Which list is in order from least to greatest? A) 9.4 * 10^-8, 9.25 * 10^-6, 2.5 * 10^3, 7* 10^3 B) 2.5 *10^3, 7 * 10^3, 9.25 *

vladimir1956 [14]

ANSWER

A) 9.4 * 10^-8, 9.25 * 10^-6, 2.5 * 10^3, 7* 10^3

EXPLANATION

The numbers are given in standard form.

The first criteria we will use to order them is the exponents.

The bigger the exponents the bigger the number.

The second criteria is that, if the exponents of any two numbers are the same, then we use the numbers multiplying the powers of 10 to order.

$9.4 * 10^{-8} \: < \: 9.25 * 10^{-6} \: < \: 2.5 * 10^3 \: < \: 7* 10^3$

The correct choice is A.

12 gallons of water fill a tank to 3\4 capacity.

harkovskaia [24]

Answer:

A. 16, B.32

Step-by-step explanation:

We will say that $T$ is the total capacity of the tank.

Since 12 gallons of water fill the tank to 3/4 capacity, we know that 12 gallons is 3/4 of the total capacity. Hence,

$12=T \cdot \frac{3}{4}$ .

The last equation tells us that $T=\frac{4\cdot 12}{3}=16$ .

We will say that D is the number of half-gallon bottles that can be filled with the water of the tanke, note that D times 1/2 must be the total capacity of the tank. Hence,

$D \cdot \frac{1}{2}=16$

and so, we get that $D=2 \times 16=32$
