Answer:

64 cups of lemon juice

Explanation:

First, you can determine with the information provided the amount of cups of lemon needed to prepare sixteen cups of lemonade:

5 cups of lemonade→2 cups of lemon juice

16 cups of lemonade→x

x=(16*2)/5=6.4 cups of lemon juice

Now, you now that for sixteen cups that is the amount in a gallon you need 6.4 cups of lemon juice and you can use a rule of three to determine the amount needed for ten gallons of lemonade:

1 gallon of lemonade→6.4 cups of lemon juice

10 galons of lemonade→x

x=(10*6.4)/1=64 cups of lemon juice

According to this, the answer is that 64 cups of lemon juice are needed to make ten gallons of lemonade.

Answer:

[tex] 4\sqrt{10} [/tex]

Step-by-step explanation:

Perimeter of the rhombus, STAR, is the sum of the length of all it's 4 sides.

The coordinates of its vertices are given as,

S(-1, 2)

T(2, 3)

A(3, 0)

R(0, -1)

Length of each side can be calculated using the distance formula given as [tex] d = \sqrt{x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Find the length of each side ST, TA, AR, RS, using the above formula by plugging in the coordinate values (x, y) of each vertices.

[tex] ST = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

S(-1, 2) => (x1, y1)

T(2, 3) => (x2, y2)

[tex] ST = \sqrt{(2 -(-1))^2 + (3 - 2)^2} [/tex]

[tex] ST = \sqrt{(3)^2 + (1)^2} = \sqrt{9 + 1} = \sqrt{10} [/tex]

[tex] TA = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

T(2, 3) => (x1, y1)

A(3, 0) => (x2, y2)

[tex] TA = \sqrt{(3 - 2)^2 + (0 - 3)^2} [/tex]

[tex] TA = \sqrt{(1)^2 + (-3)^2} = \sqrt{1 + 9} = \sqrt{10} [/tex]

[tex] AR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

A(3, 0) => (x1, y1)

R(0, -1) => (x2, y2)

[tex] AR = \sqrt{(0 - 3)^2 + (-1 - 0)^2} [/tex]

[tex] AR = \sqrt{(-3)^2 + (-1)^2} = \sqrt{9 + 1} = \sqrt{10} [/tex]

[tex] RS = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

R(0, -1) => (x1, y1)

S(-1, 2) => (x2, y2)

[tex] RS = \sqrt{(-1 - 0)^2 + (2 -(-1))^2} [/tex]

[tex] RS = \sqrt{(-1)^2 + (3)^2} = \sqrt{1 + 9} = \sqrt{10} [/tex]

[tex] Perimeter = ST + TA + AR + RS [/tex]

[tex] Perimeter = \sqrt{10} + \sqrt{10} + \sqrt{10} + \sqrt{10} = 4\sqrt{10} [/tex]

Answer:

f = -3/4

Step-by-step explanation:

13f + 6 -f = -3

Combine like terms

12f +6 = -3

Subtract 6 from each side

12f+6-6 = -3-6

12f = -9

Divide each side by 12

12f/12 = -9/12

f = -3/4

Answer:

f= -3/4 or -0.75

Step-by-step explanation:

We are given the equation:

13f + 6 -f = -3

First, let's combine like terms. Subtract f from 13f.

(13f-f) + 6 = -3

12f + 6= -3

We want to find f. Therefore, we must isolate the variable on one side of the equation.

6 is being added to 12f. The inverse of addition is subtraction. Subtract 6 from both sides of the equation.

12f + 6 -6 = -3-6

12f= -3-6

12f= -9

f is being multiplied by 12. The inverse of multiplication is division. Divide both sides by 12.

12f/12= -9/12

f= -9/12

This fraction can be reduced. Both the numerator and denominator can be divided by 3.

f = (-9/3) / (12/3)

f= -3/4

f=-0.75

The solution to the equation is f= -3/4 or -0.75

Answer:

a.    [tex]T = 17s[/tex]

b.    [tex]D = 72cm[/tex]

Step-by-step explanation:

Given

Direct Variation

[tex]Distance(D)\ \alpha\ Time (T)[/tex]

D = 264 cm when T = 11 s

Calculating (a)

First, the constant of variation (k) as to be calculated;

Since, there exist a direct proportion; then,

[tex]D\ \alpha\ T[/tex]

[tex]D = kT[/tex]

Make k the subject of formula

[tex]k = \frac{D}{T}[/tex]

D = 264 cm when T = 11 s; So

[tex]k = \frac{264}{11}[/tex]

[tex]k = 24[/tex]

So: Solving for (a)

[tex]D = 408[/tex]

Substitute 408 for D and 24 for k in [tex]D = kT[/tex]

[tex]408 = 24 * T[/tex]

Divide both sides by 24

[tex]\frac{408}{24} = T[/tex]

[tex]T = \frac{408}{24}[/tex]

[tex]T = 17s[/tex]

Hence, time to move a distance of 408cm is 17s

Calculating (b)

[tex]T = 3[/tex]

Substitute 3 for T and 24 for k in [tex]D = kT[/tex]

[tex]D = 24 * 3[/tex]

[tex]D = 72cm[/tex]

Hence, distance covered in 3 seconds is 72cm

Answer:

5th degree polynomial

Step-by-step explanation:

The degree of a polynomial is the highest sum of the exponents in one term.

