At a restaurant, the bill comes to $60. If you decide to leave a 14% tip, how much is the tip?
60 times 0.14 = 8.4
You would give $8.40 as a tip of 14% from a bill of $60
Final answer:
To calculate a 14% tip on a $60 bill, you multiply 0.14 by $60, resulting in a tip of $8.40.
Explanation:
To find out how much a 14% tip is on a $60 bill, we need to convert the percentage into a decimal by dividing by 100.
This gives us 0.14 as the decimal form of 14%.
We then multiply this decimal by the total bill amount to calculate the tip: 0.14 × $60 = $8.40
Therefore, the tip would be $8.40.
Does this graph represent a function?
A.Yes, because it passes the vertical line test
B. Yes, because its a curved line
C. No because it is not a straight line
D. No, because it fails the vertical line test
Answer:
A. Because it pass the vertical line test.
Step-by-step explanation:
Let us first understand the Vertical Line test. In this test , we draw few random vertical lines on graph and check whether any one or more than one line intersect the graph, no matter once or more. If there exists a line which intersects the graph , we say graph passes the vertical line test.
Hence this graph passes vertical line test because there are many vertical lines which intersect it.
Answer:
A.Yes, because it passes the vertical line test

How do you determine the solution of a systems of linear equations from a graph?
Question 2 options:
A.The solution is the x-intercept
B.The solution is the y-intercept
C.The solution is the intersection of both lines
D.The solution cannot be determined from a graph
Suppose you have two lines, and consider the system of their equations:
[tex] \begin{cases} y = mx+q\\y=m'x+q'\end{cases} [/tex]
Suppose that a certain point [tex] (x,y) [/tex] belongs to the first line. This means that his x and y coordinates follow the rule [tex] y=mx+q [/tex]. Similarly, if another point [tex] (x',y') [/tex] belongs to the second line, his x and y coordinates follow the rule [tex] y'=m'x'+q' [/tex].
A system is solved by the points that satisfy both equations simultaneously. But satisfying an equation means to belong to the graph that the equation represents.
So, the solution to the system is the point that belongs to both lines, i.e. that satisfies both equations.
Write the following statement as a conditional statement.
Stars have ten vertices.
A) If a figure has ten vertices, then it is a star.
B) A figure is a star, if and only if, it has ten vertices.
C) Star are figures with ten vertices.
D) If a figure is a star, then it has ten vertices.
A) If a figure has ten vertices, then it is a star. This is the correct conditional statement.
Conditional statement can be simplified as : if a, then b. Here 'a' is one condition and 'b' is second condition. So, based on this, option A is correct.
Answer:
The correct option is D.
Step-by-step explanation:
The given statement is "Stars have ten vertices".
If a complete statement has two sub statements p and q, then the conditional statement is "If p, then q", where p is a hypothesis and q is a conclusion.
In the given statement,
p = A figure is a star.
q = It has ten vertices
So, the conditional statement of the given statement is
If a figure is a star, then it has ten vertices.
Therefore the correct option is D.
4. If a = (2/5)^2 ÷(9/5)^0 , find the value of a2 ?
Answer: [tex]a^{2} = \frac{16}{625}[/tex]
Step-by-step explanation:
[tex]a = (\frac{2}{5})^{2}[/tex] ÷ [tex](\frac{9}{5})^{0}[/tex]
[tex]a = (\frac{2}{5})^{2}[/tex] ÷ 1
[tex]a = (\frac{2}{5})^{2}[/tex]
[tex](a)^{2} = ((\frac{2}{5})^{2})^{2}[/tex]
[tex]a^{2} = (\frac{2}{5})^{4}[/tex]
[tex]a^{2} = \frac{2^{4}}{5^{4}}[/tex]
[tex]a^{2} = \frac{16}{625}[/tex]

