There are three main distinctions between AAA, ASA, and SSS:
AAA: A triangle is said to be comparable to another if any two of its three angles are equal to any two of its three angles.
ASA: According to the ASA rule, two triangles are said to be congruent if any two angles and the side located between the angles of one triangle are equal to the corresponding two angles and the side located between the angles of the second triangle.
SSS: According to the SSS rule, two triangles are considered to be congruent if all three sides of one triangle are comparable to the corresponding three sides of the other triangle.

A supermarket super shopper is defined as a shopper for whom at least 70% of the items purchased were on sale or purchased with a coupon. In the following table, income units are in thousands of dollars, and each interval goes up to but does not include the given high value. The midpoints are given to the nearest thousand dollars.
Income range 5-15 15-25 25-35 35-45 45-55 55 or more

From the given probability distribution, it is found that:
a) Yes. The events are distinct and the probabilities sum to 1.
b) The histogram is given at the end of the answer.
c) The mean is of 32.1.
d) The standard deviation is of 16.02.
What is the probability distribution?
Using the midpoint rule, the distribution is given as follows:
P(X = 10) = 0.22.P(X = 20) = 0.13.P(X = 30) = 0.21.P(X = 40) = 0.17.P(X = 50) = 0.20.P(X = 60) = 0.07.The outcomes are distinct, and their sum is of:
0.22 + 0.13 + 0.21 + 0.17 + 0.20 + 0.07 = 1.
Hence it represents a probability distribution.
The mean is given by the sum of each outcome multiplied by it's respective probability, hence:
E(X) = 10 x 0.22 + 20 x 0.13 + 30 x 0.21 + 40 x 0.17 + 50 x 0.20 + 60 x 0.07 = 32.1
The standard deviation is the square root of the sum of the difference squared between each observation and the mean, multiplied by it's respective probability, hence:
S(X) = sqrt((10-32.1)² x 0.22 + (20-32.1)² x 0.13 + (30-32.1)² x 0.21 + (40-32.1)² x 0.17 + (50-32.1)² x 0.20 + (60-32.1)² x 0.07) = 16.02.

Determine the y-intercept(b) of the line.
Substitute x₁= -4 y₁=1 and m=-4/9 into y=mx + b and solve for intercept(b).

We need to find the values of "x" and "y" from two triangles that are congruent. If the triangles are congruent it means that the corresponding angles are equal. This means that angle R and angle N are the same, and from the angle sum theorem w know that the interior angles of triangle QPR sum 180, that is mathematically:
[tex](9x-18)+84+\angle R=180[/tex]Since angle N is 3x+y, we replace that in the equation:
[tex](9x-18)+84+(3x+y)=180[/tex]Simplifying we get:
[tex]\begin{gathered} 12x+y+66=180 \\ 12x+y=180-66 \\ 12x+y=114,\text{ (1)} \end{gathered}[/tex]That gives us equation (1), but we need another equation since we have two variables. The other equation we get it from angles L and P, since this two angles must be equal. So we get the following equation:
[tex]4x+17=9x-18[/tex]Solving for "x", we get:
[tex]\begin{gathered} 4x-9x=-18-17 \\ -5x=-35 \\ x=-\frac{35}{-5}=7 \end{gathered}[/tex]The value of "x" is 7. Now we input this value in equation (1), like this:
[tex]\begin{gathered} 12x+y=114 \\ 12(7)+y=114 \\ 84+y=114 \end{gathered}[/tex]Solving for "y", we get:
[tex]\begin{gathered} y=114-84 \\ y=30 \end{gathered}[/tex]therefore, the value of "y" is 30.

Houston wants to play the "Guess your weight" game at the Strawberry Festival. If the guess is not within 10 pounds of his actual weight, Houston wins a prize. Houston weighs 102 pounds.
Write an equation to represent this situation. Use the equation to determine the greatest and least guesses that can be made without Houston winning a prize?
An equation to represent this situation is |x - 102| = 10.
The greatest and least guesses that can be made without Houston winning a prize are 112 pounds and 92 pounds.
Given:
Actual Weight of Houston = 102 pounds
Now, if the guess is not within 10 pounds of his actual weight, Houston wins a prize.
An equation to represent this situation can be written as,
|x - 102| = 10
As we know a modulus function always generates a positive value.
We need the difference between the guessed weight and the actual weight to be exactly 10 pounds so we have applied modulus in the equation.
Now we utilize the above equation to determine the greatest and least guesses that can be made without Houston winning a prize.
The greatest guessed weight will be,
x - 102 = 10 ⇒ x = 102 + 10 ⇒ x = 112 pounds
The least guessed weight will be (the modulus value will be negative in this case)
-x + 102 = 10 ⇒ x = 102 - 10 ⇒ x = 92 pounds

