Answer:
<h2>x = 12</h2>
Step-by-step explanation:
ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:
We have AD = 16, DC = x, DB = 9. Substitute:
<em>cross multiply</em>
Answer = 84
Step-by-step explanation :
Area = b • h
14 = b
6 = h
14 • 6 = 84
If m varies directly with x, then that means that you have to find the slope. To make it easier, m = y-variable, and x = x-variable.
Because you are trying to find your constant of variation (another word for slope, rate of change, etc.), the change of y over the change of x is your equation. in other words, divide your m variable by x.
When m = 60 and x = 6, you can set it up. 60 / 6 = k; and k = 10 when solved. Since 10 is not one of the answer choices listed in your answer key, I believe that your answer is NONE OF THE ABOVE.
I hoped this helped you.
Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a = 
a = 
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,
AD × DC = BD²
b × 4 = 9²
b = 
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
Answer:
box X with 126 sq. cm. i hope this helps :)
Step-by-step explanation:
okay so we have box X which is 6 * 3 * 7 = 126
then we have box Y which is 11 * 2 * 5 = 110
so box X will hold more
