A store bought a pair of shoes for $50 and sold it for $80. What percentage was the markup?
Must show work.
(Percent change = amount of change x 100 )
original amount
Correct answer get's brainliest) Just something to post
Answer: 60%
Step-by-step explanation: theres a $30 increase between the two prices. To find the percent change just take the difference of money over the original price. In this case it would be 30/50 or 60%
A line passes through the points (-4, 0) and (1, 10). What is its
equation in slope-intercept form?
Answer:
The answer is y=2x+8
Step-by-step explanation:
(-4,0)&(1,10)
m=y²-y¹/x²-x¹
m=10-0/1-(-4)
m=10÷5
m=2
y-y=m(x-x¹)
y-10=2(x-1)
y-10=2x-2
+10 +10
y=2x+8

What is the measure of angle x?
37
Enter your answer in the box
82
m3 =
Answer:
61
Step-by-step explanation:
we kno that a triangle is 180 degrees so we just add the first two angles
37 + 82 = 119
then subtract that from 180
180 - 119 = 61
so x = 61 degrees
lmk if this wrong and ill fix it

solve this and explain
Answer:
no, it's not.
Step-by-step explanation:
300- 284 = 16
284 - 236 = 48
236 - 156 = 80
156 - 44 = 112
for every one the top line goes up, the bottom line changes too, but it's not at a constant rate. it's not constant, therefore it cannot be linear.
the rate of change formula (or slope formula, they're the same thing) is :
y2- y1/ x2 -x1 and to solve it you plug in the points. x is the same a t and y is h
284-300/ 1-0
-16 /1
-16 (this is the rate of change between the first two points)
236- 284/ 2-1
-48/ 1
-48 (rate of change between the second and third points)
since the rate of change isn't constant, it's not possible for it to be a linear relationship.

Using the Pythagorean identity, sin^2C + cos^2C = 1, solve for sinC.
Answer:
[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]
Step-by-step explanation:
Given the Pythagorean Identity:
[tex]\sin^2(C)+\cos^2(C)=1\\[/tex]
We want to solve for sin(C).
First, we will subtract cos²(C) from both sides:
[tex]\sin^2(C)=1-\cos^2(C)[/tex]
Next, we will take the square root of both sides. Since we are taking an even-root, we will need to add plus/minus. Hence:
[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]

Consider the curve x²y + y2x = 6
dy
in terms of x and y
B) Write the equation for the tangent line where x = 2 and y = 1.
Answer:
Part A)
[tex]\displaystyle \frac{dy}{dx}=-\frac{2xy+y^2}{x^2+2xy}[/tex]
Part B)
[tex]\displaystyle y=-\frac{5}{8}x+\frac{9}{4}[/tex]
Step-by-step explanation:
We have the equation:
[tex]\displaystyle x^2y+y^2x=6[/tex]
Part A)
We want to find the derivative of our function, dy/dx.
So, we will take the derivative of both sides with respect to x:
[tex]\displaystyle \frac{d}{dx}\Big[x^2y+y^2x\Big]=\frac{d}{dx}\big[6\big][/tex]
The derivative of a constant is 0. We can expand the left:
[tex]\displaystyle \frac{d}{dx}\Big[x^2y\Big]+\frac{d}{dx}\Big[y^2x\Big]=0[/tex]
Differentiate using the product rule:
[tex]\displaystyle \Big(\frac{d}{dx}\big[x^2\big]y+x^2\frac{d}{dx}\big[y\big]\Big)+\Big(\frac{d}{dx}\big[y^2\big]x+y^2\frac{d}{dx}\big[x\big]\Big)=0[/tex]
Implicitly differentiate:
[tex]\displaystyle (2xy+x^2\frac{dy}{dx})+(2y\frac{dy}{dx}x+y^2)=0[/tex]
Rearrange:
[tex]\displaystyle \Big(x^2\frac{dy}{dx}+2xy\frac{dy}{dx}\Big)+(2xy+y^2)=0[/tex]
Isolate the dy/dx:
[tex]\displaystyle \frac{dy}{dx}(x^2+2xy)=-(2xy+y^2)[/tex]
Hence, our derivative is:
[tex]\displaystyle \frac{dy}{dx}=-\frac{2xy+y^2}{x^2+2xy}[/tex]
Part B)
We want to find the equation of the tangent line at (2, 1).
So, let's find the slope of the tangent line using the derivative. Substitute:
[tex]\displaystyle \frac{dy}{dx}_{(2,1)}=-\frac{2(2)(1)+(1)^2}{(2)^2+2(2)(1)}[/tex]
Evaluate:
[tex]\displaystyle \frac{dy}{dx}_{(2,1)}=-\frac{4+1}{4+4}=-\frac{5}{8}[/tex]
Then by the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Yields:
[tex]\displaystyle y-1=-\frac{5}{8}(x-2)[/tex]
Distribute:
[tex]\displaystyle y-1=-\frac{5}{8}x+\frac{5}{4}[/tex]
Hence, our equation is:
[tex]\displaystyle y=-\frac{5}{8}x+\frac{9}{4}[/tex]

