Step-by-step explanation:
Operations With Fractions
Simplify the following operations:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)[/tex]
Convert the mixed fractions to improper fractions:
[tex]\displaystyle 5\frac{1}{4}= 5+\frac{1}{4}=\frac{21}{4}[/tex]
[tex]\displaystyle 7\frac{1}{2}=7+\frac{1}{2}=\frac{15}{2}[/tex]
Substituting:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}-\left(-\frac{15}{2}\right)[/tex]
Simplifying:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{15}{2}[/tex]
Amplifying the second fraction by 2:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{30}{4}[/tex]
Adding both fractions:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=\frac{9}{4}=2\frac{1}{4}[/tex]

A ride-sharing company claims that the cost of rides follows a Normal distribution with a mean of $10.52. After
paying for a ride from this company, a rider reports that his price is in the 85th percentile of all other riders' prices. If
this rider paid $15.93, what is the approximate standard deviation of this company's ride-sharing cost?
Answers
Answer:
$5.20
Step-by-step explanation:
According to the Z-Score chart, the 85th percentile has a z-score of 1.04 and if you put that in the z-score equation (15.93-10.52)/x=1.04. Solve for x and you get $5.20.
Please help me asap help. The other two options are 6 2/8 and 6 1/4
Answers
Answer:
6 1/2
Step-by-step explanation:
To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

What is the value of the expression when b = 2 and c = –3? Enter your answer in the box.
Answers
Answer:
The answer to your question thinking that you're multiplying is -6
Step-by-step explanation:
The value of the expression b²+ c², when b = 2 and c = –3, is 13.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
We have an expression,
b²+ c².
The value of the expression when b = 2 and c = –3,
= (2)²+ (-3)²
= 4 + 9
= 13
Therefore, the value is 13.

Each day a machine makes 500000 staples and puts them into boxes.
The machine needs 165 staples to fill a box.
How many boxes will be filled with the 500,000 staples?
Answers
Answer:3031 boxes will be filled with staples
Step-by-step explanation:
Given that the machine makes 500000 in a day
So total staples = 500000
Staples in a box = 165
In order to find how many boxes the machine will make, the total number of staples has to be divided by the number of staples in a box.
So,
[tex]number\ of\ boxes = \frac{Total\ staples}{Staples\ in\ a\ box}\\= \frac{500000}{165}\\= 3030.30[/tex]
As no staples can be left out of box, we will round off the number to next number.
So,
3031 boxes will be filled with staples
Answer:
3031 boxes

Step-by-step explanation:
Answer:
The answer is h=15
Step-by-step explanation:
3.5 h+4.5)= 57
Let's solve your equation step-by-step.
3.5h+4.5=57
Step 1: Subtract 4.5 from both sides.
3.5h+4.5−4.5=57−4.5
3.5h=52.5
Step 2: Divide both sides by 3.5.
3.5h/3.5=52.5/3.5
h=15

Sarah is trying to run a certain number of miles by the end of the month. If Sarah is 80% of the way to achieving her goal and she has already run 40 miles, how many miles is she trying to run by the end of the month?
Answers
Answer: 50 miles
Step-by-step explanation:
Let the miles that she is trying to run by the end of the month be denoted by x.
Since she is 80% of the way to achieving her goal and she has already run 40 miles. This can be expressed as:
80% of x = 40
80/100 × x = 40
0.8x = 40
x = 40/0.8
x = 50
The miles that she is trying to run by the end of the month is 50 miles.
