40 miles
Step-by-step explanation:
Step one:
given data
let the total distance to be covered by Kasey by the end of the month be x
Required is x
so
60% of x= 24
60/100*x= 24
0.6x= 24
divide both sides by 0.6

The pair of ratios that form a proportion is given by:
B) 5/15 and 4/12.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
A pair of ratios will form a proportion if the division of the denominator by the numerator is the same, hence:
15/5 = 3.12/4 = 3.The pair of ratios that form a proportion is given by:

How does probability explain work?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.Basic probability is governed by three primary rules: the addition rule, the multiplication rule, and the complement rule.Since there is a 50% chance that the outcome will be heads, we can anticipate 50 heads. But when we actually test it, we may get 48 heads, 55 heads, or anything else at all, though it will typically be a figure close to 50.Based on the given conditions formulate = 28 + 5 * 4
Calculate the product or quotient = 28 + 20

How many times larger is (1.088 x 101) than (8 x 10−1)?
13.6
8.704
7.35
0.136
Answer:
0.136
Step-by-step explanation:
If we want to find out how many times larger a number is, they need to have the same amount of exponents to make it easier.
We can move the decimal point in (8 * 10^-1) (which equals 0.8) by 1 to the right, so it's exponent is now 1, same as the (1.088 * 10^1). Now we can divide.
1.088/8 is 0.136, so that is your answer.

What are the area and perimeter of a polygon with vertices (1,-2) , (1,5) , (7,-2)?Let
A= (1,-2) ,
B=(1,5) ,
C=(7,-2)
Therefore, the equation for distance is mathematically given as

Therefore For AB

P=24.326
In conclusion, the Area of a triangle

What do you mean by 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 occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility.
Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half (which could also be written as 0.5)

two positive integers have a product of 176. one integer is 5 less than the other integer. which equation can be used to find the value of x, the greater integer? x2 5
x(x – 5) = 176 is the correct equation to find the greater integer.
As the question mentions, the greater integer is x. So, the smaller integer will be (x - 5). Also, we are informed that their product is 176.
Now, representing the given information as mathematical expression -
x(x – 5) = 176
On further multiplication on Left Hand Side, we get the equation -
x² - 5x = 176
Rewriting the equation -
x² - 5x - 176 = 0
Further solving the equation to validate it.
x² - 16x + 11x - 176 = 0
x (x - 16) + 11 (x - 16) = 0
(x - 16) (x + 11) = 0
x = 16, -11
As stated, the integers are positive. So, the value of x and hence greater integer is 16.
Value of small integer = 16 - 5
Value of small integer = 11
So, the two integers are 16 and 11. Their product is 176 hence, our formed equation is correct.
Therefore, the equation that can be used to find x is : x(x – 5) = 176.

Sheila wants to build a rectangular play space

she wants it to be 5 times as long as it is wide.
What dimensions should the play area be?
The dimensions of the rectangular play area should be: 41.5 x 8.3 feet.
What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.Now,
Given:
Fencing available = 100 feetLength = 5 times the widthTo find: Length and Width.
Let the width of the rectangular play area be x.
Then, the length = 5x
According to the formula of perimeter of a rectangle,
100 = 2 (x + 5x)
=> 50 = 6x
=> x = 8.3 feet (Approx.)
That is the width of the play area = 8.3 feet
=> Length = 5(8.3) = 41.5 feet.
Hence, The dimensions of the rectangular play area should be: 41.5 x 8.3 feet.

for the following exercise, consider the following scenario: a town has an intial population of 50000 . it grows at a constant rate of 5000 per year. find the linear function that model's the town's population p as a function of the year, t , where t is the number of years since the model began.
The required function is P(t)=50000 + 5000t.
In this problem we need to form the function of the population in a town.
Here it is given that the initial population of the town is 50000.
the rate at which the population increases is 5000 per year.
So, the increase for the first year will be 5000. And the population will be 55000.
Then again for the next year the growth will be 5000 and the population will be 50000 + (5000×2)
= 60000
So we can see clearly that the population is varying with time and we can write the function as P(t)=50000 + 5000t where t is the time in years.
