Answer
:2 X 0.018 = 0.036 (thirty six hundreds)
Step-by-step explanation:
The number behind the zero is bigger than 4 so you would round the zero up to a 1.
The answer would be 32.1
Answer:
7 1/2
Step-by-step explanation:
2 1/2 ÷ 1/3
Change the mixed number to an improper fraction
2 1/2 = (2*2+1)/2 = 5/2
5/2 ÷ 1/3
Copy dot flip
5/2 *3/1 = 15/2
Changing back to a mixed number
2 goes into 15 7 times with 1 left over
7 1/2
You can simplify the integrand:
![\dfrac{3x^2+4x+1}{2x}=\dfrac{3x}2+2+\dfrac1{2x}](https://tex.z-dn.net/?f=%5Cdfrac%7B3x%5E2%2B4x%2B1%7D%7B2x%7D%3D%5Cdfrac%7B3x%7D2%2B2%2B%5Cdfrac1%7B2x%7D)
Then integrate term-by-term:
![\displaystyle\int\frac{3x^2+4x+1}{2x}\,\mathrm dx=\frac32\int x\,\mathrm dx+2\int\mathrm dx+\frac12\int\frac{\mathrm dx}x](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint%5Cfrac%7B3x%5E2%2B4x%2B1%7D%7B2x%7D%5C%2C%5Cmathrm%20dx%3D%5Cfrac32%5Cint%20x%5C%2C%5Cmathrm%20dx%2B2%5Cint%5Cmathrm%20dx%2B%5Cfrac12%5Cint%5Cfrac%7B%5Cmathrm%20dx%7Dx)
![=\dfrac{3x^2}4+2x+\dfrac12\ln|x|+C](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3x%5E2%7D4%2B2x%2B%5Cdfrac12%5Cln%7Cx%7C%2BC)
She would run 1,140 meters in 6 minutes.
To use the formula d = r x t, we just need to plug in the rate and the time.
We will have:
distance = 190 x 6
d = 1140
