What I need to know is how to find x and y values by representing the answers in simplest radical form where necessary

Maru [420]

Answer:

x = 0.6623

y = 8

Image is attached for refernce of my solution

Step-by-step explanation:

In Δ DEF

By applying pythagoras theoram,

DE = $\sqrt{EF^{2} - DF^{2} }$

= $\sqrt{17^{2} - 15^{2} } = \sqrt{289 - 225} = \sqrt{64} =8$

∴ DE = 8

In Δ ABC

BC = y = 12 sin 30° = 6

AC = $\sqrt{3}$ + DE + x = $\sqrt{3}$ + 8 + x = 12 cos 30°

⇒ 9.73 + x = 10.39

The cost of fabric (y) is directly proportional to he length is yards (x). If 5 yards of fabric cost $14, which equation models

marta [7]

Answer:

5x = 14

Step-by-step explanation:

If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.

The green would take 4 and the blue would take 16 times respectivly. I did it by finding the volumes of the cups in terms of pi, then dividing it by the volume of the sink.

Step-by-step explanation:

So the volume of the whole half sphere is 512pi.

Now we have to find the volumes of the cup.

Equation: $\pi r^2h$
