Is 5.424 greater than 5.343

None of the students is correct because the diameter of this circle is 7.5 inches.

Mathematically, the circumference of a circle can be calculated by using this mathematical expression:

C = 2πr or C = πD

Where:

Substituting the given parameters into the circumference of a circle formula, we have the following diameter;

23.55 = 3.14 × D

D = 23.55/3.14

EXPLANATION

Answer:

5 men should be subtracted.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.

How many men should be working to complete the work in 32 days?

20 men - 24 days

x men - 32 days

Then

\(32x = 20*24\)

\(x = \frac{20*24}{32}\)

\(x = 15\)

How many men should be subtracted?

There are 20 to complete in 24 days.

15 are needed to complete in 32 days.

20 - 15 = 5

5 men should be subtracted.

Answer: 1.5

The equation X^2/2 - 8 = 2X - 2 has two solutions, X = 6 and X = -2. These are the values of X that satisfy the equation and make both equations Y = X^2/2 - 8 and Y = 2X - 2 intersect on the graph.

To find the solutions to the equation X^2/2 - 8 = 2X - 2, we need to set the two equations equal to each other and solve for X.

The equation is:

X^2/2 - 8 = 2X - 2

To simplify the equation, let's multiply both sides by 2 to eliminate the fraction:

X^2 - 16 = 4X - 4

Next, we rearrange the equation to have all terms on one side:

X^2 - 4X - 12 = 0

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's use factoring in this case:

(X - 6)(X + 2) = 0

Setting each factor equal to zero gives us two possible solutions:

X - 6 = 0 --> X = 6

X + 2 = 0 --> X = -2

So the solutions to the equation X^2/2 - 8 = 2X - 2 are X = 6 and X = -2.

Answer:

y = -2/3 x - 13/3

Step-by-step explanation:

y = -2/3 x + 3/2

y = mx + b

m = -2/3

The slope of the given line is -2/3. Parallel lines have equal slopes, so our line also has slope -2/3.

m = -2/3

y = mx + b

y = -2/3 x + b

Substitute the given point for x and y and solve for b.

-7 = -2/3 (4) + b

-21/3 = -8/3 + b

b = -13/3

Answer: y = -2/3 x - 13/3

Answer:

Diane is faster since her speed is higher.

Step-by-step explanation:

We can find each speed in yards per second.

Tom:

25 yards / 4 seconds = 6.25 yards/second

Diane:

20 yards / 3 seconds = 6.67 yards/second

Diane's speed is higher, 6.67 yd/s vs 6.25 yd/s, so Diane is faster.

Answer: Diane is faster since her speed is higher.

From the question, we have the following parameters that can be used in our computation:

The dilation of ABC by a scale factor of 2

This means that

Scale factor = 2

The general rule of dilation is that

using the above as a guide, we have the following:

AC = 2 * 5 = 10

C = 53 degrees

BC = 2 * 3 = 6

A = 37 degrees

430 teenagers

Step-by-step explanation:

Given the following question:

10% of 4300

In order to find the answer to this question, we will use the formula to calculate percentages.

\(\frac{p\times n}{100}\)
\(\frac{10\times4300}{100} =10\times4300=43000\div100=430\)
\(=430\)

10% of 4300 is "430" so they're 430 teenagers who attended the football game.

What are coordinates?

Coordinates are a set of numbers or values that represent the position of a point or object in a coordinate system. A coordinate system typically consists of two or more axes, such as the x-axis and y-axis in a Cartesian coordinate system, that intersect at a point called the origin. Coordinates are often written as ordered pairs (x, y) or as triplets (x, y, z) in three-dimensional space.

According to the question:
A cartesian plane has four quadrant. Each quadrant is represents as I,II,III,IV with different signs.
For example: quadrant one, quadrant two, quadrant three, and quadrant four. X-axis is a horizontal axis. Y-axis is a vertical axis X-coordinate is a horizontal position. Y-coordinate is a vertical position. Origin is a point of intersection of the two axes.

So the point E located in 3rd quadrant which is (-,-) it implies (-2,-3)

point E has value of -2,-3 at the x and y axis respectively.
Therefore, correct answer is (-2,-3).

Answer: x = √-6 - 4

(x+4)^2 + 6 = 0

(x+4)^2 = -6

√(x+4)^2 = √-6

x = √-6 - 4

Answer:

y = -8/3x + 8

Step-by-step explanation:

Step 1:  Identify which values we have and need to find in the slope-intercept form:

The general equation of the slope-intercept form of a line is given by:

y = mx + b, where

Since we're told that the y-intercept is 8, this is our b value in the slope-intercept form.

Step 2:  Find m, the slope of the line:

Thus, we can find m, the slope of the line by plugging in (3, 0) for (x, y) and 8 for b:

0 = m(3) + 8

0 = 3m + 8

-8 = 3m

-8/3 = m

Thus, the slope is -8/3.

Therefore, the the equation of the line in slope-intercept form whose x-intercept is 3 and whose y-intercept is 8 is y = -8/3x + 8.

Optional Step 3:  Check the validity of the answer:

Thus, we can check that we've found the correct equation in slope-intercept form by plugging in (3, 0) and (0, 8) for (x, y), -8/3 for m, and 8 for b and seeing if we get the same answer on both sides of the equation when simplifying:

Plugging in (3, 0) for (x, y) along with -8/3 for m and 8 for b:

0 = -8/3(3) + 8

0 = -24/3 + 8

0 = -8 = 8

0 = 0

Plugging in (0, 8) for (x, y) along with -8/3 for m and 8 for b;

8 = -8/3(0) + 8

8 = 0 + 8

8 = 8

Thus, the equation we've found is correct as it contains the points (3, 0) and (0, 8), which are the x and y intercepts.
