Answer:
The best estimate is 27 dollars.
Step-by-step explanation:
When you divide 295 dollars by 11, you will get a very long decimal, do the first 2 numbers of the 1s place and 10s place in the decimal. After that, you have to round the 26.81. Since 8 is bigger than 5, you can round it to 27.00, and get your answer, which is 27 dollars.

Answer:
Step-by-step explanation:
We can use Hypotenuse Theorem for this:
For triangle ABC,
AC²=CB²+BA²
9²=CB²+3²
Switch the sides
-CB²=3² -9²
-CB²= 9-81
-CB²= -72
the signs cut each other
CB²=72
the square changes sides
CB=√72
CB= 8.49 cm
Now triangle CBD
We have the length of CB but not the other two whereas we have the angle
It will be sin
As we know sin= O/H
Here O is CB whereas H is CD
Put the values
sin 50= 8.49/H
H= 8.49 ÷sin 50
Calculate
H=11.1 cm
As we know H is CD so CD is 11.1 cm
Hope it helps
Density=m/V
m=80 gr
V=200cm^3
Density=80gr/200cm^3
Density=0.4 gr per cubic centimeter
75/4=25 pages per hour, so, now we have to divide 250 by 25.
250/25=10
So, it would take Joan 10 hours to read 250 pages. :)
