1 answer:

8 0

3 - 8r <= 3 + 4r
3 - 3 <= 4r + 8r
0 <= 12r
0 <= r

-6+ 4r < 2+ 4r
4r - 4r < 2 + 6
0 < 8
all real numbers

The "or" statement means combining the sets of solutions.

combined sets = all real numbers

Water has a density of about 62.5 pounds per cubic foot snow has lower density than water but that density can vary greatly. sup

Anastasy [175]

Answer:

$2,133.33\ pounds$ or $2,133\frac{1}{3}\ pounds$

Step-by-step explanation:

step 1

Find the volume of the snow

Convert inches to feet

1 ft=12 in

8 in=8/12=(2/3) ft

$V=(40)(5)(2/3)=(400/3)\ ft^{3}$

step 2

Find the mass of the snow

Multiply the density by the volume

$m=(400/3)*16=2,133.33\ pounds$

$2,133.33=2,133\frac{1}{3}\ pounds$

The area of a rectangle is 14 square units. It has side lengths a and b. Given the following value for a, find b. a = 2 & 1/

tino4ka555 [31]

Given:

The area of a rectangle = 14 square units.

The side lengths are a and b.

$a=2\dfrac{1}{3}$

To find:

The value of b.

Solution:

We know that, the area of a rectangle is:

$Area=Length\times Width$

The area of the given rectangle is:

$14=a\times b$

$14=2\dfrac{1}{3}\times b$

$14=\dfrac{2(3)+1}{3}b$

$14=\dfrac{6+1}{3}b$

On further simplification, we get

$14=\dfrac{7}{3}b$

$14\times 3=7b$

$42=7b$

Divide both sides by 7.

$\dfrac{42}{7}=b$

$6=b$

Therefore, the value of b is 6 units.

Arisa [49]

Therefore, the bones were 6612.5 years old at the time they were discovered.

Given that the radioactive element carbon-14 has a half-life of 5750 years, and a scientist determined that the bones from a mastodon had lost 57.5% of their carbon-14, to determine how old were the bones at the time they were discovered, the following calculation must be made:

50 = 5750
100 = 11500
57.5 = X
57.5 x 11500 / 100 = X
6612.5 = X

Therefore, the bones were 6612.5 years old at the time they were discovered.

If a person walks 1/3 a mile in each 1/2 hour, how far does he walk in 1 hour.

serg [7]

Distance travelled in 30 minutes = 1/3 miles

Distance travelled in 1 minute = 1/(3 × 30)

Distance travelled in 60 minutes = (1 × 60)/(3 × 30)

= 2/3 miles
