Answer:
A. 60%
B. The original price is $50
Step-by-step explanation:
A. 60%
Sales Price = 100 - 40 = 60%
The sales price is $30.00
Therefore 60% is equal to $30.00
60% = $30
1% = 30 ÷ 60 = $0.50
100% = 5 x 100 = $50
B. The original price is $50
Percentage of the original price = 30/50 x 100 = 60%

Can a triangle with side lengths of 15, 13, and 6 can be classified as a right triangle? ? and why?
Answer:
The triangle cannot be classified as right angled triangle.
Step-by-step explanation:
Given measurements are;
15, 13 and 6.
In right angle triangle, the sum of square of lengths of smaller sides is equal to square length of larger side.
Therefore,
[tex](6)^2 + (13)^2 = (15)^2\\36 + 169 = 225\\205 \neq 225[/tex]
Hence,
The triangle cannot be classified as right angled triangle.

How do I do this? I’m not really sure.
Answer:
Step-by-step explanation:
f(x) + g(x) = 3x^2 + 2x - 1 + x^2 - 3x + 1
f(x) + g(x) = 4x^2 - x
==================================
f(x) - g(x) = 3x^2 + 2x - 1 - x^2 + 3x - 1
f(x) - g(x) = 2x^2 + 5x - 2

The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake, . Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1? A. B. C. D.
Answer:
The equation is = I = [tex]e^{4.8}[/tex]
Step-by-step explanation:
As given ,
M - magnitude of an earthquake
I - intensity of earthquake
I₀ - intensity of a reference earthquake
The relation between the three is as follows :
M = log([tex]\frac{I}{I0}[/tex] )
As given -
M = 4.8, I₀ = 1
⇒ 4.8 = log([tex]\frac{I}{1}[/tex]) = log(I)
⇒ 4.8 = log(I)
⇒I = [tex]e^{4.8}[/tex]
So, the equation becomes I = [tex]e^{4.8}[/tex]

The perimeter of a rectangular garden is 78 feet. the width is six feet less than twice the length. Find the length and width of the garden.
Answer:
L=7.94 feet, W=9.88 feet
Step-by-step explanation:
perimeter=78 feet
LxW=78
2L-6=W
substitute
Lx(2L-6)=78
2L^2-6L=78
2L^2-6L-78=0
factor
(2L-15.86)(L+4.95)=0
2L=15.88, L=7.94
L=-7.94 feet

In circle F, the measure of ∠AFE is equal to 120° and the measure of arc BD is equal to 20°.
What is the measure of ∠C?
100°
40°
60°
50°
Answer:
40
Step-by-step explanation:
AFE=120 so arc AE is also 120
those 3 angles add up to 180 and 180-120-20=40
The measure of ∠C is 40°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Angle measure of central angle is equals to measure of intercepted arc.
External angle formed outside a circle,
= Half the difference of the major and minor arc =
Angle measure of AFE
= arc AE = 120°
Thus:
m∠C = 1/2(120 - 40)
m∠C = 40°
So, the angle measure of C is 40°
Therefore, 40° is the measure of ∠C.

What do the following two equations represent?
y - 2 = x + 20
y - 2 = -(x+20)
Answer: Perpendicular lines
Step-by-step explanation:
The first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.
The two equations, y - 2 = x + 20 and y - 2 = -(x + 20), represent linear equations in standard form. Let's break down each equation:
y - 2 = x + 20
This equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the value of x plus 20. This equation can be rearranged to slope-intercept form (y = mx + b) by isolating y:
y = x + 20 + 2
y = x + 22
The equation y = x + 22 represents a line with a slope of 1 and a y-intercept of 22.
y - 2 = -(x + 20)
Similarly, this equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the negative of the value of x plus 20. This equation can also be rearranged to slope-intercept form by isolating y:
y = -(x + 20) + 2
y = -x - 20 + 2
y = -x - 18
The equation y = -x - 18 represents a line with a slope of -1 and a y-intercept of -18.
In summary, the first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.

k+a=500
3k+10a=3,600
find k and a using elimination plss helppp
Answer:
a=300 and k=200
Step-by-step explanation:
Multiply the first equation by -10,and multiply the second equation by 1.
−10(a+k=500)
1(10a+3k=3600)
Becomes:
−10a−10k=−5000
10a+3k=3600
Add these equations to eliminate a:
−7k=−1400
Then solve−7k=−1400for k:
−7k=−1400 (Divide both sides by -7)
[tex]\frac{-7k}{-7} =\frac{-1400}{-7}[/tex]
Now that we've found k let's plug it back in to solve for a.
Write down an original equation:
a+k=500
Substitute200forkina+k=500:
a+200=500
a+200+−200=500+−200(Add -200 to both sides)
a=300
