Answer:

A. 10 cm

Step-by-step explanation:

In a right angled triangle, a² + b² = c² where c is the diagonal or hypotenuse. If you split a rectangle diagonally into two right angle triangles, the a and b of both triangles would be the same length. Therefore, the c or diagonals would also be the same length - 10 cm.

Hope this helps!

Alexxandr [17]

Answer:

2500 kg/m³

Step-by-step explanation:

Density of a material is the ratio of mass and volume of that material.

The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)

Given density as 2.5 g/cm³ , convert to kg/m³

Formula is;

1g/cm³ = 1000 kg/m³

2.5 g/cm³=? cross-multiply

=2.5×1000 = 2500 kg/m³

I got (-6.28, -0.76). 

Step 1.) Write out the problems
   -2x=8-6y
   -15x=21-6y

Step 2.) Pick a problem and solve for X
   -2x=8-6y =  x=-4-3y

Step 3.) Plug in the x
    (-15)(-4-3y)= 21-6y
    60 + 45y= 21-6y

Step 4.) Solve for y
    y=-0.76

Step 5.) Plug in the y value into one of the equations
    -2x= 8- 6(-0.76)
    -2x= 8 + 4.56
     x= -6.28

Step 6.) Check your answers
    -2(-6.28)=8-6(-0.76)
    12.56=12.56

Step 7.) Write it out
   (-6.28,-0.76)
