Answer:
Step-by-step explanation:
If we are asked about how fast a car is going, this means we are asked about its velocity , which is defined by the relation between the traveled distance and time :
Where:
is the traveled distance
is the time
Solving the equation with the given information:
Finally:
This is the car's velocity
Answer:
do you know what the number for c is?
Step-by-step explanation:
10 and under= 3
11-15=7
16-20=8
20 and over= 2
Answer:
6 pieces
Step-by-step explanation:
The equation is
4x + 10 = 34
If she had 34 pieces, and kept 10, you can subtract the 10 because she divided the rest of the remaining candy after taking 10.
You now have 24 pieces left to divide, which she does between 4 kids, so you divide it by 4.
The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
(3.5) (14) + 2</span><span>
(3.5)^2
If we simplify this expression, we get:
98</span><span>
+ 24.5</span><span>
If you simplify once more, you get
122.5</span><span>
or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>
or about 384.85<span>
