If an equilateral triangle has a side lengths of 8 units , what is the height of the triangle
Answer:
8
Step-by-step explanation: each side is equal so 8
The height of the equilateral triangle for the given side length is equal to ( 4√3 ) units or approximately 6.93 units (rounded to two decimal places).
In an equilateral triangle, the height is the line segment perpendicular to one side of the triangle and passing through the opposite vertex.
For an equilateral triangle with side length "s," the height "h" can be calculated using the formula:
h = ( √3 / 2) × 8
Where "s" is the side length of the equilateral triangle.
Here, the side length of the equilateral triangle is given as 8 units.
So, substituting the value of "s" into the formula:
⇒ h = ( √3 / 2) × 8
⇒ h = ( 8√3 / 2)
⇒ h = ( 4√3 ) units
Therefore, the height of the equilateral triangle is ( 4√3 ) units or approximately 6.93 units (rounded to two decimal places).

How many miles does the first cyclist bike in 45 minutes?
Answer: 9 miles
Step-by-step explanation: 12 mph/60 so you can get mpm(miles per minutes)
Multiply the 0.2x45 (0.2 from 12/60 and 45 from how long the first biker had ridden on his bike)

find the value of p
Answer:
Let's take the angle LEFT to p to be "x".
80+30+x = 180
110+x = 180
x = 70
Finding p:
90+70+p = 180 (REASON: linear pair)
160+p = 180
p = 20
THEREFORE, THE VALUE OF 'p' IS 20°

What is the image point of (0,9) after a translation left 1 unit and down 2 units?
Answer:-1,7
Step-by-step explanation:
The point after translation left 1 unit and down 2 units will be (-1, 7)
What is translation?A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system.
Given that, a point (0,9) is being translated left 1 unit and down 2 units
We know that, translation rule for, left and down is,
(x, y) = (x-a), (y-b) where a and b are units by which points are being translated.
Therefore,
(0, 9) = (0-1, 9-2)
= (-1, 7)
Hence, the point after translation left 1 unit and down 2 units will be (-1, 7)

A population of values has a normal distribution with μ=152.8 and σ=26.2 . You intend to draw a random sample of size n=94 . Find the probability that a single randomly selected value is less than 149.6. P(X < 149.6) =
Answer:
P(x < 149.6) = 0.11821
Step-by-step explanation:
We start by calculating the z-score of the parameter given
Mathematically,
z-score = (x-mean)/SD/√n
z-score = (149.6-152.8)/26.2/√94
z-score = -3.2/2.70
z-score = -1.18
So the probability we want to calculate is;
P( x < -1.18)
we can use the standard normal distribution table to get this
From the standard normal distribution table, this value is 0.11821
What is the vertex of the graph?
Answer:
The point (x, y) → (-5, 0) is the vertex of the graph.Step-by-step explanation:
As the given graph represents Parabola
As we know that Parabolas always contain the lowest point, or the highest point if any given parabola is upside-down. This lowest or highest point is the location where the parabola tends to change its direction and called the 'vertex'.Hence, from the given graph, we can easily determine that the parabola changes its direction at x = -5, and y = 0.
Therefore, the point (x, y) → (-5, 0) is the vertex of the graph.Teddy has two sisters. One of them is 3 years younger than Teddy, the other one is 7 years younger than her only brother. How old was the older sisters when the younger sister was born?
Given:
Teddy has two sisters. One of them is 3 years younger than Teddy, the other one is 7 years younger than her only brother.
To find:
The age of older sister at the time when the younger sister was born.
Solution:
Let the age of Teddy be x.
One sister is 3 years younger than Teddy.
Age of one sister = x-3 years
The other one is 7 years younger than her only brother. It means other sister is 7 years younger than Teddy.
Age of other sister = x-7 years
Clearly (x-3) > (x-7). So, difference between the ages of sisters is
[tex]Difference=(x-3)-(x-7)[/tex]
[tex]=x-3-x+7[/tex]
[tex]=4[/tex]
Therefore, the age of older sister is 4 years when the younger sister was born.
