</span>(6m5 + 3 – m3 – 4m) + (m5 – 2m3 + 4m – 6)
Rewrite terms that are subtracted as addition of the opposite.
6m5 + 3 + (–m3) + (–4m) + m5 + (–2m3) + 4m + (–6)
Group like terms.
[6m5 + m5] + [3 + (–6)] + [(–m3) + (–2m3)] + [(–4m) + 4m]
Combine like terms.
7m5 - 3 - 3m3

The resulting polynomial in standard form would be given as:
7m5 - 3m3 - 3

What is 0.316 in expanded form.
RUDIKE [14]
Uhm, I'm pretty new to expanded form but I think it's something like:
(3 × 1/10) + (1 × 1/100) + (6 × 1/1000)
You can also write it as:
0.3 + 0.01 + 0.006

A worker is exposed to 98 dB for five hours and 82 dB for three hours, giving an eight-hour working day. On average, what noise
julia-pushkina [17]

Answer:

92 dB

Step-by-step explanation:

Use the mean formula, mean = sum of elements / number of elements.

Since it is a 8 hour work day, there are 8 elements.

mean = sum of elements / number of elements

mean = (98 + 98 + 98 + 98 + 98 + 82 + 82 + 82) / 8

mean = 736 / 8

mean = 92

So, the average noise level is 92 dB

Find the measure of CP
dmitriy555 [2]

Given:

A figure ABCP.

To find:

The measure of CP.

Solution:

In triangles ABP and CBP,

\angle PAB\cong \angle PCB            (Given right angles)

\angle ABP\cong \angle CBP            (Given)

BP=BP            (Common side)

Now,

\Delta ABP\cong \Delta CBP        (By AAS property of congruence)

We know that the corresponding parts of congruent triangles are congruent.

AP=CP

8=CP

Therefore, the measure of CP is 8 units.
