Y=4-7x
because it equals = -7
and
y= -5/4x + 2
because it equals = -5/4

if you multply two decimals that are less than 1 , can you predict whether the product will be less than or greater than either

nekit [7.7K]

Yes. Multiplying anything by a number less than one will decrease the original number. So multiplying two decimals will result in a number less than either one.

Can someone help maths

First find angle EBC.
The are for a triangle is 180 degrees.
It is a right triangle and has a right angle.
180 - (90 + 50)
180 - 140
angle EBC IS 40
NOW FIND X
The line is 180 degrees.
180 -40 = 140
X = 140 DEGREES

I need help with number 3

The hexagon divides the circle into 6 parts. That means the angle projecting each side is: 360°÷ 6 = 60°

The area of a circle is: πr²
78.54 in² divided by pi is 25 making the radius = 5

I would then use SOH CAH TOA to solve for the side.. knowing the hypotenuse is the radius and the angle to split it into a right triangle is 30°

Sin(30) = s/5
5*Sin(30) = s

12*s = perimeter hexagon
(remember s is half the hexagon side)

12*5*Sin(30) = perimeter hexagon
30 inches = perimeter
