The length of line segment CB is 5 units.
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].
Given that, A=(8, 15), B = (12, 13) and C = (8, 10)
Here, substitute (x₁, y₁)= (8, 10) and (x₂, y₂)=(12, 13) in distance formula, we get
CB = √[(12-8)²+(13-10)²]
= √(4²+3²)
= √(16+9)
= √25
CB= 5 units
Therefore, the length of CB is 5 units.

After the dimensions of an equilateral triangle are increased by a scale factor of 2.5, the perimeter is 45 units. What were the side lengths of the original triangle?
Answer:
Original side of triangle = 6 units
Step-by-step explanation:
Given:
Perimeter = 45 units
Scale factor = 2.5 (Increase)
Find:
Original side of triangle = ?
Computation:
Original Perimeter = Perimeter / Scale factor
Original Perimeter = 45 units / 2.5
Original Perimeter = 18 units
Perimeter of an equilateral triangle = 3 (Side)
18 units = 3 (Side)
Side = 6 units
Original side of triangle = 6 units

What is the area of the base of a cylinder with a volume of 174π in.3 and a height of 12 inches?
Answer:
The area of the base is 14.5π in²
Step-by-step explanation:
The volume of a cylinder is given by
Volume =base\:area \times height
Or
V=Bh
It was given that the volume of the cylinder is 174π in³.
The height was given as 12 inches.
We substitute to get,
174π=12B
Divide both sides by 12 to get:
B=14.5π in²
Hence the area of the base is 14.5π in²
Hope this helpsBrainliest plzand have a wonderful dayAnswer:
area of base = 14.5π in²
Step-by-step explanation:
the area of the base of a cylinder with a volume of 174π in^3 and a height of 12 inches is found by applying the formula for the volume of a cylinder:
V = πr²h
Here the area of the base of a cylinder with a volume of 174π in³ and a height of 12 inches, and so:
V = πr²(12 in) = 174 π in³
Dividing both sides by 12 in isolates πr², which is the area of the base:
174π in³
area of base = πr² = --------------- = 14.5π in²

Exactly 1 solution
Step-by-step explanation:
First we must disrupte3y+27=12y+13
Next we switch one number to the other side27=9y+13
Now we must switch the other number14=9y
Now we must solve by dividing 14 by 9y=1.555
This is one solution, so we now have our answer.
The equation has only one solution. Then the correct option is A.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equations are given below.
3y = -6x + 9
y = -2x + 3 ...1
y = -6x + 9 ...2
From equations 1 and 2, then we have
-2x + 3 = -6x + 9
4x = 6
x = 6/4
x = 1.5
Then the value of the variable 'y' is calculated as,
y = -2x + 3
y = -2(1.5) + 3
y = - 3 + 3
y = 0
The solution of the equation y = -2x + 3 and y = -6x + 9 will be (1.5, 0). Then the equation has only one solution. Then the correct option is A.

Answer:
$3690
Step-by-step explanation:
Let's first find what percent of the original price it is being sold for.
100%-18%=82%
The water cooler is being sold for 82% of its original price.
Let's now find 82% of 4500.
0.82*4500=3690
The selling price is $3690
Answer:
3690
Step-by-step explanation:
the original price is 4500
for decreasing or discount we use this formula x discount upo 100 multiply by the original price. so for this question if we apply the formula it will be
18upon 100 x4500. the answer comes as 810. noww we subtract the original price from the discounted price. so 4500-810=3690. comes as ur selling price

The playing field for a particular sport is a rectangle whose length is 4 feet more than twice the width. The perimeter of the playing field is 200 feet. Find the dimensions of the playing field.
Answer:
The length and width of the field are 68ft and 32ft respectively
Step-by-step explanation:
Given:
Rectangular Playing Field
Perimeter. P = 200 ft
Required
The dimension of the field (Length and Width)
Let L and W represent the length and the width of the field.
From the question, L is 4 more than twice of W.
This means
L = 4 + 2W
Provided that the playing field is rectangular in shape;
We need to make use of the formula of perimeter of a rectangle.
P = 2(L + W)
Substitute 200 for P
200 = 2(L + W)
Divide through by 2
[tex]\frac{200}{2} = \frac{2(L + W)}{2}[/tex]
100 = L + W
Recall that L = 4 + 2W
Substitute 4 + 2W for L
100 = L + W becomes
100 = 4 + 2W + W
100 = 4 + 3W
Subtract 4 form both sides
100 - 4 = 4 + 3W - 4
96 = 3W
Divide both sided by 3
[tex]\frac{96}{3} = \frac{3W}{3}[/tex]
32 = W
W = 32
Recall that L = 4 + 2W
Substitute 32 for W
L = 4 + 2(32)
L = 4 + 64
L = 68
Hence the length and width of the field are 68ft anf 32ft respectively

What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
An inequality,
|x-4| < 3.
Simplifying,
-3 < x - 4 < 3
Adding 4 to all sides,
1 < x < 7
Therefore, the solution is 1 < x < 7.
