Step-by-step explanation:
Nicholas has a map that shows a rectangular park with a circular pond. The scale of the map is 1.5 in: 8 yd. On a map, the width of the park is 2.5 inches and the length is 6.25 inches. The pond has a diameter of 2 inches. Find the actual area of the circular pond.Use the pi key. (Answer to the nearest tenth.)
Answers
Answer:
The actual area of the pond is 88.9 yd^2
Step-by-step explanation:
We know that in the map, 1.5 inches are equivalent to 8 yards in the real park.
We know that in the map, the pond has a diameter of 2 inches.
Now we want to find the actual area of the circular pond.
Then the first step is to find the diameter of the real pond.
We know that:
1.5 in = 8 yd.
Now we need to count how many times we have 1.5 inches in the diameter of the pond in the map, this is:
N = 2 in/ 1.5in = 1.33
Then the actual diameter of the pond is 1.33 times 8 yards, this is:
D = 1.33*8yd = 10.64 yd
Now, we know that for a circle of diameter d, the area is:
A = pi*(d/2)^2
where pi = 3.14
Then the area of the pond is:
A = 3.14*(10.64 yd/2)^2 = 88.9 yd^2

Mr. Claw received a job with an annual salary of $51,000. He will receive a 1.5% increase every year. How much will Mr. Claw's salary be in 3 years?
Answers
Answer: $53,330
Step-by-step explanation:
This is an exponential function so to find the salary in 3 years, you need to use a future value formula such as :
= Amount * ( 1 + rate) ^ number of years
Amount = $51,000
Rate = 1.5%
Number of years = 3 years
Salary = 51,000 * ( 1 + 1.5%)³
= 53,329.59
= $53,330

149.49 - 44.847 = 104.643

Is x=2 a solution to 3x+5>10? Explain
Answers
To figure out if x = 2 is a solution, plug 2 in for x. If the left side is greater than 10, then x is a valid solution. If the left side is not greater than 10, than x is not a valid solution.
3x+5>10
3(2)+5>10
6+5>10
11>10
11 is actually greater than 10, so x=2 is a solution to this inequality

An airplane is flying diagonally across the state of Colorado. This state and its
dimensions are represented by the rectangle on the map shown.
Based on the measurements shown in the map, which measurement is closest to the
distance in miles the airplane will fly along the diagonal?
Answers
Answer:
C
Step-by-step explanation:
The measurement is closest to the distance in miles the airplane will fly along the diagonal is given by D = 476.1 miles
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let the dimensions are represented by the rectangle be 280 mi x 385 mi
So , the length of the rectangular path L = 280 miles
The width of the rectangular path W = 385 miles
And , the distance in miles of airplane along the diagonal is given by
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
On simplifying , we get
The distance along the diagonal D = √ ( 280 )² + ( 385 )²
The distance along the diagonal D = √ ( 78400 + 148225 )
The distance along the diagonal D = √ ( 226625 )
The distance along the diagonal D = 476.1 miles
Hence , the distance is D = 476.1 miles

The solution to the functions are when x = 1 , f ( x ) = g ( x ) = 5
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
f ( x ) = 4x + 1
And , g ( x ) = ( 3 )ˣ⁺¹ - 4
On simplifying , we get
The table of values are given and when x = 1
The value of f ( x ) = g ( x ) = 5

A fraction is a way to describe a part of a whole. The time it was taken by Ralph to mow the lawn by himself is 12 hours.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that Tom can mow a large estate's lawn in 6 hours. Therefore, the area of lawn that Tom can mow in 4 hours can be written as,
[tex]\text{Area of lawn mowed by Tom} = \dfrac46[/tex]
Now, the area of the lawn that is mowed by Ralph can be written as,
[tex]\text{Area of lawn mowed by Ralph} = \dfrac26[/tex]
Since it took 4 hours to mow 2/6 of the lawn by Ralph, therefore, the total time taken by Ralph to lawn the complete area will be thrice 4 hours.
Hence, the time it was taken by Ralph to mow the lawn by himself is 12 hours.
