Answer:
Step-by-step explanation:
This is really super super simple as long as you know the rules for finding a perpedicular slope from a given line. The perpendicular slope of a line is the opposite reciprocal of the given slope. Our given slope is 3/5, therefore, the perpendicular slope is -5/3. There's only one line with that exact slope, so the choice is the last one. (BTW, check the coordinate you gave. It should be
(15, -5), not (15, 5)!)
Answer:
area = 105 hm2
Step-by-step explanation:
area = (base1 + base2) * heigth / 2= (14 +16)*7 / 2 = 105 hm2
Answer:
Step-by-step explanation:
We have 
23 x 36 mod 5 = 3 (since unit digit is 8)
23x36 mod 11 =3
Since 5 and 11 are prime we get
23x36 mod 55 = 3 mod 55

b) 91 = 13 x7
29x51 mod 91 =23
Answer:
Let D represent the average rate of change between 1990 and 1999
D ≈ 33%
Step-by-step explanation:
412+412×(Ｄ÷100 )= 549
⇔ 412×(Ｄ÷100) = 549 - 412
⇔ 412×(Ｄ÷100) = 137
⇔ Ｄ÷100 = 137÷412
⇔ Ｄ÷100 = 0.332524271845
⇔ D = 33.2524271845.
