A painting crew reported that a job is 3/5 completed. what fraction of the job remains to be done.

Answers

Answer 1

Answer: If we know that a job is 3/5 completed, that means that 3 out of 5 has been completed which means that 2 out of 5 has not been completed.

Answer 2

Answer:

The required fraction of the job that remains to be done is 2x / 5.

Given that,
A painting crew reported that a job is 3/5 completed. what fraction of the job remains to be done is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Let the whole fraction of the job be x.
A painting crew reported that a job is 3/5 completed = 3/5x
The job remains to be done = x - 3/5x
= 2x / 5

Thus, the required fraction of the job that remains to be done is 2x / 5.

Find the discriminant for this equation. x2 + 3x + 1 = 0

Answers

Answer:

Step-by-step explanation:

if ax^2 +bx + c ====>discriminant formula is b^2 - 4ac from the quadratic formula

x2 + 3x + 1 = 0

Then;

a=1

b=3

c=1

b^2 - 4ac = 3^2 -4*1*1

A rectangular blanket's perimeter is 210 inches. If the long sides of the blanket measure 60 inches, what is the length of the shorter sides of the blanket?

Answers

perimeter is going to be figured by using 2L + 2W

2(60) +2W = 210
120 +2W = 210
-120 -120

2W = 90
divde by 2 on both sides

W = 45

Length of the shorter sides are 45 inches.

The lengh of the shorter sides is 45 inches

AC = 4, AE = 7, AD = 10, what is the length of AB?

PLZ HELP

Answers

The above answer is not correct! The correct way to solve this is to look at the ratio of the sides as these are similar triangles. We are told that AC = 4 and AE = 7. That means that the side AC has been multiplied by 7/4 in order to become the length AE. Because these are similar trianges, all the sides must be multiplied by the same amount - therefore the side AD is equal to the length of AB multiplied by 7/4. Because we are given the side AD and need to find AB, we simply run the process in reverse like so:
If AD = 7/4 x AB:
AB = 4/7 x AD
AB = 4/7 x 10
AB = 40/7 (5.71 as a decimal)
Hope I helped :))

Answer:

The length of AB is 1 3/7 .

ilia earns $15 for each job he completes as a handyman alongside his uncle. he calculates his total job expenses for supplies to be $s. write an expression to show the amount of money ilia will have after 20 jobs.

Answers

If you are asking how much money would he have after 20 jobs while earning 15$ for each, here is the answer and explanation.

llia will have 300$ after 20 jobs. If he gets 15$ for each job then 1 is 15$, 2 is 30$, and so on. So we multiply 20 jobs x 15$ and that gives us 300$. I Hope this helps

Answers

Kilo, for kilogram is the best to use for easuring the mass of a person. 1 Kilogram (Kg) = 1000 grams. For example, I have 60 kilograms (132.27 pounds).

Mili is used for very small quantities (Mili = 1/1000 grams). Deci = 1/10 grams and deca 10 kilograms = 10.000 grams. Good luck !
