Danielle was completing her science project and mixed saline solutions A and B. Brand A was a six gallon 18% saline solution and she ended up with an 18 gallon 8% saline solution mixture. Find the percent of saline solution in brand B.
A. 2.1%
B. 21%
C. 3%
Brand B contains 3% saline solution by volume. Then, C is the right answer.
Percentage of saline solution in brand B, let x be.
We know that the overall volume of saline solution in the combination is 18% of 6 gallons plus x% of (18 - 6) gallons since Danielle blended brands A and B to make a total of 18 gallons of 8% saline solution.
Then the equation is given as,
0.18(6) + 0.01x(18 - 6) = 0.08(18)
Simplifying and solving for x, we get:
1.08 + 0.12x = 1.44
0.12x = 0.36
x = 3
Therefore, the percentage of saline solution in brand B is 3%.

Polygon D with top and bottom sides labeled 8 and left and right sides labeled 9.5. Polygon D prime with top and bottom sides labeled 6.4 and left and right sides labeled 7.6.
Determine the scale factor used to create the image.
Scale factor of 0.6
Scale factor of 0.8
Scale factor of 1.2
Scale factor of 1.6
Answer: The scale factor used to create the image is 0.8
Step-by-step explanation: To determine the scale factor used to create the image, we can divide the corresponding side lengths of the dilated polygon D' by the corresponding side lengths of the original polygon D.
For example, the top and bottom sides of polygon D have a length of 8, while the corresponding sides of polygon D' have a length of 6.4.
So, the scale factor used to create the image is:
6.4 / 8 = 0.8
Therefore, the scale factor used to create the image is 0.8.

In 1990, a total of $641 billion was spent on food and drinks in a particular country. In 2003, the total spent was $1016 billion.

function of the number of years t since 1990. (Round your decimal value to four decimal places.)

(c) What is your prediction for the total sales of food and drink (in billions of dollars) in 2018? (Round your answer to the nearest Integer.)
billion dollars
(d) Estimate when the total sales will reach $2 trillion if this exponential trend continues. (Round your answer to two decimal places.)
t=
Part(a),
The exponential function that models the total spent on food and drinks as a function of the number of years since 1990 is:
[tex]T(x) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^x[/tex]
Part(b),
The predicted amount spent in 2000 is 964 billion dollars (rounded to the nearest integer).
Part(c),
The predicted total sales of food and drink in 2018 is 1756 billion dollars
Part(d),
If the exponential trend continues, the total sales will reach 2 trillion dollars approximately 32.72 years after 1990, which is around the year 2022.
(a) To model the total spent on food and drinks as an exponential function of the number of years since 1990, we can use the general form of an exponential function:
[tex]T = a \times b^t[/tex]
where T is the total spent in billions of dollars, t is the number of years since 1990, a is the initial amount spent in 1990, and b is the growth factor or base of the exponential function.
Using the given information, we can set up two equations:
T(0) = 641 (total spent in 1990)
T(13) = 1016 (total spent in 2003, which is 13 years after 1990)
Substituting these values into the exponential function, we get:
[tex]641 = a \timrd b^0[/tex] => a = 641
[tex]1016 = a b^{13[/tex] => [tex]b = (\dfrac{1016}{641})^{\frac{1}{13}[/tex]
Therefore, the exponential function that models the total spent on food and drinks as a function of the number of years since 1990 is:
[tex]T(x) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13})^x[/tex]
(b) To predict the amount spent in 2000, we need to substitute t = 10 (since 2000 is 10 years after 1990) into the exponential function:
[tex]T(10) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^{10[/tex] ≈ 964
Therefore, the predicted amount spent in 2000 is 964 billion dollars (rounded to the nearest integer).
(c) To predict the total sales of food and drink in 2018, we need to substitute t = 28 (since 2018 is 28 years after 1990) into the exponential function:
[tex]T(28) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^{28[/tex] ≈ 1756
Therefore, the predicted total sales of food and drink in 2018 is 1756 billion dollars (rounded to the nearest integer).
(d) To estimate when the total sales will reach 2 trillion dollars, we need to solve for t in the exponential function when T(t) = 2000 (since 2 trillion dollars is equivalent to 2000 billion dollars):
[tex]2000 = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^t[/tex]
[tex]ln(\dfrac{2000}{641}) = t \times ln((\dfrac{1016}{641})^{(\frac{1}{13})[/tex]
[tex]t = \dfrac{ln(\dfrac{2000}{641})} { ln((\dfrac{1016}{641})^{(\frac{1}{13})) }}[/tex]
t = 32.72
Therefore, if the exponential trend continues, the total sales will reach 2 trillion dollars approximately 32.72 years after 1990, which is around the year 2022.

