional $10 each week.
Answers
The number of weeks for your friend's savings to be same as your savings does not exist
How to determine the number of weeks?The given parameters are:
Your savings account
Initial amount = $100
Weekly savings = $40
Your friend's savings account
Initial amount = $80
Weekly savings = $10
The equation that represents the amount in the account after w weeks is represented as
Amount = Initial amount + Weekly savings x Number of weeks
This gives:
You: Amount = 100 + 40x
Your friend = 80 + 10x
The above equations are linear equations
When the amounts are equal, we have
100 + 40x = 80 + 10x
This gives
30x = -20
Divide
x = -2/3
The number of weeks cannot be negative
Hence, your friend's savings will never be up to your savings

what is the prime fractorization of 42?
Answers
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;

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 ...

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.
Answers
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|.
