The total area of the room is 37.6376 and the no. of cans required to paint the wall is 3 cans.
The measurement of two of the walls is 2.86 metres and 3.16 metre
Area of the two walls = 2(length x breadth)
Area = 2(2.86 x 3.16) = 18.0752 m²
The measurement of the other two walls is 2.86 metres and 3.42 metres
Area of the two walls = 2(length × breadth)
Area = 2(2.86 × 3.42) = 19.5624 m²
Total area = 18.0752 + 19.5624 = 37.6376 m²
If one can of paint can cover 15 m², the no. of cans required to paint the bedroom will be
No. of cans = Total area/Area covered by one can of paint
No. of cans = 37.6376/15 = 2.5091 = 3 cans (approx.)
Answer:
3.2 gallons
Step-by-step explanation:
Write a proportion:
1 gallon / 825 square feet = x / 2640 square feet
Solve:
x = 3.2 gallons
The digit in the ten millions place of a number that is less than 55,000,000 but greater than 25,000,000 can be 3 or 4.
25,000,000 < <u>3</u>5,000,000 < 55,000,000
25,000,000 < <u>4</u>5,000,000 < 55,000,000
I think the answer is 3cm I’m not 100% sure
Question:
If cos(θ) =-8/17 and sin(θ) is negative, then sin(θ) = ___ and tan(θ) =___.
Answer:
Step-by-step explanation:
Given
cos(θ) =-8/17
Required
sin(θ) = __
tan(θ) =__
The first step is to determine the length of the third side
Given that
Where Adj and Hyp represent Adjacent and Hypotenuse
By comparison
Using Pythagoras
By Substitution
Subtract 64 from both sides
Take square roots of both sides
The question says that sin(θ) is negative; This implies that θ is in the third quadrant and as such
From trigonometry
Also from trigonometry
