We can write 56% as a fraction to the simplest form as [tex]\mathbf{= \dfrac{14}{25} }[/tex]
A fraction is a numeric value divided into two parts, the upper part(numerator) and the lower part(denominator) which are separated by a division line.
From the given information:
56% can be written in fraction as [tex]\mathbf{\dfrac{56}{100}}[/tex]
Now, to its simplest form means to divide the numerator and the denominator to their lowest term. By doing so, we have:
[tex]\mathbf{\dfrac{56}{100}}[/tex]
Divided by (2)
[tex]\mathbf{= \dfrac{28}{50} }[/tex]
Divided by (2)
[tex]\mathbf{= \dfrac{14}{25} }[/tex]
Therefore, we can conclude that 56% as a fraction to the simplest form is [tex]\mathbf{= \dfrac{14}{25} }[/tex] since no other number can go in both the numerator and the denominator.

what is the remainder when 599 / 9
see attached picture
answer is 66 with remainder of 5
Answer: The remainder is 5
Step-by-step explanation:
599 /9
59 / 9 = 6
6 ×9 = 54
that means remainder 5
Join the 5 beside the last 9, making it 59 again
repeat the first process again, i.e 59/9 = 6
6×9 = 54
Remaining 5
Therefore 9 can go into 599, 66times with a remainder of 5

A rectangular patio is 9 ft by 6 ft. When the length amd width are increased by the same amount, the area becomes 88 sq ft. Ginger is using the zero product property to solve the equation (6+x)(9+x)= 88. What do her solutions represent?
The solutions represent the additional length and width that need to be added to the original dimensions to achieve the desired area of 88 sq ft.
Explanation:The equation is: (6+x)(9+x) = 88. Ginger is using the zero product property to solve for x. The solutions she finds represent the value of x that, when added to both the length and width of the original patio, will result in a patio with an area of 88 sq ft.
By solving the equation, Ginger will find the possible values of x that will make the area of the new patio equal to 88 sq ft. These values represent the additional length and width that need to be added to the original dimensions to achieve the desired area.
For example, if Ginger finds that x = 2, then the new patio dimensions would be 9+2 = 11 ft by 6+2 = 8 ft, resulting in an area of 11 * 8 = 88 sq ft.

Andre owned a 1/4 acre lot. he wanted to construct a 120’ x 80’ tennis court on the lot. what approximate percentage of the lot will be left over, if any, when he has completed the construction?
Answer:
Answer is approx 12%
Step-by-step explanation:
Total land owned by Andre = [tex]\frac{1}{4}=0.25[/tex] acres
He wants to construct a 120 feet x 80 feet tennis court on the lot.
Means the area of the court will be = [tex]120\times80=9600[/tex] square feet.
9600 square feet = 0.22 acres (divide the area value by 43560 as 1 acre has 43560 sq feet)
Area left in acres = [tex]0.25-0.22=0.03[/tex] Acres
Hence, the approximate percentage left over will be = [tex]\frac{0.03}{0.25}\times100= 12[/tex]%
A cylindrical metal can is to have no lid. it is to have a volume of 8Ï in3. what height minimizes the amount of metal used?
To solve this problem let us say that,
h = height of the can
r = radius of the can
We try to minimize the amount of metal used which is the surface area (SA), and the equation for a cylinder is:
SA = 2πrh + πr^2
To get the minima, we take the derivative of this function and set it equal to 0. But first, the function is in two variables so we must eliminate one of them. We use the extra information given in the problem which is volume:
V = 8π = πr^2 h
Therefore,
h = 8/r^2
Plug this into the SA function to have it in terms of one variable only:
SA = 2πrh + πr^2
SA = 2πr(8/r^2) + πr^2
SA = 16π/r + πr^2
Taking the 1st derivative of the function:
0 = −16π r^−2 + 2πr
0 = −16π/r^2 + 2πr
16π/r^2 = 2πr
r^3 = 8
r = 2 in
By obtaining r, we calculate for h:
h = 8/r^2
h = 8/(2)^2
h = 8 / 4
h = 2 in (ANSWER)

