Answer:

Steak burgers = $4.50

Fries = $2.25

Step-by-step explanation:

Steak burgers = x; fries = y

-2 (3x + 2y = $18)

3  (2x + 3y = $15.75)

-6x - 4y = -36

6x + 9y = 47.25

5y = 11.25

÷5    ÷5

y = $2.25

3x + 2y = 18

3x + 2( 2.25 ) = 18

3x + 4.5 = 18

     -4.5   -4.5

3x = 13.5

÷3     ÷3

x = $4.50

Step-by-step explanation:

f(2) = 6        (what multiplies 2 to equal 6?)*2 = 6

It seems like x gets multiplied by three. Let's check the next one:

f(-1) = -3

Ah ha! We were right. Let's check one more time:

2 * 3 = 6

-1 * 3 = -3

f(x) just means what is f when x is any number. This function that we covered above is: f(x) = 3x

If w = 10 units, x = 5 units, and y = 6 units, what is the surface area of the figure? Round your answer to the nearest tenth.
Figure is composed of a right square pyramid on top of a square prism. The sides of the square pyramid are equal to the sides of the square prism, the length and width of the square prism is w, the height of the square prism is x, and the height of the square pyramid, which forms a right angle with the center, is y.
A) 656.2 units2
B) 400 units2
C) 256.2 units2
D) 456.2 units2

Answers

Answer:

456.2 units², so answer d

Step-by-step explanation:

The area of the square base is ...

 base area = w² = (10 units)² = 100 units²

The lateral area is 4 times the area of one rectangular face:

 lateral area = 4wx = 4(10 units)(5 units) = 200 units²

The area of one triangular face is half the product of its base length (w) and its slant height (h). The latter is found using the Pythagorean theorem:

 h² = y² +(w/2)² = (6 units)² +((10 units)/2)² = 61 units²

 h = √61 units

So, the area of 4 triangles is ...

 area of triangular faces = 4(1/2)wh = 2(10 units)(√61 units) ≈ 156.2 units²

Now we have the areas of the parts, so we can add them together to get the total surface area:

 surface area = base area + lateral area + area of triangular faces

 = 100 units² + 200 units² + 156.2 units²

 surface area = 456.2 units²

He percentage of defective chips produced each hour by oven A has a mean of 33. 56 and a standard deviation of 5. 20. The percentage of defective chips produced each hour by oven B has a mean of 32. 44 and a standard deviation of 3. 78. The hourly differences in percentages for oven A minus oven B have a mean of 1. 11 and a standard deviation of 4. 28. Does there appear to be a difference between oven A and oven B with respect to the mean percentages of defective chips produced

Answers

Using the z-distribution, as we have the standard deviation for the population, it is found that it does not appear that there is a difference.

What are the hypothesis tested?

At the null hypothesis, it is tested that there is no difference, that is, the mean of the distribution of the differences is of 0, hence:

[tex]H_0: \mu = 0[/tex]

At the alternative hypothesis, it is tested if there is a difference, hence:

[tex]H_1: \mu \neq 0[/tex]

What is the test statistic?

It is given by:

[tex]z = \frac{\overline{x} - \mu}{s}[/tex]

In which:

[tex]\overline{x}[/tex] is the mean of the distribution of differences.[tex]\mu = 0[/tex] is the value tested at the null hypothesis.s is the standard error.

In this problem, the parameters are as follows: [tex]\mu = 1.11, s = 4.28[/tex].

Hence:

[tex]z = \frac{\overline{x} - \mu}{s}[/tex]

[tex]z = \frac{1.11 - 0}{4.28}[/tex]

[tex]z = 0.26[/tex]

What is the decision?

Considering a two-tailed test, as we are testing if the mean is different of a value, with a standard significance level of 0.05, the critical value is of [tex]|z^{\ast}| = 1.96[/tex].

Since the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis, that is, it does not appear that there is a difference.

Answers

The range of acceptable values for production to continue working of the company without stoppage is 15.85 to 16.15.

What is the range of acceptable values?

