John and his three brothers share a cell phone plan. The cell phone company charges a flat rate of $90 per month, which the four brothers share equally. In addition, the cell phone company charges 25 cents per megabyte of data downloaded. Each brother pays for his own downloaded data.
John's share of the current cell phone bill is $147.50.
Which equation determines how many megabytes of data John downloaded?
A. 90+0.25x = 147.50
B. 90x+0.25 = 147.50
C. 22.5+0.25x = 147.50
D. 22.5x+0.25 = 147.50
Answer:
C
Step-by-step explanation:
90/4 is 22.5 so one brother pays $22.5 of the flat fee. Because we don't know the number of megabytes John used, and one megabyte is 0.25, that would make is 0.25x.
so the equation it 22.5+0.25x = 147.50

Answer: y=9
Step-by-step explanation:
Simplifying
7y = 3y + 36
Reorder the terms:
7y = 36 + 3y
Solving
7y = 36 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
7y + -3y = 36 + 3y + -3y
Combine like terms: 7y + -3y = 4y
4y = 36 + 3y + -3y
Combine like terms: 3y + -3y = 0
4y = 36 + 0
4y = 36
Divide each side by '4'.
y = 9
Simplifying
y = 9

9

The graphic below shows quadrilateral ABCD and its dilation, quadrilateral A’B’C’D’, with the origin as the center of dilation. The scale factor is .
Which statement about both quadrilaterals is true?
Quadrilateral ABCD is congruent to quadrilateral A’B’C’D’.
The corresponding angles of quadrilaterals ABCD and A’B’C’D’ are congruent.
The corresponding sides of quadrilaterals ABCD and A’B’C’D’ are congruent.
The corresponding angles of quadrilaterals ABCD and A’B’C’D’ are not congruent.
Answer:
The corresponding angles of quadrilaterals ABCD and A’B’C’D’ are congruent.
Step-by-step explanation:
One of the rules of dilation in geometry is that dilations, no matter what point you are dilating from, will change the angle. Dilations will only ever change the length of the sides.
The graph models the linear relationship between the temperature of Earth's atmosphere and the altitude above sea level. Earth's Atmosphere Which of these best represents the rate of change of the temperature with respect to altitude? -6.5°C/km -3.5°C/km -0.29°C/km -0.15°C/km
Answer:
A. -6.5°C/km
Step-by-step explanation:
It's easier to find slope if we can locate two points.
Looking at the graph, it looks like it passes through the points (4, -10) and (7,-30).
To find the slope, we divide the difference of the y-coordinates by the difference of the x-coordinates. Here, the difference in the y-coordinates is:
-10 - (-30) = -10 + 30 = 20
The difference in the x-coordinates is:
4 - 7 = -3
So, the slope is:
20/(-3) = -20/3 ≈ -6.67
This is the closest to the first answer choice, -6.5°C/km, so that is the answer.

The decibel level of the sound of a monster truck is
Further explanation:
Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.
In the question it is given that the intensity of the sound of a monster truck is watts per square inch.
The formula which is used to calculate the decibel level of a sound is as follows:
Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .
The value of the threshold intensity of hearing at is watts per square meter.
This implies that the valiue of is watts per square meter.
The intensity of the sound of a monster is given in unit of per square inch.
The relation between per square inch and per square meter is as follows:
So, the intensity of a monster truck is converted into per square meter as follows:
This implies that the value of is watts per square meter.
Now, substitute the value of and in the equation .
The approximated value of the above equation is as follows:
