13)
Circumference (C) = 2π·r
11π = 2π·r
11/2 = r
******************************
Area (A) = π·r²
= π·(11/2)²
= 121π/4
≈ 94.985 in²
14)
diameter = 2r
42 = 2r
21 = r
*******************
Area (A) = π·r²
= π·(21)²
= 441π
≈ 1384.74 in²
***************************
$280/1384.74 in²
x = $0.20
Answer: about 20 cents per square inch
Answer:
the answer is 3.81
but rounding it it will be 3.8 meters
Step-by-step explanation:
Pythagorean theorem says
a²+b²=c²
so,
take take the Lowest measurement as a² which will be 7 and take 8 as the hypotenuse or the longest side which is c²
then put it all together you get
7²+x²=8²
we made b as x because we will be finding b
then substitute the values
x²=8²-7²
x²=64-49
x²=15
to remove that square from the x you then put square root in both
✓x²=✓15
press in the calculator, root of 15 will be about 3.81
now we got
x=3.81
x is the missing measurement
Answer:86
Step-by-step explanation
140-(16+24+5+9) 140-54 = 86
Answer:
Her account balance will be $2,080 at the end of the year
Step-by-step explanation:
Let
y ----> Susannah's account balance
x ---> is the amount of time in months
we have
This is a linear equation in slope intercept form
where
The slope or unit rate is equal to
The y-intercept or initial value is equal to
Remember that
One year is equal to 12 months
so
For x=12 months
substitute in the linear equation
