Answers
Answer:
c/20 cups
Step-by-step explanation:
Number of students in the baking club = 10
If each student made 2 cakes
then total cakes prepared by the students = 10 × 2 = 20
If total amount of flour used to prepare 20 cakes = c cups
and amount of flour used to prepare one cake = n cups
Then amount of flour used to prepare 20 cakes = 20n
Therefore, total amount of flour c = 2n
or n = c/20
Amount of flour used for one cake = c/20 cups
Answer:
the answer is c/20 cups!

A helicopter flies between two islands that are 20 miles apart. The angle of elevation with one island is 15o and 35o with the second island. What is the mileage of the helicopter? Round your answer to the nearest tenth of a mile. (Law of Sines or Law of Cosines Problem)
Answers
Answer:
Step-by-step explanation:
From the figure attached,
A helicopter is flying at a height 'h' and angle of elevations from two islands C and B are 35° and 15° respectively.
Let the measure of BD = x miles
From ΔABD,
tan(15) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{h}{x}[/tex]
h = x.tan(15) ---------(1)
From ΔACD,
tan(35) = [tex]\frac{h}{12-x}[/tex]
h = (12 - x).tan(35) ------(2)
By equating the values of h from equations (1) and (2),
x.tan(15) = (12 - x).tan(35)
[tex]\frac{x}{12-x}=\frac{\text{tan}35}{\text{tan}15}[/tex]
[tex]\frac{x}{12-x}=2.613[/tex]
x = 2.613(12 - x)
x + 2.613x = 31.386
3.613x = 31.386
x = 9.914 ≈ 9.9 miles
From equation (1),
h = x.tan(15)
= 9.9[tan(15)]
= 2.65 ≈ 2.7 miles
Therefore, helicopter is flying at the vertical height = 2.7 miles and horizontal distance of the helicopter from the island B = 9.9 miles.

The Navy Pier Ferris Wheel in Chicago has a circumference that is 56% of the circumference of the first Ferris wheel built in 1893. The Circumfrence of the Navy Peir wheel is 439.6 ft. What is the radius of the first ferris wheel?
Answers
Hey there! I'm happy to help!
439.6 is 56% of the first Ferris wheel. The word is means equals, so we can set up the following equation. We will call the original wheel w.
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125 ft.
Have a wonderful day! :D
Step-by-step explanation:
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125
125ft.

Answers
Answer:
No.
Step-by-step explanation:
A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.

a roller coaster has four cars each with the same number of seats. these are 21 passengers seated in the roller coaster, but 3 seats are empty. write an equation that can be used to determine the number of seats in each car, s
what would that be as an algebraic expression?
Answers
Given:
Number of passengers seated in the roller coaster = 21
Empty seats = 3
Number of cars in roller coaster = 4 (each with the same number of seats)
To find:
An equation that can be used to determine the number of seats in each car.
Solution:
Let s be the number of seats in each car.
Total number of seats in 4 cars = 4s
Using the given information,
Total number of seats = Occupied seated + Empty seats
= 21 + 3
= 24
Now, the required equation is
[tex]4s=24[/tex]
Therefore, the required equation is [tex]4s=24[/tex].
Divide both sides by 4.
[tex]s=\dfrac{24}{4}[/tex]
[tex]s=6[/tex]
Therefore, the number of seats in each car is 6.
