How many sides does a 27-gon have?

Answer:

C. (-1, 3)

Step-by-step explanation:

Label the 2 equations:

5y= 7x +22 -----(1)

x= -6y +17 -----(2)

Substitute (2) into (1):

5y= 7(-6y +17) +22

5y= -42y +119 +22 (Expand bracket)

5y= -42y +141 (Simplify)

42y +5y= 141 (+42y on both sides)

47y= 141

y= 141 ÷47 (÷47 on both sides)

y= 3

Substitute y= 3 into (2):

x= -6(3) +17

x= -18 +17

x= -1

Thus, the solution is (-1, 3).

Answer:

2x - 15 +21 = -18

2x + 6 + 18 = 0

2x + 24 =0 ...it is a linear equation

if u want to solve for X then..

2x = -24

X = - 24

Answer: V= 100.48 m^3 or in terms of Pi V = 32 π m^3

Step-by-step explanation:

V = πr^2h

V = π(2)^2(8)

V = π(4)(8)

V = 100.48

or

V = π (4)(8)

V = 32 π m^3

Answer:

336 cm^2

Step-by-step explanation:

Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.

The next one the 6X13  one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.

Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get

336 cm^2

Step-by-step explanation:

The required, seat width is the continuous variable in the given table.

Continuity is a mathematical concept that describes the smoothness of a function or a curve. A function is said to be continuous if there are no abrupt changes or breaks in the values it takes as the input varies. More formally, a function f(x) is continuous at a point x = a if the limit of f(x) as x approaches a from both sides exists and is equal to f(a).

For example, a function that describes the temperature in a room as a function of time is continuous if there are no sudden changes or jumps in the temperature.

Here,
The number of seats is not a continuous variable because it can only take discrete values (such as 120, 225, etc.).

The Wi-Fi and first-class variables are not continuous either because they are categorical variables that can only take a limited number of values (yes or no).

The seat width variable, however, is a continuous variable because it can take on any value within a range of values (such as between 19.9 inches and 20.6 inches). Therefore, seat width is the continuous variable in the given table.

Answer:

D. A value of 0.9 is more than 2 standard deviations from the mean.

Step-by-step explanation:

A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)

B is wrong, because the mean is exactly 0.5

C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.

Answer:

Step-by-step explanation:

I hope you want the area.

Area = L * W

L = 24x^3

W = 5x^2

Area = 24x^3 * 5x^2

Area = 120 * x^(3 + 2)

Area = 120 * x^5

Note

When you multiply numbers or letters that have powers, if the base for both of them is the same, the powers are added.

The above answer is an example x^2 * x ^3 are letters (x) that are raised to the 2nd power and the 3rd power. You add the powers.

Numbers can do the same thing

Find the area of the composite figure round to the nearest tenth

Answer:

Step-by-step explanation:

(25 x 12) + (10 x 6)

round it 360 >>>>> 360 it is the same

Answer:

360

Step-by-step explanation:

Split the given figure up into two different rectangles. One of these rectangles will have the dimensions (12 and 25), while the other will have the dimensions (6 and 10)  Find the area of each rectangle using the general formula                ([tex]length * width = area[/tex]), then add the two areas up to find the total area of the figure.

12 * 25

= 300

6 * 10

= 60

300 + 60

= 360
