Answer:

1261.1 revolutions

Step-by-step explanation:

Given

[tex]d = 16in[/tex] --- the diameter

[tex]Distance = 5280ft[/tex]

Required

The number of revolution completer

First, calculate the circumference (c) of the tire

[tex]c = \pi d[/tex]

[tex]c = 3.14 * 16[/tex]

[tex]c = 50.24[/tex]

Let the number of revolutions be n.

The product of n and the circumference equals to the total distance travelled.

So:

[tex]c * n = 5280 ft[/tex]

[tex]50.24in* n = 5280 ft[/tex]

Make n the subject

[tex]n = \frac{5280 ft}{50.24in}[/tex]

Convert feet to inch

[tex]n = \frac{5280 *12in}{50.24in}[/tex]

[tex]n = \frac{63360in}{50.24in}[/tex]

[tex]n = \frac{63360}{50.24}[/tex]

Solve for n

[tex]n = 1261.14649682[/tex]

Approximate

[tex]n = 1261.1[/tex]

Answer:

yes

Step-by-step explanation:

yes it is a parallelogram. As we can see it has opposite parallel sides. Opposite angles are equal. If we add another diagonal, the two diagonals will bisect each other.

Answer:

d:192

Step-by-step explanation:

Answer:

f(2) = -3

f(0) = -5

f(-1) = -6

f(1) = -4

f(8) = 3

f(5) = 0

Step-by-step explanation:

us the f value and substitute for x.

1) f(1)= 1 - 5 = -4

2) f(-1) = -1 -5 = -6

3) f(2) = 2 - 5 = -3

4) f(0) = 0 - 5 = -5

5) f(5) = 5 - 5 = 0

6) f(8) = 8 - 5 = 3

then match the f value with the correct answer

Answer:

C) 3x

Step-by-step explanation:

Perimeter can be defined as side a + side b + side c,

since all sides are x we have

x + x + x = 3x

Answer:

4^2+3^2=x^2

16+9=x^2

25=x^2

X=5

So the answer is 5

The Answer Is Sin(B)=4/5

[tex] \sin( \beta ) = \frac{opposite}{hypotenuse} [/tex]

Meaning, sin(B)=4/5

Answer:

4/5

Step-by-step explanation:

The angle you want to look at is the one given to you with the beta symbol. The trigonometric funtion sin mean opposite/hypotenuse. The side that is opposite is stright across from ∠β which would be 4. The hypothenuse is the largest side of the triangle or the "slanted side of the triangle." With that explanation, the hypotenuse is 5.

Answer:

See below

Step-by-step explanation:

Let's convert the two fractions.

The two categories are now closest to -0.6 and closest to 0.8.

Closest to -0.6 or -3/5: -0.2, -4/5,

Closest to 0.8 or 4/5: 0.6, 2/5

Answer:

[tex]\sqrt{61}[/tex]

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 ) = (4, 1)

d = [tex]\sqrt{(4-(-2))^2+(1-(-4))^2}[/tex]

   = [tex]\sqrt{(4+2)^2+(1+4)^2}[/tex]

    = [tex]\sqrt{6^2+5^2}[/tex]

    = [tex]\sqrt{36+25}[/tex]

    = [tex]\sqrt{61}[/tex]

Answer:

the corect answer for this question is (-x,y)

Answer:

  b. intersects x-axis

Step-by-step explanation:

A zero of the polynomial is where y = 0. The equation y = 0 is the equation of the x-axis, so intersections of the graph of the function with the x-axis are places where the function value is zero.

The number of (distinct real) zeros is equal to the number of points where the graph intersects the x-axis.

_____

Additional comment

When (x -p)^n is a factor of the polynomial, the graph will intersect the x-axis at x=p. The zero is said to have "multiplicity n". For odd values of n, the graph will cross the x-axis (change sign) at x=p. For even values of n, the graph will touch the axis at x=p, but will not cross there.

So, the number of intersections with the x-axis tells the number of distinct real zeros, but does not say anything about their multiplicity. Complex zeros will not cause the graph to touch the x-axis.

Answer:

Area is 288.

To find the area of a shape you have to multiply. 18 x 16 = 288.

Answer:

Hello! Answer: Area = 66

What i did was cut them into triangles and used formula for finding triangles

I did 3.3 x 4 = 13.2 then I divide 2 and get 6.6

Then I multiply by 10 cause thats how many triangles will make up the polygon and get 66

Hope this helps!

Answer: [tex]\dfrac{16d^2}{25}+49e^2-\dfrac{56de}{5}[/tex]

Step-by-step explanation:

Given

The expression is

[tex](\dfrac{4d}{5}-7e)^2[/tex]

Use identity [tex](a-b)^2=a^2+b^2-2ab[/tex]

Apply identity

[tex]\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\left( \dfrac{4d}{5}\right)^2+(7e)^2-2\times \left( \dfrac{4d}{5}\right)(7e)\\\\\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\dfrac{16d^2}{25}+49e^2-\dfrac{56de}{5}[/tex]

Answer:

La ordenada de Q es 7.

Step-by-step explanation:

La ecuación de una recta es:

y = a*x + b

donde a es la pendiente y b es la ordenada al origen.

Para este problema, sabemos que la pendiente es -2

Entonces:

a = -2

y = -2*x + b

También sabemos que esta recta pasa por el punto (5, -1)

Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1

Si reemplazamos esos valores en la ecuación, obtenemos:

-1 = -2*5 + b

-1 = -10 + b

-1 + 10 = b

9 = b

Entonces la ecuación de la recta es:

y = -2*x + 9

Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.

Entonces este punto es Q (1, k)

donde k es la ordenada de este punto.

Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k

Reemplazando eso en la ecuación tenemos:

k = -2*1 + 9 = -2 + 9 = 7

k = 7

La ordenada de Q es 7.

Let the two whole numbers be 2x and 5x

The difference between 2x and 5x is 99. So,

5x-2x=99

3x=99

x=99/3

x=33

Therefore the two numbers are

5x=5*33=165

2x=2*33=66

Answer:

28:71

Step-by-step explanation:

99/7=14.14285714 (make sure to keep that in the calculator) that equals 1 part.

Therefore,

2×14.14...=28 (round up to nearest whole number)

5×14.14..=71 (round up to nearest whole number)
