The size of a pancake is measured by its radius. The corner shop charges $12 for a 3-inch personal pancake. The largest pancake is a 6-inch pancake that costs $20. How many times larger is the area of the largest pancake than the personal pancake? A. 2 B. 3 C. 4 D. 6
Answer:
C. 4
Step-by-step explanation:
A pancake is circular in shape
Hence, the area of a circle = πr²
HenceThe corner shop charges
a) $12 for a 3-inch personal pancake.
For personal pancake
r = 3 inches
πr² = π × 3²
= 28.274333882 square inches
= 28.3 square inches
b) The largest pancake is a 6-inch pancake that costs $20.
For Largest pancakes
r = 6 inches
πr² = π × 6²
= 113.09733553 square inches
Approximately = 113.1 square inches
How many times larger is the area of the largest pancake than the personal pancake?
This is calculated as :
Largest pancake/Personal pancake
= 113.1/28.3
3.9964664311 inches
Approximately = 4

two years ago a man was six times as old as his daughter. In 18 years he will be twice as old as her, determine their present ages
Step-by-step explanation:
Let m = man's age right now
d = daughter's age right now
m-2 = 6(d-2) => m = 6d -12 +2 = 6d-10
m+18 = 2(d+18) => m = 2d+36-18 = 2d+18
6d-10 = 2d+18
4d = 28
d = 7
m = 32

The area of the triangle is 30 sqaure inches.
Answer:
I believe the area would be 30 inches. All you do is 12 times 5 which is 60 and then you divide 60 by two because it's a triangle, and you get 30. hope this helped.

I need help graphing -8x-y=8
Answer:
y = -8x - 8
Step-by-step explanation:
Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.
To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.
Answer:
y=8x+8
Step-by-step explanation:
Just rewrite the problem so it's in y=mx+b format then it's easy to graph
Remember the y intercept is 8 because when x=0 y=8 and the slope is 8 so go up 8 and right 1

What is the length of BD?
Answer:
[tex]10\sqrt{3}[/tex]
Step-by-step explanation:
Trigonometric Ratios
This problem will be solved by the use of a trigonometric ratio called sine because it relates the opposite side of a given angle with the hypotenuse of the triangle.
Selecting the angle of 60° in triangle ABD:
Sine Ratio
[tex]\displaystyle \sin 60^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin 60^\circ=\frac{BD}{20}[/tex]
Solving for BD:
[tex]\displaystyle BD=20\sin 60^\circ[/tex]
Since
[tex]\sin 60^\circ=\frac{\sqrt{3}}{2}[/tex]
[tex]\displaystyle BD=20\frac{\sqrt{3}}{2}[/tex]
Simplifying:
[tex]\boxed{\displaystyle BD=10\sqrt{3}}[/tex]

A. The typical value and the spread are both greater in set A.
B. The typical value is greater in set A. The spread is greater in set B.
C. The typical value is greater in set B. The spread is greater in set A.
D. The typical value and the spread are both greater in set B.
Answer:
c. the typical value is greater in set b. the spread is greater in set a
Step-by-step explanation:
The typical value is greater in set A. The spread is greater in set B.
The correct answer is an option (B)
What is the typical vale?"It is the average value (mean) of the data"
What is spread of the data?"It is the measure of how far the values in a data set are away from the mean.""The simplest measure for the spread of the data is range of the data set."What is the range of the data?"It is the difference between maximum and minimum value."
For given example,
We can observe that the typical value for set A is between 7 and 8
and the typical value for the set is in between 4 to 5.
So, the typical value is greater in set A
The range of the set A is :
R = 9 - 6
R = 3
The range of the set B:
R = 7 - 0
R = 7
So, the spread is greater in set B.
Therefore, the typical value is greater in set A. The spread is greater in set B.
The correct answer is an option (B)

Aida bought a costume box containing 50 costumes for $300. She sold all of the costumes and made a $250 profit. She sold all of the costumes for the same price. Use the equation 50c−300=250, where c is the selling price of each costume. What was the selling price of one costume in dollars?
HURRYY WILL GIVE BRAINLIEST TO THE FIRST PERSON THAT ANSWERS !!!!!
Answer:
300 + 250 = 550
550/50 = 11
$11 per costume
The selling price of each costume will be equal to $11 per costume.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

A movie theater sells popcorn and fountain drinks. Brett buys 1 popcorn bucket and 3 fountain drinks for his family, and pays $9.50. Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, and pays a total of $19.75. If p represents the number of popcorn buckets and d represents the number of drinks.
Answer:
Step-by-step explanation:
p + 3d = 9.50
3p + 4d = 19.75
-3p - 9d = -28.50
3p + 4d = 19.75
-5d = -8.25
d= $1.65 drinks
p + 3(1.65) = 9.50
p + 4.95 = 9.50
p = $4.55 popcorn

Answer:
4/3−4√5+13√7
Step-by-step explanation:
So for whatever reason we don't like it when the radical is in the denominator so we're going to do a process called rationalization and get rid of it. We do this by multiplying both the numerator and denominator by the radical
So for the first part we multiply the numerator and denominator by [tex]\sqrt{28}[/tex] which gives us [tex]\frac{42\sqrt{28} }{28}[/tex] we can then factor the 28 into sqrt(7,2,2) which simplifies to [tex]42*2\sqrt{7}[/tex]/28 So then we can simplify this and get [tex]3\sqrt{7}[/tex] We then can simplify the rest of these radicals and get [tex]2\sqrt{20}=2\sqrt{2*2*5}=4\sqrt{5}[/tex] and [tex]2\sqrt{175}= 2\sqrt{5*5*7}=2*5\sqrt{7}[/tex] This means that so far we have the following:[tex]3\sqrt{7}+ \frac{60}{45}-4\sqrt{5} +10\sqrt{7}[/tex] We can add the like terms and simplify the fraction and get 4/3−4√5+13√7
