Answer:
13 Hurdles
Step-by-step explanation:
If a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile then there are 13 such hurdles after solving all the fractions.
Given that a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile.
We are required to find the number of hurdles. All the values are given in fractions.
Ability of horse to gallop=7+3/7
=(49+3)/7
=52/7
Distance between two hurdles=4/7
Number of hurdles=52/7/4/7
=52*7/4*7
=52/4
=13 hurdles
Hence if a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile then there are 13 such hurdles after solving all the fractions.

Henry is standing 4 feet from the base of a tree in his yard. The tree is 14 feet tall. What is the angle of elevation the point on the ground where he is standing, to the top of the tree? Round to the nearest tenth?
Answer:
Here
Step-by-step explanation:
54.5°
Answer:
63.4
Step-by-step explanation:
First, find the height of the tree relative to Henry by subtracting his height from the tree's height: 14 feet - 4 feet = <<14-4=10>>10 feet
Next, use the formula for finding the angle of elevation: tan(angle) = opposite side / adjacent side
Since the opposite side is the tree's height relative to Henry and the adjacent side is the distance between Henry and the tree, plug in the values: tan(angle) = 10 feet / 4 feet
Solve for the angle: tan(angle) = 2.5
Since the inverse tangent function is used to find the angle given the tangent value, find the inverse tangent of 2.5: angle = tan^-1(2.5) = 63.4 degrees
Round to the nearest tenth: 63.4 degrees rounded to the nearest tenth is 63.4 degrees. Answer: {63.4}.

I need the 500th term of the 7 count sequence 24,31,38,45,52
The 500th term of the 7 count sequence 24,31,38,45,52 is 3517.
How to calculate the sequence?It should be noted that this is an arithmetic sequence. The formula is represented as:
a + (n - 1) d
where
a = first term
n = number of terms
d = common difference
Since the numbers are 24,31,38,45,52, the common difference is (3 - 25) = 7
The 500th term will be:
a + (n - 1) d
24 + (500 - 1) × 7
= 24 + (499 × 7)
= 24 + 3493
= 3517

What is combination?
A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

Barry has a medical plan with a $1,000 deductible, 20% coinsurance, and a $5,000 coinsurance cap. His allowable medical expenses during the past year are $18,000. How much of this amount will he have to pay out of pocket?.
Based on his deductible and coinsurance cap, the amount that Barry will pay is $4,560.
Barry will pay x amount.
Barry will be responsible for covering the entire $1,200 deductible. The remaining costs will subsequently be split between him and the insurer in a ratio of 20% to 80%, although he will not be required to pay more than $5,000.
He will consequently pay the following total out of pocket:
= Deductible + ( 20% x (Medical expenses - deductible)
Solving gives:
= 1,200 + ( 20% x (18,000 - 1,200))
= $4,560
He will pay $4,560 in total.

The complete statement is:
In ΔFGH, the measure of m∠F=54°, the measure of m∠G=90°, and m∠H = 36°
How to complete the missing blank?From the question, we have the following parameters that can be used in our computation:
Triangle = ΔFGH, The measure of m∠F = 54°The measure of m∠G = 90°The sum of angles in a triangle is 180°
So, we have the following representation
m∠F + m∠G + m∠H = 180°
Substitute the known values in the above equation, so, we have the following representation
54 + 90 + m∠H = 180°
Evaluate the sum in the above equation
This gives
144 + m∠H = 180°
Collect the like terms
m∠H = 180 - 144°
So, we have

The total cost of the engagement ring is $10,975. The sales tax is calculated as follows: $10,000 x 0.0975 = $975.
Why does sales tax matter?A sales tax is a type of consumption tax that local or state governments apply on the sale of products or services that consumers pay for when they make a purchase. When a company has a link to the jurisdiction in some way, it is responsible for collecting sales tax and remitting payment to the government.
How is sales tax collected?It is only imposed and paid when the taxable supply is produced while engaging in a "taxable activity". Taxes should be based on the value of the goods or service. Because of the way the sales tax is structured, consumers are required to bear the majority of the tax burden. Because sales tax is an indirect tax, this is true.

Lines l and m are parallel.
Which statement is always true?
Group of answer choices
A 90° rotation will map line l onto line m.
Line l can be reflected over a horizontal line to map onto line m.
Line l can be reflected over a vertical line to map onto line m.
Line l can be translated to map onto line m.
Lines l and m are parallel; line l will map onto line m with a 90° rotation; line l can map onto line m with a vertical line of reflection.
Do you have any explanations as to why the lines L and m are parallel?L and m are not parallel because the sum of the co-interior angles on the same side of the transversal does not equal 180 degrees.In the event when two lines, l and m, are in the same plane but do not cross, they are said to be parallel.We are aware that the equivalent angles are equal if they are parallel and a transversal is drawn to intersect them both. Accordingly, these are x and y. As a result, we can conclude that x and y are equivalent if l and m are parallel.If two lines, l and m, are in the same plane and do not cross one another, then they are parallel.To learn more about Lines refer to:

A random variable x has a mean of 120 and a standard deviation of 15. A random variable y has a mean of 100 and a standard deviation of 9. If x and y are independent, approximately what is the standard deviation of x - y ?.
The standard deviation of x - y is 12
X and Y are independent random variables
For random variable X, mean =120 and standard deviation =15
For random variable Y, mean =100 and standard deviation = 9
Let D be the difference of standard deviation of X and Y.
Variance can be defined as the square of standard deviation.
Hence, Variance of X = (standard deviation of X)2 = (15)2 = 225
And, variance of Y = (standard deviation of Y)2 = (9)2 = 81
SD(X - Y) = sqrt(SD(X)2 - SD(Y)2)
Hence, D = sqrt(225 - 81) = sqrt(14) = 12
Hence, the standard deviation of x - y is 12

They will be at the same altitude in minutes, when their altitude will be feet.
The time at which the planes are at the same height is given as 6 minutes.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The expression for the height of the two airplanes in terms of time t is given as,
For the first airplane it is 35400 - 3300t,
And, for the second it is 2600t.
When, the two airplanes are at the same height the following equation can be written,
35400 - 3300t = 2600t
=> 35400 = 3300t + 2600t
=> 5900t = 35400
