Answer:
x ≈ 31.0°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanx = 
= 
, then
x = 
( ) ≈ 31.0° ( to 1 dec. place )
Answer:
44.8
Step-by-step explanation:
cos α = adjacent leg/hypotenuse
cos 48° = 30/x
x = 30/(cos 48°) = 44.8
The equation of the line that passes through (3, −2) and is perpendicular to y = (3/4)x + 6 will be y = -(4/3)x + 2. Then the correct option is B.
<h3>What is the equation of a perpendicular line?</h3>
Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. Or if the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given below.
y = (3/4)x + 1/3
The slope of the line is 3/4. Then the slope of the perpendicular line will be
Slope = - 1 / (3/4)
Slope = - 4 / 3
Then the equation of the line will be
y = -(4/3)x + D
The line is passing through (3, -2), then the value of D will be
-2 = (-4/3) × 3 + D
-2 = - 4 + D
D = 2
The equation of the line that passes through (3, −2) and is perpendicular to y = (3/4)x + 6 will be y = -(4/3)x + 2. Then the correct option is B.

Answer:
830 calories
Step-by-step explanation:
The number of calories in a muffin is directly proportional to the amount of sugar in the muffin.
Let the number of muffins be N and the amount of sugar in the muffin be A. This means that:
N α A
=> N = kA
where k = constant of proportionality
A 200 calorie muffin has 500 grams of sugar.
This implies that:
200 = k * 500
=> k = 200 / 500 = 2/5
The constant of proportionality is 2/5.
The number of calories in a muffin with 2075 grams of sugar is:
N = 2/5 * 2075
N = 830 calories
There are 830 calories.
