Answer:

25% sugar syrup means in a mixture of 100g sugar syrup, sugar should be 25g

so, when sugar is 25g , mixture is 100g

when sugar is 1g, mixture is 100/25 = 4g

when sugar is 15g, mixture is 15*4 =60g

So, amount of water to be added=60-15= 45g

Answer: I can provide you with the data in tabular format if you want to create the graph with the provided data.

Airtime (min) | Prepaid costs | Contract costs

0 | 41.67 | 108.42

10 | 54.67 | 108.42

20 | 67.67 | 108.42

30 | 80.67 | 108.42

40 | 93.67 | 108.42

50 | 102.14 | 108.42

60 | 114.64 | 108.42

This table shows the airtime (in minutes) used, and the corresponding costs for both prepaid and contract call plans. The prepaid costs are calculated using the formula: R41.67 + R1.30 x airtime used, whereas the contract costs are fixed at R108.42.

It's worth noting that the costs for the contract call plan is fixed and doesn't change with the airtime used, while for the prepaid plan the costs increase as the airtime increases.

Answer:

x = 2, y = 7

Step-by-step explanation:

y - 3x = 1    |*2

2y - x = 12

2y - 6x = 2

2y - x = 12   | - Ist equation

2y-x-2y+6x = 12-2

5x = 10

x = 2

Insert x to first equation:

y - 3*2 = 1

y = 7

Answer:

13

Step-by-step explanation:

Since a = 3,  10 x 3 = 30

5c = 5 x 2 = 10

2c = 2 x 2

Now we have 30 - 3 - 10 - 4

30 - 3 = 27 - 10 = 17 - 4 = 13

13 is our total

Answer:

[tex] \sf \: 10a - 3 - 5c - 2c = 13[/tex]

Step-by-step explanation:

Given expression,

→ 10a - 3 - 5c - 2c

Now we have to use,

→ a = 3

→ c = 2

Let's solve the expression,

→ 10a - 3 - 5c - 2c

→ 10(3) - 3 - 5(2) - 2(2)

→ 30 - 3 - 10 - 4

→ 30 - 3 - 14

→ 30 - 17

→ 13 => final value

Therefore, the answer is 13.

1728 is the cubic of the number 12.

Cube of given number = [tex]12^{3}[/tex] which is equal to 1728.

The cubes are made up of values that are obtained by multiplying integers by themselves three or four times. The cube's original number can be found by raising any natural number to the power of three.

Cubes are the numbers that are produced when an integer is multiplied by itself three times. We can find cubes for any number, whether it be an integer or a fraction. In order for the cube of a whole number (x) to produce a perfect cube, the cube root of x3 must equal x. The procedure of locating cubes is thus the opposite of locating the cube root.

The formula for finding the base of an isosceles triangle is Base = 2 x (Area) / (Height)

An isosceles triangle is a particular kind of triangle in which the lengths of the two sides are equal. This indicates that the two base angles' lengths are similar (congruent means that they are of the same measure). The third side is referred to as the base, and its opposite angle is referred to as the vertex angle. The legs are the two sides that are of equal length.

The formula for finding the base of an isosceles triangle is - Base = 2 * (Area) / (Height). Where the Area is the total area of the triangle, and "Height" is the height of the triangle as measured from the base to the apex (or the point opposite the base).

Draci sets up a room for a banquet with 6 tables.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=15x+7. Where:

m= the slope.

b= the constant term that represents the y-intercept.

The problem is a literal math question, that you can convert into a linear equation. Where:

x= number of tables

y= number of chairs

From the information of the question, you can write:

y=mx+b, where:

y= total number of chairs= 54

So, 25 minutes after Baxter began filling the tank, the volume of water in the tank is 255 gallons.

A linear equation can be used to model the situation where water is flowing into a tank at a constant rate. The equation would be in the form:

V = 55 + 8t

Where V is the volume of water in the tank (in gallons), t is the time (in minutes) that has passed since Baxter began filling the tank, and 55 and 8 are the y-intercept and slope respectively

To find the volume of water in the tank 25 minutes after Baxter began filling it, you would substitute 25 for t in the equation above:

V = 55 + 8(25) = 55 + 200 = 255 gallons

So, 25 minutes after Baxter began filling the tank, the volume of water in the tank is 255 gallons.

The zeros of function f(x) = x² -x - 2 are: x = 2 and x = -1

Consider given polynomial function  f(x)=x² -x - 2

As we know the zeros of a function are nothing but the values of the variable of the function that makes the function value equal to 0.

To find the zeros of function f(x), we need to equate f(x) to zero then solve it for x.

⇒ f(x) = 0

⇒ x² -x - 2 = 0

using the Quadratic Formula where

a = 1, b = -1, and c = -2

[tex]\Rightarrow x=\frac{-b\pm \sqrt{b^2 -4ac} }{2a}\\\\\\ \Rightarrow x = \frac{1\pm \sqrt{9} }{2}\\\\\\\Rightarrow x = \frac{1\pm 3 }{2}[/tex]

The point (-1,3) would be located at the point (3,-1) after a 270 degree counterclockwise rotation about the point (1,0).

To rotate a point in a 2D space, we can use the rotation matrix formula:

[x'] = [cos(Ф) -sin(Ф)][x]

[y'] [sin(Ф) cos(Ф)][y]

Where x' and y' are the coordinates of the point after rotation, x and y are the coordinates of the point before rotation, and theta is the angle of rotation in radians.

In this case, the point to be rotated is (-1,3) and the point of rotation is (1,0). The angle of rotation is 270 degrees, which is equivalent to 3/2π radians.

Plugging in the values:

[x'] = [cos(3/2π) -sin(3/2π)][-1]

[y'] [sin(3/2π) cos(3/2π)][3]

[x'] = [0 1][-1]

[y'] [-1 0][3]

x' = 3 and y' = -1

The number of cups of each ingredient Kwame and Olivia could have used is 6 cups and 10 cups respectively.

In mathematics, a combination is a selection of items from a collection, such that the order of selection does not matter. For example, the combination of three fruits from a basket containing apples, oranges, and bananas would be the set {apple, orange, banana}, {apple, banana, orange}, {orange, apple, banana}, {orange, banana, apple}, {banana, apple, orange}, and {banana, orange, apple}. The number of possible combinations is often represented using the combination formula, which is often written as "nCr", where "n" is the total number of items in the collection.

It's not possible to give an exact example of the number of cups of each ingredient each person used, as there are infinitely many ways that Kwame and Olivia could have combined orange juice and mango juice to make 12 and 20 cups respectively.

However, one example of the number of cups of each ingredient each person could have used is:

Kwame: 6 cups orange juice, 6 cups mango juice Olivia: 10 cups orange juice, 10 cups mango juice

This satisfies the constraints that Kwame uses less orange juice than Olivia and his orange-mango juice tastes more like oranges than hers does.
