The customer can afford to buy 2 whole bags of candy.

In this problem, the customer started with $52.02 in his pocket and spent $37.85 on items, leaving him with $14.17 to spend on candy. Each bag of candy costs $5.50, so the customer can afford to buy $14.17 / $5.50 = 2.6 bags of candy. However, since the customer can only buy whole bags of candy, he can only afford to buy 2 whole bags of candy. This is the final answer to the problem.

The amount of yards south that the intersection of Fort Street and Clover Street is given as follows:

450 yards.

The slope of an inclined object is obtained as the division of the vertical distance of the street by the horizontal distance of the object.

The distances are classified as follows:

The slope of the street is given as follows:

-3.

The east distance is given as follows:

150 yards.

Thus the south distance can be identified applying the slope as follows:

-3 = S/150

S = -3 x 150

S = -450 yards.

The negative number represents that the direction is south, hence the distance is only of 450 yards.

The problem is given by the image shown at the end of the answer.

Line MN is the side in between the 2 angles which are ∠LMN and ∠LNM in triangle △LMN.

An edge is a specific kind of line segment that connects two vertices of a polygon, polyhedron, or higher-dimensional polytope in geometry.

An edge, also known as a polygon side, is a line segment that forms the boundary of a polygon.

The sides of the angle are the two straight lines that unite to make it.

The intersection of two lines or rays that make an angle is known as its vertex.

So, according to the given figure, the side between ∠LMN and ∠LNM in triangle △LMN is side MN.

Therefore, line MN is the side in between the 2 angles which are ∠LMN and ∠LNM in triangle △LMN.

Step-by-step explanation:

Answer:

3 17/24

Step-by-step explanation:

2 3/8  + 1  1/3

2 3/8 = 19 /8

1 1/3 = 4/3

The common factor is 24

57/24 + 32/24 = 89/24

89/24 = 3 17/24

The correct answer is c.) the probability of getting a number less than 3 is equal to 0.33 but does not change the probability of the next trial.

The probability of getting a number less than 3 on a standard die is always equal to 0.33, regardless of the number of times the die is rolled. The probability of an event occurring does not change based on the number of times the event has occurred in the past. Each roll of the die is an independent event, meaning that the outcome of each roll does not affect the probability of the next roll.

Answer:

k = -1, 20

Step-by-step explanation:

k² - 19k - 20 = 0

k² + 1k - 20k - 20 = 0  ==> 1 * (-20) = -20   and   -20 + 1 = -19

k² + k - 20k - 20 = 0  

k(k+1) - 20(k+1) = 0   ==> factor and simplify

(k-20)(k+1) = 0

k-20=0  ==> k=20

k+1=0  ==> k=-1

k = -1, 20

Answer:

You could draw a line up the center, and it would be symmetrical.

The angle, in degrees, between the diagonal line and the left edge of the flag is 67.8 degrees.

To find the angle between the diagonal line and the left edge of the flag, you can use the Pythagorean theorem to calculate the length of the hypotenuse (the diagonal line) and one of the legs (the horizontal distance from the bottom-left corner to the end of the diagonal line). The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

The mean for a given set of observations is 6.286.

The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. A data set's mean (average) is calculated by summing all of the numbers in the set and then dividing by the number of values in the set. When a data collection is arranged from least to largest, the median is the midway value. The mode is the number that appears the most frequently in a data collection.

Here,

Step-by-step explanation: To calculate the percentage, number or ratio that can be expressed as a fraction of 100.

Pick any two pairs of equations from the system. Eliminate the same variable from each pair using the Addition/Subtraction method. Solve the system of the two new equations using the Addition/Subtraction method. Substitute the solution back into one of the original equations and solve for the third variable.

In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z)  is called an ordered triple.

To find a solution, we can perform the following operations:

Graphically, the ordered triple defines the point that is the intersection of three planes in space. You can visualize such an intersection by imagining any corner in a rectangular room. A corner is defined by three planes: two adjoining walls and the floor (or ceiling). Any point where two walls and the floor meet represents the intersection of three planes.

Answer:

Step-by-step explanation:

The value of y is unclear given the information provided. However, if BC intersects AD at E, then it stands to reason that y would be equal to the value of x. This is because, if BC intersects AD at E, then the two lines are parallel and therefore have the same value for y.

Answer:

When two pairs of corresponding angles and one pair of corresponding sides (not between the angles) are congruent, the triangles are congruent. Two triangles with one congruent side, a congruent angle and a second congruent angle.

Using the SAS(Side-Angle-Side) Theorem, ASA(Angle-Side-Angle) Theorem, SSS(Side-Side-Side) Theorem and AA(Angle-Angle) Theorem we can easily prove that two triangles are similar.

If two triangles have an equal number of comparable angles and sides, they are said to be similar.

Similar figures are items that have two or more figures with the same shape but varying sizes.

Using the SAS(Side-Angle-Side) Theorem, ASA(Angle-Side-Angle) Theorem, SSS(Side-Side-Side) Theorem and AA(Angle-Angle) Theorem we can easily prove that two triangles are similar.

A portion on one polygon must correspond perfectly to a part in another polygon that is in a similar place. Even though two triangles are oriented differently from one another, you can conclude that their angles match if you can spin them to align in the same direction and notice that their angles are similar.
