First, we have to find the area of the wall, then the area of the window, then subtract them.
Area of wall = 9 × 9 = 81 sq.unit
Area of window = 3 × 3 = 9 sq.unit
So, the area of the wall ( excluding window ), = 81 - 9 = 72 sq. unit

A rectangular-shaped box has the following dimensions: 12 yards, 8 yards, and 18 yard. What is the surface area of the box?
Answer:
912 is the surface area
Surface area of the cuboid is the sum of the area of all the sides. The surface area of the box is 912 yards².
What is the surface area of the cuboid?The surface area of the cuboid is the sum of the area of all 6 sides of the cuboid.
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
As it is given to us that the box is rectangular, therefore, the actual shape of the box is cuboid. And for a cuboid, the surface area is given as,
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
Also, the length, breadth, and height of the cuboid is 12 yards, 8 yards, and 18 yards, therefore,
The surface area of the box = 2[(12 x 8)+(12 x 18)+(8 x 18)]
= 2[(96)+(216)+(144)]
= 912 yards²
hence, the surface area of the box is 912 yards².

A store pays $70 for a bicycle from a manufacturer. The store's markup rate is 65%.
Find the markup.
Answer:
$45.5 or the price is $115.50
Step-by-step explanation:
Write 65% as
65/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
65/100 of 70 = ? = 65/100 × 70 = ?
Therefore, the answer is 45.5

How can you isolate the variable in this inequality?
3b < -99.
A
Subtract 99 from 3b.
B
Add 99 to both sides.
C
Divide both sides by 3.
D
Multiply both sides by 3.
Answer:
C- Divide both sides by 3.
Step-by-step explanation:
In order to isolate the variable, we will have to remove all non-1 coefficients from the variable. Since 3b can be written as 3(b), b is being multiplied by 3. So the only way to isolate the variable is to do inverse operations, which would be to divide both sides of the inequality by 3.

2) 7+10+17 (count on from your fingers. call yourself ten then count 7 more)
3) quotient means to divide 44÷11 = 4 (use bus stop meathod)
4)split also means to divide 6÷2=3 (draw a line down your page and keep splitting dots between each side and stop when you get to six you should have 3 dots on eack side meaning 3 is your answer)
5) product means to times/ to multiply so 6×4=24 (use time tables)
6) sum means to add 14+4=18 (use written method used in question 1 or call yourself 14 and count on 4 steps)
7) product means to times 13× 3=39 (use written method but instead of adding times so 3×3=9 then add a zero and then do 1×3 which is 3 and then 30+9 gives you 39)

Describe the graph of the equation x = 7. Is the equation a function?
A. vertical line; no
B. horizontal line; no
C. horizontal line; yes
Answer:
no it is not, A
Step-by-step explanation:
functions are things which u can draw vertical lines through and it never intersects(one x value leads to exactly one y value) at more than one point so A because x=7 is infinite y values for one x value.

Elena plays the piano for 30 minutes each practice day.
The total number of minutes p that Elena practiced last week is a function of n, the number of practice days.
What is the domain for this function?
What is the range of this function?
Answer:
Step-by-step explanation:
f(n)=30n
domain all real numbers
range all real numbers
I think.
Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
What is a function?A relation is a function if it has only One y-value for each x-value.
The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:
p = 30n
where 30 is the number of minutes Elena practices each day.
Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:
Domain: {0, 1, 2, 3, ...}
The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.
In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:
Range: {0, 30, 60, 90, ...}
Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
