6 x 89 is 534
6 x (90 - 1) is 534. BUT you have to subtract 90 from 1 and that's 89. So then you multiply 6 by 89.
6 x 90 is 540 and 6 x 1 is 6. you take 540 subtract 6 and that's 534.
540 - 6 is 534.

What is 846.28 rounded to the nearest tenth?

Murljashka [212]

846.3.

It is 846.3 because anything 5+ you round up. Anything 4- you round down.

In this case, you would round 8 up to 10. This then makes it 846.3.

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.
