A metal pipe is 33 3 /4 inches long. If you cut the pipe into pieces that are each 3 3 /4 inches long, how many total pieces will you have?

Answers

3 3/4 = 15/4

We have to deal with each rod since they are not combined.

24/(15/4) = 24(4/15) = 32/5 = 6 2/5

Answer:

The estimated solution is N = 12.

Step-by-step explanation:

1) Round the equation to [tex]N - 6 = 6[/tex].

2) Get the N on one side, and the values on the other side. To do this, add 6 to both sides. You end up with [tex]N = 12[/tex].

3) N = 12 is therefore the answer.

The nth term of a sequence is 2n2 − 1 The nth term of a different sequence is 40 − n2 Show that there is only one number that is in both of these sequences.

Answers

Answer:

Step-by-step explanation:

nth term of a sequence = 2n² - 1

Therefore, terms of the sequence will be,

1, 7, 17, 31, 49, ........... n terms

nth term of a different sequence = 40 - n²

Therefore, terms of the sequence will be,

39, 36, 31, 24, 15, 4, -9, -24 .......... n terms

Since, there is no negative number in the first sequence,

Therefore, out of 6 positive terms of second sequence only one number (31) is common in both the sequences.

f(3) = 3x² +b For the function, f, defined above, f(4) = 49. What is the value of b?

Answers

Answer: 5.4~

Step-by-step explanation:

For the problem F(3) = 3x^2 +b, you have to first figure out what F(3) is and in this case it is 49, so now you have part of the question solved. Then you start working on the other side of the equation 3x^2 +b = 49, we don't know what x is so lets figure it out, by that you need to do 3x^2, the equals 9. So, so far we have the equation 49 = 9x +b. Now we need to get rid of the x on the 9, having a variable is considered multiplying so you need to divide 9 by 9, but remember what you do to one side you have to do to the other, so now you have to divide 49 by 9 and you get 5.444444444. Now the equation is b=5.4~ meaning that b is around 5.4, I hope this helps.

2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?

Answers

Answer:

The rate of change is the slope

In this case

m=2d+50 is a slope intercept equation.

where m is where the y would be

the 2 which is originally where the slope or (m) would be

the d for the (x)

and 50 for the y intercpet or (b)

#1=2

The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.

Tristan and Evan are employees for a company. Tristan is making a salary of $49,000. Evan is earning a salary that is 29% lower than the salary of Tristan. What salary is Evan earning?

Answers

tristan = $49,000
evan=$34790
you can do this two ways:

Find what is 29% of 49,000:
29/100 x 49,000 = 14,210
Then, minus it from 49,000:
49,000-14,210=34790
Evan earns $34790

The second way to do this is by using a multiplier:

First, minus 29 from 100:
100-29=71
Then, convert it to a multiplier by dividing by 100:
71/100=.71
.71 is now your multiplier, multiply this with 49,000:
49,000x.71=34790

You get the same answer as the first method

Answers

9514 1404 393

Answer:

Step-by-step explanation:

Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.

Trying one of the other points in the one of the remaining equations tells you which equation works.

For example, usint (-1, -4) in the third choice, we get ...

f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)

The correct function is the third choice:

f(x) = -3x^2 +x

The graph that represents the range [tex]-4 \le y \le 3[/tex] is graph (b)

The range of the function is given as:

[tex]-4 \le y \le 3[/tex]

The above inequality can be rewritten as:

Mark often buys lunch at the deli next to his work. Lunch at the deli costs $7.50. Mark sets aside $150 for lunches at the deli at the beginning of the month. Which equation describes how much money, y, Mark has after eating lunch at the deli x times during the month?

Answers

Answer:

y = 150 - 7.50x

Step-by-step explanation:

Given that:

Cost per lunch = 7.50

Amoint budgeted for lunch = $150

The equation which models the amount of money, y Mark has after eating x times at the Deli

Amount left = Amount budgeted for lunch - (cost per lunch * number of lunch eaten)

y = $150 - ($7.50 * x)

y = 150 - 7.50x
