What is 19+11+77-2/10? for math points
DENIUS [597]

Answer: 19 + 11 = 30 + 77 = 107 - 2/10 = 106.8

If you're confused by the fraction just do 2 divided by 10 and you should get 0.2.

So, instead of doing 2/10 you can do:

19 + 11 = 30 + 77 = 107 - 0.2 = 106.8

Have a good day!

To the nearest tenth, what is the distance between the points (1, –2, 5) and (0, 7, –4)?
Eduardwww [97]

Answer:

The distance is 12.8\ units

Step-by-step explanation:

we know that

The formula to calculate the distance between two points is equal to

d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}+(z2-z1)^{2}}

we have

A(1,-2,5)\\B(0,7,-4)  

substitute the values

d=\sqrt{(0-1)^{2}+(7+2)^{2}+(-4-5)^{2}}

d=\sqrt{(-1)^{2}+(9)^{2}+(-9)^{2}}

d=\sqrt{1+81+81}

d=\sqrt{163}\ units

d=12.8\ units

$6.59 is 25% of what numbers?
Darya [45]

The answer is 26.36. If you were trying to figure out what is 25% of 6.59, you'd have to multiply, however you need to know what 6.59 is 25% of so you  do the opposite, just divide 6.59 by .25 and you'll get 26.36 which is your answer.
