Answer:F=−20d+1500

Step-by-step explanation:he amount of filling used to make each dumpling is constant, so we're dealing with a linear relationship.

We could write the desired formula in slope-intercept form: F=\greenD md+\maroonD bF=md+b. In this form, \greenD mm gives us the slope of the graph of the function and \maroonD bb gives us the yy-intercept. Our goal is to find the values of \greenD mm and \maroonD bb and substitute them into this formula.

Hint #22 / 3

We know that each dumpling Dominik makes decreases the filling remaining by 2020 grams, so the slope \greenD mm is \greenD{-20}−20, and our function looks like F=\greenD{-20}d+\maroonD bF=−20d+b.

We also know that Dominik has 15001500 grams of filling initially, so the yy-intercept \maroonD{b}b is \maroonD{1500}1500.

Hint #33 / 3

Since \greenD{m}=\greenD{-20}m=−20 and \maroonD{b}=\maroonD{1500}b=1500, the desired formula is:

The function's formula for the grams F of filling remaining as a function of d, the number of dumplings Dominik makes, is given by:F(d) = 1500 - 20d

To derive this formula, we start by considering the total amount of filling Dominik has, which is 1500 grams. Each dumpling uses 20 grams of filling. Therefore, if Dominik makes d dumplings, he will have used 20d grams of filling. To find the remaining filling, we subtract the amount used from the total amount initially available:

[tex]\[ F(d) = \text{Total filling} - (\text{Filling per dumpling} \times \text{Number of dumplings}) \] \[ F(d) = 1500 - (20 \times d) \] \[ F(d) = 1500 - 20d \][/tex]

This function gives us the amount of filling, in grams, that remains after Dominik has made d dumplings.

Look at the picture.

Use the Pythagorean theorem to calculate x:

[tex]x^2=2^2+4^2\\\\x^2=4+16\\\\x^2=20\to x=\sqrt{20}\approx4.47\ cm[/tex]

[tex]A_1=\dfrac{8+6}{2}\cdot4=14\cdot2=28\ cm^2\\\\A_2=3\cdot6=18\ cm^2\\\\A_3=3\cdot4.47=13.41\ cm^2\\\\A=4A_1+2A_2+2A_3\\\\A=4\cdot28+2\cdot18+2\cdot13.41=174.82\ cm^2\approx175\ cm^2\\\\1mL\to1cm^2[/tex]

Answer:

Yes they are proportional!

The factors of 28 that we can use in these fractions are 4 and 7.  To find if these are proportional, just simplify 8/28.  To do so divide the numerator (top) and the denominator (bottom) both by 4...

8/28 / 4 = 4/7

Now that you have both with the same denominator, you can evaluate if 3/7 and 4/7 are proportional.  In this case they are.

3/17 = x/544

If x=96 then there are 96 grams of zinc.

The amount of zinc that contains in the jar will be 96 grams based on the given ratio.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Suppose the amount of zinc is Z while the copper is C.

The ratio Z/C = 3/17

And, C = 544

Z/544 = 3/17

Z = (3/17)544 = 96 grams.

Hence "The amount of zinc that contains in the jar will be 96 grams based on the given ratio".

Answer: hot dog = $1.75

Step-by-step explanation:

Let h represent hot dogs and c represent bags of chips.

Customer 1: 4h + 2c = 9.00  →  3(4h + 2c = 9.00)  →  12h + 6c =  27.00

Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75)  → -10h - 6c = -23.50

                                                                                       2h        =    3.50

                                                                                      ÷2               ÷2    

                                                                                        h        =    1.75

Final answer:

The cost of one hot dog is determined to be $1.75.

Explanation:

To find the cost of a hot dog, we will use the information given in two different customer purchases to set up a system of linear equations. Let's define H as the cost of one hot dog and C as the cost of a bag of chips. The first customer buys 4 hot dogs and 2 bags of chips for $9.00, which gives us the first equation:

4H + 2C = 9.00 ...(1)

The second customer buys 5 hot dogs and 3 bags of chips for $11.75, which provides us with the second equation:

5H + 3C = 11.75 ...(2)

With two equations, we can solve for H by either substitution or elimination. Let's multiply equation (1) by 3 and equation (2) by 2 to eliminate C:  

Subtracting equation (4) from equation (3) gives us:

2H = 3.50

And dividing both sides by 2:

H = 1.75

Therefore, the cost of one hot dog is $1.75.

Answer:

79.38 miles per hour

Step-by-step explanation:

average speed =  miles covered / hours

= 515.97 / 6.5

=  79.38

Answer:    79.38 miles per hour

Step-by-step explanation:

Given : Distance covered by rally car race course = 515.97 miles

Time taken to complete the course by winning car = 6.5 hours

The average speed of the winning car = ( Distance covered by rally car race course) ÷  (Time taken to complete the course by winning car)

= (515.97)÷ (6.5) miles per hour

= 79.38 miles per hour

Hence, the average speed of the winning car =  79.38 miles per hour.

Here, x represents the number of 20-pound boxes and y represents the number of 30 pound boxes.

