Final answer:

Dayton has 3 bags of frozen vegetables, with each bag weighing 5/8 pound. He can make 1 pot of soup with 7/8 of another pot using these vegetables.

Explanation:

Dayton has 3 bags of frozen vegetables, and each bag contains 5/8 pound of vegetables. To find the total weight of the vegetables, we multiply the weight of one bag by the number of bags: (5/8) * 3 = 15/8 pounds. Since each pot of soup requires 1 pound of vegetables, we divide the total weight of the vegetables by 1 pound to find the number of pots of soup Dayton can make: (15/8) / 1 = 15/8 pots of soup. However, we can simplify this fraction to a mixed number: 15/8 = 1 and 7/8. So Dayton can make 1 pot of soup with 7/8 of another pot.

Step-by-step explanation:

2

Square roots are not polynomials

3

The highest degree of one term in the polynomial is 4

4

Terms are separated by (+) or (-) signs. If you count them up there are 4

Answer:

C, D, D, B

Step-by-step explanation:

2. A polynomial has only integer exponents, no square roots.  So C is not a polynomial.

3. The degree of the polynomial is the sum of the exponents of the highest term.  p has an exponent of 1 and q has an exponent 4, so 1+4 = 5. D

4. Count the number of terms being added or subtracted.  p^3, 4pq^2, q^2, and -3q.  So there are 4 terms. D

5. Standard form of a polynomial is written from the highest exponent to the lowest.  So the answer is B.

Answer:

Divide the standard deviation of the sample measures by 8

Step-by-step explanation:

Given

measurements in data set=500

measurements in sample=64

Standard error of sample=?

As per the formula of standard error

Standard error= standard deviation/ square root of the number of measurements

                        = σ/√n

Here as we need to find standard error of the sample hence n=64

therefore √64= 8

The above equation will become:

standard error of the sample= σ/8 i.e. Divide the standard deviation of the sample measures by 8!

Answer:

x ≈ 6.5

Step-by-step explanation:

We have the epresion [tex]tan(18)=\frac{x}{20}[/tex] and we want to find the value of [tex]x[/tex].

Let's do it step-by-step

Step 1. Multiply both sides of the equation by 20

[tex]tan(18)=\frac{x}{20}[/tex]

[tex]20tan(18)=(\frac{x}{20} )(20)[/tex]

[tex]20tan(18)=x[/tex]

Step 2. use the reflexive property of equality: if [tex]a=b[/tex] then [tex]b=a[/tex]

[tex]20tan(18)=x[/tex]

[tex]x=20tan(18)[/tex]

Step 3. Using a calculator we get that [tex]tan(18)=0.325[/tex].  Replacing that value we get

[tex]x=20(0.325)[/tex]

x ≈ 6.5

We can conclude that the value of x is approximately 6.5

Answer:

Rectangle

Step-by-step explanation:

In order for a paralleligram to be inscribed in a circle it has to have four 90º angles, this is why the only parallelogram that can be inscribed into a circle is the rectangle, this includes sqaures, since squares are basically rectangles with equal sides.

Answer:

x=9

Step-by-step explanation:

Answer:

The correct option is A. FLED is definitely a parallelogram .

Step-by-step explanation:

From the given figure it is clear that the angle F and angle E are same. Angle L and angle D are same.

[tex]\angle F=\angle E[/tex]

[tex]\angle L=\angle D[/tex]

According to the properties of parallelogram, a quadrilateral is called parallelogram if and only if there are two pairs of congruent opposite angles (but not equal to 90°, otherwise it will be a square or rectangle).

Since we have two pairs of congruent opposite angles which are not a right angle, therefore the statement "FLED is definitely a parallelogram" is true.

Hence, option A is correct.

The sequence {1, 8, 27, 64} is not an arithmetic sequence.

An arithmetic sequence is defined by having a constant difference between consecutive terms. To check if a sequence is arithmetic, we subtract each term from the one that follows.

The difference between 8 and 1 is 7

(8 - 1 = 7)

The difference between 27 and 8 is 19

(27 - 8 = 19)

The difference between 64 and 27 is 37

(64 - 27 = 37)

Since these differences are not equal, the sequence is not arithmetic.

There are many ways that graphs can be misleading. Depending on how you set up your graph, the same set of data can look very different. It's important to understand that there are some common mistakes to avoid when making graphs. In addition, advertisers have been known to intentionally make their graphs misleading to make their data match their point.  

In the image provided, this is a good example of a misleading graph.

First, notice that we know that the first bar is 10 and the second bar is 50. However, there are no labels on the horizontal or vertical axis so we don't know what the bars represent.

In addition, notice that there is no title on this graph. Since there is no title on the graph, we don't know anything about the data.

Further, look at the scale on the vertical axis. Notice that it's an uneven scale. The uneven scale makes it appear that the first bar is closer to the second bar than it actually is.

We could correct this graph by adding labels to the x and y-axis, adding a title to the graph, and making the scale on the vertical axis even.

Another way graphs can be misleading is using the wrong type to represent data. For example, a scatter plot might be better than a regular graph in some cases.

