A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for a total revenue
stepladder [879]

Answer:

9 right-handed gloves and 3 left-handed gloves were sold.

Step-by-step explanation:

Given:  In one month, 12 gloves were sold for a total revenue of \$561.

            right-handed gloves cost \$45 and left-handed gloves cost \$52.

To find: How much of each type of gloves did they sell?

Solution: Let they sell x  right-handed gloves, and y left-handed gloves.

Now, cost of each right-handed gloves =\$45

cost of each left-handed gloves =\$52

Total revenue =\$561

So, we get

45x+52y=561\:\:\:...(i)

Also,  in a month 12 gloves were sold.

So, we get

x+y=12\:\:\:...(ii)

Now, from (ii) we get, x=12-y.

Putting x=12-y in equation (i), we get

45(12-y)+52y=561

\implies 540-45y+52y=561

\implies7y=561-540

\implies7y=21

\implies y=\frac{21}{7}

\implies y=3

Now, putting y=3 in equation (ii), we get

x+3=12

\implies x=12-3

\implies x=9

Hence, 9 right-handed gloves and 3 left-handed gloves were sold.

Question 12(Multiple Choice Worth 1 points)
salantis [7]

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent " ⇒ 3rd answer

Step-by-step explanation:

In a translation,

  • Every point of the object must be moved in the same direction.
  • Every point of the object must be moved for the same distance.
  • The lines drawn from each point to its image are parallel and congruent.

The rules of translation:

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units  then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units  then its image is (x , y - k)

∵ Δ JOY is translated using the rule (x, y) → (x + 3, y - 2)

∵ Δ J'O'Y' is its image after translation

- That means each point move 3 units to right and 2 units town

∵ Line segment JJ' joins the vertex J by its image J'

∵ Line segment OO' joins the vertex O by its image O'

- The lines drawn from each point to its image are parallel

   and congruent

∴ JJ' // OO'

∴ JJ' ≅ OO'

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent "
