Answer:

Step-by-step explanation:

Area of a triangle =1/2×b× h

You can only find the 90° angle opposite the longest side of the triangle.

1/2×(6×6)cm

= 1/2×36cm

Joe is making $485 payments monthly, but the amount gets interest on a yearly basis, not monthly, so the amount that yields interest is 485*12

also, keep in mind, we're assuming is compound interest, as opposed to simple interest

Solve for f. 2+1.25f=10-2.75f2+1.25f=10−2.75f

Ne4ueva [31]

We have to solve for f:
2 + 1.25 f = 10 - 2.75 f
1.25 f + 2.75 f = 10 + 2
4 f = 12
f = 12 : 4
f = 3
Answer: f = 3
