Jamie can paint a wall in 54 minutes Together Connie and Jamie can paint the same wall in 36 minutes How long would it take Connie to paint the same wall by herself
Answer:
The answer is 108
Step-by-step explanation:
I did this for my exam got 100
Together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.
We have given that,
John can paint 1/54 of a wall in 1 minute.
James can paint 1/36 of a wall in 1 minute.
What is the formula for total wall paint in one minute?Total wall paint of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute
Therefore ,total wall paint in one minute =1/54 + 1/36
So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.
1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.
Therefore,together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

The trigonometric function gives the ratio of different sides of a right-angle triangle. The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse.
What is Sine (Sinθ)?The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
The angle of elevation is equal to,
The angle of elevation = Sin⁻¹ (4.5/11.75)
= 22.5183° ≈ 23°
Hence, the angle of elevation formed by the ramp by the ground to the nearest degree is 23°.

The ratio of length to width on a rectangle is
11:3. The perimeter of the figure is 308. what is the
width of the rectangle
Answer:
[tex]Let~the~length~of~rectangle~be~'l'~and~its~width~be~'b'.\\According ~to ~question,\\l:b=11:3\\or, \frac{l}{b} =\frac{11}{3} \\or, l = \frac{11b}{3}\\Also,\\Perimeter~of~the~rectangle=308\\or, 2(l+b)=308\\or, l+b=154\\or, \frac{11 b}{3}+b =154 \\or, \frac{11b+3b}{3} =154\\or, 14b = 154(3)\\or, b=33 units\\So, ~the~width~of~rectangle~is~33units.[/tex]
Alternative method:
[tex]Let~the~length~and~width~of~the~rectangle~be~11x~and~3x.\\Given,\\Perimeter~of~the~rectangle = 308\\or, 2(11x+3x)=308\\or, 14x = 154\\or, x = 11\\Now,\\Width~of~the~rectangle,3x = 3(11)=33 units\\So,~the~width~of~the~rectangle~is~33units.[/tex]
