Answer:
area= 78.5 cm²
circumference= 31.4 cm
Step-by-step explanation:
Given that the radius is 5cm, r= 5. Substitute r= 5 and π as 3.14 into the equation:
Area of circle
= 3.14(5²)
= 78.5 cm²
Circumference of circle
= 2(3.14)(5)
= 31.4 cm

Answer:
There are 144 faculty at the college are certified
Step-by-step explanation:
- A local community college employs 240 full time faculty
∴ There are 240 full time employs
- Approximately 3/5 of the full time faculty are certified to teach online
∴ 3/5 of the total 240 are certified to teach on line
- We need to find how many faculty at the college are certified
<em>To find that multiply the fraction of the certified by the total number </em>
<em>of the full time faculty</em>
∵ The fraction of certified is 3/5
∵ The total of the full time faculty is 240
∴ The number of certified = × 240
∴ The number of certified = 144
<em>There are 144 faculty at the college are certified</em>
Answer:
y = 0.1x - 4
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-3, 7)
Points on the y-axis (y1, y2) = (-7, -6)
First of all, we would find the slope;
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope = (-6 - (-7))/(7 - (-3))
Slope = (-6 + 7)/(7 + 3)
Slope = 1/10
Slope = 0.1
Next, we would write the equation using the formula;
y - y1 = m(x - x1)
y - (-7) = 0.1(x - (-3))
y + 7 = 0.1(x + 3)
y + 7 = 0.1x + 3
y = 0.1x + 3 - 7
y = 0.1x - 4
