Answer:
1.125 =x
Step-by-step explanation:
We can use ratios to find the time
We want to find the time needed to finish
1 - 2/5 = 3/5 We need the time for 3/5 of the project
3/4 hours x hours
---------------- = --------------
2/5 project 3/5 project
Using cross projects
3/4 * 3/5 = 2/5 * x
9/20 = 2/5x
Multiply each side by 5/2
9/20 * 5/2 = x
9/8 = x
1 1/8 =x
1.125 =x

Answer:
22.B) union
20.A) x+y=3^2
Step-by-step explanation:
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.
21. [tex]x+y=3^2[/tex] is not a function. Option A is correct.
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."
Both inequalities need to be satisfied simultaneously for the compound inequality to be true.
Hence, the compound inequality is intersection.
21. A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).
In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.
[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.
Hence, [tex]x+y=3^2[/tex] is not a function.

Please help me on this question :(
The main table is at the top. This is what it would look like if you filled out your blank boxes. The second section below shows scratch work to help form the more complicated columns.
=========================================================
Explanation:
We have two atomic variables p and q. They can each take on values of True (T) or False (F).
There are 2*2 = 4 combinations of T and F as shown below
T,T ... both trueT,F ... p is true but q is falseF,T ... p is false, but q is trueF,F ... both are falseThat takes care of the first two columns of the table. Note how there aren't any other ways to have two truth values together.
The third column ~q is where we flip everything in the q column. So if q is true, then ~q is false, and vice versa. A similar situation happens with the ~p column as well.
The ~p v q column is where we apply a disjunction to ~p with q. The V stands for "or". It means either ~p is true or q is true. If either are true, then (~p v q) is true. Otherwise it's false. Put another way, (~p v q) is only false when both ~p and q are false together.
The last column is the entire expression ~q ^ (~p v q). We apply a conjunction to the ~q column and the (~p v q) column. Both expressions must be true for the entire ~q ^ (~p v q) to be true, otherwise it's false.
Let me know if you have any questions. It's probably tricky to wrap your head around at first, but hopefully the table clears things up.
The scratch work section is to show how the fifth and sixth columns are formed.

Which fraction is equivalent to 80%?
Answer:
4/5
Step-by-step explanation:
80% is equivalent to 80/100
80/100 can be simplified into 8/10 by dividing both sides by 10
8/10 can be further simplified into 4/5 by dividing both sides by 2
4/5 can not be simplified any further

d. x= -1 and y = -1
Is it perpendicular, neither, of parallel. Show work
Perpendicular.
x = -1 is a vertical line intersecting the x-axis at (-1, 0).
y = -1 is a horizontal line intersecting the y-axis at (0, -1).
Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.

The function g(x) = 3x3 + x is an odd function. Which transformations of g(x) would result in odd functions? Check all that apply. –g(x) g(2x) g(x − 1) g(x) − 3 g(–x)
Answer:
-g(x), g(2x), g(-x)
Step-by-st-ep explanation:
if f (–x) = f (x), so all of the signs are the same
you can also try on desmos, the graph is more helpful than words explain sometimes
The functions that are odd are -g(x), g(2x), and g(-x). The correct option is A, B, and E.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
For an odd function, -f(x) = f(-x).
Given that the function, g(x) = 3x³ + x is an odd function. Therefore, the transformation of the function that will again result in an odd function is,
A.) –g(x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
B.) g(2x) ⇒ Since this will result in the same function, the only difference will be that the function will be vertically stretched.
E.) g(–x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
Hence, the functions that are odd are -g(x), g(2x), and g(-x).

Each person at a picnic chose atleast one piece of a fruit one third of the people chose an apple three -quaters of the people chose a orange what fraction of the people chose both of them
Answer:
-1/12x
Step-by-step explanation:
Let total people at the picnic=x
People who chose apple= 1/3x
People who chose orange= 3/4x
People who chose each of the fruit= People who chose apple + People who chose orange
=1/3x + 3/4x
= 4x+9x / 12
=13/12x
People who chose each of the fruit= 13/12x
what fraction of the people chose both of them?
Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit
=x - 13/12x
=12x- 13x /12
= -1/12 x

At how many values of a(0° < a < 360°) does pentagon A'B'C'DE' coincide with pentagon ABCDE? What is significant about this
number?
Answer: each time the pentagon is rotated 72, it maps back onto itself. There are five values of a for which the pentagon maps back onto itself. this is the same as the number of sides of the pentagon.
Step-by-step explanation: edmentum
A regular pentagon has 5 congruent sides and a measure of 360 degrees, at its center.
Pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)
The angle where pentagon ABCDE and pentagon A'B'C'D'E coincide is:
[tex]\mathbf{\theta = \frac{360}{5}}[/tex]
[tex]\mathbf{\theta = 72}[/tex]
Other angles between 0 and 360 degrees, where pentagon ABCDE and pentagon A'B'C'D'E coincide are multiples of 72.
So, we have:
[tex]\mathbf{a = 72^o,\ 144^o,\ 216^o,\ 288^o}[/tex]
The count of angles is 4
Hence, pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)

The number of private investigators is expected to increase from 25,000 in 2009
to 30,000 in 2019. If there are 312,500 police officers in 2009, how many police
officers must there be in 2019 to have a greater percent increase than that of
private investigators? *
Answer:
[tex]375001[/tex] police officers
Step-by-step explanation:
[tex]\frac{30,000}{25,000} = \frac{30}{25} = \frac{120}{100} = 1.2[/tex]
That's a 20% increase.
So increase the police by 20% gets you:
[tex]312500 * 1.2 = 375000[/tex]
Based on the wording of the question, if you want a greater percentage, the answer should be a single policeman more, thus 375,001.
a basketball team won 10 games and lost 15. what is the ratio of wins to the total number of games
Answer:
The total number of games =25 which is 10+15
then the number of wins are 10.
which is 10/25.
A ratio shows us the number of times a number contains another number. The ratio of wins to the total number of games is 2/5.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that a basketball team won 10 games and lost 15. Therefore, the total number of games that the team plays is,
Total number of games = games won + games lost
= 10 + 15
= 25
Now, the ratio of wins to the total number of games can be written as,
Ratio = Games Won/ Total number of games
= 10/25
= 2/5
Hence, the ratio of wins to the total number of games is 2/5.

replaced
P(white, then purple, then black)
Answer:
1 / 36
Step-by-step explanation:
There are 4 + 5 + 1 = 10 chips so there are 10 * 9 * 8 = 720 ways to choose 3 chips and not replace them. There are 4 ways to choose the white chip, 5 ways to choose the purple chip and 1 way to choose the black chip so there are 4 * 5 * 1 = 20 successful ways, therefore, the probability is 20 / 720 = 1 / 36.
