A because D is less than or equal to, C is saying that 9 is bigger than 12 and B is incorrect because the sign is going to point towards the bigger number
Mass = density x volume
1st we need to get the volume
V = (25*10^-1) * (1.8) * (3)
V = 13.5 cm3
mass = 2.53 * 13.5
mass = 34.155 kg
Answer:
<em>Michael drove faster than Jordan.</em>
Step-by-step explanation:
<u>Speed</u>
The speed is the ratio between the distance d traveled by an object and the time t it took to move. In terms of a mathematical equation, it's expressed as:
![\displaystyle v=\frac{d}{t}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v%3D%5Cfrac%7Bd%7D%7Bt%7D)
Michael drove 210 miles in 3 and one-half hours. The parameters to calculate the speed are: d= 210 miles, t = 3.5 hours. The speed of Michael is:
![\displaystyle v_M=\frac{210}{3.5}=60\ mi/h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v_M%3D%5Cfrac%7B210%7D%7B3.5%7D%3D60%5C%20mi%2Fh)
Jordan drove 330 miles in 6 hours, thus his speed is:
![\displaystyle v_J=\frac{330}{6}=55\ mi/h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v_J%3D%5Cfrac%7B330%7D%7B6%7D%3D55%5C%20mi%2Fh)
It's clear that Michael drove faster than Jordan.
The given equality hold true when x = 2.
Put x = 2 in inequality.
2(2) + 3 = 4+3 = 7 = R.H.S.
For x = 4 and 6, L.H.S(2x+3) is greater than 7.
Hence for x = 2, 4 and 6, the above inequality holds true.
Hope this helps!
Answer:
x= 55
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+70 =180
Subtract 70 from each side
2x+70-70=180-70
2x= 110
Divide by 2
2x/2 = 110/2
x= 55
