Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets. To make this, he combines some 80/20 mixture with some pure water in each 5-gallon bucket. How many gallons of pure water does Manny add to each 5-gallon bucket? Express your answer as a decimal to the nearest hundredth.

Answers

Answer:

1.25 gallons of pure water

Step-by-step explanation:

Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets.

0.80 d + 0.20w = 15 gallon

Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets.

0.60d + 0.40w = 5 gallon

0.80 d + 0.20w = 15 ....... Equation 1

0.60d + 0.40w = 5 ......….. Equation 2

Using elimination method

Multiply Equation 1 with 0.60

Multiply Equation 2 with 0.80

We eliminate d

0.80 d + 0.20w = 15 × 0.6

0.60d + 0.40w = 5 × 0.8

=

0.48d + 1.2w = 9....... Equation 4

0.48d + 3.2w = 4..... Equation 5

Subtract Equation 5 from 4

= - 2.0w = -5

w = -5/-2

w = 2.5 gallons.

Hence: 2.5 gallons/2

= 1.25 gallons.

Therefore, Manny adds 1.25 gallons of pure water.

which table has a constant of proportionality between Y and X of 1/5?

Answers

Answer:

B

Step-by-step explanation:

From the table B has a constant of proportionality between y and x of 1/5.

We need to find which table has a constant of proportionality between y and x of 1/5.

What is constant of proportionality?

Constant of proportionality is the constant value of the ratio between two proportional quantities.

The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate.

Now, k=y/x

From table A:

k=4/5 ÷ 2

=2/5

k=14/5 ÷ 7

=2/5

k=24/5 ÷ 12

=2/5

From table B:

k=8/5 ÷ 8

=1/5

k=9/5 ÷ 9

=1/5

k=2/10 =1/5

From table C:

k=16/5 ÷ 3

=16/15

k=26/5 ÷ 5

=26/25

k=36/5 ÷ 7

=36/35

Therefore, from the table B has a constant of proportionality between y and x of 1/5.

Find three consecutive odd integers such that the sum of the first and the third is 70. Find the integers.

Answers

Answer:

33, 35, 37

Step-by-step explanation:

Let the tree consecutive odd integers be x, x +2 and x + 4

According to the given information:

Sum of the first and the third is 70

[tex] \therefore x + x + 4 = 70\\\\

\therefore 2x = 70 - 4\\\\

\therefore 2x = 66\\\\

\therefore x = \frac{66}{2}\\\\

\therefore x = 33\\\\

\implies x + 2 = 33 + 2 = 35\\\\

\& \hspace{25 pt}x + 4 = 33 + 4 = 37\\\\[/tex]

Thus, the three consecutive odd integers are 33, 35 and 37.

Verification: 33 + 37 = 70

Find the equation of the line use exact numbers y =___ x + _____ PLEASE HELP

The equation of the graphed line, in slope-intercept form, is: y = -3x + 7.

How to Find the Equation of a Line in Slope-intercept Form?

To find the equation of the line that is given above, we need to find the slope of the line (m) and the y-intercept (b), then substitute the values into y = mx + b.

Find the slope:

Slope of a line (m) = change in y / change in x = rise/run

The line declines, so, the value of the slope would be negative.

Rise (change in y) = 3 units

Run (change in x) = 1 unit

Slope (m) = - (3 units/1 unit)

Slope (m) = -3

The y-intercept (b) would be the point where the line cuts the y-axis, which is: 7.

Y-intercept (b) = 7

Write the equation by substituting b = 7 and m = -3 into y = mx + b:

y = -3x + 7.

Thus, the equation, in slope-intercept form, is: y = -3x + 7.

Does John 1:3 teach that God created all matter? Answer the question by quoting that verse. The Curse of the Bambino(1) On December 26, 1919, the owner of the Boston Red Sox, Harry Frazee, made a decision that would haunt fans of the club for 86 years. He sold his best player, Babe Ruth, to the New York Yankees. This transaction marked the beginning of the "Curse of the Bambino." The Curse of the Bambino was the belief that, because the Red Sox sold Babe Ruth, they would never win another World Series.(2) Ruth helped the Red Sox win the World Series in 1915, 1916, and 1918. However, his demands for a higher salary and his poor attitude caused Frazee to look for a chance to trade him. He chose an offer from the Yankees to sell Ruth for cash.(3) Unfortunately for the Red Sox, Ruth would go on to become the greatest player in the history of the game. After purchasing Ruth, the Yankees would go on to become the most successful baseball club in history. They won their 26th World Series title in 2000.(4) However, the worst part of the curse was that the Red Sox came very close to winning the championship several times but suffered heartbreaking losses. For Sox fans, seeing their team suffer heartbreaking losses was worse than the fate of teams like the Chicago Cubs, who were usually too bad to even get close.(5) Finally, in 2004, Red Sox fans were rewarded for their loyalty. The Red Sox were able to defeat their rivals, the Yankees, to advance to the World Series. Then, they easily defeated the St. Louis Cardinals. While Red Sox fans suffered for 86 years, they would say that their victory in 2004 was sweeter because they had longed for it for so many years.Which of the following sentences should be added to the end of paragraph 1? A. On the other hand, fans of the Chicago Cubs believe in the "Curse of the Billy Goat." B. That day in 1919 would prove to be one of the most talked about days in the history of baseball. C. Furthermore, there were other teams that supposedly had curses, too. D. However, curses do not really exist, even if the fans are convinced that they do.Who ever has the right answer ill mark it as brainliest What is a company orchestra, and why are these orchestras helpful for both the companies and the workers?
