Answer: y = 60x, choice D
=================================================
Explanation:
1 hour = 60 miles ... one way to represent the speed of 60 mph
x hours = 60x miles ... multiply both sides by x
After x hours, the cheetah has ran 60x miles. This is assuming the speed is kept the same at 60 mph.
The information about the 50 yards is never used. It's likely thrown in there as filler or as a distraction.

17 + (-31) = -48
Answer:
the positive 17 is the problem. so it should be: -17 + (-31) = -48
Step-by-step explanation:
if 17 is positive, the equation is just: -14 = -48 (which isnt correct)
Solve and Explain what the equation states. E=mc2 what does this state?
Answer:
Energy=Mass * the speed of light^2
Step-by-step explanation:
I'm not to sure how to explain this but I'll try my best.
Albert Einstein discovered this equation, E=mc^2.
The equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

(15 points and brainliest) If x = 0 and y < 0, where is the point (x, y) located? A. on the x axis B. on the y axis
Answer:
On the y axis
Step-by-step explanation:
If x is zero, it automatically has to be on the y axis because x=0 is where the x and y axis intersect.
A cone of radius 10 cm and height 16 cm is divided into two parts by a plane through the midpoint of its
axis parallel to its base. Find the ratio of the volumes of the two parts?
Answer:
The ratio of their volumes (the top to bottom half) is 1/7
Step-by-step explanation:
The given parameters are;
The radius, r, of the cone = 10 cm
The height of the cone = 16 cm
The point at which the cone is divided = The midpoint of the its axis and parallel to its base
The ratio of the of the volume of the two parts is given as follows;
The volume, V of the entire cone = 1/3 × Base area (π·r²) × Height, h
Therefore;
V = 1/3 × π × 10² × 16 =1600·π/3 = 1675.52 cm³
The height at which the cone is divided = 16/2 = 8 cm
The height, h₁ of the uppermost divided cone = 8 cm
The ratio of the radius to the height of the cone = 10/16 = 5/8
The radius r₁, of the uppermost divided cone = The height of the uppermost divided cone × The ratio of the radius to the height of the cone
∴ r₁ = 8 × 5/8 = 5 cm
The volume, V₁, of the uppermost divided cone = 1/3 × (π·r₁²) × h₁
∴ V₁ = 1/3 × π × 5² × 8 = 200·π/3 = 209.44 cm³
Which gives;
The volume of the lower cone, V₂ = V - V₁
V₂ = 1675.52 cm³ - 209.44 cm³ = 1400·π/3 = 1466.1 cm³
The ratio of their volumes V₁ : V₂ = V₁/V₂ = (200·π/3)/(1400·π/3) = 209.44/1466.1 = 1/7.

A boy moves down the hall at 1.2 m/s. When he sees his arch nemesis coming, he begins to run. After 3.2 s, he is moving at 4.4 m/s. What is his acceleration?
Answer:
1m/s²
Step-by-step explanation:
Acceleration is the change in velocity of a body with respect to time.
Acceleration = Change in velocity/time
Acceleration (a) = final velocity(v)-initial velocity(u)/time(t)
Given parameters:
final velocity v = 4.4m/s
initial velocity u = 1.2m/s
time taken = 3.2s
Required
Acceleration
Substitute the given parameters into the formula to get the acceleration
Acceleration = 4.4 - 1.2/3.2
Acceleration = 3.2/3.2
Acceleration = 1m/s²
Therefore the boy acceleration is 1m/s²

Solve by factoring:
5x^2 + 19x + 12 = 0
When solving polynomial equations, first set the equation
equal to zero, then check for a Greatest Common Factor.
Since there is no greatest common factor, this will make life a
little bit more difficult because we will have to factor the trinomial.
First, find all possible factors for constant term.
I have listed these in red below.
Make sure to reverse the factors since in each binomial,
the first term is different so we need to reverse the factors.
The factors of 5x² will just be 5x and z.
After finding factors for the constant and the leading
coefficient for your trinomial, we can eliminate some factors.
If you have an odd coefficient on the middle term,
you can eliminate any pairs of even factors.
So the group I crossed out in purple below will be eliminated.
Another strategy is to use factors a little closer together.
So I would go with the 4 and 3 group.
Surely enough, our trinomial does factor with the 4 and 3.
Now set the factored trinomial equal to 0.
Then use zero product property and you have your answer.
Answer:
-0.27
Step-by-step explanation:
5x^2=25x
25x+19x=44x
44x+12=0
-12=0-12
44x=-12
44x/44=-12/44
x=-0.27

