Maggies brother is 7 years younger than twice here. The sum of their ages i 32
How old is Maggie
Maggie is
Years old
Answer:
Maggie is 13years old
Step-by-step explanation:
Let the age of Maggie be = x
Let her brothers age be = y
Given:
Brother is 7 years younger than twice her age , y = 2x - 7 --------- ( 1 )
[ Twice her age = 2x
7 years younger than twice her age = 2x - 7 ]
Sum of their ages , x + y = 32 -------- ( 2 )
Substitute ( 1 ) in ( 2 ) :
x + ( 2x - 7 ) = 32
x + 2x - 7 = 32
3x = 32 + 7
3x = 39
x = 13
Maggie's age = 13 years
Substitute x in ( 1 ) :
y = 2x - 7
= 2 ( 13 ) - 7
= 26 - 7
= 19
Brother's age = 19 years

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.

find the difference between the longest and shortest bean sprouts
Please i need
Answer:
7/4 inches
Step-by-step explanation:
Longest bean sprout = 8/8 + 8/8
Longest bean sprout = 1 + 1
Longest bean sprout = 2
Shortest bean sprout = 2/8
Difference = 2 - 2/8
Difference = (16-2)/8
Difference = 14/8
Difference = 7/4
Hence the distance is 7/4 inches

Answer:
$156
Step-by-step explanation:
(9600 + 5376 )/ (8 * 12) = 156
Answer:
$156
Step-by-step explanation:
interest for 8 years = $5376
convert 8 years to months
1 year = 12 month
8 years = 8*12
=96 months
monthly
now monthly interest = $5376/96
=$56
now find amount that he has to pay monthly
=$9600/96
=$100
monthly payment with interest = $100 + $56
=$156

Emil is cutting a 72-inch-long board and a 54 in long board into shelving. He wants to make as many shelves as he can while using up all the wood. What is the longest possible length of the shelves?
Answer: The longest possible length of the shelves = 18 inches
Step-by-step explanation:
Given: Lengths of two boards are 72-inches and 54 inches.
To make as many shelves as he can while using up all the wood we will find the longest possible length of the shelves = HCF ( 72, 54)
72 = 2 x 2 x 2 x 3 x 3
54 = 2 x 3 x 3 x 3
HCF(72,54) = 2 x 3 x 3 = 18
Hence, the longest possible length of the shelves = 18 inches

Identify whether the figure has plane symmetry, symmetry about an axis, or neither. HELP NEEDED NOW!!!
Answer:
The plane figure has a symmetry about an axis
Answer:
plane symmetry and symmetry about an axis
Step-by-step explanation:
A three-dimensional figure has plane symmetry if a plane can divide the figure into two congruent reflected halves.So, the given figure has seven plane symmetries.
A three-dimensional figure has symmetry about an axis if there is a line about which the figure can be rotated by an angle greater than 0∘ and less than 360∘ so that the image coincides with the preimage.So, the given figure has symmetry about seven axes.
Therefore, the figure has plane symmetry and symmetry about an axis.

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.
