What is the 10% of number in which the 14% is 160
What does percentage mean?Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has neither dimensions nor a defined unit of measurement.
being that,
14% × x = 160
14/100 × x = 160
x = 160 × 100/14
x = 1142.86
The current value is 1142.86.
10% of the total number must be located.
to say,
10% x 1142.86 = 10 / 100 x 1142.86
= 114.286
Consequently, 114.286 is the value of the 10% of the number.

A truck enters a highway driving 60 mph. A car enters the highway at the same place 8 minutes later and drives 71 mph in the same direction. From the time the car enters the highway, how long will it take the car to pass the truck?
It will take 44 minutes for the car to pass the truck.
What is relative speed ?Relative speed is the net speed difference between two objects when they are on the same direction we subtract and when they are on different direction we add.
According to the given question A truck enters a highway driving 60 mph which is (60/60) miles per minute = 1 mile per minute.
The car is going at a speed of 71 miles hour or (71/60) mile per minute = 1.183 miles per minute.
∴ Their relative speed difference is ( 1.183 - 1 ) = 0.183 miles.
Given the car enters the highway 8 minutes later on that time the truck will cover the distance of (1×8) = 8 miles.
so, the time needed for the car to pass the truck is (8/0.183) minutes which is = 43.7 minutes or 44 minutes.

Use the graph to determine the following
a. the functions domain
b. the functions range
c. the x-intercepts if any
d. the y-intercepts if any
e. the function values f(0) and f(4)
The answers are:
a) The domain is the set of all real numbers.
b) The range is R: (-∞, -2]
c) there are not any x-intercept.
d) The y-intercept is y = -5
e) f(0) = -5
f(4) = -4
How to determine the domain and range by using the graph?For a function f(x) =y, we define the domain as the set of the inputs and the range as the set of the outputs.
To identify the domain we need to look at the horizontal axis, and there we can see that the function covers it completely, then the domain is the set of all real numbers.
For the range, we look at the vertical axis. Here we can see that the function has a maximum at y = -2 and then goes down, then the range is:
R: (-∞, -2]
c) Now we want to get the xintercepts. As you can see in the graph, it never intercepts the x-axis (the horizontal one). Thus, there are not any x-intercept.
d) The y-intercept is when the graph intercepts the vertical axis, in this case the y-intercept is at y = -5
e) f(0) is the value of the y-intercept, which we already know is y = -5
for f(4) we need to find x = 4 in the horizontal axis and then find the correspondent value of the graph.
We can see that f(4) = -4.

On Saturday, some adults and some children were in a theatre.
The ratio of the number of adults to the number of children was 4:3.
Each person had a seat in the Circle or had a seat in the Stalls.
2/3 of the children had seats in the Stalls.
114 children had seats in the Circle.
There are exactly 1100 seats in the theatre.
On this Saturday, were there people on more than 70% of the seats?
You must show how you get your answer
Answer:
Yes, there were people on more than 70% of the seats.
Step-by-step explanation:
Let's start with the children. We know that 2/3 of the children had seats in the Stalls, which means that the other 1/3 of the children had seats in the Circle. We know that 114 children had seats in the Circle. Therefore, we can calculate that there were 342 children total, since 114 (1/3 of the children) times 3 is 342.
In order to find how many adults there were, we can use the ratio of adults to children, 4:3. We're basically going to undo our math from the previous part. We divide 342 by 3 to determine how much 1 is. This gives us 114, which we multiply by 4 to find how many adults there were.
There were 456 adults.
There were 342 children.
456 + 342 = 798
There were 798 people in the theatre total.
To find what 70% of 1100 is, we multiply 0.7 x 1100. This gives us 770. Because 798 is more than 770, we know that there were people on more than 70% of the seats.

David trips every two out of nine stairs he trip for the 58th time how many stairs did.
he climb
Answer:
261 stairs
Step-by-step explanation:
If David trips twice every 9 stairs and he has tripped 58 times. We can multiply 9 by 58.
58*9=522
Since David trips twice in 9 stairs, then to find how many stairs he has climbed we need to divide 522 by 2.
522/2=261
David has climbed 261 stairs.

write the equation for the line perpendicular to y=-1/4x+9 and passing through the point (-9,9) in slope-intercept form.
Answer:
y = 4x + 45
Step-by-step explanation:
The slope for the equation y = -1/4x + 9 would be the number before the x. In this case, that number is -1/4. A perpendicular slope would be the opposite inverse to this number which would be 4. We know have the slope. We need the y- intercept.
To find the y-intercept we would need and x and y value that is on the line and the slope. We are given this information. From above, we see that the slope is 4. We can use the x and y from the ordered pair given (-9,9) The x value is -9 and the y value is 9.
y = mx + b Substitute in what we know.
9 = 4(-9) + b We are soling for b
9 = -36 + b Add 36 to both sides of the equation
45 = b We now know the y-intercept
The equation will be:
y = mx + b
y = 4x + 45

{ (-2, 4), (0, 2), (-1, 3), (4, -2)}
The set of ordered pairs above
The set of ordered pairs {(-2, 4), (0, 2), (-1, 3), (4, -2)} belong to a function
[y = f(x)] considering the pairs are in the order of (x, y).
As per the question statement, we are provided with a set of ordered pairs: {(-2, 4), (0, 2), (-1, 3), (4, -2)}.
We are required to determine if the pairs in the set satisfy a function or not.
To solve this question, let us consider each pair in the form of (x, y) and then, we will have to find out a relation between x and y that will satisfy all the ordered pairs. If we are able to find out one such common relation or pattern, we will determine our ordered pairs as inputs and outputs of the same function, otherwise not.
We can say that, [tex][(-2)(-1)+2]=4,[/tex]
[tex][(0)(-1)+2]=(0+2)=2,[(-1)(-1)+3]=1+2)=3,\\[/tex]
And, [tex][4*(-1)]+2=[(-4)+2]=(-2)[/tex]
That is, all our ordered pairs {(-2, 4), (0, 2), (-1, 3), (4, -2)} satisfy the function [y = f(x) = {x(-1) + 2}], being in the order of (x, y).
Therefore, the set of ordered pairs {(-2, 4), (0, 2), (-1, 3), (4, -2)} are the inputs and outputs of the function [y = f(x) = {x(-1) + 2}].
Ordered Pairs: An Ordered Pair is a pair of elements (say a, b) having the property that [( a, b) = (p, q)] if and only if (a = p) and(b = q).
Function: In mathematics, a function is an operator, which when provided with an input, will produce a certain output.To learn more about Ordered Pairs, click on the link below.
