Answer:
342 inches, or 28.5 feet, or 9.5 yards
Step-by-step explanation:
It is perhaps easiest to start with all the dimensions in inches.
13.5 ft = (13.5 ft)(12 in/ft) = 162 in
3.5 yd = (3.5 yd)(36 in/yd) = 126 in
Then the total of the lengths of ribbon is ...
54 in + 162 in + 126 in = 342 in
Converting to feet, we get ...
(342 in)/(12 in/ft) = 28.5 ft
And converting to yards, we get ...
(342 in)/(36 in/yd) = 9.5 yd
The total length of ribbon is 342 inches, or 28.5 feet, or 9.5 yards.
1. First, do 12 x 8 to work out the area of the rectangle, which is 96ft.
Then, to work out the area of a circle, you use the equation πr² to help you. You would multiply π by the radius², which is 16. Now you have just worked out the area of a circle, but not a semicircle, so you would have to divide your answer by two to get the area of this, which would be 25.13 (rounded to 2 d.p).
To get the area of the whole shape, you just have to add the two totals together.
25.13 + 96 = 121.13ft.
Remember to put the units there, or you can lose marks.
Try your best with the next questions! I have written the formulas for the other shapes to help you work out the answers.
Area of a square = Multiply sides together.
Area of rectangle = Multiply width by length.
Area of a circle = Multiply π by the radius².
Area of a semicircle = Multiply π by the radius², and the divide by two.
Area of a triangle = Multiply the base by the height, and then divide by two.
Really hope this helps!
Answer:
5
Step-by-step explanation:
The distance is given by sqrt((-3-0)^2+(-3-1)^2)=sqrt(9+16)=5

Answer:
Since, the given solution is (2, 14). Therefore, 7x−y=0. Similarly, another equation can be−x+y=−2+14=12. Similarly, another equation can be−2x−y=−2(2)−14=18.
