Answer: they are different because h=50 means that h and 50 are equal meaning that h is 50. H>50 means that h is not 50 but could be anything greater than 50
Step-by-step explanation:
Step-by-step explanation:
i think the difference between h=50 and h>50 is that if h=50 then h is 50 but if h>50 then h is larger than 50
A rectangular swimming pool measures 50 meters in length and 25 meters in width. What are the length and width of your scaled drawing with a scale of 1 centimeter represents 5 meters?
Answer:
10 cm by 5cm
Step-by-step explanation:
We know that for every 5 meters, there will be 1 centimeter. The pool is 50 meters by 25 meters. So to find this in terms of centimters, divide by 5 to get 10 cm by 5 cm.

Triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime negative 3 comma negative 1, B prime negative 1 comma 2, and C prime negative 3 comma negative 5.
Answer:
The correct option is;
Triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3
Step-by-step explanation:
The given parameters are;
The equation of the line t over which ΔABC is reflected is given by y = x
The coordinates of the vertices of ΔABC are given as follows;
A(-1, 1), B(1, -1), and C(-3, -1)
The reflection of a preimage (x, y) across the line y = x gives an image with coordinates at (y, x)
Therefore, the coordinates of the vertices of the image ΔA'B'C' after the reflection of the preimage ΔABC over the line, y = x are given as follows;
Coordinates of preimage → Reflection across y = x → Coordinates of image
A(-1, 1) [tex]{}[/tex] Reflection across the line y = x A'(1, -1)
B(1, -1) [tex]{}[/tex] Reflection across the line y = x B'(-1, 1)
C(-3, -1) [tex]{}[/tex] Reflection across the line y = x C'(-1, -3)
Therefore, the correct option is triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3.

The work W required to move a particle from a far distance to within radius r of another particle varies jointly as the product of the two particles' charges q1 and q2 and inversely as the radius r. Write a formula that models this proportion. (Use k as the constant of variation.)
Answer:
W = kq1q2 / r
Step-by-step explanation:
W varies jointly as the product of q1 and q2 and inversely as radius r
Product of q1 and q2 = q1q2
W = (k*q1"q2) / r
W = kq1q2 / r
Where,
W = work
q1 = particle 1
q2 = particle 2
r = radius
k = constant of proportionality
The answer is W = kq1q2 / r
Using proportions, it is found that the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]
Work varies jointly as the charges, thus, the charges are in the numerator.Inversely as the radius, thus, the radius is in the denominator.There is a constant of proportionality k, which multiplies the fraction;Then, the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]

John drove 504 miles in 8 hours. At the same rate, how many miles would he drive in 13 hours?
The distance travelled by John in 13 hours is 819 miles.
What are arithmetic operations?The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.
The total distance covered in 8 hours is 504 miles.
Then in one hour, distance covered is given as below,
⇒ Number of miles ÷ Number of hours
⇒ 504 ÷ 8 = 63
Then, the distance covered in 13 hours is given as,
⇒ Unit distance in 1 hour × Number of hours
⇒ 63 × 13 = 819
Hence, the miles travelled in 1 hour is given as 819 miles.

If using the method of completing the square to solve the quadratic equation
x2 - 6x – 34 = 0, which number would have to be added to "complete the
square"?
Answer:
9
Step-by-step explanation:
divide -6 by 2 then square the answer(-3)=9
The solution of x² - 6x – 34 = 0 by completing square method is
⇒x = 3 ±√43
The given quadratic equation is
x² - 6x – 34 = 0,
We know that whole square formula
(p+q)² = p² + q² + 2pq
Now convert the given expression into this form
So adding 9 both sides
⇒ x² - 6x – 34 + 9 = 9
⇒ x² - 6x + 9 = 43
⇒ x² - (2)(3)x + 3² = 43
⇒ (x - 3)² = 43
Taking square root both sides we get
⇒ (x - 3) = ±√43
Add 3 both sides we get
⇒ x = 3 ±√43
Thus the solution of the given quadratic equation is
x = 3 ±√43

If 3x+4y=4 and 2x+y=1, then the value of 2x+3y is equal to
Answer:
3.
Step-by-step explanation:
3x + 4y = 4..........1
2x + y = 1.............2 Multiply this by 4:
8x + 4y = 4 Subtract this from equation 1:
-5x = 0
x = 0.
So substituting in equation 2:
2(0) + y = 1
y = 1.
Therefore 2x + 3y = 2(0) + 3(1) = 3.

A screwdriver is dropped from the top of an elevator shaft. Exactly 6.0 seconds later, the sound of the screwdriver hitting bottom is heard. How deep is the shaft? Hint: The distance that a dropped object falls in t seconds is represented by the formula s = 16t2. The speed of sound is 1100 ft/sec. The shaft is approximately (Round to the nearest tenth.) | feet deep.
Answer:
Step-by-step explanation:
Using the equation of motion
S = ut+1/2gt²
S is the height of fall
g is the acceleration due to gravity = 9.81m/s²
u is the initial velocity = 0m/s
t is the time = 6s
Substitute in the formula;
S = 0+1/2(9.81)×6²
S = 4.905×36
S = 176.58m
The shaft is 176.58m deep
Given the expression for distance
S = 16t²
Velocity V = dS/dt
V = 32t
Given v = 1100
1100 = 32t
t = 1100/32
t = 34.375secs
Substitute t = 34.375 into S = 16t²
S = 16(34.375)²
S = 18,906.25ft

Answer:
the measure of angle 4 is 52 degrees.
Step-by-step explanation:
The measure of angles 3 and 4 added together is 90 degrees. Angle 3 is 38 degrees. 90-38=54.
Answer:
∠ 4 = 52°
Step-by-step explanation:
The 3 angles lie on a straight line and sum to 180°, that is
90 + ∠ 3 + ∠ 4 = 180, substitute ∠ 3
90° + 38° + ∠ 4 = 180°
128° + ∠ 4 = 180° ( subtract 128° from both sides )
∠ 4 = 52°

We would have to do 15.00 divided by 2.49 in order to figure out how many gallons we need. When we do that we would get 6.024 but you can round by the nearest tenth because you need to have a whole number and you would get 6 ·ω·
