3/4 left or 0.75% left because there is 100%/4 = 0.25
Answer:
58cm squared
Step-by-step explanation:
Ok so what we first want to do is find out the total area of that rectangle.
The way we do this is by multiplying the width x height which in this case is 10 cm and 7 cm.
This gives us 70 cm as the total area of the rectangle if the circular hole wasn't there. Now we need to find the area of the circle.
The way we do this is by taking the circle and finding the radius. The radius is shown as 2cm.
Now the formula to find the area of a circle is 
which means it is about 3.14 multiplied by r squared.
R squared in this problem is going to be 2 x 2 which is 4.
Now we just do 3.14 times 4 which gives us about 12.
What we do next is subtract 12 from the total area of the rectangle which is 70.
This gives us 58cm squared as an answer.
Hope this helped ! !

Answer:
Step-by-step explanation:
One approach to this type of word problem is to list the information you are given:
Step 1:
$19.95 = basic monthly charge
$0.05 = per minute charge$23.74 = total monthly billx = the number of minutes used
Step 2:
Next, put these things into an algebraic expression.
Total monthly bill = basic monthly charge + (per minute charge) * (number of minutes used)
Step 3:
Now, plug in the numbers for your first step and solve.
$23.74 = $19.95 + $0.05x
-19.95 -19.95
$3.79 = $0.05x
divide each side by 0.05 to find x
You could also rewrite the problem at step 2. It just depends if you like working with numbers (algebra, variables, etc.) or thinking about the problem in words (more a verbal style of learning).
Number of minutes used = cost for minutes / per minute charge
Number of minutes used = (Total monthly charge - basic monthly charge) / per minute charge
The answer would be 10.
You would divide 2 divided by 1/5.
The answer is palleragram sorry i do not know how to spell very well
