Step-by-step explanation:
Hello There!
The shown figure is a trapezoid
The formula for area of a trapezoid is
where a = base 1
b = base 2
h = height
the dimensions given are
13 & 7 - bases
5 - height
so all we have to do is plug in the values into the formula
So we can conclude that the area of the trapezoid is 50 cm²
Answer:
1 1/2 + (-1/2) is also 1 1/2 - 1/2.
the result is 1 whole, and 1 whole is also the difference between 1 1/2 and 1/2.
Say you have half of a cheese piece, but your friend has 1 whole cheese piece plus half of a cheese piece.
He/She has 1 more cheese piece than you, right? That's the difference between you and your friend's cheese. 1 whole.
6x-5=4x+5
+5
6x=4x + 0
-4x
2x=0
x =0
probably to late but whatever
ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2
First we have to figure out how many hours have passed. Since 1PM also means 1300 hours, we'll subtract 9 from 13. 13-9=4. therefore, 4 hours have passed. if it gains 4 minutes every hour, we'll multiply the amount of hours that have passed by the amount the clock gains every hour. 4x4=16. now we subtract 16 from 1300 because the clock is ahead of the real time, but remember and hour only has 60 minutes! 1300-16=1244. Therefore, the correct time is 12:44PM.
