The ratio given is 4:5 so you do 5divided by 20 which is 4 and multiply 4 and 4 and get 16 so your ratio is 16:20
Answer:
the ratio of 6:5 can be expressed as 6/5
Answer:
B.) 73°
Step-by-step explanation:
To find m<A, first you must find it's supplementary angle. In order to do this, you must determine the missing interior angle. We'll call the missing angle x
A pentagon has 540°. Add up the known angles.
96°+118°+115°+104°+x = 540°
433°+x = 540°
x = 107°
Now that we know the value of x, we can find the m<A. Supplementary angles are two angles that add up to 180°, which is a flat line. We can see in the diagram that m<a + 107° is a flat line, meaning m<a + 107° = 180°
Solve accordingly.
m<a + 107° = 180°
m<a = 73°
A)
The formula for direct variation is written as Y = KX, where k is the direct variation you need to solve for.
Y is the total amount raised and X would be the number of attendees:
100 = K5
Divide both sides by 5:
K = 100/5
K = 20
B. The constant of variation is K which is 20
C) Using the formula from A: y = kx, replace k with 20 and x with 60 and solve for y:
y = 20 * 60
y = 1200
The total is: $1,200
2. A relationship is proportional when the ratio is a constant number.The relationship is non proportional when the ratio varies between the different values.
