Priya has a piece of string 5/6 yard long. She cuts 3/5 of the piece of string for a craft. What is the length of the string lef
Solnce55 [7]

Total length of the string = \frac{5}{6} yard

Length of string used for craft = \frac{3}{5} of total length of string

= \frac{3}{5} of \frac{5}{6}

= \frac{3}{5} \times \frac{5}{6}

= \frac{3}{6} yard

Length of the string left after use = Total length of the string - Length of string used for craft

Length of the string left after use = \frac{5}{6}-\frac{3}{6}

=\frac{2}{6}

Reducing it to the lowest term, we get

=\frac{1}{3} yard

Therefore, the length of string left is \frac{1}{3} yard.

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?
luda_lava [24]

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If  EJ is 3y-8 and JF is 7y-40.

Then, 3y-8=7y-40

\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}

JF= 7(8)-40 =56-40= 16 units

Hence, the length of JF = 16 units.
