Which is an equivalent form of the expression 1800(1.2)^-t
ololo11 [35]

Answer:

1800(5/6)^t

Step-by-step explanation:

I don't see any answer choices, but this would be another form if it is listed. The negative exponent means that you get the reciprocal of the fraction (in this case 1.2). This turns 1.2 into (1/1.2), which is equivalent to 5/6.

Find the HCF and LCM of 126 and 234?
Leni [432]

Answer:

Below in bold.

Step-by-step explanation:

Find the prime factors:-

126 = 2 * 3 * 3 * 7

234 = 2 * 3 * 3 * 13

So the GCF =  2 * 3 * 3 = 18.

The LCM = 2 * 3 * 3  * 7 * 13

= 1638.

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = 20 and h = 14 , then

A = \frac{1}{2} × 20 × 14 = 10 × 14 = 140 in²
