Answer:

Step-by-step explanation:

distance = time * speed

4.9 =  1 second* speed

speed = 4.9/1 = 4.9 cm/sec

time = 15 1/2 = 31/2

distance = 31/2 *  4.9 = 75.95 cm

Answer:

75.95cm

Step-by-step explanation:

<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>

4.9 • 15 = 73.5

<u>4.9 divided by 2 will equal the 1/2 seconds</u>

4.9 ÷ 2 = 2.45

<u>add them all together</u>

73.5 + 2.45 = 75.95 cm

The point slope form of a line that has a slope of -2 and passes through point (5,-2) is shown below.
Likurg_2 [28]
Insert the point, (5,-2) with the slope of the line to figure out the equation. You can either use point-slope form, or plug it for for slope-intercept form.

Slope-intercept form:
-2 = -2(5) + b
-2 = -10 + b
Add 10 on both sides
8 = b

Thus,

y = -2x + 8

Answer is B

Pieces of Mail. The number of pieces of mail
Zina [86]

Answer:

20.8%

Step-by-step explanation:

The number of the pieces of mail handled by the U.S postal service decreased from 212,000,000,000 to 168,000,000

Therefore the percentage decrease can be calculated as follows

= 212,000,000,000-168,000,000,000

= 44,000,000,000/212,000,000,000 × 100

= 0.2075 × 100

= 20.8 %

Hence the percentage decrease is 20.8%

Arte-miy333 [17]

<em>Question:</em>

<em>The digit 8 in which number represents a value of 8 thousandths? </em>

Answer:

See Explanation

Step-by-step explanation:

The question requires options and the options are missing.

However, the following explanation will guide you

Start by representing 8 thousandths as a digit

\frac{8}{1000} = 0.008

i.e.

8 thousandths implies 0.008

Next;

Replace the 0s with dashes

_ . _ _8

Note that there are two dashes after the decimal point and before 8

PS: The dashes are used to represent digits

This implies that thousandths is the 3rd digit after the decimal point

Typical examples to back up this explanation are:

<em>17.008, 1.1489, 0.008 and so on...</em>
