Answer:

Step-by-step explanation:
Total number of coins in the bag = 5 + 4 + 5 + 2 = 16 coins
Number of nickels in the bag = 4
We have to find the probability that Marissa draws a nickels from the bag.
Probability is defined as the ratio of Number of "Favorable Outcomes" to "Total number of possible outcomes"
In this case total number of possible outcomes is the total number of coins which is 16.
Favorable/Desires outcome is drawing a Nickle from the bag which are 4 in number. So, number of favorable outcomes is 4
Therefore, the probability that she will draw a nickel = 
Answer:
130
Step-by-step explanation:
From the FIQURE of the question, we can see that line "e" is parallel to line "f" then we can say (2x + 18)=( 4x - 14)
Then we can collect like terms
2x-4x= -14-18
-2x=-32
The negatives cancelled out we have
x = 16
From the question, At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees
Angle on a straight line is 180° then we can calculate "y" as
y = 180 - (4x - 14)
= 180-4x+14
= 180+14-4x
But x= 16, then substitute we have
= 180 +14 - 14(16)
= 130
Hence, the value of y is 130

The answer is 2300 because the climbing rate is 100 bacteria per hour. so times 100 and 13 and u get 1300 and u have to add that to the a 1000
