Answer:

11/14

Step-by-step explanation:

Their sum is 180 degrees. You set up an equation and get:

10x + 30 + 18x + 128 = 180

Combine Like Terms

28x + 158 = 180

28x = 22

x = 11/14

On solving the question 30.27 + 1.9 + 22.952 we get 55.1

Significant figures are important in calculations to maintain accuracy.

To add the numbers 30.27, 1.9, and 22.952:

Add the numbers: 30.27 + 1.9 + 22.952 = 55.122.

The number of significant figures in each of the given numbers is different. The answer should have the same number of decimal places as the number with the fewest decimal places, which in this case is 1.9. Thus, the answer should be rounded to 55.1

Answer:

Step-by-step explanation:

To use the formula for the volume of a prism to remember the formula for the volume of a cylinder, you can think of a cylinder as a prism with circular bases. The formula for the volume of a prism is given by multiplying the base area by the height. In the case of a cylinder, the base area is the area of a circle, which is πr² (where r is the radius), and the height is the height of the cylinder. Therefore, the formula for the volume of a cylinder becomes V = πr²h.

The formula for the volume of a cone is related to the formula for the volume of a cylinder because a cone can be thought of as a pyramid with a circular base. The formula for the volume of a cone is given by multiplying the base area (which is a circle) by the height and dividing by 3. Since the base area of a cone is πr² (where r is the radius), and the height of the cone is h, the formula for the volume of a cone becomes V = (1/3)πr²h. The volume of a cone is exactly one-third of the volume of a cylinder with the same base area and height.

It's important to note that the formulas for the volume of a cylinder, cone, and sphere are derived based on their geometric shapes and properties. Understanding these relationships and connections can help in remembering and applying the formulas correctly in problem-solving situations.

To remember the formula for the volume of a cylinder, think of it as a prism with circular bases. The formula is the area of the base times the height. The volume of a cone with the same radius and height is one-third of the volume of the cylinder.

To use the formula for the volume of a prism to remember the formula for the volume of a cylinder, you can think of a cylinder as a prism with circular bases. The formula for the volume of a prism is the area of the base times the height. Since the bases of a cylinder are circles, the formula becomes the area of the base (πr²) times the height (h). The formula for the volume of a cylinder is related to the formula for the volume of a cone because if you take a cone with the same radius and height as a cylinder, the volume of the cone will be one-third of the volume of the cylinder (Vcone = 1/3 * Vcylinder).

Step-by-step explanation:

It said on the "show me" box at the bottom of the screen :)

The required angle of the projectile motion having range 20 m and initial velocity 15 m is 30.29°

Range of the projectile motion:

The formula for finding projectile motion is given by

Range R = [tex]\frac{v^2sin2\theta}{g}[/tex]

where v is the initial velocity and g is acceleration and [tex]\theta[/tex] is the projectile angle of the object

If we have given range and initial velocity with acceleration then by substituting above range formula we can find angle of the projectile

Here we have given that

R = 20 m

v = 15 m/s

g = 9.8 m/s^2

Therefore

[tex]20=\frac{15^2sin2\theta}{9.8}[/tex]

[tex]sin2\theta=\frac{20(9.8)}{225}[/tex]

[tex]\theta[/tex] = 30.29

This is the required angle of the projectile

Answer:

The answer is A

Step-by-step explanation:

Some of the population may not have access to other types of phones.

The policy of conducting a portion of surveys on mobile phones helps address the source of bias wherein some people may not have access to other types of phones. By including mobile phones, pollsters can have a more representative sample, reflecting the population more accurately. However, this does not guarantee participation or comprehension of survey questions.

The policy of political pollsters to conduct a percentage of their telephone interviews by calling mobile phones best addresses the source of bias that some of the population may not have access to other types of phones. This is reflective of a shift in communication behaviors wherein a significant percentage of the population exclusively uses mobile phones, especially among younger and middle-aged adults. This phenomenon could lead to a selection bias if only landline numbers were used, as the respondents would likely skew toward older individuals and those who are at home more often.

