Answer:
4m (A)
Step-by-step explanation:
since normally you multiply everything to get volume, we can divide the things we have from volume to get missing side. 240/12 then divided by 5=4
Answer:
the height of the flagpole is three fourths the height of the school. the difference in there heights is 4.5 m. what is the height of the school?
----------
Equation:
f = (3/4)s
s-f = 4.5
----
Substitute for "f" and solve for "s":
s-(3/4)s = 4.5
(1/4)s = 4.5
s = 4*4.5
s = 18 meters (height of the school)
---------------
Since f = (3/4)s, f = (3/4)(18)
= (3/2)(9)= 13.5 meters (height of the flag pole)

Answer:
Step-by-step explanation:
first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get
2+5i+4i+10i^2
then in the next step add 4i and 5i you will get 9i
in the next step put i^2=-1 and you will get -10
in the last step just substract 2-10 you will get -8 and 9i
and your answer will be -8+9i
The least common denominator of 1/6 and 7/9 is 18. Why? Well, we can start by listing the multiples of both denominators (the numbers on the bottom of the fractions) which are 6 and 9.
Multiples of 6:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60
Multiples of 9:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90
By identifying the multiples of these numbers, we can see that the lowest multiple these integers have in common is 18. Because of this, the least common denominator of 1/6 and 7/9 is 18.
Your final answer: 18.
H = 215t - 16.t² or H = -16t² + 215t
97 = -16t² + 215t
-16t² + 215t - 97 = 0
solving this equation genes t' = 12.97 seconds and t" = 0.467??
