Answer:
908 feet²
Step-by-step explanation:
To paint walls, we will be looking for surface area.
Since this is a room and we have three measurements, we can assume there will be the floor, the ceiling, and four walls. This means we will be looking for 6 sides in total.
-> See attached for a diagram I made of the sides we need
-> Keep in mind opposite pairs of walls will be the same, and the floor and ceiling will be the same.
We end up with the following sides:
11 * 12
11 * 12
11 * 14
11 * 14
12 * 14
12 * 14
We can simplify this to the following:
(2(11 * 12)) + (2(11 * 14) + (2(12 * 14) = 908 feet²
908 feet² must be covered with paint.
Answer
952.49feet
Step-by-step explanation:
This set up will be a right angled triangle
Height = opposite side = 425foot
Length of wire = hypotenuse= x
Angle of elevation= 26.5°
Using the SOH identity
Sin 26.5 = opp/hyp
Sin26.5 = 425/x
x = 425/sin26.5
x =425/0.4462
x = 952.49feet
Hence the length of the wire is 952.49feet
Sum of angles in a triangle = 180°, then:
∠H + ∠F + ∠G = 180°
(x°) + (x-5)° + (3x+25)° = 180°
Remove all parenthesis and computr
x+x-5+3x+25 = 180
5x + 20 = 180
5x=160
x = 32°, then ∠G = 3x+25 = 3(32)+25 = 121°
Answer:
c = 38b
Step-by-step explanation:
b = number of boxes
c = total number of cookies.
It is given to you that there are 38 cookies per box. The given equation means that The total number of cookies can be found by multiplying the amount of cookies per box with the amount of boxes in all.
c = 38b is your answer.
