Answer:
-6.
Step-by-step explanation:
if A(-4;-7) and B(-2;-19), then the required slope can be calculated according to the next formula:
Mid ocean ridges are formed when two tectonic plates are drifting away from each other. This is known as a divergent or constructive plate boundary. Mid ocean ridges are formed as two oceanic plates move away from each other. The plates move as a result of convection cells in the mantle that generate convection currents. An example of a midocean ridge is the Mid Atlantic ridge where African plate drifts away from the north and south American plates.
90ft by 7ft gives an area of:
90 x 7 = 630 sq ft
1/2 fl oz is needed for each square foot
630 x 1/2 = 315 fl oz required.
Answer:
7:63
Step-by-step explanation:
It's a 1 to 9 ratio, which means the second number is 9 times bigger.
To make it equivalent, you need to make 7 9 times bigger as well.
7x9=63
Answer: 7:63
Answer:
64
Step-by-step explanation:
9×10=90-8=82
3×10-12=18
82-18
