Answer:

34

Step-by-step explanation:

if you add 90+56 you get 146 and then 180-146=34

Answer:

a = 34°

Step-by-step explanation:

1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.

2. This means that a + 90 + 56 = 180.

3. (Solving equation above).

Step 1: Simplify both sides of the equation.

Step 2: Subtract 146 from both sides.

Step 3: Check if solution is correct.

Therefore, a = 34°.

Answer:

1st question: 30

2nd question:78

Step-by-step explanation:

use the formula [tex]A=\frac{ab}{2} sin(y)[/tex]]

Where A is the area, a and b are the two given lengths and y is the given angle.

So,

a=9

b=7

y=73

Plugging those values in, we get:

[tex]A=(\frac{9*7}{2})Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)[/tex]

For the 2nd question, we use the same formula, only this time

a=13

b=14

y=59

so,

[tex]A=\frac{13*14}{2} sin(59)\\A=91*Sin(59)\\A=78[/tex]

============================================================

Explanation:

Point R is located at (-2,4)

Shift it to the right 4 units to move it to (2,4). Note how I added 4 to the x coordinate.

Then we subtract 7 from the y coordinate to move it 7 units down. We move from (2,4) to (2,-3) which is where point R' is located.

Check out the diagram below.

Answer:

y = 3x/2-14

Step-by-step explanation:

We are given that the line is perpendicular to y = -2/3 and contains (4,-8).

Perpendicular Def.

[tex] \displaystyle \large{m_1m_2 = - 1}[/tex]

Both slopes multiply each others equal to -1.

Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.

[tex] \displaystyle \large{ - \frac{2}{3} m_2 = - 1}[/tex]

Multiply both sides by 3.

[tex] \displaystyle \large{ - \frac{2}{3} m_2( 3) = - 1(3)} \\ \displaystyle \large{ - 2 m_2= - 3} \\ \displaystyle \large{ m_2= \frac{3}{2} }[/tex]

Therefore, another slope that is perpendicular to -2/3 is 3/2.

Then rewrite in slope-intercept form.

Slope-Intercept

[tex] \displaystyle \large{y = mx + b}[/tex]

where m = slope and b = y-intercept; substitute m = 3/2 in.

[tex] \displaystyle \large{y = \frac{3}{2} x + b}[/tex]

Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.

[tex] \displaystyle \large{ - 8 = \frac{3}{2} (4) + b} \\ \displaystyle \large{ - 8 = 3(2)+ b} \\ \displaystyle \large{ - 8 = 6 + b} \\ \displaystyle \large{ - 8 - 6 = b} \\ \displaystyle \large{ - 14 = b}[/tex]

Therefore, b is -14; rewrite again in slope-intercept form.

Thus:-

[tex] \displaystyle \large{y = \frac{3}{2} x + b} \\ \displaystyle \large{y = \frac{3}{2} x - 14}[/tex]

Answer:

(x-y-1)^2 or [(x-y)-1]^2

Step-by-step explanation:

We are given the expression:-

[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 }[/tex]

Let A = (x-y)^2

[tex] \displaystyle \large{ A^{2} - 2 A+ 1 }[/tex]

From:-

[tex] \displaystyle \large{ {x}^{2} - 2x + 1 = {(x - 1)}^{2} }[/tex]

Thus:-

[tex] \displaystyle \large{ {A}^{2} - 2A + 1 = {( A- 1)}^{2} }[/tex]

Rewrite A in (x-y)^2.

[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 = {( (x - y) - 1)}^{2} }[/tex]

Slope of a parallel line: 3

Step-by-step explanation:

-9x + 3y = 1

3y = 9x + 1

y = 9/3x + 1/3

Slope= 9/3 = 3

The measure of ∠4 = 44°.

We have two angles ∠3 and ∠4 which are complementary of each other.

We have to find the measure of ∠4.

Two angles are said to be complementary if their sum is equal to 90°.

Mathematically -   x + y = 90°

According to the question -

∠3 = 46°

∠4 = x (Let)

Now, ∠3 and ∠4 are Complementary angles. Therefore -

∠3 + ∠4 = 90°

∠4 = 90 - ∠3

∠4 = 44°

Therefore -

∠4 = 44°

Hence, the measure of ∠4 = 44°.

15/11 is a mixed number already, it is 1.363636363636........

Answer:

[tex]1\frac{4}{11}[/tex]

Step-by-step explanation:

You can read [tex]\frac{15}{11}[/tex] as "15 divided by 11"

So to figure out the mixed number, you do just that.

11 goes into 15 1 time, then you subtract 11 from 15, which gives you a remainder of 4. You put 4 as your numerator and 11 is your denominator.

Answer: y = 5/5x - 5

Step-by-step explanation:

Answer:

i think its 27.

Step-by-step explanation:

Let the number of pink marbles  =  p

Let the number of yellow marbles  =  y

The ratio of pink marbles to yellow marbles is 3:5 . This means...

the number of pink marbles / the number of yellow marbles  =  3 / 5

p / y  =  3 / 5

There are a total of 72 marbles in the bag. So...

the number of pink marbles  +  the number of yellow marbles  =  72

p + y  =  72

y  =  72 - p

Now we can use this value of  y  in the first equation and solve for  p .

p / (72 - p)  =  3 / 5

Multiply both sides of the equation by  5 .

5p / (72 - p)  =  3

Multiply both sides by  (72 - p)

5p  =  3(72 - p)

5p  =  216 - 3p

Add  3p  to both sides.

8p  =  216

Divide both sides by  8 .

p  =  27

the number of pink marbles  =  27
