A small submarine starts at - 1.260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes What expression represents the new position of the submarine in relation to sea level?
Answer:
The submarine is at -1260 ft.
It descends 5 ft/min for 12 min.
12 min * 5 ft/min = 60 ft.
It descended 60 ft, so you must subtract 60 ft from -1260 ft.
-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft
The error in the last line in the problem is that (-5)(12) = -60, not 60.
The correct line is:
-1260 + (-5)(12) = -1260 - 60 = -1320

Answer:
w(15)=112.5
Step-by-step explanation:
All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.
In this case, you make the equation w(15)=7.5(15) which you can rewrite as
w(15)= 7.5×15, which gives . you 112.5 as the product.

There were 3 boys for every 4 girls in the group if there was 20 girls how many students went on the trip.
Answer:
35 students
Step-by-step explanation:
If there are 4 girls, then there are 3 boys
You will multiply both by 5 to get 20
So 3×5 is 15
20+15 = 35
Answer: 35 students
Explanation: Divide 4 into 20 to see how many sets of 4 girls there are. So there are 5 sets of four girls.
Five times three is 15.
In total (15 + 20), there are 35 students.

The roots of x² - 4x = 5, in ascending order, are what?? PLEASE HELP
Answer:
Step-by-step explanation:
x^2 - 4x - 5 = 0
(x - 5)(x + 1) = 0
x - 5 = 0
x = 5
x + 1 = 0
x = -1
We want to find the roots of a quadratic equation, to do that, we will use the Bhaskara's formula.
For an equation like a*x^2 + b*x + c = 0
The solutions are given by:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
Using that formula we will get that the solutions in ascending order are -1 and 5.
Now let's see how to get that:
We have expression: x^2 - 4x = 5
We can rewrite this as:
x^2 - 4x - 5 = 0
Now we can use the Bhaskara's formula to get:
[tex]x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*(-5)} }{2*1} = \frac{4 \pm6}{2*1}[/tex]
Then the two solutions are:
x = (4 + 6)/2 = 5
x = (4 - 6)/2 = -1
Then the solutions in ascending order are -1 and 5.
