Answer:

X = 116

Step-by-step explanation:

Total heptagon angle = 900

124 + 120 + 122 + 136 + 144 + 138 = 784

900 - 784 = 116

Step-by-step explanation:

Answer:

y = 16

Step-by-step explanation:

you can set 6x - 13 and 8x - 61 equal to each other because they are Alternate-Exterior angles and are congruent; this will give you the value of 'x'

6x - 13 = 8x - 61

-13 = 2x - 61

2x = 48

x = 24

3y + 1 + 8x - 61 = 180   (they form a straight line)

substitute 24 for 'x'

3y + 1 + 8(24) - 61 = 180

3y + 132 = 180

3y = 48

y = 16

Answer:

its the second one

Step-by-step explanation:

its the second one because the statement RWS=TUV shows which angles are congruent in order meaning that ang r and t are congruent angle w and u are congruent and angle v and s are congruent. so t and s are not congruent

Given:

The  function that represents how the amount of fuel changes as a function of distance flown is

[tex]f(x)=-0.9x+665[/tex]

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

[tex]y=mx+b[/tex]        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

[tex]f(x)=-0.9x+665[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=-0.9[/tex]

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

Answer:

ABCD is a trapezoid which has two equal sides => this is an isosceles trapezoid

=> BAD = CDA

=> BAD = 37⁰ + 34⁰ = 71⁰

because AD//BC

=> BAD + ABC = 180⁰

=> ABC = 180⁰ - BAD = 180⁰ - 71⁰ = 109⁰

but i tried

Step-by-step explanation:

y - x = 3x +2

y=3x+x+2

y=4x+2.......(1)

2x + 2y = 14 - y

2x+2y+y=14

2x+3y=14.........(1)

substituting value of y in equation 1

2x+3(4x+2)=14

2x+12x+6=14.

14x=14-6

14x=8

x=8/14=4/7

substituting value of x in equation 1

y=4×4/7+2=30/7

x=4/7

y=30/7

61° is the measure of <STW

To solve this problem, we need some angle geometry knowledge

Given: <SRT = 44°, <RST = 9x+3, <RTW = 14x+7

<RTW = <SRT + <RST (exterior angle of a triangle is equal to the sum of opposite interior angles)

14x+7 = 44 + 9x+3

14x -9x = 44+3-7

5x = 40

x = 40/5 = 8

<STW + <RTW = 180 (sum of angles on a straight line)

<STW = 180 - <RTW

<STW = 180 - (14x+7)

Substitute x = 8:

<STW = 180 - (14(8) +7)

<STW = 180- 119 = 61°

Therefore, the measure of <STW is 61°

Answer:

It will take 10.63 years.

Step-by-step explanation:

Giving the following information:

Present value (PV)= $4,000

Future Value (FV)= $10,000

Interest rate (i)= 9% annual compounded

To calculate the time required to reach $10,000, we need to use the following formula:

n= ln(FV/PV) / ln(1+i)  

n= number of years

n= ln(10,000 / 4,000) / ln(1.09)

n= 10.63

It will take 10.63 years.

Answer:

i) The area of the plot of land is 15,000 m²

ii) The base area of the school is 2,000 m²

iii) The volume of the school building is 30,000 m³

iv) The perimeter of the plot of land is 500 m

v) The cost of fencing the plot of land is Rs 2,500

Step-by-step explanation:

The parameters of the land, the school building and the cost of fencing are;

The length of the land, l = 150 m

The breadth of the land, b = 100 m

The dimensions of the school = 50 m × 40 m × 15 m

The cost of fencing the plot per meter = Rs 50 per meter

i) The area of the plot of land, A = Length × Breadth

∴ A = 150 m × 100 m = 15,000 m²

The area of the plot of land, A = 15,000 m²

ii) Taking the height of the school, h = 15 m, the length of the school building, [tex]l_B[/tex] = 50 m, and the breadth of the school building, [tex]b_B[/tex] = 40 m, the base area of the school, [tex]A_B[/tex], is given as follows;

[tex]A_B[/tex] = [tex]l_B[/tex] × [tex]b_B[/tex]

∴ [tex]A_B[/tex] = 50 m × 40 m = 2,000 m²

iii) The volume of the school building, V = h ×  [tex]l_B[/tex] × [tex]b_B[/tex]

∴ V = 15 m × 50 m × 40 m = 30,000 m³

iv) The perimeter of the plot of land, P = 2 × l + 2 × b

∴ P = 2 × 150 m + 2 × 100 m = 500 m

The perimeter of the plot of land, P = 500 m

v) The cost of fencing the plot of land, C = P × (The cost of fencing the plot per meter )

∴ C = 500 m × Rs 50/m = Rs 2,500

The cost of fencing the plot of land, C = Rs 2,500
