Answer:
18.35
Step-by-step explanation:
This is a question which requires you to work backwards.
Divide means multiply and vice versa
Addition means subtract and vice versa
First, we find the number before 47.7.
47.7-11=36.7
Secondly, we find the number before 36.7, aka the original number.
36.7/2=18.35 (/ sign means divide)

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. 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.
Answer:
A
Step-by-step explanation:
There is no dialation of the figure. Simply a rigidmotion. There is no need to change the shape, merely the sign befre the number.
Which of the following does not always maintain a shape's congruency?
A) Translation
B) Reflection
C) Dilation
D) Rotation
Answer:
C
Step-by-step explanation:
Dialation because when a shape is made bigger it cannot be mapped back on its self correctly
Heyyy! What is 0.45 (5 repeating) as a fraction?
Answer:
41/90
Step-by-step explanation:
- The answer given above does not actually have the repeating 5, this fraction does:
x = 0.455555
100x = 45.55555
10x = 4.5555555
90x = 41 (rounded)
therefore, the fraction is 41/90

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°
The number 45 is no
more than the difference of 2 times a number m and 3.
Answer:
m ∈ <24, ∞)Step-by-step explanation:
m - given number
2m - 2 times the number m
2m-3 - the difference of 2 times the number m and 3
the number 45 is no more than the difference of 2 times a number m and 3
45 ≤ 2m - 3
-2m -2m
45 - 2m ≤ -3
-45 -45
- 2m ≤ -48

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

(Make sure to answer with a whole number.
Answer: 6.02
Step-by-step explanation:
If we know 1 gallon = 2.49
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·

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
Answer:
Step-by-step explanation:
You could do it this way.
How many hours are there in a year?
365 * 24 = 8760 hours.
This camera does not recognize days. It works on hours. Every 18 hours it resets. So
8760/18 = 486 and 2/3 times.
Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.
The answer is 486 times.
2/3 * 24 = 16
The camera would reset 2 hours into the next day.

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

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.
