Answer:
yes
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
Step-by-step explanation:
number of tiles needed = Area of comfort room / area of tiles
Area of a square = length²
convert area of comfort room to cm
100 cm = 1 meter
2 x 100 = 200
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
50 tiles are more than enough to tile the room

Answer:
The base of the ladder has a length of 8 ft.
Step-by-step explanation:
We have to draw a triangle, as the figure attached.
The hypothenuse of the triangle is the length of the ladder (17 ft).
The height on the wall that the ladder reach is the adjacent (15 ft).
The base of the ladder is our unknown quantity X.
We will use the Pythagorean theorem to express the relation between these numbers:
The base of the ladder has a length of 8 ft.
Answer:
⅑
Step-by-step explanation:
Let m represents number of males, and f represents number of females taking the maths course.
Given that number of males (m) taking the maths course is 8 times as much as number of females (f), total number of students taking the maths course (T).
Thus we can represent the information above with the following:
m = no. of males
f = no. of females
T = Total
m = 8f
T = m + f
Thus,
Total = 8f + f = 9f
==>The fraction of the course that are females = No. of females (f) ÷ Total no. of students (T)
= f/9f
Fraction of females in simplified form would be ⅑
The price of one more-expensive blouse) . . . . . P
The cost for three of them . . . . . . . . . . . . . . . . 3 P
The price of one less-expensive blouse . . . . . P - 3
The cost for three of them . . . . . . . . . . . . . . 3(P-3) = 3P - 9
The cost for all six blouses . . . . . 3P + (3P - 9)
That's $91.50 . 3P + (3P - 9) = $91.50
3P + 3P - 9 = $91.50
Combine like terms: 6P - 9 = $91.50
Add 9 to each side: 6P = $100.50
Divide each side by 6 : P = $16.75
Each more-expensive blouse cost $16.75 .
Each less-expensive blouse cost $13.75 .
Check: 3 ($16.75) + 3 ($13.75)
= $50.25 + $41.25
= $91.50 yay !
