Answer:
56.9
Step-by-step explanation:
cos y = 6/11
y = cos‐¹ (6/11)
= 56.9

Answer:
(2,-5)
Step-by-step explanation:
The vertex form is 
and has vertex (h,k). Remember h is the opposite value of the value in the equation.
This means 
has vertex (2,-5)
Answer:
There were 40 2-point questions and 9 3-point questions.
Step-by-step explanation:
To solve this situation, write two equations. One for the number of questions and one for the number of points.
Let x be the number of 2 point questions.
Let y be the number of 5 point questions.
x + y = 49
Now since x are each worth 2 points, the total points is 2x.
And since y are each worth 5 points, the total points is 5y.
So 2x + 5y = 125. Substitute one of the equations into the other to solve for the variables.
x + y = 49 becomes x = 49 - y. Substitute it.
2(49-y) + 5y = 125
98 - 2y + 5y = 125
98 + 3y = 125
3y = 27
y = 9
Substitute y = 9 back into the equation x = 49 - y to find x.
x = 49 - 9
x = 40
Let x represent the number of spaniels
4x + x = 30
combine like terms
5x = 30
divide each side by 5
x = 6
There are 6 spaniels.
~Hello there!
~1 gallon is 4 quarts.
~4 gallons is 16 quarts.
~So, 17 quarts would be bigger than 4 gallons.
