Answer:

1/14

Step-by-step explanation:

Change the fractions to have a common denominator. The simplest choice for denominator is to just multiply the denominators, i.e., we want to go to /2 * /7 = /14.

So 1/2 = 7/14 and 3/7 = 6/14.

1 whole is 14/14.

14/14 - 7/14 - 6/14 = 1/14

For the function f(x) = (x − 2)2 + 4, identify the vertex, domain, and range.

DanielleElmas [232]

I think the correct answer from the choices listed above is option D. For the function f(x) = (x − 2)2 + 4, the <span>vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.</span>

Cecilia made an envelope to mail a letter. She colored the regular trapezoid flap on the bottom of the envelope blue,

Katen [24]

Answer:

14 inch ^2

Step-by-step explanation:

Area of a trapezium= (a+b) 2 times h

so side a= 5 inches

side b= 9 inches

then times by 2 times the height (2)

you can rearrange the formula to this- a + b/ 2 times height.

5+9/2 times 2= 14

I hope this helps, have a lovely day.

At a museum you can see the four cable lines that are used to pull cable cars up and down a hill. Each cable travels at a speed

borishaifa [10]

Answer:

54.514 rev/min

Step-by-step explanation:

Data provided in the question:

Speed of the cable car = 12.65 miles per hour

Diameter of the rotating wheel, d = 6.5 feet

Now,

The speed of rotation of the wheel will be equal to the speed of the cable car

thus,

The speed of rotation of the wheel = 12.65 miles per hour

also,

1 miles = 5280 feets

1 hour = 60 minutes

Thus,

The speed of rotation of the wheel = $\frac{12.65\times5280}{60}$

= 1113.2 ft/ min

Circumference of the wheel = πd

= 6.5π feet

= 20.42 feet

Therefore,

The speed of rotation of the wheel in revolutions per minute

= 1113.2 ÷ 20.42 rev/min

= 54.514 rev/min
