Answer:

Step-by-step explanation:

Answer:

yes it can

Step-by-step explanation:

yes

Answer:

No

Step-by-step explanation:

You need to use the Pythagorean Theorem.  This will show you if the ratio between the sides is accurate.

a² + b² = c²

8² + 11² = 13²

64 + 121 = 169

185 ≠ 169

The measurements will not fit in a right triangle.

Answer:

The correct option is;

The data for suitcase 1 have an outlier but the data for suitcase 2 does not

Step-by-step explanation:

Range of a box plot

Interquartile range (IQR) for bot suitcases we have

Here we have for suitcase 1

IQR = Q₃ - Q₁ = 12 - 8 = 4

For suitcase 2

IQR = Q₃ - Q₁ = 18 - 5 = 13

Lower outlier = Q₁ - 1.5×IQR

Higher outlier = Q₃ + 1.5×IQR

For suitcase 1 we have;

Lower outlier = 8 - 1.5×4 = 2 (No lower outlier)

Higher outlier = 12 + 1.5×4 = 18

Hence, whereby the whiskers range from 4 to 30, suitcase 1 has a higher outlier

For suitcase 2 we have;

Lower outlier = 5 - 1.5×13 = -14.5  (No lower outlier)

Higher outlier = 18 + 1.5×13 = 37.5

Hence, whereby the whiskers range from 2 to 20, suitcase 2 has no outlier.

Therefore, the correct option is the data for suitcase 1 have an outlier but the data for suitcase 2 does not.

Answer:A

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

When you graph, you can see that the Line crosses the x at (-3,0) and then passes through the y at (0, 12)

Answer:

D

Step-by-step explanation:

To find the intercepts, set the variable you are not trying to find to 0. Also, in case you don't know, f(x) and y are the same thing here. So on this question, it would be:

X-Intercept:

0=4x+12

-12=4x

-3=x

so x intercept is (-3,0)

Y-Intercept:

y=4(0)+12

y=12

so y intercept is (0,12)

Answer:

(0,2), (1,-3)

Step-by-step explanation:

Answer:

The first point is on the y-axis where you are pointing at (0,2) Plot the next point down 5 and 1 to the right at (1,-3).

Step-by-step explanation:

In slope intercept form, the coefficient x is the slope. That's -5 in this example. The constant is the y-intercept. That's 2 in this example.

For a 4 by 4 cube, he needs 4 rows 4 high for 16 cubes in each row.

The back row is  3 x 4 = 12, so he needs 4 more for the back row,

The 3rd row he has 8, so needs 8 more.

The 2nd row he has 4 so needs 12 more,

The first row he has 2 so will need 14 more.

Total needed: 4 + 8 + 12 + 14 = 38 more cubes.

Answer:

  116 tiles

Step-by-step explanation:

You want to know the number of 6 cm equilateral triangle tiles required to cover 1800 cm².

The area of an equilateral triangle of side s is given by the formula ...

  A = (√3/4)s²

The area of a 6 cm equilateral triangle tile is ...

  A = (√3/4)(6 cm²) = 9√3 cm² ≈ 15.588 cm²

The number of tiles required is the total area divided by the area per tile:

  1800 cm² / (15.588 cm²/tile) ≈ 115.47 tiles

In order to cover 1800 cm², Liz will need 116 triangular tiles.

Answer:

100 tiles

Step-by-step explanation:

Each tile is an equilateral triangle with sides 6 cm in length, so the area of each tile can be found using the formula for the area of a triangle:

[tex]\sf:\implies{A = (b \times h) / 2}[/tex]

where b is the base and h is the height.

Since each side of the triangle is 6 cm, the base and height of the triangle are both 6 cm, so:

[tex]\sf:\implies{A = (b \times h) / 2}[/tex]

[tex]\sf:\implies{A = (6 \times 6) / 2}[/tex]

[tex]\sf:\implies{A =18}[/tex]

So each tile has an area of 18 cm².

To find the number of tiles needed to cover an area of 1800 cm², divide the total area by the area of each tile:

[tex]\sf:\implies{A = 1800 / 18}[/tex]

[tex]\sf:\implies{A = 100}[/tex]

Therefore, Liz needs 100 tiles to cover an area of 1800 cm².

