Answer:
The first one is x=3y-5
The second one is y/2 + 3
Step-by-step explanation:
For the first one you have to switch sides
X-3=3y-8
X - 3=3y-8
Then you add three to both sides
X-3+3=3y-8+3
Then simplify
X=3y-5
For the second one
you switch sides then add 5 to both sides then simplify
2x-5+5=y+1+5
Y/2 +3 or
Y+6 /2

how many years after the 1972 ban did it take for ddt levels to move from a rapid to slower rate of decline
Answers
According to all Reports of U.S media and other,
approx. 97 years after in 1972 ban did it take for ddt levels to move from a rapid to slower rate of decline.
DDT (dichloro-diphenyl-trichloroethane) has been one of the most commonly used pesticide chemicals in the United States for many years and was first synthesized in 1874. However, its efficacy as an insecticide was not discovered until 1939. Shortly thereafter, especially during World War I, the United States began producing large amounts of DDT abroad to combat vector-borne diseases such as typhoid fever and malaria. It declined sharply, falling from a peak of about $80m that year to just under $12m in the early 1970s. Over 80% of the amount of pesticides used between 1970 and 1972 was on cotton, with the rest mainly on peanuts and soybeans. The decline in DDT use is due to
(1) increased resistance to insects
(2) development of more effective alternative pesticides
(3) Growing public concern about adverse environmental impacts.
(4) Strengthening government restrictions on the use of DDT.
Residues of the pesticide DDT in the food supply, human tissues, and the environment have declined in recent years, especially since the EPA banned the chemical from major uses in 1972.

In the standard normal distribution, where X ~ N(0, 1), what proportion of the area is greater than 1
Answers
In the standard normal distribution, approximately 15.87% of the area is greater than 1.
In the standard normal distribution, where X follows a normal distribution with a mean of 0 and a standard deviation of 1 (X ~ N(0, 1)), we can determine the proportion of the area that is greater than a specific value using the z-score.
To find the proportion of the area greater than 1, we need to calculate the cumulative probability to the right of 1.
This involves finding the z-score corresponding to 1 and then using a standard normal distribution table or a calculator to determine the proportion.
The z-score represents the number of standard deviations a particular value is from the mean.
In this case, to find the z-score for 1, we subtract the mean (0) from 1 and divide by the standard deviation (1), giving us a z-score of 1.
Using a standard normal distribution table or a calculator, we can find the proportion of the area to the right of 1 by looking up the z-score of 1.
The corresponding value in the table or calculator represents the proportion of the area to the left of that z-score.
Since we want the proportion to the right of 1, we subtract the value obtained from 1.
In this case, the proportion of the area greater than 1 in the standard normal distribution is approximately 0.1587 or 15.87%.

Answers
The number of basketballs and soccer balls that there are in the bag are;
Soccer balls = 10
Basketballs = 53
How to solve Algebra Word Problems?We are told that Joseph has a bag of balls for the students to play with. The bag has 5 times as many basketballs as soccer balls in the bag.
Let basketballs be b
Let soccer balls be s.
Thus;
b = 5s
Total number of balls is 63 balls. Thus;
5s + s = 63
6s = 63
s = 63/6
s = 10.5
b = 5(10.5)
b = 52.5

