FV = PV ( 1 + i ) ^t
FV = $400, PV = $220, i = 3% = 0.03
400 = 220 * ( 1 + 0.03 ) ^t
( 1 + 0.03 ) ^t = 400 : 220 = 1.818181
t = log ( 1.03 ) 1.81818
t = 20
After 20 years his investment will reach at least $400.
Answer:
125°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 8 (octagon), thus
sum = 180° × 6 = 1080°
let x represent one of the equal angles, then
3x + 705 = 1080 ( subtract 705 from both sides )
3x = 375 ( divide both sides by 3 )
x = 125
Thus the size of one equal angle = 125°
Sometimes, for it depends on the triangle. Take a right triangle, for instance. In a right triangle, the hypotenuse is always greater than the two legs. Therefore, you cannot label any side as the base, since the sides are different. In an equilateral triangle, on the other hand, all of the sides and angles are the same. Therefore, no matter which way you turn the triangle, every side is equal. In this sense it doesn't matter which side is labeled as the base. So, it really depends on the kind of triangle you're referring to.
Answer:
It costs more to make 101 because with 100 C<10 but with 101 C>10 i think
Step-by-step explanation:
Answer:
35
Step-by-step explanation:
This is because the formula of triangle is supposed to be h x w x 1/2 which in this situation, h=7 and w=10 which makes 70 yd but you have to do 70 x 1/2 which equals to 35 yd
