Answer:

8580 yards

Step-by-step explanation:

[tex]4 \frac{7}{8}miles \times 1760 \frac{yards}{mile} = 8580yards[/tex]

The total will the friend's paddle combined is 51480 yards.

Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor.

The Great Adventures Canoe and Kayak company offers 3 different options as shown in the table.

This afternoon a group of  6 friends is paddling the Adventure Mid Trip in individual kayaks.

The totals will the friends paddle combined is;

[tex]\rm = 4\dfrac{7}{8} \times 6\\\\=\dfrac{4\times 8+7}{8}\times 6\\\\=\dfrac{32+7}{8} \times 6\\\\ =\dfrac{39}{8} \times 6 \\\\=\dfrac{234}{8}\\\\= 29.25[/tex]

Here 1 mile = 1760 yards

The totals will the friends paddle combined is;

[tex]= 29.25 \times 1760\\\\=51480[/tex]

Hence, The total will the friend's paddle combined is 51480 yards.

Answer:

y=-9/2, x=7

Step-by-step explanation:

You can solve this via substitution. First solve for x in terms of y in one of the equations given. Lets use the first one:

25+4y=x

Now plug 25+4y in for x in the second equation

3(25+4y)-2y=30

75+12y-2y=30

75+10y=30

10y=-45

y=-9/2

Plug this into the first equation:

25-x=-4(-9/2)

25-x=18

x=7

Answer:

8.275

Step-by-step explanation:

8.280 - 8.270 = 0.010

0.010/2 = 0.005

8.270 + 0.005 = 8.275

A triangle is a polygon. The total area of the figure can be represented by 12a, (6a+b), and 2b cm².

A triangle is a polygon with 3 sides and 3 vertices.

Since the area of a single triangle is a cm², and the shape is formed of 12 triangles, therefore, the area of the 12 triangles will be equal to,

[tex]\text{Area of the complete figure} = 12 \times a = 12a\rm \ cm^2[/tex]

Given that the area of the complete dark portion is b cm², therefore, the area of the 6 triangles with a cm² of area each, and the black portion can be written as,

[tex]\text{Area of the complete figure} = (6 \times a)+b = (6a+b)\rm \ cm^2[/tex]

As the dark portion also consists of 6 triangles with an area of a cm² each and the total sum of this dark area is b cm². Also, the light portion consists of 6 triangles with an area of a cm². Therefore, the total area can be written as,

[tex]\text{Total area} = 6a+6a = b+b = 2b\rm\ cm^2[/tex]

Thus, the total area of the figure can be represented by 12a, (6a+b), and 2b cm².

Answer:

[tex]x=\dfrac{1}{2} \pi, \dfrac{3}{2} \pi \quad \textsf{in the interval}\:[0,2 \pi)[/tex]

Step-by-step explanation:

Rewrite the given equation so that it equals zero, using the trig identity:

[tex]\sin(2x)=2\sin(x)\cos(x)[/tex]

[tex]\begin{aligned}\sin(2x) & =2\cos(x)\\\sin(2x)-2\cos(x) & =0\\2\sin(x)\cos(x)-2\cos(x) & =0\\2\cos(x)[sin(x)-1] & =0\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Therefore}:\quad 2\cos(x) & =0\\\cos(x) & =0\\x & =\dfrac{1}{2} \pi \pm 2 \pi n, \dfrac{3}{2} \pi \pm 2 \pi n\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Therefore}:\quad \sin(x)-1 & =0\\\sin(x) & =1\\x & =\dfrac{1}{2} \pi \pm 2 \pi n\end{aligned}[/tex]

[tex]\implies x=\dfrac{1}{2} \pi, \dfrac{3}{2} \pi \quad \textsf{in the interval}\:[0,2 \pi)[/tex]

An equation is formed of two equal expressions. The value of x for which the sin(2x) = 2cos(x) will have solution in the interval [0, 2π) is (π/2) and (3π/2).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation can be rewritten as,

sin(2x) = 2 cos(x)

2 sin(x) cos(x) = 2 cos(x)

2 sin(x) cos(x) - 2 cos(x) = 0

Taking 2cos(x) as common,

2 cos(x) [sin(x) - 1] = 0

Now, the two factors can be written as,

cos(x) = 0

x = (π/2)±2πn, (3π/2)±2πn

sin(x) - 1 = 0

sin(x) = 1

x = (π/2)±2πn

Hence, the value of x for which the sin(2x) = 2cos(x) will have solution in the interval [0, 2π) is (π/2) and (3π/2).

