500+180=680=6.80
Answer:
8 minutes
Step-by-step explanation:
Step one:
given
A submarine is 105 feet below the surface of the water
depth of submarine= 105 feet
let the time of ascending be x
Required
The time taken to ascend up to 81 ft
Step two:
the expression for the situation is
<em>81=105-3x</em>
solve for x
3x=105-81
3x=24
divide both sides by 3
x= 24/3
x=8 minutes
Answer:
$13,000 at 7% and $12,000 at 4%
Step-by-step explanation:
Use formula:
where
I = interest,
P = principal,
r = rate (as decimal),
t = time (in years)
<u>7% rate:</u>
P = $x
r = 0.07
t = 1 year
Then
<u>4% rate:</u>
P = $(25,000 - x)
r = 0.04
t = 1 year
Then
If he receives an annual return of $1,390, then
so
Answer:
b = 49 cm
Step-by-step explanation:
Volume of a rectangular prism = width × length × height
Given:
- volume = 48,608 cm³
- width = 16 cm
- length = b
- height = 62 cm
Substituting the given values into the formula and solving for b:
⇒ 48608 = 16 × b × 62
⇒ 48608 = 992 b
⇒ b = 48608 ÷ 992
⇒ b = 49

Which proportion best compares age and tattoos?
The row data represents the age range of each group while the column data represents the amount of tattoo by each group.
So, to make comparison:
You simply pick a cell data and compare it to the row total.
<u>Take for instance</u>
For those who have at least 1 tattoo. The proportion to use are:
<em>170/490 --- For age range: 18 - 29</em>
<em>60/505 --- For age range: 30 - 29</em>
<em />
For those without tattoo. The proportion to use are:
<em>320/490 --- For age range: 18 - 29</em>
<em>445/505 --- For age range: 30 - 29</em>
