Answer:
63
Step-by-step explanation: Let n represent the number. If two third of n = 56, n must be 56 times the reciprocal of 2/3 (3/2) 56 time 3/2 = 84. three quarter of 84 is 84 times 3/4 = 63
To solve this exercise you must follow the proccedure below:
a) Find the maximum height of the tennis ball:
You have that the path of the ball can be represented by h=-16t²<span>+18t+5. Then:
t=-b/2a
t=-18/2(-16)
t=0.562
</span>
h=-16t²+18t+5
h=-16(0.562)²+18(0.562)+5
h=10.06
b) How long will it take to reach the ground?
h=-16t²+18t+5
h=0
-16t²+18t+5=0
You must apply the quadratic equation:
t=(-b±√(b^2-4ac))/2a
a=-16
b=18
c=5
When you substitute the values, you obtain:
t=1.35
Draw a rectangle, shade in 40%, that's roses, the other 60% are daisies.
2/5 of the garden is 8 roses, 1/5 of the garden is 4 flowers, 3/5 is 12 flowers, so if 2/5 is 8 roses, 3/5 is 12 daisies.
8+12=20
There are 20 flowers in total.
