Step-by-step explanation:

Answer:

m∠N = 41°

Step-by-step explanation:

Here,

In △MNO, m∠M = (6x + 1°) ...(1)

m∠N = (3x - 10°) ...(2)

m∠0 = (x + 19°) ...(3)

Here, We know that the sum of all angles of a triangle is 180°

Then,

(6x + 1°) + (3x - 10°) + (x + 19°) = 180°

6x + 1° + 3x - 10° + x + 19° = 180°

6x + 3x + x + 1° - 10° + 19° = 180°

10x + 10° = 180°

10x = 180° - 10°

10x = 170°

x = 170° ÷ 10°

x = 17°

Now, put the value of x in (1), (2) and (3)

m∠M = (6x + 1°)

= (6(17) + 1°)

= (102° + 1°)

m∠M = 103°

m∠N = (3x - 10°)

= (3(17) - 10°)

= (51° - 10°)

m∠N = 41°

m∠0 = (x + 19°)

= (17 + 19°)

m∠0 = 36°

Thus, The m∠N = 41°

(6x + 1°) + (3x - 10°) + (x + 19°) = 180°

(6(17) + 1°) + (3(17) - 10°) + (17 + 19°) = 180°

103° + 41° + 36° = 180°

180° = 180°

Hence, L.H.S = R.H.S

Answer:

slope is 0

Step-by-step explanation:

Answer:There is no slope to this answer. The slope is undefined

Step-by-step explanation: This is because when you use the slope equation (rise over run) you get 1 over 0, because you rise but don't move on the x axis at all. Since you cannot divide by zero the answer is undefined. The slope would be zero if it was a horizontal line for example 0/1 slope.

Answer:

[tex]8.234 E14=8.234 \times 10^{14}[/tex]

Step-by-step explanation:

The given number is [tex]8.234 E14[/tex]

We need to write this number in standard form.

Any no is given in the standard form is given by :

[tex]N=a\times 10^b[/tex]

Where

a and b is real no and integer

It means,

[tex]8.234 E14=8.234 \times 10^{14}[/tex]

Hence, this is the required solution.

Answer:

get y by itself and simplify

y=3/2x +7

Answer:

−6|=6.

Step-by-step explanation:

Answer:

A)3x + 4y = 8

Step-by-step explanation:

Given expression;

          y = [tex]\frac{4}{3} x[/tex]   - 7

A line perpendicular to this will have negative inverse slope;

  the slope of the given line = [tex]\frac{4}{3}[/tex]

  perpendicular line  = [tex]-\frac{3}{4}[/tex]  

 Now;

      the equation of the line is;

           y =  [tex]-\frac{3}{4}[/tex] x  - 7

  multiply through by 4

          4y  = -3x - 28

          4y + 3x  = -28

Answer:

MacBook air please

Step-by-step explanation:

Answer:

left edge should measure 1 cm and bottom should measure 2 cm because it has to be scaled

Step-by-step explanation:

1 cm = 3 ft

left side is 2cm wants it to be 3 feet and 1cm = 3 feet so you make it from to cm to 1 cm aka 3 feet and the bottom side 2 cm so that its scaled :)

Answer:

1st one is yes

2nd no

3rd no

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The segment BC  joining the midpoints of 2 sides of the triangle is

Half the length of the third side, that is

x + 31 = 2(x + 19)

x + 31 = 2x + 38 ( subtract x from both sides )

31 = x + 38 ( subtract 38 from both sides )

- 7 = x → A

Answer:

5/6. Is this what u are looking for?

Step-by-step explanation:

Step 1 Simplify:2x(6)-19=-9 to 12x+-19=-9

Step 2 Add 19 to both sides: 12x-19+19=-9+19. You should get 12x=20

Step 3 Divide 12 on both sides: 12x/12=10/12

x=10/12. Simplified= x=5/6

Answer:

h = 8.845 m

Step-by-step explanation:

The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punters kick, and can be represented as the difference of two functions:

[tex]a(t)=1.4t^2\\\\v(t)=12.1t+2.5[/tex]

We need to find h(t) such that, h(t)=v(t)-a(t)

So,

[tex]h(t)=12.1t+2.5-1.4t^2\\\\h(t)=-1.4t^2+12.1t+2.5[/tex]

It is a quadratic equation. When we solve it we get :

[tex]h(t)=8.845\ m, -0.2\ m[/tex]

Neglecting negative value,

h(t) = 8.845 m

So, the ball was at a height of 8.845 m when it was punted.

Answer: Reflect Y-Axis & 10 Units Down

Step-by-step explanation:

Answer:

1 1/2

Step-by-step explanation:

Given that:

Total miles to run = 4 1/2 miles

Number of same distance markers set = 3

The diatances between each marker :

Total distance / number of markers

4 1/2 ÷ 3

9 /2 ÷ 3

9 / 2 * 1 /3

= 9 /6

= 3/2 = 1 1/2

Hence, the distance between each marker = 1 1/2

Answer:

y=-4

Step-by-step explanation:

first,

you find the slope by doing

y2-y1/x2-x1 and getting 0.

then plug into point slope form,

y-y1=m(x-x1)

y-(-4)=0(x-2)

y+4=0

y=-4

Answer:

2333

Step-by-step explanation:

Answer: D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.

Step-by-step explanation:

The table is not included but this should be the correct answer.

Linear relationships which are proportional will have to pass through the origin which is (0,0). This does not mean that on the table, the points (0,0) have to be there.

Even if it does not explicitly appear in the table, so long as the line passes the origin, it is to be considered a proportional relationship. The (0,0) might not appear on the table because only a few points the line passed through were listed but if when the line is plotted, the line goes through (0,0), it is proportional.
