Answer:
Triangle C
Step-by-step explanation:
Triangle A: All sides have length 9 cm.
<em>By </em><em>SSS</em><em> this is a </em><em>unique</em><em> triangle.
</em>
Triangle B: Two sides have length 10 cm, and the included angle measures 60°.
<em>By </em><em>SAS</em><em> this is a </em><em>unique</em><em> triangle.
</em>
Triangle C: Two angles measure 50°.
<em>This gives us at most </em><em>SS Similarity</em><em>, so we do not have a unique triangle. The triangle sides can be any length. </em><em>This is not unique</em><em>.
</em>
<em>
</em>
Triangle D: Base has length 8 cm, and base angles measure 45°. Which triangle is not a unique triangle?
<em>
This gives us </em><em>ASA</em><em>, so we have a </em><em>unique</em><em> triangle.
</em>
Answer: Triangle C
Answer:
true
Step-by-step explanation:
Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
You would do 1/4 and get the answer plus 3/8s answer
I have to form a couple of equations in order to solve it.
let the amount of soybean in the mixture be x and that of cornmeal be y
Step-by-step explanation:
x+y = 280
y = 280 - x
x*(14/100) + y*(7/100) = 280*(12/100)
Multiplying the whole equation by 100;
14x + 7y = 3360
in this equation,put y = 280 - x
14x +7 (280-x) = 3360
14x +1960 - 7x = 3360
14x - 7x = 3360 - 1960
7x = 1400
x = 200lbs
y = 280 - x
= 280 - 200
= 80 lbs
Inorder to make a 280lbs mixture having 12% protein, we should mix 200lbs of soyabean and 80 lbs of cornmeal
