Answer:
1000
Step-by-step explanation:
area of rectangle = width x length
Given:
- width of floor = 40 m
- length of floor = 50 m
⇒ area of floor = 40 x 50 = 2000 m²
Given:
- width of tile = 1 m
- length of tile = 2 m
⇒ area of tile = 1 x 2 = 2 m²
Number of tiles needed = area of floor ÷ area of one tile
= 2000 ÷ 2
= 1000
1864 is the answer for your question
Answer:
−3X−30
Step-by-step explanation:
Answer:
∠Q = 75°
Step-by-step explanation:
Start by recognizing that the triangle is isosceles (the long sides are marked as being equal-length). That means angles Q and R have the same measure.
Next, you use the fact that the sum of angles is 180° to write an equation.
∠R +∠P +∠Q = 180°
(2x +15)° +x° +(2x +15)° = 180° . . . . substitute the known values
5x +30 = 180 . . . . . . . . . . . . . . . . divide by °, collect terms
5x = 150 . . . . . . . . subtract 30
x = 30 . . . . . . . divide by 5
Then angle Q is ...
∠Q = (2x +15)° = (2×30 +15)°
∠Q = 75°
