Answer:
d = 67.5
e = 22.5
Step-by-step explanation:
d + e = 90
d = 3e
Therefore, we can simply divide 90 by 4, which gives us 22.5, and also tells us what e equals. Then, multiply that by 3 to get d.

Ruth is knitting hats to sell at a local fair. The booth costs her $63 and the materials for each hat cost $10. She plans on selling them for $19. How many hats will Ruth have to make to break even, and how much will sales and costs be at that point?
Answer: Ruth have to make 7 hats to break even.
Step-by-step explanation:
Break even point is a point where Cost = Revenue.
Let x be the number of hats sold.
Given: Cost of booth = $63
Each hat cost = $10
Selling price for each cost = $19
As per given,
Total cost = Cost of booth+ (Cost of each hat)(Number of hats)
= 63+10x
Total selling price = 19x
For break even,
63+10x=19x
9x=63
x=7
Hence, Ruth have to make 7 hats to break even.
5. You are scheduling your classes for next year. There are 4 required classes: a physical education
class, a history class, an english class, and a math class. You can choose from 5 physical education
classes, 6 history classes, 5 english classes, and 3 math classes. In how many different ways could
you select the 4 required classes?
==============================================
Explanation:
For now, let's consider we can only select 2 classes instead of 4. Let's say we only had to worry about PE and history.
Let A,B,C,D,E represent the five PE classes.
Let F,G,H,I,J,K represent the six history classes.
If you arrange the letters in a table, you should get 5*6 = 30 different inner boxes of the table. Refer to the diagram below.
Each two letter code in the table represents the 2 class combo. For example, BG means you picked PE class B and history class G.
This idea can be extend to selecting 3 classes. Imagine that each of the codes in the table are laid along the side of a new table. So we'd have a table of 30 rows. Then lay out 5 columns (say with letters L,M,N,O,P) to represent the 5 English classes. You would get a table of 30*5 = 150 different combos here. Of course you shouldn't actually make such a table since it's so large, but I'm simply just saying for you to imagine one. All of the tables mentioned are completely optional. A tree diagram is another way to organize things, though tree diagrams tend to get cumbersome.
Anyway, we would have 5*6*5 = 30*5 = 150 different ways to pick the PE, history and English classes. We can extend this out to include the math classes as well.
-------------------------
In short, all we do is multiply the given values together:
5*6*5*3 = 30*15 = 450
This idea is known as the counting principle.
If the diameter of the circle is 42 cm, then the area of the shaded area is
9514 1404 393
Answer:
781.4 cm²
Step-by-step explanation:
The shaded region consists of four (4) 30° sectors and eight (8) 60° segments. The formulas for the areas of these figures can be used.
area of sector = (1/2)r²θ
area of segment = (1/2)r²(θ -sin(θ))
For radius r, the area of the 4 sectors is ...
sector area = 4(1/2)(r²)(π/6) = (π/3)r²
and the area of the 8 segments is ...
segment area = 8(1/2)(r²)(π/3 -sin(π/3)) = 4r²(π/3 -√3/2) = (4/3)πr² -r²(2√3)
So, the total shaded area is ...
shaded area = r²(π/3 +4π/3 -2√3)
The radius of the circle is 21 cm, so the shaded area is ...
(21 cm)²(5π/3 -2√3) ≈ 781.4 cm²
An electrician earns $110 after his first hour of working for a client. His total pay based on the number of hours worked can be represented using the sequence shown.
110, 130, 150, 170, ...
Which recursive formula can be used to determine the total amount of money earned for each successive hour worked based on the amount of money currently earned?
f(n + 1) = f(n) + 20
f(n + 1) = f(n) + 110
f(n + 1) = f(n + 1) + 20
f(n + 1) = f(n + 1) + 110
Answer:my guess would be A because B and D there was already a start-up salary of 110$, but it could be c, i just wanted to choose the simplest answer choice.
Step-by-step explanation: it just makes sense that it is not B or D
The recursive formula that could be used for measuring the total amount of money is f(n+1) = f(n)+20.
What is a recursive formula?A recursive is a type of function or expression stating some concept or property of one or more variables, which is specified by a procedure that yields values or instances of that function by repeatedly applying a given relation or routine operation to known values of the function.
Given that,
The electrician earns $110.
And the sequence should be 110, 130, 150, 170, and so on.
Here we assume that f(x) represent pay.
And x be the number of hours worked.
Based on the above information, we can see that there are 20 increments in every next number.
So, the equation should be f(n+1) = f(n)+20
hence, the recursive formula that could be used for measuring the total amount of money is f(n+1) = f(n)+20.

Solve the following equation for A. Be sure to take into account whether a letter is
capitalized or not.
q2 = g(-h + A)
Answer:
A = (q² + gh) / g
Step-by-step explanation:
Given equation:
q² = g(-h + A)
Solve for A
q² = g(-h + A)
q² = -gh + gA
Add -gh to both sides
q² + gh = -gh + gA + gh
q² + gh = gA
Divide both sides by g
(q² + gh) / g = gA / g
A = (q² + gh) / g

Answer:
185.25 cm^2
Step-by-step explanation:
since only length is given i considered the wall as square shape. So given :
length = 13.5 cm
area of the wall = l^2
= 13.5^2
=182.25 cm^2
Which of the following best describes the equation below? 3(x + 9) + 6x = 9x - 27 A. no real solutions B. exactly one real solution, x = -1 C. exactly one real solution, x = D. infinite real solutions
Answer:
no solutions
Step-by-step explanation:
3(x + 9) + 6x = 9x - 27
Distribute
3x+27 +6x = 9x -27
Combine like terms
9x +27 = 9x -27
Subtract 9x from each side
27 = -27
This is never true so there are no solutions

Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK
Answer:
IK = 20
Step-by-step explanation:
If Point J is on the line segment IK, then;
IK = IJ + JK
Given that
IJ = 4
IK = 5x
JK = 4x
Substitute into the expression
5x = 4 + 4x
5x - 4x = 4
x = 4
Get the value of IK
IK = 5x
IK = 5(4)
IK = 20
Hence the numerical length of IK is 20
