Answer:

than twice the smaller number, what are the numbers?

Let's call the smaller number x and the larger number y. We know that x + y = 58 and y = 2x - 10. We can substitute the second equation into the first to get x + (2x - 10) = 58. Combining like terms, we get 3x - 10 = 58, which means that x = 24. Plugging this back into the equation y = 2x - 10, we get y = 48. So, the two numbers are 24 and 48.

The distance left after 3 hour's drive is 20 miles.

An equation is a mathematical statement of two expressions connected by an equal sign.

We have.

d = 125 - 35t

d is the distance left after traveling t hours.

Now,

t = 3.

d = 125 - 35 x 3

d = 125 - 105

d = 20

Thus,

The number of miles left after 3 hour drive is 20 miles.

In solving the equation, the student did the division wrong, and 29.4/4.2 = 7 which is correct.

Multiplication is the opposite of division.

If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.

Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

So, the equation is:

4.2p = 29.4

Let's solve as follows:

4.2p = 29.4

p = 29.4/4.2

p = 7

So, the value of p comes to 7.

Where in the image, the value of p is 123.48 which is wrong as the division is not done properly.

37. The equation m/5 = 50 can be used to describe how much money a quintet has to earn in order for each member to receive $50. In this equation, the variable m represents the total amount of money the quintet earns, and the number 5 represents the number of members in the quintet. The expression m/5 represents the amount of money that each member of the quintet receives, and the number 50 represents the target amount of money each member should receive.

The equation states that if the quintet earns a total of m dollars, then each member will receive m/5 dollars, which should be equal to 50 dollars. Therefore, this equation can be used to find the total amount of money the quintet needs to earn in order for each member to receive $50.

38. To estimate the solution of the equation 12x=-38, we can use the equation x=-38/12. This equation states that the solution of the given equation is equal to the negative of 38 divided by 12.

To apply the distributive property using the greatest common factor (GCF) to write an equivalent expression for 0.3x - 2.7, we need to find the GCF of the coefficients of the terms in the expression. In this case, the GCF is 0.3, so we can write the expression as 0.3(x - 9). This is an equivalent expression to 0.3x - 2.7, because multiplying 0.3 by the difference of x and 9 produces the same result as subtracting 2.7 from 0.3x.

The statement, "If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z" demonstrates: D. the transitive property.

In geometry, the transitive property of congruency states that when two angles, sides, or triangles are congruent to a third angle, side, or triangle, then all three angles, sides, or triangles will be congruent to each other.

Illustrating the transitive property, if a = b, and b = c, therefore, a = b = c. We can then state that a = c.

Therefore, given that If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z, we have:

Two angles, X and Z, which are both congruent to a third angle, Y.

Therefore, based on the transitive property, we can state that all three angles are congruent to each other, which leads us to conclude that:

m∠X ≅ m∠Z.

Answer:

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree (which comes from the exponent on the leading term) and the leading coefficient (+ or –) of a polynomial function determines the end behavior of the graph.

Step-by-step explanation:   hope this helps!

The function approaches negative infinity as x approaches positive infinity and the function approaches negative infinity as x approaches positive infinity. Option C is correct.

The end behavior of a polynomial function describes the behavior of the function as x becomes very large in either the positive or negative direction.

As x approaches negative infinity, the function becomes more and more positive. As x approaches positive infinity, the function becomes more and more negative.

As x → -∞, y → ∞

As x → +∞, y → -∞

Answer:

To find the value of the quartiles, we need to first find the median of the data set. The median is the middle value of the data set, or the value that separates the lower half of the data from the upper half. In this data set, the median is 2.5, as it is the middle value when the data is arranged in ascending order.

Once we have the median, we can find the first and third quartiles. The first quartile, also known as Q1, is the median of the lower half of the data set, and the third quartile, also known as Q3, is the median of the upper half of the data set. In this data set, the lower half of the data is {1.3, 1.5, 1.7, 2, 2.5}, and the upper half of the data is {2.7, 2.9, 3, 3.1}. The median of the lower half is 1.7, and the median of the upper half is 2.9.

Therefore, the value of the quartiles is Q1 = 1.7, Q2 = 2.5, and Q3 = 2.9.

The angles in the parallel lines are as follows;

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, linear angles, vertically opposite angles etc.

Therefore, let's find the angles m∠1 and m∠2.

Hence,

138 + m∠1 = 180(angles on a straight line)

The sum of angles on a straight line is 180 degrees.

m∠1 = 180 - 138

m∠1 = 42 degrees

Therefore,

m∠1 =  m∠2 (alternate exterior angles)

Alternate exterior angles are the pair of angles that are formed on th outer side of the parallel lines but on the opposite side of the transversal.

Alternate exterior angles are congruent.

Therefore,

m∠1 =  m∠2 = 42 degrees.

volume of cone = [tex]\frac{1}{3}[/tex]r²[tex]\pi[/tex]h

r = 4 feet

Put in your values:

[tex]\frac{1}{3}[/tex](4)²(3.14)h = 189 ft³

16(3.14)h = 567

50.24h = 567

h = [tex]\frac{567}{50.27}[/tex] = 11.3

The height of the cone is h = 11.3 feet

In geometry,  a cone is a three-dimensional shape formed by joining a set of line segments from a common point called apex to all the points of the base which is a circle.

Height of the cone is distance from apex to the center of the circular base.

Volume of a cone is defined as the total capacity of the cone and the formula for the same is given by,

V = [tex]\frac{1\\}{3}[/tex]πr²h

Here, V = 189 ft³, r = 4 ft, π = 3.14

Substituting these values in formula for the volume,

189 = [tex]\frac{1}{3}[/tex] × 3.14 × 4² × h

189 = [tex]\frac{50.24}{3}[/tex]h

h = 189 × 3 / 50.24

h = 11.285 ≈ 11.3

Hence the height of the cone with radius 4 ft and volume 189 ft³ to the nearest tenth of a foot is 11.3 ft.
