Answer:
Step-by-step explanation:
2x + 3 + 4x + 2 + 2x - 1 = 180 (bc the sum of the angles of a triangle = 180)
8x = 176
x = 22
2x + 3 = 47
4x + 2 = 90
2x - 1 = 43
Answer:
each car travel in one revolution in terms of π .
270.04 feet each car travel in one revolution .
Step-by-step explanation:
Formula
Where r is the radius of the circle .
As given
A Ferris wheel has a diameter of 86 ft.
= 43 feet
Thus
Therefore each car travel in one revolution in terms of π .
Now
π = 3.14
= 270.04 feet
Therefore 270.04 feet each car travel in one revolution .
Answer:
Step-by-step explanation:
3/12=1/4, which means 1 banana per muffin
5/24=4.8, which means 5 bananas per muffin
1/48, which means 1 banana per 48 muffins
Remember the Rules of Operations (PEDMAS):

So with the expression <em>3 + 4 x 3 - 3 x 5</em> we know to multiply first. So let's multiply <em>4 x 3</em> and <em>-3 x 5</em> first:
3 + 4 x 3 - 3 x 5
= 3 + 12 - 15
Then let's work out the rest of the expression!
3 + 12 - 15
= 15 - 15
= 0
Therefore we can determine that <u>3 + 4 x 3 - 3 x 5 = 0</u>

Answer:
Step-by-step explanation:
This half life exponential decay equation goes by the formula:
Where
Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:
So,
Now
third choice is correct.
