You bought a magazine for $4 and 6 erasers. You spend a total of $52. How much did each eraser cost?

Answer:

Step-by-step explanation:

Each signal unit cubes are 1 cm to each side

the dimensions of the large cube is 4 by 6 by 3      width height and depth

a) volume of the cube   Vol = area of the base times height  

              area of the base = the width times the depth  

              Volume = Base Depth

                            =  Width x Depth x Height

                            =      4 x 3 x 6

                            =       12 x 6

                Vol      =   72 cm ³

b )  the volume of the smaller cuboid has different dimensions    

             the smaller cube is 2 by 2 by 1      width height and depth

          Volume = Base Depth

                            =  Width x Depth x Heigh

                            =    2 x 2 x 1  

 Vol smaller cuboid    =   4

      How many smaller cubes can be made?

            The obvious answer might be to straight up divide the large cube volume by the smaler cuboid volume. That might work IF all of the cuboid dimensions divide evenly into the cube dimensions.

  Number of cuboid  =   Volume of the cube  /  Volume of the cuboid

                                  =             72 / 4

                                  =        18

Check this answer by dividing the dimension of the cube by the cuboid

         4 by 6 by 3

         2 by 2 by 1

      (4/2) by (6/2) by (3/1)

        2    by    3   by     3       = 2 x 3 x 3     =    18

Answer:

23

Step-by-step explanation:

Ryan needs to score a 23 this game because if you add all the numbers together (32 + 26 + 23 + 23) then divide them

(32 + 26 + 23 + 23)/4

You will get 23.

Answer:

23 points

Step-by-step explanation:

Let's first start out by first finding the current mean. We can find this by:

[tex]\frac{32+26+23}{4}=27.[/tex]

So we know that his current average is 27 points per game, and we need the average to be 26. So, to find out the total number of points he scores from his 1st, 2nd, 3rd, and 4th game, we will do:

[tex]26\cdot4=104[/tex]

So if he needs 104 points in total to have an average of 26. So, we would subtract his total number of points from his 1st, 2nd, and 3rd game, from 104. If we do this, we would get:

[tex]104-(32+26+23)=104-81=23[/tex]

So he would need to score 23 points next game to have an average of 26 points.

Answer:

2070 people.

Step-by-step explanation:

We can set up the following proportion:

[tex]\frac{46}{100}=\frac{x}{4500}[/tex]

Then, cross multiply, and you'll get your answer: 2070 people.

Hope this helped!

Answer:

2,070 people

Step-by-step explanation:

46% of 4,500 is 2,070

you can also solve this by doing 4,500 x .46 which will also give you 2,070

Answer:

1 1/12inches

Step-by-step explanation:

Given

Length = 1/6 inches

Width = 3/8 inches

Perimeter of the rectangle = 2 (Length + Width)

substitute

P = 2(1/6 + 3/8)

P = 2(4+9/24)

P=  2(13/24)

P = 26/24

P = 1 2/24

P = 1 1/12inches

hence the perimeter of the triangle is 1 1/12inches

Answer:

249.86 ft^2

Step-by-step explanation:

12.4 ft × 9.3 ft ÷ 2 = 57.66 sq ft(for triangle)

57.66+(12.4 ft×15.5 ft) = 249.86 sq ft

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (6, 11)

d = [tex]\sqrt{(6+2)^2+(11+4)^2}[/tex]

   = [tex]\sqrt{8^2+15^2}[/tex]

Angles 2 and 5

Step-by-step explanation:

The first choice is wrong because they are not equivalent to each other

Answer:

Yes

Step-by-step explanation:

I see no mathematical reason this could not happen. It has three sides which is what makes a triangle.

Answer:

A = 18 cm²

Step-by-step explanation:

The volume (V) of a prism is calculated as

V = area of base (A) × height

Here V = 216 cm³ and h = 12 cm , then

A × 12 = 216 ( divide both sides by 12 )

A = 18 cm² ← area of base

Answer:

Step-by-step explanation:

If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so

5x-15=3x+1

2x-15=1

2x=16

x=8 degrees.

The angles are

a=5x-15, and x=8 so

a=5(8)-15

a=40-15

a=25 degrees.

Answer: 9

Step-by-step explanation:

12 + 8 + 7 + 12 + 6 = 45

There are 5 numbers

45 / 5 = 9

Answer:

mean = 9

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] , then

mean = [tex]\frac{12+8+7+12+6}{5}[/tex] = [tex]\frac{45}{5}[/tex] = 9

Answer:

Assuming the question is: How many students are performing:

There are 45 students. The number of students performing is 3/5 of this total number of students.

This number is actual figures is:

= 3/5 * 45

= 27 students

The number of students in the backstage crew is therefore:

= 45 - 27

= 18 students

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

   4y = 3x - 18    <------------------  FINAL ANSWER
