Answer:
1/2
Step-by-step explanation:
y=mx+c
so by comparing the two m=1/2
To see if these ratios make a proportion let us first change them into fractions
= 4:10 = 4/10 = 4 ÷ 2 / 10 ÷ 2 = 2/5
= 6:15 = 6/15 = 6 ÷ 3 / 15 ÷ 3 = 2/5
= Since both these ratios are getting simplified into a same fraction , they are proportional .
Therefore , 4 : 10 :: 6 : 15 ( 4 : 10 is proportional to 6 : 15 )
-6a - 4a + 7a = -10a + 7a = -3a, that isn't 5a;
b. False
The precent of increase is 20%
note that for a 30°-60°-90° triangle , the sides are 1, √3, 2
If the hypotenuse (2) is equal to 18, find the other lengths
First, find side (1). Divide 18 by 2
18/2 = 9
Next, multiply 9 with √3
9(√3) = 9√3
Finally, find the perimeter. Add all sides:
P = 18 + 9 + 9√3
P = 9√3 + 27
hope this helps
