Answer:
x = 129
Step-by-step explanation:
Mathematically, the sum of interior angles of a polygon can be calculated using the formula;
(n-2)180
from the question given , n = 7 since the polygon has 7 sides
thus, we have it that
(7-2)180 = 5 * 180 = 900
Mathematically, by adding all the given interior angles, we can get the value of the total
We have this as;
900 = x + 131 + 119 + 125 + 133 + 125+ 138
900 = x + 771
x = 900-771
x = 129
Answer:
First, in standard notation, we must define our zero.
In this case, would make sense to define the zero in the surface of the water.
(below is a number line so you can see the process to think this)
Then if the whale is swimming 60ft bellow the surface of the water, then the first position of the whale is:
-60
Now the whale goes up 30ft, then the new position of the whale is:
-60ft + 30ft = -30ft.
The correct option is A:
The equation is -60 + 30 = -30. The whale is 30 feet below the water's surface.
(you wrote that the equation was equal to +30 instead of -30 in the option A, i supposed that it was a typo)
Answer:
the ratio of teaspoons of sugar to one large coffee is 3: 1
Step-by-step explanation:
The computation of the ratio of sugar teaspoons to one large coffee is as follows:
Sugar teaspoons = 2 + 1 = 3
And, the one large coffee = 1
So, based on the above information
The ratio between them is
= 3:1
= 3 to 1
hence, the ratio of teaspoons of sugar to one large coffee is 3: 1
