Answer:
306
Step-by-step explanation:
v = 1/3bh
2×(18×11 + 18×9 + 11×9) / 3 = 918/3
= 306
hope this helps, mark brainliest if it did luv gl !
Answer:
First you right the division as a fraction
1/5x=5
then mutiply both sides of the equation by 5
x=25
Step-by-step explanation:
Answer:
-9-(-3)/0-(-3) = -3/3 = -1
y+9= -1(x-0) <u><em>Point Slope form</em></u>
y+9<u>-9</u>= -1x<u>-9</u>
y= -x-9 <em><u>Slope Intercept form</u></em>
y<u>+x+9</u> = -x-9 <u>+x+9</u>
y+x+9= 0 <u><em>General form</em></u>
Answer:
![Average = 43.29](https://tex.z-dn.net/?f=Average%20%3D%2043.29)
Step-by-step explanation:
Given
Time: 44.64,43.45,42.79 and 42.28
<em></em>
Required
Determine the average time
Average or mean is calculated as thus;
![Mean = \frac{\sum x}{n}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
Where
= sum of observation
n = number of observation = 4
![Average = \frac{44.64 + 43.45 + 42.79 + 42.28}{4}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B44.64%20%2B%2043.45%20%2B%2042.79%20%2B%2042.28%7D%7B4%7D)
![Average = \frac{173.16}{4}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B173.16%7D%7B4%7D)
![Average = 43.29](https://tex.z-dn.net/?f=Average%20%3D%2043.29)
<em>Hence, the average time is 43.29</em>
