Answer:

false

true

false

Step-by-step explanation:

if $a$ that would mean that "a" is on the left of 0 so the first one is false

every whole value is greater that 0, (except for 0) so the second one is true

if $|a|=0$ that would mean that "a" is 0 but by the line we see is false

Write 2.71x10-3 as an ordinary number.

Katyanochek1 [597]

Step-by-step explanation:

${2.71 \times 10}^{ - 3}$

This can be rewritten as

$2.71 \times \frac{1}{10^{3} }$

If we will solve this way,

$\frac{2.71}{1000} = 0.00271$

But since the denominator is just in terms of 1, we can just simply get the (-3). Note that we have to take the negative into consideration.

From the original position of the decimal point, move the decimal point 3 times TO THE LEFT. Therefore, from 2.71 we move the decimal point 3 times to the left, 0.00271.

If the exponent has a positive value, move TO THE RIGHT.

For example,

$2.71 \times {10}^{3} = 2.71 \times 1000 \\ = 2710$

Note that the exponent has a positive value. Therefore, we have to move the decimal point 3 times TO THE RIGHT. Producing 2710 as the answer.

a plane flies 480 miles with a 15 mph tailwind and then back 480 miles with a 15 mph headwind. if the plane completes the trip i

Minchanka [31]

Since we know the x and y, you would divide 480 by 15 and 32 miles per hour. Then you would multiply 7.2 by 32 and get 230.4. Your trying to find with wind and against wind so just times that by two and get 460.8. I think

In Area A, the insurance coverage rate for a wood frame house is 0.46%. In Area B, the insurance coverage rate for a wood frame

Karo-lina-s [1.5K]

To solve for the homeowner's insurance payment for house built in Area B, we simply multiply the cost of the house with the insurance coverage rate in its decimal equivalent. From the given problem,
annual insurance payment = ($65,900)(0.0054)
= $355.86
Thus, the answer is letter A.