Mr. Salcedo was driving at a constant speed. He drove 120 3/4 miles in 3 hours. At that speed, how
many miles will he drive in 7 1/2 hour? How many miles will he drive in one hour?
He will cover 301.875 miles in 7.5 hours at a unit speed of 40.25 miles per hour.
What is unit rate?A ratio that compares two amounts of different types of units is called a rate. When a unit rate is expressed as a fraction, the denominator is 1 unit.
Rate = Distance/Time
If Mr.Salcedo was driving at 120 3/4 miles in 3 hours, his unit rate will be calculated as:
Unit rate =[120 3/4]/3
Unit rate = 483/12
Unit rate = 40 1/4 miles/hr
This shows that he drove 40 1/4 miles/hr.
The miles he drove in 7 1/2 hour is expressed as;
Miles driven = 161/4 * 15/2
Miles driven = 301.875 miles
Hence the miles that he will drive in 7.5 hours is 301.875miles and the unit rate is 40.25 miles/hr

Mark operates a small sign-making business. He finds that if he charges x dollars for each sign, he sells 37−x signs per week. What is the smallest number of signs that he can sell to have an income of $300 in one week?
The smallest number of signs that he can sell to have an income of $300 in one week is 12.
The price of one sign is x
Number of signs he sells per week = 37-x
The total earning from selling these is x(37-x) which is given as $300
(37- x) x = 300
37x - x² = 300
x² - 37x + 300 = 0
As per formula to find base in a quadratic equation
[tex]x =\frac{37 - \sqrt{37^{2}-4 . 1 . 300 } }{2 . 1} \\x =\frac{37 - \sqrt{1369-1200 } }{2} \\x =\frac{37 - \sqrt{169 } }{2} \\x = \frac{37-13}{2}\\ x = \frac{24}{2}\\ x = 12[/tex]
The other base can be
[tex]x =\frac{37 + \sqrt{37^{2}-4 . 1 . 300 } }{2 . 1} \\x =\frac{37 + \sqrt{1369-1200 } }{2} \\x =\frac{37 + \sqrt{169 } }{2} \\x = \frac{37+13}{2}\\ x = \frac{50}{2}\\ x = 25[/tex]

• He buys 6 bags of lemons that each cost the same amount.
How much does each bag of lemons cost?
Answer:
Each bag of lemons cost $3.30
Step-by-step explanation:
The equation will be
6x = 26.10 - 6.306x=26.10−6.30
Solve for x to get,
6x = 19.86x=19.8
x = 3.3x=3.3
Answer:
$3.30 for each bag of lemons
Step-by-step explanation:
We know that Omar only bought both lemons and eggs. We also know that the total amount of money he spent on groceries is $26.30 and that the eggs are worth $6.30 out of the total.
So, if we can subtract the cost of the eggs from his total cost of groceries to find how much the lemons cost. After that we can divide the cost of all the lemons, which is $19.80, by the number of bags, which is 6, to find how much each bag costs.
(26.10 - 6.30) / 6 = ?
19.8/6 = 3.30

The rectangle shown is dilated by a scale factor of 1.5 with the origin as the center of dilation.
Draw the resulting rectangle.
If the rectangle shown is dilated by a scale factor of 1.5 with the origin as the center of dilation , then the resulting rectangle is shown below .
In the question ,
From the figure given below , we can see that the coordinates of the rectangle are (4,2) , (4,4) , (-2,2) , (-2,4) .
let us name the coordinates of the rectangle as A(4,2) , B(4,4) , C(-2,4) , D(-2,2) .
and to dilate the rectangle by a scale factor of 1.5 with center of dilation at the origin , we multiply coordinates of the original shape with the dilation factor
so the rule to describe the dilation will be
(x,y)→(1.5x,1.5y)
Using this rule to find the new coordinates of the rectangle A'B'C'D' .
When A = (4,2)
A' = (1.5*4,1.5*2)
A' = (6,3)
When B = (4,4)
B' = (15*4,1.5*4)
B' = (6,6)
When C = (-2,4)
C' = (1.5*(-2),1.5*4)
C' = (-3,6)
When D = (-2,2)
D' = (1.5*(-2),1.5*2)
D' = (-3,3)
So the coordinates of the rectangle A'B'C'D' is A' = (6,3) , B' = (6,6) , C' = (-3,6) , D' = (-3,3) .
the new resulting rectangle is drawn below
Therefore , if the rectangle shown is dilated by a scale factor of 1.5 with the origin as the center of dilation , then the resulting rectangle is shown below .
