For a triangle the area is given as:
![A=\frac{bh}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bbh%7D%7B2%7D)
Re-arrange / solve for 'h':
![h=\frac{2A}{b}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B2A%7D%7Bb%7D)
Substitute known values:
![h=\frac{2(60m^{2})}{15m}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B2%2860m%5E%7B2%7D%29%7D%7B15m%7D)
Compute:
![h=\frac{120m^{2}}{15m}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B120m%5E%7B2%7D%7D%7B15m%7D)
Answer:
455 miles driven in 7hrs
Step-by-step explanation:
715miles divided by 11 hrs= 65 miles per hr
65 miles multiplied by 7 hrs= 455 miles driven in 7hrs
Answer:
Consecutive angles will always some to 180 degrees, that makes consecutive angles in a parallelogram supplementary
Answer:
![89.86\times 10^6](https://tex.z-dn.net/?f=89.86%5Ctimes%2010%5E6)
Step-by-step explanation:
![9.3\times 10^7 - 3.14\times 10^6\\](https://tex.z-dn.net/?f=9.3%5Ctimes%2010%5E7%20-%203.14%5Ctimes%2010%5E6%5C%5C)
In order to simplify the above expressions we make sure that we get same powers of 10 for both the terms.
So, we multiply and divide the first term with 10
Dividing first term by 10.
![\frac{9.3\times 10^7}{10}\\9.3\times 10^{7-1}\\9.3\times 10^6\\](https://tex.z-dn.net/?f=%5Cfrac%7B9.3%5Ctimes%2010%5E7%7D%7B10%7D%5C%5C9.3%5Ctimes%2010%5E%7B7-1%7D%5C%5C9.3%5Ctimes%2010%5E6%5C%5C)
Now multiplying it by 10.
![10\times9.3\times 10^6\\93\times 10^6](https://tex.z-dn.net/?f=10%5Ctimes9.3%5Ctimes%2010%5E6%5C%5C93%5Ctimes%2010%5E6)
Evaluating the new expressions.
![93\times 10^6 - 3.14\times 10^6\\](https://tex.z-dn.net/?f=93%5Ctimes%2010%5E6%20-%203.14%5Ctimes%2010%5E6%5C%5C)
Taking
common factor out.
![(93-3.14)\ties 10^6](https://tex.z-dn.net/?f=%2893-3.14%29%5Cties%2010%5E6)
![=89.86\times 10^6](https://tex.z-dn.net/?f=%3D89.86%5Ctimes%2010%5E6)
Answer:
0.2 = y
Step-by-step explanation: You have to isolate y
<u> 7 = 35y</u>
35 35
0.2 = y
RECHECK:
7 = 35y
7 = 35(0.2)
7 = 7
YES, this is a true statement.
Hope this helps you!!! :)
