by what percentage did the high temperature increase from friday to saturday ? round ur answer
Answers
Answer:
Step-by-step explanation:
First, you must find the actual decrease in temperature.
Decrease = Yesterday's temperature - Today's temperature
Decrease = 80 - 75
Decrease = 5 degrees
Now, find the percentage decrease.
% Decrease = Actual decrease / Yesterday's temperature x 100
% Decrease = 5/80 x 100
% Decrease = 0.0625 x 100
% Decrease = 6.25 %
So, the percent decrease in high temperature from yesterday to today is 6.25%

Answer:
x = 3
Step-by-step explanation:
You can forget about point R. It does not have any part in this problem, except to add confusion.
The given line PQ has the same y-coordinate values for points P and Q. This means the segment is a horizontal segment. Its perpendicular bisector will be a vertical line through its midpoint.
The midpoint (M) of PQ is ...
M = (P +Q)/2
M = ((-2, 2) +(8, 2))/2 = (-2+8, 2+2)/2 = (6, 4)/2
M = (3, 2)
The vertical line through a point with x-coordinate 3 will have the equation ...

estaba previsto destinar 3/14 de partes de una finca a plazas de aparcamiento pero finalmente han destinado 3/4 de lo previsto a zonas ajardinadas que fraccion de la finca se ha destinado a plazas de aparcamiento
Answers
Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.
La solución es:
La fracción de la finca que se destina a plaas de aparcamiento es 3/56
Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.
Es decir, se destino 3/4 de los 3/14 del total de la finca a zonas ajardinadas, entonces el 1/4 restante se dedico a plazas de aparcamiento, esto da:
(1/4)*3/14 = 3/56
La fracción de la finca que se destina a plaas de aparcamiento es 3/56

This is much easier to solve actually since both expressions have the same denominator.
To solve it therefore,just sum the numerators

Factorize both numerator and denominator

Answers
Xavier(x), Yosef(y), Zeke(z).
x+y+z=56
y+z=x
(y/2)-2=z
we plug in for z to solve for y
y+(y/2)-2=x
Combine like terms
1.5y-2=x
Plug in for x and z in terms of y in the original problem
1.5y-2+y+.5y-2=56
Add like terms
3y-4=56
Add 4 from both sides
3y=60
Divide both sides by 3
y=20

Step-by-step explanation:
∠1 + ∠BFE = 180 {linear pair}
x + 16 + 3x + 20 = 180
x + 3x + 16 + 20 = 180 {Combine like terms}
4x + 36 = 180
Subtract 36 from both sides
4x = 180 - 36
4x = 144
Divide both sides by 4
x = 144/4
x = 36

Answer:
b= 3a-c
Step-by-step explanation:
Solve for b.
a= 1/3(b+c)
multiplying both sides by 3.
3a= b+c
subtract c from both sides.
3a-c=b
or
b= 3a-c
Answer:
b= 3a-c
Step-by-step explanation:
Solve for b.
a= 1/3(b+c)
Multiplying both sides by 3.
3a= b+c
Subtract c from both sides.
3a-c=b
or
b= 3a-c

Answer:
See belowStep-by-step explanation:
As per the question we have:
The y - intercept is b = -1The slope has same angle with x- and y - axis.This can be a function with the slope of m = 1 or m = - 1 as these lines must be perpendicular to each other and make 90°/2 = 45° or 45° + 90° = 135° angle with the x- or y- axis.
So the lines could be:
y = x - 1 ory = -x - 1Lines must be perpendicular to each other as they are cutting at y intercept -1
Slope intercept form of line
for slope -1
y=-x-1For slope 1
y=x-1

Seven dived by 60
Step-by-step explanation:
60 minutes makes an hour, so if you divide 7 hours by 60 minutes you could easily get an answer.
Multiplication.
because 1 hour = 60 minutes
and for you, there is 7 hours, you'd just do 7 x 60.
The answer would be the number of minutes (in those seven hours).
7 x 60 is 420 minutes just in case you were wondering.
Sienna, Rhys, and Micah are all reading the same book for school. Sienna has read 40% as far as Rhys has, and Rhys has read 40% as far as Micah has. If Sienna has read 60 pages, how many pages has Micah read?
Answers
Based on the fact that Sienna has read 60 pages, we can infer that Micha has read 375 pages of the book.
Sienna has read 40% of what Rhys has read and that corresponds to 60 pages. The number of pages read by Rhys is therefore:
= Number of pages / Percentage read
= 60 / 40%
= 150 pages
The 150 pages read by Rhys is 40% of what Micah has read. Micah has therefore read:
= 150 / 40%
= 375 pages
In conclusion, Micah has read 375 pages.

For the reaction 2Fe + O2 → 2FeO, how many grams of iron oxide are produced from 42.4 mol of iron?
Answers
In the balanced reaction
2 Fe + O₂ → 2 FeO
2 moles of iron (Fe) react with 1 mole of molecular oxygen (O₂) to produce 2 moles of iron oxide (FeO). The ratio of Fe to FeO is 1-to-1, so if one starts with 42.4 mol of Fe, one will end up with the same amount of FeO, 42.4 mol.
Look up the molar mass of Fe and O:
• Fe = 55.845 g/mol
• O = 15.999 g/mol
Then the molar mass of FeO is approximately 71.835 g/mol, and so the mass of 42.4 mol of FeO is
(42.4 mol) × (71.835 g/mol) ≈ 3050 g
