What is the square root of 83 to the nearest tenth?

This question is based on the concept of solving a two linear equation.

Thus, the cost of one bath towel is $9 and one hand towel is $4.

Given:

Number of  ordered of hand towels is 27 and bath towels is 48 and for a bill of $540 for the first hotel.

Number of  ordered of hand towels is 50 and bath towels is 24 and for a bill of $416 for the other hotel.

We need tom determined the cost of one hand towel and one bath towel.

According to the question:

Let the  hand towels be h  and bath towels be b.

Therefore, equation of first hotel is

27h + 48b = 540........(1)

Equation of second hotel is

50h + 24b = 416.........(2)

Now, solving both equation for h and b.

Equation (2) multiplying by -2.

-100 h -48 b = - 832..................(3)

Now, solve equation (1) and (3)

27h + 48b = 540  and -100h - 48b = - 832

⇒ -73 h = - 292

⇒ h = -292 / -73

⇒ h = 4

Therefore, the cost of 1 hand towel is $4.

Now, putting the value of h = 4 in equation (1).

⇒ 27(4) + 48b = 540

⇒ 108 + 48b = 540

⇒ 48b = 540 - 108

⇒ 48b = 432

⇒ b = 432/48

⇒ b = 9

Therefore, the cost of 1 bath towel is $9.

Thus, the cost of one bath towel is $9 and one hand towel is $4.

Answer:

75°

Step-by-step explanation:

The angle is our unknown, so we will call it x.  If x is the angle, then its complement is 90 - x (complementary angles add up to 90).  The word "is" means "equals", and "5 times" is multiplying the complementary by 5:

x = 5(90 - x) so

x = 450 - 5x

Combine like terms to get

6x = 450 so

x = 75

The other angle, the complement to that angle, is 90 - 75 = 15

The larger angle is 75°

The altitude of the plane in miles will be 4.5144 miles.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a plane is flying at an altitude of 23,760 feet. The height of the plane in miles will be calculated as,

Height = 23760 feet

1 feet = 0.00019 miles

Height = 23760 x 0.00019 miles

Height = 4.5144

[tex](y-(0))=\dfrac{4-0}{-6-2}(x-2)\\\\\Rightarrow\y=\dfrac{4}{-8}(x-2)\\\\\Rightarrow\ y=\dfrac{-1}{2}(x-2)[/tex]

Answer: Jeniffer wins $25 per blanket. and she must pay $150 to renth the booth.

a) So the equation of Jennifer's profit is P(x) = $25*x - $150.

where x is the number of blankets that she sells, 25*x is positive because that is the money she wins, and the 150 is negative because is the money that she has to pay for the rent.

b) For breaking even, the profit must be equal to zero, it means that she doesn't lose or win anything. Then we do P(x) = 0 = $25*x - $150.

then 25*x = 150

       x = 150/25 = 6

So she must sell 6 blankets to break even.

Answer:

  use logarithms

Step-by-step explanation:

Taking the logarithm of an expression with a variable in the exponent makes the exponent become a coefficient of the logarithm of the base.

You will note that this approach works well enough for ...

  a^(x+3) = b^(x-6) . . . . . . . . . . . variables in the exponents

  (x+3)log(a) = (x-6)log(b) . . . . . a linear equation after taking logs

but doesn't do anything to help you solve ...

  x +3 = b^(x -6)

There is no algebraic way to solve equations that are a mix of polynomial and exponential functions.

Some functions have been defined to help in certain situations. For example, the "product log" function (or its inverse) can be used to solve a certain class of equations with variables in the exponent. However, these functions and their use are not normally studied in algebra courses.

In any event, I find a graphing calculator to be an extremely useful tool for solving exponential equations.

To solve an expression with variables in the exponents, you apply the rules of exponents.

