Step 1: Prioblem
Estimate the difference of 765 and 333. Explain your estimate.
Step 2: Concept and Method
Difference mean to subtract the smaller number from larger number.
Therefore,
Step 3: Final answer
= 432
Answer:
138.16 square feet
Step-by-step explanation:
The surface area of the cylinder consists of one rectangle and two circles.
1. The radius of the circle is 4 ft, then the area of the circle is
2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.
Find the circumference:
Hence,
3. The surface area of the cylinder is
Answer: C
Step-by-step explanation:
A scale factor less than one makes it smaller, a scale factor of one does not change size, and a scale factor greater them one makes it bigger.
You drove for half the time at 60mph and the other half the time at 30mph.
To find your average speed, we add 60 and 30 then divide them by two (because you drove at 2 different speeds). 60+30 = 90 and 90/2 = 45 so 45 miles per hour is your average speed.
Note: Velocity implies a direction to the force and there is no direction in this question, just speed. Without direction we cannot use velocity, only speed.
