An unlimited number of acute triangles can be formed from two sides without an angle measurement, such as a = 10 m and b = 10 m.
As an illustration -
If our side lengths are 10m and 10m, and our angle value goes from 0 to 90 degrees, how many different acute triangles can we create?
Construct a triangle with sides of 10 and 10 metres, an angle of 45 degrees, and a third side that can be extended to the desired length. You have built a triangle.
By changing the third side's length and angle, we can make a whole different triangle that is identical to this one.
Never forget to choose the side lengths and angles. There is a suggestion that you might decide to take a different step. The same angles can be used to make an unlimited number of different triangles.
As a result, with a single angle and a single side length, we can create an endless number of triangles.

your bank gives you 50 points for monthly online bill pay, 50 points for monthly mobile deposits, 100 points per car payment, and 1.5 points per dollar credit card spent. You had monthly credit card charges of $1,400 last month. You earn $75 per 10,000 points. How much in dollars did you earn from points last month?
a) $17.25
b) $23.50
c) $75.00
d) $200.00
The amount that you earned last month would be the total of $17.25
How to solve for the earningWe have the following data
online pay bill per month = 50
The monthly online deposit = 50
The points that are made per car payment = 100
The point that is made per credit card = 1.5 points
The monthly credit card charges of $1,400
The monthly point would be 1400 * 1.5 = $2100
We have to solve for the total points
= 50 + 50 + 100 + 2100
= 2300
We have $75 per 10,000
For 2300 points, this would be 75/10000 * 2300
= $17.25
Hence the amount that is made in dollars from the points in the last month is $17.25

Suppose you work for a packaging company and are designing a box that has a rectangular bottom with a perimeter of 36 cm . The box must be 4cm high. What dimensions give the maximum volume?
b. What information can you get from the function to find the maximum volume?
The dimension that give the maximum volume will be the sides.
The volume will be 324cm³.
How to calculate the value?It should be noted that the maximum value is when the rectangle is a square.
Let s be the side of the square.
The perimeter will be 4s.
Solving for s:
= 36/4
= 9cm
It should be noted that area = s²
where s = side
= 9² = 81cm
Therefore, the volume will be
= Area × Side
= 81 × 4

A 30-foot ladder is leaning against a building. The base of the ladder is 18feet from the side of the building. How high does the ladder reach along the side of the building? The ladder reaches _____ feet high on the building.
Answer:
Step-by-step explanation:
a² + b² = c²
18² + b² = 30²
324 + b² = 900
b² = 576
b = 24
Answer: 24
Step-by-step explanation: you use the formula: a^2 + b^2 = c^2. If you drew a picture, it would form a triangle with 30 as the length of the hypotonuse, and 18 as one of the legs. This given, we would have a^2 + 18^2 = 30^2 (hypotonuse = c) Then, solve.

The length of a rectangle is 3 meters more than the width. The perimeter of the rectangle is 26 meters. If the width is b, which equation represents the situation? How many solutions will this equation have?
Answer Choices:
A. (b + 3)(b) = 26, which has one solution
B. 2(b + 3) + 2b = 26, which has infinitely many solutions
C. 2[(b + 3) + b] = 26, which has one solution
D. 2[(b + 3) + b] = 26, which has no solution
The equation which represents the situation is 2[(b + 3) + b] = 26 and the equation has one solution.
The correct answer option from above is option C
What is meant by the perimeter of rectangle?The perimeter of a rectangle is the addition of all the sides of the rectangle, that is, the addition of the two length and two width.
Width of the rectangle = bLength of the rectangle = (b + 3)Perimeter of the rectangle = 26 metersPerimeter of the rectangle = 2(length + width)
26 = 2{(b + 3) + b}
26 = 2(b + 3 + b)
26 = 2(2b + 3)
open parenthesis26 = 4b + 6
Then substract 6 from both sides26 - 6 = 4b
20 = 4b
b = 20/4
b = 5
Width of the rectangle = b
= 5 meters
Length of the rectangle = (b + 3)
= (5 + 3)
= 8 meters
So therefore, length and width of the rectangle given the perimeter is 8 meters and 5 meters respectively.

The mean test score of 10 students is 50 marks.
A student joins the class.
The mean of all 11 students is now 55 marks.
Find the test score of the student who joined the class.
Answer:
105.
Step-by-step explanation:
Total score for 10 students = 50 * 10 = 500.
When 1 student joins:
mean score = (500 + x) / 11 = 55 where x is the test score of the new student.
500 + x = 55 * 11
x = 55*11 - 500
= 605 - 500
= 105.
In the given case , we can conclude The test score of the student who joined the class is 105 marks.
Let's solve this problem step by step:
The mean test score of the first 10 students is 50 marks. Therefore, the total marks scored by these 10 students is 10 x 50 = 500 marks.
When the new student joins, the mean score of all 11 students becomes 55 marks.
Therefore, the total marks scored by all 11 students is 11 x 55 = 605 marks.
To find the test score of the new student, we subtract the total marks of the first 10 students from the total marks of all 11 students: 605 - 500 = 105 marks.
Therefore, the test score of the student who joined the class is 105 marks.

What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
x < –3
x > –3
x < 3
x > 3
==================================================
Explanation:
We need to divide both sides by -2 to fully isolate x.
Dividing both sides by a negative number will flip the inequality sign
We go from -6 < -2x to 3 > x
Then we flip 3 > x to x < 3 which is choice C
-----------------
A slightly longer approach:
-6 < -2x
-6+2x < 0 .... add 2x to both sides
2x < 6 .... add 6 to both sides
2x/2 < 6/2 .... divide both sides by 2
x < 3
We get the same answer as the previous section. It helps show why the sign flip happened when dividing both sides by a negative number.

How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 980) and (12, 800)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (980 - 800)/(6 - 12)
Evaluate
Rate = -30
This means that the rate of change is -$22.5
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = -30
So, we have
y = -30(x - x1) + y1
Using one of the points, we have
y = -30(x - 6) + 980
Set x = 0
So, we have
y = -30(0 - 6) + 980

The sum of three consecutive integers is -48 then the least of the three integers is -16.
What is meant by consecutive numbers?Consecutive numbers are numbers that follow each other in descending order from smallest to largest.
Consecutive numbers are those that come after each other in descending order from the smallest to the largest. The difference between consecutive numbers is always fixed and follows a predictable pattern.
The numbers are x-1, x, and x+1.
(x-1) + (x) + (x+1) = -48
simplifying the above equation, we get
x - 1 + x + x + 1 = -48
x + x + x + 1 - 1 = -48
3x + 1 - 1 = -48
3x = -48
Dividing throughout by 3, we get
x/3 = -48/3
x = -16
