Answer:

  • 7725 ft²

Step-by-step explanation:

<u>Use the formula:</u>

  • A = (b₁ + b₂) h / 2

<u>Substitute the values and calculate:</u>

  • A = (125 + 81)*75/2 = 7725 ft²

7725ft²

Answer:

Solution given:

Area =(b₁+b₂)h/2

where A is area, and b₁ and b₂ are the length of the bases, and h is the height

We have

b₁=125ft

b₂=81ft

h=75ft

Now substituting value we get

Area of trapezoid=(125+81)*75/2=7725ft²

fiasKO [112]

Answer:

Step-by-step explanation:

Answer:

(a) We will form an equation of line from the points given (6,10) and (2,15)

Using:

On substituting the values in the formula above we will get the required equation of line.

On simplification we will get:

(b) We need to tell at day 0 put x=0 in above equation:

Anika worked for 70 hours on the set up crew on the day the fair arrived at the fairgrounds day 0.

Now, we need to tell decrease per day which is equal to the slope of line

To find the slope compare the equation with general equation which is y=mx+c where m is slope

Here, in

 which is the decrease per day.

The sum of 5 consecutive odd numbers is 145. What is the third number in this sequence
vredina [299]

Answer: The 3rd number in the sequence is 29.

Step-by-step explanation: What we have is a sequence of “ODD” numbers and they are consecutive, which means they come one after another with regular intervals. We don’t have any of the numbers but we can start by saying ‘let x represent the first number in the sequence’

With this in mind, we can now assume all other four numbers in the sequence. Therefore if the 1st number is x, the 2nd number would be x + 2, and the the 3rd number would be x + 4, 4th number would be x + 6 while the 5th number would be x + 8.

The reason is that, every odd number is an addition of two to the previous odd number. For instance, if you start with 3, the next odd number would be 3+2 (5), and so on.

Therefore we can now write our consecutive odd numbers as follows;

x + (x + 2) + (x + 4) + (x + 6) + (x + 8)

Remember that all the numbers add up to 145. Therefore,

x + x + 2 + x +4 + x + 6 + x + 8 = 145

5x + 20 = 145

Subtract 20 from both sides of the equation

5x = 125

Divide both sides of the equation by 5

x = 25.

The first odd number is 25, which means the 3rd odd number is 25 + 4.

Therefore the 3rd odd number is 29.

HELP DUE IN 10 MINS!
Scilla [17]

Answer:

\checkmark \text{B. The area of the circle is } 729\pi,\\\checkmark \text{D. The arc length of the sector is } 12\pi

Step-by-step explanation:

Area of a circle with radius r: r^2\pi

Circumference of a sector with radius r: 2r\pi

Area of sector with angle \theta:  r^2\pi\cdot \frac{\theta}{360}.

Arc length of sector with angle \theta: 2r\pi\cdot \frac{\theta}{360}

Using these equations, we get the following information:

Area of circle: 27^2\pi=729\pi

Circumference of a circle: 2\cdot 27\cdot \pi=54\pi

Area of sector: 27^2\pi\cdot \frac{80}{360}=162\pi

Arc length of sector: 2\cdot 27\cdot \pi \cdot \frac{80}{360}=12\pi
