54 divided by 4.5 step by step

1 answer:

7 0

54/4.5 = 12

Set it up as long division, with 54 "inside" the division sign and 4.5 outside. Then you have to move the decimal on 4.5 to the right once, which will give you 45 on the outside. You also have to move the decimal over 1 more place on the 54, which will give you 540 on the inside. Then figure out how many times 45 can go into 54, which is once. Then subtract 45 from 54, which will give you 9. Then you are left with 90 on the inside and 45 goes into that 2 times.

Calculate the length of AC

Liono4ka [1.6K]

Answer:

Length of the side AC is 12 units.

Step-by-step explanation:

Here, in the triangle ABC

Base = 5 units

Let, Perpendicular = k units

Hypotenuse = 13 units

In a Right angle triangle, by PYTHAGORAS THEOREM:

$(Base)^{2} + (Perpendicular)^{2} = (Hypotenuse)^{2}$

Similarly, in triangle ABC

$(AB)^{2} + (AC)^{2} = (BC)^{2}$

or, $(5)^{2} + (k)^{2} = (13)^{2}$

⇒ $k^{2} = 169 - 25 = 144$

⇒ k = 12, or k= -12

But as k is the length of a side of a triangle so, k ≠ -12

⇒ k = 12

Hence, the length of the side AC = 12 units.

The line parallel to x-3y=-12 that passes through (-3,4)

gulaghasi [49]

X-3y=12
3y=x-12
y=1/3x-4
parallel means same gradient, which is 1/3.
Use formula y-y1=m(x-x1), m=gradient and y1 is y coordinate of point and x1 is x coordinate of point.
y-4=1/3[x-(-3)]
y-4=x/3+1
y=x/3+5
