A student skipped a step when she tried to convert 18 hours into seconds,and she got the following incorrect result:
18 hours
60 seconds)
= 1080 seconds
1 minute
What conversion ratio did she skip in this multiple-step conversion?

Answers

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = $18* 60 minutes$

= $1080 minutes$ .

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = $1080* 60 seconds$

= $64800 seconds$ .

Thus, 18 hours = 64800 seconds.

As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.

Which expression is equivalent to 16^3?
6^7
2^11
2^12
2^64

Answers

Answer:

2¹²

Step-by-step explanation:

= 16³

We'll divide 16 into the product of its prime factors

= ( 2×2×2×2)³

There are four 2s so it becomes 2⁴

= (2⁴)³

= 2⁴ˣ³

= 2¹²

Answer:

2^12

Step-by-step explanation:

16^3 = (2^4)^3 = 2^(4x3) = 2^12

Hope this helps!

What is the length of AB.

Answers

To find the length of AB in triangle ABC with $BAC = BCA = 50^\circ$ , apply the Law of Sines. Solving for x, we find x = 3. Substituting this into AB = 4x, the length of AB is 12 units, corresponding to answer (d).

To find the length of AB, we can use the Law of Sines in triangle ABC:

$(AB)/(\sin BAC) = (BC)/(\sin BCA)$

Substitute the given values:

$(4x)/(\sin 50^\circ) = (2x + 6)/(\sin 50^\circ)$

Cancel out $\sin 50^\circ$ from both sides:

4x = 2x + 6

Subtract 2x from both sides:

2x = 6

Divide by 2:

x = 3

Now, substitute x = 3 back into AB = 4x:

$AB = 4 * 3 = 12$

So, the correct answer is (d) 12.

Applying the Law of Sines to triangle ABC with angles $BAC = BCA = 50^\circ$ , we find x = 3. Substituting into AB = 4x, the length of AB is 12 units. The Law of Sines relates the lengths of sides in a triangle with the sine of their opposite angles, enabling the determination of AB as 12 units (option d).
