what is one way to find the number of minutes in 7 hours?
Answer:
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.

{[(3x+8)+6(2.5x-3)]}
Answer: The answer is 18x + 26
Step-by-step explanation:
What I did was simplify the Expression of (3x+8)+6(2.5x-3) then combine the terms and last evaluate the Expression.
Here's a question ~
can anyone give the explanation ?
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

by what percentage did the high temperature increase from friday to saturday ? round ur answer
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%

In the figure below, if m<1 = (x + 16)° and m
The < sign is angle
Answer:
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

Triangle PQR has vertices P(-2,2), Q(8,2) and R(4,6).
(a) Find the equation of the perpendicular bisector of segment PQ.
I got so confused on this question if I could get help it would mean a lot
9514 1404 393
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 ...
x = 3
