Measuring Volume - Overdue -

Answer:

Step-by-step explanation:

50

Solution:  

The description about the graph is:  

Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.  

Part A:  The relationship between the temperature of the city and the sale of sweaters in the city can be found by drawing the line of best fit.  

If you will draw line through , (12.5,6) and (15,4), it will best represent line of best fit, because most of points on same and opposite side of line are equidistant from each other.

Equation of line passing through two points,[tex](x_{1},y_{1}),(x_{2},y_{2})is, \frac{y-y_{1} }{x-x_{1} } = \frac({y_{2} - y_{1}})({x_{2}-x{1} })[/tex]

Equation of line passing through (12.5,6) and (15,4) is given by

[tex]\frac{y-6}{x-12.5} = \frac{6-4}{12.5-15}[/tex]

[tex]2x-25=-2.5+15[/tex]

[tex]2x+2.5y=40[/tex]

[tex]20x+25y= 400[/tex]

[tex]4x+5y=80[/tex]

Part B: Description of line of best fit  

A line of best is the line which passes through all or some points or only through a single point, which describes the relationship between x and y values of data set. The line passes through (12.5,6), (15,4),and (7,10) that is three points.  

(C) 4 x + 5 y=80  

5 y= - 4 x +80

[tex]y=\frac{-4x}{5}+16[/tex]

Slope [tex]= \frac{-4}{5}[/tex], Y- intercept = 16

Answer:

240

Since the expression is 4x + 40 we just substitute 50 in for x, so the new equation looks like this 4(50) + 40 which gets us 240.

Answer:

9. x = 7

10. x = 12

Step-by-step explanation:

Assume the two lines are parallel.

9. The corresponding angles are congruent.

9x - 3 = 7x + 11

2x = 14

x = 7

10. The alternate interior angles are congruent.

5x - 20 = 2x + 16

3x = 36

x = 12

x= 19/48 i did the math and checked it twice and used a math site so gimme brainly please

Answer:

361$

Step-by-step explanation:

Answer:

$361 is the sale price

Step-by-step explanation:

"Half off" on a $722 gold ring is found by expressing 50% as 0.50 and multiplying $722 by 0.50:  $361 is the sale price.

Answer:

4. 23

4. 206

5. 75 ft

7. 6 sections

8. 6 families

Step-by-step explanation:

4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23

4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206

5. Formula for area of triangle = 1/2 x base x height

So, it's 1/2 x 10 x 15 = 75

7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)

8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.

4.      3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.

X³ - 10. Substitute the X for 6. 6³-10= 216.

5.       I'm not 100% sure but I believe that it is 75. I might be wrong.

6.       6

7.       6

I hope that this helps!

Answer:

125-5x^2

this is the answer

Answer:

-5x^2+125

Step-by-step explanation:

You need to go step-by-step here. I would actually prefer to multiply by 5 at the end, because it's easier that way. (You can multiply the terms in any order you want, though.)

So first, multiply (5-x)(5+x). This is a special product: (a-b)(a+b)=a^2-b^2, so:

(5-x)(5+x)=5^2-x^2=25-x^2

But even if you don't know that special product, you can multiply it out. Rewrite (5-x)(5+x) as 5(5+x)-x(5+x).

 5(5+x)-x(5+x)

=25+5x-(5x+x^2)

=25+5x-5x-x^2

=25+0x-x^2

=25-x^2

As you can see, the result is the same regardless of you get it. Now multiply that by 5 to get 125-5x^2, or in standard form, -5x^2+125.

Hope I could help you!

Answer:

Both -1.5 and -3/2 will be halfway between -2 and -1 on the number line. 3/2 will be halfway between 1 and 2. -4/3 will be between -1.5 and -1.

Answer:

Well I can’t really do anything, the best thing I can tell you is that for each number, look at each option and Plot it from there.

You can turn all these into decimals since the number line is a whole number line and decimals are easier to work with in this situation then fractions. So you would have

-1.5, 1.5, -1.5, and -1.33333...

So -1.5 and -3/2 are the same so thats one plot, that would go between -1 and -2.

1.5 goes between 1 and 2

And -1.333...goes more closer to -1 between -2 and -1

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.
