Answer:

62 oz

Step-by-step explanation:

Let the volume of water to add be x so that the new volume will be (30+x) oz

The new concentration is now 15%, expressed in decimal as 0.15 and it is found by dividing the initial concentration by new volume

\frac {0.46*30}{30+x}=0.15\\\frac {0.46*30}{0.15}=30+x\\92=30+x\\x=62

The volume of water to add is equal to 62 oz

gladu [14]

Answer:

6x²y²

Step-by-step explanation:

6: 1 2 3 6

18: 1 2 3 6 9 18

36: 1 2 3 4 6 9 12 18 36

the common factor for 6 18 and 36 are

1 2 3 6

x² = x × x

y³ = y × y × y

x³ = x × x × x

y³ = y × y × y

x³ = x × x × x

y² = y × y

the common factor are for x and y are

x² y²

Multiply the GCF of the numerical part 6 and the GCF of the variable part x² y² to get 6x² y²

Please help for D, E and F
Phantasy [73]
D) 24/65 because it represents the number of players with 1-5 years of experience out of the overall total interviewed.

E) 3/11 because out of the eleven rookies, only three of them were under 200 lbs.

F) out of the 8 that reported to be under 200 pounds, only 3 were rookies, so the probability is 3/8

Find the greatest common factor and the least common multiple of 16 and 20. The prime factorizations of each number are given.
kykrilka [37]

Answer:

GCF 4, LCM 80

Step-by-step explanation:

Since both 16 and 20 have two 2s as factor, their greatest common factor is 4.

The LCM is found by multiplying all of the remaining factors by the LCM:

16 still has (2 x 2), 20 still has (5), times the GCF (4)  so 2 x 2 x 5 x 4 = 80.
