Answer:

Step-by-step explanation:
The left side is equal to:
x/(2.52-2.02) = x/0.5 = 2x
Let's simplify the numerator of the right side.
9*(31/20 - 1.05) = 9*(0.5) = 9/2
The denominator is 43/40 - 35/8 /7 = 43/40 - 5/8 = 43/40 - 25/40 = 18/40 = 9/20.
So 2x = (9/2)/(9/20) = 10
x = 5

Devi rides the bus to her grandmother's house every day. She tracked how many minutes the bus rides took for one week: 24 32 25 24 30 30 24 calculate the mean, median, range, and mid range of the bus ride times for a week
Answer:
Mean: 27
Median: 25
Range: 8
Mid Range: 28
Step-by-step explanation:
The value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.
It is given that the time in minutes for which Devi rides the bus in a week is 24, 32, 25, 24, 30, 30, 24.
We have to find out the value of mean, median, range and mid range.
What is mean of numbers ?
The mean of numbers is the ratio of sum of all numbers to the total no. of numbers.
As per the question ;
The time in minutes for which Devi rides the bus in a week is ;
24, 32, 25, 24, 30, 30, 24.
So ;
The mean will be ;
= [tex]\frac{24 + 32 + 25 + 24 + 30 + 30 +24}{7}[/tex]
= [tex]\frac{189}{7}[/tex]
= 27
and
We know that when n is odd number then ; Median is ;
= [tex]\frac{n+1}{2}th[/tex] term
= [tex]\frac{8}{2}th[/tex] term
= 4th term
= 24
and
Range will be ;
= largest number - smallest number
= 32 - 24
= 8
and
Mid range will be ;
= (largest number + smallest number) / 2
= [tex]\frac{32 + 24}{2}[/tex]
= 56 / 2
= 28
Thus , the value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.

Step-by-step explanation:
a plane, initially traveling 150 mi/hr 100 east of north, suddenly enters a region where the wind is blowing at 50 mi/hr from the southwest. What is the plane's resultant direction?
Answer:
Velocity of plane is 100 mi/hr along northeast direction
Step-by-step explanation:
From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction
since the velocity of wind and plane is exactly opposite
⇒ relative velocity of plane with respect to wind is given by
[tex]v_r_e_l = v_p - v_w[/tex] where [tex]v_p[/tex] is the velocity of plane = 150mi/hr and [tex]v_w[/tex] = velocity of wind = 50 mi/hr
Therefore, [tex]v_r_e_l = v_p - v_w[/tex] = [tex]v_r_e_l = 150 - 50 = 100 mi/hr[/tex] alond northwest direction
Therefore, velocity of plane is 100 mi/hr along northeast direction
By working with the velocity vectors, we will find that the direction of motion of the plane is 28.7 south of east.
Working with the velocity vectors:
First, we need to define our coordinate axis, I will define the x-axis as the east and the y-axis as the north.
We know that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.
Then the x-component of the velocity is: 150mi/hr*cos(-10°) = 147.7 mi/hrThe y-component of the velocity is: 150mi/hr*sin(-10°) = -26 mi/hr.
So the vector is:
V = < 147.7 mi/hr, -26 mi/hr >
Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°, so the components of the vector are:
x-component: 50mi/hr*cos(225°) = -35.4 mi/hry-component: 50mi/hr*sin(225°) = -35.4 mi/hr.So the vector is:
W = < -35.4 mi/hr, -35.4 mi/hr>
The sum of the vectors gives the total velocity of the plane in the wind, we will get:
V + W = < 147.7 mi/hr -35.4 mi/hr , -26 mi/hr -35.4 mi/hr >
V + W = <112.3 mi/hr, -61.4 mi/hr>
The direction of a vector <x, y> is given by:
θ = Atan(y/x)
Then in this case the direction of the plane is:
θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°
So the direction of the plane is 28.7° south of east.

hour of class. After attending 33 hours of class, how many total pages of notes will Perry
have in his notebook?
Answer:
41 pages of notes
Step-by-step explanation:
Since he took 1 page of notes for each hour, and attended 33 hours of class, this will add 33 pages of notes to his notebook.
To find the total, add 8 to this, because he already had 8 pages on his own.
33 + 8
= 41
So, he will have 41 pages of notes in his notebook
Answer:

birdhouse and the pole?
.a. 12
c. 18.75
b. 15
d. 13.25
Answer:
12
Step-by-step explanation:
15 feet total amount combined by pole and birdhouse
4 foot tall person makes 5 feet long shadow
5x3=15
4x3=12 so the birdhouse and pole are 12 feet
The birdhouse and the pole are 18.75 ft tall.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have a person standing nearby who casts a shadow 5 feet long. The person is 4 feet tall.
Assume that for the birdhouse and the pole are [x] ft tall.
Now, for a 4 feet tall person, the shadow is 5 feet long.
Then, for one feet long person, the shadow would be (5/4) feet long.
Then, for 15 feet long -
x/15 = 5/4
x = (15 x 5)/4
x = 75/4
x = 18.75 feet tall
Therefore, the birdhouse and the pole are 18.75 ft tall.

Question is on the photo below
Answer:
The value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
Step-by-step explanation:
Given
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
To determine
f(x) - g(x)
Using the formula
f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)
= 3x² + x - 3 - x² + 5x - 1
= 2x² + 6x - 4
Therefore, the value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4

plug in the values,(y-1)/(3-1)=(x-4)/(3-4)
(y-1)/2=(x-4)/-1
-1*(y-1)=(x-4)*2
