Answer:
40 min
Step-by-step explanation:
find unit rateeee p=problems
8 p= 2 min
8/2=4
so Alison can do 4 math problems per minute
so 160/4= 40 minutes
hope this helps
720 by 600! hope this helps
Hello! I would love to help!
Okay, let's first figure out what the problem is asking us. Basically, we need to subtract 4/6 from 5/6 to find the extra left over.
Let's do it!
We need to do 5/6-4/6
To do this, subtract the numerators, or top numbers of each fraction.
The top numbers are 5 and 4
5-4=1
Now, put the new numerator over 6, the common denominator.
1/6
So, your answer is 1/6 cup extra oil.
Hope this helped! Comment if you have questions!
116 1/4 = 465/4 and 2 2/9 = 20/9
(465/4)÷(20/9) will be the answer and it is equal to 52 flags
Answer:
B
Step-by-step explanation:
The area of the square can be calculated using S^2 = x^2
The area of the circle is pi * r^2
= 22/7 * (x-1)^2
= 22(x-1)^2/7
So we need the value of x, that will make;
x^2 = 22(x-1)^2/7
In this kind of scenario, since we have options, it is best to test values instead of going through long calculations
Let’s try 2.29
So;
2.29^2 = 22/7(2.29-1)^2
5.2441 = 5.23
So close , but let’s see if any other value will
give us a closer value
Let’s work with 1.66
1.66^2 = 22/7(1.66-1)^2
2.7556 = 1.369
This is far from what we need
Let’s try 0.5
0.5^2 = 22/7(0.5-1)^2
Thus gives a negative answer on the right hand side, so no need trying
And lastly 1.25
1.25^2 = 22/7(1.25-1)^2
1.5625 = 0.1946
So the first test still gives the most probable answer to a decimal place accuracy
