A box is 15 x 20 inches. In the box there are cut out squares of the same size from each corner. Mark the side of the cut-out square by x. write an expression of the length of the box.
Answer:
İt is solved by using derivative
The edges of box are 20–2x,15–2x and x
Volume=(20–2x).(15–2x).x
İf you take derivative and then find the roots of derivative we obtain exstramum points that means these values make volume maximum or minimum
But
Answer is not rational
Answer:
A = 300-x^2 for area
A = 20L * 15 -x^2 for area
20L - x^2 = 300 - x^2 /15 -x^2 could also work to find length .
SIMPLIFIED
L - x = 300/20 - ( x^2 )/ 15 - x
Step-by-step explanation:
Length = L = 20 inches.
Area of one side = A = 15 X 20 = 300 cm^2
= 300 - x^2
This means the missing corner square is also squared
Simplifies to sqrt 300 - x
but as length was asked 20L * 15 -x^2
we know one side may be 15x 15
and if one side is 15 x 20
then instead of 15 x 15 it may be 15 x 20
eitherway we are looking at one side representing area of one side of the box. 300-x is our answer.

Answer:
[tex]x = 10°[/tex]
[tex]z = 66°[/tex]
Step-by-step explanation:
[tex](9x - 24)° + (12x - 6)° = 180°\\21x° - 30° = 180° \\ 21 x° = 180° + 30° \\ 21x° = 210° \\ x° = \frac{180°}{30°} \\ x° = 10°[/tex]
z° = 9x - 24 ( vertically opposite )
z° = 9(10) - 24
z° = 90 - 24

Answer:
K < - 16
Step-by-step explanation:
[tex]\frac{2k-3}{-5}[/tex] > 7
Multiply both sides by - 5 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.
2k - 3 < - 35 (add 3 to both sides )
2k < - 32 ( divide both sides by 2 )
k < - 16

From the large data set, the daily total sunshine, s, in Leeming during June 1987 is record.
The data is coded using x = 10s + 1 and the following summary statistics are obtained.
n = 30
Find the mean and standard deviation of the daily total sunshine
ΣΧ =
x=947
S = 33 065.37
XX
Find the mean and standard deviation of the daily total sunshine.
The coding of the statistic is used to make it easier to work with the large sunshine data set
The mean of the sunshine is 3.05[tex]\overline 6[/tex]The standard deviation is approximately 18.184Reason:
The given parameters are;
The sample size, n = 3.
∑x = 947
Sample corrected sum of squares, Sₓₓ = 33,065.37
The mean and standard deviation = Required
Solution:
[tex]Mean, \ \overline x = \dfrac{\sum x_i}{n}[/tex]
The mean of the daily total sunshine is therefore;
[tex]Mean, \ \overline x = \dfrac{947}{30} \approx 31.5 \overline 6[/tex]
[tex]s = \dfrac{x}{10 } - \dfrac{1}{10}[/tex]
[tex]E(s) = \dfrac{Ex}{10 } - \dfrac{1}{10}[/tex][tex]E(s) = \dfrac{31.5 \overline 6}{10 } - \dfrac{1}{10} = 3.05 \overline 6[/tex]
The mean ≈ 3.05[tex]\overline 6[/tex]Alternatively
,[tex]The \ mean \ of \ the \ daily \ total \ sunshine, \, s = \dfrac{31.5 \overline 6 - 1}{10 } = 3.05\overline 6[/tex]
The mean of the daily total sunshine, [tex]\overline s[/tex] ≈3.05[tex]\overline 6[/tex]
[tex]Var(s) = Var \left(\dfrac{x}{10 } - \dfrac{1}{10} \right)[/tex][tex]Var(s) = \left(\dfrac{1}{10}\right)^2 \times Var \left(x \right)[/tex]
Therefore;
[tex]Var(s) = \left(\dfrac{1}{10}\right)^2 \times 33,065.37 = 330,6537[/tex]
Therefore;
[tex]s = \sqrt{330.6537} \approx 18.184[/tex]The standard deviation, [tex]s_s[/tex] ≈ 18.184

There are a total of 448 students at Westover Middle school. A total of 3/8 of the students participate in after-school activities. Of those students, 1/3 do not get home until 7 pm. How many students participate in after-school activities and get home after 7 pm?
Answer:
56 students
Step-by-step explanation:
Given information:
• 448 students total
• [tex]\frac{3}{8}[/tex] of 448 participate in after-school activities
• [tex]\frac{1}{3}[/tex] of those [tex]\frac{3}{8}[/tex] get home after 7 pm
To find how many students is [tex]\frac{1}{3}[/tex] of those who participate in after-school activities, you first need to find the exact number of how many participate in after school activities:
The amount of students who participate in after-school activities is [tex]\frac{3}{8}[/tex] the total number of students. So, multiply 448 × [tex]\frac{3}{8}[/tex]:
448 × [tex]\frac{3}{8}[/tex] Multiply.
[tex]\frac{1344}{8}[/tex] Simplify into a whole number.
1344 ÷ 8 Divide.
168
[tex]\frac{3}{8}[/tex] of the total students is 168 students.
To find the amount of students that do not get home until after 7 pm, multiply 168 by [tex]\frac{1}{3}[/tex]:
168 × [tex]\frac{1}{3}[/tex] Multiply.
[tex]\frac{168}{3}[/tex] Simplify into a whole number.
168 ÷ 3 Divide.
56
The amount of students that participate in after-school activities and get home after 7 pm is 56 students.

D) Vivek is 30 years younger than his father. After 10 years their ages will be in the ratio 1:2. Find their present ages.
Answer:
I think Vivek is 20 and his father is 50
Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50
Answer:
Vivek:20 years
Father:50 years
Step-by-step explanation:
Since it is a age question, their difference do not change, so
2-1=1 (difference in ratio)
1u=30
Vivek now:30-10=20 years
Father: 30x2=60
60-10=50 years

what is the answer i need help
Answer:
Step-by-step explanation:
The general linear equation:
[tex]y = mx+b[/tex], m is slope, b is y-intercept
Plugging the points that satisfy the line:
[tex]3 = 9m + b[/tex]
[tex]-7=-7m+b[/tex]
Subtracting the equations from each other:
[tex]10 = 16m\\m= \frac{10}{16} = \frac{5}{8}\\[/tex]
Plugging m to any of the equations:
[tex]3= \frac{45}{8} + b \\b=-2.625\\[/tex]
Therefore, the equation is:
[tex]y=0.625x-2.625[/tex]
Of the 258 million tons of waste generated 27 percent was paper. How much paper was thrown away in million tons
Answer:
69,660,000/258,000,000
Step-by-step explanation:
If you do part/whole = %/100 and solve that:
100 can go into 258,000,000 2580000 times, and whatever you do on the bottom must be done on the top, and since 27 is the percentage, 27 x 2580000 = 69,660,000
making the answer 69,660,000/258,000,000
