working together Alberto and Amanda can paint a fence in 4.12 hours. had she done it alone it would have taken Amanda 10 hours. find how long it would take Alberto to do it alone. A) 6.75 B) 5.02 c) 7.54 D)7.01
Answer:
D) 7.01
Step-by-step explanation:
The rates of doing work, in terms of jobs per hour, will add when the two painters are working together. If A represents Alberto's time to do the job alone, we have ...
1/4.12 = 1/10 + 1/A
(Jobs per hour is the inverse of hours per job.)
A = 1/(1/4.12 -1/10) ≈ 7.0068 ≈ 7.01
It takes Alberto 7.01 hours to do the job alone.
if x=2⅓-2, then find the value of x³+6x²+12x

Which of the following statements does not represent the same value as the others?
a) the distance between 0 and −9
b) the absolute value of negative 9
c) the opposite of 9the absolute value of 9
The statement that does not represent the same value as the others is 'the opposite of 9'
What is an absolute value of number?"It is the actual distance of the number from zero."
What is opposite of a number?"The opposite of number is a value which is an additive inverse of number.""The opposite of number 'a' is '-a'."For given question,
We need to find the statement which does not represent the same value as the others.
We find the value for each statement.
a) the distance between 0 and 9
The distance between 0 and 9 is 9.
b) the absolute value of negative 9
We know, |-9| = 9
So, the absolute value of -9 is 9
c) the opposite of 9
The opposite of 9 is -9.
d) the absolute value of 9
|9| = 9
So, the absolute value of 9 is 9.
Therefore, the statement that does not represent the same value as the others is 'the opposite of 9'

A field in the shape of a square has an area of 8,100 square feet. How can you determine the length of one side of the field?
To determine the length of one side use the formula for the area of square. As a square is equal on all four sides, finding one length results in any of the four. Solve using the formula and you receive your answer of 90.
A = s²
8100 ft² = s² (set up formula)
√8100 ft² = s² ( get s alone by squaring both sides)
90 ft = s (answer)
We can conclude that the side of the given square with an area of 8100ft² is 90ft.
What is a square?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length. A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90-degree angles.So, the area of the square is 8100ft².
Formula: s²So, we know that: 8100 = s²Now, calculate for s as follows:
s² = 8100s = √8100s = 90ftTherefore, we can conclude that the side of the given square with an area of 8100ft² is 90ft.

a ball is dropped from rest from a high window of a tall building and falls for 4 seconds. Neglecting air resistance. The final velocity of the ball is m/s. (g=-9.8m/s 2) the first person to answer me gets the brainliest
Step-by-step explanation:
v=u+at
v=0+9.8m/s2 ×4s
v=39.2 ms-1
Final velocity; v = -39.24 m/s
In free fall, the motion is in the direction of gravity.
Formula for final velocity in free fall is;
v = u + gt
(g is negative)
We are told the ball is dropped from rest.
Thus;
Initial velocity: u = 0 m/s
Time; t = 4 secs
Acceleration due to gravity; g = -9.81 m/s²
Thus, Plugging in the relevant values, we have;
v = 0 + (-9.81 × 4)
v = -39.24 m/s
Final velocity; v = -39.24 m/s

You have to put in at least 20 hours a week at the Sippy Drink to keep your job there. You can't work more than 40 hours a week. how many hours should you work at each job to earn the maximum amount of money a week?
Answer:
5hours
Step-by-step explanation:
1 week =7 days
10 hr +20hr = 30 hrs
If you work 4hrs a wee k you will achieve only 28hrs of work so you will have to work for 5hrs to achieve 35hrs of work which is still within the bracket of 40hrs of work
In each job you will work for 2hours 30

Supplementary angles are angles that add to 180 degrees.
Let's examine the answer choices.
A. ∠8 and ∠7
⇒ These angles are on a straight line together, so they are supplementary.
B. ∠5 and ∠1
⇒ These angles have no relation to each other. They are on different lines that are not parallel.
C. ∠7 and ∠4
⇒These angles also have no relation to each other.
D. ∠2 and ∠4
