Our goal is to find the area
area=1/2 times base times height
we know the height is 7.9 but what is the base?
use the pythagorean theorem twice
alrighty
so
remember for legs length a and b and hytponuse c in a right triangle
a²+b²=c²
we need AD and DC
so
AD²+7.9²=9.4²
AD=√25.95
DC²+7.9²=23.2²
DC=√475.83
so
AD+DC=base=(√25.95)+(√475.83)
area=1/2bh
area=1/2((√25.95)+(√475.83))(7.9)
area≈106.28518654591426812803776879893
round to 2 decimal places
area≈106.29 square units
Answer:
x < -16, none of the solution sets are correct for the given equation.
Step-by-step explanation:
-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.
x < -16
none of the solution sets are correct for the given equation.
X+y=11
22x+15y=228
y=11-x
22x+15y=228
22x+15(11-x)=228
22x+165-15x=228
7x+165=228
7x=63
x=9
9+y=11
y=2
The solution to the system of equations is (9,2)
Answer:
9^-3= .0013717421
Step-by-step explanation:
Y=14x
Compare with general form:
y=kx
Where k is the constant of proportionality.
Here k=14
So 1 unit increase in x will bring 14 times increase in y.
There is a direct relation between x and y.
Answer: Yes