John goes to a restaurant and has a bill of $ 32. 57. He uses a 10% off coupon on the cost of his meal. The tax is 8%. He leaves a tip of 18% on the amount before the coupon or tax is applied. How much does he spend?
Answers
Answer: $36.97
Step-by-step explanation:
The cost of the meal was $32.57 and he used a 10% off coupon. You can make 10% equal to 0.1 because \(\frac{10}{100}=0.1\). Now do \(0.1 *32.57=$3.26\). This is the discount, so you want to subtract this from the original to get the actual price of the meal, \(32.57-3.26=29.31dollars\).
The tax was 8% so this means he is adding it to his total cost instead of subtracting it. Do 0.08 of $29.31 to get $2.34. Add $2.34 to the now $29.31 to get $31.69.
The tip is also adding to the total cost, so do 0.18 of $29.31 to get $5.28. Add $5.28 to $31.69 to get $36.97
Answer:
$37.51
Step-by-step explanation:
Original cost of meal is $32.57.
Since he has a coupon for 10% off, he pays for 90% of the cost of the meal.
90% of $32.57 = 0.9 * $32.57 = $29.31
Now he pays tax on the new discounted total. Let the new total be called 100%. Since he pays 8% tax, he needs to pay 108% of the new total.
108% of $29.31 = 1.08 * $29.31 = $31.65
He adds a tip of 18% of $32.57.
The tip amount is
18% of $32.57 = 0.18 * $32.57 = $5.86
The total is: $31.65 + $5.86 = $37.51

Heron's formula makes use of s, which is described as the semi-perimeter of the triangle. Before we can use Heron's formula, let us solve first for the value of s via the equation
\(s=\frac{1}{2}(a+b+c)\)The lengths of the triangle are given in the problem. Just plug it in on the equation above and compute.
\(s=\frac{1}{2}(4+3+6)=\frac{13}{2}\)Now, let's move on using Heron's formula to solve the area of the triangle. We have
\(\begin{gathered} A=\sqrt[]{s(s-a)(s-b)(s-c)} \\ A=\sqrt[\square]{\frac{13}{2}(\frac{13}{2}-4)(\frac{13}{2}-3)(\frac{13}{2}-6)_{}} \\ A=\sqrt[]{\frac{13}{2}\lbrack(\frac{5}{2}\times\frac{7}{2}\times\frac{1}{2})\rbrack} \\ A=\sqrt[]{\frac{13}{2}(\frac{35}{8})} \\ A=\sqrt[]{\frac{455}{16}}=5.33 \end{gathered}\)Therefore, the area of the triangle is 5.3 square units.

suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. if the temperature on the ground is 56.9°F, what will be the temperature when the plane reaches an altitude of 8,000 ft?
Answers
We have a linear model, that relates temperature with altitude.
The first senctence gives us a clue about tha rate of change (the slope) of temperature in function of the altitude.
We can write the slope, in °F/1000 ft, as:
\(m=-1.2\)The temperature on the ground, where h=0, is 56.9 °F, so we can write the equation of the line as:
\(T(h)=-1.2h+56.9\)When the altitude is 8,000 ft, h=8 and T is:
\(T(8)=-1.2\cdot8+56.9=-9.6+56.9=47.3\)The temperature at 8,000 ft will be 47.3 °F.

In the second step, the student did not use the quotient of powers property correctly. Instead, they should have subtracted inside the parentheses instead of dividing. This would have left them with \(x^{(\frac{4}{5} )}\). They should have then multiplied this power by \(^{\frac{1}{2} }\) resulting in \(x^{(\frac{4}{10})}\) which simplified is \(x^{(\frac{2}{5}) }\) which is the correct answer.

• Lisa chooses a bead randomly from the bag.
Answers
The probability of choosing a specific color of bead is B. 2/3. Since there are an equal number of each color, this is also the probability of choosing any of the colors.
Bead Color Probability in BagIf there are an equal number of orange, green, and blue beads in Lisa's bag, and the total number of beads is 30, then each color has 30/3 = 10 beads.
Therefore, if Lisa chooses a bead randomly from the bag, each color has an equal chance of being selected, and the probability of choosing an orange, green, or blue bead is 2/3.
The probability of choosing a specific color of bead can be determined by counting the number of favorable outcomes (the number of beads of the chosen color) and dividing it by the total number of possible outcomes (the total number of beads in the bag).
In this case, there are 10 beads of each color, so the number of favorable outcomes for each color is 10. The total number of beads in the bag is 30, so the total number of possible outcomes is 30.
