Answer: 375
Step-by-step explanation:
Since we are given the information that there are 250 bricks used to build a wall 20 feet high, the number of brick used per feet will be:
= 250/20
= 12.5 bricks per feet.
Therefore, the number of bricks that will be used to buld a wall that is 30 fet high will be:
= 12.5 × 30
= 375 bricks.
Therefore, 375 bricks would be used.
Answer:
F: 3(3.4) = 10.2- FALSE
G: 3.9(3.4) = 13.26- FALSE
H: 5(3.4) = 17- FALSE
J: 2.5(3.4) =8.5- TRUE
J is true.

Answer:
the answer is option E.
Step-by-step explanation:
it is in the form f/g (x).
we know f and g from the equation;
we can rewrite it as, (√(9-x^2)/(3x-1))
if you notice you cannot put any number less than -3 or greater than 3 in the numeror because if you do you get a negative root which is false. for instance if you put 4 or -4 in the numerator you get 9 - (4 or -4 square ) which is 9- 16 which is a negative number and you cannot take root of a negative number.
on the numerator if you put 1/3 as the value for x you will get zero in the denominator. and any number divided by zero is undefined so that cannot be.
this means that option E is the right one that satisfies the condition. it means the domain is [-3, 1/3) U (1/3, 3] .
Answer:
Two solutions were found :
x =(12-√132)/6=2-1/3√ 33 = 0.085
x =(12+√132)/6=2+1/3√ 33 = 3.915
