What is the solution to the equation?

x – 1.2 = 3.6

Answers

To solve this you would work backwards so 3.6+1.2 because the operation in the equation is subtraction. 3.6+1.2= 4.8. I hope this helped. :)
To solve you add both sides by 1.2. This cancels out the negative 1.2 and when you add 1.2 to 3.6 you get 4.8. Now you're equation should look like x=4.8. And that's pretty much it

Jenny's great grandmother is 90 years old. Jenny is 12 years old, what percent of Jenny's great-grandmother's age is Jenny's age? Needs to be EXACT percent no decimal.

Answers

The required percentage of Jenny's great-grandmother age is Jenny's age is 13%.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

Jenny's great-grandmother is 90 years old and Jenny is 12 years old.

To calculate the percentage of Jenny's age compared to her great-grandmother's age, you can divide Jenny's age by her great-grandmother's age and then multiply by 100.

So, (12/90) × 100 = 13.33%.

However, the answer should be in exact percent with no decimal, so the answer is 13%.

A 500 g model train car traveling at 0.8 m/s collides with a 300 g stationary car. The cars hook up and move off down the track together. How fast are they going? ( also how do I do it )

Answers

Answer:

0.5ms^(-1)

Step-by-step explanation:

Let v be the speed after the collision of both the cars.

Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get

500{*}0.8+300{*}0=(500+300)v

400+0=800v

400=800v

v=0.5ms^(-1)

Thus, they are moving at the velocity of 0.5ms^(-1)

Answer:

0.5 m/s

Step-by-step explanation:

A 500 g model train car traveling at 0.8 m/s collides with a 300 g stationary car.

Initial velocity of train, v_T=0.8\ m/s

Initial velocity of car, v_C=0\ m/s

Mass of train, m_T=500\ g

Mass of car, m_C=300\ g

The cars hook up and move off down the track together.

Let the final velocity of car and train, v_T=v_C=v

Using conservation of momentum,

Momentum before collision = Momentum after collision

m_T* v_T+m_C* v_C=(m_T+m_C)* v

500* 0.8+300* 0=(500+300)* v

v=(400)/(800)

v=0.5\ m/s

Hence, After collision they will going with 0.5 m/s

(A fact family is a set of three [or two] numbers that can be related by addition and subtraction, for example: 7 = 4 + 3, 7 = 3 + 4, 7 - 4 = 3, and 7 - 3 = 4. When the number is a double, there are only two members of the fact family. An example would be 10 - 5 = 5, and 5 + 5 = 10.)i hope i helped u
