24 - ( 1+3 ) = 20. 
20 + b(book weight; unknown) = answer

Since 4 x 5 is 20, the answer is that Toni can carry 5 books.

The longer leg of a 30,-60,-90 degree triangle is 18: what is the length of the other leg
taurus [48]

Answer:

The other legs are 9 and 9√3

Step-by-step explanation:

The longer side of a 30-60-90 degree rectangle is 18.

The other legs will be

\frac{x}{2}

and

\frac{x}{2}  \sqrt{3}

Where x is the longest side, which is given as 18.

Therefore one leg will be:

\frac{18}{2}  = 9

and the other leg will be:

\frac{18}{2}  \sqrt{3}  = 9 \sqrt{3}

What are the coordinates of each point after quadrilateral ABCD is reflected across the y-axis and then translated 2 units down?
zheka24 [161]

Answer:

A" =(-1,-1)    B" =(-2,1)

C" =(-4,1)    D" =(-5,-1)

Step-by-step explanation:

Given

A = (1,1)        B =(2,3)

C = (4,3)        D = (5,1)

Required

The new coordinates after reflected across y-axis and shifted 2 units down

When a point is reflected across the y-axis, the rule is:

(x,y)=>(-x,y)

So:

A = (1,1) => A' = (-1,1)

B =(2,3) => B' = (-2,3)

C = (4,3) => C' = (-4,3)

D = (5,1) => D' = (-5,1)

When a point is translated 2 units down, the rule is:

(x,y) => (x,y-2)

So:

A = (1,1) => A' = (-1,1) => A" =(-1,-1)

B =(2,3) => B' = (-2,3) => B" =(-2,1)

C = (4,3) => C' = (-4,3)=> C" =(-4,1)

D = (5,1) => D' = (-5,1) => D" =(-5,-1)

So, the new coordinates are:

A" =(-1,-1)    B" =(-2,1)

C" =(-4,1)    D" =(-5,-1)
