Well, 4.4 + 7.7 = 12.1
So that would be 12 tonnes
<u>Or </u>
4.4 = 4 tonnes
and
7.7 = 8 tonnes
Hope this helps
X = 20
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20
Let x equal the larger number
Let y equal the smaller number
x+y=63
x=y+11
Sub the second equation into the first equation and solve for y
y+11+y=63
2y+11=63
2y=63-11
2y=52
y=52/2
y=26
Sub y into the second equation
x=y+11
x=26+11
x=37
Hope this helps!
A right angled triangle can be formed from the given scenario as shown below in the figure:
We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.
sine of the angle relates its perpendicular side to hypotenuse as:
sin(x) = perpendicular/hypotenuse
⇒
Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet
This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
#1 = -2 over -3. #2= y - (3.8)= 2.6(x-5.1)
