V=whl=14·13·19=3458m³

Answer:

1152.66 m³

Step-by-step explanation:

Volume = ⅓ × base area × height

= ⅓ × (length × width) × height

= ⅓ × 19 × 14 × 13

= ⅓ × 3458

= 1152.66 m³

Answer:

x= - 4

Step-by-step explanation:

2 * x^2 + 8 * x = x^2 - 16

2 * x^2 - x^2 + 8 * x + 16 = 0

x^2 + 8 * x + 16 = 0

(x + 4) * (x + 4) = 0

x = - 4

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

where:

m is the slope or rate of change

b is the intercept

Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the rate change(slope)

Slope = 20000-5000/9-3

Slope = 15000/6 = 2500

Determine the y-intercept by substituting

5000 = 2500(3) + b

b = 5000 - 7500

b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

Hey ! there

Answer:

Step-by-step explanation:

In this question we are provided with an equation that is 5 ( 3x - 1 ) = 55 and we are asked to find the value of 2x - 2 .

Firstly , we need to find the value of x . So we need to solve the equation .

SOLUTION : -

[tex] \quad \longmapsto \qquad \: 5(3x - 1) = 55[/tex]

Step 1 : Dividing with 5 on both sides :

[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{5}(3x - 1)}{ \cancel{5}} = \cancel{\dfrac{55}{5} }[/tex]

On cancelling , We get :

[tex] \quad \longmapsto \qquad \:3x - 1 = 11[/tex]

Step 2 : Adding 1 on both sides :

[tex] \quad \longmapsto \qquad \:3x - \cancel{1} + \cancel{1} = 11 + 1[/tex]

On simplifying , We get :

[tex] \quad \longmapsto \qquad \:3x = 12[/tex]

Step 3 : Dividing with 3 on both sides :

[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{3}x}{ \cancel{3}} = \cancel{ \dfrac{12}{3} }[/tex]

We get ,

[tex] \quad \longmapsto \qquad \: \underline{\boxed{\frak{x = 4}}}[/tex]

→ Therefore , value of x is 4 .

Verifying : -

Now we are verifying whether our answer is wrong or right . So ,

Therefore , our value of x is correct/valid .

We need to find the value of 2x - 2 .

[tex] \quad \longmapsto \qquad \:2x - 2[/tex]

So substituting value of x in it :

[tex]\quad \longmapsto \qquad \:2( \bold{4}) - 2[/tex]

Multiplying 2 with 4 :

[tex]\quad \longmapsto \qquad \:8 - 2[/tex]

Subtracting 2 from 8 :

[tex]\quad \longmapsto \qquad \: \blue{\underline{\boxed{\frak{6}}}} \quad \: \bigstar[/tex]

Indigo drinks 5 ounces glasses per hour.

A fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole.

As in [tex]\frac{4}{5}[/tex]  hour she drinks =10*[tex]\frac{2}{5}[/tex]

                                     = [tex]\frac{20}{5}[/tex]

                                     =4 ounce

She is drinking 4 ounce in [tex]\frac{4}{5}[/tex]  hours,

= [tex]\frac{4}{\frac{4}{5} }[/tex]

= [tex]4*\frac{5}{4}[/tex]

=5 ounce in an hour.

Step-by-step explanation:

area of the square :

6×6 = 36 cm²

area of the triangle :

6×4/2 = 6×2 = 12 cm²

height of triangle :

area of the triangle is

10×height/2 = 40

10×height = 80

height = 80/10 = 8 cm

width of the logo :

the central square has ashtray an area of 5×5 = 25 cm².

that leaves us 125 - 25 = 100 cm² for the 4 triangles.

I assume all 4 triangles are equal, so each has an area of 100/4 = 25 cm².

the area of such a triangle is

baseline × height / 2.

so, in our case

5 × height / 2 = 25

5 × height = 50

height = 10 cm

and so, the width of the logo is 2 times the height of these side triangles, and 1 time the side length of the central square :

2×10 + 5 = 25 cm

area of a square = s²

s² = 196

s = √196

therefore s = 14cm

Answer: 15x+30

Step-by-step explanation:

The value of 5(3x+6) is 15x+30

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that;

Answer:

(-2, 3)

Step-by-step explanation:

The function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Cost for the unit = $329.99

Annual operating cost = $108.78

C(n) represents the cost per year

n represents the number of years

The function can be modelled:

C(n) = (329.99 + 108.78n)/n

Thus, the function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.
