Answer:

  26.13 ft²

Step-by-step explanation:

The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.

  Semicircle area = (1/2)(πr²)

  semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²

The area of the two right triangles is ...

  total triangular area = (3 ft)(4 ft) = 12 ft²

Then the area of the figure is ...

  figure area = semicircle area + total triangular area

  = 14.13 ft² + 12 ft² = 26.13 ft²

In a survey of 2300 people who owned a certain type of​ car, 1035 said they would buy that type of car again. What percent of th
vivado [14]

Answer:

45%

Step-by-step explanation:

1. We assume, that the number 2300 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 2300, so we can write it down as 100%=2300.

4. We know, that x% equals 1035 of the output value, so we can write it down as x%=1035.

5. Now we have two simple equations:

1) 100%=2300

2) x%=1035

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=2300/1035

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1035 is what percent of 2300

100%/x%=2300/1035

(100/x)*x=(2300/1035)*x       - we multiply both sides of the equation by x

100=2.2222222222222*x       - we divide both sides of the equation by (2.2222222222222) to get x

100/2.2222222222222=x

45=x

x=45

Pls help me on this what is the correct answer
goblinko [34]

Answer:

<u>C 61,705</u>

Step-by-step explanation:

10.9% of 35,000 = 3,815

3,815 x 7 = 26,705  (interest is added per year and 3,815 is the interest amount)

35,000 + 26,705 = 61,705 ( the original loan plus the interest for 7 years)
