3 4/15 ÷ ( 8× 6 3/10 )

Answer:

85/10 = 8.5

11/6 = 1.83333333

Step-by-step explanation:

Step-by-step explanation:

change the ÷ into × flip the number too.

[tex] \frac{85}{10} \div \frac{11}{6} = \frac{85}{10} \times \frac{6}{11} [/tex]

Reduce the fraction with 5

[tex] \frac{85}{10} \times \frac{6}{11} = \frac{17}{2} \times \frac{6}{11} [/tex]

Reduce the numbers with the greatest common factor 2

[tex] \frac{17}{2} \times \frac{6}{11} = \frac{17}{1} \times \frac{3}{11} [/tex]

Just multiply now, To multiply the fractions , multiply the numerators and denominators separately

[tex] \frac{17 \times 3}{1 \times 11} = \frac{51}{11} [/tex]

Solution :

[tex] \frac{51}{11} [/tex]

Answer:

7 to the power of 3/2

Step-by-step explanation:

7 is the same as 7¹ and [tex]\sqrt{7}[/tex] is the same as 7 to the power of 1/2

since the bases are both 7, we keep the base and add the exponents when we multiply with exponents, giving us:

7 to the power of 3/2

Answer:

s=8r/9

Step-by-step explanation:

2r=5s/2-s/4 multiply both sides by 4

8r=10s-s (5s times 4 = 20s and 20s/2=10s) combine like terms

8r=9s divide by 9 to isolate s

8r/9=s

Answer:

slope = -4

Step-by-step explanation:

3y = 9 - 12x

Rearrange the right-hand side:

3y = - 12x + 9

Next, Divide both sides by 3 to isolate y:

[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]

y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.

Therefore, the slope = -4.

Find the height of the triangle using the Pythagoras theorem

Then, use it to calculate the area of the triangle

Answer:

[tex]y = e^{3x}.cos4x.sin2x[/tex]

[tex]=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x[/tex]

[tex]dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx[/tex]

Step-by-step explanation:

The function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives the solution as 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.

Product rule in differentiation states that, for two functions f(x) and g(x),

[tex]\frac{d}{dx}[/tex] [f(x).g(x)] = f(x) . [tex]\frac{d}{dx}[/tex][g(x)] + g(x) . [tex]\frac{d}{dx}[/tex][f(x)]

The question is to differentiate y = [tex]e^3^x[/tex].cos4x.sin2x

We have three functions here.

Let u = [tex]e^3^x[/tex] and v = cos4x.sin2x

[tex]\frac{d}{dx}[/tex] [u . v] = u [tex]\frac{d}{dx}[/tex][v] + v [tex]\frac{d}{dx}[/tex][u]

             = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x [tex]\frac{d}{dx}[/tex] [[tex]e^3^x[/tex] ]

             = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x (3[tex]e^3^x[/tex])

[tex]\frac{d}{dx}[/tex] [u . v] =  [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + 3[tex]e^3^x[/tex]cos4x.sin2x

Let the above equation be equation E.

Again apply the product rule for [tex]\frac{d}{dx}[/tex] [cos4x.sin2x].

Let u' = cos4x and v' = sin2x

[tex]\frac{d}{dx}[/tex] [u'. v'] = u' [tex]\frac{d}{dx}[/tex][v'] + v' [tex]\frac{d}{dx}[/tex][u']

            = cos4x [tex]\frac{d}{dx}[/tex][sin2x] + sin2x [tex]\frac{d}{dx}[/tex][cos4x]

            = cos4x [2cos2x] + sin2x [-4sin4x]

            = 2cos2x.cos4x - 4sin2x.sin4x

Substituting this is equation E, we get,

[tex]\frac{d}{dx}[/tex] [u . v] =  [tex]e^3^x[/tex] [2cos2x.cos4x - 4sin2x.sin4x] + 3[tex]e^3^x[/tex]cos4x.sin2x

             =  2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x

Hence the function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.

