Answer: The measure of the complement of angle x=90-x=90-30=60º
Step-by-step explanation:
Answers:
- In the top row, the first and third polygons are regular polygons.
- In the bottom row, only the first polygon is a regular polygon
============================================================
Explanation:
A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.
The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.
--------------------
In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.
The third figure in the bottom row is not regular because one side is longer than the others.
Answer:
Step-by-step explanation:
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute.
Answer:
51 MPH
Step-by-step explanation:
4 days is 96 hours, all you have to do is 4717/90
which is 51.41111 (with the 1 repeating) rounded to the nearest MPH (Nearest whole number) is 51
Answer:
1. 10 weeks
Step-by-step explanation:
Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.
... $6 × w = $60
Divide by $6 to get ...
... w = $60/$6 = 10
Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

<em>Comment on the problem statement</em>
The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)
