Answer:
198 students walk to the local high school
Step-by-step explanation:
Total number students = 825
1/5 of the students travel by car
48% of the students travel by bus
0.08 of the students travel by bicycle
To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students
Students who travel by car = 1/5×825
= 165 students
Students who travel by bus = 48% × 825
= 48/100 × 825
= 12/25 × 825
= 396 students
Students who travel by bicycle = 0.08 × 825
= 66
So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school
Students that walk to school = 825 - (165 + 396 + 66)
= 825 - 627
= 198 students
Therefore 198 students walk to the local high-school
2x-1+3x=0 5x-1=0 how can we get equation b from a
Rewrite one side (or both) by combining like terms.
What is equation?It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
2x – 1 + 3x = 0..........(A)
5x – 1 = 0................(B)
To get Equation B from A, we would rewrite one side (or both) by combining like terms
2x – 1 + 3x = 0
5x – 1 = 0

I If the game with 3 hits is considered to be recorded in error, it might be removed from the data set. If that happens a. What happens to the mean of the data set? b. What happens to the median of the data set? plot data- 2(0) 3(1) 4(0) 5(0) 6(0) 7(2) 8(4) 9(5) 10(4) 11(4) 12(0) 13(0) .please help
Answer:
If the game with 3 hits is ignored the data becomes:
7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11a) The mean will increase.
With 3:
(3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9Without 3:
(7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21b) The median will remain as is.
With 3 and without the median is same = 9need some help...............

I dont see the whole question
Step-by-step explanation:
Answer:
Remember the relation:
Distance = Speed*Time.
Then if we define:
y = distance
x = time
Speed = 50km/hr
Then we can write the relation between distance and time is:
y = (50km/hr)*x
This is the equation we need to graph.
To graph it, we can just find two points of that equation, and then draw a line that connects them:
For example if we have x = 0hr then:
y = (50km/hr)*0hr = 0km
then we have the point (0hr, 0km)
If now we use the point x = 1hr, then:
y = (50km/hr)*1hr = 50km
Then we also have the point (1hr, 50km)
Now we can draw these two points and connect them by a line, that line is the graph of the equation.
The graph of the equation can be seen below:

Answer:
If we know that the equation of the line [tex]x = -2[/tex] is parallel to the y-axis.
Step-by-step explanation:
The equation of a line parallel to the y-axis is of the form [tex]x = a[/tex], where [tex]a[/tex] is the x-coordinate of the point of the line passing through the x-axis. Then, if we know that the equation of the line [tex]x = -2[/tex] is parallel to the y-axis.

The lenten on a map states that 1 inch is 40 miles. If you measure 5 inches on the map, how many miles would the actual distance be?
===============================================
Work Shown:
(1 inch)/(40 miles) = (5 inches)/(x miles)
1/40 = 5/x
1*x = 40*5 .... cross multiply
x = 200 miles
------------
We could also look at it like this:
1 inch = 40 miles
5*(1 inch) = 5*(40 miles) .... multiply both sides by 5
5 inches = 200 miles

if the pressure is 50 Pa and the mass of the object is 50 kg ,what is the surface area of the object?
Answer:
9.81m^2
Step-by-step explanation:
Given data
Pressure P= 50Pa
Mass M= 50kg
Weight= Mg= 50*9.81= 490.5N
Hence Force= 490.5N
We know that Pressure= Force/Area
Substitute
50= 490.5/Area
Area= 490.5/50
Area= 9.81 m^2
Hence the area is 9.81m^2

Answer:
r = 16, q = 16√2
Step-by-step explanation:
This is a 45° 45° 90° triangle. In this type of triangle, the legs of said shape will be equal and the hypotenuse will be the leg length multiplied by √2.
Therefore, r = 16 and q = 16√2.
Answer:
r = 16, c = 22.63
Step-by-step explanation:
tan 45° = 16/r
r = 16/ tan 45°
r = 16
c² = a² + b²
c² = 16² + 16²
c² = 256 + 256
c² = 512
c = 22.63

Two box and whisker plots showing Pre-Test and Post-Test scores on a number line from 0 to 100. The upper plot represents the pre-test scores. For this upper plot, the minimum number is 0, the maximum number is 78, the right side of the box is 60, the left side of the box is 16, and the bar in the box is at 30. The lower plot represents the post-test scores. For this lower plot, the minimum number is 4, the maximum number is 100, the right side of the box is 83, the left side of the box is 30, and the bar in the box is at 45.

Step-by-step explanation:
( - 6a³b + 2ab²)( 5a² - 2ab² b)
multiply the second parantheses by each term from the first parantheses.
-6a³b×(5a²- 2ab²b -b)+2ab×(5a² -2ab²b-b)
-6a³b× (5a² - 2ab² b) +2ab × (5a² - 2ab² b)
-30 a⁵b + 12a⁴b² + 6a³b²+ 10a³b² - 4a²b⁴ - 2ab
