Find the distance between the points 4,7 and -5,7

Mathematics
2 answers:
SashulF [63]2 years ago
6 0

<u>Distance formula is</u>: \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }

       (x_{1},y_{1}) = (4,7)\\(x_{2},y_{2}) = (-5,7)

Thus let us plug in all the know values and solve:

      \sqrt{(-5-4)^2+(7-7)^2} =\sqrt{(-9)^2} =\sqrt{81} = 9

Thus the <u>distance is 9</u>

<u></u>

Hope that helps!

soldier1979 [14.2K]

Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>

No, <u>Taylor's resoning is incorrect</u> because  2,800,000 = 2.8  * 10^{6}

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  2.8  * 10^{6}.  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, <u>Taylor's reasoning is incorrect. </u>

If 35 gms of pure drug are contained in 150 mls, how many grams are contained in 75 mls?
Leviafan [203]

Answer:

17.5

Step-by-step explanation:

The ratio of "pure drug" to liquid is 35:150

Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2

we can then multiply 35 by the ratio 1/2

35/2=17.5

State the answer

In 75 mls there are 17.5 grams of pure drug
