Answer:

YZ = 7 , MO = 8

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.

(11)

YZ = [tex]\frac{1}{2}[/tex] MN , that is

3x + 1 = [tex]\frac{1}{2}[/tex] (10x - 6) = 5x - 3 ( subtract 5x from both sides )

- 2x + 1 = - 3 ( subtract 1 from both sides )

- 2x = - 4 ( divide both sides by - 2 )

x = 2

Then

YZ = 3x + 1 = 3(2) + 1 = 6 + 1 = 7

(12)

XY = [tex]\frac{1}{2}[/tex] MO , that is

x - 1 = [tex]\frac{1}{2}[/tex] (3x - 7) ← multiply through by 2 to clear the fraction

2x - 2 = 3x - 7 ( subtract 3x from both sides )

- x - 2 = - 7 ( add 2 to both sides )

- x = - 5 ( multiply both sides by - 1 )

x = 5

Then

MO = 3x - 7 = 3(5) - 7 = 15 - 7 = 8

Answer:

48 grapes,

Step-by-step explanation:

Firstly, let's sum up the ratio,

6+6+12=24

The fraction of grapes is therefore, 6÷24 or ¼

A ¼ of 192 is 48.

Signifying, there are 48 grapes.

Answer:

Same line

Step-by-step explanation:

5y - x = 5                           y - 1/5x = 1

5y = x + 5                           y = 1/5x + 1

5y/5 = x/5 + 5/5

 y =  1/5x + 1

Answer:

a(66) = -10 + 17(65) = 1095

Step-by-step explanation:

We know that this is an arithmetic sequence.  Subtracting -10 from 7 results in 17; subtracting 7 from 24 also results in 17.  Thus, the common difference, d, is 17.  The first term is -10.

The general form of an arithmetic sequence is a(n) = a(1) + d(n - 1).

Substituting -10 for a(1) and 17 for d, we get:

a(n) = -10 + 17(n - 1)

Now let n = 66:  a(66) = -10 + 17(66 - 1), or    a(66) = -10 + 17(65) = 1095

Answer:

The perimeter of this triangle is 33m.

We can find this by knowing a few things.

1. All sides of this triangle are the same because all the angles are the same.

2. This is an equilateral triangle.

The first thing we need to do is find out what x equals. We can do this by taking 2 of the equations and setting them up like so...

[tex]( 7x - 17 ) = ( 4x - 5 )[/tex]

Then we can plug this into a calculator and find out that x equals 4. And from there we can plug that x value into the equation. And since all sides are the same we just need to find the length of one side and multiply that by 3. So...

[tex]2x+3 = (2*4) +3[/tex]

Then we do some simple math to find that one side has a length of 11m so the entire perimeter is 33.

Answer:

-74

Step-by-step explanation:

f(x) = -2x^2 +8x -10

Let x = -4

f(-4) = -2 ( -4)^2 +8(-4) -10

    = -2(16) -32-10

    = -32 -32-10

   = -74

Comparing the numbers, it is found that the tenths value first determines which of the numbers 6.399 or 6.400 is the larger number.

The decimal numbers are 6.399 and 6.400.

The tenths digit is the first in which there is a difference, hence, it determines which of the numbers 6.399 or 6.400 is the larger number.

Step-by-step explanation:

Answer:

12. 108 degrees

13. 150 degrees

15. 40 degrees

16. 30 degrees

Step-by-step explanation:

12. 540 is the total degrees inside a pentagon, and since it is regular (every side is equal) you divide 540/5 to get 108

13. 1800 is the total degrees inside a dodecagon, and since it is regular (every side is equal) you divide 1800/12 to get 150

15. 1260 is the total degrees inside a nonagon however since it is asking for the exterior angle you take 1260/9 to get 140 and since every straight line is 180 degrees you subtract 140 from 180 to get 40 degrees.

16. 1800 is the total degrees inside a 12-gon (dodecagon) however since it is asking for the exterior angle you divide 1800/12 to get 150 degrees which since every straight line is 180 you subtract 150 from 180 to get 30 degrees.

Algebraic inequalities can be solved in the same way in which algebraic equations are solved.

Using the slope - intercept format, the equation which models the data represented by the graph is d(t) = -50t + 300

According to the general form of a linear regression equation :

Slope, b = (Δy ÷ Δx)

Slope = (200 - 50) ÷ (2 - 5)

Slope = 150 ÷ -3 = -50

Intercept is the point where the regression line crosses the y - axis.

From the graph, the intercept = 300

Hence, the regression equation is y = -50t + 300
