The earth is approximately circular in cross section, with a circumference at the equator of 24 comma 882 miles. suppose two ro
1 answer:
1. find the radius of the equator. You know that the formula for the circumference is , then
mi.
2. If you are using a rope 48 ft=0.0091 mi longer than the first rope (then the circumference is 24882.0091), then you obtain another radius:
mi.
3. The difference between radii is 3,962.103359-3,962.101910=0.001449 mi (similarly 7.65 ft)

Answer:
h = 2.5
Step by step explanation:
We have been given an equation that models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill.
To find value of u we will solve our equation.
Upon using distributive property we will get,
Now let us add 18 to both sides of our equation.
Now let us combine like terms.
Upon dividing both sides of our equation by 10.5 we will get,
Therefore, value of u is 2.5.
Answer:
From the graph attached, we know that by the corresponding angle theorem, this theorem is about all angles that derive form the intersection of one transversal line with a pair of parallels. Specifically, corresponding angles are those which are placed at the same side of the transversal, one interior to parallels, one exterior to parallels, like
and
.
We also know that, by definition of linear pair postulate, and
are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.
They are supplementary by the definition of supplementary angles. This definition states that angles which sum 180° are supplementary, and we found that and
together are 180°, because they are on a straight angle. That is,
If we substitute for
, we have
, which means that
and
are also supplementary by definition.
