Answer:

$1.67

Step-by-step explanation:

To find out the price per pound, you need to find the unit price.

15/9 = $1.67/1

Simply divide both numbers by 9.

Answer:

0.946 liter

Step-by-step explanation:

Here, we are told to round 0.946353 to the nearest thousandth.

The nearest thousandth is simply the third value after the decimal point.

Now to successfully round this number, we need to consider the number after this number. If the number is less than 5, then we round it up as zero and add to the thousandth digit.

in the case where the fourth number is higher than or equal to 5, we turn it to 1 and add it to the thousandth number

In the case of this question however, we can see that the number is less than 5, so we can only round to 0 and this does not affect the thousandth digit .

Answer: D, 161.16 square centimeters.

Step-by-step explanation:

The surface area of a cylinder (shape of each steel rod) is given by this formula:

[tex]A = 2\pi rh + 2\pi r^2[/tex], where the first 2*pi*r*h measures the area of the curved surface while the second 2*pi*r^2 measures the area of the two circles on the top and bottom.

We are given the area of the top of one rod, which is 7.07 square centimeters.

We are also given the area of the body of one rod, which is 39.58 square centimeters.

The top of one rod is the shape of a circle, and we know there are two circles on both sides of a cylinder, so the surface area of both circular sides are 7.07.

The total surface area of a cylinder is the body plus both circular ends, so the surface area for this cylinder is:

39.58 + 7.07 + 7.07 = 53.72

There are three cylinders, so multiply this value by three to get the answer, 161.16 square centimeters.

Given:

[tex]4=-2\left(x-3\right)[/tex]

To find:

The error that a student has made while solving the equation.

Solution:

We have,

[tex]4=-2\left(x-3\right)[/tex]

Using distributive property, we get

[tex]4=-2(x)-2(-3)[/tex]

[tex]4=-2x+6[/tex]

Subtract 6 from both sides.

[tex]4-6=-2x+6-6[/tex]

[tex]-2=-2x[/tex]

Divide both sides by -2.

[tex]1=x[/tex]

The value of x is 1.

In step 2, the distributive property is not used properly because when -2 is distributive with -3 then we get 6 instead of -6.

Therefore, the student has made error in step 2.

Answer:

Ans: y = (-1/3)x + 2

Step-by-step explanation:

Perpendicular lines have slopes whose product is -1.  The slope given in

y = 3x - 2

is -3.

The slope of the perpendicular line will be m, and m needs to satisfy the equation

3 * m = -1

Hence m = -1/3.

Our perpendicular line is thus

y = (-1/3)x + b

for some constant b.

We are told that the perpendicular line goes through the point (-9,5).  If so, then the following must hold:

5 = (-1/3)(-9) + b

= 3 + b

b = 2

Ans: y = (-1/3)x + 2

Answer:

1. 20 pounds

2. $11

Step-by-step explanation:

To set this up, you have to use a system of equations. It would look like this, where [tex]p[/tex] is pounds and [tex]t[/tex] is total cost:

UPS: [tex]t=7+0.20p[/tex]

FedEx: [tex]t=5+0.30p[/tex]

In order to solve a system of equations you must either a.) graph it, or b.) set them equal to each other.

If you graph it, the answer is where the two lines intersect.

If you set them equal to each other, solve it.

I will set them equal to each other in this:

[tex]7+0.20p=5+0.30p[/tex]

The first step in a problem like this, where there's the same variable on both sides, is to subtract the smaller variable from both sides. In this case, it is  [tex]0.20x[/tex]. That would turn the equation into:

[tex]7=5+0.10p[/tex]

After that, you must solve it like a regular two-step equation.

Start by subtracting 5 from both sides:

[tex]2=0.10p[/tex]

Now, you must divide both sides by [tex]0.10[/tex].

[tex]\frac{2}{0.10}=\frac{0.10p}{0.10}[/tex]

That would give us:

[tex]20=p[/tex]

This means that in order for the prices to be the same, the package must be 20 pounds.

