For the first 30 km, the bicyclist rode with a speed of v km/hour. For the remaining 17 km he rode with a speed which was 2 km/h
damaskus [11]

Answer:

t= 2.52 hours

Step-by-step explanation:

It is given that for first 30 km, the speed of bicyclist is v km/hour

time taken to cover first 30 km is given by

t_{1} =\frac{30}{v}           ( time=\frac{distance}{speed})

for next 17 km the speed of bicyclist is 2 km/hour greater than his original speed

so the speed to cover next 17 km = v+2

time taken to cover next 17 km is given by

t_{2} =\frac{17}{v+2}

now total time t spent by the bicyclist to cover entire trip is given by

t=t_{1} +t_{2}

t=\frac{30}{v} +\frac{17}{v+2}

now if v=18 , we have

t=\frac{30}{18} +\frac{17}{20}

now to add fractions we make the denominator same

Hence we will find the LCM of 18 and 20

LCM of 18 and 20 = 180

now we need to make both the denominator equal to 180

t=\frac{30(10)}{18(10)} +\frac{17(9)}{20(9)}t=\frac{300}{180} +\frac{153}{180} =\frac{300+153}{180}

t=\frac{453}{180} =2.52 hours (approx)

A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The vo
Evgen [1.6K]

Answer: 17 cm

Step-by-step explanation:

For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:

V = B*H

Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3

Then:

B = 3cm^2

V = 51cm^3

If we replace those in the equation above, we get:

51 cm^3 = (3cm^2)*H

Solving this for H gives:

(51 cm^3)/(3 cm^2) = H = 17 cm

The height of the tubing is 17 cm

The sides of a rectangle have length x+ 2 and width x -5. Which equation describes the area, A, of the rectangle in terms of x?​
Yakvenalex [24]

Answer:

The area in factored form is A=(x+2)(x-5).

The area in standard form is A=x^2-3x-10.

Step-by-step explanation:

The area of a rectangle is length times width.

So the area here is (x+2)(x-5).

They are probably not looking for A=(x+2)(x-5) because it requires too little work.

They probably want A in standard form instead of factored form.

Let's use foil:

First x(x)=x^2

Outer: x(-5)=-5x

Inner: 2(x)=2x

Last: 2(-5)=-10

---------------------Adding together:  x^2-3x-10.

The area in factored form is A=(x+2)(x-5).

The area in standard form is A=x^2-3x-10.
