A mosquito starts his flight in the air at 10 feet below sea level in a canyon. He then ascends to 18 feet above sea level. What was the change in the height if his flight

Answer:

#17 Complementary

#18 Neither

Step-by-step explanation:

Complementary Angle: If sum of two angles is right angle then both angles are complementary to each other.

Supplementary Angle: If sum of two angles is straight angle then both angles are supplementary to each other.

#17 In figure 1

∠1 + ∠2 = 90°

Sum of ∠1 and ∠2 is 90° which is right angle.

Therefore, ∠1 and ∠2  are complementary angles.

#18 In figure 1

Sum of ∠1 and ∠2 neither 90° not 180°

Therefore, ∠1 and ∠2  neither complementary angles nor supplementary angles.

Answer:

Yes

Step-by-step explanation:

∠4 = ∠7 ( vertical angles )

The angles are opposite angles of the vertex with the same straight lines

Angle 4 and 7 are vertically opposite angle.

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal.

in the given systems of line,

Angle 1, 2, 3, 4, 5, 6, 7, and angle 8 are given.

To determine angle 4 and angle 7 are vertically opposite or not.

Use vertically opposite angle property,

Since, angle 4 and 7 are at same vertex and apposite to each other,

Therefore, angle 4 and 7 are vertically opposite angles.

Solution:

1/2 are younger than 10.

1/20 are 10 years old.

1/10 are older than 10 but younger than 12.

70 are 12 years old.

Find Common Denominators.

1/2 = 10/20

1/20 = 1/20

1/10 = 2/10

Add.

10/20 + 1/20 + 2/10 = 13/20

Subtract.

20/20 - 13/20 = 7/20

So we now see that 7/20 = 70

Now we can see that 1/20 = 10

Answer:

10

Step-by-step explanation:

0.50 = x<10

0.05 = 10

0.10 = 10<x<12

70 students = 12+

How many are 10 yrs old?

0.50 + 0.05 + 0.10 = 0.65

To find the percent, multiply it by 100

0.65 * 100 = 65%

70 are 35%

70/0.35 = 200 total

200 * 0.05 = 10 ten-year-old students

Step-by-step explanation:

We are give two linear equations and asked to solve them. The two equations are

-3y+5x=26

-2y-5x=-16

Adding both equations

-5y=10

Dividing both sides by -5

The correct graph is b)

Step-by-step explanation:

To solve this problem you have to think about the graph of |x|, and traslate 2 units up, in "y" axis beacuse +2 is outside the |x|. If +2 were inside |x| (|x+2|), you have tyo traslate 2 units to the left.

The graph that represents the equation y =|x|+2 is option B.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given equation is y=|x|+2

y equal to mod x plus two.

y=|x|+2

Let us find the graph by finding few x and  y values of the equation.

x       0         1          2        3

y        2        3         4         5

The given points are exactly pointed in the second graph.

Hence, the graph that represents the equation y =|x|+2 is option B.

Answer:

the bread will cost around 28 dollars.

Step-by-step explanation:

To estimate the future cost of a $1.42 loaf of bread in 25 years based on inflation, we can use the compound interest formula with an assumed average inflation rate.

To calculate how much a $1.42 loaf of bread will cost in 25 years based on inflation, we need to consider the rate of inflation over that period. However, without that specific data, we can estimate the future cost of the bread using past inflation rates.

Let's assume an average inflation rate of 2% per year. To calculate the future cost, we can use the formula for compound interest: Future Price = Present Price * (1 + Inflation Rate)^Number of Years

For the loaf of bread, the future price will be: $1.42 * (1 + 0.02)^25 = $2.63

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:

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]

With,

[tex]a=12\\b=8\\c=1[/tex]

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.

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
