Answer:
the actual distance is 1800 ft.
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
Let x be the actual distance.
As per the statement:
Reggie was looking at a map of the school the scale shows that 1 inch equals 150 ft.
⇒1 inch = 150 ft.
if the distance between his classroom in the cafeteria measures 12 in on the map.
by definition of proportions we have;
By cross multiply we have;
ft
Therefore, the actual distance is 1800 ft.
Use the Pythagorean theorem!
This principle applies to any right triangles.
This states the relationship between the sides that
(7)² + (24)² = x²
All you have to do is simplify at this point.
49 + 576 = x²
625 = x²
√ √
x = 25
You should try to memorize this right triangle. It can be very helpful in fast questionnaires, such as the SAT.
Ok there are 48000 mL in 48L.
Hello,
x^3+7x^2+10x-6=x^3+3x^2+4x^2+12x-2x-6
=x²(x+3)+4x(x+3)-2(x+3)
=(x+3)(x²+4x-2)
=(x+3)(x+2-√7)(x+2+√7)
zeroes={-3,-2+√7,-2-√7}
