The sum of three numbers is 66. The second number is 2 times the third. The first number is 10 less than the third. What are the

Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

Let the three numbers be x, y, z

So from the problem given we can get the equations as :

x + y+z= 66

x=2y

z=1x/3

Now we will make equation 1 have only one variable using equation 2 and 3.

y=1x/2 since x=2y

Now using equations 1, 3 and 5 we will get

x+1x/2+1x/3=66

11x/6=66

x= 66*6/11

x= 36

y=x/2=36/2=18

z=x/3=36/3=12

Therefore:

x = 36

y=18

z=12

A garden has the shape of a circular sector such that its straight sides measure 50 feet in length and the central angle is 132°

SOVA2 [1]

Answer:

215 ft

Step-by-step explanation:

The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...

s = r·θ . . . . . where θ is the central angle in radians

<h3>arc length</h3>

There are π radians in 180°, so the arc will have a measure in radians of ...

θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians

Then the length of the curved side of the garden is ...

s = (50 ft)(2.3038 radian) ≈ 115.2 ft

<h3>perimeter</h3>

The fence length is the sum of the arc length and the two radii:

perimeter = 115.2 ft + 2×50 ft = 215.2 ft

About 215 feet of fencing are needed to enclose the garden.
