So this is what you know:-
8 car race
What your looking for:-
How many arrangements for the first, second, and third place?

AfilCa [17]3 years ago

3 0

Answer:

Step-by-step explanation:

The actual answer would be 21 because 8 people can qualify for first place and after only 7 for second place because someone already got first, then for third place only 6 would qualify but, here the only reasonable answer would be 24 because maybe all 8 people can qualify for first, second, and third, which would make no sense.

In the figure, lines a, b, and c are parallel and m∠4=68° . Drag and drop the correct angle measure for each angle. m∠1 = m∠2 =

The complete question in the attached figure

we have that
m∠4=68°

we know that
m∠4 and m∠3 are supplementary angles
so
m∠3=180-m∠4----- m∠3=180-68------> m∠3=112°

m∠3 = m∠2 --------> by alternate interior angles
so
m∠2=112°

m∠1 = m∠4 --------> by alternate exterior angles
so
m∠1=68°

m∠5 = m∠4---------> by corresponding angles
so
m∠5=68°

the answers are
m∠1=68°
m∠2=112
m∠3=112°
m∠5=68°

What can I learn in finding the sum of consecutive numbers?

Helga [31]

Answer:

By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.
