Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.

Answer:
36
Step-by-step explanation:
Let the total number of cotton candy = A
Number of blue cotton candy = 27 cones
Percentage of blue cotton candy = 75%
Therefore, the total number of cotton candy is calculated as:
27/A × 100 = 75%
2700/A = 75
Cross Multiply
75A = 2700
A = 2700/75
A = 36
Therefore, the amount of total cotton candy that we have is 36.
If you take the point on the bridge directly beneath the lowest point on the cable to be the origin, then the parabola has equation
300 ft to either side of the origin, the parabola reaches a value of <em>y</em> = 90, so
Adding these together eliminates <em>b</em> and lets you solve for <em>a</em> :
Solving for <em>b</em> gives
So the parabola's equation is
150 ft away from the origin, the cable is at a height <em>y</em> of
ft above the bridge.
I) 4 7/9 ii) 4 1/4
i) 42/11 ii) 66/12
Step-by-step explanation:
Negative four
-4
Equal to x
-4=x
Divided by five
-4=x/5
Plus six
-4=x/5 +6
Interpretation in the picture above
Solution
Multiply through with 5
5×-4=5×x/5 + 5×6 as shown in the second picture
-20=x+30
Collect like terms
-20-30=x
-50=x or x=-50
