Answer:
i dunno
Step-by-step explanation:
Answer:
first of all square mean two number or double so if we multiple 15×15=225 and if we multiply 16×16=256 mean the number 240 lies between them what about number 15.5 lets try now 15.5×15.5=240.25 if you want to make sure so just take a square root of this number
so 240 is product of (15.5)² note number after point is negligible
(.75*12)*3= 27 hopefully that’s correct!
Answer:
<h2>254.5 in^2</h2>
Step-by-step explanation:
Given that the circumference of the frame is 56in
we can proceed to obtain the radius of the frame
we know that
circumference= 2πr
56= 2*3.142*r
56= 6.284r
divide both sides by 6.284
r= 56/6.284
r=8.9
approximately radius is 9in
therefore the area of the mirror that is largest would be
Area= πr^2
Area= 3.142*9^2
Area= 3.142*81
Area= 254.5 in^2
The largest area is 254.5 in^2
Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when then:
