Answer:

The polygons are similar.

Step-by-step explanation:

By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.

Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.

The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is \frac{3}{3.75}.

The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is \frac{5}{6.25}.

If these polygons are similar, these proportions must be equal.

\frac{3}{3.75}=\frac{5}{6.25},\\0.8=0.8\:\checkmark

Checking, we see that these proportions are equal, and therefore the polygons are similar.

Yes because say we are doing 2/10 if you divide 2 by 2 and 10 by 2 it will be 1/5 which equals the first one so yes they are.

If a line crosses the y-axis at (0,1) and has a slope of 4/5, what is the equation of the line ?
stepladder [879]
The slope intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We are given that the slope is 4/5 and the point (0,1) so we know m=4/5 and b=1 so:

y=4x/5+1  now to rearrange into standard form ax+by=c

y=(4x+5)/5

5y=4x+5

5y-4x=5

So the answer is D.

However, by convention, in standard form, the equation is usually expressed with a positive coefficient for x.

5y-4x=5 SHOULD be expresses so the x has a positive coefficient, divide both sides by -1 and you have the technically correct form:

4x-5y=-5

Apparently whomever/whatever posed this question to you was unaware of this convention :P

A dealer bought an article for $7 sold it for $8 bought it back for $9 and then sold it for $10 how much profit did he make
Anit [1.1K]
To the total amount of money that a dealer spent is $7 + $9 or %16. His revenue from selling the same articles is $8 + $10 which is equal to $18. The profit is the difference between the total revenue and total cost. 
                              profit = $18 - $16 = $2
Thus, the dealer has a profit of $2.
