If 1,200 cm2 of material is available to make a box with a square base and an open top, find the maximum volume of the box in cubic cm. For example, if the answer is 2,000 cm3 write 2000.
Answer:
4000cm³Step-by-step explanation:
Volume of the rectangular box = x²h
Surface area S = x²+4xh
x is the side length of the square base
h is the height
Given
Surface area = 1200cm²
Substitute into the formula S = x²+4xh
1200 = x²+4xh
From V = x²h
h= V/x²
1200 = x² + 4x (V/x² )
1200 = x² + 4V/x
1200x = x³ + 4V
1200x - x³ = 4V
V = 1200x/4- x³/4
V = 300x - x³/4
To maximize the volume, dV/dx = 0
dV/dx = 300 -3x²/4
0 = 300 -3x²/4
0 = 1200 - 3x²
3x² = 1200
x² = 400
x = 20cm
Since 1200 = x²+4xh
1200 = 400+80h
80h = 1200-400
80h = 800
h = 10cm
Find the volume;
Volume = 400 * 10 Volume -= 4000
Hence the maximum volume of the box in cubic cm is 4000 cm³

Find the sum of the arithmetic progression 1,4,7,10,13,16 .Every third term of the above progression is removed i.e 7,16. Find the sum of the remaining terms
Answer:
The sum of the arithmetic progression is 51
The sum of the remaining terms is 28
Step-by-step explanation:
Sum of terms of an arithmetic progression
Being a1 the first term of an arithmetic progression, an its last term, and n the number of terms, the sum of all terms is calculated as:
[tex]\displaystyle S_n=\frac{a_1+a_n}{2}\cdot n[/tex]
We are given the progression:
1,4,7,10,13,16
We need to check if the list of numbers is a progression. The difference between consecutive terms must be equivalent.
Since:
4 - 1 = 3
7 - 4 = 3
10 - 7 = 3
And the rest of the differences also result in 3, the series of numbers has a common difference of 3.
The progression has the following parameters:
a1=1, an=16, n=6
Let's find the sum:
[tex]\displaystyle S_6=\frac{1+16}{2}\cdot 6[/tex]
[tex]\displaystyle S_6=\frac{17}{2}\cdot 6[/tex]
[tex]S_6=51[/tex]
The sum of the arithmetic progression is 51
If we removed the terms 7 and 16, the new sum is:
51 - 7 - 16 = 28
The sum of the remaining terms is 28
The fair charges an entrance fee of $10, and each ride costs $2. 1) Write an equation relating number of rides r, to the total cost of attending the fair C. 2) What is the dependent variable? 3) What is the independent variable?
Answer:
1) y = $10 + $2x
2) independent variable is the number of rides (x)
3) dependent variable in this equation is the total cost (y)
Step-by-step explanation:
In this scenario, we have two fixed values and two variables which would be the number of rides (x) and the total cost (y). Therefore, since the entrance fee is a fixed value it is added to the cost of each ride which is multiplied by the number of rides represented by the variable (x).
y = $10 + $2x
In this equation, the independent variable is the number of rides (x) because it is a separate value from the equation and does not depend on any other value. The dependent variable in this equation is the total cost (y) which depends on the number of rides that the individual goes on in order to have its own value.

Answer:
x = 2
Explanation:
[tex]\frac{3x-1}{5} =\frac{x+1}{3}[/tex]
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
[tex]\frac{3*(3x-1)}{3*5}[/tex] = [tex]\frac{3(3x-1)}{15}[/tex]
Next, multiply the numerator and denominator of the second fraction by 5.
[tex]\frac{5*(x+1)}{5*3}[/tex] = [tex]\frac{5(x+1)}{15}[/tex]
Now we have: [tex]\frac{3(3x-1)}{15} =\frac{5(x+1)}{15}[/tex]
Use distributive property on the numerators of both fractions.
[tex]\frac{9x-3}{15} =\frac{5x+5}{15}[/tex]
Since the denominators are equal we can ignore them for now and find x.
9x - 3 = 5x + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5x from both sides.
9x - 5x - 3 = 5x - 5x +5
4x - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4x - 3 + 3 = 5 + 3
4x = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
x = 2

Factor the expression using the GCF. 76d-24=
Answer:
Factoring the expression [tex]76d-24[/tex] using the GCF we get [tex]\mathbf{4(19d-6)}[/tex]
Step-by-step explanation:
We need to factor the expression using the GCF : [tex]76d-24[/tex]
GCF stands for greatest common divisor.
We need to find the greatest number that is divisible by both terms.
The greatest number that is divisible by both terms is 4
So, Now factoring the term:
[tex]76d-24\\=4(19d-6)[/tex]
So, factoring the expression [tex]76d-24[/tex] using the GCF we get [tex]\mathbf{4(19d-6)}[/tex]

How to find the square root of 40 by long division method
Here we will show you how to calculate the square root of 40 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 40 by hand before modern technology was invented.
Step 1)
Set up 40 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
40 00
Step 2)
Starting with the first set: the largest perfect square less than or equal to 40 is 36, and the square root of 36 is 6. Therefore, put 6 on top and 36 at the bottom like this:
6
40 00
36
Step 3)
Calculate 40 minus 36 and put the difference below. Then move down the next set of numbers.
6
40 00
36
4 00
Step 4)
Double the number in green on top: 6 × 2 = 12. Then, use 12 and the bottom number to make this problem:
12? × ? ≤ 400
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 3. Now, enter 3 on top:
6 3
40 00
36
4 00
That's it! The answer is on top. The square root of 40 with one digit decimal accuracy is 6.3.

What is the value of x in the solution to this system of equations?
4x+7y=85
x=2y−5
A. x = -9
B. x = 9
C. x = 8
D. x = 3
Answer:
B
Step-by-step explanation:
I used substitution to solve this system. I'll run through all of my steps below:
[tex]4x+7y=85\\x=2y-5[/tex]
I'm going to replace the 'x' values in the first equation with the entire second equation.
[tex]4(2y-5)+7y=85[/tex]
[tex]8y-20+7y=85\\15y-20=85\\15y=105\\y=7[/tex]
Now that we know what y equals, we can go back and solve for x.
[tex]x=2(7)-5\\x=14-5\\x=9[/tex]
Hope this helps!

can you feel in the blanks
Answer:
First blank would be 25, Second blank would be 75.
Step-by-step explanation:
In order to figure out the blanks, we must figure out the original function first.
How do we do that?
-> we put in the points that we already have- in to equation:
y = ax + b
If we put the 6, 10 in to x, y , we would get :
10 = 6a + b
If we put the 12, 20 in to x, y , we would get :
20 = 12a + b
because these share the "+b" they can be subtracted.
10 = 6a + b
- 20 = 12a + b
--------------------------------------
and this would be :
-10 = -6a, a = 5/3.
we can partly complete the equation.
y = 5/3x + b, and by putting in the numbers, we can figure out that b=0.
The full equation have : y = 5/3x
now, put 15 and 45 in to the x and see what you get!
y=25, 75
Have a nice day :)
