An election was held between two persons to select a representative to a certain
institution. All the voters who were registered cast their votes. The winner
received 7/12 of the votes and
won by a majority of 120 votes.
(i) What fraction of the total votes did the person who lost receive?
(ii) How many registered voters were there?
(iii) Find the number of votes the winner received.
9514 1404 393
Answer:
(i) 5/12
(ii) 720
(iii) 420
Step-by-step explanation:
(i) The fraction representing all votes is 12/12. If 7/12 were received by the winner, then the loser received 12/12 -7/12 = 5/12 of the total votes.
The person who lost received 5/12 of the total votes.
__
(ii) The winner won by 7/12 -5/12 = 2/12 = 1/6 of all votes. So, the total number of votes is ...
120 votes = 1/6(total votes)
total votes = 6×120 votes = 720 votes
There were 720 registered voters.
__
(iii) The winner received ...
(7/12)(720 votes) = 420 votes . . . received by the winner

factor the polynomial
4x^2 + 12 + 9
Answer:
The answer is [tex](2x+3)^2[/tex].
Step-by-step explanation:
Multiply the coefficient of the squared term and the constant. Then, find the factors that add up to 12:
[tex]4*9=36\\36:\{1*36,2*18,3*12,4*9,6*6\}\\6+6=12[/tex]
Split the middle term:
[tex]4x^2+6x+6x+9[/tex]
Factor by grouping:
[tex][4x^2+6x]+[6x+9]\\2x(2x+3)+3(2x+3)\\(2x+3)(2x+3)\\(2x+3)^2[/tex]
The area of a triangle is 36 sq cm. The triangle's height is 8 cm. What is the length of the base of the triangle?
Answer:
9 cm
Step-by-step explanation:
Given :
Area, A = 36cm²
Height, h = 8cm
Using the relation :
Area, A of triangle :
A = 1/2 * base * height
36 = 0.5 * base * 8
36 = 4 * base
base = 36 / 4
Base = 9 cm
Length of base is 9cm

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice
Note: The expression is missing. Consider the expression is [tex]8a+16c[/tex].
Given:
The expression is
[tex]8a+16c[/tex]
To find:
Factor form of the given expression by using GCF.
Solution:
We have,
[tex]8a+16c[/tex]
Factors of each term:
[tex]8a=2\times 2\times 2\times a[/tex]
[tex]16c=2\times 2\times 2\times 2\times c[/tex]
The common factors are 2, 2 and 2. So,
[tex]GCF(8a+16c)=2\times 2\times 2[/tex]
[tex]GCF(8a+16c)=8[/tex]
Taking out the greater common factor (GCF) in the given expression, we get
[tex]8a+16c=8(a+2c)[/tex]
Therefore, the required expression is [tex]8(a+2c)[/tex] and the correct option is C.
Factor polynomial by its greatest common monomial factor

Step-by-step explanation:
[tex]\sqrt{10^{2} -8^{2} }[/tex] = 6
Answer:
b = 6
Step-by-step explanation:
Pythagorean formula:
a² + b² = c²
Work:
a² + b² = c²
8² + b² = 10²
64 + b² = 100
b² = 100 - 64
b² = 36
[tex]\sqrt{b^2} =\sqrt{36}[/tex]
b = 6

A park has the shape of a trapezoid.
The shortest side of the park and its height have the same dimension.
Write numbers in the boxes to show the missing dimensions. What is the area of the park?
Hint: There are 3 parts in this question
Part 1 you need to find what is A
Part 2 you need to find what is B
Part 3 You need to calculate the area of all the figure ( find the area of the rectangle and two triangles then sum them all up)
Do not forget the unit!!
Answer:
[tex]the\: answer \: is \: {108 \: mi.}^{2} [/tex]
Step-by-step explanation:
Given hints:
a.) A park has the shape of a trapezoid.
b.) The shortest side of the park and its height have the same dimension.
In the given figure, the shortest side of the park is A. Since it is mentioned that the height and its shortest side have the same dimension, we can therefore say that the measure of A is 9 mi.
The longest side appears to be 6 miles longer that the shortest side:
[tex]b = a + 3 \: mi + 3 \: mi = a + 6 \: mi[/tex]
Therefore, B = A + 6 mi. = 9 mi. + 6 mi. = 15 mi.
Let's now determine the area of the park:
[tex]area = \frac{a + b}{2} h[/tex]
Where,
A = 9 mi.
B = 15 mi
H = 9 mi.
[tex]area = \frac{a + b}{2} h \\ \\ = \frac{9 \: mi. +15 \: mi. }{2} (9 \: mi.) \\ \\ = \frac{24 \: mi.}{2}(9 \: mi.) \\ \\ = (12 \: mi.)(9 \: mi. \\ \\ area = {108 \: mi.}^{2} [/tex]
The area of the park is 108 mi^2.
Please complete the table.

Step-by-step explanation:
5400 J of energy is supplied to 3 kg of aluminum, by how much
will the temperature rise? ( c of aluminum is 900 J/kg °C)
Answer:
20°C
Step-by-step explanation:
Quantity if heat energy supplied is expressed as;
Q = mcΔt
m is the mass = 3kg
Δt is the temperature rise
Q = 5400J
c = 900 J/kg °C
Substitute
5400 = 3(90)Δt
5400 = 270Δt
Δt = 5400/270
Δt = 20°C
Hence the temperature rise is 20°C

set whether each of the following equations represents a growth or decay
1. f(x)= 3[tex]^{x}[/tex]
2.f(x) = (0.25)[tex]x^{x}[/tex]
3.f(x)= [tex]\frac{2}{3x^{x} }[/tex]
4.f(x) =[tex]\frac{3}{2} x^{x}[/tex]
Answer:
Notice that the written functions are mostly incorrectly written, after a short online search i've found the correct ones, which are the ones i will write in this answer.
A general exponential equation can be written as:
f(x) = A*(r)^x
Where A is the initial value, r is the rate of growth, and x is our variable.
If r > 1, the function represents a growth.
if 0 < r < 1, the function represents a decay.
1) f(x) = 3^x
Here we have r = 3
This is clearly larger than 1, then this function represents a growth.
2) f(x) = (0.25)^x
Here we have r = 0.25, which is smaller than 1 and larger than zero, then this function represents a decay.
3) f(x) = (2/3)^x
here we have r = 2/3 = 0.66
This is larger than zero and smaller than 1, then this function represents a decay.
4) f(x) = (3/2)^x
Here we have r = 3/2 = 1.5
This is larger than 1, then this function represents a growth,

Jason a 4 lengths of rope. The lengths are 3 inches, 15 centimeters, 0.3 meters, and 0.5 feet. About how much rope does Jason have [1 inch = 2.5 cm]
Answer: 67.5 cm
Step-by-step explanation:
Jason has 4 lengths of ropes
first is [tex]3\ in.\approx 7.5\ cm[/tex]
second is [tex]15\ cm[/tex]
Third is [tex]0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}][/tex]
fourth is [tex]0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}][/tex]
the total length of rope is the sum of four lengths
[tex]\Rightarrow 7.5+15+30+15=67.5\ cm[/tex]