Lastly, graphs can be misleading by adding a wide range of numbers to show and increase or decrease relatively small to how it actually is.

Answer:

Quadrant I

Step-by-step explanation:

To find in which quadrant an angle is, you have to locate it between 0 and 360.

Since your angle is larger than 360 degrees, we subtract 360 degrees from it.... to get 27 degrees.

27 degrees and 387 degrees lie on the same spot, since they are exactly one turn around from each other.

Now, angles between 0 degrees and 90 degrees are in quadrant I

angles between 90 and 180 degrees are in quadrant II

Angles between 180 and 270 degrees are in quadrant III

Angles between 270 and 360 degrees are in quadrant IV

So, an angle of 27 degrees would land in Quadrant I.... so is 27 + 360x, where x is any integer representing a number of turns.

The answer is:

The terminal side of the angle 387° lies at the Quadrant I.

We know that there are four quadrants on the plane, those quadrants goes from 0° to 360°, however, since the quadrant is going only from 0° to 360°, if we want to know where an angle greater than 360° is located, we need to take only the excess, so:

We are asked to find where the angle 387° is located, we can write the angle by the following way:

[tex]387\°=360\°+27\°\\[/tex]

So, we have that there are 27° more than 360°, if we want to find where the 367° we only need to locate where the excess (27°) angle is located.

Also, we know that:

Quadrant I: 0° to 90°

Quadrant II: 90° to 180°

Quadrant III: 180° to 270°

Quadrant IV: 270° to 360°

We have that 27° is between 0° and 90°, so, it's located on the first quadrant.

Hence, we have that the angle 367° is located at the Quadrant I.

Have a nice day!

Answer:

16100

Step-by-step explanation:

n = 100

a1 = 15

a100 = 307

The first thing you have to do is solve for d

a100 = a1 + (n - 1)*d

307 = 15 + (100 - 1)*d

307 = 15 + 99*d

307 - 15 = 99*d

292 = 99 d

d = 292 / 99

d = 2.94949494

That's a real odd result, but it is what you get.

Sum = (a + L)*n/2

sum = (15 + 307)*n/2

Sum = 322 * 100 / 2

Sum = 16100 It looks like I didn't have to solve for d. The person who made this up sure didn't

The correct comparison for the expressions 2b and b+g is 2b > b+g.

Let's analyze the expressions:

Comparing 2b and b+g, the correct statement is A. 2b > b+g as having more green balls than blue balls implies the total green balls are more, making the expression 2b greater than b+g.

Based on these cases, the only condition that aligns with g > b is when [tex]\(2b < b + g.[/tex]

Thus, the correct answer is: B. 2b < b + g.

To find which statement is correct, let's consider the relationship between the number of green balls (g) and the number of blue balls (b). Since the bag has more green balls than blue balls, it means that g > b.

To compare the expressions 2b and b + g, let's examine their relationship under the condition g > b

When 2b > b + g

Rearranging 2b > b + g, we get:

b > g.

This contradicts the condition g > b.

So, this case is not possible.

Case 2: When 2b < b + g :

Rearranging 2b < b + g, we get:

b < g,

which aligns with the given condition g > b.

Hence, this condition is possible.

When 2b = b + g

Rearranging 2b = b + g, we get: [tex]\[b = g.\][/tex]

This condition contradicts the original requirement g > b, so this case is also not possible.

The only condition that aligns with g > b is when [tex]\(2b < b + g.[/tex] Thus, the correct answer is: B. 2b < b + g.

Answer:

5/7 quart

Step-by-step explanation:

Amount = concentration × volume

Amounts added = final amount

100% × x + 20% × 5 = 30% × (x+5)

Solving for x:

1.00x + 0.2×5 = 0.3×(x+5)

x + 1 = 0.3x + 1.5

0.7x = 0.5

x = 5/7

x ≈ 0.7

You should add 5/7 quart of pure antifreeze, or about 0.7 quart.

About 0.71 quarts of pure antifreeze should be added to 5 quarts of a 20% antifreeze solution to obtain a 30% antifreeze solution.

To find out how many quarts of pure antifreeze must be added to 5 quarts of a 20% antifreeze solution to get a 30% antifreeze solution, we can set up the following equation:

0.2 * 5 + x = 0.3 * (5 + x) where x represents the amount of pure antifreeze to be added.

Solving this equation, we get:

1 + x = 1.5 + 0.3x,

This simplifies to 0.7x = 0.5,

So x = 0.5 / 0.7,

Therefore, About 0.71 quarts of pure antifreeze should be added to get a 30% solution.

Step-by-step explanation:

Two lines intersect each other at a right angle, making them perpendicular. Thus, the resulting angles will all be 90°, making ∠4 = 90°.

Alternatively, we can use the supplementary angles equation.

Let's call the right angle marked in the picture ∠5.

∠4 + ∠5 = 180°, since the line is also a straight angle which measures 180°.

∠4 + 90° = 180°

∠4 = 90°

Either way, ∠4 = 90°
