Answer:
Part of incomplete work = 2/3 of project
Step-by-step explanation:
Given:
Part of work completed = 1/3 of project
Find:
Part of incomplete work
Computation:
Part of incomplete work = 1 - Part of work completed
Part of incomplete work = 1 - 1/3
Part of incomplete work = 2/3 of project

how maby solutions does this have
8 + 2 (x - 6 ) = -2 +2x - 2
Answer:
This has infinite solutions.
Step-by-step explanation:
Key skills needed are: One variable equations, Algebra, Adding/Subtracting Like Terms
1) We first start with the equation: 8 + 2 (x - 6 ) = -2 +2x - 2
2) We first need to use distribution property for the parentheses.
We need to distribute the 2 to the x and the -6.
3) This would be 8 + 2x - 12 = -2 +2x - 2
4) The next thing to do is combine like terms.
Like terms are terms with the same variable, or no variable at all. 8 and 6 would be like terms, and 2x and 4x would be like terms. 2x^2 and 4x would not be like terms as one has x^2 and the other has only x.
3) Now you know what like terms are, you can implement this into the problem --> Combine the 8 and 12 on the left side + Combine the -2 and -2 on the right side ----> 2x-4 = 2x-4
4) Since both sides have the same exact thing (both sides have 2x-4) this equation has infinite solutions.
Hope you understood and have a nice day!! :D
Which statement describes a unit rate? Group of answer choices Sara is reading 97 words in 1 minute. Sara ate 3 crackers and 1 apple. Sara ate 1 cookie. Sara is driving 16 miles.
Answer:
97 words in 1 minute
Step-by-step explanation:
A unit measure is so many somethings done usually per unit time. Examples
1 orange in 1 minute.10 tomatoes per tomato plant50 miles in one hour10 cookies per week3 crackers and 1 apple is not. For ever apple, she ate 3 crackers would be
1 cookie is not. It is not per anything.
Driving 16 miles is not. Again, it is not per anything.
The answer is 97 words in 1 minute.

Kayla gets paid $15 to rake the lawn. Kayla gets paid 3 times as
much to rake the lawn as she does to mow the lawn. How much
does Kayla get paid to mow the lawn?
Answer:
$5
Step-by-step explanation:
The opposite of multiplication is division.
$15/Raking = 3 times more pay than mowing the lawn.
Divide $15/Raking by 3 and you'll get the pay for mowing the lawn.
15/3 = 5
Answer:
5
Step-by-step explanation:
2) 50 apples cost $25. How much would 75 apples cost?
Answer:
50 : 25 = 75 : 37.50
Step-by-step explanation:
If 50 apples cost $25, that means 2 apples cost $1.
75 apples cost 37.5, or $37.50

Can someone please show me the working out because I really don’t know how to find the area of this.
Step-by-step explanation:
Base of smaller pink triangle
= (3m + 6m) - 7m = 2m.
Area of smaller pink triangle
= 0.5(2m)(5m) = 5m².
Area of bigger pink triangle
= 0.5(6m)(5m) = 15m².
Hence total area shaded = 5m² + 15m² = 20m².

1.30+1.44=2.74
Harper knows he is 50 yards from school. The map on his phone shows that the school is 3/4 inch from his current location. How far is Harper from home, if the map shows the distance as 3 inches? Enter your answer in the box.
Answer:
Harper is 200 yards away from her home if the map shows 3 inches
Step-by-step explanation:
50 yards = 3/4 inch
3 inches = 3/1
3/1 x 4/4 = 12/4
12/4 = 3 inches
50 x 4 = 200

A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. Let yyy represent the ice sheet's thickness (in meters) after xxx weeks. Complete the equation for the relationship between the thickness and number of weeks.
A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25 meters thick. Let y represent the ice sheet's thickness ( in meters) after x weeks. Complete the equation for the relationship between the thickness and number of weeks.
Answer:
y = 2 - 0.25x
Step-by-step explanation:
From the question, the initial thickness of the ice sheet = 2 meters,
After 3 weeks, the thickness of ice sheet reduced to 1.25 meters
Hence, the difference in the thickness in 3 weeks is calculated as:
2m - 1.25m = 0.75m
The amount of changes that occurred in 3 weeks is given as:
= 0.75/3 = 0.25 meters,
We are told that, the ice is melting with the constant rate.
Therefore, the equation for the relationship between the thickness and number of weeks is given as:
y = 2 - 0.25x

