Places A and B are 100km apart from each other on a highway. A car starts from A and another from B at the same time. If they mo

Mashutka [201]

Answer:

Speed of the first car = x = 35km/hr

Speed of the second car = 25km /hr

Step-by-step explanation:

The calculation of speeds of the cars is given below:-

Assume that the speed of the 1st car which is opening from A = x km/hr

and assume the Speed of the 2nd car which is starting from B

= y km/hr

As we know that

Time = Distance ÷ Speed

So, the distance lies between two places i.e. A and B are

80km d = 80 km

1. now when the car moves in the similar direction

So, the corresponding speed of them = (x + y)km/hr

Time = 8hr

d = 80km

$8 = \frac{80}{(x + y)}\\\\x + y = \frac{80}{8}\\\\x + y = 10 ..... (i)$

2. when two cars moving in the inverse direction,

So, the corressponding speed = (x - y) km / hr

Time = 1 hr 20 minutes

That means

= (1 + 20 ÷ 60) hr

= (80 ÷ 60)

= 4/3 hr

d = 80km

Now

4 ÷ 3 = 80 ÷ (x -y)

x -y = (80 × 3) ÷ 4

x - y = 60 ..... (ii)

Now, we will sum equation 1 and equation 2 we will get

2x = 70

x = 35

now, Put x = 35 in (i) we will get

y = 25

Speed of the first car = x = 35km/hr

Speed of the second car = 25km /hr

On a sunny day, Larry notices that his shadow is 24 inches long. If it is 74 inches from the top of his head to the end of the s

kicyunya [14]

Answer:

70 inches

Step-by-step explanation:

Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).

74 inches is the hypotenuse of the right triangle

use pythagorean theorem: a^2 + b^2 = c^2

let h = Larry's height

h^2 + 24^2 = 74^2

h^2 + 576 = 5476

h^2 = 4900

h = sq rt 4900

h = 70

We want to build a box whose base is square, has no top and will enclose 100 m^3. determine the dimensions of the box that will

stiv31 [10]

Let the height of the box be h and the length of a side of the base be s.
Then there are four sides of area hs and one bottom of area s^2.
The volume of this box is then V=(s^2)(h) = 100 m^3. We want to minimize the surface area. The surface area is A = 4sh+s^2.
We can solve the first equation for h and substitute the result into the second equation, to derive a function s alone. If V=hs^2, then h=V/s^2.
Substituting this into A = sh+s^2, A=s(V/s^2)+s^2.

We must minimize this function. First, simplify it to V/s + s^2. Then differentiate it with respect to s:

dA/ds = -V/s^2+2s.

Set this = to 0 and solve for s: 2s=V/s^2. Mult. both sides by s^2:

2s^3=V. Then s^3 = V/2, and s = cube root of V/2.

The dimensions required for minimum surface area are (cube root of V/2)^2 (area of the base) times h, where h is the height and is equal to V/s^2, or V/[cube root of V/2]^2.
