Evaluate the function h(t)=11-3t for t=5-n

Answers

Answer 1

Answer:

3n - 4

substitute t = 5 - n into f(t)

f(5 - n) = 11- 3(5 - n) = 11- 15 + 3n = 3n - 4

Answer 2

Answer:

$h(t)=11-3(5-n)$ Substitute $5-n$ to $t$ in this equation

$h(t)=11-15+3n$ Use Distributive property

$h(t)=3n-4$ Combine Like Terms

*(Answer)*= $h(t)=3n-4$

James deposited $575 into a bank account that earned 5.5% simple interest each year.If no money was deposited into or withdrawn from the account, how much money was in the account after 2 1/2 years?

Round your answer to the nearest cent.

Answers

Hi there!
So first we should find what 1% of 575 is. To do that de divide it by 1 and get 5.75. Since he gets 5.5 simple interest per year, we multiply 5.75 by 5.5. We get 31.625. This asks how much after 2 1/2 years, so lets multiply 31.625 by 2.5 and get 79.0625. Then add that amount to 575 and end out with 654.0625. But this question asks us to round to the nearest cent, and after rounding we have 654.06. So, after 2 1/2. years he has $654.06! Hope this helps.

Answer:

654.06

Answer:

$a_(n)=12n-8$

Step-by-step explanation:

We have been given a recurrence relation $a_(n+1)=a_(n)+12$ and the first term of the sequence $a_(1)=4$ .

We can rewrite the given recurrence relation as: $a_(n+1)-a_(n)=12$

We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.

We can therefore, write an explicit formula for nth terms of the sequence as.

$a_(n)=a_(1)+(n-1)d\na_(n)=4+(n-1)(12)\na_(n)=4+12n-12\na_(n)=12n-8\n$

This is the required explicit function rule for the given sequence.

64 divided by 0.4 and explain how you did it please i don't wanna be stuck on this all night

Answers

The quotient of the given division is 160.

The given numbers are 64 and 0.4.

What is the division?

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, 64 divided by 0.4

= 64/0.4

Multiply 10 to both the numerator and denominator, we get

640/4

=160

Therefore, the quotient of the given division is 160.

okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.

so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.

so if you have
64 4
---- / ----
1 10

you would switch the 2nd one so the 10 would be on top.

so that would give you 64*10 over 1*4

which equals 640/4

& when you simplify that you get 160

so that's your answer(:

A newborn baby's weight increased by 50% in one month. If the baby weighed 8 pounds at birth, how much did it weigh one month later? Also can you please explain the process on how to do this, Thanks!4 lb
10 lb
12 lb
16 lb

Answers

Answer:

12 lb

Step-by-step explanation:

The baby weighed 8 pounds at birth which means this was the babys original weight. If the baby's weight increased by 50%, it will be 50% of 8 pounds plus the 8 pounds. The percentage 50% iin fraction form is:

$50/100$

50% of 8 pounds is:

$=(50/100)\cdot{8}=400/100=4$

To get the final weight, we must add 4 to the original weight of 8 pound:

$4+8=12$

It would weigh 12 lbs because 50% of 8 is 4 and 4 + 8 = 12 lbs.

If 25% of the students in elementary algebra courses receive a grade of A, and there are 300 students enrolled in elementary algebra this year, how many students will receive an A.

Answers

Answer:

Total number of students receiving A grade = 75

Step-by-step explanation:

Total number of students enrolled in elementary algebra this year =300

Percentage of students receiving a grade of A = 25%

To find number of students that will receive a grade of A.

Solution:

In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.

Number of students receiving A grade = $25\%\ of\textrm{ Total number of students}$
