Answer:
3.5 days
Step-by-step explanation:
If it takes 7 pupils 5 days, then it would take 1 pupil 7 times as long, or 35 days.
1 pupil alone cleans the auditorium is 35 days.
10 pupils work 10 times faster than 1 pupil, so 10 pupils take 3.5 days.

An Uber ride costs a flat rate to start the ride and then charges an additional amount per mile. By the 3rd mile, the total cost of the trip is $9. By the 7th mile, the total cost is $17. What is the flat rate that Uber charges and how much does it cost per mile?
Step-by-step explanation:
the function is
ride cost c = mile rate r × miles m + flat rate f
c = r×m + f
now let's put the values in we know and solve for r and f :
9 = r×3 + f
17 = r×7 + f
now, since one term is the same in both equations, we use a simple trick for speed, and we subtract the whole first equation from the second :
17 = r×7 + f
- 9 = r×3 + f
-------------------
8 = r×4 + 0
r = 8/4 = $2
9 = 2×3 + f = 6 + f
f = $3
the first rate is $3, and it costs $2 per mile.
what is the equation to solve this

a hockey team earns 2 points for a win,1 point for a tie, and 0 points for a loss. the number of points earned can be calculated using this formula
P = 2x + y where P = number of points
x = number of wins
y = number of ties
How many points would a team earn if they played 52 games, won 24 and lost 19?
Answer: 57
Step-by-step explanation: First add the won and lost games then subtract the sum from the total games played to determine how many games were tied. Then take the won games and multiply them by 2, take the tied games, and add them together to get your answer: 57.
Which is bigger 12 cm or 102 mm
On comparing the quantities 12 cm or 102 mm, 12 cm (120 mm) is greater than 102 mm.
To compare the sizes of 12 cm and 102 mm, both numbers should have the same unit.
Now, the conversion factor cm and mm is
1 cm = 10 mm
Then, using the conversion factor convert 12 cm to mm
12 cm = 12 x 10 mm
= 120 mm
Now, compare 120 mm and 102 mm which gives 120 mm is greater.
Thus, 12 cm is greater than 102 mm.

Answer:
1. f(3) = 11
2. f( 1 ) = 6
3. f(-2) = -5
Step-by-step explanation:
Note: I will only work on questions 1 and 2 in order to allow you to practice the techniques provided in this post, as you work on question 3. However, I will provide the correct answer for question 3, as your reference.
In order to evaluate each of the given functions, simply substitute the inputs provided in the function notation, f(x).
1. f(x) = 2x + 5, find f(3).To evaluate the given linear function, simply substitute x = 3 as an input into the function:
f(3) = 2x + 5
f(3) = 2(3) + 5
f(3) = 6 + 5
f(3) = 11
Therefore, the value of f(x) = 2x + 5 given f(3) is: f(3) = 11.
2. f(x) = x² + 2x + 3, find f(1)Similar to question 1, substitute x = 1 as the input of the given quadratic function.
f(x) = x² + 2x + 3
f( 1 ) = ( 1 )² + 2( 1 ) + 3
f( 1 ) = 1 + 2 + 3
f( 1 ) = 6
Therefore, the value of f(x) = x² + 2x + 3 given f( 1 ) is f( 1 ) = 6.
3. f(x) = 3x² + 5x - 7, find f (-2)If evaluated properly, the correct answer is: f(-2) = -5.
is this true or false |-2.9|> 2.6
Hello! :)
I will start by explaining what the l l notation means.
It means "absolute value" or a number's distance from zero.
Absolute value is always positive. Remember this:
lal=a
l-al=a
Now, using this, let's solve our math problem.
l-2.9l>2.6
2.9>2.6
Is this statement true? Is 2.9 greater than 2.6? Yes, it is. Therefore, the statement is true.
Hope it helps.
Feel free to ask me if you have any questions.
~A smiley teen who adores helping others

Answer:
True
Step-by-step explanation:
The absolute value of -2.9 is 2.9.
So 2.9>2.6
Remember, the absolute value of a number is always nonnegative (positive or zero). If a number is negative, negating that number will make it positive.
Help!! Solve for X round to the nearest 10th
Step-by-step explanation:
remember : the sum of all angles in a triangle is always 180 degrees.
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C) with the sides being always opposite of the angles.
so,
the opposite angle of x is
180 - 90 - 58 = 32 degrees.
x/sin(32) = 11/sin(58)
x = 11×sin(32)/sin(58) = 6.873562871...
rounded x = 6.9

Equation of a Straight Line
1.1 Solve 3x-2y-27 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-2y-27 = 0 and calculate its properties
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 27/-2 so this line "cuts" the y axis at y=-13.50000
y-intercept = 27/-2 = -13.50000
Calculate the X-Intercept :
When y = 0 the value of x is 9/1 Our line therefore "cuts" the x axis at x= 9.00000
x-intercept = 27/3 = 9
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -13.500 and for x=2.000, the value of y is -10.500. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -10.500 - (-13.500) = 3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 3.000/2.000 = 1.500
Geometric figure: Straight Line
Slope = 3.000/2.000 = 1.500 x-intercept = 27/3 = 9 y-intercept = 27/-2 = -13.50000666.96358875 × 411.8596678