In pedros town 42% of the houses have both internet service and a home phone. If 82% of all the houses in his town have internet service, what is the probability that a house has a home phone if it has internet service?
Answer: 0.51
Step-by-step explanation:
We know that:
For a random selection, we have a probability of 0.42 where the house has both services and a probability of 0.82 that the house has only internet service.
Let's suppose that the percentage of houses the houses with internet service (the 82% of the total) that also have a home phone is X
Then we must have that, (X/100%) times the 0.82, must be equal to 0.42
(X/100%)*0.82 = 0.42
X = (0.42/0.82)*100% = 51%
This means that 51% of the houses with internet service, also have a home phone.
Then the probability that a house has a home phone given that it has internet service, is equal to:
51%/100% = 0.51
The probability is 0.51

How does the graph of the function f(x) = 2x4− 3 differ from the graph of its parent function? Select all the transformations.
◻A.The graphs are the same.
◻B.Subtracting 3 translates the graph down 3 units.
◻C.The leading coefficient, 2, stretches the graph vertically.
◻D.Subtracting 3 translates the graph up 3 units.
◻E.Subtracting 3 translates the graph right 3 units.
Answer:
B and C are the correct options
Step-by-step explanation:
The parent function here will be ;
f(x) = x^4
Multiplying x^4 by 2 means that we are having a vertical stretching
What this means is that the leading coefficient 2 stretches the graph vertically by 2 units
Subtracting -3 means that we are translating the graph down by a value of 3 units
So the correct options are;
B and C
What is the solution to the inequality x + 4 + 2x ≤ 20 + 5x – 32
Answer:
x+4+2x = 20+5x-32
Step-by-step explanation:
x+4+2x
= 3x + 4
20+5x-32
= 20-32+5x
= 5x-12
Finding the value of X
3x+4 = 5x-12
= 4+12 = 5x-3x
= 16 = 2x
= 16/2 = X
= 8 = X
By putting the value of X in the equation
(3×8)+4
= 24 +4
= 28
(5×8)-12
= 40-12
28
28 = 28
so the X+4+2x < 20+5x-32 is wrong
HURRY! A student works at a bicycle shop. When he sells a bicycle, he earns 6% of the sale price as a commission. If he sells 1 bicycle for $450 and 2 bicycles for $250 each, what is the total amount of commission he earns?
A $69.00
B $57.00
C $6.90
D $5.70
Answer:
B.
Step-by-step explanation:
First your going to need to find 6% of 450 which is 27
then you need to find 6% of 250 which is 15 and you have two 250's so you have two 15's
next add them all up and you got yourself 57
btw sorry my explanation sucks
Answer:
57$
Step-by-step explanation:
450 + 500 = 950 and 6% of 950 is 57

Write the number 5267 correct to
the nearest hundred.
Answer:
5300.
If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.

find the total to the nearest cent $24 lunch 15% tip# show work
Answer:
$27.60
Step-by-step explanation:
First, we need to find how much the tip is:
we can convert 15% directly to a decimal:
15% = 0.15
Then we find :
15% of 24 = 0.15 x 24 = 3.59999999999999
3.599999999999999 to the nearest cent is 3.60
Then we add the tip to the original bill:
3.60 + 24 = 27.60
So the total cost of the lunch is $27.60

Answer: 30 + 10.50h
Step-by-step explanation:
From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.
The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:
= $30 + $10.50h
where h represents the number of hours for tutoring used.
For example, if 2 hours if tutoring was used, the total amount earned would be:
= 30 + 10.50h
= 30 + 10.50(2)
= 30 + 21
= $51
