Ksju [112]

1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.

2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.

3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.

4. Calculate by dividing. The answer is 1.5 degrees per hour.

an athletic facility is building an indoor track. the track is composed of a rectangle and two semicircles, as shown. a) write a

stepan [7]

Answer:

(a) P = 2x + 2r + 2πr

(b) x = ½(P - 2r - 2πr)

Step-by-step explanation:

See Attachment for sketch of the track

Solving for (a): Perimeter of the track

This is calculated by adding the perimeter of the rectangle to the 2 semicircles as follows.

P = Perimeter of Rectangle + Perimeter of 2 Semicircles

P = 2(x + r) + 2 * πr

[Where r is the radius of both semicircles]

Open bracket

P = 2x + 2r + 2πr

Solving for (b): Formula for x

P = 2x + 2r + 2πr

Make x the subject of formula

2x = P - 2r - 2πr

Divide both sides by 2

x = ½(P - 2r - 2πr)

Solving for (c): the value of x when r = 50 and P = 660

Substitute the given values in the formula in (b) above

x = ½(P - 2r - 2πr)

x = ½(660 - 2 * 50 - 2π * 50)

x = ½(660 - 100 - 100π)

x = ½(560 - 100π)

Take π as 3.14

x = ½(560 - 100 * 3.14)

x = ½(560 - 314)

x = ½ * 246

x = 123 feet

Which three lengths cannot be the lengths of the sides of a triangle? (1 point)

Blababa [14]

For three lengths two be able to be the sides of a triangle, the longest side must be less than the sum of the two other sides.

A.
25 is the longest side.
16+10=26
25<26

It is possible.

B.
15 is the longest side.
13+12=25
15<25

It is possible.

C.
18 is the longest side.
5+10=15
18 is NOT less than 15.

It is not possible.

D.
15 is the longest side.
8+8=16
15<16

It is possible.

Therefore, the answer is c.

Hope this helps!
