Answer:
11c
Step-by-step explanation:
They are like terms meaning they all have the same variable you can just add them.
4c+c+6c
11c
Answer:
11c
Explanation:
We are given the expression:
4c+c+6c
We can simplify by combining like terms. All three terms have a “c” so they can all be combined.
Factor out a “c” and add the coefficients.
4c+1c+6c
(4+1+6)c
(11)c
11c
4c+c+6c simplified is 11c
your favorite cookie use 2 1/2 cups of flour per batch you use 7 cups how many batches did you make
Number of cups used for making one batch of cookie :-
[tex] = 2 \frac{1}{2} \: cups[/tex]
Number of cups of flour I use = 7
number of batches of cookie I make :-
[tex] = 7 \div 2\frac{1}{2}[/tex]
[tex] = \frac{7}{1} \div \frac{(2 \times 2 + 1)}{2} [/tex]
[tex] = \frac{7}{1} \div \frac{5}{2} [/tex]
[tex] = \frac{7}{1} \times \frac{2}{5} [/tex]
[tex] = \frac{14}{5} [/tex]
[tex] = 2\frac{4}{5} \: batches[/tex]
Therefore , I have made :-
[tex]2 \frac{4}{5} \: batches \: of \: cookies[/tex]

Determine whether or not the function is continuous for the given values of X.
f(x) = x^2-25/x-7 :x=0, x=7,x= -5
Is the function continuous at x=0?
a. Yes, the point is defined, limit f(x) exists, and limit f(x) 0. (Simplify your answer.)
x →c x →0
b. No, the function is not continuous at x=0 .
Answer:
A. Yes, the point is defined, limit f(x) exists, and limit f(x) 0.
Step-by-step explanation:
Let be [tex]f(x) = \frac{x^{2}-25}{x-7}[/tex], a rational function is continuous at a value of [tex]x[/tex] if and only if denominator is different from zero. In particullar, [tex]x-7 \neq 0[/tex].
Then, we find that function is continuous for every value of [tex]x[/tex] except [tex]x = 7[/tex]. Thus, the function is continuous at [tex]x = 0[/tex], which is evaluated below:
[tex]f(x) = \frac{(x+5)\cdot (x-5)}{x-7}[/tex]
[tex]f(0) = \frac{(0+5)\cdot (0-5)}{0-7}[/tex]
[tex]f(0) = \frac{(5)\cdot (-5)}{-7}[/tex]
[tex]f(0) = \frac{-25}{-7}[/tex]
[tex]f(0) = \frac{25}{7}[/tex]
Thus, correct answer is A.

Working together, it takes two different sized hoses 35 minutes to fill a small swimming pool. If it takes 55 minutes for the larger hose to fill the swimming pool by itself, how long will it take the smaller hose to fill the pool on it's own?
Answer:
[tex]96.25[/tex] minutes.
Step-by-step explanation:
The question states that it takes the larger hose [tex]55[/tex] minutes to fill the entire pool on its own. Assume that the larger hose fills the pool at a constant rate. What fraction of the pool would this hose fill in each minute?
The larger hose fills [tex]\displaystyle \frac{1}{55}[/tex] of the pool in each minute. That is: [tex]\displaystyle \frac{1\; \text{pool}}{55\; \rm \text{minutes}} = \frac{1}{55}\; \text{pool} \cdot \text{minute}^{-1}[/tex].
Similarly, assume that the smaller hose is also filling the pool at a constant rate. The question states that it takes [tex]35[/tex] minutes for the two hoses to fill the pool when working together. Therefore, when working together, the two hoses would fill [tex]\displaystyle \frac{1}{35}[/tex] of the pool in each minute. That is: [tex]\displaystyle \frac{1\; \text{pool}}{35\; \rm \text{minutes}} = \frac{1}{35}\; \text{pool} \cdot \text{minute}^{-1}[/tex]
The difference between these two fractions should represent the fraction of the pool that the smaller hose fills in each minute:
The smaller hose fills [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)[/tex] of the pool in one minute. That's [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}[/tex].
At [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}[/tex], filling the entire pool would take
[tex]\displaystyle \frac{1\; \text{pool}}{\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}} = \frac{1}{\displaystyle \frac{1}{35} - \frac{1}{55}}\; \text{minute} = 96.25\; \text{minute}[/tex].
Hence, it would take [tex]96.25[/tex] minutes for the smaller hose to fill the entire pool on its own.
I've got a question I think I've got right. Want to be sure tho
Explanation:
Theoretically, we expect "6" to show up once every 6 rolls assuming we have a fair die. So about 1/6 = 0.17 = 17% of the time.
The table on the other hand shows "6" showing up 14 times out of 100 to get an experimental probability of 14/100 = 0.14 = 14% which is 3 percentage points less than the theoretical estimate.

