Step-by-step explanation:

because it is 40 cents for 1 bar so 40 plus 40 is 80 so minus 80 cents is 4.00 dollars

Answer:

two unequal, complex roots

Step-by-step explanation:

Rewrite this quadratic as a^2 + 3a - 7 = 0.  The coefficients are {1, 3, -7}.  The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.

Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.

Answer:

Sunrise $450 Bright Eyes $475

Step-by-step explanation:

Let x= number of days

Sunrise:

(25 + 85x)= total cost

(25+85(5))= $450

Bright Eyes:

(95x)= total cost

(95(5))= $475

The Bright eyes hotel would be more cost efficient than the Sunrise hotel.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Sunrise, a bed-and-breakfast hotel, that charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night.

The total cost for 5 nights at Sunrise hotel would be -

C(s) = 25 + 85 x 5 = $450

The total cost for 5 nights at Bright eyes hotel would be -

C(b) = 95 x 5 = $475

Therefore, the Bright eyes hotel would be more cost efficient than the Sunrise hotel.

Answer:

3x^2=81

x²=81/3

x=√27=3√3

Step-by-step explanation:

3x²=81

With this we have to square root both sides to find the value of x.

[tex] \sqrt{3 {x}^{2} } = \sqrt{81} [/tex]

So the x will cancel the square root sign so;

[tex]3x = \sqrt{81} [/tex]

And now we have to find the square root of 81 which is 9, because when we multiply 9 by 9 we are going to be get 81 so the square of 9 is 81 and the square root of 81 is 9

So;

[tex]3x = 9[/tex]

And then we divide both sides by 3 to find the value of x ;

[tex] \frac{3x}{3} = \frac{9}{3} [/tex]

[tex]x = \frac{9}{3} [/tex]

[tex]x = 3[/tex]

5(f-1)(f+13).

Measure of angle s:

Sum all angles of triangle is = 180 degrees

So,

31 + 58 + x = 180

x = 180 - 31 - 58

x  = 91

Measure of angle s: 91 degrees

Answer:

Step-by-step explanation:

The function C has the greatest initial value, and the function B has the greatest rate of change

A linear function is a function whose value changes at a constant rate.

A linear function is represented as:

[tex]y = mx + c[/tex]

Where

The initial value of function A is 0.

This is so because y = 0, when x = 0

The initial value of function B is -1

This is so because the value of function y = 3x - 1 is -1, when x = 0

From the graph, the initial value of function C is 2

Hence, the function C has the greatest initial value

Rate of change is calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, the rate of change of function A is calculated as follows:

[tex]m = \frac{5 - 0}{2-0}[/tex]

[tex]m = \frac{5 }{2}[/tex]

[tex]m = 2.5[/tex]

The rate of change of function A is 2.5

The rate of change of function B is 3.

The rate of change of function C is calculated as follows:

[tex]m = \frac{3 - 2}{3-0}[/tex]

[tex]m = \frac{1}{3}[/tex]

The rate of change of function C is 1/3

Hence, the function B has the greatest rate of change

Answer:

x = 39

Step-by-step explanation:

∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.

2x - 14 + 26 = 90

2x + 12 = 90

2x = 78

Answer:

34 ounces

Step-by-step explanation:

Here is the full question

Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle?

Let b = total ounces in the bottle

the equation that can be derived from this question is :

0.2 x b = 6.8

To find b, divide both sides by 0.2

b = 6.8 / 0.2 = 34 ounces

Hi there!

So what we need to do here is this...

Multiply -3/4  with there own parentheses and multiply 2 with it’s own parentthese also.

[tex]- \frac{3}{4} x 5p = 3 \frac{3}{4} p[/tex]

[tex]-\frac{3}{4} x 12 = 9[/tex]

Then do the second parenthese...

[tex]2x8=16[/tex]

[tex]2x - \frac{1}{4} = \frac{1}{2}p[/tex]

Add them like this...

[tex]( 3 \frac{3}{4}p + 9 ) + ( 16 -\frac{1}{2}p )[/tex]

Simplflied it again.../ since 3 3/4 and 1/2 both have p, add them...

[tex]3 \frac{3}{4} + - \frac{1}{2}p=3 \frac{1}{4}p[/tex]

Add the rest:

[tex]3 \frac{1}{4}p+9+16[/tex]

9(x + 4) = 54 ( divide both sides by 9 )
