The answer is C because is n is positive and even it will only open up.
Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
The area of a rectangle equals length times height. (A=LH)
A=256.5 L=18
Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)
next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.
So, it is 256.5/18 equaling H
256.5 divided by 18 is... 14.25
That means the height is 14.25 an the length is 18.
the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.
So you have two sides that are 14.25 and two that are 18 meters long.
14.25+14.25+18+18 equals the perimeter then.
So the answer would be... 64.5!
N=(3/4)*h*d
--------------------
n=Number of hours she reads
h=Hour(s)
d=Days
--------------------
You see, with this formula - when d=2,
n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours
So, in the space of 2 days, she had spent 1.5 hours reading.