Yes, you've got it correct.

If 106 people attend a concert and tickets for adults cost four dollars what ticket for a children cost $3.75 and total receipt for the concert was $414 how much of each went to the concert
Answer:
A = 66 adults, C = 40 children
Step-by-step explanation:
We can set up a system of equations to find how many adults and how many children attended the concert, with A representing the adults and C representing the children:
[tex]A + C = 106\\4A+3.75C=414[/tex]
We can use the elimination method and multiply everything in the first equation by -4
[tex]-4(A+C=106)\\-4A-4C=-424\\4A+3.75C=414[/tex]
Once we add the values together, we're left with:
[tex]-0.25C = -10[/tex], where solving for C gives us C = 40
We can plug C into the first equation to find A: [tex]A+40=106[/tex], where solving for A gives us A = 66

Explanation:
Let's say Phil passes his brother at a sign post, and let's say the sign post is x miles into the 6 mile hike. This means 0 < x < 6.
Once Bill reaches the sign post, he turns around to walk back x miles. His faster brother Phil bikes the remaining 6-x miles to the trail end, before coming back to bike an additional 6 miles to get to the trailhead again. Phil arrives back at the same moment Bill does.
Overall, Phil travels 6-x+6 = 12-x miles in the same amount of time Bill walks back x miles. I recommend drawing out a number line diagram to see why this is the case.
-------------
For Bill, we have this equation
distance = rate*time
x = r*t
r = x/t
Phil has the equation
distance = rate*time
12-x = (3r)*t
Notice that Phil's rate is three times that of Bill. The t is the same for both brothers because they travel in the same timespan.
Plug in r = x/t and solve for x. The t variables divide and cancel.
12-x = 3*(r)*t
12-x = 3*(x/t)*t
12-x = 3x
12 = 3x+x
4x = 12
x = 12/4
x = 3
Phil passed Bill at the 3 mile marker.
This is why the answer is choice B.

3. A shoe store marks up its merchandise by 8%. What was the selling price of a pair of shoes whose
wholesale price is $24.50?
(Show The Work)
Answer:
The selling price of the shoes is $26.46.
Step-by-step explanation:
Given the following question:
8% of 24.50
To find the answer we will use the formula to calculate percentages, we multiply the percentage by the cost, then we divide that answer by 100. Finally, we add that answer to the original costs of the shoes to have our answer.
[tex]\frac{p~x~n}{100}[/tex]
[tex]\frac{8~x~24.50}{100}[/tex]
8 × 24.50 = 196
196 ÷ 100 = 1.96
8 of 24.50 is 1.96
Now Add
[tex]24.50+1.96=24.46[/tex]
The selling price of the shoes are $26.46.

Answer:
35 is the answer
*multiply both sides by 7. This leaves you with 5a=175. Then divide both side by 5. Leaving you with a=35
Answer:
[tex]a=35[/tex]
Step-by-step explanation:
Given the following question:
[tex]\frac{5a}{7} =25[/tex]
To find the answer we need to isolate variable in order to find the value of a we are going to have to use inverse of operations to isolate the variable.
[tex]\frac{5a}{7} =25[/tex]
[tex]7\times0=0[/tex]
[tex]25\times7=175[/tex]
[tex]5a=175[/tex]
[tex]\frac{5a}{5} =a[/tex]
[tex]175\div5=35[/tex]
[tex]a=35[/tex]
Your answer is "a = 35."

The graph f(x)=x^2 was transformed to create the graph g(x)=−(3x)^2.
Which statement describes this transformation?
a reflection over the x-axis and a horizontal compression
a reflection over the y-axis and a horizontal compression
a reflection over the y-axis and a vertical compression
a reflection over the x-axis and a vertical compression
Answer:
the first one.
Step-by-step explanation:
the "-" sign simply turns everything upside-down. what was originally above the x-axis is now below it, and what was below the x-axis is now above it. hence : a reflection over the x-axis.
and 3x compared to x simply makes us race "faster" along the x-axis. we get now at x the functional value we would have gotten at 3x with the original function. so, the function graph appears compressed in the left-right (horizontal) direction compared to the original graph.
