Answer:

she bought 3 chicken wings

Step-by-step explanation:

8c = 10.4 --> where c is the cost of a chicken wing

c = 10.4 divided by 8

= 1.3

xc = 3.9 (x = number of chicken wings)

1.3x = 3.9

x = 3.9 divided by 1.3

which is 3

Answer:

[tex]\sqrt{20} \text{ or } 2\sqrt{5}[/tex]

Step-by-step explanation:

So in this question we want to use the Pythagorean Theorem which essentially gives us a relationship between the sides of a triangle and is as follows: [tex]a^2+b^2=c^2[/tex]

In this formula the "a" and "b" represent the base and the height and "c" represents the hypotenuse of the triangle

The order in which you assign "a" and "b" do not matter, so let's just say that: [tex]a=4\ \text{and}\ c=6[/tex]

Although it is important that you assign the hypotenuse to "c".

So plugging in known values we have the equation:

[tex]4^2 +b^2=6^2[/tex]

Square the values

[tex]16+b^2=36[/tex]

Subtract1 16 from both sides

[tex]b^2=20[/tex]

take the square root of both sides

[tex]b=\sqrt{20}[/tex]

This "b" represents our other side, which we did not initially know, so this is our answer :)

You can simplify this further by separating the radical into: [tex]\sqrt{20} = \sqrt{4} * \sqrt{5} = 2\sqrt{5}[/tex]

The correct answer is D. the x- intercept of the given graph is (-1.75,0) and y - intercept is (0,3)

The x-intercept is the location where a line's graph crosses the x-axis.

The y-intercept is the location where a line's graph crosses the y-axis.

The shapes of these points are (x,0) and (0,y), respectively.

Utilize the fact that all x-intercepts have a y-value of zero and all y-intercepts have an x-value of zero to get the x- and y-intercepts algebraically. Set x=0 and find the equivalent y value to calculate the y -intercept. Set y=0 and then figure out the matching x value to discover the x -intercept.

The transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

The equations of the functions are given as

f(x) = |x|

g(x) = |x + 3|

The above implies that

g(x) = f(x + 3)

When a function is shifted to the left by h units, it is represented as

g(x) = f(x + h)

This means that

h = 3

So, the transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

Step-by-step explanation:

16 3/4 days in total.

that are (16×4 + 3)/4 = 67/4 days.

he has taken

1 3/4 = (1×4 + 3)/4 = 7/4 days

4 2/3 = (4×3 + 2)/3 = 14/3 days

2 1/6 = (2×6 + 1) = 13/6 days

to be able to add abd subtract them directly, we need to bring all fractions to the same denominator.

we have 3, 4, 6 : the smallest common multiple is 12 (can be divided without remainder by 3, 4 and 6).

we need to multiply each fraction by a fitting n/n factor to bring the denominators to 12 and keep the overall value of the fraction unchanged.

67/4 = 67/4 × 3/3 = 201/12

7/4 = 7/4 × 3/3 = 21/12

14/3 = 14/3 × 4/4 = 56/12

13/6 = 13/6 × 2/2 = 26/12

the remaining vacation time is

201/12 - 21/12 - 56/12 - 26/12 = 98/12 = 49/6

49/6 = 8 and remainder 1 = (8×6 + 1)/6 = 8 1/6 days

The number of toppings where the cost of each pizza would be equal is 5.

The first step is to formulate an equation that represents the cost of each type of pizza.

Total cost = price of cheese pizza + (price per topping x number of toppings)

Cost of pizza A = $10 + $1.50t

Cost of pizza B = $12.50 + t

When the cost of both pizzas are equal, the above equations would be equal to each other.

$10 + $1.50t = $12.50 + t

To determine the value of t, take the following steps:

Combine similar terms: 1.50t - t = $12.50 - $10

Add similar terms = 0.50t = 2,50

Divide both sides by 0.50 = t = 2.50 / 0.50

t = 5

Step-by-step explanation:

The equation of line can be written as, y = 2/3x + 2

Given,

The points, (x, y) = (-3, 0)

Slope = 2/3

Equation of a line, y = mx + c

Where, m is the slope and c is the y-intercept.

Here, m is 2/3.

The point at the x-intercept has co-ordinates : (-3, 0)

Where, x is -3 and y is 0.

So, substitute the values in equation:

y = mx + c

0 = 2/3 × (-3) + c

0 = -2 + c

c = 2

Answer:

The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

Step-by-step explanation:

It is given that a line perpendicular to YX passes through the point (3,-8).​

Now,

The slope of the line perpendicular to the line YX is 1.

=> y = x

So, Slope = 1

Furthermore, the slope of the required line can be written as -1.

So, the required line can be written in slope-intercept form as;

=>  y = − x + c

It is further given that the line passes through the point (3,2);

So, after putting all the value in the above-mentioned equation, we get;

=> 2 = − 3 + c

=> c = 5

So, x + y = 5
