For the first one it is 2:9 second one 4:9 third 3:9
D because 6.2=100
6.2×1.4=8.68
so 100×1.4=140
140-100=40
so it's 40%

<span>4a is "You can find if a triangle is right by using the Pythagorean theorem or by using perpendicular lines"
</span><span>4b): Using the Pythagorean Side AC (which is √10 units long)^2 + side AB (which is √40 units long)^2 is equal to 50 (which is the length of side BC). Using perpendicular lines, you find that line AB has a slope of 1/3 and side AC has a slope of -3. Since these two are opposite reciprocals, they are perpendicular, which means that they form a 90 degree angle.
</span><span>5.) To find the midpoint, use the formula (x2+x1/2,y2+y1/2) by using the given coordinates, we find that the midpoint is (1,-2). This point lies in quadrant IV, so it is proven that it's midpoint lies in quadrant IV.

Answer:
77.39m + 15
Step-by-step explanation:
To simplify, we add all the common terms among themselves.
We have terms with the unit m and terms without any unit. So we add them among themselves.
59.95m − 30 + 7.95m + 45 + 9.49m
(59.95 + 7.95 + 9.49)m + (-30 + 45)
77.39m + 15
