The measure of angle 9 is 45 degrees.

What is complementary angles?

Complementary angles are those whose combined angle is exactly 90 degrees. 30 degrees and 60 degrees, for instance, are complementary angles.

Given:

Angle 9 and angle 10 are corresponding angles formed by two parallel lines cut by transversal.

The angles are also complimentary.

We have to find the measure of angle 9.

If <9 and <10 are corresponding, it means they are equal i.e <9 = <10

Since <9 and <10 are also complementary angles, their sum will be 90 degrees

<9+<10 = 90

<9 + <9 = 90

2m<9 = 90

m<2 = 90/2

m<2 = 45 degrees

Hence the measure of angle 9 is 45 degrees.

The combined length for three shortest jumps is 43 feet. We can find out by analyzing the graph and its entities.

What are graph and entities ?

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

Entity is any data or any existing object .

From the graph:

14*1/4 feet = by 2 students

14*1/2 feet = by 3 students

14*3/4 feet = by 1 student

15 feet = by 1 student

So the three shortest jumps are 14*1/4 , 14*1/4 , 14*1/2.

Total distance = 57/4 + 57/4 + 58/4

                        = 43 feet.

If Inez has 8/3 cup of raisings and each batch takes 2/3 cup of raisins, she may create 4 batches of raisin granola bars.

In mathematics, a fraction is used to represent a piece or part of a whole. It symbolizes the equal pieces of the whole. A fraction is made up of two parts: the numerator and the denominator. The top number is known as the numerator, while the bottom number is known as the denominator. A common fraction is a numeric representation of a rational integer. The same number can be expressed as a decimal, a percentage, or with a negative exponent. Fractions indicate pieces of a whole or group of items. A fraction is made up of two components. The number at the top of the line is referred to as the numerator. It specifies the number of equal sections of the whole or collection that are taken. The figure below the line is denominator.

Here,

8/3÷2/3=4

2/3 • 4 = 8/3

2/3 + 2/3 + 2/3 + 2/3 = 8/3

2/3 = 0.67

0.67 • 4 = 2.67

8/3 = 2.67

The length of the side AB represented by x in the triangle ABC is equal to 16 using the trigonometric ratio of sine.

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

The triangles ABC and ADB are right-angled triangles, we shall be considering the trigonometric ratio of the sine of angle A which is common to both triangles.

For triangle ABC;

sinA = adjacent/hypotenuse

sinA = x/32

for triangle ADB;

sinA = 8/x

thus we can say that;

x/32 = 8/x {cross multiplication}

x² = 3 × 32

x² = 256

x =√256 {take square root for both sides}

x = 16.

Therefore, 16 is the length of the side AB labelled x, using the trigonometric ratio of sine of the common angle A to the triangles ABC and ADB.

The scatterplots shown can be matched to the corresponding correlation coefficients , which are as follows :
Scatterplot A : -0.56

Scatterplot B : -0.96

Scatterplot C : 0.92

Scatterplot D : 0.53

What is correlation coefficient?
Correlation coefficient is a numerical measure of the degree of relationship between two variables. It is used to measure how closely related two variables are, and whether one variable is a good predictor of the other. It is measured on a scale of -1 to 1, with -1 representing a strong negative correlation, 0 representing no correlation, and 1 representing a strong positive correlation. A correlation coefficient of 0 suggests that the two variables are completely unrelated, while a coefficient of 1 suggests that the two variables are strongly related. Correlation coefficients can help to identify patterns in data and can be used to predict future values.

Note the following facts :

Scatterplot that shows a trend that rises from left to your right shows a positive correlation between two variables.

Scatterplot that descends from left to left to right shows a negative correlation between two variables.

The farther away the data points are from each other the greater the value the value of correlation coefficient.

In the collection, there are 11 nickels and 23 dimes. If each nickel is replaced with a quarter, the value of the collection becomes $5.05. So, C is correct. By writing them in the system of equations, we get the required value.

