Answer:
3x=78+x-2
Step-by-step explanation:
Answer:
C. C = 0.75b + 3.78
Step-by-step explanation:
We know that Kalvin sells bottles of water, in which he charges 75 cents for each one, with an additional 3.78 for ice.
Easily enough, we know that 0.75 has to be with a variable, because there is 75 cents being charged "per bottle." Therefore look for an answers that has the expression "0.75b".
This would leave us with "C."
Answer:
401
Step-by-step explanation:
1. Approach
To solve this problem, one first has to think about the given figure in a certain way. In the figure, one can see that it is a circle attached on either side of a rectangle. To find the perimeter of the figure, one has to find the circumference of the circle and then add two sides of the rectangle to the answer
2. Circumference of the circle
The formula to find the circumference of a circle is;
(pi) or (pi)
~ diameter times the value (pi)
Normally to find the circumference of a semicircle, one would have to divide this formula by 2, but since in this case, one has to add two congruent semicircles, so therefore, the effect of dividing the equation by two, only to multiply by two again cancels, and hence, there is no need to divide by 2.
Substitute in the values;
(78)(pi)
~ 245
3. Find the perimeter of the entire object
Now, one has to add the two additional sides of the figure, to the circumferences of the semicircles to get the final answer;
78 + 78 + 245
= 401
Answer: =
Step-by-step explanation:
First, Combine Like Terms:
= 3x^2 + −5x^2 + 4x^2
=(3x^2+ −5x^2 + 4x^2)
=2x^2

If d = rt, Then r = d/t
avg speed = 720/t
