Answer:
28°
Step-by-step explanation:
Angle on the circumference is half the angle at the centre
c = ½(56)
c = 28°
The difference between 10 and 115 is 105.
It takes a car 1 hour and 45 minutes to go 105 miles.
Or, it takes a car 105 minutes to go 105 miles.
The average speed of the car: 1 mile per minute since 105/105 = 1..
Answer:
words per minute!
Step-by-step explanation:
Answer: x = 14 and y = 10
Step-by-step explanation: What we have in the question is a pair of simultaneous equations as follows(
x = y + 4 ———(1)
2x - 3y = -2 ——(2)
Looking at both equations, one of the variables has a coefficient of 1, and as a result of that, we shall use the substitution method.
From equation (1), x = y + 4
Substitute for the value of x in equation (2)
2x - 3y = -2
2(y + 4) - 3y = -2
2y + 8 -3y = -2
-y + 8 = -2
Subtract 8 from both sides of the equation
-y +8 -8 = -2 -8
-y = -10
Divide both sides of the equation by -1
y = 10
Having calculated y, substitute for the value of y into equation (1)
x = y + 4
x = 10 + 4
x = 14
Therefore, x = 14 and y = 10
Answer:
r = 8.12
Step-by-step explanation:
The volume for a cylinder is V=πr^2h therefore,
v = 2279.64
h = 11ft
r = ?
2279.64 = πr^2 * 11
207.24 = πr^2
