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

Step-by-step explanation:

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 )

Q4.
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

javier went to cvs to buy bags of candy for his friends for halloween. he bought three more bags of reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of reese's cost $5.50 each and bags of starburst cost $4.25 each. He spend a total of $48.50 and was not charged any tax. How many bags of lollipops did javier bought?
The number of bags bought by Javier will be 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Javier bought three more bags of Reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of Reese's cost $5.50 each, and bags of starburst cost $4.25 each. He spends a total of $48.50.
From the equations and solve them to get the number of lollypops.
R = L+3
L = S - 2
The equation for total cost will be,
3.75L + 5.5R + 4.25S = 48.5
3.75( s - 2) + 5.5( S + 1) + 4.25S
3.75S - 7.5 + 5.50S + 5.5 + 4.25 S = 48.5
13.5S = 48.5 + 2
13.5S = 50.2
S = 4
The number of lollypops will be,
L = S - 2
L = 4 - 2
L = 2
Therefore, the number of bags bought by Javier will be 2.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $28 monthly fee and charges an additional
50.08 for each minute of calls. The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls. For how many minutes of calls
w the costs of the two plans be equal?
Answer:
180 minutesStep-by-step explanation:
Let x be the number of minutes of calls.
The first plan has a $28 monthly fee and charges an additional $0.08 for each minute of calls:
p(f) = 0.08x + 28The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls:
p(s) = 0.13x + 19When p(f) = p(s) we get the following equation for x:
0.08x + 28 = 0.13x + 190.13x - 0.08x = 28 - 190.05x = 9x = 9/0.05x = 180The figures are similar. Find each missing measure.

There are 30 tickets numbered as 1, 2, 3, 4, 30 respectively. One random. What is the probability that the number on the ticket is a multiple 2 or 3
Answer:
2/3 or 66.66%Step-by-step explanation:
Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.
We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and therefore counted twice.
So we subtract 5 to get:
15 + 10 - 5 = 20 numbersIf we chose one ticket at random the probability is:
P(2x or 3x) = 20/30 = 2/3 or 66.66%Helpppp PLZZZZZZZZZZZZ and thank you
