What is the distance between 3, 5 and -4, 1

USPshnik [31]

Answer:

Distance = 8.06

Step-by-step explanation:

We have to use the distance formula $d=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }$ .

$(x_{1},y_{1}) =$ coordinates of the first point

$(x_{2},y_{2} ) =$ coordinates of the second point

To solve, plug the appropriate values into the formula.

$d=\sqrt{(-4-3)^{2} +(1-5)^{2} } = \sqrt{65} = 8.062257748$

What is the density of an object having a mass of 25 g and a volume of 8.0 cm cubed

weqwewe [10]

Answer:

3.125 g/cm³.

Step-by-step explanation:

The formula for density/mass/volume is d = m/v, where d is density in grams per cm cubed, m is in grams, and v is in cm cubed.

In this case, m = 25 and v = 8.0.

d = 25 / 8.0

d = 25 / 8

d = 3.125.

So, the density of the object is 3.125 g/cm cubed.

Hope this helps!

-26 times a number minus 22 is equal to 90 less than the number.

IgorLugansk [536]

Answer:

$x = \frac{68}{27}$

Step-by-step explanation:

Let x be the number

Write it out: -26x - 22 = x - 90
Combine like terms: -27x + 68 = 0
Subtract 68 from each side, so it now looks like this: -27x = -68
Divide each side by -27 to cancel out the -27 next to x. It should now look like this: $x = \frac{68}{27}$

I hope this helps!
