Sofia ordered sushi for a company meeting. They change plans and increase how many people will be at the
meeting, so they need at least 100 pieces of sushi in total.
Sofia had already ordered and paid for 24 pieces of sushi, so she needs to order additional sushi. The sushi
comes in rolls, and each roll contains 12 pieces and costs $8.
Let R represent the number of additional rolls that Sofia orders.

Can some body check my math on this one(question #6) I think it’s n=26 am I right?
Answers
Answer:
[tex]n=26[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-413.4=-15.9n[/tex]
To figure out the value of n, divide both sides by -15.9. The right will cancel. Thus:
[tex]n=(-413.4)/(-15.9)[/tex]
Use a calculator:
[tex]n=26[/tex]
So, the answer is 26.
So, yes, you are very correct!
Answer:
n=26
Step-by-step explanation:
We are given the equation:
[tex]-413.4=-15.9n[/tex]
We want to solve for the unknown variable, which is n. Therefore, we must isolate n on one side of the equation.
n is being multiplied by -15.9. The inverse of multiplication is division. Divide both sides of the equation by -15.9
[tex]\frac{-413.4}{-15.9} =\frac{-15.9n}{-15.9}[/tex]
[tex]\frac{-413.4}{-15.9}=n[/tex]
[tex]26=n[/tex]
Let's check our solution. Plug 26 in for n and solve.
[tex]-413.4=-15.9n[/tex]
[tex]-413.4=-15.9(26)[/tex]
Multiply -15.9 and 26.
[tex]-413.4=-413.4[/tex]
This checks out, so we know our solution is correct.
The solution to this equation is n=26 and you are correct!

You are going shopping for some new sweaters, t-shirts, and pants. Sweaters (s) cost $29, t-shirts (t) cost $16, and pants (p)
cost $25. What algebraic expression models the total cost of clothes that you buy?
Suppose you bought 28 sweaters, 7 t-shirts, and 17 pairs of pants. How much did you spend?
Answers
Answer:
You spent $1349
Step-by-step explanation:
sweaters s = $29
t-shirts t = $16
pants p = $25
Cost = C
28s + 7t + 17p = C
28 ($29) + 7 ($16) + 17 ($25) = C
$812 + $112 + $425 = C
$1349 = C

Jamie is sewing her own dress for the school dance. She bought 2 1/4 yards of fabric. The total cost was $10. What was the cost per yard?
Answers
Answer:
$4.44
Step-by-step explanation:
Cost per yard = $10/2.25
= $4.44 (nearest cent)
the answer $ 4.44
explanation :
so first of all you need to divide 10 by 2 1/4
when you divide both number you'll get 4 4/9
4 4/9 can also be written as 4.44444444444
which is also 4.4 recurring
now we can round this off
when you round it off, you should round it off to two decimal points cause the answer should be in dollars
you should get 4.44 as an answer
so the answer will be $ 4.44

What exactly are mathematical operations?In mathematics, an operation is a function that converts zero or more input values into a discrete output value. The number of operands in the operation determines how difficult it is. The order of operations refers to the rules that outline the sequence in which certain operations should be carried out in order to solve an expression. The following is the order of operations: parentheses, exponents, multiplication, division (from left to right), addition, and subtraction. PEMDAS (from left to right) (from left to right).
So, Florida is warmer than Texas by:
Florida's coldest temperature is -2°F.Texas's coldest temperature is -23°F.Now, calculate as follows:
23 - 221°FTherefore, after conducting some mathematical operations, we can conclude that Florida is warmer than Texas by 21°F.

Does the display appear to be reasonably symmetric about a representative value, or would you describe its shape in some other way?c. Do there appear to be any outlying strength values?d. What proportion of strength observations in this sample exceed 10 MPa?
Answers
Answer:
(a) Shown below
(b) Positively Skewed
(c) No Outlier
(d) 15%
Step-by-step explanation:
Arrange the data set in ascending order as follows:
S = {5.7 , 6.2 , 6.3 , 6.5 , 6.8 , 6.8 , 7 .0, 7 .0, 7.2 , 7.3 , 7.4 , 7.6 , 7.7 , 7.7 , 7.8 , 7.8 , 7.9 , 8.1 , 8.2 , 8.7 , 9 .0, 9.7 , 9.7 , 10.6 , 11.5 , 11.6 , 11.8}
(a)
Construct a stem-and-leaf display of the data as follows:
5 | 7
6 | 2 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 6
11 | 5 6 8
The representative strength value is the mid-value.
The mid-value is: 7.7
Thus, the representative strength value is 7.7.
(b)
No, the data does not appear to be highly concentrated about the representative value or rather spread out.
As we take the stem-and-leaf plot into consideration we observe that most of the observations are concentrated towards the right of the graph.
So, the data is right or positively skewed.
(c)
No, there doesn't appear to be any outlying strength values.
This is because all the values are closer to each other and none of the observations are too extreme.
(d)
The number of observations more than 10 MPa is, 4.
Total number of observations, 27.
Compute the proportion of strength observations that exceed 10 MPa as follows:
[tex]P(>10\ \text{MPa})=\frac{4}{27}=0.14815\approx 0.15[/tex]
Thus, the proportion of strength observations that exceed 10 MPa is 15%.

