Answer:
68 sandwiches
Step-by-step explanation:
Given that,
A shop sells 15 sandwiches in 10 minutes.
10 minutes = (10/60) hour = (1/6) hour
In (1/6) hour shop sells 15 sandwiches
In 1 hour = 90 sandwiches
To find, no of sandwiches in 3/4 hours, multiply 3/4 by 90. So,
In 3/4 hour = 
sandwiches
or
≅ 68 sandwiches
So, 68 sandwiches can be made in 3/4 hour.
Answer:
Step-by-step explanation:
1 quart = 32 ounces
therefore 32 ounces is sold for $2.24
Therefore, the cost of one ounce is given bybcost 1 ounce + 2.24/32= $0.07
The store also sells a 59 ounce bottle for $3.54
cost 1 ounce = 3.54/59=$0.06
which is the better buy ? on comparing the cost of both bottles , we find the unit cost of 59 oz bottle is lower for $3.54.
Answer:
t = 2.5 s
Step-by-step explanation:
h(t)=-16t^2 +80t+96
height will be greatest when the derivative (velocity) is zero
h'(t) = v(t) = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32 = 2.5 s
notice that 0 = -32t + 80 is just a version of the kinematic equation
v = u + at
where v is final velocity at the top of the arc or zero
u is the initial upward velocity or 80 ft/s
a is gravity or -32 ft/s²
t is time in seconds
