the answer to this is

<h2><u><em>0.04(30h) is the part.</em></u></h2><h2>please mark brainliest :)</h2>

0.04(30h) is the part. Because 0.04 represents 4%, we know that it should be the tax rate. 30h represents the cost for every hour, so we know that that's not the correct answer.

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) os located at (-2,1). What is the distance fr

Sergio039 [100]

Answer:

The distance from B to B' is 5 units

Step-by-step explanation:

The complete question is

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) and point A' is located at (-2,1). What is the distance from B to B'?

we know that

In a translation the figure maintains its dimensions and internal angles

AA'=BB'=CC'=DD'

The distance BB' is the same that the distance AA'

<em>Find the distance AA'</em>

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

A(1,5),A'(-2,1)

substitute in the formula

$AA'=\sqrt{(1-5)^{2}+(-2-1)^{2}}$

$AA'=\sqrt{(-4)^{2}+(-3)^{2}}$

$AA'=\sqrt{25}$

$AA'=5\ units$

therefore

The distance from B to B' is 5 units

how would you estimate the sum? just like estimate the fractions and then get your estimated answer? Q: 2 1/6 + 3 6/11

denis-greek [22]

I think estimation is terrible. If u want to truly solve it, you just need to get a common denominator on each of the fractions. that means the bottom half of both fractions must be the same in addition or subtraction. so here, the common denominator would be 66. What times 6 = 66? 11. So 1*11/6*11 = 11/66. Then what times 11 = 66? 6. So 6*6/6*11. Your new problem is 2 11/66 + 3 36/66. Now you can just add it up, but the denominators will always stay the same, 66. Your answer would be 5 47/66
