dinner was 29.00 but I left a 25 percent tip, what did I end up paying?
Answer:
Your tip was $7.25 so you payed a total of $36.25 on your $29 bill.
Answer:
$36.25
Step-by-step explanation:
Multiply 29.00 by 0.25 to get 25% of 29.00. You would get 7.25. Then add the 25% tip to the dinner amount (29.00+7.25) and you would get 36.25.
The French Club ordered 19 pizzas for a party. Each pizza had 6 slices. Miguel ate 8 of the slices. How many slices were left for the rest of the club?
Answer:
106 slices left
Step-by-step explanation:
To solve this we need to multiply 19 and 6:
19 * 6 = 114
there was 114 slices of pizza
next subtract 114 and 8
114 - 8 = 106
there was 106 slices of pizza left after Miguel ate 8 slices of pizza
Final answer:
After calculating the total slices from 19 pizzas and subtracting the 8 slices consumed by Miguel, there are 106 pizza slices left for the rest of the French Club.
Explanation:
The student asked about the number of pizza slices left after Miguel ate some. To calculate this, we first need to find the total number of slices in 19 pizzas, each cut into 6 slices, and then subtract the 8 slices that Miguel ate.
Calculate the total number of slices: 19 pizzas × 6 slices/pizza = 114 slices.
Subtract the slices Miguel ate: 114 slices - 8 slices = 106 slices.
So, there are 106 pizza slices left for the rest of the French Club.

The sum of two numbers is −102. One number is 62 less than the other. Find the numbers.
The two numbers are -20 and -82. By creating two equations x + y = -102 and x = y - 62, substitute for x in the first equation and solve for y, then substitute y back into the second equation to solve for x.
Explanation:To solve the problem, you can create two equations using the given information.
The sum of the two numbers is -102, so if you call the two numbers x and y, you have: x + y = -102 . One number is 62 less than the other, so: x = y - 62.
You can now substitute the equation from step 2 into equation 1:
(y - 62) + y = -102.
Combine like terms:
2y - 62 = -102.
Then add 62 to both sides of the equation:
2y = -40.
Finally, divide both sides by 2:
y = -20.
Substitute y = -20 back into x = y - 62:
x = -20 - 62 = -82.

Henry is playing with a standard deck of cards. What is the probability that the next card he flips over is a jack or red?
Answer:
0.54
Step-by-step explanation:
In Probability "OR" means "ADDITION" and "AND" means "MULTIPLICATION"
Here, we want probability of Jack "OR" Red, so we find individual probabilities and then "ADD" them.
There are 26 cards that are RED, half of the deck. So probability of RED CARD is:
P(red) = 26/52 = 1/2
Now, there are 4 Jacks in the whole deck, 2 red Jack and 2 black Jack. We already accounted for the 2 red jacks, so we have 2 black Jacks at hand. So
P(Jack) = 2/52 = 1/26
Now, we add the 2 probabilities:
P(jack or red) = 1/2 + 1/26 = 13/26 + 1/26 = 14/26 = 0.54 (rounded to 2 decimal places)

this is just to help any of my fellow people who suck at math :)
Answer:
[tex]59.19 ft^2[/tex]
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=7.2\ ft[/tex]
[tex]\pi =3.14[/tex]
substitute
[tex]A=(3.14)(7.2)^{2}[/tex]
[tex]A=162.78\ ft^2[/tex]
step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians
[tex]\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2[/tex]
Final answer:
The area of a sector with a central angle of 8π/11 radians and a radius of 7.2 ft, using 3.14 for π, is approximately 78.60 ft² when rounded to the nearest hundredth.
Explanation:
To calculate the area of a sector of a circle, we use the formula ½ θr², where θ is the central angle in radians, and r is the radius of the circle. For a sector with a central angle of ₈π/₁₁ radians and a radius of 7.2 ft, substituting 3.14 for π, we can find the area as follows:
Use the formula: Area = (½)(θ)(r²).
Substitute the given values to get: Area = (½)(₈π/₁₁)(7.2 ft)².
Calculating using 3.14 for π we get: Area = (0.5)*(8*3.14/11)*(7.2 ft)².
Simplify and calculate the result which gives us: Area = 78.5952 ft².
Round the final answer to the nearest hundredth: Area = 78.60 ft².

