Pls help I’ll give you 35 points Sina's goal is to exercise a
mean of 45 minutes per
day for one week. She
exercised 35, 40, 37, 42,
45, and 50 minutes for six
days. How many minutes
must she exercise on the
seventh day in order to
reach her goal exactly?

Answers

Answer:

26 minutes

Step-by-step explanation:

Since the mean is the average of all the number, we need to reach a total of 315 minutes for the entire week.

[tex]35+40+37+42+45+50=\\75+40+37+42+45+50=\\115+37+42+45+50=\\152+42+45+50=\\194+45+50=\\239+50=\\289[/tex]

Since 315 - 289 = 26, she needs to exercise for 26 minutes on the 7th day in order to reach her goal.

Answer:

26 minutes

Step-by-step explanation:

Let; x be the minutes exercised on the seventh day .

30 + 40 + 37 + 42 + 45 + 50 + x ÷ 6 = 45

244 + x ÷ 6 = 45

Now; the least common multiple is 6

So; multiplying 6 with both sides.

6 * 244 + x ÷ 6 = 45 *6

244 + x = 270

Making x the subject

x = 270 - 244

x = 26

Therefore Sina must exercise for 26 minutes on the seventh day in order to reach her goal exactly.

Note:

Mean is given by adding of numbers given divided by the number of numbers .

Example.Find the mean of 2,4,3so;we have 3 numbersadding numbers = 2 + 4 + 3÷3 = 9÷3 = 3 therefore the mean is 3 .

So; with your question the mean is already given but left with one digit which is the 26 .Hence,you have to represent it by a variable and equate it to the mean given.with change of subject and further calculation , you will get the result which is the 26 minutes

To take a taxi, it costs $3.00 plus an additional $2.00 per mile traveled. You spend $20 on the taxi. How many miles did you go?

Answers

Answer: 8.5 miles

Step-by-step explanation:

Given information

Base fee = $3.00

Fee per mile = $2.00

Distance = x

Total money spend = $20

Set equation

3 + 2x = 20

Subtract 3 on both sides

3 + 2x - 3 = 20 - 3

2x = 17

Divide 2 on both sides

2x / 2 = 17 / 2

[tex]\boxed{x=8.5}[/tex]

To show that you understood the question you have to multiply 41x18 which gives 738 and then add + 14 from the first row so you can find out how many seats are in total .Hope that helps .

How do you know which direction to move on a number line when adding integers?​

Answers

Step-by-step explanation:

To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.

q = 3.5

Step-by-step explanation:

Start by distributing the 5

-15 = 15q - 50 - 5q

Combine like terms

-15 = 10q - 50

Add 50 to both sides

35 = 10q

Divide by 10 to isolate q

35/10 = q

q = 3.5

Answer:

q=3.5 or 4

Step-by-step explanation:

-15=5(3q-10)-5q

-5=15q-50-5q

-15+50=15q-5q

35=10q

Divide both sides by 10.

35÷10=10q÷10

3.5=q

So I have this equation after solving a question:
-a = 6
So my question is that will the minus at the position of a move to 6 turning it into -6?

Answers

-(-6)=6 because - times - equals a positive, so -6x-1=6
a=-6

Answer: any number or variable adding or subtracting when moved to the other side of the equal sign changes sign. Also you can change all the signs in both sides of the equation. so -a = 6 is the same as a = -6 or -6 = a.

Answers

Answer:

  b = 20/7

Step-by-step explanation:

The slope of the first line can be found by solving for y:

  by = -5x +6 . . . . . . add 6-5x

  y = -5/b +6/b . . . . . divide by b

The slope is -5/b.

The slope of the second line can be found by solving for y:

  7y = 4x +7

  y = 4/7x +1 . . . . . . divide by 7

The slope is 4/7.

For the lines to be perpendicular, the product of these slopes must be -1:

  (-5/b)(4/7) = -1

  -20/(7b) = -1 . . . . simplify

  b = 20/7 . . . . . . . multiply by -b

The lines will be perpendicular when b = 20/7.

Answers

The given pattern is an illustration of a linear equation. The students' equations are:

Dan's: [tex]n = s + 2(s - 1)[/tex].Sally's: [tex]n = 3s - 2[/tex]

Given that:

[tex]n \to[/tex] number of tiles

[tex]s\to[/tex] step number

See attachment for the pattern, that is being analyzed by the students.

Dan

For each step, the number of tower is the same as the step number.

This means that:

[tex]n \to s[/tex]

2 arms contain one less block means: 2 x (s - 1) blocks for both arms.

So, Dan's equation is::

[tex]n = s + 2 \times (s - 1)[/tex]

[tex]n = s + 2(s - 1)[/tex]

Sally

First, we calculate the slope (m) of the table

[tex]m = \frac{n_2 - n_1}{s_2 - s_1}[/tex]

So, we have:

[tex]m = \frac{4-1}{2-1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m =3[/tex]

The equation is then calculated using:

[tex]n = m(s - s_1) + n_1[/tex]

This gives:

[tex]n = 3(s - 1) + 1[/tex]

Open bracket

[tex]n = 3s - 3 +1[/tex]

[tex]n = 3s - 2[/tex]
