4x4 is 16 its 16 you got it right
Answer:
1/3125 or, 5^-5
Step-by-step explanation:
5^-1 = blank * 5^4
1/5/625= blank or, 5^-1/5^4=blank
blank=1/3125 5^-5=blank
Answer:
.19m+70=c
Step-by-step explanation:
.19m represents $0.19 per minute
+70 represents the fixed monthly fee
so you'd multiply the minutes by 19cents and add the $70 to find cost per month
1) Answer: x = 9
<u>Step-by-step explanation:</u>
Same Side Interior Angles are supplementary
15 + 5x + 14x - 6 = 180
19x + 9 = 180
19x = 171
x = 9
***************************************************************
2) Answer: x = 9
<u>Step-by-step explanation:</u>
Corresponding Angles are congruent
13x - 7 = 11x + 11
2x = 18
x = 9
***************************************************************
3) Answer: x = -10
<u>Step-by-step explanation:</u>
Alternating Interior Angles are congruent
90 = x + 100
-10 = x
***************************************************************
3) Answer: x = 7
<u>Step-by-step explanation:</u>
Alternating Exterior Angles are congruent
17x + 1 = 120
17x = 119
x = 7
Answer: (A) 30%
Step-by-step explanation:
Given : The probability that a bird will lay an egg =0.75
The probability that the egg will hatch =0.50
Now, the probability that the egg will lay an egg and hatch = 
Also,The probability that the chick will be eaten by a snake before it fledges =0.20
Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80
Now, the probability that a parent will have progeny that survive to adulthood will be :-
Hence, the probability that a parent will have progeny that survive to adulthood = 30%
