Step-by-step explanation:
so, 80 L can get out of the tank every minute.
how long for 4800 L ?
that simply means "how many minutes for 4800 L ?"
and this we get by dividing 4800 by 80 (to see how often 80 fits into 4800) :
4800 / 80 = 60 minutes
so, it takes 60 minutes or 1 hour to discharge 4800 L.

Answer:
x = 34
Step-by-step explanation:
1/4(x - 2) + 4 = 12
Subtract 4 from both sides.
1/4(x - 2) = 8
Multiply both sides by 4.
x - 2 = 32
Add 2 to both sides.
x = 34

SkandarLine l passes through point (-4,47) and line p is the graph of y+1=-5(x+5). If l is parallel to p what is the equation of l?
Answer:
[tex]y _{ \rm parallel} = - 5x +27[/tex]
Step-by-step explanation:
The equation of line p is in point-slope form , that's
[tex]y-y_1=m(x-x_1)[/tex]
Where:
m is the slope[tex](x_1,y_1)[/tex] is a point that lies on the lineSince line I is parallel to the line p , line I has the same slope as p. From the given equation of p , we can consider the slope of line p -5. Hence the slope of line I is also -5.
Now To determine the equation of I.
Use the point-slope formplugin the value of m and [tex](x_1,y_1)[/tex] to the equationsimplify it to the slope intercept form.We have
[tex](x_1,y_1)[/tex] =(-4,47)[tex]m_{parallel}=-5[/tex]So, the equation of line l is
[tex] y - 47 = - 5(x - ( - 4)) \\ \implies y - 47 = - 5 x- 20 \\ \implies \boxed{y _{ \rm parallel} = - 5x + 27}[/tex]

Applying the linear pair postulate, m<SQR = 74°.
What is the Linear pair Postulate?According to the linear pair postulate, the equation below is holds true:
m<TQS + m<SQR = 180.
m<TQS = (3m + 1)°
m<SQR = (2m + 4)°
Substitute the values
(3m + 1) + (2m + 4) = 180
Solve for m
3m + 1 + 2m + 4 = 180
Add like terms
3m + 2m + 1 + 4 = 180
5m + 5 = 180
Subtract 5 from both sides of the equation
5m + 5 - 5 = 180 - 5
5m = 175
m = 35
m<SQR = (2m + 4)° = 2(35) + 4 = 74°.

Express the mass of 49,000 molecules of oxygen in scientific notation.
grams
The scientific notation for the mass of 49,000 molecules of oxygen is 4.9 × 10⁴ grams.
How do you define the scientific notation?To transform numbers into scientific notation, use the following rule: In scientific notation, the exponent equals the number of times the decimal point must always be shifted to produce a number between 1 and 10.
The proper scientific notation format is an x 10∧b, where an is a number or decimal number with an absolute value greater or equal to one and less than ten, or 1 |a| 10.Scientific notation is a method of writing extremely large or extremely small numbers in a way that makes them easier to read as well as work with. A number formed by multiplying a number greater or equal to one but less than ten by an integral power of ten.For the given value;
= 49,000 grams
write the number such that only one digit is left to the left of decimal of the number and the remaining digits to the write are written to the power of 10
= 4.9000 × 10⁴
This could be written as;
= 4.9 × 10⁴.
Therefore, the value of the mass of 49,000 oxygen molecules in the form of scientific notation is 4.9 × 10⁴ grams.

To find a baseball pitcher's earned run average (era), you can use the formula ei = 9r, in which e represents era, i represents the number of innings pitched, and r represents the number of earned runs allowed. solve the equation for e. what is a pitcher's era if he allows 33 earned runs in 45 innings pitched? if necessary, round your answer to the nearest hundredth.
The value of e is 33/5 or 6.6 era.
It is given in the question that:-
e*i = 9r
Where,
e represents era
i represents the number of innings pitched, and
r represents the number of earned runs allowed
Also, we are given that:-
i = 45 innings, and
r = 33 earned runs allowed
We have to find the value of e for the given data.
Hence, applying the formula given in the question, we get
e*45 = 9*33
Now, as only one variable is left in the equation, it has become a linear equation in one variable.
Hence, solving the linear equation, we get

Parallelogram WXYZ is shown on the coordinate plane.
Parallelogram W’X’Y’Z’ (not shown) is the reflection of parallelogram WXYZ across the y-axis. Which statement is true?
W'X' is parallel to W'Z'
W'X' is parallel to Z'Y'
W'X' is perpendicular to W'Z'
W'X' is perpendicular to Z'Y'
The reflection transformation of the given diagram means that; W' X' is parallel to Z' Y'
How to Interpret Transformation Reflection?
Reflection over y-axis is a reflection or flip over the y-axis where the y-axis is the line of reflection used. The formula for this is: (x,y) →(−x,y) ( x , y ) → ( − x , y ) .
To reflect an equation over the y-axis, simply multiply the input variable by -1: y=f(x)→y=f(−x) y = f ( x ) → y = f ( − x )
Thus, looking at the given image and applying the transformation rule above, we can say that the reflection of parallelogram WXYZ across the y-axis would mean that W' X' is parallel to Z' Y'

It determines the centroid, incenter, and excenters of a triangle.Let P be the point that is 3/10 of a way from A to B. This means that it divides P in the ratio 3:10 = AP/PB = 3/10.
To find the coordinates, use the internal division formula, which is given as:
