Answer:

The time taken by fight is 3 hours and 38 minutes.        

Step-by-step explanation:

Given : Roger's flight took off at 9:27 a.m. The flight is scheduled to land at 1:05 p.m. If the flight lands on schedule.

To find : How long is the flight?

Solution :

The flight is scheduled to land at 1:05 p.m.

Roger's flight took off at 9:27 a.m.

Taking the scenario according to clock,

Time taken from 9:30 am to 1:00 pm is 3 hours and 30 minutes.

Flight take off at 9:27 am i.e. 3 minutes more.

Flight reached at 1:05 pm i.e. 5 minutes more.

So, In 30 minutes we have to add 3 min and add 5 minutes.

= 30+3+5=38 minutes

Therefore, The time taken by fight is 3 hours and 38 minutes.

A chemist has a 30% and a 45% acid solution. What amount of each solution should be used to make 500ml of solution with 35% acid
9966 [12]
Not sure is this is right but if the chemist wants to make the solution 35% acidic then he can use all of the 30% acid and 5% of the 45% acid.

Coach Pettaway is buying basketball equipment for his team. He gets a
soldier1979 [14.2K]
First, let’s all acknowledge that whoever comes up with problems like this WANTS kids to hate math...smh

I’m sure there is a prettier way to solve this, but here’s what I did:

8(2.25) + 3(22.50) =
18 + 67.50 = 85.50 per “set” of balls/jerseys
400/85.50 = 4.678 = number of “sets” he can buy. Round down to 4 so we have room for tax.

85.5 x 4 “sets”= $342
Tax on 342 is 0.06 x 342 = 20.52

$342 + 20.52 = $362.52 spent

Basketballs = 4 sets x 8 balls per set= 32
Jerseys = 4 sets x 3 jerseys per set= 12

32 basketballs, 12 jerseys, $362.52 spent

Determine if the following sequence is an Arithmetic Sequence. If it is, what would be the 31st term? NOTE: an=a1+(n-1)d
Ivan
<h3>Key points :-</h3>

᪥ The formula to find the 31st term is : \sf \: a_{n} =  a_{1} + (n - 1) \times d

᪥ In the formula, \sf \: a_{1} represents the first term of the sequence.

᪥ \sf\:n is the number of terms, In our case n is 31.

᪥ \sf\:d is the common difference between the terms, In our case d is 4.

What is the first term in the sequence for which d = -2 and a7 = 3?
AnnZ [28]

Answer:

Final answer is c. 15

Step-by-step explanation:

We need to find about what is the first term in the sequence for which d = -2 and a7 = 3

We will use nth term formula of arithmetic sequence.

a_n=a+\left(n-1\right)d

we have been given a7 that means 7th term is 3

so plug n=7, d=-2 and a_n=3 into above formula

3=a+\left(7-1\right)(-2)

3=a+6(-2)

3=a-12

15=a

Hence final answer is c. 15
