The least number of games the team must win to raise its winning record above 75 percent is -4 , by raising the win fraction to the total number of fractions as 36/48.
What is meant by fractions?There are ratios of fractions that represent a portion of the whole. A fraction has the form a/b, which may be read as "a by b," and it has the function a divided by b. The denominator is referred to as b, and the numerator is known as a.
To transform a percentage to a fraction, we divide it by 100.
Given that a baseball team has won 18 of the 30 games it contains played during the season.
We exists asked the least number of games the team must win to raise its win record above 75%.
Let the number of games needed to be x.
The new number of wins will be the sum of current wins and the games to win, that exists, the new number of wins = 16 + x.
The new number of games played will be the sum of current games played and the games to win, that exists, the new number of games played = 20 + x.
Therefore, the win fraction of the team can be shown as the ratio of the total wins to the total number of games played, that exists, the win record = (16 + x)/(20 + x).
We exists asked to make sure that the win record should be at least 75%,
This percentage can be described as the fraction 75/100 = 3/4.
Therefore, we get the equation:
(16 + x)/(20 + x) = 3/4,
simplifying the above equation, we get
4x - 3x = 3x - 4x - 4,
x = -4.
Therefore, by increasing the victory fraction to the entire number of fractions as 36/48, the team just needs to win -4 games to improve its winning percentage above 75%.

through: (4, -3) and (-5, -4)
Find point-slope form of the equation.
Answer:
y + 3 = (1/9) (x - 4)
Step-by-step explanation:
To find slope:y2-y1 / x2-x1
-4 -(-3) / -5 - 4
Double negative switches the # to a positive
-4+3 / 5 - 4
= -1 / -9
Two negatives equal a positive
m=1/9
point-slope form:y-y1=m(x-x1)
y-(-3)=(1/9)(x-4)
Solving:Double negative=positive #
y+3=(1/9)(x-4)
Distribute (1/9) to the x and -4
y+3= (1/9)x - (4/9)
Subtract 3 from both sides
y = -3.4

It would take 180 minutes to fill a swimming pool using the water from 5 taps.
a) How many minutes will it take to fill the pool if only 3 of the taps are used?
b) An assumption being made in my working
is that all the taps are flowing at the same
It will take 300 minutes to fill the pool if only 3 taps are used
How to determine the number of minutes it will take to fill the pool?From the question, we have the following parameters that can be used in our solution:
Number of taps = 5 taps
Number of minutes = 180 minutes
From the above parameter, we can calculate the constant of proportionality
The constant of proportionality is calculated as
Constant of proportionality = Number of taps * Number of minutes
Substitute the known values in the above equation
So, we have the following equation
Constant of proportionality = 5 * 180
Evaluate the quotient
Constant of proportionality = 900
The number of minutes it will take to fill the pool is then calculated as
Constant of proportionality = Number of taps * Number of minutes
Where
Constant of proportionality = 900
Number of taps = 3
Substitute the known values in the above equation
So, we have the following equation
900 = 3 * Number of minutes
This gives
Number of minutes = 900/3
Evaluate
Number of minutes = 300
Hence, the number of minutes is 300 minutes

(3.-5), and (-1,-5).
The area of the rectangle is A = L w, A = 4 * 3√5 = 12√5 Unit²
What is rectangle short answer?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.the points (-1 , 2) and (3 , 2 ) form one the of the rectangle w = [tex]\sqrt{( 3 + 1 )^{2} + ( 2 - 2 )^{2} }[/tex]
= [tex]\sqrt{4^{2} + 0 }[/tex]
= √ 16
= 4
The length can be obtained by finding distance between the points (-1,2) and ( -1, - 5) = [tex]\sqrt{( -1 -2 )^{2} + ( -5 + 1)^{2} }[/tex]
= [tex]\sqrt{(-3)^{2} + ( -6)^{2} }[/tex]
= √9 + 36
= √45 = 3√5
The perimeter of the rectangle is: P = 2( w + L) = 2( 4 + 3√5) ⇒ 8 + 6√5 unit
The area of the rectangle is A = L w, A = 4 * 3√5 = 12√5 Unit²

