To estimate, round first then do the math. If you round 5,397 to 5400 and 62 rounds to 60, then 5400÷60 = 90.
90 is the BEST estimate.

Answer:
a=5
b=15
Step-by-step explanation:
By following the pattern on the table we can see that the x is increasing by 1 and the y is increasing by 3 each time. Therefore, the next set of numbers would be (5,15).
Answer:
a ) Surface Area ⇒ 222 cm^2, Volume ⇒ 180 cm^3
b ) Surface Area ⇒ 372 cm^2, Volume ⇒ 360 cm^3
c ) Surface Area Increase ⇒ ( About ) 67.56 %, Volume Increase ⇒ 100 %
Step-by-step explanation:
a ) Consider dividing the figure into parts, first solving for the area of the base, using the attachment below for guidance;
As you can see, in the picture I have made it so that the base is nested in a rectangle with dimensions 8 by 5. Calculating the area of this rectangle, subtracting the area of a square with dimensions 2 by 2 cm, we can derive the area of the base in a much quicker manner;
Now let us imagine adding the another dimensions to this two dimensional base. That would make a 3 - d prism, with surface area equivalent to mini rectangles and squares with a common dimension being the length of the height; 5 cm
b ) We have calculated the area of the base before, now let us solve for all the " mini shapes " given a new height of 10 cm;
c ) <em>Solution; Increase of Surface Area ⇒ ( About ) 67.56 %, Increase of Volume ⇒ 100 %</em>
Answer:
Step-by-step explanation:
A+B+C=180
2x+x+90=180 ( the 90 comes from the right angle in the given triangle)
3x=90
x=30°
:) these are all kinda the same strategy.. notice?
