Answer:

Step-by-step explanation:

In geometry, a chord is defined as any line that joins two points of the circumference.

So, in the given graph we have that AC, AB, EB are chords, because they joint two points of the circumference.

On the other hand, FE, FD, FC, FA, FB are not chords, because they only joint a point on the circumference with the center, so they represent the radius.

Therefore, among the options A. FE doesn't represent a chord.

A, FE as a chord is a straight line that goes from one end of the circle to another end. This means both ends of the line should touch the circumference. In FE, only one end of the line is touching the circumference. The other isn't. There FE isn't a chord for circle F

x - the temperature

y - the number of people

the temperature is between 75 degrees and 110 degrees:

75 < x < 110

ololo11 [35]

Answer:

Cost of the hand towels is $2 and cost of the bath towels is $7 .

Step-by-step explanation:

Let us assume that the cost of hand towels be x .

Let us assume that the cost of bath towels be y .

As given

The owner of two hotels is ordering towels.

He bought 38 hand towels and 31 bath towels for his hotel in Arcadia, spending a total of $293.

Than the equation becomes

38x + 31y = 293

As given

He also ordered 45 hand towels and 71 bath towels for his hotel in Middletown, spending $587.

Than the equation becomes

45x + 71y =587

Multiply the equation 45x + 71y =587 by 31 .

45x × 31 + 71y × 31 = 587 × 31

1395x + 2201y = 18197

Multiply 38x + 31y = 293 by 71.

71 × 38x + 71 × 31y = 293 × 71

2698x + 2201y = 20803

Thus two equations are

1395x + 2201y = 18197

2698x + 2201y = 20803

Subtracting 1395x + 2201y = 18197 form 2698x + 2201y = 20803 .

2698x - 1395x + 2201y - 2201y = 20803 - 18197

1303x = 2606

$x = \frac{2606}{1303}$

x =$ 2

Putting this x = 2 in the equations

1395 × 2 + 2201y = 18197

2790 + 2201y = 18197

2201y = 15407

$y = \frac{15407}{2201}$

y = $7

Therefore the cost of the hand towels is $2 and cost of the bath towels is $7 .
