Answer:

∠ 3 = 60°

Step-by-step explanation:

∠ 1 and ∠ 2 are same- side interior angles and sum to 180° , then

4x + 36 + 3x - 3 = 180

7x + 33 = 180 ( subtract 33 from both sides )

7x = 147 ( divide both sides by 7 )

x = 21

Then

∠ 2 = 3x - 3 = 3(21) - 3 = 63 - 3 = 60°

∠ 2 and ∠ 3 are alternate angles and are congruent, so

∠ 3 = 60°

Answer:

60°

3(21)- 3 = 60

Step-by-step explanation:

4x+36 + 3x-3 = 180

x = 21

Answer:

Step-by-step explanation:

            Statements                               Reasons

1. m∠A = 6x - 10                              1. Given

2. m∠B = 2x                                    2. Given

3. m∠C = 8x - 2                               3. Given

4. m∠A + m∠B + m∠C = 180°         4. Triangle sum theorem

5. (6x - 10) + (2x) + (8x - 2) = 180°   5. Substitution

6. 16x - 12 = 180                              6. Algebra

7. 6x = 192                                       7. Addition property of equality

8. x = 12                                           8. Division property of equality  

4x - 5y = -12

-x + 5y = 18

Add the equations together:

4x + -x = 3x

-5y + 5y = 0

-12 + 18 = 6

So now you have:

3x = 6

Divide both sides by 3:

X = 2

Now you have the value of x, replace x with 2 in one of the equations and solve for y:

4(2) -5y = -12

8 -5y = -12

Subtract 8 from both sides:

-5y = -20

Divide both sides by -5:

Y = 4

The solution is x = 2 and y = 4 which is written as (2,4)

2. a, b, c, d are not prefect squares

3. a and c squares will end with a "1" in the units place.

4. b and c squares will end with a "6" in the units place.

5. a. 17

b. 161

6. 25

7. a. 144 + 145

b. 264 + 265

c. 480 + 481

d. 1012 + 1013

8. a, d, e

9. a. d

Step-by-step explanation:

1. is just plain calculator work

2. a. no perfect square

Property 1: A number having 2, 3, 7 or 8 at unit’s place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8.

2. b. no perfect square

Property 2: The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.

2. c. no perfect square

the same as 2.b.

2. d. no perfect square

the same as 2.a.

2. e. is a perfect square (of 250)

3.

Property 6: The unit’s digit of the square of a natural number is the unit’s digit of the square of the digit at unit’s place of the given natural number.

for 81² : as 1²=1, therefore 81² will also end with a 1.

for 119² : as 9²=81 ends with 1, 119² will also end with a 1.

all others do not meet that criteria.

4.

again Property 6.

44² : 4²=16, therefore 44² will also end with a 6.

126² : 6² = 36, therefore 126² will also end with a 6.

5.

given a number n and its following number n+1, the difference between their squares is

(n+1)² - n² = n² + 2n + 1 - n² = 2n + 1

there cannot be any perfect square number in between n² and (n+1)², as the base number would have to be between n and n+1 (which is impossible).

a. 2×8 + 1 = 17

b. 2×80 + 1 = 161

6. as 5.

2×12 + 1 = 25

7.a.

n + n + 1 = 17²

2n + 1 = 17²

n = (17² - 1)/2 = 144

n+1 = 145

b.

2n + 1 = 23²

n = (23² - 1)/2 = 264

n+1 = 265

c.

n = (31² - 1)/2 = 480

n+1 = 481

d.

n = (45² - 1)/2 = 1012

n+1 = 1013

8.

Property 3: Squares of even numbers are always even numbers and square of odd numbers are always odd.

therefore, only 256, 1296 and 144 can be squares of even numbers.

9.

again Property 3.

therefore, only 529 and 361 can be squares of odd numbers.

Answer:

A. Decreasing linear

Step-by-step explanation:

Divide the amount of tax by the rate of tax.

3.20 / 0.02 = 160

The cost of the camera is $160

If the sales tax in a certain city is 2% and man paid sales tax of $3.20 then the cost of the camera, exclusive of sales tax is $156.80.

Sales tax is the tax that is paid by buyer to seller on the amount of goods sold.

We have been given that sales tax in a certain city is 2% and sales tax paid by man for camera is $3.20 and we have to find the cost of the product excluding sales tax.

Sales tax=tax percentage*total price

3.20=2/100*total price

Total price=3.20*100/2

=$160

Price excluding sales tax=total price - sales tax

=160-3.20

=157.80

Hence if the sales tax in a certain city is 2% and man paid sales tax of $3.20 then the cost of the camera, exclusive of sales tax is $156.80.

Step-by-step explanation:

Answer:

For 25) it's option C. -1/2

For 26) it's option D. 7π/6, 11π/6

Step-by-step explanation:

If you are finding sin−1 of a positive value, the answer will be between 0 and π/2. Using the unit circle, the angle with a sine of 1/2 in the first quadrant is π/6.

Answer:

-1/2

7π/6, 11π/6

Step-by-step explanation:

First problem:

31π/6 = 31/6 π = 5 1/6 π

A full circle is 2π radians. π radians = 180°

Start at 0 radians (positive x axis), and go 5 half circles counterclockwise.

You end up at π radians, or 180°, or the negative x axis.

Now go π/6 radians more counterclockwise.

You end up at 7π/6 or 210°.

Read the y-coordinate of the point on the unit circle.

Answer: -1/2

Second problem:

Look in the figure of the first problem.

The sine corresponds to the y-coordinate.

Look at the points on the circle, below the x-axis, that have a y-coordinate of -1/2.

They correspond to 7π/6 and 11π/6

Answer:

Overall vertical is visually better, if done correctly

it forces you to "line up" all the common exponents.

The disadvantage is that it usually requires re-writing the problem, and it takes up space.

most problems are presented horizontally, that becomes the issue to locate the common exponents.

in both cases the biggest issue is people forget

that when subtracting "subtracting a negative is like adding a positive"

-5x - (-8x)  = 3x [that is a positive 3x]

or:

     -7x

-    - 10x

-------------

     3x

everyone misses those eventually so you have to watch out for that in both methods
