Answer: the correct answer to this question is option A
Step-by-step explanation:
How Do You Calculate Percentages?
To compute the percent error in any experiment or observation, the following steps must be taken:
Subtracting one value from other yields the "error" value. If you don't maintain the sign, the order is irrelevant; but, if you keep a negative sign, you get the "error" value by subtracting the accurate figure from the calculated values. The "error" value is then divided by the known or accurate value (not your measured or experimental value). This division yields a decimal number. To transform this decimal value into a percentage, multiply it by 100.
Finally, to reflect your percent error, you should place a % symbol in front of the computed figure.
Formulate the following based on the given conditions:
= [(18-8)÷8]×100
= [(10)÷8]×100
= 125 %

A restaurant customer left 1.95$ as a tip. The tax was 4% and the tip was 15% of the cost including tax.
a. Which information is not needed to compute the bill after tax and tip?
b. What was the total bill?
Answer:
To figure out the total cost of the meal, you can use the following formula:
Total cost = (Tip + Tax) / (1 - (Tip % + Tax %))
In this case, the tax is 4% and the tip is 15%, so we can plug in the values to get:
Total cost = (1.95) / (1 - (0.15 + 0.04))
Now we can solve for the total cost:
Total cost = 1.95 / (1 - 0.19) = 1.95 / 0.81 = 2.40625$
Total cost= 2.40625$So the total cost of the meal was $2.40625, including tax and the tip left by the customer.

[tex]\huge\boxed{\sf 2}[/tex]
Step-by-step explanation:
Given equation:3x + 5 = 11
Subtract 5 from both sides3x = 11 - 5
3x = 6
Divide both sides by 3x = 6/3
x = 2So, x = 2 makes 3x + 5 = 11 true.

In order to make a doughnut, a circular piece of dough that has a diameter of 2 inches is cut out of the center of a larger circular piece of dough that is 5 inches in diameter. What is the surface area of the top of the doughnut? You may leave your answers in terms of π.
Answer:
1.5π
Step-by-step explanation:
Inner circle area = π
Outer circle area = 2.5π
surface area = 2.5π-π = 1.5π
HOPE THIS HELPS!
The surface area of the top of the doughnut is 21[tex]\pi[/tex] sq inch.
How to find the area of a sector of a circle?Sector of a circle is like slice of a circular pizza. Its two straight edge's having an angle, and edge's length(the radius of the circle) are two needed factors for finding the area of that sector.
Since the whole circle with radius 'r' units have 360 degrees angle on center of the circle, and its area is
[tex]\pi r^2 \: \rm unit^2, thus, as the angle lessens, this area gets lessened. 360 degree = > \pi r^2 \: \rm unit^2 area1 degree = > \pi r^2 \: \rm unit^2/360 areax degree = > \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Thus, area of a sector with edge length 'r' units and interior angle 'x' degrees is given as:
[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Given;
The diameter of inner dough=2inches
The diameter of outer dough=5inches
To find the surface area of doughnut
=surface area of outer dough - surface area of inner dough
= [tex]\pi[/tex]R^2-[tex]\pi[/tex]r^2
=25[tex]\pi[/tex]-4[tex]\pi[/tex]
=21[tex]\pi[/tex]
Therefore, the area will be 21[tex]\pi[/tex] sq inch.

A garden consists of a rectangular sitting region surrounded by a flower border. The sitting region has a length of 3x feet and a width of 5 feet. The flower border is 3 feet wide. Write an expression, in factored form, that represents the area of the flower border. Hurry!!
Answer: 3* (36 - 5x)
Step-by-step explanation:
The total area of the flower garden is equal to the surface of the rectangle that encloses the flower's border and the sitting area minus the area of the sitting area.
Rectangle area
Three flower segments height ---- 9 feet
4 flower segments length ----------- 12 feet
Rectangle area = 12*9 ft^2 = 108 ft^2
Sitting area
Sitting area = 3x*5 = 15x
Area of the flower border (A_flwb)
A_flwb = 108 ft^2 - 15x = 3* (36 - 5x)

h ≥ 60
h ≤ 60
Thanks!
Answer: h ≥ 60
Step-by-step explanation:
≥ means more than or equal to
to be able to ride the roller coaster their height must be more than or equal to 60.
Answer: h ≥ 60
Step-by-step explanation:
h < 60 means that the height is less than 60
h > 60 means that the height is more than 60
h ≥ 60 means that the height is 60 or more
h ≤ 60 means that the height is 60 or less
So the answer would be h ≥ 60 because the height is at least 60 or more

When plotting fractions on a number line, we need to figure out how much each tick mark is. See the photo attached for how to plot 2 1/3, –5/6, and –3 1/2 on the number line.
The number lineOn a number line,
the left side shows smaller numbers, and;the right side shows greater (bigger) numbers.This number line also has negative numbers. Each tick is still worth the same on the entire number line, but leftward of 0, the numbers become negative.
How much is each tick mark?The vertical markings on the number line are called tick marks.
To get from one whole number to the next whole number on the number line, we have to count 6 tick marks. This means that each tick is 1/6.
Plot 2 1/3The dot will be between 2 and 3.

Answer:
Cubes needed to fill Prism 6: 116
The volume of Prism 6: 125
Step-by-step explanation:
First, multiply the length by the width. We can find these measurements by looking at the bottom diagonal line of the cubes.
Count how many sides are facing the front on the lowest side.
There are 5 squares facing forwards that are inside the Prism. Therefore the width/length is 5 cubic units.
Now count how many cubes it takes to go from the front side to the backside, or how many squares are facing the right. Remember this is a 3-dimensional object.
5 squares are facing the right, each belonging to the 5 cubes on the bottom of the prism.
Now count how many cubes are stacking. There are 5 cubes in the tower.
To find the volume, multiply all the measurements together.
Volume = Length x Height x Width (5 x 5 x 5)
Now to find how many cubes are needed to fill the prism, count how many cubes are already inside Prism 6.
Once you've found out how much the volume is, subtract the number of cubes inside the prism(9) from the volume(125).
125 - 9 = 116 cubes are needed to fill Prism 6.

markup,
simple interest,
percent change,
markdown,
principal
Answer:
markup is the difference between the selling price of a product and cost price. Markup = Retail – Cost.
simple interest is the interest amount for a particular principal amount of money at some rate of interest. In contrast, compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Percent change is the percent difference between a final and initial value. Find percent change by dividing the difference of values by the initial value.
A markdown is an amount by which you decrease the selling price. The amount that you decrease the price by can be expressed as a percent of the selling price, known as the markdown rate. The selling price would be determined using the equation: Percent: 1 - markdown rate.

( thank you for the help<3 )
Answer: $30 on decorations, $65 on food, $80 on party hall rental, $30 on prizes, and $45 on invitations.
Step-by-step explanation:
Hello! You are told that she has spent $375.00. You know she spent $40 on costumes, $30 on prizes, $65 on food, $45 on candy, $80 on party hall rental, $40 on music, and $45 on invitations. You can fill what you know in for food, party hall rental, prizes, and invitations. You still don't know how much Mary spent on decorations though. To find this information out. Add all of the amounts that you already know and subtract the total from 375 to find the remaining amount Mary spent for decorations. 30 + 65 + 45 + 80 + 40 + 40 + 45 = $345. Subtract 345 from 375. 375 - 345 = 30. Your final answer is she spent $30 on decorations. Hope this helps you out! :)
