ANSWER:

For the first picture, it is the first answer. This is because of the Exterior Angle Theorem.

For the second picture, use the Exterior Angle Theorem again, but this time, solve for x.

$132 = x + (3x-24)\\132 = 4x - 24\\156=4x\\x=39$

The m∡B = 39°

A deep sea diving bell is being lowered at a constant rate. After 10 minutes, the bell is at a depth of 600 ft. After 40 minute

Degger [83]

<h2>Average rate of lowering per minute = 36.67 ft/min</h2>

Step-by-step explanation:

After 10 minutes, the bell is at a depth of 600 ft

After 10 minutes

Depth of bell = 600 ft

After 40 minutes the bell is at a depth of 1,700 ft.

After 40 minutes

Depth of bell = 1700 ft

Time gap = 40 - 10 = 30 minutes

Depth fallen = 1700 - 600 = 1100 ft

We have

Depth fallen = Average rate of lowering per minute x Time gap

1100 = Average rate of lowering per minute x 30

Average rate of lowering per minute = 36.67 ft/min

Find the common difference for the infinite arithmetic sequence shown.

mihalych1998 [28]

The common difference is 12

Further explanation:

It is given that the infinite sequence is an arithmetic sequence

The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

$a_1 = 211\\a_2 = 223\\a_3 = 235\\a_4 = 247........$

The common difference is denoted by d.

Here,

$d = a_2-a_1 = 223-211 = 12\\a_3-a_2 = 235-223 = 12$

The common difference is same for all proceeding terms.

So,

d = 12

27 1/5 over 4/5 as a unit rate

REY [17]

Answer:

$\frac{34}{1}$ or $34$

Step-by-step explanation:

we know that

To find the unit rate divide 27 1/5 by 4/5

but first

Convert mixed number to an improper fraction

$27\frac{1}{5}=27+\frac{1}{5}=\frac{27*5+1}{5} =\frac{136}{5}$

$\frac{136}{5}:\frac{4}{5}=\frac{136}{4}=\frac{34}{1}$
