X is greater than y by 12 and Z is less than y by 8. If the ratio of x:z is 9:4. What is the ratio of value of Z?
kakasveta [241]

Answer:

B) 16 . . . . the value of Z

Step-by-step explanation:

The problem statement tells us that ...

... x = y +12

... z = y - 8

Then x - z = (y +12) -(y -8) = 20.

In ratio units, we have ...

... x:z = 9:4

The difference of these in ratio units is 9-4 = 5, so each ratio unit must stand for 20/5 = 4 units of X, Y, or Z. Hence ...

... Z = 4·4

... Z = 16

_____

<em>Check by finding the other values</em>

... X = 9·4 = 36

... Y = X -12 = 24 = Z +8 . . . . yes

Help me please! <br><br> a = 3, b = 5, and c = 7. What is m&amp;Bº to the nearest tenth?
Anastaziya [24]

Answer: m∡B°=38,2°.

Step-by-step explanation:

a=3,  b=5,  c=7  ∡B°=?

b^2=a^2+c^2-2*a*ccosB^0\\2*a*c*cosB^0=a^2+c^2-b^2\\cosB^0=\frac{a^2+c^2-b^2}{2*a*c} \\cosB^0=\frac{3^2+7^2-5^2}{2*3*7} \\cosB^0=\frac{9+49-25}{2*3*7} \\cosB^0=\frac{33}{42} \\cosB^0=\frac{11}{14}\\

m∡B°=arccos(\frac{11}{14})

m∡B°≈38,2°.

Good luck!
