For each part, first decide which of the three methods sections will most easily enable you to sketch the surface. These are the generalized cylinder method, the surface of revolution method, and the method of slices (traces) for general quadric surfaces. Then apply that method to sketch the surface.

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

Answer:

The answer is 144 square feet.

Step-by-step explanation:

if you are trying to find the sum of the room, then you multiply 10 and 12 which equals 120 then you multiply 8 and 3 and that equals 24, then you add your two answers (120+24) and that equals 144 square feet.

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:

[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.

Answer:

a. 35

Step-by-step explanation:

x - 18 = 17

x = 35

Brand C is the cheapest per ounce among Brand A and Brand B. So option B is the correct answer

Brand A is a 16-ounce can and costs $0.89

Brand B is a 32-ounce can and costs $1.75.

Brand C is sold as three 16-ounce cans and costs $2.65.

If two expressions are connected with equal sign is called equation.

16a=0.89

32b=1.75

3(16c)=2.65

a=0.055

b=0.0546

c=0.0552

Therefore brand B is the cheapest per ounce

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."

Answer:

the equation of a line that passes through the point(0,3) answer is 1.5

Step-by-step explanation:

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.

Answer:

Yes, you've got it correct.

Step-by-step explanation:

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.

Answer:

vertical angle can be 2 and 3. anything opposite from eachother. supplementry angles equal to 180 degrees. like 2 and 4

Step-by-step explanation:

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.