Step-by-step explanation:

72 tan gloves and 13 black

Step-by-step explanation:

I am not sure who made the dots on the charts, but they are wrong.

y = 1/2 x + 3

domain means all valid values for x.

range means all valid values for y (the functional results).

x = 0

y = 1/2 × 0 + 3 = 3

x = 1

y = 1/2 × 1 + 3 = 3.5

x = 2

y = 1/2 × 2 + 3 = 4

x = 3

y = 1/2 × 3 + 3 = 4.5

x = 4

y = 1/2 × 4 + 3 = 5

so, the range is 3, 3.5, 4, 4.5, 5

y = x - 6

x = 10

y = 10 - 6 = 4

x = 12

y = 12 - 6 = 6

x = 14

y = 14 - 6 = 8

x = 16

y = 16 - 6 = 10

x = 18

y = 18 - 6 = 12

so, the range is 4, 6, 8, 10, 12

Step-by-step explanation:

The perpendicular bisector of the of the hypotenuse side forms a right

triangle with the hypotenuse and the longer leg of the of the triangle.

The ratio, of the length of the segment cut from the perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, is 1 : 3

Reason:

The given parameters are;

An acute angle of the right triangle = 30°

Let R represent the length of the hypotenuse side, we have;

The length of the longer leg, [tex]L_{ll}[/tex] = R × cos(30°) = [tex]\dfrac{\sqrt{3} }{2} \cdot R[/tex]

The perpendicular bisector forms a right triangle with a leg length = R/2

The length of the hypotenuse formed by the bisector is therefore;[tex]R_{bisector} = \dfrac{\dfrac{R}{2} }{cos(30^{\circ})} = \dfrac{\dfrac{R}{2} }{\dfrac{\sqrt{3} }{2} } = \dfrac{R}{\sqrt{3} }[/tex]

The length, L, of the segment cut by the hypotenuse and the longer leg is therefore;

[tex]L= R_{bisector} \times sin(30^{\circ}) = \dfrac{1}{2} \times \dfrac{R}{\sqrt{3} } = \dfrac{R}{2 \cdot \sqrt{3} }[/tex]

The ratio, of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, r, is therefore;

[tex]r = \dfrac{L}{L_{ll}} = \dfrac{ \dfrac{R}{2 \cdot \sqrt{3} }}{\dfrac{\sqrt{3} }{2} \cdot R} = \dfrac{2 \cdot R}{2 \cdot \sqrt{3} \times \sqrt{3} \times R } = \dfrac{1}{3}[/tex]

The ratio, of the lengths, r = [tex]\dfrac{1}{3}[/tex], therefore, r = 1:3

The average speed of Even between two checkpoints is 9 miles per hour.

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

Running a marathon is Evan. Between two checkpoints, he wants to compute his average speed. He takes 0.75 hours to go to the 3-mile checkpoint and 2 hours to get to the 18-mile milestone.

The average speed is given as,

Average speed = 18 / 2

Average speed = 9 miles per hour

The average speed of Even between two checkpoints is 9 miles per hour.

Answer:  65 degrees

Explanation:

The adjacent angle directly above angle 8 is congruent to the 115 degree angle (due to the corresponding angles theorem). This only works because p || q and q || r, so by the transitive property of parallel lines, we know that p || r.

Since the 115 degree angle and angle 8 pair up to form a straight line, we know that the two angles must add to 180 degrees

115+(angle 8) = 180

angle 8 = 180 - 115

angle 8 = 65 degrees

Answer:

[tex]m[/tex]∠8 = 65°

Step-by-step explanation:

The other side (angle) of 115 is [tex]n[/tex] and [tex]n =[/tex] ∠8

To find [tex]n[/tex] you need to subtract 180 - 115 giving you 65, and since n is angle 8, angle 8 is also 65 since the angles have a state of congruence...
