To find the area of the dining room, take 20m x 20m=400m
The area of each tile is 20cm x 20cm=40cm.
Convert the are of the dining room to cm which is 400 x 100= 40000cm
The divide the area of the dining room by the are of the tiles to find how m,any tiles are needed.
Which is 40000cm/40cm= 1000 tiles
Answer:
Step-by-step explanation:
hey watch it fatty
We know that the diameter of the wheel is 80cm. Thus we can find the circumference of the wheel by the equation C=2(pi)r or, knowing that the Diameter is 2r, C=D(pi).
Now, we know that the circumference of the wheel is 80(pi)cm.
If the wheel rotates 170 times, that means we multiply the circumference of the wheel by 170 to receive the answer.
80 x 170 x pi = about 42725.66cm
we then can divide our answer by 100 to convert to meters -->
(42725.66cm)(1m/100cm) = 427.2566 which we round to 427m
Hope this helped!

90 - 33 = 57
m<P = 180 - 57
m<P = 123
answer is <span>B. 123°

m<P = 90 - 30
m<P = 60
answer is
<span>C. 60°</span>
The third choice does not represent a proportional relationship because the y-intercept ≠ 0.
Hope that helped you.
