Can someone please help?​

Answer:

I think it may be C) 5.5

Step-by-step explanation:

well the question doesn't really give us anything to work with to find the exact answer but if we look at the triangle logically then we will figure out that JZ is smaller than JS. and if JS is 8.7 then we can't have JZ being longer than JS so option D is out. and the other two options are way too short to be the length of JZ. Therefore we have option C as our winner

Hope this helps

The slope of a line is 2/3 . What is the slope of a line that is perpendicular to this line?
julia-pushkina [17]

The perpendicular line would have a slope of A) -3/2.

Perpendicular lines have opposite and reciprocal slopes.

To do the opposite, take the original slope (2/3) and change the sign (-2/3).

To do the reciprocal, take the slope we changed (-2/3) and flip it as a fraction (-3/2).

This gives us a new slope of -3/2.

BRAINLIEST + POINTS
Amanda [17]

The company matches up to 8%.

Multiply her salary by 8%:

66410 x 0.08 = $5,312.80


Her company will match 50% ( which is half the amount)

Divide the 8% total by 2:

5312.80 / 2 = 2656.40


The answer is B.

Answer:

15 x^8 y^3

Step-by-step explanation:

The area of a rectangle is given by

A = l*w  where l is the length and w is the width

A = ( 5x^6 y^2) *( 3x^2 y)

   = 15 x^(6+2) y^(2+1)

   = 15 x^8 y^3
