Solve the triangle, plssss help me:(

Answer:

The total cost of meal is $65.34

Step-by-step explanation:

Price of the meal = $54

Sales tax on meal = 6%

Tip given= 15% on pre-tax amount

We need to find total cost of meal.

First finding sales tax amount:

We need to calculate 6% of 54



So, the sales tax would be $3.24

Now, we need to find tip amount

We will find 15% of 54



So, the tip given would be $8.1

The total cost of meal = Price of meal + Sales Tax + Tip

                                      = 54+3.24+8.1

                                      = 65.34

So, the total cost of meal is $65.34

Answer: A prime is (-4,-5). B prime is (0,-1). C prime is (1,-5)

Step-by-step explanation:

You can either count three units to the right and from there 7 units down from each point to find its prime, or alternatively from each original x,y value of each point you can add 3 to the x value (because it wants you to move 3 units to the right and subtract 7 from the y value (because it wants you to move down 7 units).

Answer:

It is not a solution.

Step-by-step explanation:

y = 2x - 4

2 = 2(3) - 4

2 = 6 - 4

2 = 2

The point is a solution to the first equation.

3x + 2y = 8

3(3) + 2(2) = 8

9 + 4 = 8

11 ≠ 8

The point is only a solution for one equation. It is not a solution to the system.

Hope this helps.

Answer:

The confidence interval will be given by:

[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.

For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In the context of this problems:

It means that the sampling distributions of the sample mean of 500 components will be approximated normal, with mean 200,000 and standard deviation [tex]s = \frac{1000}{\sqrt{500}} = 44.72[/tex]

To build the confidence interval:

The confidence interval for the average length of life of the electronic components they produced will be given by:

[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.

For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]

Answer:75

Step-by-step explanation:

180-64 gives you the angle not labelled which is 116 then to work out size of angle formula is 180(n-2) n being sides so 180(6-2) = 720 so 720 minus all the angles = 75 I think lol

Answer:

x = 75

Step-by-step explanation:

180-64 = 116

Since this is a hexagon (6 vertices), the angles all add up to 720

116 + 121 + 155 + x + 90 + 163 = 720

x + 645 = 720

x = 75

[tex]f(x,y)=x+y\\[/tex]

constrain:

[tex]g(x,y)=x^2+y^2 = 7\\h(x,y)=x^3+y^3=10[/tex]

Partial derivatives:

[tex]f_{x}=1\\f_{y} =1 \\g_{x}=2x \\g_{y}=2y\\h_{x}=3x^2 \\h_{y}=3y^2[/tex]

Lagrange multiplier:

[tex]grad(f)=a*grad(g)+b*grad(h)\\[/tex]

[tex]\left[\begin{array}{ccc}1\\1\end{array}\right]=a\left[\begin{array}{ccc}2x\\2y\end{array}\right]+b\left[\begin{array}{ccc}3x^2\\3y^2\end{array}\right][/tex]

4 equations:

[tex]1=2ax+3bx^2\\1=2ay+3by^2\\x^2+y^2=7\\x^3+y^3=10[/tex]

By solving:

[tex]a=4/9\\b=-2/27\\x+y=4[/tex]

Second mathod:

Solve for x^2+y^2 = 7, x^3+y^3=10 first:

[tex]x=\frac{1}{2} -\frac{\sqrt{13}}{2} \ or \ y=\frac{1}{2} +\frac{\sqrt{13}}{2} \\x=\frac{1}{2} +\frac{\sqrt{13}}{2} \ or \ y=\frac{1}{2} -\frac{\sqrt{13}}{2} \\x+y=-5\ or\ 1 \or\ 4[/tex]

The maximum is 4

Amount Avery paid: 32,000-12,000-6,000 = 15,000

Divide portion she paid by total cost:

15,000/33,000

Simplify to 15/33

Multiply the amount the boat was sold for by her portion:

25,300 x 15/33 = 11,500

Subtract the amount she got from the amount she paid:

15,000 - 11,500 = 3,500

She lost $3,500

Answer: 5.04x[tex]10^{4}[/tex] particles

in your situation is choose : A

Step-by-step explanation:

the volume of the living room is 1,400[tex]m^{3}[/tex], and there are 3.6 x [tex]10^{1}[/tex] particles of dust / [tex]m^{3}[/tex]

we will convert the room volume to scientific notation = 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex]

then, the total number of particles will be the product of the two numbers, which is 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex] times 3.6 x [tex]10^{1}[/tex] particles/[tex]m^{3}[/tex] = 5.04x[tex]10^{4}[/tex] particles

Answer:

the answer can be 1.667 or -4

Answer and Step-by-step explanation:

The independent variable is m, and the dependent variable is h.

This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.

With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

Step-by-step explanation:

Divide it into a 3-by-3 square and a right triangle with legs that are 3 and 4.

area of square = 3² = 9 units²

area of triangle = ½×4×3 = 6 units²

total area = 9+6 = 15 units²
