Answer:
<em>The sea cow can stay under water for 16 minutes.</em>
Step-by-step explanation:
A hippopotamus can stay under water for 15 minutes.
A sea cow can stay under water minutes and this is 11 minutes longer than one-third the time a hippopotamus can.
So, "11 minutes longer than one-third the time a hippopotamus can" means:
Thus, the equation will be:
Now, solving the above equation, we will get.........
So, the sea cow can stay under water for 16 minutes.

Answer:
c) 10
Step-by-step explanation:
3(2t +5) = 5t + 25
distribute the 3 into the parentheses
6t + 15 = 5t + 25
subtract 5t from both sides
t + 15 = 25
subtract 15 from both sides
t = 10
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)
The value of shortest side of quadrilateral is 11 meters.
Let the shortest side be x. So, the other three sides of quadrilateral will be (x + 1), (x + 2) and (x + 3). The perimeter of quadrilateral will be the sum of all the sides of quadrilateral. Representing the equation for same -
x + x + 1 + x + 2 + x + 3 = 50
Performing addition on Left Hand Side of the equation
4x + 6 = 50
Shifting 6 to Right Hand Side of the equation
4x = 50 - 6
Performing subtraction on Right Hand Side of the equation
4x = 44
Shifting 4 to Right Hand Side of the equation
x = 44 ÷ 4
Performing division on Right Hand Side of the equation
x = 11
Therefore, the shortest side fo quadrilateral is 11 meters.