When solving an expression with variables in the exponents, you need to apply the rules of exponents. Here are the key rules:

Answer:

f(x) intersect the x-axis ate ( 4 , 0 ) and ( -1/3 , 0)

Step-by-step explanation:

Given function, [tex]f(x)=3x^2-11x-4[/tex]

We need to find this function cuts x-axis at what point.

let, [tex]y=3x^2-11x-4[/tex]

We know that points on x-axis has y-coordinate equal to 0.

So, we put y = 0 to find value of x.

By putting y = 0, we get

[tex]0=3x^2-11x-4[/tex]

[tex]3x^2-11x-4=0[/tex]

solving by quadratic formula,

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-(-11)\pm\sqrt{(-11)^2-4\times3\times(-4)}}{2\times3}[/tex]

[tex]x=\frac{11\pm\sqrt{121+48}}{6}[/tex]

[tex]x=\frac{11\pm\sqrt{169}}{6}[/tex]

[tex]x=\frac{11\pm13}{6}[/tex]

[tex]x=\frac{11+13}{6}\:\:and\:\:x=\frac{11-13}{6}[/tex]

[tex]x=\frac{24}{6}\:\:and\:\:x=\frac{-2}{6}[/tex]

[tex]x=4\:\:and\:\:x=\frac{-1}{3}[/tex]

Therefore, f(x) intersect the x-axis ate ( 4 , 0 ) and ( -1/3 , 0)

Final answer:

The operation b \\u222a (a \\u2229 c) combines the unique elements of set b with the intersection of sets a and c, resulting in the set {-4, -2, 0, 1, 2, 3, 4}.

Explanation:

The student is asked to perform the operation b \\u222a (a \\u2229 c), given three sets a, b, and c. To do this, we need to first find the intersection of sets a and c, which is the set of elements that are both in a and in c. Then we find the union of set b with this intersection, which includes all the elements that are either in b or in the intersection of a and c.

Set a: {-3, -2, -1, 0, 1, 2, 3}

Set b: {-4, -2, 0, 2, 4}

Set c: {0, 1, 2, 3, 4}

First, find the intersection: a \\u2229 c = {0, 1, 2, 3}.

Next, find the union with set b: b \\u222a (a \\u2229 c) = {-4, -2, 0, 1, 2, 3, 4}.

The final result is the set {-4, -2, 0, 1, 2, 3, 4}, which contains all unique elements from both sets b and the intersection of a and c.

Answer:

The price of 1 gallon of gasoline is $2.90.

Step-by-step explanation:

You buy 8 gallons of gasoline at p dollars per gallon and pay $23.20.

We get the expression:

[tex]8p=23.20[/tex]

We can find one gallon as: p=[tex]\frac{23.20}{8}[/tex]

=> p = $2.90

Hence, the price of 1 gallon of gasoline is $2.90.

Disadvantages of the Piece-Rate Pay System:

Hindered Production -- It's virtually impossible to predict how much product can be created within a set time under this system, because the system doesn’t easily lend itself to regulating and encouraging a production line.

Sick or Injured Workers -- Working for piece-rate pay means that workers might come to work when they are ill, thereby risking the health of their coworkers. This could shut down or seriously reduce production output. Additionally, depending on the materials and equipment, if workers are working too quickly in an attempt to produce more, workers could potentially injure themselves, which could open up the company to liability.

Reduced Quality -- When the focus is on quantity, the output the quality may suffer. Such a system requires dedicated employees who are determined to learn their craft thoroughly and then to increase the output. Employees are human, however, and it can be difficult to work at a rapid pace over a long duration. This can mean that employees may continue to work at a rapid pace but that production may produce items of reduced quality.

The amount of 15% alcohol Bruce should use ls 20 mL

Using the equation given in the question :

0.10x + 0.15(50 - x) = 0.12(50)

0.10x + 7.5 - 0.15x = 6

Collect like terms

-0.05 = 6 - 7.5

-0.05x = - 1.5

x = 1.5 / 0.05

x = 30 mL

The amount of 15% solution to be used is related can be calculated thus :

Amount of 15% solution = 50 - x

Amount of 15% solution = 50 - 30 = 20mL

Therefore, 20mL of 15% solution is required.