Answer:
4 + x = 16
Step-by-step explanation:
In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.
Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

1. Susan decides to take a job as a transcriptionist so that she can work part-time from
home. To get started, she has to buy a computer, headphones, and some special
software. The equipment and software together cost her $1000. The company pays
her $0.004 per word, and Susan can type 90 words per minute.
a. How many hours must Susan work to break even, that is, to make enough to
cover her $1000 start-up cost?
b. If Susan works 4 hours a day, 3 days a week, how much will she earn in a
month?
Answer:
a) About 46.3 hours
b) About $1036.80
Step-by-step explanation:
a)
Break even means to make enough to cover her costs.
Given her cost is 1000, we need to find how many hours she will need to cover this up.
In 1 minute, she can type 90 words, that would pay her:
0.004 per word for 90 words = 0.004 * 90 = $0.36 per minute
Susan makes $0.36 per minute, so the amount of time (in minutes) it will take her to make $1000, is:
1000/0.36 = 2777.78 minutes
Converting that to hours, we divide by 60,
2777.78/60 = 46.3 hours
b)
4 hours per day for 3 days = 4 * 3 = 12 hours (per week)
Let there be 4 weeks in a month, so
12 hours per week * 4 = 48 hours per month
She will work 48 hours per month.
Given 90 words per minute, in 1 hour, she can type:
60 minutes * 90 = 5400 words per hour
In 48 hours, she can type:
5400 words per hour * 48 hours = 259,200 words
That would pay her:
0.004 per word for 259,200 words = 0.004 * 259,200 = $1036.80

30+2y=43
2y=43-30
2y=13
y=13/2
x+13/2=15
x=15-13/2
x=30/2-13/2=17/2
x=17/2, y=13/2.
The price of the glove is $8.5 and the price of the hat is $6.5.

Junior's brother is 5 1/2 tall. Junior is 3/5 of his brother's height. How tall is Junior?
Answer: Junior is 3 3/10 feet tall .
Step-by-step explanation:
As given
Junior's brother is 5 1/2 feet tall
i.e
Junior's brother is 11/2 feet tall
Junior is 3/5 of his brother's height
Thus
Junior's heights = 3/5 times his brother's height
Putting all the values in the formula
Junior's Height = 3/5 X 11/2
Junior's height = 33/10
Junior's height = 3 3/10 feet
Therefore Junior is 3 3/10 feet tall .
Junior's height is calculated by taking 3/5 of his brother's height, which is 5.5 feet. Multiplying these, we find out that Junior is 3.3 feet tall.
Explanation:The student is asking to solve a problem involving fractions and proportions to find out how tall Junior is compared to his brother. Junior's brother is 5 1/2 feet tall, which is equivalent to 5.5 feet. Junior is 3/5 of his brother's height. To find out Junior's height, we multiply the brother's height by 3/5:
To find Junior's height, we need to multiply his brother's height by \( \frac{3}{5} \). If Junior's brother is 5 1/2 feet tall, we can first express this height as an improper fraction:
\[ \text{Brother's height} = 5 \frac{1}{2} = \frac{11}{2} \text{ feet} \]
Now, we can find Junior's height by multiplying his brother's height by \( \frac{3}{5} \):
\[ \text{Junior's height} = \frac{3}{5} \times \frac{11}{2} \]
Multiplying the numerators and denominators:
[tex]\[ \text{Junior's height} = \frac{33}{10} \text{ feet} \][/tex]
To express this as a mixed number:
[tex]\[ \text{Junior's height} = 3 \frac{3}{10} \text{ feet} \][/tex]
Therefore, Junior is 3 feet 3 inches tall, or 3.3 feet, which is [tex]\( \frac{3}{10} \)[/tex]than 3 feet.
Height of Junior = 5.5 feet x 3/5
Height of Junior = 3.3 feet
Therefore, Junior is 3.3 feet tall.

