Q) Without a calculator, we must estimate the value of the following expression:
![3-\sqrt[]{38}.](https://tex.z-dn.net/?f=3-%5Csqrt%5B%5D%7B38%7D.)
A) I estimate 3 - √38 to be approximately -3.2.
First, we estimate the value of √38. √38 is between √36 and √49, but close to √36 (since 38 is closer to 4 than it is to 9). Since √36 is 6, √38 is probably something like 6.1 or 6.2. Filling 6.2 in the expression and simplifying, we have this:
So, I expect the number 3 - √38 to be close to -3.2.
Using a calculator we find that: 3 - √38 ≅ -3.16, which it is approximately the result that we found.
Answer
Without a calculator we find that 3 - √38 ≅ -3.2.
If the lines are congruent it should be 2 because 4 should be double of x
The best approach to take here is to find out what 1% and 10% are, then multiply them accordingly.
To find 10%, just divide the amount of quarts by 10.
480/10= 48
Therefore, 10% is 48 quarts.
To find 1%, you then divide the 10% by 10.
48/10= 4/8
Therefore, 1% is 4.8 quarts.
As you're looking for 76, you can either multiply the 1% by 76, or you can break it down into two parts, which may be easier, which is the method that I will use.
I would split it into 70% and 6%
As you've got 10%, in order to find 70%, you just need to multiply this by 7.
48*7= 336.
you then need to find the odd 6%.
As you've find 1%, you need to then multiply this by 6.
4.8*6= 28.8
You then need to add these together to get your total.
336+28.8= 364.8
As you're looking for the remainder, you then need to take this away from 480.
480-364.8= 115.2
Therefore, you have 115.2 quarts of mustard oil remaining.
Hope this helps :)
It would be 50 percent or .5 the chances of odd would be 3/6 so 3/6*3/6 would be half of each dice. so 50% i believe
Given :
The ratio of collectable cards Deshawn owns to cards that Stephanie owns is 5:2.
Stephanie has 36 cards.
To Find :
How will the ratio of Deshawn's cards to Stephanie's cards change if they both sell half there cards.
Solution :
Number of card Deshawn had, n = 5/2 × 36
n = 90 .
Number of card after they sell half there cards :
Therefore, new ratio is 
.
So, new ratio will be same.