By integrating mobile phones in their survey methods, the pollsters are able to get a more representative sample that more accurately reflects the entire population. For instance, random-digit-dialing is a technique that allows pollsters to include respondents who have unlisted or mobile numbers. Similarly, geographically-based screenings can be employed to avoid regional bias.

However, it is important to note that including mobile phones in the survey does not address other kinds of bias. For instance, reaching out to potential respondents does not guarantee their participation, and it does not mean that the respondents would fully understand the wording of the survey questions. It only helps in achieving a more demographically reflective sample.

we can write the equation of the line in slope-intercept form:

[tex]y =[/tex][tex](-1/12)x + 6[/tex]

To find the equation of a line in slope-intercept form ([tex]y = mx + b[/tex]), we need to determine the slope (m) and the y-intercept (b).

Given two points (0, 6) and (12, 5), we can calculate the slope (m) using the formula:

[tex]m = (y2 - y1) / (x2 - x1)[/tex]

Using the coordinates (0, 6) and (12, 5):

[tex]m = (5 - 6) / (12 - 0)[/tex]

[tex]= -1 / 12[/tex]

Now that we have the slope (m), we can substitute it into the slope-intercept form equation:

[tex]y = mx + b[/tex]

Using the coordinates (0, 6):

[tex]6 = (-1/12)(0) + b[/tex]

6 = b

Therefore, the y-intercept (b) is 6.

A slope-intercept equation is a linear equation written in the form y = mx + b, where m represents the slope of the line and b represents the y-intercept. The slope (m) determines the steepness or direction of the line, while the y-intercept (b) is the point where the line intersects the y-axis. By using this equation, we can easily identify the relationship between the x and y coordinateson  the line, making it convenient for graphing, understanding the line's behavior, and predicting the value of y for a given x.

Answer: y=4

Step-by-step explanation:

8y+1=6y+9 -Because y is equal the equations are as well.

2y+1=9- Take 6y to the other side by -6y

2y=8-Take one over by -1

y=4-Divide 8 by 2 to get y=4

Answer:

The value of y is 4

Step-by-step explanation:

If the some of the counters in each box are the same, then A = B

If A is 8y + 1 and B is 6y + 9

Since A = B, we can say

8y + 1 = 6y + 9

Collecting like terms, we will have

8y - 6y = 9 - 1

2y = 8

Dividing both sides by 2, we will have

y = 8/2

Answer:

54°

Step-by-step explanation:

Complementary angles sum to 90°, thus

∠ Z2 = 90° - 36° = 54°

Answer:

∠a=80

∠b=50

Step-by-step explanation:

∠a and 100 are on a straight line. Therefore they are supplementary, and add to 180 degrees. So, we can say that:

∠a+100=180

To solve, subtract 100 from both sides. This will leave ∠a by itself.

∠a +100-100=180-100

∠a=80

The angles in a triangle must add to 180 degrees. Therefore,

∠a + ∠b + 50= 180

We know ∠a is 80, so we can substitute that in

80+ ∠b +50 =180

∠b+80+50=180

Combine like terms

∠b+(80+50)=180

∠b+130=180

To solve, subtract 130 from both sides. This will leave ∠b by itself.

∠b+130-130=180-130

∠b=50

Answer:

∠a = 80° and ∠b = 50°

Step-by-step explanation:

Look at angle a. Angle a and 100 both lie on the same line, which means they are supplementary and add up to 180. Then we can write: m∠a + 100 = 180. To solve this for a, we simply subtract 100 from both sides:

m∠a = 80°

Now, look at the triangle. All the angles in a triangle add up to 180, so we have the equation: m∠b + 80 + 50 = 180. Solve for b by subtracting 80 and 50 from both sides: m∠b = 50°.

Thus, ∠a = 80° and ∠b = 50°.
