The correct answer would be 17/50 because you have to make the 2 bottom numbers the same.

16/25 and -3/10 must become 34/50 and -15/50. and since 15/50 is negitive this is basically a subtraction problem. so 34/50 - 15/50 = 19/50.and 19 cant divide so the answer is 19/50.

Answer:

x° is 66°  

Step-by-step explanation:

From the given diagram, we have;

∠JIH = 105° Given

∠IDJ = 39° Given

Therefore, we have;

∠JID and ∠JIH are supplementary angles, by the sum of angles on a straight line

∴ ∠JID + ∠JIH = 180° by definition of supplementary angles

∠JID + 105° = 180° by substitution property

∠JID = 180° - 105° = 75° by angle subtraction postulate

∠JID = 75°

∠IDJ + ∠JID + ∠IJD = 180° by the sum of interior angles of a triangle

∠IJD = 180° - (∠IDJ + ∠JID)  = 180° - (39° + 75°) = 66° angle subtraction postulate

∠IJD = 66°

∠x° ≅ ∠IJD, by vertically opposite angles

∴ ∠x° = ∠IJD = 66° by the definition of congruency

∠x° = 66°

The elevation​ E, in​ meters, above sea level at which the boiling point of a certain liquid is t degrees Celsius is given by th
const2013 [10]
For T = 89.5 degrees C:
E(t) = 1100(90 - 89.5) + 520(90 - 89.5)^2= 1100(0.5) + 520(0.5)^2= 550 + 130= 680 m
For T = 90 degrees C:
E(t) = 1100(90 - 90) + 520(90 - 90)^2= 0 + 0= 0 m (meaning that boiling point is 90 degrees C at ground level)

In the game of Pick-A-Ball without replacement, there are 10 colored balls: 3 red, 4 white, and 3 blue. The balls have been plac
Margarita [4]

Answer:A)0.27

B)0.78

Step-by-step explanation:

This is the probability of picking 2balls of same color.

P(RR)+Pr(WW)+Pr(BB)

3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=

24/90=4/15=0.27

B)if the first ball is not returned, then there are 9 balls left.

Then probability of same color will be

PrB+PrW+PrR

2/9+3/9+2/9=

7/9=0.78
