Yes, the numbers will be similar.

it will be true if the numbers were -3, 5, -16 and -10

Explanation:

The first list: -3, 5, 16 and -10

Arranging from least to greatest:

-10, -3, 5, 16

Arranging the same numbers from closest to zero to farthest to zero:

Let's use zero as our reference. Then start arranging towards the left and right side of it.

-10, -3, 0, 5, 16

Looking at the above: when we remove 0, we would have same answer as the arrangement from least to greatest:

-10, -3, 5, 16

The second list:

-3, 5, -16, -10

Arranging from least to greatest:

-16, -10, -3, 5

Arranging the same numbers from closest to zero to farthest to zero:

Let's use zero as our reference. Then start arranging towards the left and right side of it.

-16, -10, -3, 0, 5

Looking at the above: when we remove 0, we would have same answer as the arrangement from least to greatest:

-16, -10, -3, 5

Hence, fromt the above: if we arrange the same numbers from least to greatest and from closest to zero to farthest to zero, we would arrive at the same result.

Answer:

B. the amount spent on grapes compared with the weight of the purchase

Answer:

Answer:

x = 3

Step-by-step explanation:

When twenty is reduced by one-third of a number, the result is 19. Find the number.

20 - 1/3x = 19

subtract 20 to both sides:

20 - 1/3x - 20 = 19 - 20

-1/3x = -1

multiply both sides by -3:

-3(-1/3x) = -1(-3)

x = 3

Given the two numbers, let us simplify to find the value;

From the derived value, we can find which of the statements is true.

From the options, we can see that the only option that is entirely true is;

- The value of root 17 is less than 5, and the value of root 60 is greater than 7.

In an arithmetic sequence, the consecutive terms differ by a common difference. This means that the second term minus the first term would be equal to the third term minus the second term. The pattern continues.

Looking at the sequence, the common difference is

3 3/4 - 4 = 3 1/2 - 33/4 3 1/4 - 3 1/2 = - 1/4

The next term after 3 1/4 would be 3 1/4 + - 1/4 = 3 1/4 - 1/4 = 3

The next term after 3 would be 3 + -

It will take 4.9 days for 21 locust to eat 420 grams of grass

From the question, we have the following parameters:

Given that the amount of grass is constant at 420 grams

The given parameters can be represented using the following ratio

Ratio = Locust : Days

So, we have

Locust : Days = 30 : 7

When there are a total number of 21 locust eating the grass, then we have

21 : Days = 30 : 7

Express as fraction

Days/21 = 7/30

This gives

Days = 21 * 7/30

Evaluate

Days = 4.9

Hence, the number of days is 4.9 days

AA (or AAA) or Angle-Angle Similarity

If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.

We do not have 3 angles.

SAS or Side-Angle-Side Similarity

If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar.

We have two sides and 1 angle. But, two sides of a triangle are not in the same proportion of the two sides of another triangle

SSS or Side-Side-Side Similarity

If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.

Answer:

[tex](x-1)^2+(y-9)^2=3^2[/tex]

Step-by-step explanation:

The standard form of the equation of a circle is:

[tex](x-a)^2+(y-b)^2=r^2[/tex]

Where a and b are the x and y, coordinates, and r is the radius.

So, you can just substitute the a and b values for the x and y values of the center to find the equation of the circle.

For k=2 for infinite solutions.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

4(4x + 1) = k(8x + 2)

Now, the equation should have infinite solutions

In consider the situation then we must put value of k such that LHS part become Equal to RHS.

Now, take k=2

4(4x + 1) = k(8x + 2)

LHS: 4(4x+1)= 16x+ 4

RHS: 2(8x+ 2)= 16x+ 4

Hence, k=2 for infinite solutions.

The secant function is the reciprocal of the cosine function.

We can evaluate trigonometric functions of angles outside the first quadrant using reference angles as we have already done with the sine and cosine functions. The procedure is the same:

Find the reference angle formed by the terminal side of the given angle with the horizontal axis. The trigonometric function values for the original angle will be the same as those for the reference angle, except for the positive or negative sign, which is determined by x– and y-values in the original quadrant. (Figure) shows which functions are positive in which quadrant.

An even function is one in which f(-x) = f(x)

An even function is one in which f(-x) = - f(x)

Cosine and secant are even:

Therefore from the drop down the correct answer : secant function is EVEN

The formula for determining the surface area of a sphere is expressed as

Surface area = 4 * pi * radius^2

From the information given,

surface area = 6

pi = 3.14

thus,

6 = 4 * 3.14 * radius^2

6 = 12.56radius^2

The formula for determining the volume of a sphere is expressed as

Volume = 4/3 * pi * radius^3

Thus,

Volume of sphere = 4/3 * 3.14 * 0.69^3

Volume of sphere = 1.38m^3

The lcm of the rational algebraic equation 6/x+x-3/4=2 be (24 -3x - 4x²) / 4x = 0.

The least common multiple is defined as the set of numbers with the least common multiple. The lowest positive integer with more than one factor in the set is HCF.

The given equation below as:

⇒ 6/x + x - 3/4 = 2

We must find the lcm of the rational algebraic equation.

⇒ 6/x + x - 3/4 = 2

Rearrange the term of 2 in the equation,

A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)

In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:

(x - h)² + (y - k)² = r²

Where:

Then, we need to apply the following rigid transformations:

Translation

f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.

Dilation with center at the center of the circle

r → k · r, where k is the scale factor.

The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:

f(x, y) → f(x + 5, y - 2)

(x + 5)² + (y - 2)² = 9

r → k · r

(x + 5)² + (y - 2)² = (1 / 3)² · 9

(x + 5)² + (y - 2)² = 1

Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.