As per the given condition: Vince loads 10 boxes into his truck.Some of the boxes weigh 20 pounds, and some weigh 30 pounds and the total weight of the boxes is 280 pounds.

⇒ x+ y =10                      .....[1]

and

20x+30y = 280               .....[2]

Multiply  equation [1]  by 20 we get;

[tex]20(x+y) = 20\cdot 10[/tex]

Using distributive property: [tex]a\cdot(b+c) = a\cdot b + a\cdot c[/tex]

20x + 20y = 200                   ....[3]

Subtract equation [3] from [2] we get;

[tex]20x+30y-20x-20y = 280-200[/tex]

Combine like terms;

10y = 80

Divide both sides by 10 we get;

y = 8

Substitute this y value in equation [1] we get;

x + 8 = 10

Subtract 8 from both sides we get;

x + 8 -8 =10-8

Simplify:

x = 2

Therefore, the pairs of equation are:  x+ y =10 and 20x+30y = 280

Vince has the number of 20-pound boxes is, 2 and the number of 30 pound boxes is, 8

Answer:

[tex]5\sqrt{3}[/tex] inches long is the other leg

Step-by-step explanation:

Given the statement: If the hypotenuse of a right triangle is 10 inches long and one of its legs is 5 inches long.

Hypotenuse side = 10 inches

Let length of other leg be x.

Pythagoras theorem states that in a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Then; by definition of Pythagoras theorem;

[tex]{\text}(Hypotenuse)^2 = (5)^2 + x^2[/tex]

[tex](10)^2 = 5^2 + x^2[/tex]

[tex]100 = 25 + x^2[/tex]

Subtract 25 on both sides we get;

[tex]100-25= 25 + x^2-25[/tex]

Simplify:

[tex]75 = x^2[/tex]

Simplify:

[tex]x = \sqrt{75} = 5\sqrt{3}[/tex] inches

Therefore, the sides of other leg is [tex]5\sqrt{3}[/tex] inches

Final answer:

Using the Pythagorean theorem, and knowing the length of the hypotenuse (10 inches) and one leg (5 inches), we calculate the other leg to be approximately 8.66 inches in length.

Explanation:

The question involves finding the length of the other leg of a right triangle when the lengths of the hypotenuse and one leg are known. By applying the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). The theorem is usually written as a² + b² = c².

In this case, the hypotenuse (c) is given as 10 inches, and one leg (a) is 5 inches. To find the length of the other leg (b), rearrange the Pythagorean theorem as b² = c² - a². Substituting the known values gives us b² = 10² - 5² leading to b² = 100 - 25. Therefore, b² = 75. Taking the square root of both sides to solve for b gives us b = √75 which simplifies to approximately 8.66 inches when rounded to two decimal places.

Thus, the length of the other leg in the right triangle is approximately 8.66 inches.

[tex]\$4701.80[/tex]

Step-by-step explanation:

Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate and she gets a loan payoff of 60 months,

We know that,

[tex]\text{PV of annuity}=P\left[\dfrac{1-(1+r)^{-n}}{r}\right][/tex]

Where,

PV = Present value of annuity = 25000,

r = rate of interest of each period = [tex]\dfrac{7}{12}[/tex]% monthly

n = number of periods = 60 months,

Putting the values,

[tex]\Rightarrow 25000=P\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right][/tex]

[tex]\Rightarrow P=\dfrac{25000}{\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]}[/tex]

[tex]\Rightarrow P=\$495.03[/tex]

Hence total amount paid is,

[tex]=495.03\times 60=\$29,701.80[/tex]

Therefore interest amount is,

[tex]=29,701.80-25,000=\$4701.80[/tex]

Answer: The value of x = 90°

and the value of y = 43°

Step-by-step explanation:

Since we have given that

In ΔABC,

∠B=∠C=47°

As we know that "Sum of all three angles of a triangle is 180° ".

So, it becomes,

[tex]\angle A+\angle B+\angle C=180\textdegree\\\\\angle A+47\textdegree+47\textdegree=180\textdegree\\\\\angle A+94\textdegree=180\textdegree\\\\\angle A=180\textdegree-94\textdegree\\\\\angle A=86\textdegree\\\\So,\\\\y=\frac{86}{2}=43\textdegree[/tex]

Similarly,

Now, in ΔABD,

[tex]\angle A+\angle B+\angle ADB=180\textdegree\\\\43\textdegree+47\textdegree+\angle ADB=180\textdegree\\\\90\textdegree+\angle ADB=180\textdegree\\\\\angle ADB=180\textdegree-90\textdegree\\\\\angle ADB=90\textdegree[/tex]

Hence, the value of x = 90°

2. You know the -x as an argument of the function will flip the curve left-to-right, so only C and D are potential choices. One way to resolve the ambiguity is to see what the function value is for x=0. You find they are the same:

... f(0) = root(3)(0 -1) = g(0) = root(3)(-0-1) = root(3)(-1)

Only graph C has the two curves crossing at x=0.

___

f(x) = root(3)(x -1) is a shift to the right of the parent function root(3)(x).

Replacing x by -x reflects that function across the y-axis, so what was a shift to the right now becomes a shift to the left, as seen in graph C.
