Answer:

  48 kph

Step-by-step explanation:

The distance is immaterial, as long as it is the same at both speeds. The total time for some distance d is ...

  t = d/40 +d/60

And the average speed is ...

  2d/t = 2d/(d(1/40 +1/60) = 2/(1/40 +1/60) = 2(40)(60)/(40+60) = 4800/100 = 48

The average rate for the round trip is 48 kph.

_____

Additional comment

This value is called the harmonic mean of the two speeds. It is the reciprocal of the average of the reciprocals of the speeds.

[tex]-1/2[/tex]

Step-by-step explanation:

[tex]-1/2[/tex] is the answer because [tex]-1/2[/tex] is the gradient of the line in the slope. 3 is the y inter. Which is where the line goes over the y-axis.

Answer:

7.79

Step-by-step explanation:

19 percent of 41 is the same as 19 per hundred of 41. We can therefore make the following equation:

19/100 = X/41

To solve the equation above for X, you first switch the sides to get the X on the left side, then multiply each side by 41, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

19/100 = X/41

X/41 = 19/100

X*41/41 = 19*41/100

X = 779/100

X = 7.79

The work above shows the long way to explain how to calculate 19 percent of 41 in order to give you a foundation and better understanding of how to calculate the percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 19 percent of 41?", Y is 41 and P is 19:

(41 * 19)/100 = 7.79

And once again you see that the answer is 7.79.

Answer:

[tex]y = {(x + 3)}^{2} - 14[/tex]

Step-by-step explanation:

The original equation

[tex] f(x) = {x }^{2} + 6x - 5[/tex]

vertex form

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

solve for the x coordinate of the vertex, h

[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]

substitute -3 back into the original equation to solve for y

[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]

substitute h and k values into the vertex form

a = 1 So we can omit it

[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]

Answer:

13

Step-by-step explanation:

So the concept is that co-interior angles add up to 180 in parallel line. This means:

3x + 9 + 9x + 15 = 180

So we solve for x.

12x + 24 = 180 ( What I did was simplifying the equation).

12x + 24 - 24 = 180 - 24

12x / 12= 156 / 12

x = 13

Answer:

6. [tex]\pi = \frac{C}{2r}[/tex]

7. Translation

Step-by-step explanation:

6: To solve for π means to isolate it on one side.

Step 1: Divide both sides by 2r.

Therefore, π = circumference over twice the radius, or circumference over diameter.

7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant

Therefore, this is a translation.

Answer:  π = c/d

Step-by-step explanation: srry if its wrong im not well at math

The perimeter of a shape is the sum of its side lengths.

Joshua miscalculated the third length of the triangle

First, we calculate the third length (x) of the triangle.

Because the triangle is right-angled, we can make use of Pythagoras.

So we have:

[tex]x^2 = 7^2 + 7^2[/tex]

[tex]x^2 = 2(7^2)[/tex]

Take square roots of both sides

[tex]x = \sqrt{2(7^2)[/tex]

[tex]x = 7\sqrt{2[/tex]

The other shape in the figure is a square.

So, the perimeter (P) is

[tex]P = 7 + x + x + x + 7[/tex] ---- i.e. the sum of the visible lengths

So, we have:

[tex]P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7[/tex]

Evaluate like terms:

[tex]P = 14 + 21\sqrt2[/tex]

Hence, Joshua's error is that:

He miscalculated the third length of the triangle

Step-by-step explanation:

since the function is

[tex]f(x) = - \frac{2}{30} x + 2[/tex]

The y-intercept is 2 and the x-intercept is 30.

since the treadmill is counting down the slope of the function would be negative. she set the treadmill for 2 minute walk so at 0 minutes she has 2 minutes left. as the treadmill counts down at the 30-minute mark she will have zero minutes left.

$513.75

Step-by-step explanation:

Let h represent the number of hours he worked in a week

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

Hence, his pay Is represented by equation:

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Therefore, he earns $513.75
