Answer:

B. [tex]A(h) =3h^3 -h[/tex]

Step-by-step explanation:

Given is the figure of a trapezoid with following descriptions.

[tex] b_1=2h^2 +2[/tex]

[tex] b_2 =2h^2 +2+ 2h^2-6=4h^2 - 4[/tex]

[tex] height = h[/tex]

Now, by formula of area of trapezoid, we have:

[tex]A(h) =\frac{1}{2} (b_1+b_2)h[/tex]

[tex]A(h) =\frac{1}{2} (2h^2 +2+4h^2 - 4)h[/tex]

[tex]A(h) =\frac{1}{2} (6h^2 -2)h[/tex]

[tex]A(h) =\frac{1}{2} (6h^3 -2h)[/tex]

[tex]A(h) =\frac{1}{2} \times 2(3h^3 -h)[/tex]

[tex]A(h) =(3h^3 -h)[/tex]

[tex]A(h) =3h^3 -h[/tex]

Answer:

If Andre plans on staying within his budget, he should choose Apartment 1.

Step-by-step explanation:

Apartment 1: $1100 rent + $250 utilities = $1350 Total Monthly

Apartment 2: $1350 rent + $100 utilities = $1450 Total Monthly

Andre can spend up to $1320 on rent & $320 on utilities, totaling at $1640. In this situation, Andre needs to save as much money as possible. Either on one of these apartments stay below the budget for monthly cost, but Apartment 2's rent goes $30 higher than his budget allows. In the end, this makes apartment 1 the best option for rent, utilities, and ultimate cost.

If Andre plans on staying within his budget, he should choose Apartment 1.

Answer:

yes

Step-by-step explanation:

13/8, which you can also write as 1 5/8

the formula for area of a trapezoid is 1/2h•(b+b)

so let's plug in the numbers

1/2h•(70)=525

so divide both sides by 70

1/2h=7.5

now divide both sides by 0.5

h=15

so the area is 150.

Answer:

7.425 pints

Step-by-step explanation:

Given that Tamia uses white and blue paint and 1/4 of the amount is white paint then the fraction of blue paint

= 1 - 1/4

= 3/4

Given that the total quantity of paints is 9.9 pints, the number of blue pints used to paint her bedroom walls

= 3/4 * 9.9

= 29.7/4

= 7.425 pints

Answer:

[tex]V=868.13\ ft^3[/tex]

Step-by-step explanation:

Given that,

The side length of the base of the pyramid, a = 14.1 ft

The height of the pyramid, h = 13.1 ft

We need to find the volume of the pyramid. The formula for the volume of the square base pyramid is given by :

[tex]V=\dfrac{a^2h}{3}[/tex]

Put all the values,

[tex]V=\dfrac{(14.1)^2\times 13.1}{3}\\\\V=868.13\ ft^3[/tex]

So, the volume of the pyramid is equal to [tex]868.13\ ft^3[/tex].

20 estudiantes

Explicación paso a paso:

Dejar :

número de estudiantes que firmaron para el clip = x

Número de estudiantes que firmaron para cortometraje = 3x

En el último minuto ;

Se convierte en cortometraje; 3x - 5 y el clip se convierte en; x + 5

Por eso ; la ecuación se convierte en;

x + 5 = 1/2 (3x - 5)

x + 5 = 1,5 x - 2,5

x - 1,5x = - 2,5 - 5

- 0.5x = - 7.5

x = 7,5 / 0,5

x = 15

Por lo tanto ;

Cortometraje: 1/2 (3x - 5)

1/2 (3 (15) - 5))

1/2 (45 - 5)

1/2 (40)

= 20

Por tanto, hay 20 alumnos en cada actividad.

Answer:

A med - A small = (36 - 16)pi inch^2

= 20 pi inch^2

Step-by-step explanation:

Area of medium pizza = 6^2 pi

Area of small pizza = 4^2 pi

A med = 36 pi inch^2

A small = 16 pi inch^2

A med - A small = (36 - 16)pi inch^2

Given:

The figure of two quadrilaterals.

In [tex]ABCD,AB=18,BC=20,CD=22,AD=24[/tex]

In [tex]EFGH,EF=27,FG=30,GH=34, EH=36[/tex]

To find:

Whether the figures are congruent, similar or neither.

Solution:

Ratio of corresponding sides are:

[tex]\dfrac{AB}{EF}=\dfrac{18}{27}[/tex]

[tex]\dfrac{AB}{EF}=\dfrac{2}{3}[/tex]

Similarly,

[tex]\dfrac{BC}{FG}=\dfrac{20}{30}[/tex]

[tex]\dfrac{BC}{FG}=\dfrac{2}{3}[/tex]

[tex]\dfrac{CD}{GH}=\dfrac{22}{34}[/tex]

[tex]\dfrac{CD}{GH}=\dfrac{11}{17}[/tex]

And,

[tex]\dfrac{AD}{EH}=\dfrac{24}{36}[/tex]

[tex]\dfrac{AD}{EH}=\dfrac{2}{3}[/tex]

Clearly, [tex]\dfrac{AB}{EF}=\dfrac{BC}{FG}=\dfrac{AD}{EH}\neq \dfrac{CD}{GH}[/tex].

All corresponding sides are not proportional.

Therefore, the figures are neither similar nor congruent. Hence, third option is correct.

Answer:

12 miles

Step-by-step explanation:

1/2 inch per 2 miles

3 inches away

3 ÷ 1/2 = 6

6 * 2 = 12

Answer:

y = -2x + 12

Step-by-step explanation:

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

I will use the first point (1, 10) and the last point (5, 2)

Plug in these values:

(2 - 10) / (5 - 1)

Simplify the parentheses.

= (-8) / (4)

Simplify the fraction.

-8/4

= -2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the last point (5, 2). Plug in the x and y values into the x and y of the standard equation.

2 = -2(5) + b

To find b, multiply the slope and the input of x(5)

2 = -10 + b

Now, add 10 to both sides to isolate b.

12 = b

Plug this into your standard equation.

y = -2x + 12

This is your equation.

Check this by plugging in the other point you have not checked yet (1, 10).

y = -2x + 12

10 = -2(1) + 12

10 = -2 + 12

10 = 10

Your equation is correct.

Hope this helps!

Answer:

8 maths tests

Step-by-step explanation:

Given data

We are told that in 1/4 hour that is 0.25hour (15 mins) She grades 1 math test

our aim is to find how many maths test she grade in 3 hours (120min)

Hence

in  15 mins she does 1 grading

in 120 mins she does x

cross multiply

15x= 120

divide both sides by 15

x= 120/15

x= 8 maths test

Hence in 2 hours, she can grade 8 maths tests
