Jamie went to dinner. Her meal cost $12.40. She wanted to leave a 15%
tip. How much was her tip?
Answer:
Hi there! The answer is $1.86. Hope this helps! c:
Step-by-step explanation:
First, convert 15% to a decimal.
15% / 100 = 0.15
Then, multiply.
0.15 * 12.40 = $1.86
Since 15% of 12.40 is $1.86, then Jamie left a $1.86 tip.

What is the slope of the equation 2x - 5y = 20?
Answer:
Dividing two negative values results in a positive value. Reorder −4 - 4 and 2x5 2 x 5 . Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 25 .
Write the equation of the graph shown below in factored form.
(the graph starts at the bottom left and continues up through the x axis at negative two to a maximum around y equals eight and goes back down through the x axis at one to a minimum around y equals negative four and back up through the x axis at three)
f(x) = (x + 2)(x − 1)(x − 3)
f(x) = (x − 2)(x + 1)(x + 3)
f(x) = (x + 2)(x + 1)(x + 3)
f(x) = (x − 2)(x − 1)(x − 3)
Answer:
f(x) = (x+2)(x-1)(x-3)
Step-by-step explanation:
f(-2) = 0, f(1) = 0, f(3) = 0. Therefore, (x+2), (x-1) and (x+3) are the factors
how can you tell that the inequality 3x - 1 > 3x +2 has no solution just by looking at the terms in the inequality
Answer:
same variable term on both sides
Step-by-step explanation:
Given
3x - 1 > 3x + 2 ( add 1 to both sides )
3x > 3x + 3 ( subtract 3x from both sides )
0 > - 3 ← not true, thus no solution
Because the variable term was the same on both sides then it is eliminated

Somebody Please solve this question without using L Hospital rule.
Evaluate if:
Answer:
1/2
Step-by-step explanation:
Given that,
[tex]\lim_{n \to 1} (\dfrac{1+\cos\pi x}{\tan^2\pi x})[/tex]
Using L Hospital's rule to find it :
[tex]\lim_{n \to a} \dfrac{f(x)}{g(x)}= \lim_{n \to a} \dfrac{f'(x)}{g'(x)}[/tex]
We have,
a = 1, [tex]f(x)=1+\cos\pi x, \ \ g(x)=\tan^2\pi x[/tex]
[tex]f'(x)=\dfrac{d}{dx}(1+\cos\pi x)\\\\=-\pi \sin \pi x\ .....(1)[/tex]
[tex]g'(x)=\dfrac{d}{dx}(\tan^2\pi x)\\\\=2\tan\pi x\times \sec^2\pi x\times \pi\ .....(2)[/tex]
From equation (1) and (2) :
[tex]\lim_{n \to 1} \dfrac{f(x)}{g(x)}= \lim_{n \to 1} \dfrac{-\pi \sin\pi x}{2\tan \pi x\times \sec^2\pi x \times \pi}\\\\\lim_{n \to 1} \dfrac{-\pi \sin\pi x}{2\tan \pi x\times \sec^2\pi x \times \pi}\\\\=\lim_{n \to 1} \dfrac{-1}{2}\times\cos^3\pi x\\\\=\dfrac{-1}{2}\times \cos^3\pi \\\\=\dfrac{1}{2}[/tex]
So, the value of the given function is 1/2.

a student earns $11.75 per hour for gardening. if she worked 21 hours this month, then how much did she earn?
Answer:
$246.75
Step-by-step explanation:
11.75 x 21 = 246.75
hope this helps <3
Answer:
If the student worked 21 hours this month, she will earn $246.75.
Step-by-step explanation:
Let [tex]x[/tex] equal hours.
If the student earns $11.75 per hour, we can represent this with the expression:
[tex]11.75x[/tex]
If she worked 21 hours this month, then:
[tex]x=21[/tex]
With that information, we can substitute [tex]21[/tex] for [tex]x[/tex] in the initial expression:
[tex]11.75(21)[/tex]
Multiply:
[tex]246.75[/tex]
Therefore, if the student worked 21 hours this month, she will earn $246.75.
-
We can check our work by setting the initial expression equal to our solution:
[tex]11.75x=246.75[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11.75[/tex]:
[tex]x=21[/tex]
Since this quotient matches the number of hours she worked, our solution is correct!
Scouting Troops in Morgan Country are putting on a crab feed to raise money for camp. They offer a complete crab dinner as well as a vegetraian option. One Troop member sold tickets for 12 crab meals and 23 vegetarian meals, with total receipts of $916. Another sold tickets for 12 crab meals and 12 vegetarian meals, bringing in a total of $696. How Much do the 2 types of tickets costs?
Answer:
cost of crab meals = $20
cost of vegetarian meals = $38
Step-by-step explanation:
Let
x = cost of crab meals
y = cost of vegetarian meals
Troop A
12 crab meals and 23 vegetarian meals, with total receipts of $916.
12x + 23y = 916
Troop B
12 crab meals and 12 vegetarian meals, bringing in a total of $696
12x + 12y = 696
12x + 23y = 916 (1)
12x + 12y = 696 (2)
Subtract (2) from (1)
23y - 12y = 916 - 696
11y = 220
y = 220/11
= 20
y = 20
Substitute y = 20 into (1)
12x + 23y = 916
12x + 23(20) = 916
12x + 460 = 916
12x = 916 - 460
12x = 456
x = 456/12
= 38
x = 38
cost of crab meals = $20
cost of vegetarian meals = $38

