Answer:
351.9 cm^3
Step-by-step explanation:
d = diameter = 8 cm
r = radius = diameter/2 = 4 cm
h = height = 7 cm
volume = (pi)r^2h
volume = (3.14159)(4 cm)^2(7 cm)
volume = 3.14159(16 cm^2)(7 cm)
volume = 351.858 cm^3
Answer: 351.9 cm^3
10 for red and blue together and 5 for green and yellow together
Answer:
70 members in 2016
Step-by-step explanation:
In 2016
Let the number of members= x
They all paid y amount
Total fees= 42
Xy= 42...... equation 1
In 2017
Members= x+20
They paid y-0.1
Total fees = 45
(X+20)(y-0.1)= 45…equation 2
Xy -0.1x +20y -2= 45
Using values from equation 1
42-0.1(42/y) +20y -2= 45
-4.2/y+20y-5= 0
20y² -4.2 -5y = 0
100y² -25y -21= 0
Solving quadratically
Y= 0.6 or -0.35
We are dealing with price so y Is
definitely a positive number
Y= 0.6
If y= 0.6
Solving for x
Xy= 42
X= 42/0.6
X=70
There were exactly 70 members in 2016
I believe it is 2.7 hours.because 25.5 miles is equal to about 41 kilometers and 110 kilometers and hour divided by 41 kilometers is 2.68 rounding to 2.7
Answer:
(3,0)
Step-by-step explanation:
to find the x-intercept, you have to plug in 0 for y to solve for x. this would be -6x-2(0)=-18. this simplifies to -6x=-18. we can divide by -6 on both sides. this results in x=3. this is the value of the x-coordinate, so the answer is (3,0) since the x-intercept is where the line crosses/touches the x-axis.
