The top of a ladder is placed against the side of a house. The ladder is 15 feet long and the wall is 12 feet high. How far from the wall will the base of the ladder by positioned if the top ladder meets the top of the wall?
Answer:
9 ft
Step-by-step explanation:
The ladder is 15 feet long
The wall is 12 feet high
Therefore the distance between the base of the wall and the ladder can be calculated by applying phythagoreans theory
c^2= a^2 + b^2
15^2 = a^2 + 12^2
225= a^2 + 144
225-144= a^2
a^2= 81
a= 9 ft
Answer: A
Step-by-step explanation:
Please show any work you did and explain your answer.

Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph.
Complete Question
Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph, use their z-scores to find which dog is running faster relative to its breed
Answer:
Miniature dachshunds is faster
Step-by-step explanation:
From the question we are told that
The speed of the Miniature dachshunds is [tex]x = 14.8 \ mph[/tex]
The mean for the Miniature dachshunds is [tex]\mu_1 = 13 \ mph[/tex]
The standard deviation for the Miniature dachshunds is [tex]\sigma_1 = 1.6 \ mp h[/tex]
The speed of the Labrador is [tex]y = 25 \ mph[/tex]
The mean for the Labrador is [tex]\mu_2 = 22 \ mph[/tex]
The standard deviation for the Labrador is [tex]\sigma_2 = 2.8 \ mp h[/tex]
Generally the z-score for the Miniature dachshunds is
[tex]z_1 = \frac{x- \mu_1 }{\sigma_1}[/tex]
=> [tex]z_1 = \frac{14.8 - 13 }{1.6}[/tex]
=> [tex]z_1 = 1.125[/tex]
Generally the z-score for the Labrador is
[tex]z_2 = \frac{x- \mu_2 }{\sigma_2}[/tex]
=> [tex]z_2 = \frac{25 - 22 }{2.8}[/tex]
=> [tex]z_2 = 1.071[/tex]
From the value obtained we see that [tex]z_1 > z_2[/tex] , hence miniature dachshund is faster

If the population of a study is finite and just covers only a small set of data and the time and cost of the study is of no concern to the one who is conducting the study then it is better to take samples rather than conduct the study over the whole population
Answer:
False
Step-by-step explanation:
The above statement is not correct since the time and cost of the study is of no concern to the one who is conducting the study, The person conducting the study having ample time and resource, means that it would be better for the person to expand the scope of the study by conducting it over the whole population because that will give a more accurate result rather than conducting the study over a few samples .
Write an equation in slope-intercept form for the line that has a slope of -1/3 and passes through (-6, 1).

Step-by-step explanation:
what is the answer to this..√25x+10=15
Answer:
x = 1.
Step-by-step explanation:
√25x + 10 = 15
√25x = 15 - 10
√25x = 5
squaring both sides:
(√25x)^2 = (5)^2
25x = 25
hence x = 1.
What is the value of x?
Enter your answer in the box.
Answer:
X = 40
Step-by-step explanation:
{ 2 (x + 10)} = (3x - 30)
2x + 10 = 3x - 30
10 = 3x - 2x - 30
10 + 30 = 1x
40 = 1x
X = 40
What is an equation of the line that passes through the point (2, -5) and is parallel to the line
6x + y = 6?
The required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
First, we have to determine the slope of the line 6x + y = 6 by placing it into a slope-intercept form:
6x + y = 6 ⇒ y = -6x + 6
Therefore, the slope of the line is m = - 6
Since the required line passes through the point at (2, -5).
Let the line (y - y₁) = m(x -x₁ )
Here x₁ = 2, y₁ = -5
Substitute the values in the equation,
So, y - (-5) = -6(x - 2)
⇒ y + 5 = -6x + 12
⇒ 6x + y = 7
Hence, the required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

The bus to a science exposition averaged 18 miles to a gallon of gas.How far away was the exposition if they used 8 gallons of gas for the road trip
Answer:
144 miles
Step-by-step explanation.
If the bus has a consumption speed of 18 miles to a gallon, multiply 8 times 18 for the length of the trip!
Answer:
144 miles
Step-by-step explanation:
Distance = (fuel economy measure)(number of gallons of gas used)
Here,
Distance = (18 mpg)(8 gallons) = 144 miles

28. The difference between two
numbers is 80. If the ratio of two
numbers is 3:5, find the
numbers *
Answer:
We set up 2 equations:
n - m = 80 so "n" is the larger number
A) n - m = 80
B) m / n = .6
A) n = 80 + m
B) m = .6 n so B) n = (5/3) m
We substitute B) into A)
(5/3) m = 80 + m
(2/3) m = 80
m = 1.5 * 80
m = 120
n = 200
