BEST GETS BRAINLEST.A construction engineer needs to make 25 square concrete slabs with sides of length x feet and a height x - 3 feet. If the engineer can use at most 350,000ft^3 of concrete, what should the dimensions of each slab be, to the nearest foot?
a. Write an expression for the volume of all the slabs
b. What should x equal, to the nearest foot?
Answers
Answer:
x ≈ 118 ft
Step-by-step explanation:
To get an expression for the volume of all slabs, we can use the formula of volume of cuboid 'V', which is equal to the product of its length 'x', breadth 'x' and height 'x-3' i.e.
For 25 slabs,
Since, V cannot be more than 350,000 , therefore,
which can be written as:
either:
x ≈ 118 ft
or:
which is not possible.
Hence x should be 118 ft
Therefore, the area of the base =

The answer is A because you subtract 3 from both sides to get the equation set to 0
(f + g)(x) < 3 for all values of x
(f + g)(x) < 6 for all values of x
(f + g)(x) 6 for all values of x

Answer:
The answers are "(f+g)(x)> 3 for all values of x" and "(f+g)(x)<6 for all values of x".
Step-by-step explanation:
- If f(x) = 1x1 + 9 =10, then f(x) is a constant for every value of x, which means that y=f(x) will take the value of 10 no matter which value takes x.
- If g(x)= -6, then g(x) is a constant for every value of x, which means that it will take the value of -6 no matter the value of x.
- (f+g)(x)=10 + (-6) = 10 - 6= 4. Then, no matter the value of x, the function (f+g)(x) will equal 4 (a constant).
- According to the available options, both "(f+g)(x)>3" and "(f+g)(x)<6" are true, because (f+g)(x)=4>3 and (f+g)(x)=4 <6.

Answer:
X = 6
Step-by-step explanation:
Cross Multiplication
We can go about this 1 of 2 ways we can either cross multiply or divide across the numerators and denominators. Let's cross multiply. We would 4*9 = 6x. Which would simplify down to 36 = 6x. We would then divide the 6 on each sides of the equation to get 6 = X.
Dividing Across
The other way we can go about it is by seeing what 4 had to be multiplied by to get to 6. We do this by dividing 6 by for which gets us 3/2 or 1.5. Now that we know this we would then divide 9 by 3/2 or 1.5 to get the answer of 6.

Answer:
When adding fractions you want the denominators of your fractions to be alike.
The first thing you can do is add your two whole number 4 and 6. 4+6=10.
Now you want to combine your fractions, 3/8 and 3/4. Both fractions need to have like denominators. In order to do this we would change the 3/4 so it has a denominator of 8. I choose 8 because you can take 2*4 to get 8. Since we multiplied the denominator by 2, we have to do the same with the numerator, 3*2=6.
Your fraction is now 6/8.
We can down add 3/8 + 6/8= 9/8
Since 9/8 is improper we need to change it into a mixed number. In order to do this we need to take 9/8 which is 1 and 1/8
We now have 1 1/8 and don't forget the 10 from up above.
10+1 1/8= 11 1/8
Your final answer would be 11 1/8
Hope this helps ;)
