If you have 30$ and you need to find 8%, and add to 30$ then find 15% of that, and what’s your total?
stira [4]

Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now  8 % of $30 = \frac{8}{100}  \times 30 = 2.4

or, 8% of $30  = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4  = $32.4

Finding 15% of the total $32.4,

we get  \frac{15}{100} \times 32.4 = 4.86

or, 15% of $32.4   = $4.86

hence, our total amount value is $4.86.

What is the distance between the points (-4,2) and (3,-5)
34kurt

Answer:

7√2 units

Step-by-step explanation:

The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

\sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

Here, x1=-4 and y1=2

x2=3 and y2=-5

\sqrt{ {(3  - ( -  4))}^{2}  +  {( - 5 - 2)}^{2} }

\sqrt{ {(3 + 4)}^{2}  +  {( - 7)}^{2} }

\sqrt{ {(7)}^{2}  +  {( - 7)}^{2} }

\sqrt{49 + 49}  = 7 \sqrt{2}
