Answer:
Rate of change = 0.5
Initial value = 120
Step-by-step explanation:
(10 , 125) ; (30 , 135)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{135-125}{30-10}\\\\= \frac{10}{20}\\\\= \frac{1}{2}\\= 0.5[/tex]
Rate of change = 0.5
Initial value = 120

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle
Amy multiplied 2.20 by 75 to find my answer.”
220/100×75=2.2
His answer is correct
Barden
Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%
Braden is correct.
Colton created table for 100%, 10% and 10% percent and added these.
But this addition would result in 100+10+10 =120% not 220%
Hence Colton is wrong.
Danielle divided 75 by 5 to find 20%.
Then he added 75 twice to find his answer.
Danielle is correct.
Hence Colton got the wrong answer

Mr. Jamison will stain the deck in his backyard, the deck has an area of 752.4 sqaure feet. If the deck is 33 feet long how wide is it? Justify your procedure.
Answers
answer:The width of the deck is 22.8 feet.
Step-by-step explanation:
Since we have given that
Area of the deck = 752.4 square feet
Length of deck = 33 feet
Let width of deck be 'x'.
Since Deck is in the shape of rectangle.
As we know the formula for "Area of rectangle ":
\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}
Area=Length×width
752.4=33×x
33
752.4
=x
22.8=x
Hence, the width of the deck is 22.8 feet.

A school allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £25 each and are on offer for 1/5 off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip?
Answers
Answer:
40 students
Step-by-step explanation:
If the tickets are 1/5 that means they cost 4/5
25 * 4/5 = 20
The tickets cost 20 and the train costs 15 so the total per person is 35
Teachers: 2 at 35 = 70
1500 -70 = 1430
Take 1430 / 35 =40.85714286
We can send 40 students
Answer:
40
Step-by-step explanation:
since the school allots £1500 to spend on a trip to the theatre. Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off
therefore 4/5*35 = 28 for the tickets
:
A train ticket for the day will cost £15 each.
therefore total cost for each: 28 + 15 = 43 pounds each
:
If 2 teachers and the maximum number of students attend, how much money will the school have left over?
:
let s = no. of students
43(s+2) =< 1500
43s + 86 =< 1500
43s =< 1500 - 86
43s =< 1414
s =< 1414/43
s =< 32.88, 32 students max
:
find how much left over. plus 2 teachers = 34 people
1500 - 43(34) =
1500 - 1462 = 38 pounds left over

The graph below represents a recent 10 meter race between two remote control cars.
A graph titled Remote Control Car Race has seconds after race start on the x-axis and distance from start line (meters) on the y-axis. A line labeled red car goes through (3, 2) and (6, 4). A line labeled blue car goes through (3, 0) and (5, 2).
Which statements about the race are true? Check all that apply.
The red car won the race because it started above the blue car.
The cars crashed at 9 seconds into the race because that is the point of intersection, and neither car continued on after that point in time.
The blue car passed the red car at 6 m into the race because that is the point of intersection, and the blue car has a greater distance than the red car after that time.
The blue car is faster because the slope of its line is steeper than the slope of the line representiong the red car.
The blue car started 3 seconds late because it has an x-intercept of (3, 0) and x represents the time and y represents the distance from the starting line.

A recent 10-meter race between two remote-control cars is seen in the graph below. The race-related claims in A, B, and C are accurate.
What is a graph?A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
The correct statements are;
At 6 meters into the race, the blue car overtook the red car because, at that moment, the blue car had a bigger distance than the red car.
Due to the greater slope of the blue vehicle's path compared to the red car's line, the blue car is faster.
Because the blue car's x-intercept is at (3, 0), where x stands for time and y for distance from the starting line, it began 3 seconds later than the other cars.
Hence Statements B, C, and D about race are true.