Answer:
232 square feet
Step-by-step explanation:
The outside dimensions of the yard are 26 ft by 36 ft, so its total area is ...
yard including walk = (26 ft)(36 ft) = 936 ft²
The dimensions of the yard inside the walkway are 22 ft by 32 ft, so that area is ...
yard not including walk = (22 ft)(32 ft) = 704 ft²
The difference in these areas is the area of the walkway:
walkway area = (yard including walk) - (yard not including walk)
= (936 -704) ft² = 232 ft² . . . . area of the walk
_____
Another way to figure this is to consider the length of the centerline of the walkway. That is the perimeter of a rectangle that is 24 ft by 34 ft. The perimeter (centerline length) is 116 ft, and the width of the walk is 2 ft, so its area is ...
(116 ft)(2 ft) = 232 ft²

use the elimination method to solve the system of equations.
The asymptotes of the function f(x) = 7/(x^2 - 2x - 24) are located at x = 6 and x = -4.
Explanation:The function f(x) is a rational function, which means it's a fraction of two polynomials. The function has vertical asymptotes where the denominator (x^2 - 2x - 24) equals zero.
To find the asymptotes, set the denominator equal to zero and solve for x:
x^2 - 2x - 24 = 0
Factor the equation: (x - 6)(x + 4) = 0
Therefore, x = 6 and x = -4 are the roots of the denominator.
Since the denominator becomes zero at x = 6 and x = -4, these points represent vertical asymptotes where the function approaches positive or negative infinity.
Therefore, the function f(x) has asymptotes at x = 6 and x = -4.
I need help with Law of Sines; I posted pictures but I need help ASAPP
Answer:
B = 26.407 degrees
C = 73.593 degrees
c = 30.196 units
Step-by-step explanation:
Use the law of sines
sin(B) / 14 = sin(80) / 31
B = sin-1( sin(80) / 31 x 14)
B = 26.407
C = 180 - 80 - 26.407
C = 73.593
c / sin(73.593) = 31 / sin(80)
c = 31 / sin(80) x sin(73.593)
c = 30.196

Which statement is FALSE?
A) A trapezoid with only one pair of parallel sides does not have rotational symmetry.
B) The perpendicular bisector of the base of any trapezoid is always a line of symmetry.
C) The perpendicular bisector of the base of an isosceles trapezoid is always a line of symmetry.
D) An isosceles trapezoid with only one pair of parallel sides can have only one line of symmetry.
Answer:
B.
Step-by-step explanation:
This is only true if it is an isosceles trapezium so B is false.
Final answer:
The false statement is that the perpendicular bisector of the base of any trapezoid is always a line of symmetry. This is incorrect as only isosceles trapezoids, which have two non-parallel sides of equal length, are symmetrical in this way.
Explanation:
The statement that is FALSE is: B) The perpendicular bisector of the base of any trapezoid is always a line of symmetry. This statement is incorrect because a trapezoid, by definition, has only one pair of parallel sides, and not all trapezoids are symmetrical unless specified as an isosceles trapezoid. For instance, in irregular trapezoids where the non-parallel sides are of different lengths, the perpendicular bisector of the base does not act as a line of symmetry.
Moreover, statement C, which is true, specifies the conditions under which the perpendicular bisector of the base can be a line of symmetry - that is, in the case of an isosceles trapezoid. An isosceles trapezoid is specifically designed to be symmetrical along the perpendicular bisector of its bases, given its two non-parallel sides are equal in length, unlike general trapezoids.
