Answer:
force of gravity is kind of force that pulls things towards the center of earth
Answer:
=
Step-by-step explanation:
The fractions are equal because we can simplify 3/6 to 1/3 as their biggest common divisor is 3
and
we can simplify 2/4 to 1/2 as their biggest common divisor is 2
So we are using the common divisor to simplify both fractions to solve this problem.
A is the answer if I calculated right ;)
Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1
So a tangent of the perpendicular line is "-(1/5)".
Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).
On the other hand, this equation pass r(1, 3), so
3 = -(1/5) times 1 + a
∴ a=16 / 5
Therefore, y=-(1/5)x+16 /5 is answer.
By the way, I'm Japanese so if you find some mistakes in my English, please let me know.
Basically you are finding the volume of a rectangular prism of 3 by 2 meters cross section and 30 meters length. Volume = (3 m)(2 m)(30 m) = 180 cubic meters.
If 60% of the water has evaporated, 40% is left. Find 40% of 180 cubic meters to answer the 2nd part of this question.
