Answer:

g = vt/(v - t)

Step-by-step explanation:

See the solution in steps:

1/t = 1/g + 1/v
1/g = 1/t - 1/v
1/g = (v - t)/(vt)
g = vt/(v - t)

Learning Task 1: Read and analyze each problem carefully. Write your final answer in your notebook based on the given questions

solmaris [256]

Solving the given problems using the appropriate arithmetic operation such as multiplication, divison and addition, the answers are :

4 people
1000 ml
$1960

Total size of pizza = $2 \frac{2}{3} = \frac{8}{3}$

Number of pizzas gotten by each person = $\frac{2}{3$

Number of people sharing pizza :

$\frac{8}{3} \div \frac{2}{3} = \frac{8}{3} \times \frac{3}{2} = 4 \: people$

2.)

Volume bottle = 600 ml

Fraction of water = $\frac{3}{5}$

Volume of full bottle = $\frac{3}{5} \times n = 600 = \frac{3n}{5} = 600$

Volume of full bottle = $\frac{3n}{3000}$

Volume of full bottle = $n = \frac{3000}{3} = 1000 ml$

3.)

Amount left = Php. 980
Fraction spent = $\frac{4}{8}$

Let the monthly salary = m

Fraction left = $1 - \frac{4}{8} = \frac{4}{8} = \frac{1}{2}$

Hence,

$\frac{1}{2} \times m = 980$

$\frac{m}{2} = 980$

$m = 980 \times 2 = 1960$

Therefore, Joel's monthly salary is $1960

Henry wants to buy a new table saw for his carpentry shop. He has saved $360 which is 2/3 of the price of the saw. How much does

Tema [17]

If 360 is 2/3 of the full price on a saw then your equation should look like this:

$360=\frac{2}{3} *x$

x is your unknown full price of the saw. Just solve for x now.

$360=\frac{2}{3} *x\\ \\ x=\frac{3}{2} *360=540$

This means that the full price is $540.

Hope this helps!

Batman (mass=100 kg) jumps straight down from a bridge in to a boat (mass = 580 kg) in which a criminal is fleeing. The velocity

Crank

Answer:

$v_b=11.94\ m/s$

Step-by-step explanation:

Linear Momentum

The momentum of a system of masses m1,m2,m3... with speeds v1,v2,v3,... is given by

$M=m_1v_1+m_2v_2+m_3v_3+...$

When some interactions take place into the system of masses with no external forces interferring, the total momentum is not changed, which means that if the new speeds are v1', v2', v3'... then:

$m_1v_1+m_2v_2+m_3v_3+...=m_1v_1'+m_2v_2'+m_3v_3'+...$

The problem relates the story of Batman (m1=100kg) who is initially assumed at rest and lands on a boat with mass m2=580 kg initially moving at 14 m/s to the positive reference. When the collision takes place, both masses join and a common speed $v_b$ is achieved by the common mass. Applying the conservation of momentum, we have
