Answer:

y = 50

x = 80

Step-by-step explanation:

An isosceles triangle therefore has both two equal sides and two equal angles.

the 2 equal angles are y and and the one next to the 130 degree

so 180- 130 = 50

y = 50

x = 180 - 50 -50 = 80 degree

Step-by-step explanation:

Answer:

8 and 24

Step-by-step explanation:

let one no. be x

and another be 3x

Their sum = 32

Now,

x + 3x=32

4x=32

x=32/4

x=8

Hence, one number is x =8 and another is 3x = 3*8=24

The two numbers are 6 and 26

From the given statement, we can form the following equations;

Let the first number = x

let the second number = y

The  2 numbers that add up to 32:

x + y = 32 ---------- (1)

If one number is eight more than three times the other:

x = 3y + 8  -------(2)

Substitute the value of x into equation (1) and solve for the second number

3y + 8 + y = 32

4y = 32 - 8

4y = 24

[tex]y = \frac{24}{4} = 6[/tex]

The value of  the first number, x,  is calculated as;

x = 3(6) + 8

x = 18 + 8

x = 26

Thus, the two numbers are 6 and 26

Answer:

1st angle is 28° and the 2nd angle is 62°

Step-by-step explanation:

Complementary angles mean that the angles add up to 90 so:

2x - 2 + 5x - 13 = 90

7x - 15 = 90

7x = 90 + 15

7x = 105

x = 15

Plugging in:

2x - 2

Answer:

1/2 = r

Step-by-step explanation:

7r + 21 = 49r

Subtract 7r from each side

7r-7r + 21 = 49r-7r

21 = 42r

Divide each side by 2

21/42 = 42r/42

1/2 = r

Answer:

r = 0.5

Step-by-step explanation:

First you need to isolate the r variable.

7r + 21 = 49r

-7r          -7r

21 = 42r

Then Divide both sides by 42

0.5 = r

Now check your answer by inserting it back into the original equation.

7(0.5) + 21 = 49(0.5)

3.5 + 21 = 24.5

24.5 = 24.5

The equation is true so r = 0.5

This all depends on the content you are studying, and what learning style works for you. One thing that works for most people is repetition. Although it sucks, it works because that’s how our brains are wired. Tell yourself, “I will not stop studying until I understand this concept or calculation,” for example. Then take a break once you are comfortable with it. Repeat again as needed. Start studying early and only study what you don't know. Try to be as consistent as possible. Good luck!

Answer:

  1a. A, C

  1b. A, B

  2. corresponding points on similar figures are on the same line through the center of dilation

  3. corresponding angles in similar figures are congruent

Step-by-step explanation:

1. Your image is distorted, so it is not easy to draw a "straight" line on the provided graphs.

In problem (a), the top corner of figure B at lower right does not line up with the corresponding corners of figures A and C. Figure B is not similar to the other two.

In problem (b), the corners of figure C do not line up with the corners of figures A and B. Figure C is not similar to the other two.

__

2. Corresponding corners of similar figures will be on the same line through the center of dilation. If a "corresponding" point is not on the line, then the figure is not similar.

We examined lines through corresponding points to see if they went through the center of dilation. If a line does not do that, then the figures are not similar. By looking at (two) pairs of figures we can determine which is not similar to the others.

__

3. The usual properties of interest for similar figures are ...

For dilated figures, the sides will be proportional if corresponding end points are on the same line through the center of dilation and the corresponding sides are parallel.

This is meant to maintain the line spacing. If you want show the full size of the integral (or in display mode), add the \displaystyle tag after the [ tex ] like this

and the integral will look like this

Answer:

the dryer costs $425

Step-by-step explanation:

x = washer

y = dryer

x + y = 803

x = y - 47

using the second equation a substitute in the first equation we get

y - 47 + y = 803

2y = 850

y = $425

FYI

x = y - 47 = 425 - 47 = $378

Answer:

The dryer costs $425

Step-by-step explanation:

803 - 47 = 756

756 / 2 = 378 (price of the washer)

378 + 47 = 425 (price of the dryer)

Step-by-step explanation:

→ Pick 2 coordinates

( 0 , 1 ) and ( 2 , 2 )

→ Find the gradient

[tex]\frac{2-1}{0-2}= -\frac{1}{2}[/tex]

→ Write into y = mx + c

y = -0.5x + c

→ Substitute in ( 0 , 1 )

1 = 0 + c

→ Find c

c = 1

→ Rewrite everything into y = mx + c
