Answer: 10+ 10 = 20

1+1= 2

Step-by-step explanation:

The number of Nickels and Dimes out of the 13 coins are respectively; 4 Nickels and 9 Dimes

We are told that we have 13 coins and they are all nickels and dimes and they sum up to $1.00.

Let N represent nickels.

Let D represent dimes

Thus;

N + D = 13

D = 13 - N

From conversion tables of nickels and dime to dollars, we can generate the equation;

$0.05N + $0.10D = $1.00

Plug in 13 - N for D to get;

$0.05N + $0.10(13 - N) = $1.00

$0.05N + $1.30 - $0.10N = $1.10

0.20 = 0.05N

N = 0.20/0.05

N = 4

D = 13 - 4

D = 9

Step-by-step explanation:

You start with $50, and if $20 is spent on food then you have 50-20= $30 remaining for games.

Games are $2 each, and you have $30 for games, so we can divide the amount of money you have by the amount of money required for each game to find out how many games you can play:

30/2 = 15

Therefore after spending $20 on food, you are able to play 15 games with the remaining money.

Using Vieta's Theorem the value of c = 72.

Suppose we have a quadratic equation, in the following format:

ax² + bx + c, were a, b, and c are constant.

The roots are p and q.

As, The Theorem states that:

p + q= -b/a

pq= c/a

We have given the polynomial  x²-17x+c=0

So, a= 1, b= -17

Since the difference of the solutions is 1, we have that:

p -q= 1

p = 1+ q

Now, using p + q= -b/a

1 + q + q= -(-17)/1

2q +1 = 17

2q= 16

q= 16/2

q= 8

The points of solution that are obtained for the system of linear equations 6x - 3y = 66 and x + 3y = -10 are (8,6).

The substitution methods given are incomplete and incorrect.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

6x - 3y = 66....(1)

x + 3y = -10....(2)

Simplify the equation (1) and (2) by adding -

6x + x - 3y + 3y = 66 - 10

7x = 56

x = 8

Substituting the value of x = 8 in equation (1) -

6x - 3y = 66

6(8) - 3y = 66

48 - 3y = 66

-3y = 66 - 48

-3y = 18

y = -6

The approximate lateral area of the cone is solved to be 314 cm²

From the question we get that:

The area of the circular base of a cone is 25π cm²

25π cm² =  πr²

the slant height of the cone is four times the radius of the cone

L = 4r

Lateral area of the cone

= πrl square units.

solving for r

25π cm² =  πr²

r² = 25

r = 5

solving for the lateral area of the cone

Answer: To find the distance traveled during one ride, we need to find the circumference of the circle formed by the Ferris wheel's rotation. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.

Given that the diameter of the Ferris wheel is 54 feet, we can find the radius by dividing the diameter by 2:

r = 54 / 2 = 27

Therefore, the circumference of the circle is:

C = 2πr = 2 * 3.14 * 27 = 170.68

To find the distance traveled during one ride, we need to multiply the circumference by the number of revolutions:

distance = C * 17 = 170.68 * 17 = 2,908.76

Rounded to the nearest whole number, the distance traveled during one ride is 2909 feet.

2.73

Answer:

To multiply 1.3 by 2.1, we need to use the distributive property of multiplication, which states that:

a × (b + c) = a × b + a × c

Using this property, we can break down 2.1 as the sum of 2 and 0.1:

1.3 × 2.1 = 1.3 × (2 + 0.1)

= 1.3 × 2 + 1.3 × 0.1

= 2.6 + 0.13

= 2.73

Therefore, 1.3 multiplied by 2.1 equals 2.73.

The statement is always true that if |a| > 0, then the graph of f(x) = a∛x rises as x increases. The solution is obtained by graphing the function.

What is graphing of a function?

Drawing the graph of an applicable function is the process of graphing a function. While graphing simple functions like direct, quadratic,etc. is fairly easy, complex functions like rational, logarithmic,etc. bear some complexity and an understanding of certain fine ideas. Every point on the curve will satisfy the function equation if the curve represents the function.

We are given a function f(x) = a∛x.

We know that |a| will always be greater than or equal to 0 irrespective of "a" being positive or negative.

If |a| > 0, then the graph of f(x) = a∛x is a vertical stretch of the graph of g(x) = ∛x.

The graph for g(x) = ∛x is shown below.

Since, g(x) = ∛x rises as x increases, the same must be true for f(x) = a∛x.

Hence, if |a| > 0, then the graph of f(x) = a∛x rises as x increases.

The line of the inequality will be dotted and the origin is the solution to the inequality. Hence option A is the correct option.

Inequalities are mathematical expressions in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is replaced by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given the equation of the inequality is y <2/3 x +1.

The inequality contains a less than symbol.

If an inequality contains less than or equal/ greater than or equal sign, then the line of the inequality will be solid.

If an inequality contains less than or greater than, then the line of the inequality will be dotted.

The line of the given inequality will be dotted.

Now putting x = 0, y = 0 in the inequality:

0< (2/3×0) + 1

0 < 1 true.

A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign divides the variables 3x + 5 and 14. The relationship between the two sentences on either side of a letter is explained by a mathematical formula. There is frequently only one variable, which also serves as the symbol. for instance, 2x - 4 = 2.

given

The equation's fundamental form is:

4p(x-h) = (y-k) (y-k)

The vertex is at 2 (h,k).

P is the separation between the vertex and the directrix or focus. Between the two is where the vertex is located.

Directrix: x=2, focus: (1, -4).

Vertex at the perpendicular midpoint of (1.5, -4)

Parabola opens left because it faces the focus and moves away from the directrix. This implies that p will be negative. P would be positive if the parabola opened to the right. p = -0.5

Putting this together:

4(-0.5)(x-1.5) = (y-(-4))2

-2(x-1.5) = (y+4)2

-2(x-1.5) = y2 + 8y + 16

x - 1.5 = (-1/2)(y2 + 8y + 16)

x = (-1/2)y2 - 4y - 8 + 1.5
