Answer:
What’s the question?
Step-by-step explanation:
<span>Since we are finding three arithmetic means between 7 and 21, that means there are 4 intervals between 7 and 21. The difference between 21 and 7 is 14, which we divide by 4 to get the value of each interval.
Since each interval is 14/4 or 3.5, we keep adding that value to 7 to get our three arithmetic means.
They are 10.5, 14, and 17.5</span>
Answer:
Acute
Step-by-step explanation:
It should be acute as its less than 90 (right angle) and that also mean its not obtuse ( any angle more than 90.
Total-$31.23
explaination- you multiply 2.25 x4.8 and get 10.80 and then you multiply 2.25x7.3 and get16.43 then u add 4 to each of them and add them all up 14.80+16.43=31.23 and the 4 dollars are already included
