Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.

39 is 5% of what number?
Answer:
780
Step-by-step explanation:
Explanation:
To get from
5% to 100% you multiply by 20, so multiply the number in this case 39 by 20 percent.
39 is 5 percent of 780.
Given that we need to find 39 is 5% of what number,
To find the number that 39 is 5% of, we can use the concept of proportions.
Let's assume the number we're looking for is represented by "x." We can set up the proportion:
39 is 5% of x
Mathematically, this can be written as:
39 = 0.05x
To solve for x, we divide both sides of the equation by 0.05:
39 / 0.05 = x
The result is:
x = 780
Therefore, 39 is 5% of 780.

A helicopter is hovering over a landing pad 100 m from where you are standing. The helicopter's
angle of elevation with the ground is 15°. What is the altitude of the helicopter? (Round answer to 2
decimal places)
Answer:
26.79 meters
Step-by-step explanation:
tan15 = x/100
x = 100tan15 ≈ 26.79
Answer is 26.79m
Angle of elevation and tan Formula:
The angle of elevation is the angle between the horizontal line of sight and the object.
The tan angle = the length of the opposite side / the length of the adjacent side.
Here, the angle of elevation is 15 degrees.
Let's altitude of the helicopter is h.
The horizontal distance is 100m
tan(15°) = h / 100
0.2679 = h / 100
=> h = 0.2679 * 100
=> h = 26.79m

what is 0.5p=p+5?
the homework said move p to the other side but i dont really understand that
Answer: p=-10
Step-by-step explanation:
0.5p=p+5
-p -p
-0.5p=5
Multiply by -0.5 on each side
p=-10
The value of p in 0.5p=p+5 is -10.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
0.5p=p+5
Now, solving for p
For which p from Right side should be moved to left side
0.5p - p= 5
-0.5p = 5
Now, Divide both side by (-0.5)
-0.5p/ (-0.5)= 5/(-0.5)
p = -10
Hence, the value of p is -10.

looking at only the tenths they round down to 25.
The numbers that would round off to 25 when rounded to the nearest whole number are 25.09 and 24.49.
What are the numbers that would round off to 25?When one is to round off to the nearest whole number, the numbers after the decimal point are to be eliminated.
To round off to the nearest whole number, if the tenth figure is equal to 5 or greater than 5, 1 would be added to the unit term, if this is not the case, zero would be added to the unit term.
When 25.09 and 24.49 are rounded off to the nearest whole number, it becomes 25

Answer:
a:b:c = 6:15:20
Step-by-step explanation:
Given;
[tex]\frac{a}{b} = \frac{2}{5} \ \ and \ \ \frac{b}{c} = \frac{3}{4}[/tex]
a:b:c is determined as follows;
a:b = 2:5 and b:c = 3:4
find the common factors in both equation = b = 5 and 3
Then, multiply the first equation by 3 and second equation by 5, so that value of b in both equations will be the same.
a:b = 6:15
b:c = 15:20
Thus, a:b:c = 6:15:20

Find the value of y. Be sure to keep the exact value (use square root and don’t round your answer).
Answer:
y = 8·√3
Step-by-step explanation:
From the drawing of the right triangle, we have;
The length of the opposite leg to the given 60° (reference) angle = 12
The length of the adjacent leg to given 60° (reference) angle = x
The length of the hypotenuse side = y
By trigonometric ratios, we have;
[tex]sin(Reference \, Angle) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
Therefore, we have;
[tex]sin(60^\circ) = \dfrac{12}{y}[/tex]
From the value of sin(60°), we have;
[tex]sin(60^\circ) = \dfrac{\sqrt{3} }{2}[/tex]
[tex]\therefore y= \dfrac{12}{sin(60^\circ) } = \dfrac{12}{\dfrac{\sqrt{3} }{2} } = \dfrac{2 \times 12 \times \sqrt{3} }{{{3} } } = \dfrac{24 \times \sqrt{3} }{{{3} } } = 8 \cdot \sqrt{3}[/tex]
y = 8·√3
[tex]\left(x= \dfrac{12}{tan(60^\circ) } = \dfrac{12}{{\sqrt{3} } } = 4\cdot \sqrt{3} \right)[/tex]

What is hypotenuse?"It is the longest side of the right triangle."
What is Pythagoras theorem?"For a right triangle, [tex]x^{2}+ y^{2}=z^{2}[/tex], where z is the hypotenuse and x, y are other two sides of the right triangle."
What is csc of angle?"In a right triangle, csc of angle is the ratio of the hypotenuse to the opposite side of angle."
For given question,
First we find the hypotenuse of the right triangle.
Using Pythagoras theorem,
[tex]\Rightarrow 9^{2} + 12^{2}= r^{2}\\\\ \Rightarrow 81 + 144=r^2\\\\\Rightarrow r=\sqrt{225}\\\\ \Rightarrow r=15[/tex]
so, the hypotenuse is r = 15
Now we find the csc of angle [tex]\theta[/tex]
[tex]\Rightarrow csc(\theta)=\frac{hypotenuse}{opposite~side~of~\theta} \\\\\Rightarrow csc(\theta)=\frac{15}{12}[/tex]
Therefore, the value of [tex]csc(\theta)[/tex] is [tex]\frac{15}{12}[/tex]

Let us assume his son be x
So, the oliver age is x + 33
Now eight years ago, oliver age is 5 more than thrice his son present age
x - 8 = 5 + 3x
So,
33 + x = 5 + 3x
2x =28
x=14
