Answer: 346.4

Step-by-step explanation:

The whole triangle ABD is a 30-60-90 right triangle. In 30-60-90 triangles, the smallest side is x, the middle side is x\sqrt{3}, and the largest side/hypotenuse is 2x.

Side AB is the smallest side and therefore x=300. Side BD is the middle side and so we can use x\sqrt{3} and we get BD=300\sqrt{3}=519.615

The question is asking for CD, and we know that CD can be equal to BD minus BC since that would isolate CD

Triangle ABC is also a 30-60-90 triangle but the 300 feet is the middle side in this triangle. So we can do 300=x\sqrt{3} and divide 300 by radical 3 and get that x=173.205

Side BC is the smallest side of this triangle so it would be x and x is 173.205.

Now that we have the whole side BD and the part of it BC. We can subtract BD by BC (519.615-173.205) and we get that CD=346.4

The value of y when x=5
Molodets [167]
D. 35 is the answer. Since we know that 14=2k based on the knowledge given in the first part of the equation, we can solve for K. We learn that K=7. Then, we can substitute K into the second equation: y=(7)(5) which is 35.

A bank loaned out $33,500, part of it at the rate of 12% annual interest, and the rest at 14% annual interest. The total interes
algol13

Answer:

  • $17,500 at 14%
  • $16,000 at 12%

Step-by-step explanation:

Let x represent the amount loaned at 14%. Then the total interest earned is ...

  0.14x +0.12(33,500 -x) = 4,370

  0.02x = 350 . . . . . . . . . . subtract 4020 and simplify

  x = 17500 . . . . . . . . . divide by 0.02

The amount loaned at 12% is $33,500 -17,500 = $16,000.

  $17,500 was loaned at 14%

  $16,000 was loaned at 12%
