Solutions: x = ( , )
Insert a picture of the graph below:

Answer:

x= 20, y=95

Step-by-step explanation:

If you see the x angle, it makes 90 degree, and the straight line divides that angle into two. So by that;

x+25=45

x=20

Now if you add up all the angles on the straight line, it makes 180 degree,

by that,

x+25+y+40=180 (straight lines' angle=180 degree)

we now know that x=20, so now by adding that value, we get

20+25+y+40=180

y=180-40-25-20

y=180-85

y=95.

Step-by-step explanation:

Area of triangular prism =1/2 ×base×height

550=1/2×22×h

h=550/11

h=50m

hope it helps.

Answer:

height = 50 m

Step-by-step explanation:

Area of a triangle = 1/2* base * height

550 = 1/2 * 22 * height

550 = 11 * height

therefore, 550/11 = height

therefore, height = 50 metres

Answer:

L=(8x^2+3)/x

Step-by-step explanation:

The area of a rectangle is length time width.

A=LW

In this case,

A=32x^2+12

W=4x

Solve for L

L=A/W

Substitute

L=(32x^2+12)/4x

L=(8x^2+3)/x

Answer:

18 years

Step-by-step explanation:

let the boy's age my x and mother's age be y

x+y=48

y=3+2x which can also be written as 2x-y=-3

on solving both the equations,

you will get x=15 and y=33

so son's age is 15 years and mom's age is 33 years and the difference between their ages is 18

Answer:The equation wth x in the information can be written as

1/2 x = 38.5 , Upon solving, the number = 77

Step-by-step explanation:

Let the number Sara was thinking about be x

halving the number to get an answer = 38.5 can be expressed as

 1/2 X = 38.5

The equation with x in the information can be written as

1/2 x = 38.5

solving it becomes

1/2 x= 38.5

x = 38.5 x 2

x=77

The number Sara was thinking about = 77

Answer:

RT=108

Step-by-step explanation:

Consider ΔQST:

Use pythagorus's theorem.

a²=b²+c²

QS²=QT²+ST²

53²=QT²+28²

2809-784=QT²

QT=√2025=45

Consider ΔQRT:

Use pythagorus's theorem.

a²=b²+c²

QR²=QT²+RT²

117²=45²+RT²

13689-2025=RT²

RT=√11664=108

Answer:

ASA

Step-by-step explanation:

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!

Answer:

  11.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation:

  Cos = Adjacent/Hypotenuse

  cos(37°) = x/14

  x = 14·cos(37°) ≈ 11.1809

The value of x is about 11.2.

Answer:

The cost of the house after one year = 84,750 rupees

Step-by-step explanation:

Explanation:-

Given that the cost of house = 13% in one year

Given that the house original price = 75000

We have to find that the house cost after one year

Solution:-

The cost of a house increase 13% per year

                        = 75000 X 0.13

                       = 9750

The total cost = 75000+9750

                      = 84,750 rupees

Final answer:-

The cost of the house after one year = 84,750 rupees

Answer:

2. (1) [tex]30[/tex]

3. (1) [tex]y=\frac{1}{4}x[/tex]

4. a) [tex]y=x+6[/tex]   b) [tex]42[/tex]

Step-by-step explanation:

In a proportional relationship, y=2 when x=8, the following lines will show this relationship,

1.   y = 1/4x

2.  y = x - 6

4.  y =  1/2x - 2

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that,

The point,

x = 8 and  y = 2

We have to check all the given options,

1.   y = 1/4x

     y  = 1/4 × 8

     y  =  2

2.  y   = x - 6

         = 8 - 6

    y   =  2

3.  y   = 4x

         = 4 × 8

    y   = 32

4.  y   = 1/2x - 2

         = 1/2 × 8 - 2

         =  2

Hence, Option 1, 2, & 4 satisfies the given condition
