Both the triangles on the left and right are isosceles

The top angle of the triangle on the left:

The top angle of the triangle on the right:

This is the same angle as supplementary with angle 2:

Correct choice is 4

Answer:

A - y = 1200(1+.05)^30

Step-by-step explanation:

In this case, you need to calculate the future value and the formula to calculate that is:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:

FV=1200*(1+0.05)^30

According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Step-by-step explanation:

just put them all into a calculator and multiply them

1/3*23.26*7=54.27333333

Answer:

around 54.27

Step-by-step explanation:

Just multiply the numbers or change them to decimals (1/3 = 0.333 , 23.26, and 7 = 7.0)

1/3 * 23.26 * 7 = 54.273 (repeating)

The area of the triangle, Δ AMN is 8 cm², so the area of the triangle, ΔMCN is 24 cm².

A triangle is one of the most basic geometric figures with 3 sides, 3 angles, and 3 vertices.

The area of a triangle is half of the product of the base and height.

Given that

ABCD is square and M and N are mid-points of lines AB and AD respectively.

Area of triangle, ΔAMN = 8 cm²

[tex]\dfrac{1}{2} \times AN \times AM = 8\\AN \times AM = 8 \times 2\\AN \times AM = 16[/tex] ...(i)

Since ABCD is square, therefore AB = AD.

Also, as M and N are mid-points of lines AB and AD, so

AN = AM.

Substitute AN = AM in equation (i),

[tex]AN \times AN = 16\\AN^2 = 16\\AN = \sqrt{16}\\AN = 4\ cm[/tex]

So,

AD = 2 × AN

     = 2 × 4

     = 8 cm

As ABCD is square,

AB = BC = CD = AD = 8 cm.

Area of the square ABCD = 8² = 64.

Since CD = BC, ND = MB, ∠D = ∠B.

Therefore by SAS property of similarity,

ΔCDN ≅ ΔCBM

Area of the triangle, ΔCDN = Area of the triangle, ΔCBM.

                                              [tex]= \dfrac{1}{2} \times CB \times BM\\= \dfrac{1}{2} \times 8 \times 4\\\\= 16\ cm^2[/tex]

Area of the triangle, ΔCMN = Area of ABCD - Area of ΔAMN - Area of ΔCDN - Area of ΔCBM

Area of the triangle, ΔCMN = 64 - 8 - 16 - 16

                                              = 24 cm²

Therefore, the area of ΔCMN  is 24 cm².

Answer:

  A

Step-by-step explanation:

If x is the side length of the regular pentagon, the perimeter is the sum of its 5 side lengths: 5x. To find the side length, we can use the formula that sets this equal to the known perimeter:

  5x = 47 1/2 . . . . . . mismatch with statement A

Statement A is false.

15cm x 7xm +

7cm x 15cm =

215cm

215cm x 2 = 430 cm squared.

Answer:

It decreased 60%

Step-by-step explanation:

TO figure this out we must first find 1% of 60

60/100 = .6

Now we find the difference between 60 and 24

60 - 24 = 36

Now that we know how much it decreased we must now find out what percent 36 is of 60.

.6 x 60 = 36

So 36 out of 60 is 60%

So it decreased 60%

Answer:

The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;

A y = 3·x

Step-by-step explanation:

The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie

The number of points she will earn for attending each movie = 3 points

The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;

y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write

[tex]y = \sum\limits_{i =1}^x 3 = 3 \times x[/tex]

Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

Answer:

m=-2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

-4x + 7 = 2y - 3

7 = 2y - 3 + 4x

0 = 2y - 3 + 4x - 7

-2y = -3 + 4x - 7

-2y = 4x - 10

y = -2x + 5

As the slope of the line is equal to the value of x, the slope of this line is -2

Answer:

The orginial angle is a right angle (however, the pair of angles would be classified as complementary angles); the value of x is 28.

Step-by-step explanation:

It's important to note that a right angle is always 90°.

90 - 56 = 34

Set up an equation to solve for x:

34 - 6 = x

34 - 6 = 28

28 = x

Now, check if the answer is correct.

Add up both angles' measurements:

56 + (28 + 6) = 90
