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:

p=13

Step-by-step explanation:

let p = people

72.95=5.15p+6

-6

56.95=5.15

/5.15

p=13

Answer:

Equation:5.14x+6=72.95

Answer:13 people

Step-by-step explanation:

5.15x+6=72.95

-6 on both sides

5.15x=72.95

divide by 5.15 on both sides

x=13 people

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.

Answer:

Rounded to the nearest hundredth, is X=4.67

Step-by-step explanation:

A circle, when using degrees, have 360 degrees. 1/360 of a circle can be calculated by multiplying the two numbers.

[tex]\frac{1}{360}*360=1[/tex]

Therefore, the answer for the question is

1/360 of a circle measure 1 degree

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."

Hope this helps.

Answer:

x =< 5

Step-by-step explanation:

We have to solve 2x + 3 <= 13

2x + 3 <= 13

=> 2x =< 13 - 3

=> 2x =< 10

=> x =< 5

Answer:

x > 8

Step-by-step explanation:

[tex]\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}[/tex]

[tex]-2x+3-3 < -13-3[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]-2x < -16[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]

[tex]\left(-2x\right)\left(-1\right) > \left(-16\right)\left(-1\right)[/tex]

[tex]\;Simplify[/tex]

[tex]2x > 16[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]

[tex]\frac{2x}{2} > \frac{16}{2}[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]x > 8[/tex]

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