Range is the area of fluctuation between the upper and lower limit. The range of the acceptable values is all the values between the upper and lower limit.

Here, a company manufactures 16-oz boxes of cereal.  Now, this boxes are randomly weighted to ensure the correct amount.

As the discrepancy in weight is more than 0.15 oz then the production of the company is stopped.

To proper functioning of the company without stoppage, the limit of the production should be with in 0.15 oz.

The company produce, 16-oz boxes of cereal and the disperancy is 0.15 oz. Thus the value of the lower limit will be,

[tex]L=16-0.15\\L=15.85\rm \; oz[/tex]

The value of the upper limit will be,

[tex]U=16+0.15\\U=16.15\rm \; oz[/tex]

Thus, the range will be {15.85-16.15 oz}

Hence, the range of acceptable values for production to continue working of the company without stoppage is 15.85 to 16.15.

Find the value of x, y, and z in the parallelogram below.

Answers

Answer:

x=7

y=-54

z=82

Step-by-step explanation:

Hello! Let me see if I can help you!

I can't see the picture very clearly, but since it is a parallelogram, there are two sides that are parallel. That means that the opposite angles are equal to each other.

102=(-2y-6)

Solve for y:

6+102=-2y

y is equal to -54

For x and z its different because there needs to be a second equation:

(10x+8)=(z-4) is not satisfactory because it has two variables in it. Thus, we need another equation.

(z-4)+102=180 (This we know because a straight line is 180 degrees, and the two angles added together are a straight line.)

Solve for z, 180-102=z-4, z is equal to 82.

Finally, using (10x+8)=(z-4) use the already solved value for z, and then solve for x. X is equal to 7 when you solve that way.

Again I can't see the entire thing, but this is how I would try. Hope it works!

Answer: Aye aye, cap'in

Step-by-step explanation:

So we start off with our base value, 1/3 gallons.

We are trying to find how many gallons we have eaten, so we do 1/3*1/3, since we need to find what is 1/3rd of that gallon.

For reference, if you wanted to find how much is left over, we multiply by 2/3 since 1-1/3 = 2/3, so there are 2/3 of the 1/3rd gallons left. Not important for solving this problem, but it might help you understand why we decided to multiply by 1/3.

1/3 * 1/3 = 1/9

Our answer is 1/9.

Answers

Answer:

Thoma is 11

Step-by-step explanation:

We can call Aldo 'a' and Thoma 't'.

"Aldo's age is three times Thoma's age" can be written algebraically as a = 3t

"The sum of their ages is 44" can be written as a + t = 44

Because we know that a = 3t, we can substitute this into the equation a + t = 44 to get 3t + t = 44. This can be simplified to 4t = 44. If we divide both sides by four we get t = 11. This means that Thoma is 11.

In your answer, give the measures of angles X, Y, and Z, and explain how you calculated each one.

Answers

Answer:

ok

Step-by-step explanation:

x:

X is adjacent to the 75 angle so x + 75 need to be 180.

180 - 75 = 105

x = 105

z:

Z is on opposite across outside corners from X so it will be the same thing.

z = 105

y:

Y is adjacent to Z so Y + Z must equal 180.

Z = 105

y + 105 = 180

y = 75

What is compound interest?

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\left(1+\dfrac{R}{n\times100}\right)^{nt}[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly.

Put this values in the above formula as,

For the four years, the monthly payment is,

[tex]m=\dfrac{11422.6348}{12\times4}\\m=237.97[/tex]

The monthly payment of unsubsidized loan is $237.97.

The monthly payment of subsidized loan is $202.80.

The difference between the unsubsidized and subsidized loan monthly payment is,

Step-by-step explanation:

Answer: 105/20 in decimal = 5.25

Step-by-step explanation: The fraction bar means "divided by" in the fraction 105/20, where 105 is the numerator and 20 is the denominator. As a result, the fraction 105/20 can be written as "105 divided by 20" or "105 20."

We discovered that 105/20 in decimal form is: 105 20 = 5.25 when we divided 105 by 20.

As a result, 105/20 has a decimal form of 5.25.
