Answer:
6.81m
Step-by-step explanation:
Using the formula for finding the length of am arc
L = theta/360° × 2πr
theta is the angle subtended by the drum in rotation
r is the radius of the drum
Given theta = 315.7°
r = 1.1m
Substituting the given values into the formula we have:
L = 315.7/360 × 2π(1.1)
L = 315.7/360 × 2.2π
L = 315.7/360 × 2.2(3.14)
L = 315.7/360 × 6.91
L = 6.81metres
Line of about 6.81metres will be wounded around the drum
Answer:
c. 0.6
Step-by-step explanation:
A student cannot receive an A or a B simultaneously, so .
Grade of A equals .30 and the probability of receiving a grade of B equals .30.
This means that
The probability that a randomly selected student from this class will receive either an A or a B equals:
This is:
So the probability is 0.6, and the correct answer is given by option c.
Answer:
y = -9/8x +7
Step-by-step explanation:
We know two points on the line so we can find the slope
m = ( y2-y1)/(x2-x1)
m = ( -2 -7)/(8 -0)
= -9/8
We also know the y intercept which is 7
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -9/8x +7
Answer:
9y +6 +8y