find the measure of the line segment RQ
===========================================
Work Shown:
RS*QS = (TS)^2
RS*(QR+RS) = (TS)^2
27*(5x-12+27) = (45)^2
27*(5x+15) = 2025
135x+405 = 2025
135x = 2025-405
135x = 1620
x = 1620/135
x = 12
Use this to find the length of QR, which is the same as RQ
QR = 5x-12
QR = 5*12-12
QR = 60-12
QR = 48

The product of secant segment lengths to the points of intersection with the circle is the same for both secants. The tangent is a degenerate case where the two points of intersection are the same.
ST·ST = SR·SQ
SQ = ST^2/SR = 45^2/27 = 75
RQ = SQ -SR = 75 -27

As the ball moves from Point 3 to Point 4, which energy conversion is taking place?
Group of answer choices
potential to kinetic
kinetic potential
thermal to kinetic
kinetic to thermal
Answer: potential to kinetic
Step-by-step explanation:
Answer:
Kinetic Energy is defined as energy that a body possesses by virtue of being in motion.
Kinetic Energy is defined as energy that a body possesses by virtue of being in motion.As you walk down stairs, as water boils, and as the planets orbit the sun, kinetic energy is being utilized.GRAVITATIONALApple falls from tree and rolls behind the trunk.
GRAVITATIONALApple falls from tree and rolls behind the trunk.An object’s relative location to a gravitational field is the gravitational potential an object has to do work. Earth’s gravity will pull a ripe apple from the branch and convert it into gravitational kinetic energy.NUCLEARElectrons circle a nucleus at the atomic level.
NUCLEARElectrons circle a nucleus at the atomic level.The mass of an atom’s nucleus is almost entirely comprised of its protons and neutrons. The force binding them together is considered potential energy because it causes them to weigh less than the sum of their parts.ELASTICSpring animation expands and compresses.
ELASTICSpring animation expands and compresses.Elastic potential energy is present when the object, such as a spring, is in a deformed state but can return to a static state. This means the spring has elastic potential energy when it is either stretched or compressed.CHEMICALBattery animation motions towards a full charge.
CHEMICALBattery animation motions towards a full charge.Every animate and inanimate object is the result of chemical reactions. Chemicals in a battery have the potential to be converted into motion, therefore they have chemical potential energy.Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.When you (or a rock) are standing at the top of a hill, you possess more potential energy than when standing at the bottom. This is because your position relative to the Earth’s center of gravity can exert potential energy upon you to bring you closer to that center.Energy can neither be created nor destroyed, this is the conservation of energy law. However, energy can be altered from one form to another.
Energy can neither be created nor destroyed, this is the conservation of energy law. However, energy can be altered from one form to another.All forms of energy are either potential or kinetic energy. Potential refers to stored energy while kinetic is energy in motion.

Meryl needs to cut down 10.5 trees for every 555 cabins she builds.
Answer:
6.3 trees.
Step-by-step explanation:
We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.
Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.
Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.
