After driving to a riverfront parking lot, Bob plans to run south along the river, turn around, and return to the parking lot, r

mars1129 [50]

Answer:A) 1.5

Step-by-step explanation: Bob runs at the rate of 8mins per mile

In 60mins his rate would be=60/8=7.5

Let a be the distance he further runs south

2s+3.25

Total distance covered in 50mins=Time=distance/speed=

50/60

50/60=2s +3.25/7.5

Cross multiply

60(2s+3.25)=50×7.5

120s+195=375

120s=375-195

S=180/120

S=1.5

Subtract the cube root of the product of h and 3k from the square of the sum of p and q

ehidna [41]

Answer:

(p + q)² - ∛(h·3k) or (p + q)² - ∛(h·3k)

Step-by-step explanation:

Cube root of x: ∛x

Product of h and 3k: h·3k

Sum of p and q: p + q

*****************************

From (p + q)² subtract ∛(h·3k) This becomes, symbolically:

=> (p + q)² - ∛(h·3k)

What is the volume, in cubic feet, of a cone that has a base area of π / 4 square feet and a height of 3 feet?

rewona [7]

$The\ volume\ of\ a\ cone:V=\frac{1}{3}B\cdot H\\\\B=\frac{\pi}{4}ft;\ H=3ft\\\\therefore\\\\V=\frac{1}{3}\cdot\frac{\pi}{4}\cdot3=\boxed{\frac{\pi}{4}\ (ft^2)=\frac{1}{4}\pi\ (ft^2)}$

2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).

ArbitrLikvidat [17]

Answer:

(a) $a= \frac{F}{m}$

(b) $a = \frac{1}{5}$ units.

(c) m = 10 units

Step-by-step explanation:

Force (F), mass (m) and acceleration (a) are related by the equation F = ma.

(a) We have to solve this equation for a.

So, F = ma ........ (1)

⇒ $a= \frac{F}{m}$ ..... (2) (Answer)

(b) If F = 1 units and m = 5 units, then from equation (1), we get

$a = \frac{1}{5}$ units. (Answer)

(c) If F = 25 units and a = 2.5 units.

Then from equation (1), we get,

$m = \frac{F}{a} = \frac{25}{2.5} =10$ units. (Answer)
