Lorico [155]
The amount avaliable for division into lots is
  25 ac - 0.35*25 ac = 0.65*25 ac = 16.25 ac
There are 43,560 ft² in an acre, so the number of possible lots is
  (16.25 ac)*(43,560 ft²/ac)/(25,000 ft²/lot) = 28.314 lots

The developer has enough area for 28 lots.

If 3/7 of Z is 42, what is 5/7 of Z?
Anastasy [175]

Answer:

x = 70

Step-by-step explanation:

First to make the equation easy, divide 42 by 3 to get what 1/7 of Z equals.

42 / 3 = 14

Now to get 5/7 of Z, just multiply 14 by 5.

14 x 5 = 70

x = 70

Hope this helped.

If line AD is a tangent to circle B at point C, and m∠ABC = 55º, what is the measure of ∠BAD?
4vir4ik [10]
The tangent AD at point C forms a right angle to circle B, such as ∠ACB=90° and ∠ABC=55°.

We also know that the summation of all angles in a triangle is 180°. Thus we have the expression below:
180°=∠ABC + ∠ACB + ∠BAD
180°=55°+90°+∠BAD
∠BAD=35°

Therefore, the answer is 35°.
