Answer:

42

Step-by-step explanation:

All of a triangles angles equal 180 degrees. We know that one angle is 48 degrees and 1 angles is 90 degrees. We just have to subtract 138 from 180 to get 42.

Answer:

d) XY > RS

Step-by-step explanation:

When comparing triangles, the angle opposite to the side in question determines the length. In this case 99 is greater than 75. Since XY is the side opposite to 99, it is the larger side

Answer:

TZ = 10 units

UY = 12 units

ZW = 11 units

Step-by-step explanation:

Point Z is the centroid of ΔTUV.

Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1

Therefore, TZ = 2(ZX)

TZ = 2(5) = 10 units

UY = UZ + ZY

     = UZ + [tex]\frac{1}{2}(UZ)[/tex]

     = [tex]\frac{3}{2}UZ[/tex]

     = [tex]\frac{3}{2}\times 8[/tex]

     = 12 units

ZW = [tex]\frac{1}{3}(VW)[/tex]

      = [tex]\frac{1}{3}(33)[/tex]

      = 11 units

im stuck on the same problem

The measure of QR, from the triangle TRQ is 16 units.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle PML is similar to triangle TRQ.

From the given triangles.

ML/QR =PM/TR

(7x-9)/(2x+2) = 35/14

(7x-9)/(2x+2) = 5/2

2(7x-9)=5(2x+2)

14x-18=10x+10

4x=28

x=7

Then, QR=2x+2=16 units

Therefore, the measure of QR is 16 units.

Given:

The increase in pressure P is the linear function of the depth d.

[tex]P(d)=0.445d+14.7[/tex]

The cost of dinner is $300 and $10 per students.

To find:

The initial value and rate of change and their interpretation.

Find the cost function C where n is the number of students.

Solution:

The slope intercept form of a linear function is

[tex]f(x)=mx+b[/tex]          ...(i)

where, m is rate of change and b is y-intercept or initial value.

We have,

[tex]P(d)=0.445d+14.7[/tex]        ...(ii)

From (i) and (ii), we get

[tex]m=0.445,b=14.7[/tex]

The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.

Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.

The cost of dinner is $300 and $10 per students.

Let C(n) be the total cost for dinner and n be the number of students.

Fixed cost = $300

Additional cost for 1 student = $10

Additional cost for n student = $10n

Now,

Total cost = Fixed cost + Additional cost

[tex]C(n)=300+10n[/tex]

Therefore, the required cost function is [tex]C(n)=300+10n[/tex].

Answer:

Step-by-step explanation:

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

Changing to slope-intercept form:

2x - 3y = 9         {subtract 2x from both sides}

-3y = -2x + 9        {divide both sides by (-3)}

y = ²/₃x - 3     ⇒    m₁=²/₃   ⇒   m₂=²/₃

The line y=²/₃x+b passes through point (6, 7) so the equation:

7 = ²/₃×6 + b  is true

7 = 4 + b

b = 3

Therefore equation in  slope-intercept form:

                                                     y = ²/₃x + 3

The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3

The equation in slope - intercept form :

2x - 3y = 9

-3y = 9 - 2x

Divide both sides by - 3

y = - 3 + 2/3x

Using the points (6, 7)

7 = c + 2/3(6)

7 = c + 12/3

7 = c + 4

c = 7 - 4 = 3

c = 3

The equation of the parallel line is thus :

Answer:

(-2, -4)

Step-by-step explanation:

Since both equations are equal to y, you can set them equal to each other:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]

Next, solve for x:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]

Finally, substitute the solution for x in one of the equations (or both) to find y:

[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]

[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]

Therefore, the solution to the system of equations is (-2, -4).

Answer: x = 9

Step-by-step explanation:

x can be equal to 9.

Lets plug in 9 to the variable x, in this equation, x -3 = 6.

x - 3 = 6

9 - 3 = 6 (plugged in 9 for x)

So, x = 9.

Answer: 42.82

Step-by-step explanation:

Answer:

Option A. – 3

Step-by-step explanation:

From the question given above, the following data were obtained:

y = 3/4

xy² = 9/16

(x – 4) =?

Next, we shall determine the value of x. This can be obtained as follow:

y = 3/4

xy² = 9/16

x(3/4)² = 9/16

x (9/16) = 9/16

Divide both side by 9/16

x = 9/16 ÷ 9/16

x = 1

Finally, we shall determine the value (x – 4). This can be obtained as follow:

(x – 4)

x = 1

(x – 4) = 1 – 4

= – 3

Answer:

$1473

Step-by-step explanation:

cost of cloth= rs.950

He spent rs.150  for stitching a shirt

total cots= 950+150

total cost=1100

gain= rs.375

we know that

gain= selling price- cost price

substitute

375= selling price- 1100

selling price= 1100+373

selling price=$1473

Hence the selling price is $1473

Answer:

y- intercept = - 2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)

m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then

y = - 4.5x + c

To find c substitute either of the 2 points into the equation

Using (1, - 7), then

- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5

y- intercept c = - 2.5
