Answer:
x = 15°
y = 59°
Step-by-step explanation:
Angles at a right angle add up to 90°
41 + y = 90
y = 90 - 41
y = 59°
Angles in a triangle add up to 180°
41 + (2x - 9) + 7x + 13 = 180
41 + 13 - 9 + 2x + 7x = 180
45 + 9x = 180
9x = 180 - 45
9x = 135
x = 135/9
x = 15°
Answer:
Step-by-step explanation:
See the solution process below:
Explanation:
The slope-intercept form of a linear equation is: y =mx+b
Where m is the slope and b
is the y-intercept value.
We are given the slope in the problem so we can substitute
−5/6 for m in the formula.
And,
(0,6)
is the y-intercept so we can substitute
6
for
b
in the formula giving:
y
=
−

Answer:
Step-by-step explanation:
We are told that the average human heart beats 
times per day and there are 
days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.
Now we will solve this problem using exponent properties.
Our answer is in scientific notation we can represent it in standard form as 
times.
Therefore, average human heart beats in one year or 41975000 times.
