Answer:
97.6 cm³
Step-by-step explanation:
Volume of plastic object :
Volume of cylinder - volume of cone
From. The diagram. :
Radius, r = diameter /2 = 4/2
Volume of cylinder = pi*r²h
V = 22/7 * 2² * 8 = 100.53096 cm³
Volume of cone = 1/3*pi*r²h
V = 1/3 * 22/7 * 2² * 8
V = 2.9321531 cm³
(100.53096 - 2.9321531) cm³
= 97.598 cm³
= 97.6 cm³
Answer:
Solving the inequality
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality
and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

Adding 2 on both sides

Now, we will divide 3 on both sides

So, we get x < 2
Solving the inequality
we get 
Option D is correct option.
Answer:
slope is -1
Step-by-step explanation:
y1-y2/ x1-x2
= -3 - 7 / 8 - (-2)
= -10/ 10
= -1
Answer:
Maya
Step-by-step explanation:
One equation that represents this statement above me could be: <span>4r + 3 (10-r) = 37.
</span>How? R = Rollercoaster - B = Boat Rides
r + b = 10
37 tickets were spent so..
4*r + 3*b = 37
We just multiplied the number of rides on roller coasters and the boats with the price of both.
Now we have to express boat rides from the first equation:
b = 10-r, and express that in the second equation, now we get:
4r + 3(10-r) = 37, which is the answer.
