Answer:
49
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.Laura's design will be light enoughThe shape is given as a trapezium (see attachment).First, calculate the height (h) of the trapezium using the following Pythagoras theorem 52=h2+x2 Where: x=11−92=1 So, we have: 52=h2+x2 52=h2+1225=h2+1 Collect like terms h2=25−1 h2=24 Take square root sh=4.90The area of the shape is then calculated as follows: Area=12(11+9)×h Area=12(11+9)x4.90 Area=12×20×4.90 Area=10×4.90 Area=49
The area of the shape is 49 square inches.Hence, the shape will be light enough (because 49 is less than 80
Answer:
We need to first find the radius:
half of 12(diameter) = 6 your new radius.
Formula of a circumference:
2πr
In this case
pi is 3.14 and your radius is 6 and 2 is just 2.
2 x 3.14 x 6 = 37.68 inches.

Taking the reciprocal of a number means switching it the other way around.
The reciprocal of 5 is 1/5 .
The ratio will be 5:1
(2y + x) + (2y + x) = (-2y + x) + (2x - 15)
2y + x + 2y + x = -2y + x + 2x - 15
4y + 2x = -2y + 3x - 15
+2y + 2y
6y + 2x = 3x - 15
-2x -2x
6y = x - 15
+15 +15
15 + 6y = x
