Answer: 3.18
Step-by-step explanation:
Trust i took this test
The surface area not including the top of the pool would be 748 ft(not sure if the teacher want you to add square to the end of it or not) .so 12*5 is 60 ,*2 =120. 24*5 =120. 120*2= 240. 24*12=288. so 288+240+120=748 ft(this would be the surface area of the pool.so if you need the volume of concrete needed to make the pool times the needed with of the concrete by the area ∆make sure if the needed thickness needed is in inches turn the area from feet to inches by multiplying it by 12 )
Answer:
No they are not equal;
a = -13
Step-by-step explanation:
Here, we want to find the value of a
We are gong to use the ratio given
That will be;
a + 3/ 7 + a = 4/5
5(a + 3) = 4(7 + a)
15 + 3a = 28 + 4a
4a - 3a = 15-28
a = -13
19975 is your answer hopefully this helps!
Answer:
45 or two decimal points 45.167.
Step-by-step explanation:
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be