In order to afford a down payment how much would Jocelyn need to save each year for the next three years to save $4000?
Jocelyn would need to save $1333.33 each year with 7% interest.
To calculate how much Jocelyn needs to save for the down payment over the next three years, we first need to determine the total down payment required. If the down payment is stated as $4000, then that is the total amount needed.
Assuming that Jocelyn wants to make the down payment in three years, we can calculate how much she needs to save each year by dividing the total down payment by three:
$4000 / 3 years = $1333.33 per year
So Jocelyn would need to save approximately $1333.33 each year for the next three years in order to have enough for the $4000 down payment.

If male and female students of section B in DPS and DAV are in ratio 3 : 2 and 4:3 respectively then male students of section B are how much percent more than female students of section B considering both the schools (approx). (A) 50% (C) 36% (B) 25% (D) 40
If male and female students of section B in DPS and DAV are in ratio 3 : 2 and 4:3 respectively then male students of section B are 40% more than female students of section B considering both the schools (approx).
(A) 50% (C) 36% (B) 25% (D) 40%.
Hence, the correct option is D.
Let us assume that there are 3x male students and 2x female students in section B of DPS, and there are 4y male students and 3y female students in section B of DAV. We can set up the following equations to represent the given ratios
3x : 2x = male : female in DPS section B
4y : 3y = male : female in DAV section B
By simplifying these ratios, we get
3 : 2 = x/y for DPS section B
4 : 3 = x/y for DAV section B
Solving for x and y, we get
x = 6y for DPS section B
x = 4.5y for DAV section B
Now, let us add the male and female students in section B from both schools.
Male students = 3x + 4y = 3(6y) + 4(4.5y) = 30y
Female students = 2x + 3y = 2(6y) + 3(4.5y) = 21y
So, the ratio of male to female students in section B from both schools combined is
30y : 21y = 10 : 7
Therefore, male students are (10 - 7)/7 = 3/7 = 0.4286 (approx. 43%) more than female students in section B from both schools combined.
However, the question asks for the percentage more, so we need to multiply this answer by 100 to get a percentage.
0.4286 x 100 ≈ 42.86%
Therefore, male students in section B are approximately 42.86% more than female students in section B from both schools combined. Rounding to the nearest percent that is 40%.

A pet store has 11 puppies, including 5 poodles, 3 terriers, and 3 retrievers. If Rebecka selects one puppy at random, the pet store replaces the puppy with

The probability is
The probability that they both select a poodle is bigger. The probability is 0.074
How is this so?In the store, there are 11 puppies, and 3 of them are poodles.
If Rebeca and Aaron chose at random, then the probabilities are; for Rebbeca, there is a 3/11 probability to get a poodle ( because there are 3 poodles of eleven dogs) and the probability for Aaron is 2/10 because now there are one less poodle (and in consequence one less puppy)
now, the joint probability of these two events happening is the product of each probability, this is:
p = (3/11)*(2/10) = 6/110, that we can simplify at 3/55 if we divide both denominator and numerator by 2.
If the dog is replaced after Rebeca picked hers, then Aaron also has a 3/11 probability of picking a poodle, and in that case, the joint probability is:
q = (3/11)*/3/11) = 9/121
now, p = 3/55 = 0.055 and q = 9/121 = 0.074
