Answer:
Q= 8
The amount emptied is 8 gallons of water
Step-by-step explanation:
First we need to create the equation for the above statement.
Q is directly proportional to the square of d
Q= kd²
Q= 50
d= 5
50= k5²
50 = k25
K = 50/25
K = 2
K is the constant of proportionality.
Now our equation is
Q= 2d²
Where Q = volume in gallons
d = pipe diameters in inch
For a pipe of diameter 2 inch
The amount of gallons of water emptied assuming the same kinf of flow is
Q= 2d²
Q= 2(2)²
Q= 2(4)
Q= 8
The amount emptied is 8 gallons of water
Answer:
$30
Step-by-step explanation:
since they exchanged them we can assume they are worth the same
250=4250
First find how many pesos is worth 1 dollar
4250/250= 17
Then divide the amount the sweater costs by how much 1 dollar would be
510/17= 30
The sweater would cost 30 dollars.
1.) Set up an equation.
All of the angles in a triangle have a sum of 180°. This means that in order to solve this problem, you have to add up all of the angle measures. Since we already know they add up to 180°, then the algebraic equation will look like:
2.) Simplify.
We can see that there are two variables and two known numbers. To make the equation simpler, add up the numbers that are compatible with each other.
--> 
3.) Isolate y.
If 180 is 44 more than 2y, then that means we can flip this and say that 2y is 44 less than 180. Numerically, this would be:
--> 
---> 
Isolate y using the same concept.
--> 
We are left with 
.
4.) Check your work.
Now that we know the value of y, all that's left to do is to plug in the value to see if your answer is true.
--> 
---> 
So we know it is true that y = 68°. Hope this was helpful.
Answer:
a = -0.8b
Step-by-step explanation:
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4b' to each side of the equation.
5a + 4b + -4b = 0 + -4b
Combine like terms: 4b + -4b = 0
5a + 0 = 0 + -4b
5a = 0 + -4b
Remove the zero:
5a = -4b
Divide each side by '5'.
a = -0.8b
Simplifying
a = -0.8b
