Answer:

CPCTC

Step-by-step explanation:

CPCTC (corresponding parts of congruent triangles are congruent)

9514 1404 393

Answer:

Step-by-step explanation:

We assume you want to know how many of each item Rosa bought.

The problem information lets us write two equations:

  x + y = 12

  2x - y = 18

Adding the two equations, we get ...

  3x = 30

  x = 10 . . . . . divide by 3

  y = 12 -x = 2 . . . find y

Rosa bought 10 keychains and 2 magnets.

Answer:

[tex]Average = 71[/tex]

Step-by-step explanation:

Given

Subjects = 7

Marks:  60, 53, 90, 65, 62,85, 82

Required

Determine the average mark

We start by adding the marks together.

[tex]Sum = 60 + 53 + 90 + 65 + 62 + 85 + 82[/tex]

[tex]Sum = 497[/tex]

Then divide the sum by number of subjects

[tex]Average = \frac{Sum}{Subjects}[/tex]

[tex]Average = \frac{497}{7}[/tex]

[tex]Average = 71[/tex]

Hence, the average mark is 71

Answer:

y=8

Step-by-step explanation:

not 100% but I think this is right.

Answer:

D. -(-2/9)

Step-by-step explanation:

Once you distribute the negative sign, it makes the same answer.

-2 times -1 = 2

9 times -1 = -9

2/-9

Answer:

40 ft squared

Step-by-step explanation:

To calculate area of a rectangle, you use the formula length times width, or base times height.

5 x 8 = 40 feet squared

Answer:

g(x)=9x^3-x^2+2 for g(2)

Step-by-step explanation:

g(2)=9.2^3-2^2+2

=18^3-2^2+2

=18^1^4

=18^4

=104,976

Answer:

She paid 1247$ with tax

Step-by-step explanation:

7.5% of 1160$ is 87$ you then add 87 to 1160$ to get 1247$

answer: its $1247

explanation: I had it wrong the first time cause I read it as 1660 instead of 1160 but. you do 1160×.075 yo get your sales tax which is 87 dollars. you then add that to your total.

Answer:

y-6=-3(x+6)

Step-by-step explanation:

Find the slope first, using the slope formula.

y2-y1/x2-x1

-9-6/-1--6 = -15/5

Slope is -3

Put it into point-slope form using one of the coordinates.

y-y1=m(x-x1)

y-6=-3(x+6)

Answer:

x = 25, y = 9

Step-by-step explanation:

Since the triangles are congruent then corresponding angles and sides are congruent, thus

∠ O = ∠ P , substitute values

6y - 14 = 40 ( add 14 to both sides )

6y = 54 ( divide both sides by 6 )

y = 9

and

NG = IT , that is

x - 2y = 7 ( substitute y = 9 into the equation )

x - 2(9) = 7

x - 18 = 7 ( add 18 to both sides )

x = 25

Answer:

x = 70

Step-by-step explanation:

Properties of a parallelogram.

1). Pair of opposite sides of a parallelogram are equal in measure and parallel to each other.

2). Opposite angles of a parallelogram are equal in measure.

3).Adjacent angles of a parallelogram are supplementary.

By the second property,

(2x - 30) = (x + 40)

2x - x = 30 + 40

x = 70

Answer: sin[tex]\frac{a}{2}[/tex] = ± [tex]\frac{1}{\sqrt{26} }[/tex]

Step-by-step explanation:

We very well know that,

cos2A=1−2sin²A

⟹ sinA = ±[tex]\sqrt{(1-} \frac{cos2A}{2} )[/tex]

As required,  set A = [tex]\frac{a}{2}[/tex]   &   cos a=  [tex]\frac{12}{13}[/tex]    ,thus we get

sin [tex]\frac{a}{2}[/tex] =± [tex]\sqrt{\frac{1-cos a}{2} }[/tex]  

∴ sin[tex]\frac{a}{2}[/tex] =±[tex]\sqrt{\frac{1-\frac{12}{13} }{2} }[/tex] = ± [tex]\frac{1}{\sqrt{26} }[/tex]

   since ,360° < [tex]\frac{a}{2}[/tex] <450°

             ,180° < [tex]\frac{a}{2}[/tex] <225°

Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.

hope it helped!
