Three times = 3 ×
<span>The difference of 65 and 48 = 65 - 48 = 17
(Difference = subtract)
That equals 3 </span>× 17
<span>
Answer = 3 </span>× 17
<span>(3 </span>× 17 = 51)<span>
Hope this helped☺☺

Answer: 200cm long
Step-by-step explanation:
Let the length of the rod be x
red = 1/4 of the rod , which means 1/4 of x
orange = 2/5 of x
The remainder = x - (
+
)
= x - (
)
= 
yellow = 2/7 of the remainder , that is
yellow = 2/7 of
yellow = 
and it was given that the yellow section was 20cm long , that is
= 20cm
x = 20 x10
x = 200
Therefore the rod was 200cm long
Answer:
Sin is the function of an angle
it is the ratio of the length of the side that is opposite of that angle to the length of the longest side of the triangle
Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
