Answer:
x=83
Step-by-step explanation:
97+x=180
x=83
572.
13 percent *4400 =
(13:100)*4400 =
(13*4400):100 =
57200:100 = 572
Y=((square root of 2)+1)


1) (y-1)^2 =2
so we can concludes that y-1 = squareroot of 2
so ((squareeroot of 2+1) - 1)^2 = 2
2)First we can convert 21÷2 fraction to decmial form which is 10.5
so our equation would be (c+1)^2= 10.5
so c+1 is the sqaureroot root of 10.5
so c would be the (square root of 10.5)-1
3)We can again convert those fractions to decimals so 3/2=1.5 and 71/4 =17.75
so our equation would be (e-1.5)^2=17.75
so (e-1.5) is the square root of 17.75
so e=((square root of 17.75)+1)
Answer:
39.4384
Step-by-step explanation:
C= 2(pi)(r)
C=2(3.14)(9)
39.4384=2(3.14)(9)
