Answer: Each brick woukd weigh 772 troy ounces
Step-by-step explanation:
A. 9
B. 24
C. 6
D. 16
Step-by-step explanation:
Given ratios are;
A. 2 : 3 = 6 : x
Product of mean = Product of extreme

Dividing both sides by 2

B. 4 : 7 = x : 42
Product of mean = Product of extreme

Dividing both sides by 7

C. 2x : 48 = 3 : 12
Product of extreme = Product of mean

Dividing both sides by 24

D. 12 : 15 = x : 20
Product of mean = Product of extreme

Dividing both sides by 15

(C)
fraction of the marbles now in the bag is blue.

What is a fraction?</h3>
- A fraction is a portion of a whole or, more broadly, any number of equal parts.
- In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters.
- A common, vulgar, or simple fraction that consists of a numerator above a line and a non-zero denominator below that line.
- Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals.
To find what fraction of the marbles now in the bag is blue:
- Important information is that immediately before the last step blue marbles formed
from the marble in the bag. - That means that there were
blue and
other marbles, for some
. - When we double the number of blue marbles, there will be
blue and
other marbles. - Hence, blue marbles now form
all marbles in the bag.
Therefore, (C)

Complete question:
A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only 1 / 3 of the marbles in the bag are blue. Then yellow marbles are added to the bag until only 1 / 5 of the marbles in the bag are blue. Finally, the number of blue marbles in the bag is doubled. What fraction of the marbles now in the bag are blue?
(A) 1/5
(B) 1/4
(C) 1/3
(D) 2/5
(E) 1/2
Answer: The product of (-4)(-8) is 32. Multiply two negatives makes it positive. So just think of it as 4 times 8. Which is 32.
Average rate of change is the slope of two coordinate points or values.
Therefore,
Given values are :
(1960,668) and (1970,760)
Slope = (760 - 668)/(1970 - 1960)
Slope = 92/10
Rate of change will be 9.2 gallons/passenger
