6. Polygon ABCD is rotated 270 degrees
counterclockwise around the origin.

Identify the coordinates of B'. Write your response
in the form (x,y)?

Answer:

Step-by-step explanation:

Opposite sides of a parallelogram are congruent:

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

2

X = -12

Answer:

Is that simultaneous equation

Answer:

Solve the system of equations using the substitution method.  Show your work and be sure to include the solution to the system.

Question:

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

I did it on khan

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

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:

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:

6

Step-by-step explanation:

1/2 x (6 x 4) ÷ 3 + 2  

(We do the equation in the parenthesis 1st)

1/2 x 24 ÷ 3 + 2    

(Since it's multiplication and division, we just go from left to right)

4 + 2

6

Answer:

4 + x

Step-by-step explanation:

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

Answer:

100.03

Step-by-step explanation:

i think it is correct

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

I think its 13
