Answer:

28 meters²

Step-by-step explanation:

We can break the shape into two rectangles. One of the rectangles has length 5 and height 2. The other rectangle has a height of 6 and a width of three. You can refer to the attached image.

To find the total area, we simply have to sum the areas of the two rectangles.

[tex]A = 5*2 + 6*3\\A = 10 + 18\\A = 28[/tex]

The total are of the shape is 28 meters²

Answer:

28 m²

Step-by-step explanation:

The figure is composed of 2 rectangles

The right rectangle has sides 3m and 6 m

The left rectangle has sides 5 m and (6 - 4) = 2 m

The area (A) of the figure is the sum of the 2 rectangles which form it

A = (3 × 6 ) + (5 × 2 )

   = 18 + 10

   = 28 m²

The correct option is the first one. An animal skull

Step-by-step explanation:

The correct option is the first one. An animal skull

The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon.

The age detection of the ancient objects are very tough,due to no records are available about the objects.

That's why scientists use carbon-14 dating process.

In this picture, the only object that contains organic material is the animal skull, thus it is the only one that can be dated with this method.

Answer:

The correct option is animal skull

Step-by-step explanation:

Carbon-14 dating is a method for determining the age of an object containing organic material by utilising the properties of a radioactive isotope of carbon. As we have no records of the object, it's become very difficult to detect the age of an object . In such a situation, carbon-14 dating process helps .

In the given picture, animal skull is the only object that contains organic material , so it is the only object for which  geologist would use carbon-14 dating to determine age.

Therefore, the correct option is animal scull ( first one )

Answer:

Step-by-step explanation:

So 10.55$ for an hour at the ice-cream store, and he works 8 hours.

So 8 * 10.55$ because he earns 10.55$ eight times, since he works 8 hours;

then, you would get $84.40 for a week at the ice-cream store.

Now he earns 13.85$ per hour at the movie theater, for a total of 7 hours.

Again, 13.85$ * 7 since he earns 13.85$ 7 times (7 hours); he gets $96.95 for a week at the movie theater.

1. so we want to know how much does mike earn a week, which basically means how much money did he earn in total during the week working at two jobs?

so you just add what you calculated, you get $181.35 in total.

2. So we want to know how much he has left after 22 percent of the total amount of money that he earned is taken away, due to taxes.

So we want to know how much is 22 percent of the total, so $181.35 * 22% = $39.89

So now we know that $39.89 is 22 percent of the total amount ($181.35), and we know that it is taken away from us, so we subtract $39.89 from $181.35, and you would get $141.46.

So, $141.46 is the amount of money left for Mike after paying his taxes.

3. So we want to know which jobs pays him more before paying the taxes. According to the first question, he earns $84.40 a week at the ice cream store, and $96.95 a week at the movie theater. So, obviously the movie theater pays him more.

It has two questions in one, and the second question asks how much more does the higher paying job pays than the lower paying one. So they're asking what is the difference between the two prices?

So we need to subtract $96.95 (the higher paying one) - $84.40 (the lower paying one), and you would get $12.55.

So, the movie theater pays Mike $12.55 more dollars than the ice cream store.

Step-by-step explanation:

139.95 x 19 = 2,659.05 In total the 19 clarinets = $ 2,659.05

$ 4,578.45 - $ 2,659.05 = $ 1919.40 In toal the 12 trumpets are = $ 1,919.40

$ 1,919.40 ÷ 12 = $ 159.95 The trumpets cost $ 159.95 each.

Hope this helps you out : )

If the music store sold 12 trumoets and 19 clarinets last month and clariners sell for $139.95 and the store made $4,578.45. The price of a trumpet is $159.95.

Let's denote the price of a trumpet as "t" dollars.

The revenue from trumpet sales would be 12 times the price of a trumpet (12t) and the revenue from clarinet sales would be 19 times the price of a clarinet ($139.95):

Revenue from trumpets + Revenue from clarinets = Total revenue

12t + 19 * $139.95 = $4578.45

Now solve for the price of a trumpet (t):

12t + 19 * $139.95 = $4578.45

12t + $2659.05 = $4578.45

12t = $4578.45 - $2659.05

12t = $1919.4

t = $1919.4 / 12

t ≈ $159.95

Therefore the price of a trumpet is $159.95.