What is trigonometric Ratios?"Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. It is with respect to any of its acute angles are known as the trigonometric ratios of that particular angle".
For the given situation,
Cos θ = 15/17
By using Pythagoras theorem,
We know Cos θ = [tex]\frac{base}{hypotenuse}[/tex]
Sine θ = [tex]\frac{perpendicular}{hypotenuse}[/tex]
tan θ = [tex]\frac{perpendicular}{base}[/tex]
By Pythagoras theorem, [tex]Hypotenuse^{2}= base^{2}+perpendicular^{2}[/tex]
⇒[tex]17^{2}=15^{2}+perpendicular^{2}[/tex]
⇒[tex]perpendicular^{2}= 289-225[/tex]
⇒[tex]perpendicular=\sqrt{64}[/tex]
⇒[tex]perpendicular=8[/tex]
Thus, Sec θ = 17/15
Tan θ = 8/15
Sine θ = 8/17
Cosec θ = 17/8.

Which lines can you conclude are parallel given that m14 + m2 = 180? Justify your conclusion with a theorem.
Answer:
Option 2 is correct.
Step-by-step explanation:
Given the diagram and also the condition m∠14 + m∠2 = 180°
we have to tell which lines are parallel.
By the theorem of exterior angles
Same-side exterior angles which are formed outside of the parallel lines and on same side of transversal line.
The theorem states that when parallel lines are cut by a transversal line, the sum of the same-side exterior angles is 180° i.e these are supplementary.
∴ Lines a and b are are parallel by converse of same side exterior angle theorem.
Δ abc is isosceles. angles b and c are congruent. the m∠a = 40°, m∠b = (3x + 1)°. find x.
a.13
b.23
c.46.3
d.70
Final answer:
In an isosceles triangle with angles B and C congruent, and with m∠A equal to 40°, the equation to find x is 40° + 2(3x + 1)° = 180°. Solving this equation yields x = 23°, which corresponds to option b.
Explanation:
Since ΔABC is an isosceles triangle and angles B and C are congruent, m∠B = m∠C. Given that m∠A = 40°, we can set up an equation to find x since the sum of all angles in a triangle equals 180°.
Equation: 40° + (3x + 1)° + (3x + 1)° = 180°
Combining like terms:
40° + 2(3x + 1)° = 180°
40° + 6x + 2° = 180°
6x + 42° = 180°
6x = 180° - 42°
6x = 138°
x = 23°
Therefore, the value of x is 23°, which corresponds to option b.

For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional. If x = 3, then x2 = 9.
Answer: The converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.→ which is not true.
We cannot form a biconditional statement for the given statement because the converse is not true.
Step-by-step explanation:
Given statement: If x = 3, then [tex]x^2=9[/tex]
The converse statement of conditional statement that "if p then q" is "if q then p".
therefore, the converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.
But the converse is not true since if [tex]x^2=9[/tex] then x can be 3 or -3 .
∵ [tex]3^2=9[/tex] and [tex](-3)^2=9[/tex]
A biconditional statement is true if and only if both the conditional statement and its converse are true.
Therefore, we cannot form a biconditional statement for the given statement because the converse is not true.
The converse of the conditional statement 'If x=3, then x²=9' is 'If x²=9, then x=3'. As both these statements are true, they can be combined into a biconditional statement 'x=3 if and only if x²=9'.
Explanation:
In your question, you asked how to write the converse of a given conditional statement and then combine them if the converse is also true. The original conditional statement is 'If x = 3, then x² = 9.' The converse of this statement would be 'If x² = 9, then x=3.' In this case, the converse is also true because if x² equals 9 then x does indeed equal 3. Therefore, we can combine the conditional statement and its converse into a biconditional statement: 'x = 3 if and only if x² = 9.'

How many ways are there to place 5 basketball players on the court if you must place 2 guards, 2 forwards and a center, from a team of 12, consisting of 4 guards, 5 forwards and 3 centers?
Final answer:
There are 180 ways to place 5 basketball players on the court, selecting 2 guards, 2 forwards, and 1 center.
Explanation:
To determine the number of ways to place 5 basketball players on the court, we need to find the number of combinations of guards, forwards, and centers that can be selected from the available players. There are 4 guards, 5 forwards, and 3 centers in the team.
The number of ways to select 2 guards from 4 is C(4,2) = 6.
The number of ways to select 2 forwards from 5 is C(5,2) = 10.
The number of ways to select 1 center from 3 is C(3,1) = 3.
By the multiplication principle, the total number of ways to place the players on the court is 6 × 10 × 3 = 180.
