Approximate the distance between (0, -5) and (4, 1) to the nearest tenth, if necessary.
frutty [35]

Answer:

7.7

Step-by-step explanation:

To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,

Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5  4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:

4²+6²=c²

24+36=c²

√60=c

c=7.74....

But all we need is until the tenths so the answer is 7.7 (as the hundredths digit, 4, rounds down)

30 PTS <br> Please make sure everything is easy to understand
Semenov [28]
So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24
