Well, 4 + 6 + 9 = 19, so $14 is a reasonable answer. If we have $19 assuming that each flower costs $1, then if the estimate is $14, that means that each flower is less than $1, which makes sense. Assuming that all of the flowers cost the same, then each flower would be about 74 cents. This would make sense considering that you are buying tulips, roses, and carnations. I really hope this helps; if not, good luck on your homework.

Andrew is painting a wall on the side of his house. He has a 20 foot ladder wich makes a 79 degree angle with the ground. Standi

Andrew can reach a maximum of 24.6ft high up the wall.

The right-angled triangle formed can be solved using the sine ratio. that is

sin(72^\circ})=\dfrac{h}{20}

where h is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for h, we get

0.9816=\dfrac{h}{20}\\\\h=20\times0.9816\\\\h=19.632ft

Since Andrew can reach an extra 5ft above the point where the ladder rests against the wall, the maximum height Andrew can paint is

(19.632+5)ft=24.632ft\\\\\approx24.6ft
