Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825
Answer:
Step-by-step explanation:
1.) 9.99d+12.99c
2.) (you plug in the values)
9.99(1.5)+12.99(2.5)
3.) 23.985+ 32.475
4.) (round) 59.9625
59.96$
Answer:
x = 5 and -6
Step-by-step explanation:
Using the intersecting chord theorem which states that the products of the lengths of the line segments on each chord are equal.
Hence:
let
a = 6, b = 5, c = x+1 and d = x
Therefore, ab = cd
6*5 = x(x+1)
30 = x²+x
x²+x - 30 = 0
x²+ 6x - 5x - 30 = 0
x(x+6) - 5(x+6) =0
(x-5)(x+6) = 0
x-5 =0 and x+6 = 0
x = 5 and -6
Answer:
140
Step-by-step explanation:
1 and 3 are vertical angles meaning they are equal. 4 and 3 make a straight angle. A straight angle is 180.
180-140=40
2 and 4 are straight angles so should be equal.
1=140
2=40
3=140
4=40
