Ivan3 years ago
5 0

Answer:

The formula for the circumference of a circle is C = 2πr or C= πd where r represents length of r and d represent length of diameter. The length of a diameter is 2r which is why C= πd. Using this formula, we know that r= 4cm. Thus, C= 2(4)π = 8π ≈ 25.13 centimeters.

In a college there are 16 times as many students as professors. if together the students and professors number 17000, how many s
Oksana_A [137]
Let the number of professors be x.

Hence, number of students = 16x

Professors + students = 17000

x + 16x = 17000

17x = 17000

x = 1000

Thus,

Number of professors = 1000

Number of students = 1000 * 16 = 16000

Crystal got a job working at the local hardware store making
UkoKoshka [18]

1. She is making 8.76 per hour. Let <em>h </em>be the number of hours she worked, and <em>x </em>be what she earned at the end of the day if each hour gave her 8.76. Your answer is h*8.76=x.

2. If she worked 5 hours and 30 minutes, then we will do 5*8.76=43.8. So if it was <em>30 minutes, </em>then you do 43.8/2=21.9. So  43.8+21.9=65.7, so your answer is 65.7.

Pls help me i dont understand this
poizon [28]

Answer:

Equation: 139 + 3x + (5x - 10) + (10x - 9) + 3x = 540 (not simplified, see below for simplified)

x = 20

Step-by-step explanation:

If the sum of the angles is 540°, then that means you add them up to get 540°.

139 + 3x + (5x - 10) + (10x - 9) + 3x = 540

129 + 8x + (10x - 9) + 3x = 540

120 + 18x + 3x = 540

120 + 21x = 540

21x = 420

x = 20
