Four friends go to dinner. Each chooses a different meal. When the check comes, they decide they will each pay the same amount. If the costs of the meals (including tax and tip) were $12.20, $11.00, $8.50, and $7.50, what should each friend pay so they cover the whole bill?
Answer: Each friend should pay $9.80
Step-by-step explanation: First add up all their checks, then divide them by 4 (4 because there 4 friends) to get the amount each friend needs to pay.
$12.20 + $11.00 + $8.50 + $7.50= $39.20
39.30 / 4 = $9.80
Let C be the first quadrant portion of the circle of radius 3 centered on the origin. Find the line itegral for x^2+y^2 over C.
How do I find the volume of this pyramid
Answer:
10*10*12 = 120 ÷ 3 = 40
Step-by-step explanation:
The formula to find a pyramid's volume is
V = [tex]\frac{l*w*h}{3}[/tex] (length 'times' width 'times' height, divided by 3)
8 (3x-6) = 6(4x + 8)
Answer:
There is no solution to make it true.
Step-by-step explanation:
how can you find the area of a circle? give me a good explanation please, ty!
Answer:
The area of a circle is pi times the radius squared (Area = pi radius²).
Step-by-step explanation:
The circumference of a circle is the linear distance of a circle's edge. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.
The following equation describes the relation between the circumference and the radius R of a circle:
C = 2πR
Where π is a constant approximately equal to 3.14159265..
How to find the circumference of a circle
Determine the radius of a circle. Let's assume it's equal to 14 cm.
Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.
You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².
Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.
Use our circumference calculator to find the radius when you only have the circumference or area of a circle.
Answer:
Use this formula: A = π r²
Step-by-step explanation:
A = π r²
What does A = π r² mean? :
(Area = Pi x Radius²)
π = Pi (3.14)
² = squared

Answer:
[tex]5\frac{5}{6}[/tex]
Step-by-step explanation:
The problem above requires the use of mathematical operation with mixed fractions. In order to do this, you have to convert the mixed fractions into improper fractions first.
Let's convert.
[tex]3\frac{1}{2}[/tex] = [tex]\frac{7}{2}[/tex][tex]1\frac{2}{3}[/tex] = [tex]\frac{5}{3}[/tex]Next, you have to multiply the fractions by multiplying the numerators with each other and the denominators with each other.
Let's solve.
[tex]\frac{7}{2}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{35}{6}[/tex]Since [tex]\frac{35}{6}[/tex] is an improper fraction and the choices above are mixed fractions, you have to convert it.
Let's convert.
[tex]\frac{35}{6}[/tex] = [tex]5\frac{5}{6}[/tex]Therefore, the answer is [tex]5\frac{5}{6}[/tex]
1. A recipe for 6servings of Lasagna uses 16 ounces of Italian Sausage.

Answer:
a
Step-by-step explanation:
Decide whether a discrete or continuous random variable is the best model for each of the following variables:
a. The time for a computer algorithm to assign an image to a category.
b. The number of bytes used to store a file in a computer.
c. The ozone concentration in micrograms per cubic meter.
d. The ejection fraction (volumetric fraction of blood pumped from a heart ventricle with each beat).
e. The fluid flow rate in liters per minute.
Answer:
a) Continuous
b) Discrete
c) Continuous
d) Continuous
e) Continuous
Step-by-step explanation:
Discrete variable:
Countable amounts(0, 1, 2, 3,...)
Continuous variables:
Can be decimal values.
a. The time for a computer algorithm to assign an image to a category.
Time can have decimal values, so continuous
b. The number of bytes used to store a file in a computer.
The number of bytes is never decimal, so discrete
c. The ozone concentration in micrograms per cubic meter.
Can be decimal value, so continuous
d. The ejection fraction (volumetric fraction of blood pumped from a heart ventricle with each beat).
Can be decimal value, so continuous
e. The fluid flow rate in liters per minute.
Can be decimal value, so continuous

Can someone help me with these 2 questions please???
Answer:
See step-by-step explanation.
Step-by-step explanation:
For the first question, you simply put an EMPTY circle above 2 and draw an arrow from it all the way down to -3. The reason why we put an empty circle is because there is no equal sign below it.
For the second question, you put a FILLED circle above 4 and draw an arrow from it all the way down to -3. The reason why we use a filled circle is because x is less than OR equal to 4.

hayden and jamie completed 20 math problems together, jamie completed 2 more than twice the number that hayden completed. Let p represent the number of math problems hayden completed. Write an equation that can be used to find the number of math problems that jamie completed.
Answer:
2p+2+p = 20
Step-by-step explanation:
Let p represent the number of Math problems Hayden completed.
Let 2p+2 represent the number of Math problems Jamie completed.
Next, we have to add them together so that the total Math problems they completed will be equal to 20.
Let's solve.
2p+2+p = 203p+2 = 203p = 20-23p = 18p = [tex]\frac{18}{3}[/tex]p = 6Therefore, Hayden completed 6 Math problems.
Next, we have to get how many problems Jamie completed.
Let's solve.
2p+2 = ?2(6)+2 = ?12+2 = ?14Therefore, Jamie completed 14 Math problems.
Let's check.
2p+2+p = 2014+6 = 2020 = 20It's correct!

Answer:
398,765 books were sold
Step-by-step explanation:
How to get the answer:
1) Identify the given
32,300 is percentage
8.1 % is rate
base (b) is missing
2) Solve
b= p/r
b= 32,300 / 8.1% or 0.081
b= 398,765
3) Check
398,765 x 8.1% = 32,299.97 or 32,300