Answer:  [tex]\bold{y=-\dfrac{1}{3}x+6}[/tex]

                [tex]\bold{y=-\dfrac{1}{4}x+\dfrac{25}{4}}[/tex]

Step-by-step explanation:

  x + 3y = 18

- x           -x

        3y = -x + 18

      ÷3     ÷3 ÷3

         y = (-1/3)x + 6

-3x - 12y = -75

+3x           +3x

        -12y = 3x - 75

       ÷-12    ÷-12 ÷-12

           y = (-1/4)x + (25/4)

Answer:

1745 centimeters.

Step-by-step explanation:

The first thing is to pass the kilometers to centimeters, we know 1 km equals 100000 cm, therefore:

1745 km * 100000 cm / 1 = 174500000 cm

Now, when applying the scale, we have that it is 1: 100000, so we apply the scale:

174500000 * 1/100000 = 1745

That is to say that on the map those 1745 kilometers represent 1745 centimeters.

Answer:

18,920.00

Step-by-step explanation:

discount = x

original price = $20,000

discount% = 5.4%

x/20,000 = 5.4/100

x · 100 = 5.4 · 20,000

100x = 108,000

100x/100 = 108,000/100

x = $ 1,080.00

Sale price = original $ - discount $ = final answer

$20,000 - $1,080 = $18,920.00

Answer:1,080

Step-by-step explanation:

20,000 x .54 equals $1,080

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The rate of change is a measure of the slope

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)

m = [tex]\frac{10-9}{33-29}[/tex] = [tex]\frac{1}{4}[/tex] ← rate of change

It makes more sense if you think about it in numerical terms.

Say if there were 10 eggs per carton and there were 5 cartons, what would you do to find the total?

You would multiply them

It is the same in this case

The expression would be n x k

It can be written as just nk though

Answer:

Step-by-step explanation:

A. Model is linear

B. y = -16x - 16

(-3, 32) (-2, 16)

(16-32)/(-2 + 3) = -16/1= -16

y - 32 = -16(x + 3)

y - 32 = -16x - 48

y = -16x - 16

Answer:

C

Step-by-step explanation:

Since the question is asking for surface area and the dimensions are multiplied by 10, the surface area is multiplied by 10^2, or 100. (For area it would be 10^3, or 1000)

The linear equation where y is the price of the number of markers x is as follows:

Let

the price of each marker = y

Therefore,

The price of a box with 10 markers = $7

The price of a box with 24 markers  = $14

(10, 7)(24, 14)

Using linear equation

where

m = slope

b = y-intercept

Therefore,

m = 14 - 7 / 24 - 10

m = 7 / 14

m = 1 / 2

Therefore, let's find b

7 = 1 / 2(10) + b

7 - 5 = b

b = 2

Therefore, the  linear equation where y is the price of the number of markers x is as follows:

Answer:

y = 1/2x+2

Step-by-step explanation:

We have two points ( 10,7) and (24,14)

We need to determine the slope using the slope formula

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

    = ( 14-7)/(24-10)

   = 7/14

   = 1/2

The slope is 1/2

The slope formula is y=mx+b where m is the slope and b is the y intecept

y = 1/2x+b

Using one of the points

7 = 1/2 (10)+b

7 = 5+b

7 -5 =b

2=b

y = 1/2x+2

Answer:

3. From the graph, g(0) = -1.

4. t(x) = 2x + 5

   t(0.5) = 2(0.5) + 5 = 1 + 5 = 6

   g(6) = 0 (from graph)

5. 15 = 2x + 5

    2x = 10

      x = 5

6. g(1) = 0

   t(0) = 5

7. t(1) = 7

   g(7) = -2

Answer:

x = 19° ; Write 19° in the box ( don't forgot ° or answer will be incorrect )

Step-by-step explanation:

If XW ║YZ, we can tell that YW is a transversal, as YW ∩ XW, YX;

By alternate interior angles, ∠ ZYW ≅ ∠ YWX, so that ⇒

m∠ ZYW = m∠ YWX,

m∠ YWX = 2x, ⇒ given m∠ ZYW = 2x

By ∑ of angles in triangle Theorem;

m∠ YXW + m∠ XYM + m∠ YWZ = 180° ⇒ through substitution,

( 3x - 5 ) + 90 + ( 2x ) = 180 ⇒ now apply algebra,

3x - 5 + 90 + 2x = 180 ⇒ combine like terms,

3x + 2x - 5 + 90 = 180 ⇒ add,

5x + 85 = 180 ⇒ subtract 85 from either side of equation,

5x = 95, divide 5 on either side,

x = 19°

Solution; x = 19°
