Father is four times as old as Mary. Five years ago he was seven times as old. How old is the father now?

Answer:

If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.

I hope this helps!

Sort the following objects by length. Place the shortest object at the top.
Alenkinab [10]

Answer:

Ok, here we have two points A and B.

The shorter object will be the second option, AB with a line on top, this is a segment, so the length of this object is equal to the distance between A and B.

The next one is AB with an arrow pointing to the right, this is ray, is a line that starts in A and passes through B, and continues infinitely.

The third will be the bottom option, AB with a double-arrow on top, this is the notation for a line that passes through A and B, and it extends to infinity in both directions.

Answer:

The Proof is given below.

Step-by-step explanation:

Given:

\overline{HF}  bisect ∠ EHG.i.e

∴ ∠EHF ≅ ∠ GHF

\overline{EH} \cong \overline{GH}  

To Prove:

\overline{EF} \cong \overline{GF}  

Proof:

In  Δ EHF and Δ GHF

    EH ≅ GH     ………............{Given}

∠ EHF ≅ ∠ GHF     …………..{EF bisect ∠ EHG as given above}

     HF ≅ HF     ………............{Reflexive Property}

Δ EHF ≅ Δ GHF …................{ By Side-Angle-Side test}

∴ EF ≅ GF........{corresponding parts of congruent triangles (c.p.c.t).}

\overline{EF} \cong \overline{GF}  ....... PROVED
