Answer:

The required equation is [tex]s =\frac{3}{10} m[/tex]

Step-by-step explanation:

Given: The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.

To find : Which equation relates the mass of the object, m, and the length of the spring, s?

Solution :

Let the mass of the object  m,

Length of the spring s,

When a 30-gram object is attached, the spring stretches 9 centimeters.

i.e, the times length of the object is attached to spring is The length of a spring varies directly with the mass of an object that is attached to it.

According to question,

i.e, length of the spring is 3 by 10 times the mass of the object.            

Therefore, The required equation is

Answer:

3.2

Step-by-step explanation:

first expand the bracket, (2^3 -6 )= (2 x 2 x 2) - 6= 8 - 6 = 2

so, 6.4/2= 3.2

Answer:

So, the first solution is a calculator but sometime we don't have a calculator so, do

200 X 300 = A

40 X 90 = B

9 X 8 = C

then add just do multiplication from there like

A + B = D

D + C = E

Then your finally answer would be E

Hope that helps that's the way I do math quick in my head

[tex]2^{6}[/tex]

When you have powers in this fashion, all we need to do is multiply the two to get our answer.

Now we can solve:

2 x 2 x 2 x 2 x 2 x 2

4 x 4 x 4

16 x 4

64

I hope this helps! :)

(I have attached an example for reference)

1) Product means multiply, so we will multiply the decimal numbers.

2) First multiply both the numbers just the way you multiply two whole numbers.

3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.

4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.

5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

Answer:

You can purchase 10 songs after buying 12 videos.

Step-by-step explanation:

Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.

Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.

Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.

Answer:

y=5x-1/4

Step-by-step explanation:

The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.

Answer:

The calculation to your equation is:

Y=5x-1/4
