Answer:
C. 161.459 square feet
Step-by-step explanation:
In feet, the dimensions of the pool are ...
(5 m)(3.28084 ft/m) = 16.4042 ft
(3 m)(3.28084 ft/m) = 9.84252 ft
Then the area of the pool is ...
(16.4042 ft)(9.84252 ft) = 161.458666584 square feet
about 161.459 square feet
_____
<em>Additional comment</em>
If you consider that a square meter is slightly less than 11 square feet, the pool area can be estimated to be (5 m)(3 m)(11 ft²/m²) = 165 ft². This is close enough to point you to the correct answer choice.
Answer:
68
Step-by-step explanation:
Use the formula provided...
6 and 11 are b1 and b2, and 8 is h.
So, 6+11 = 17
17/2 = 8.5
8.5*8 = 68
Step-by-step explanation:
m1 * m2 = -1
-4/3 * m2 -1
m2 = 3/4
y - 4 = 3/4 ( x - 5)
y = 3x/4 - 15/4 + 4
y = 3x/4 - 1/4
y = 1/4 (3x - 1)
D. (5/9v - 5/9)
<u>Step-by-step explanation:</u>
(2/9v)- (-1/3v+ 5/9)
Since it is subtraction, we have to change the sign of the second expression that is after the (-) sign.
= (2/9v + 1/3v - 5/9)
Since we have different denominators, we have to take LCM of 3 and 9 as 3, so the expression becomes,
= (2/9v + 3/9v - 5/9)
= (5/9v - 5/9)
