Answer:
$3.45
Step-by-step explanation:
15% of 23 is 3.45
The compound interest formula:
A = P · ( 1 + r/n ) ^(n t)
where: P = $50, r = 0.06, n = 12, n t = 12 · 3 = 36;
A = 50 · ( 1 + 0.06/12) ^(36) =
= 50 · 1.005^(36) = 59.834 ≈ $59.83
He needs 13 cans of paint.
The lateral area is given by the area of 5 rectangles, whose dimensions are 15 by 5:
5(15)(5) = 375
Divide this by 30:
375/30 = 12.5 ≈ 13
Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.
Hope it helped u if yes mark me BRAINLIEST!
