First, we solve to find out what percent of the population has brown eyes and black hair. There are 303 people total, and 64 people with the description. After dividing, we find that about 21% of people have black hair and brown eyes.
Next, we use the chart to see that 9 out of the total 303 people have black hair and blue eyes. We divide this and see that this is only about 3%.
Last, we subtract 3 from 21 and get 18%
So, the answer is 18%

9/303 = 0.0297029703 or 3%

64/303 = 0.2112211221 or 21%

21% - 3% = 18% as the answer.

D (t)=16t□2+96t+112 where t represents time in seconds
Luda [366]
A.
the starting point is where t=0
d(0)=-16(0)^2+96(0)+112
D(0)=112
started from 112 feet


b. max height is vertex
for
y=ax^2+bx+c
the x value of the vertex is -b/2a

so
D(t)=-16t^2+96t+112
t value of vertex is -96/(2*-16)=3
it reaches after 3 seconds

C. simpliy evaluate D(t) for t=3
D(3)=-16(3)^2+96(3)+112
D(3)=-16(9)+288+112
D(3)=-144+400
D(3)=256
max height is 256ft

Please help explain each problem thank you have a great day
boyakko [2]
Part A. 250+45a=t
That's because 'a' is the variable in which we don't know how many appointments she will have. 'a' times the $45 would be in the equation. Then you would have to add the $250 for the tests and medicines.So 250+45a=t
Part B.(250+45a)-(25%*t).
That's because the first set in parentheses is the total cost. You would have to subtract that buy the discount times the total cost which represents the the second set of the equation.:)
Part C.25%*6 appointments equals 1.5. You have to solve (250+45) and then multiply 25%*6.That product plus (250+45) would be your final answer.U won't tell you the answer because it would help.U would need explanation.This is how I would answer the question.Hope this helped

ra1l [238]

Answer:

her profit is $25

Step-by-step explanation:

Given that

She spends $15 for purchasing fabric so that she make the baby blankets

And, she can make 4 blankets from one piece of fabric

Now she sold the blankets for 10 each

So we need to find out the profit

As we know that

Profit = Selling cost - purchasing cost

= (4 × $10) - $15

= 40 - $$5

= $25

hence, her profit is $25
