The answer is 6.5km a minute

Why? I made proportions. 80km/10mins and 100km/20mins and then simplified to 8km/1 min and 5km/1min and then I found the average by adding 8+5 (making 13) and then dividing 13 by 2 which would be 6.5. 6.5km a minute.

Last month, Grayson and Justine sold candy to raise money for their debate team. Justine sold 1 1/5 times as much candy as Grays
ale4655 [162]

Answer: 4/5 of a box of candy

Step-by-step explanation:

Justine sold 1¹/₅ times the ²/₃ of a box of candy that Grayson sold.

Justin sold;

= 1¹/₅ * ²/₃

= 6/5 * 2/3

= 12/15

= 4/5 of a box of candy

please just give me the answer is homework please help1)vertex 2)axis of symmetry 3)x-intercepts 4)maximum or minimum 5)max/min
aniked [119]

Answer:

See explanations below

Explanation:

Vertex of a graph is the lowest point on the curve. The vertex occurs at (1.75, -2.5)

The axis of symmetry is the point on the x axis of the line that cuts through the minimum point. The axis of symmetry occurs at x = 1.75

x intercept is the point where the curve cuts the x axis. The x intercept occurs at x = 0 and x = 2.5

To get the minimum, we will use the formula;

c - b^2/4a

The equation of the curve is expressed as;

(x-0)(x-2.5)

= x (x-2.5)

= x^2 - 2.5x

a = 1, b = -2.5, c = 0

minimum = 0 - (-2.5)^2/4(1)

minimum = -6.25/4

minimum = -1.5625

Minimum value occurs at the base of the parabola. The minimum value of the function is -2.5

y intercept is the point where the curve cuts the y axis. The y-intercept occurs at y = 0.

Please help me!!!!! :)

To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:

{height }^{2}  = {13}^{2}  -  {10}^{2}  \\ {height }^{2}  = 69 \\ height =   \sqrt{69}

We can then use the pyramid formula to find the volume:
base \:  \times  \: height \:  \times  \frac{1}{3}

In this case,the volume will be:

10×_/69×1/3
=27.68874...
≈27.7 units^3

Hope it helps!

1/R = 1/A + 1/B assuming that all denominators are non-zero solve for B
Rashid [163]

Answer:

1/B = 1/R - 1/A

B/R - B/A = 1

B - BR/A = 1

B = 1 + BR/A