The total gains of Jack if, In the first play, he gained 12 yards, in the second play lost 15 yards, in the third play gained 25 yards, and in the fourth play lost 2 yards is 20 yards.
What is Subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.
Given:
In the first play, he gained 12 yards, in the second play lost 15 yards, in the third play gained 25 yards, and in the fourth play lost 2 yards.
Assume the gains can be denoted by positive and loss by negative,
Gains = 12 yards, 25 yards.
Total gain = 12 + 25 = 37 yards
Loss = -15 yards, -2 yards
Total loss = -15 + (-2) = -17 yards
Calculate the total gain as shown below,
Total gain = total gain + total loss
Total gain = 37 + (-17)
Total gain = 20 yards.

Calculus 2 master needed; stuck on evaluating the integral please show steps [tex]\int {sec(x/2)tan^5(x/2)} \, dx[/tex] I am thinking that we want to split up the tan^5, making [tex]\int {sec(x/2)tan^2 tan^3(x/2)} \, dx[/tex] and then [tex]\int {sec(x/2)*sec^2x-1* tan^3(x/2)} \, dx[/tex] but I am not sure this is correct. Can anyone help? The thing I am unsure of is that tan^3 is still odd, so would we do the same thing again and factor so we will be left with just tanx?
Answers
Answer:
[tex]\displaystyle \int \sec\left(\frac{x}{2}\right)\tan^5\left(\frac{x}{2}\right)dx=\frac{2\sec^5\left(\dfrac{x}{2}\right)}{5}-\frac{4\sec^3\left(\dfrac{x}{2}\right)}{3}+2\sec\left(\frac{x}{2}\right)+C[/tex]
Step-by-step explanation:
We want to find the integral:
[tex]\displaystyle \int \sec\left(\frac{x}{2}\right)\tan^5\left({\frac{x}{2}\right)dx[/tex]
First, perform the substitution y = x / 2. This yields:
[tex]\displaystyle dy = \frac{1}{2} \, dx \Rightarrow dx = 2\, dy[/tex]
Hence, the integral becomes;
[tex]\displaystyle =2\int \sec y\tan^5 y \, dy[/tex]
Next, as you had done, let's expand the tangent term but to the fourth:
[tex]\displaystyle =2\int \sec y\tan^4 y\tan y\, dy[/tex]
Recall that:
[tex]\tan^2(y)=\sec^2(y)-1[/tex]
Hence:
[tex]\displaystyle =2\int \sec y(\sec^2 y-1)^2\tan y\, dy[/tex]
We can use substitution once more. This time, let u = sec(y). Hence:
[tex]\displaystyle du = \sec y \tan y \, dy[/tex]
Rewrite:
[tex]\displaystyle =2\int \left((\sec^2y-1)^2\right)\left(\sec y \tan y\right)dy[/tex]
Therefore:
[tex]\displaystyle = 2\int (u^2 - 1)^2\, du[/tex]
Expand:
[tex]\displaystyle =2\int u^4-2u^2+1\, du[/tex]
Reverse Power Rule:
[tex]\displaystyle = 2\left(\frac{u^5}{5} - \frac{2u^3}{3} + u\right) + C[/tex]
Simplify:
[tex]\displaystyle = \frac{2u^5}{5} - \frac{4u^3}{3} + 2u + C[/tex]
Back-substitute:
[tex]\displaystyle = \frac{2\sec^5 y }{5}-\frac{4\sec^3 y}{3}+2\sec y+C[/tex]
Back-substitute:
[tex]\displaystyle =\frac{2\sec^5\left(\dfrac{x}{2}\right)}{5}-\frac{4\sec^3\left(\dfrac{x}{2}\right)}{3}+2\sec \left(\frac{x}{2}\right)+C[/tex]
Therefore:
[tex]\displaystyle \int \sec\left(\frac{x}{2}\right)\tan^5\left(\frac{x}{2}\right)dx=\frac{2\sec^5\left(\dfrac{x}{2}\right)}{5}-\frac{4\sec^3\left(\dfrac{x}{2}\right)}{3}+2\sec\left(\frac{x}{2}\right)+C[/tex]
Answer:

Step-by-step explanation:
∫sec(x/2) tan⁵(x/2) dx
apply u substitute u = x/2
= ∫sec(u) tan⁵(u) * 2du
= 2 * ∫sec(u) tan⁴(u) tan(u) du
= 2 * ∫sec(u) (tan²(u))² tan(u) du
= 2 * ∫sec(u) (-1 + sec²(u))² tan(u) du
apply u substitute v = sec(u)
= 2 * ∫(-1 + v²)² dv
expand
= 2 * ∫1 - 2v² + v⁴ dv
sum
= 2 (v - 2v³ + v⁵ )
3 5
substitute it back
= 2 (sec (x/2) - 2sec³(x/2) + sec⁵(x/2) )
