Answer:
86
Step-by-step explanation:
$19 x 34(4) = 19 x 136,
19 x 136 = $2584,
$2584/.30= 86?
210/10 = 21
7*21=7(20+1)=140+7=147
147 is 70% of 210, as 7/10 of 210 is 147.
The answer is c because the number of tickets (t) times the number of adults is the total cost
Answer:
351.86
Step-by-step explanation:
Answer:
Step-by-step explanation:
when h(t)=0
-4.9 t²+19.6t=0
4.9t(-t+4)=0
either t=0 or t=4
so domain is 0≤t≤4
for range
h(t)=-4.9t²+19.6t
=-4.9(t²-4t+4-4)
=-4.9(t-2)²+19.6
so range is 0≤h≤19.6
