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:
10 hours.
Step-by-step explanation:
2 cartoon strips takes 5 hours
divide 5 by 2 to give us how much time is used for 1 strip
5/2 = 2.5 which is equal to 1 strip
Now the question is asking you how much will time for 4 strips?
Take 4 and multiply it by 2.5
4x2.5 = 10
Answer:
Catalina skates a total of 120 feet
Step-by-step explanation:
In order to determine how far she skates, create a right triangle. We know each legs' value with one being 30 and the other 40. Now we can find the hypotenuse by using the Pythagorean Theorem.
a^2 + b^2 = c^2
30^2 + 40^2= c^2
900 + 1600 = c^2
2500 = c^2
50 = c
Now that we have all 3 sides of the right triangle, add them together for the total distance.
30 + 40 + 50 = 120 feet
Answer:
31.25%
Step-by-step explanation:
12-8.25=$ 3.75
(3.75/12)*100=31.25%
Answer:
8.0 billion
Step-by-step explanation:
1.2÷100=0.012
0.012×6.5=0.078
2017-2001=16
0.078×16=1.248
6.5+1.248=7.748
nearest tenth 8.0