Answer:

x° = 45°

y° = 90°

z° = 45°

Step-by-step explanation:

Angles on a straight line add up to 180°

⇒ z° + 135° = 180°

⇒ z° = 180° - 135°

⇒ z° = 45°

The dashes on the side lengths mean that the sides are of equal length.  Therefore this is an isosceles triangle.  The base angles of an isosceles triangle are equal.

⇒ x° = z°

⇒ x° = 45°

The sum of the interior angles of a triangle is 180°

⇒ x° + y° + z° = 180°

⇒ 45° + y° + 45° = 180°

⇒ y° = 180° - 45° - 45°

⇒ y° = 90°

Answer:

32%

Step-by-step explanation:

In order to find the percent of the cost of the cell phone has Jackie saved,

See below how it's done:

[tex] \dfrac{56}{175} \times 100[/tex]

dividing yields:

[tex] 0.32 \times 100[/tex]

multiplying yields:

[tex]32\%[/tex]

Alternative:

Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.

[tex] \dfrac{56}{175} \times 100 \\ \implies \frac{8}{25} \times 100 \\ \implies 8 \times 4 \\ \implies \boxed{32\%}[/tex]

In conclusion:

Jackie has saved 32% of the cost of the cell phone

The function which is same as the function y = 3cos(2(x +π/2)) -2 is: Option A: y= 3sin(2(x + π/4)) - 2

We can use the fact that:

[tex]\sin(\theta) = \cos(\pi/2 - \theta)\\\sin(\theta + \pi/2) = -\cos(\theta)\\\cos(\theta + \pi/2) = \sin(\theta)[/tex]

to convert the sine to cosine.

(this all positive negative refers to the fact that if you use given angle as input to these functions, then what sign will these functions will evaluate based on in which quadrant does the given angle lies.)

Here, the given function is:

[tex]y= 3\cos(2(x + \pi/2)) - 2[/tex]

The options are:

Checking all the options one by one:

[tex]y= 3\sin(2(x + \pi/4)) - 2\\y= 3\sin (2x + \pi/2) -2\\y = -3\cos(2x) -2\\y = 3\cos(2x + \pi) -2\\y = 3\cos(2(x+ \pi/2)) -2[/tex]

(the last second step was the use of the fact that cos flips its sign after pi radian increment in its input)
Thus, this option is same as the given function.

This option if would be true, then from option 1 and this option, we'd get:
[tex]-3\sin(2(x + \pi/4)) - 2= -3\sin(2(x + \pi/4)) - 2\\2(3\sin(2(x + \pi/4))) = 0\\\sin(2(x + \pi/4) = 0[/tex]

which isn't true for all values of x.

Thus, this option is not same as the given function.

The given function is [tex]y= 3\cos(2(x + \pi/2)) - 2 = 3\cos(2x + \pi) -2 = -3\cos(2x) -2[/tex]

This option's function simplifies as:

[tex]y= 3\cos(2(x + \pi/4)) - 2 = 3\cos(2x + \pi/2) -2 = -3\sin(2x) - 2[/tex]

Thus, this option isn't true since [tex]\sin(2x) \neq \cos(2x)[/tex] always (they are equal for some values of x but not for all).

The given function simplifies to:[tex]y= 3\cos(2(x + \pi/2)) - 2 = 3\cos(2x + \pi) -2 = -3\cos(2x) -2[/tex]

The given option simplifies to:

[tex]y= -3\cos(2(x + \pi/2)) - 2 = -3\cos(2x + \pi ) -2\\y = 3\cos(2x) -2[/tex]

Thus, this function is not same as the given function.

Thus, the function which is same as the function y = 3cos(2(x +π/2)) -2 is: Option A: y= 3sin(2(x + π/4)) - 2

Answer:

3.65 ≤ x < 3.75

Step-by-step explanation:

We are finding the lower and upper bounds:

The lowest possible number that can be rounded to 3.7 is 3.65 as the 5 makes the 6 go next.

The maximum possible number to 2 d.p that will be 3.74 as the 4 keeps it at 3.7.

But someone can say 3.749 is a bigger number that 3.74 that will get rounded to 3.7

Someone else can argue with 3.7499.

So to solve this argumnet we put 3.75 but we don't include it.

Therefore our final answer is :

3.65 ≤ x < 3.75