in a class of 30 students. 13 of them are boys.
what percentage of the class are girls?
give your answer to 1 decimal place.
Hello...
Students - 30
Boys - 13
Girls - ?
30 - 13 = 17
There are 17 girls!
Percentage:
17 / 30 = 0.56666666667...
= 56.6...
Answer:
56% are girls
44% are boys
56.66% is the percentage of the class are girls.
What is Percent?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is primarily used to compare and determine ratios and is represented by the symbol %.
Given:
Total students= 30
Number of boys= 13
Number of girls = 30- 13 = 17
So, percentage of the class are girls
= 17 /30 x 100
= 0.56666x 100
= 56.66%
Hence, 56.66% is the percentage of the class are girls.

Here are five number cards . 2,5,7,8,9 . One of the cards is removed and the mean average of the remaining four number cards is 6
Answer:
7
Step-by-step explanation:
Given that there are 5 number cards.
They are 2,5,7,8,9
Total of all numbers in the cards = 2+5+7+8+9= 31
One card is removed say with number x.
Now sum new would be =31-x .. i
Average of remaining 4 cards = 6
So sum of remaining 4 cards = 6(4) = 24 ... ii
i and ii represent the sum of remaining 4 cards. Hence they should be equal
31-x =24
Subtract 31 from both sides to get
-x=-7
Or x =7
Given that there are 5 number cards.
They are 2,5,7,8,9
Total of all numbers in the cards = 2+5+7+8+9= 31
One card is removed say with number x.
Now sum new would be =31-x
Average of remaining 4 cards = 6
So sum of remaining 4 cards = 6(4) = 24
represent the sum of remaining 4 cards. Hence they should be equal

Solve for x.
4x-39>-43 AND 8x+31<23
Choose 1 answer
a) x<-1 or x>-1
b) x<-1
c) x>-1
d) There are no solutions
e) All values of x are solutions
To solve the system of inequalities 4x-39>-43 and 8x+31<23, we isolate x in both equations. The solution to the system of inequalities is x>-1 or x<-1.875, but since the second inequality contradicts the first one, there are no solutions.
Explanation:To solve the inequalities 4x-39>-43 and 8x+31<23, we need to isolate x in both equations.
For the first equation, we add 39 to both sides and then divide by 4 to get x>-1.
For the second equation, we subtract 31 from both sides and then divide by 8 to get x<-1.875.
Therefore, the solution to the system of inequalities is x>-1 or x<-1.875, but since the second inequality contradicts the first one, there are no solutions.

What is 42,429 rounded to the nearest hundred
42,429 rounded to the nearest hundred is 42,400.
42,429 rounded to the nearest hundred is 42,400, as the tens digit (2) is less than 5, so we round down.
Explanation:The question is asking to round the number 42,429 to the nearest hundred. To do this, we look at the tens place, which is 2. If the tens digit is 4 or lower, we round down; if it is 5 or higher, we round up. In this case, the digit is lower than 5, so we round down. Thus, 42,429 rounded to the nearest hundred is 42,400.

A box of small crackers holds 4 equal servings. If there are 124 crackers in the box, how many crackers are in each serving?
For this equation, we can simply divide the box's total (124) by 4 servings. 124/4 = 31. So, there is 31 crackers per serving.
To find out how many crackers are in each serving, divide the total number of crackers by the number of servings.
Explanation:To find out how many crackers are in each serving, you need to divide the total number of crackers by the number of servings. In this case, there are 124 crackers in the box and 4 equal servings. So, you can divide 124 by 4 to get the number of crackers in each serving.

Answer:

Step-by-step explanation:
We are asked to
Simplify m - {n - [p + (m + n - p)]}.
For that we remove first internal bracket and then next in the same order.
= m - {n - [p + m + n - p]}. (by removing the inner bracket)
Now we simplify the term inside by cancelling p
= m - {n - [ m + n ]}. Next is multiply by - the term m+n.
= m-[n-m-n]. Now n cancels out.
=m-(m) = 0
Finally we get 0 as answer.
