Jason's making punch by mixing 1/2 cup of orange juice and 1/5 cup of mango juice. He wants to mix the orange juice and mango ju

Korolek [52]

Answer:

Orange juice cups = 15

Mango juice cups = 6

Step-by-step explanation:

$\text{Fraction of orange cup used in one punch = }\frac{1}{2}\\\\\text{Fraction of mango cup used in one punch = }\frac{1}{5}\\\\\text{Now, to calculate the ratio : lcm of (2,5) = 10}\\\\So, Orange : Mango = \frac{1}{2}\times 10 :\frac{1}{5}\times 10=5:2\\\\\text{Now, required no. of orange juice cups = }\frac{\text{Orange cup ratio}}{\text{Sum of ratios}}\times 21\\\\=\frac{5}{7}\times 21=15\thinspace cups$

$\text{Now, required no. of mango juice cups = }\frac{\text{Mango cup ratio}}{\text{Sum of ratios}}\times 21\\\\=\frac{2}{7}\times 21=6\thinspace cups$

Hence, No. of Orange juice cups needed to make 21 cups = 15 and no. of Mango juice cups needed to make 21 cups = 6

The solutions of the equation y? - 6x + 4 = 0 can be written as a+ Vb.

antoniya [11.8K]

Answer:

a = 3

b = 2

Step-by-step explanation:

(x - 3)² - 9 + 7 = 0

(x - 3)² - 2 = 0

x - 3 = ± √2

x = 3 ± √2

And they want the answer in the formula so a = 2 and b = 2

Somebody please help me on this?! What is the correct postulate or theorem for this one..

IRINA_888 [86]

Answer:

Segment Addition Postulate

Step-by-step explanation:

In geometry, the Segment Addition Postulate states that given 2 points A and C(in this case S and O), a third point B(in this case R) lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Meaning for R to lie on the line SO;

SR + RO must be equal to SO

Someone help please! Determine the intercept of the line that passes through the following points

storchak [24]

Answer:

x: (-5.0)

y: (0, -17.5)

Step-by-step explanation:

The x-intercept of the line is when y=0. In the table is the point (-5,0). This is the x-intercept.

To find the y-intercept, find when x=0. Write an equation for the table in y=mx + b. Find the slope between two points first.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{7-0}{-7--5} =\frac{7}{-7+5}=-\frac{7}{2} = -3.5$

The slope is -3.5. So the equation is

y - 7 = -3.5(x--7)

y - 7 = -3.5 (x+7)

y - 7 = -3.5x - 24.5

y = 3.5x - 17.5

Since it is in y=mx+b, b= -17.5 and this is the y-intercept.
