We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
I think Victoria's method is linear because the number of minutes is increased by an equal factor every month. 35+15=50+15=65+15=80
The point slope formula is y - y1 = m(x - x1)
the value x1 is the x coordinate of a point
the value y1 is the y coordinate of a point
the value m is the slope, which is 3
therefore, x1 = -2 & y1 = 1
Then, all you do is plug in the points:
y - 1 = 3(x + 2)
NOTE: It is 3(x + 2) instead of 3(x - 2) because the formula is (x - x1). If you plug x1 in, it is (x - (-2)). 2 negatives cancel out to be a positive, so it is (x + 2)
Answer : The total number of fossils at the museum are, 25
Step-by-step explanation :
As we are given that 60% of a museum’s fossils are from the Jurassic Period.
Let the total number of fossils at the museum be, 'x'
Given:
Number of fossils from the Jurassic period = 15
The % of a museum’s fossils are from the Jurassic Period = 60%
Thus, the expression will be:
By solving the term 'x' we get:
Thus, the total number of fossils at the museum are, 25
Answer:
