A horse galloped along seven and three sevenths miles of trail. There were hurdles spaced evenly throughout the trail every four sevenths of a mile. How many hurdles did the horse jump?
Answers
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.
Brian opens a new savings account, with an annual interest rate of 3. 5%. If his initial deposit is gbp 3000, write an expression for his savings, s, after t years.
Answers
The expression for savings after t years, based on the principle amount and annual interest rate is 3000 + 105t.
The formula to be used for computation of savings is -
Interest = (Principal × Rate of interest × Time)/100
Keep the values in formula -
Interest = (3000 × 3.5 × t)/100
Performing division and multiplication
Interest = 10,500t/100
Performing division on Right Hand Side of the equation to find the interest
Interest = 105t
Now, savings will be sum of amount and the interest earned
Savings = 3000 + 105t
Thus, the savings will be 3000 + 105t.

the number of widgets that a manufacturing plant can produce varies jointly as the number of workers and the time that they have worked. find the constant of proportionality k to 2 decimal places if 675 workers work 3 hours and can produce 11198.25 widgets.
Answers
If 675 workers work for 3 hours and can produce 11198.25 widgets then the constant of proportionality is 5.53 .
In the question,
it is given that ,
the number of widgets production varies with the number of workers and the time that they have worked ,
let the number of workers be "w" and
let the number of time they worked be "t" ,
let the number of widgets produced be "n".
So , the equation becomes
n ∝ w × t
n = k × t × w
Substituting the values of w = 675 , t = 3 and n = 11198.25
we get ,
11198.25 = k × ×675 × 3
k = 11198.25/2025
k = 5.53
Therefore , the constant of proportionality is 5.53 .

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the event's impossibility and 1 indicates certainty. An event's likelihood of occurring increases with its probability.
now , let D = depart on time and A = arrives on time

call a 33-digit number geometric if it has 33 distinct digits which, when read from left to right, form a geometric sequence. find the difference between the largest and smallest geometric numbers.
Answers
The difference between the largest and smallest geometric numbers is 840.
Assume that the largest geometric number starts with a 9.
We know that the common ratio must be a rational of the form k/3 for some integer k, because a whole number should be attained for the 3rd term as well. When k = 1, the number is 931.
When k = 2, the number is 964. When k = 3, we get 999, but the integers must be distinct.
By the same logic, the smallest geometric number is 124.
The largest geometric number is 964 and the smallest is 124. Thus the difference is 964 - 124 = 840.
Hence, the difference between the largest and smallest geometric numbers is 840.

What expression represents the length of the rectangle?
Answers
By using the quadratic equation that can be written with the given information:
x² -7x + 10 = (x - 5)*(x - a)
We will see that the length is:
L = x - 2
How to get the length of the rectangle?Remember that for a rectangle of length L and width W, the area is given by the product:
A = L*W
Here we know that:
The area is: x² -7x + 10
The width is: x -5
The length will be another factor of the quadratic equation, and we know that it should be of the form:
(x - a)
Using the area formula, we will get:
x² -7x + 10 = (x - 5)*(x - a)
Expanding the right side we get:
x² -7x + 10 = x² -5x -ax + 5a
x² -7x + 10 = x² + (-5 - a)*x + 5a
Comparing like terms, we can see that:
-5 - a = -7
5a = 10
The solution of both of these is:
a = 7 - 5 = 2
a = 10/5 = 2