Answer:

Part 1) Is a cubic expression

Part 2) The quadratic expression is 12x² + 8x − 1

Step-by-step explanation:

Part 1) Classify the expression: 5x³ + 2x − 3

we know that

Polynomials can be classified two different ways - by the number of terms and by their degree.

so

a) By the number of terms is a trinomial, because has three terms

b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable

The highest exponent is 3 so this is a 3rd degree trinomial  

therefore

Is a cubic expression

Part 2) Choose the expression that represents a quadratic expression

we know that

If the expression is a quadratic equation , then the highest exponent of the variable is 2

therefore

The quadratic expression is 12x² + 8x − 1

Answer:

1. Cubic expression

2. [tex]12x^2+8x-1[/tex]

Step-by-step explanation:

1. We have the expression [tex]5x^3+2x-3[/tex] and we have to classify it.

A quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].

We can see that the first term is squared. And in the expression that we have to classify the first term is raised to the cubic, then it isn't a quadratic expression.

A linear expression has the form [tex]ax+b[/tex].

We can see that it only has two terms and the first term has exponent 1. The expression [tex]5x^3+2x-3[/tex] has 3 terms and the first term has exponent 2 then it isn't a linear expression.

A cubic expression has the form[tex]ax^3+bx^2+cx+d[/tex].

We can see that the first term is raised to the cubic. And [tex]5x^3+2x-3[/tex] is raised to the cubic.

We can rewrite it: [tex]5x^3+2x-3=5x^3+0x^2+2x-3[/tex]

[tex]a=5\\b=0\\c=2\\d=-3[/tex]

The expression [tex]5x^3+2x-3[/tex] agrees with the definition of a cubic expression. Then it's a cubic expression.

An Exponential expression has the form [tex]y=ab^x, a>0[/tex]

2. We said that a quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].

Then the expression that agrees with the definition is [tex]12x^2+8x-1,a\neq 0[/tex]

Answer:

n=-2n-12

Step-by-step explanation:

Distribute the -3 to 2n-4, which equals -6n+12. Putting your whole equation back together, you will have -8-n=-6n+12. If you add 8n over to the other side, your equation becomes -n=2n+12. Now all you have to do here is divide the negative from -1 thats in front of n from 2n+12, making your answer n=-2n-12.

To solve the linear equation -8 - n = -3(2n - 4), we distribute, combine like terms, and isolate the variable to find that n = 4.

The equation presented, -8 - n = -3(2n - 4), is a linear equation where the goal is to solve for the variable n. We start by simplifying and rearranging the equation to isolate n on one side. To solve the equation:

Distribute the -3 through the parentheses on the right side: -8 - n = -6n + 12.

Move all terms involving n to one side by adding 6n to both sides: -8 + 6n - n = 12.

Combine like terms: -8 + 5n = 12.

Next, add 8 to both sides to isolate the term with n: 5n = 20.

Finally, divide both sides by 5 to solve for n: n = 4.

Hope it helps.

Answer:

1/66

Step-by-step explanation:

0.0151515 can be converted to the fraction 5/333.

Repeating decimals can be converted to fractions by setting the repeating part as x and subtracting the non-repeating part.

For example, to convert 0.0151515 to a fraction, let x = 0.015 and y = 0.1515, then subtract them: x = 0.015, 1000x = 15, y = 0.1515, 10000y = 1515. Subtract both: 999y = 1500 - 15 = 1485.

Therefore, the fraction is 0.0151515 = 15/999 = 5/333.

The angles are 18° and 72° respectively.

Since, we are told that they are complementary angles, that means that their sum will be equal to 90°

Therefore E + F = 90°

Based on the question, E = F + 54°. Therefore, E + F = 90°.

F + 54° + F = 90°

Collect like terms

2F = 90 - 54°

2F = 36°

F = 36°/2 = 18°

The value of F is 18°

Therefore, E = F + 54° = 18° + 54° ,= 72°

The angles are 18° and 72°.

The measure of angle E is 72 degrees and the measure of angle F is 18 degrees.

Let's represent the measure of angle E as x and the measure of angle F as y. Since the angles are complementary, we know that x + y = 90. We also know that x = y + 54. By substituting the value of x into the first equation, we get (y + 54) + y = 90, which simplifies to 2y + 54 = 90. Solving for y, we find that y = 18. Substituting this value back into the equation for x, we get x = 18 + 54 = 72. Therefore, the measure of angle E is 72 degrees and the measure of angle F is 18 degrees.
