Solution:

As, it is given that school's lemonade is $10\%$ lemon juice by volume, and the rest is sugar water.

School's lemonade which is Sugar water= (100-10)=90 % volume

Let total volume of Lemonade (Lemon Juice + Sugar Water) = x liter

Volume percent of Lemon Juice = \frac{\text{Percentage of Volume of Lemonade}}{\text{Percent of Volume of Sugar solution}}\times 100

= \frac{10}{90}\times 100=\frac{100}{9}%

Let , number of liters of lemon juice must be added to 20 liters of sugar water to make the school's lemonade= x liter

To find , number of liters  of lemon juice must be added to 20 liters of sugar water to make the school's lemonade, we will use the following formula:

→Volume percent of Lemon Juice = \frac{\text{ Volume of Lemonade}}{\text{ Volume of Sugar solution}}\times 100

= \frac{100}{9}=\frac{x}{20}\times 100\\\\ x=\frac{20}{9}

= 2.23 Liter(Approx)

The percentage of lemon in the juice is 10%
The percentage of water sugar is (100-10)=90%
The quantity of lemon in 20 liters of sugar water will be:
amount=(percentage of lemon)/(percentage of sugar water)×(amount of sugar water)
=10/90×20
=2 2/9 liters

Linear equation is equation in which each term has at max one degree. The function that can represent the given graph is y=2.0769x + 1.5.

<h3>What is linear equation?</h3>

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on Cartesian plane with axes of those variables, give a straight line.

For the given graph the equation can be written as, y = mx+c, this is because the graph is a line which means the relationship is linear. Therefore, the equation can be written as,

y = mx + c

Now, there are two points that are on the line and the coordinates of this points are,

A = (4, 9.5)

B = (7.25, 16)

Further the slope of the equation is,

m = (16-9.5) / (7.25 - 4) = 2.0769

Since c is the y-intercept of the graph, therefore, the value of c is 1.5.

Thus, the function that can represent the given graph is y=2.0769x + 1.5.

Answer:

angle C = 78

angle D = 108

Step-by-step explanation:

the measure of angle A is 102

To find the measure of angle C

let Angle C be x

102 + x = 180 (linear pair)

x = 180 -102

x = 78

angle C = 78

angle B = 78 (vertically opposite angles are equal)

angle D = 108 (vertically opposite angles are equal)