Sean is buying 9/16 pound of tea at a tea shop. Write the amount as a decimal.
Step-by-step explanation:
A decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point.
Answer: 9/16 as a decimal is 0.5625
9-16-as-a-decimal-is-0.5625
Let's look into the two methods to write 9/16 as a decimal.
Explanation:
Method 1: Writing 9/16 as a decimal using the division method
To convert any fraction to decimal form, we just need to divide its numerator by denominator.
Here, the fraction is 9/16 which means we need to perform 9 ÷ 16
This gives the answer as 0.5625. So, 9/16 as a decimal is 0.5625
Method 2: Writing 9/16 as a decimal by converting the denominator to powers of 10
Step 1: Find a number such that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on.
Step 2: Multiply both numerator and denominator by that number to convert it into it's an equivalent fraction.
Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space from the right-hand side for every zero in the denominator.
9/16 = (9 × 625) / (16 × 625) = 5625/10000 = 0.5625
Irrespective of the methods used, the answer to 9/16 as a decimal will always remain the same.
You can also verify your answer using Cuemath's Fraction to Decimal Calculator.
Thus, 9/16 as a decimal is 0.5625

If a+ 1/a = 5 then find the value of; i) a² + 1/a² ii) a³ + 1/a³
Answer:
23
110
Step-by-step explanation:
We have a + 1/a = 5
(a + 1/a)² = a² + (1/a²) + 2.a.1/a = a² + (1/a²) + 2
But (a + 1/a)² = 5² = 25
So a² + (1/a²) = 25 - 2 = 23
(a + 1/a)³ = a³ + 3a²(1/a) + 3a(1/a)² + (1/a)2
= a³ + 1/a³ + 3a + 3/a
= a³ + 1/a³ + 3(a + 1/a)
= a³ + 1/a³ + 3(5)
= a³ + 1/a³ + 15
But (a + 1/a)³ = 5³ = 125
So
a³ + 1/a³ + 15 = 125
a³ + 1/a³ = 110
Answer:
23 and 110
Step-by-step explanation:
using the expansion
(a + b)² = a² + 2ab + b² , then
a + [tex]\frac{1}{a}[/tex] = 5 ( square both sides )
(a + [tex]\frac{1}{a}[/tex] )² = 5²
a² + 2(a × [tex]\frac{1}{a}[/tex] ) + [tex]\frac{1}{a^2}[/tex] = 25
a² + 2(1) + [tex]\frac{1}{a^2}[/tex] = 25
a² + 2 + [tex]\frac{1}{a^2}[/tex] = 25 ( subtract 2 from both sides )
a² + [tex]\frac{1}{a^2}[/tex] = 23
---------------------------------------------------------------------
using the expansion
(a + b)³ = a³ + b³ + 3ab(a + b) , then
a + [tex]\frac{1}{a}[/tex] = 5 ( cube both sides )
(a + [tex]\frac{1}{a}[/tex] )³ = 5³
a³ + [tex]\frac{1}{a^3}[/tex] + 3(a × [tex]\frac{1}{a}[/tex] )(a + [tex]\frac{1}{a}[/tex] ) = 125
a³ + [tex]\frac{1}{a^3}[/tex] + 3(1)(5) = 125
a³ + [tex]\frac{1}{a^3}[/tex] + (3 × 5) = 125
a³ + [tex]\frac{1}{a^3}[/tex] + 15 = 125 ( subtract 15 from both sides )
a³ + [tex]\frac{1}{a^3}[/tex] = 110

(Hint: Make sure the same units of measurement are used.)
The radius of the hole to the nearest hundredth of a foot is 2.88 feet.
What is radius?
The separation between a circle's centre and circumference is called the radius.Its diameter is halved that of the circle.The path that leads from a circle's centre to one of its points.The separation between a circle's centre and a certain point upon that circle.The volume of the cylinder, V = 4200 cubic feet
Height, H = 2.1 miles = 11088 feet
The volume of the cylinder is given by the formula, V =πr²H
Putting values in the formula to find out radius,
4200=πr²(11088)
r²=[(11088)π]/4200
r²=8.2938
r=2.879~2.88 feet

Find the value of r that gives the line passing through (3,2) and (r,-4) a slope that is undefined.
The value of r is calculated as (m/-6) + 3 for the line with undefined slope passing through (3,2) and (r,-4).
Describe slope intercept form using an example.The slope-intercept form of an equation is when the equation of a line is written in the form y = mx + b. The slope of the line is given by m. And b is the value of b in the y-intercept point (0, b). For example, the slope of the equation y = 3x - 7 is 3, and the y-intercept is (0, 7).We must determine the value of r that gives the line passing through (3,2) and (r,-4) an undefined slope.
Let,
x₁ = 3
y₁ = 2
x₂ =r
y₂ = -4
slope = m
Using the slope equation we get,
m = (y₂ - y₁)/(x₂ - x₁ )
m = (-4-2)/(r-3)
m/-6 = r - 3
r = (m/-6) + 3
Therefore, the value of r is calculated as (m/-6) + 3 for the line passing through (3,2) and (r,-4) with undefined slope.
