the Royal fruit company produces two types of fruit drinks. the first type is 20% pure juice,the second type is 100% pure fruit
skad [1K]

30 pints of first type and 130 pints of second type drinks must be used to make the mixture.

<em><u>Explanation</u></em>

Lets assume, the amount of first type drink is x pints.

As the total amount of the mixture is 160 pints, so the amount of second type drink = (160-x) pints.

The first type is 20% pure juice, the second type is 100% pure fruit juice and the mixture is 85% pure fruit juice. So the equation will be .....

0.20x+1.00(160-x)= 0.85*160\\ \\ 0.20x+160-x=136\\ \\ -0.80x= -24\\ \\ x=\frac{-24}{-0.80}=30

So, the amount of first type drink is 30 pints and the amount of second type drink is (160-30)pints =130 pints.

Pls help me on this question :-

Answer:

We conclude that the rule for the table in terms of x and y is:

  • y = 3x+2

Step-by-step explanation:

The table indicates that there is constant change in the x and y values, meaning the table represents the linear function the graph of which would be a straight line.

We know the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept.

Taking two points

  • (-2, -4)
  • (-1, -1)

Finding the slope between (-2, -4) and (-1, -1)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-2,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-1\right)

m=\frac{-1-\left(-4\right)}{-1-\left(-2\right)}

m=3

We know that the y-intercept can be determined by setting x = 0 and finding the corresponding y-value.

Taking another point (0, 2) from the table.

It means at x = 0, y = 2.

Thus, the y-intercept b = 2

Using the slope-intercept form of the linear line function

y = mx+b

substituting m = 3 and b = 2

y = 3x+2

Therefore, we conclude that the rule for the table in terms of x and y is:

  • y = 3x+2

Trina invited 60 people to her party and 42 said they would attend. What percent of people said they were NOT able to attend? Pl
Llana [10]
1. simplify 42/60 to 7/10 (42/60 divided by 2 is 21/30, 21/30 divided by 3 is 7/10)
2. if 10 x 10 = 100 than 7 x 10 = 70 so that would make it 70/100 which is 70%
so 70% is the answer

Hope this helps ;)