Your principal amount is $450 your interest rate is 6% and your time is 8 years what is your interest earned after eight years what is your new total amount earned after 8 years
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal= $450
Number of periods= 8 years
Interest rate= 6%
We will determine the interest earned and future value using simple interest and compound interest:
Simple interest:
I= P*r*t
I= 450*0.06*8= $216
Total Future Value= I + P
Total Future Value= 216 + 450= $666
Compound interest:
I= [P*(1+r)^t] - P
I= [450*(1.06^8)] - 450= $267.23
Total Future Value= P*(1+r)^t
Total Future Value= 450*1.06^8
Total Future Value= $717.23

Which statement for all trapezoids are true? Exactly one pair of opposite sides are parallel Diagonals are always congruent Opposite sides are always congruent
Answer:
Exactly one pair of opposite sides are parallel
Step-by-step explanation:
A trapezoid is a plane shape quadrilateral that has exactly one pair of its sides parallel.
The parallel sides must occur for it to be a trapezoid. If they do not, it is most likely another shape. They could occur between the top and bottom sides while the left and right sides remain non-parallel, or vice-versa.
The other options given do not fall into the description of a trapezoid, as its opposite sides and diagonals are not always congruent.

Type the correct answer in each box. Use numerals instead of words. This table represents function f. x -3 2 3 7 y -2 8 10 18 Complete this table to represent the inverse of function f. x -2 8 10 18 y Reset
Answer:
Step-by-step explanation:
Table representing the function 'f' is,
x -3 2 3 7
y -2 8 10 18
In this table for every input value of x, there is a different output value.
So the function is one to one function.
Therefore, inverse of the given function will have the table as,
x -2 8 10 18
y -3 2 3 7

The graph of a non-invertible function passes through the points (−2,4), (0,2), and (3,−2).
How is the inverse of this function graphed?
9514 1404 393
Answer:
line y = x(4, -2), (2, 0), (-2, 3)Step-by-step explanation:
The graph of an inverse relation is the reflection of the graph of the relation over the line y = x. That interchanges the coordinates of the points of the function. (-2, 4) becomes (4, -2) when so reflected, for example.

What is an EQUATION?Equations are mathematical statements with two algebraic expressions surrounding the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions written on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign. It will be regarded as a phrase.Let's use the quantity "X" as the variable in our inquiry. The number is - since 21 is less than 11 times "X," which results in seven times a number that has been decreased by 29.
11 * X-21= 7*X-2911X-21=7X-294X=-8Divide both sides of the equation by the coefficient of variableX= -2Hence we can say that after forming the equation according to the question the answer is, X=-2.

Jorge bought x tickets to attend a football game and a baseball game. The expression 8x + 62 represents the total cost of the football game, and 9x + 34 represents the total cost of the baseball game. How much more did the football game cost if Jorge bought 7 tickets for each game.
Answer:
21
Step-by-step explanation:
Let x be the amount of ticket for each game
Given
The expression 8x + 62 represents the total cost of the football game
The total coat for the.game will be
8(7)+62
= 56+62
= 118
If 9x + 34 represents the total cost of the baseball game. The total coat will be;
9(7)+34
= 63+34
=97
To know how much more football game costs, we will take the difference in their cost.
Difference = 118-97
Difference= 21
Hence football game costs 21 more than baseball
