Answer:
A=20,000 m2 per year
Step-by-step explanation:
we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m
V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
Answer:
x = 6
Step-by-step explanation:
Similar triangles mean that it is the same shape (with same angles) but different side lengths. To find out "x", the scale factor is needed first. The scale factor is the amount that one side length is scaled (or multiplied) to equal the corresponding side length on the other similar shape.
To find the scale factor, pick a corresponding side that both triangles have a value, such as the hypotenuse, 15 and 9.
15 / 9 = 5/3 (scale factor)
The corresponding side for x is 10.
With the scale factor, divide 10 by it and x equals 6.

Answer:
1 1/8= 9/8 or 1.125
1 7/16= 23/16 or 1.4375
1 1/2=3/2 or 1.5
1 13/8=21/8 or 2.625
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.
<em>Laura's design will be light enough</em>
The shape is given as a trapezium (see attachment).
First, calculate the height (h) of the trapezium using the following Pythagoras theorem
Where:
So, we have:
Collect like terms
Take square roots
The area of the shape is then calculated as follows:
The area of the shape is 49 square inches.
<em>Hence, the shape will be light enough (because 49 is less than 80)</em>
