The distance cover by Noah in 1 hour to cover distance is 6.5 miles
Step-by-step explanation:
Given as :
The distance cover by Lin = 2 miles = miles
The time taken to cover distance by Lin = hours
Again
The distance cover by Noah = 8 miles = miles
The time taken to cover distance by Noah = hours
Let the distance cover by Noah in 1 hour = d miles
∵ The distance cover by Noah in hours = miles
∴ The distance cover by Noah in 1 hour =
I.e d = miles
or, d = = 6.5 miles
So, The distance cover by Noah in 1 hour = d = 6.5 miles
Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer

The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fahrenheit (°F). Use the given expression to determine the temperature in degrees Celsius when F = 86°
Answer:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Step-by-step explanation:
Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:
[tex]T_{C} = \frac{5}{9}\cdot (T_{F}-32)[/tex] (1)
Where:
[tex]T_{F}[/tex] - Temperature, measured in degrees Fahrenheit.
[tex]T_{C}[/tex] - Temperature, measured in degrees Celsius.
If we know that [tex]T_{F} = 86\,^{\circ}F[/tex], then its equivalent temperature on Celsius scale is:
[tex]T_{C} = \frac{5}{9}\cdot (86-32)[/tex]
[tex]T_{C} = 30\,^{\circ}C[/tex]
The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:
To figure out the answer we have to separate it two parts
So the surface area of the piñata is
=The surface area of first cone + the area of the second second cone
=π×r×(r+s)+π×r×(r+s)
=3.14×7×(7+24)+3.14×7×(7+17)
=3.14×7×31+3.14×7×24

There are 40 dimes and quarters in a drawer. The total amount of the coins
are $4.75. How many quarters are there?
A. 35
B. 5
C. 19
Answer:
There should be 3 quarters
Step-by-step explanation:
here's why....40 dimes is 4.00 plus 3 quarters is 4.75
The required number of quarters is given as 5, as of the given conditions.
Given that,
There are 40 dimes and quarters in a drawer. The total amount of the coins is $4.75.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
let the number of dimes be d and the number of quarters be q,
According to the question,
d + q = 40 - - - - - (1)
0.10d + 0.25q = 4.75 - - - - - (2)
From equation 1 substitute x in equation 2
0.10[40 - q] + 0.25q = 4.75
4 - 0.10q + 0.25q = 4.75
0.15q = 0.75
q = 5
Out q in the equaiton 1,
d + 5 = 40
d = 35
Thus, the required number of quarters is given as 5, as of the given conditions.

The width of a rectangle is two-thirds of the length. The perimeter of the rectangle is 15 centimeters. What is the length, l, of the rectangle? Explain.
Answer:
The legth of I is 15.
Step-by-step explanation:
hope this helps :))
The length of the rectangle is given by the equation L = 4.5 cm
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the perimeter of the rectangle be represented as P = 15 cm
Now , the equation will be
Let the length of the rectangle be L
Let the width of the rectangle be W
Now , width of a rectangle is two-thirds of the length
Substituting the values in the equation , we get
W = ( 2/3 ) L
And , Perimeter P of rectangle = 2 ( Length + Width )
Substituting the values in the equation , we get
15 = 2 ( L + ( 2/3 ) L )
On simplifying the equation , we get
15/2 = L + ( 2/3 )L
15/2 = 5L/3
15 = 10L/3
Multiply by 3 on both sides of the equation , we get
45 = 10L
Divide by 10 on both sides of the equation , we get
L = 4.5 cm
Therefore , the value of L is 4.5 cm
Hence , the length of the rectangle is 4.5 cm

The player began counting at 000 seconds, even though the video had already played 190190190 frames. The video plays 252525 frames per second. How many frames had the video already played when the time was equal to -3\dfrac{2}{5}−3 5 2 minus, 3, start fraction, 2, divided by, 5, end fraction seconds?
Answer:
105 frames
Step-by-step explanation:
Given that:
At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.
When the time is equal to [tex]3 \dfrac{2}{5}[/tex], the number of frames that are already being played is:
[tex]= 3 \dfrac{2}{5} \times 25[/tex]
[tex]= \dfrac{17}{5} \times 25[/tex]
= 17 × 5
= 85 frames.
But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to [tex]3 \dfrac{2}{5}[/tex] is;
=(190 - 85) frames

The price of an item has risen to $207 today. Yesterday it was $180. Find the percentage increase
Answer:
15% '
Step-by-step explanation:
Price yesterday = $180
Price today = $207
Increase in price = $(207 - 180)
=> $27
Percent increase =
Increase / Price of yesterday
=> 27 / 180 * 100
=> 3 / 2 * 10
=> 30 / 2
=> 15
15%
Therefore, the rise in the price of the item = 15%

Andrea does not understand why if x is a solution to the equation 3-x=4 then x is also a solution to the equation 12=9-3x. Write a convincing explanation as to why this is true
Answer:
Both equations are same
Step-by-step explanation:
The reason why this is true is not far fetched
looking at the first equation, we have;
3-x = 4
we can also factorize the second equation to look this way
By this, we shall be having
3(4) = 3(3-x)
By the time we take out the 3 from both sides, we will have the initial equation
So what we are saying is that both equations are the same

Are all terminating and repeating decimals rational numbers? Explain.
Answer:
All terminating and repeating decimals are not rational numbers. For example, pi is a non-terminating & irrational number.
Step-by-step explanation:
The given statement "Are all terminating and repeating decimals rational numbers? Expla" is true.
Yes, all terminating and repeating decimals are rational numbers. A
rational number is defined as any number that can be expressed as a ratio of two integers, with the denominator not equal to zero.
Terminating decimals are those decimals that end after a finite number of digits.
For example, 0.75 is a terminating decimal because it ends after two digits. To show that such decimals are rational,
We can rewrite the decimal as a fraction.
0.75 can be expressed as 75/100 or simplified to 3/4.
Since both the numerator and denominator are integers, 0.75 is a rational number.
Now
Repeating decimals are those decimals that have a repeating pattern of digits after the decimal point.
For example, 0.3333... is a repeating decimal because the digit 3 repeats infinitely.
To show that repeating decimals are rational, we can use a similar approach to terminating decimals.
Take 0.3333... as an example.
We can represent this decimal as an infinite series:
0.3333... = 3/10¹ + 3/10² + 3/10³+ ...
This can be simplified using the formula for the sum of an infinite geometric series:
0.3333... = 3/10¹ + 3/10² + 3/10³+ ...
= (3/10)/( 1 - 1/10) (by sum of infinite geometric serires)
= 3/9
Since 3/9 can be simplified to 1/3, we can conclude that 0.3333... is a rational number.
Thus, all terminating and repeating decimals are rational numbers because they can be expressed as a ratio of two integers.