The given units are nickels, dimes, and quarters. Their conversion into dollars is as follows:

1 nickel = $0.05

1 dime = $0.10

1 quarter = $0.25

Given a collection of nickels and dimes is worth $2.85.

And there are 34 coins in the collection.

So, consider the number of nickel coins = n and the number of dime coins = d.

Then, the equation for the given collection is

n + d = 34...(1)

0.05n + 0.10d = 2.85...(2)

On simplifying (2), we get

5n + 10d = 2.85 × 100

⇒ 5n + 10d = 285

From (1), n = 34 - d, we get

5(34 - d) + 10d = 285

⇒ 170 - 5d + 10d = 285

⇒ 5d = 285 - 170 = 115

∴ d = 115/5 = 23

Thus, the number of dime coins is 23.

So, from (1), we get n + 23 = 34 ⇒ n = 34 - 23 = 11

∴ n = 11

Thus, the number of nickel coins is 11.

If each nickel coin in the collection is replaced with a quarter, then the value of the collection is

q + d = 34 and 0.25q + 0.10d = Y

Here q = 11; d = 23

So, we get

0.25(11) + 0.10(23) = Y

⇒ 2.75 + 2.3 = Y

⇒ 5.05 = Y

∴ Y = $5.05

The value of the new collection becomes $5.05.

In mathematics, an integral assigns numerical values to functions to represent concepts like volume, area, and displacement that result from combining infinitesimally small amounts of data.

Integration is the action of locating integrals.

So, the number of automobiles that cross an intersection each hour is:

Answer:

630

Step-by-step explanation:

35% of 1800 = 0.35 × 1800 = 630

The required area under the curve of function v(t) is 195 square miles, which depicts the total distance traveled by car during the 3 hours.

The area under the curve of the function v(t) represents the total distance traveled by the car over the given time period.

The function v(t) is defined as the speed of the car (in miles per hour) at any given time t (in hours). Since the speed is constant at 65 miles per hour, the graph of v(t) will be a straight horizontal line at y = 65.

To find the distance traveled, we need to multiply the speed (in miles per hour) by the time (in hours):

Distance = Speed * Time

Following the given case, the speed is 65 miles per hour, and the car traveled for 3 hours:

Distance = 65 miles/hour * 3 hours = 195 miles

So, the area under the curve of v(t) is 195 square miles, which represents the total distance traveled by car during the 3 hours.

Step-by-step explanation:

The function simulates exponential decay, and it degrades by 5.1% for every increment in x.

Explosive increase and decay are common in situations where quantities change rapidly. It has been suggested that exponential development and decay follow a geometric progression. Quantities that change exponentially rather than continually are referred to be exponentially growing or decaying.

As per the given data in the question,

An exponential function with the formula y = a[tex]r^x[/tex] is the function that is given.

a = 330

r = 0.949

The function indicates exponential growth if the base r is larger than 1. The function shows exponential decline if indeed the base r is far less than 1. In this instance, the function depicts exponential decline because the base r is smaller than 1, or 0.949.

If we want to describe the rate of reduction as a percentage, we can remove the base r by 1 and multiply it by 100.

The rate of reduction as a percentage in this instance is:

1 - 0.949 = 0.051 ×100

Answer:

Perimeter of the square patch is 240 cm.

Step-by-step explanation:

If the perimeter of each rectangular piece is 48 cm, then the length of each side of each rectangular piece is 12 cm. When the rectangular pieces are arranged to form a square patch, the patch will have 5 rows and 5 columns of rectangular pieces. Since the rectangular pieces are identical, the length of each side of the square patch will be 5 times the length of one side of a rectangular piece. Therefore, the length of each side of the square patch will be 5 * 12 cm = 60 cm.

The perimeter of the square patch is the sum of the lengths of all four sides of the patch. Since all sides of the patch have the same length, the perimeter of the square patch will be 4 * 60 cm = 240