Now in order to find the total cost, you must plug 20 into one of the equations. It doesn't matter which, since they both equal the same. I will plug it into the FedEx equation:

[tex]t=5+0.30(20)[/tex]

Now you can just use a calculator and solve that or do it by hand. Multiply 0.30 by 20, to get 6, then add 5, which equals 11.

You should get: [tex]t=11[/tex].

This means that the total cost, when the costs are the same for both FedEx and UPS, is $11.

Answer: c(x) = 2.00 + 0.50x

Step-by-step explanation:

Since they already charged her $2.00 leave that alone. They charge her .50 per night, x represents the number of nights she rented the movie. thus the answer is c(x) = 2.00 + 0.50x.

Answer: The line is horizontal

Step-by-step explanation:

The slope of a line can be thought of as 'rise over run. ' When the 'rise' is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it

Given parameters:

Cost of paint per month = $320

Cost of quality plain shirts  = $9 each

Selling price  = $24

Rent per month  = $100

Unknown:

Number of shirts Sam has to sell to break even  = ?

Solution :

 Let the number of shirt sold each month  = y

To break even the cost price per shirt must be equal to the selling price;

   i.e;

      Cost price  = selling price at break even point;

Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent

                  = 320 + 9y + 100

                  = 420 + 9y

Selling price =  24y

To break even;

                      420 + 9y  = 24y

                      420  = j24y - 9y

                      420 = 15y

                          y  = [tex]\frac{420}{15}[/tex]  = 28

To break even, Sam must sell 28 shirts in a month.

Answer:

10x +17y=c (C is the total cost)

Answer:

10x+17y = z

Step-by-step explanation:

You have to multiple 10 by the number of t shirts you have(x)

Then you have to multiply 17 by the number of long sleeve shirts you have (y)

You then have to add 10x and 17y to get your total cost(z)

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The answer is B because if its being reflected its like symmetry horizontally

Sorry if this made no sense :c

Have a good day!  

The correct option is Option D: The figure in Option D is reflection about the dotted horizontal line.

Reflection is the geometrical transformation of the figure about an axis, without changing the size and shape of the image in which every point is at same distance from the axis as in the reflected image.

Here the original image is in the 2nd quadrant.

the reflection axis is horizontal and situated in the 3rd and 4th quadrants.

So by reflecting about that axis without changing the size and shape of the image for which the distance of the original image from the axis will be equal to the distance of the reflected object from the axis.

As original image is in the 2nd quadrant the reflected will be drawn at the 3rd quadrant opposite to the original image.

Checking all the options only in Option B and option D have the reflected image at the 3rd quardant. But in Option B the reflected image is situated on the reflection axis which is against the rule of reflection.

Therefore The correct option is Option D: The figure in Option D is a reflection about the dotted horizontal line.

Given :

Target have apple watches on sale this week for $349 and you get an additional 5% off if you use our red card. Best buy sells them for $389 and you have a coupon for 15% off.

To Find :

How much money would you save by purchasing the watch from the store with the better buy.

Solution :

Selling price at Target :

S.P = $( 349 - 349×0.05)

S.P = $331.55

Selling price at Best buy :

S.P = $( 389 - 389×0.15 )

S.P = $330.65

Amount of price saved = $( 331.55 - 330.65 ) = $0.9 .

Hence, this is the required solution.

Step-by-step explanation:

1.) x + 37 + x + 67 + 90 = 180

combine like terms

2x +194 = 180

subtract 194 both sides

2x = -14

x = -7

2.) 63 + 86 = x

x = 149

Answer:

1. (x+37) + (x+67) + 90° = 180°

=> x + x + 37 + 67 + 90 = 180

=> 2x +194 = 180

=> 2x = 180 –194

=> 2x = –14

=> x = –14/2

=> x = –7

2. [The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. ]

x = 63° + 86°

=> x = 149°
