Answer:
90 km/h
Step-by-step explanation:
To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.
<em>p = 21</em>
Step-by-step explanation:
When you have a midsegment, the base is going to be two times as large as the midsegment. You can find the midsegment if you multiply it by two and set it equal to the base. I have attached a photo below that may help you.
This is the equation we will be using.

Now let's solve! Let's start by distributing the 2 by what's in the parentheses.

Subtract p from both sides.

Add 26 to both sides.
<u>p = 21</u>
-5/3, -0.1, 0.7, sqrt2, sqrt5
