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:
-24
Step-by-step explanation:
I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,
so 6*2=12,8*-3=-24,-3*2=-6
12+-24-6-6,
12-24=-12,-6+-6=-12
-12+-12=-24
The correct answer is the letter A because a division problem shows a total amount being broken into equal parts.
Choice a talks about how many parts it would take to get the total of 212 m of ribbon.
This choice includes the parts and total information.
