Answer:
90 males.
Step-by-step explanation:
To find the answer we will divide 45% by 100, and we get 0.45. Now multiply 0.45 by 200 and you get 90. Therefore, 90 males is the answer.

The price of televisions has dropped dramatically over the last three years. Three years ago a 32 inch television was $500. This year the tv was on sale for $199. What is the percent change?
A percentage is a way to describe a part of a whole. The percentage change in the price of the TV will be 60.2%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is mentioned that the price of the tv 3 years ago was $500, while the current price of the tv is $199. Therefore, the percentage change in the price of the tv can be written as,
[tex]\rm Percentage\ change = \dfrac{\text{Initial value - Final value}}{Initial\ value} \times 100\%[/tex]
[tex]\rm Percentage\ change = \dfrac{\$500-\$199}{\$500} \times 100= 60.2\%[/tex]
Hence, the percentage change in the price of the TV will be 60.2%.

Write a quadratic polynomial, sum and product of whose
zeroes are -4 and -21 respectively.
Answer:
x^2 -4x -21
Step-by-step explanation:
Here, we want to write a quadratic polynomial
We have the sum as -4
Let us have x as the variable
so the sum of the variables is -4x
while the product is -21 x^2
Two factors of 21 that can work here is -7x and 3x
So we have
x^2 - 7x + 3x -21
= x^2 -4x -21
Expand and simplify (x − 3)(2x + 3)(4x + 5)
Answer:
8x³ - 2x² - 51x - 45
Step-by-step explanation:
Given
(x - 3)(2x + 3)(4x + 5) ← expand second/third factors using FOIL
= (x - 3)(8x² + 22x + 15) ← distribute
= x(8x² + 22x + 15) - 3(8x² + 22x + 15) ← distribute parenthesis
= 8x³ + 22x² + 15x - 24x² - 66x - 45 ← collect like terms
= 8x³ - 2x² - 51x - 45
Answer:
8x^3-2x^2-51x-45
Step-by-step explanation:
(x − 3)(2x + 3)(4x + 5)
(2x^2+3x-6x-9)*(4x+5)
(2x^2-3x-9)*(4x+5)
= 8x^3-2x^2-51x-45

Find the solution of the system of equations.
4x – 8y = -44
2x + 4y = -6
Answer:
x= -7/2
y= 5/4
Step-by-step explanation:
x-2y=-11
x+2y = -6
then isolate x and set equal to each other
-2y - 6 = 2y -11
4y = 5
y = 5/4
then solve for x using y.
x+5/2 = -6
x = -7/2

from the point p(-2,4) if PQ is drawn perpendicular to line 7x-24y+10=0,find the eqaution of the lin PQ . also determine the length of PQ
Answer:
7y+24x = -12
Step-by-step explanation:
Equation of line PQ in point slope form is expressed as;
y -y0 = m(x-x0)
m is the slope of {Q
(x0, y0) is the point on the line
Given the line 7x-24y+10=0
Get the slope
-24y = -7x -10
y = -7/-24 x - 10/-24
y = 7/24 x + 5/12
Slope = 7/24
Slope of the line PQ perpendicular to it = -24/7
Substitute m = -24/7 and (-2, 4) into the formula;
y - 4 = -24/7(x+2)
7(y-4) = -24(x+2)
7y - 28 = -24x-48
7y + 24x = -40 + 28
7y+24x = -12
This gives the equation of the line PQ

Being proportional means that if you divide the Y value by the X number for each ordered pair, they all equal the same number
For this case, this is proportional because you need to multiply by 6 to get the Y value.
a[tex]a^{2}+12^{2} = 13^{2}[/tex]
Answer:
a = ± 5
Step-by-step explanation:
Given
a² + 12² = 13² , that is
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a = ± [tex]\sqrt{25}[/tex] = ± 5

5 x -4 = x
-20 = x
x= -20
CHECK
(-20/-4)-10 = -5
5 -10 = -5
