How would i calculate 1.9 minus 11/12?
Levart [38]

Answer:

59/ 60

Step-by-step explanation:

1.9 can be expressed as 19/10

Thus, our equation becomes

19/10 -11/12.

This becomes (228 -110) / 120

= 118 / 120

Simplify by 2 to get

59/60

Total consumption of fruit juice in a particular country in 2006 was about 1.86 billion
hram777 [196]

Answer:

Step-by-step explanation:

Kindly check explanation

Step-by-step explanation:

The population of that country in 2006 was 500 million. What was the average number of

gallons of fruit juice consumed per person in the country in 2006? Use pencil and paper. Using the per

person amount from this problem, about how many gallons would your class consume?

Total consumption in 2006 = 2.11 billion gallons (2,110,000,000)

Population of country in 2006 = 500,000,000

Average number of gallons of fruit juice consumed per person in the country in 2006:

Total consumption / total population

2,110,000,000 / 500,000,000

= 4.22 gallons per person

Number of gallons class will consume :

Assume number of students in class = 15

Hence, class consumption equals:

Average consumption per person × number of students in class :

4.22 × 15 = 63.3 gallons

How do u do b??????????
horrorfan [7]

the assumption being that the first machine is the one on the left-hand-side and the second is the one on the right-hand-side.

the input goes to the 1st machine and the output of that goes to the 2nd machine.

a)

if she uses and input of 6 on the 2nd one, the result will be 6² - 6  = 30, if we feed that to the 1st one the result will be √( 30 - 5) = √25 = 5, so, simply having the machines swap places will work to get a final output of 5.

b)

clearly we can never get an output  of -5 from a square root, however we can from the quadratic one, the 2nd machine/equation.

let's check something, we need a -5 on the 2nd, so

\bf \underset{final~out put}{\stackrel{y}{-5}}=x^2-6\implies 1=x^2\implies \sqrt{1}=x\implies 1=x

so if we use a "1" as the output on the first machine, we should be able to find out what input we need, let's do that.

\bf \underset{first~out put}{\stackrel{y}{1}}=\sqrt{x-5}\implies 1^2=x-5\implies 1=x-5\implies 6=x

so if we use an input of 6 on the first machine, we should be able to get a -5 as final output from the 2nd machine.

\bf \stackrel{first~machine}{y=\sqrt{\boxed{6}-5}}\implies y=\sqrt{1}\implies y=1 \\\\\\ \stackrel{second~machine}{y = \boxed{1}^2-6}\implies y = 1-6\implies y = -5

The diameter of a circular chip is doubled to use in a new board game. The area of the new chip will be
nikitadnepr [17]

Answer: A_2=\frac{\pi(2D)^{2}}{4}


Step-by-step explanation:

1. You have the following formula for calculate the area of the original circular chip:

A_1=\frac{\pi(D)^{2}}{4}

Where D is the diameter of the circle.

2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:

A_2=\frac{\pi(2D)^{2}}{4}