9) move 5r to other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2
10) multiply both side by b/1 so b got cancel on left side
right side become c(b/1) which is same as cb

7) Tom is deciding whether or not he should become a member of the gymſto use their basketball courts. The
membership cost is $135. Members pay $2 to rent out the basketball courts. Non-members can rent the court also, but
they have to pay $11 each time. How many times would Tom need to rent the court in order for it be cheaper to be a
member than a non member?
Answer:
15 times for it to be equal, 15+ to be cheaper
Step-by-step explanation:
135+2x=11x
135=9x
135/9=x
15=x
135+2(15)=165$
11(15)=165$
Answer:
16 times
Step-by-step explanation:
Create an inequality where x represents the number of times he rents out the court:
2x + 135 < 11x
Solve for x:
135 < 9x
15 < x
So, Tom would have to rent the court out 16 times for it to be cheaper
Sherie bought a beach towel that normally costs $44 but was on sale for half price. She also bought a beach hat that was on sale for $12 off. Before tax, her total cost was $38. What was the regular price of the beach hat?
$22
$28
$48
$56
Answer:
$28
Step-by-step explanation:
The towel was $44 but at 1/2 off would be $22.
Her total cost was $38 so we subtract $22 from $38 to find how much she paid for the beach hat.
$38-$22 = $16
We add $12 to $16 to find the original price of the hat.
$16+$12 = $28
Answer:
$28
Step-by-step explanation:
6x + 2x - 9 = 7
Solve the equation and simplify the answer
Answer:
x=2
Step-by-step explanation:
6x+2x-9=7
Combine like terms on each side of the equation
8x-9=7
Add 9 to each side
8x=16
Divide by 8 on each side
x=2
Simplifying
6x + -2x + -9 = 7
Reorder the terms:
-9 + 6x + -2x = 7
Combine like terms: 6x + -2x = 4x
-9 + 4x = 7
Solving
-9 + 4x = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 4x = 7 + 9
Combine like terms: -9 + 9 = 0
0 + 4x = 7 + 9
4x = 7 + 9
Combine like terms: 7 + 9 = 16
4x = 16
Divide each side by '4'.
x = 4
Simplifying
x = 4

This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.

The gravitational potential energy, ‘G’ of an object is directly proportional to its height, ‘h’ above
the surface of Earth. When the object is at a height of 40 meters above Earth, its gravitational
potential energy is 2200 joules. Find
I. An equation connecting G and h.
II. The gravitational potential energy of the object when it is at a height of 22 meters above the
surface of Earth.
III. The height of the object above the surface of Earth when it has a gravitational potential
energy of 3025 joules.
Answer:
see explanation
Step-by-step explanation:
Given that G is directly proportional to h then the equation relating them is
G = kh ← k is the constant of proportion
To find k use the condition h = 40 when G = 2200, then
2200 = 40k ( divide both sides by 40 )
55 = k
1
G = 55h ← equation of proportion
11
When h = 22, then
G = 55 × 22 = 1210 joules
111
When G = 3025, then
3025 = 55h ( divide both sides by 55 )
h = 55 m
In a lab a 30% acid solution is being mixed with a 5% acid solution to create a 10% acid solution. What is the ratio of the amount of the 30% solution to the amount of 5% solution used to create the 10% solution
Answer:
1:4
Step-by-step explanation:
Let it be:
30% solution = x5% solution = ythen
10% solution = x + y----------
Amount of acid:
0.3x + 0.05y = 0.1(x+y)0.3x + 0.05y = 0.1x + 0.1y0.2x = 0.05y20x = 5y4x = yx/y = 1/4So the ratio of 30% solution to the 5% solution is 1:4
Answer:
1 : 4
Step-by-step explanation:
For a problem of this nature, a simple diagram makes the solution trivially easy. In the attached, the constituent concentrations are listed on the left, the solution concentration is in the middle, and the numbers on the right are the differences along the diagonals. These are the ratios of the respective solutions on the left.
