Given: AB = 3y - 1, BC = 7y, AC = 29 Prove: AB = 8
its a normal line and the letters are in order ABC, B is kinda close to A
To prove AB = 8, we substitute the values given and show that the statement is false.
Explanation:To prove: AB = 8
Given: AB = 3y - 1, BC = 7y, AC = 29
Proof:
Since AB = 3y - 1 and AC = 29, we can substitute AC in place of AB in the equation AB = 3y - 1. This gives us 29 = 3y - 1.Simplifying the equation, we get 3y = 30.Dividing both sides of the equation by 3, we find y = 10.Substituting the value of y into AB = 3y - 1, we get AB = 3(10) - 1 = 30 - 1 = 29.Since AB = 29, we can see that AB is not equal to 8. Therefore, the given statement is false.Therefore, we cannot prove that AB = 8.

Find the measure of each indicated angle
Answer:64
Step-by-step explanation:
36+84+x=180
x=180-120
x=60
right angle 90=x+y=60+y
y=90-60=30
y+86+?=180
30+86+?=180
?=180-116
?=64
In this ordered pair (4,-5) which number is the ordinate
In the ordered pair (4, -5), the number -5 is the ordinate, which represents the vertical position of a point in a coordinate system.
In the ordered pair (4,-5), the number -5 is the ordinate. In a coordinate system, ordered pairs are used to define locations with two values: the x-coordinate and the y-coordinate. The first number in the pair represents the x-coordinate, which is the horizontal position, and the second number represents the y-coordinate, which is the vertical position, also known as the ordinate.
In this context, the ordinate is the position relative to the horizontal axis in a two-dimensional space. It indicates how far up or down a point lies from the horizontal (x) axis. Hence, in the ordered pair (4, -5), -5 is the ordinate. If a point is above the x-axis, its ordinate is positive; if it's below, as in this case, it's negative.

a cylinder. With a diameter of 6cm and a height of 10cm. Can you help me work out the volume of this cylinder to 1 decimal place please?
Final answer:
The volume of a cylinder with a diameter of 6 cm and a height of 10 cm is 282.8 cm³, calculated using the formula V = πr²h and rounding to one decimal place.
Explanation:
To calculate the volume of a cylinder, we use the formula V = πr²h where V is the volume, r is the radius of the base, and h is the height of the cylinder. In this case, we have a cylinder with a diameter of 6 cm, which means the radius r is half of that, or 3 cm. The height h is 10 cm. So, the volume is calculated by:
V = π × (3 cm)² × 10 cm
Substituting 3.142 for π, we get:
V = 3.142 × 9 cm² × 10 cm
V = 3.142 × 90 cm³
V = 282.78 cm³
Therefore, the volume of the cylinder rounded to one decimal place is 282.8 cm³.

Step-by-step explanation:
If a radical is multiplied by a number or variable, you should put the number or variable _____ the radical sign.
Final answer:
Numbers or variables are placed outside of the radical sign when multiplied by a radical. This representation indicates that the entire radical, not just the number inside, is to be multiplied by that number or variable.
Explanation:
If a radical is multiplied by a number or variable, you should put the number or variable outside the radical sign. In mathematics, multiplication or division by the same number on both sides of an equation does not change the equality. When you multiply a radical by a number or variable, you are essentially multiplying the contents inside the square root by that number or variable, but outside of the radical sign to maintain proper order of operations.
When writing an expression involving radicals mathematically, numbers or variables outside the radical do not directly interact with the values inside until simplification or further operations are performed. For example, if you're multiplying 3 by √2, you would write it as 3√2, not √(3×2). The multiplication of the coefficient (the number in front of the radical) applies to the entire radical, not just the number inside it.

The average (A) of two number,M and N, is given by the formula A=m+n/2. Find the average of the two numbers 36 and 72.
Answer: 54
Step-by-step explanation:
Average = Total/ total number
Average= 36 +72/2
= 108/2
= 54
54 is the average of the two numbers 36 and 72.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We need to find the average of the two numbers 36 and 72.
The average (A) of two number, M and N, is given by the formula A=m+n/2
Let m = 36
n=72
Now to find the average of two numbers we have to plug in these values in the formula
A=36+72/2
=108/2
=54
Hence, 54 is the average of the two numbers 36 and 72.

If sin theta = 12/13 and theta is an acute angle find cot theta
Answer:
cot θ = [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
If sin θ = [tex]\frac{12}{13}[/tex] and 'θ' is an acute angle then we have to find the value of cotθ
From the figure attached.
y² + 12² = 13² [ by Pythagoras Theorem ]
y + 144 = 169
y² = 169 - 144 = 25
y = 5
Now cot θ = [tex]\frac{base}{Height}[/tex]
= [tex]\frac{y}{12}[/tex]
= [tex]\frac{5}{12}[/tex]
Therefore, cot θ =[tex]\frac{5}{12}[/tex] is the answer.