So we have the polynomial:

[tex]6xy^4-3x^3-4[/tex]

Calculate the degree of each term:

1st Term:

[tex]6xy^4[/tex]

This is the same as:

[tex]6x^1y^4[/tex]

So, our degree is 1+4=5.

2nd Term:

[tex]-3x^3[/tex]

There is only one variable. So, the degree is 3.

3rd Term:

[tex]-4[/tex]

This is the same as:

[tex]-4x^0[/tex]

So, this is a zeroth degree.

The largest degree is 5.

So, this is a fifth degree polynomial.

Notes:

To be more specific, this is a fifth degree trinomial.

Answer:

third degree

Step-by-step explanation:

it is a third degree polynomial because the equation is considered cubic. cubic means to the 3rd power. its cubic because there's three parts to the equation

Answer:

65000(1.02)^n.

Step-by-step explanation:

Salary = 65000(1.02)^n   where n is the number of years he has worked for the company.

So after one year he earns $6500* 1.02 and after 2 years $65000 * 1.02^2.

The exponential function represents Mark's salary is [tex]65000(1.02)^n.[/tex]

The mathematical expression f(x)=exp or e^x denotes the exponential function.

The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to complex numbers or adapted to other mathematical objects like matrices or Lie algebras.

Given that Mark just landed a great job as an engineer where he will make $65,000 a year. The company he will work for guarantees a 2% pay increase each year so its employees' salaries keep up with inflation. At the end of the first year, Mark will have made $65,000.

The exponential function for the salary will be written as:-

[tex]Salary = 65000(1.02)^n[/tex]  

where n is the number of years he has worked for the company.

So after one year, he earns $6500 x 1.02, and after 2 years $65000 x 1.02².

Therefore, the exponential function represents Mark's salary is [tex]65000(1.02)^n.[/tex]

Step-by-step explanation:

Answer:

The expression of density of the material with a density of 6 pound per pint in grams per liter (g/L) is 5756.75 g/L

Step-by-step explanation:

The density of the material is 6 pounds per pint of volume

The given conversion factors are;

1 pint (pt) = 2 cups (cups)

1 cup (cup) = 8 fluid ounces (fl oz)

Therefore;

2 cups (cups) = 2 × 8 fluid ounces = 16 fl oz

Also given;

1 fluid ounce = 29.574 mililiters (mL)

16 fl oz = 16 × 29.574 mL = 473.184 mL

1 liter (L) = 1000 mililiters (mL)

∴ 1 mL = 1/1000 L = 0.001 L

473.184 mL = 473.184 ×  0.001 L = 0.473184 L

1 pound (lb) = 0.454 kilograms (kg)

6 lb = 6 × 0.454 kg = 2.724 kg

1 kg = 1000 grams (g)

2.724 kg = 2.724 ×  1000 grams (g) = 2724 g

Therefore, with 6 lb = 2724 g and 1 pt = 0.473184 L, the density, d, of the material in grams per liter that has a density of 6 pounds per pint is given as follows;  

d = 2724 g/(0.473184 L)= 5756.75 g/L

The expression of density of the material with a density of 6 pound per pint in grams per liter (g/L) = 5756.75 g/L = 5756.75 g/L.

Answer:

height of the waste is 20.0 inches.

Step-by-step explanation:

given data

volume = 5, 667.7cubic inches

radius = 9.5 inches

solution

we use here volume of a cylinder is express as

V = πr²h     .................1

put here value

5667.7 = (3.14) × (9.5²) × h

solve it we get

h = 20 inch

so height of the waste is 20.0 inches.

Step-by-step explanation:

If we are solving for t, we have to remember that we have to isolate the variable (get its on its own). Since -1 is with t on the same side of the equation right now, we have to move the -1 to the other side of the equation. To do so, we add it's opposite to the right side (+1). Then, the -1 cancels out so we are left with an isolated t.

-6 = t - 1 (+1)

-6 = t

But we are not done yet! Whatever we do on one side, we have to do on the other side. Since we added 1 to the right, we have to add 1 on the left, too. So we add 1 to -6.

(+1) -6 = t

-6 + 1 = -5

-5 = t

Our final answer: t = - 5 (it can also be written as - 5 = t, but most people prefer the variable going first)

Answer:

1 1/2 ---------> 3/4

x --------------> 9

We clear the value of x:

x = ((9) / (3/4)) * (1 1/2)

Rewriting we have:

x = ((9) * (4/3)) * (1 1/2)

x = (36/3) * (1 1/2)

x = (12) * (1 1/2)

x = (12) * (3/2)

Answer:

DF=41

Step-by-step explanation:

It is given that F is the midpoint of DE. We know that, midpoint bisects the line segment. So,

DF=FE

3x+5=5x-19

Subtracting both sides by 3x

3x+5-3x=5x-19-3x

5=2x-19

Subtract both sides by 5

5-5=2x-19-5

0=2x-24

2x=24

x=12

So, the value of x is 12.

Put x = 12 in DF=3x+5

DF=3(12)+5

DF= 36+5

DF = 41

So, the value of DF is 41.
