Answer:
see the explanation
Step-by-step explanation:
we know that
An extended ratio compares three or more numbers.
In the extended ratio a:b:c
The ratio of the first two numbers is a:b (you can write a to b or a/b)
The ratio of the last two numbers is b:c (you can write b to c or b/c)
The ratio of the first and last numbers are a:c (you can write a to c or a/c)
Answer:
which one ? and which one Questions
Well your equation would be 40 = 2x + 16 so subtract 16 from both sides and that’s 24=2x then divide both sides by two so the length of the rectangle is 12.
Start with a proportion, to get the number of degrees in 30 seconds:
(150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .
Cross multiply the proportion: (150 x 30) = 5 x D
4,500 = 5 x D
Divide each side by 5 : 900 = D
The globe turns 900 degrees in 30 seconds.
How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
(900 / 360) = <em>2.5 rotations</em> in 30 seconds.
