Answer:
Step-by-step explanation:
Let x be the adult weight of a puppy A
25% of x = 8 pounds
[tex]\frac{25}{100}*x=8\\\\ x=\frac{8*100}{25}\\\\ =8*4=32pounds\\[/tex]
Final answer:
To calculate the adult weight of Puppy A, divide the current weight of 8 pounds by 0.25 since 8 pounds is 25% of the adult weight. The adult weight of Puppy A is 32 pounds.
Explanation:
The student is asking how to find the adult weight of Puppy A, given that its current weight is 25% of its adult weight. To solve this, we need to use the concept of percentages. If Puppy A currently weighs 8 pounds and this represents 25% of the adult weight, we can set up a proportion:
25% (current weight) / 100% (adult weight) = 8 pounds / adult weight
To find the adult weight, we divide 8 pounds by 25% (0.25 in decimal form):
Adult weight = 8 pounds / 0.25
Adult weight = 32 pounds
Therefore, the adult weight of Puppy A is expected to be 32 pounds.

what is 5/5/8 divided by 1/2/9 in simplest form
The division of 5/5/8 by 1/2/9 in simplest form is 405/88 after converting the mixed numbers to improper fractions, then multiplying by the reciprocal, and simplifying.
Explanation:To find the simplest form of the division of two mixed numbers, first, both mixed numbers must be converted to improper fractions. Dividing by a fraction is the same as multiplying by its reciprocal. So, when dividing 5/5/8 by 1/2/9, we first turn these into improper fractions.
5/5/8 becomes 45/8 (since 5*8+5=45) and 1/2/9 becomes 11/9 (since 1*9+2=11). Now the problem is 45/8 divided by 11/9. To divide these fractions, we multiply by the reciprocal: 45/8 * 9/11 = (45*9)/(8*11) = 405/88.
To simplify 405/88, we find the Greatest Common Divisor (GCD) of the numerator and the denominator, which is 1 in this case, so the fraction is already in its simplest form, which is 405/88.
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/2/9 is 9/2/1. So, the expression becomes 5/5/8 multiplied by 9/2/1. To multiply fractions, we multiply the numerators together and the denominators together. So, (5 x 9) / (5 x 2) x 8 / 1 = 45/10 x 8/1 = 360/10 = 36.

If gas costs $4 per gallon, how much will gas cost Sally per day just to get to and from Job A per day? per week? per year?
To find the cost of gas for Sally's commute, you would multiply the number of gallons she uses daily by the cost per gallon. Assuming a daily use of one gallon at $4 per gallon, Sally would spend $4 per day, $20 per week (5-day workweek), and $1,040 per year (52 workweeks). This does not account for variable factors such as days off or gas price changes.
Explanation:The student is asking about the cost of gasoline for commuting to and from a job. Since we do not have the exact distance Sally travels or the efficiency of her vehicle, we cannot compute the exact cost per day, week, or year. However, if we assume Sally uses one gallon of gas per day at a cost of $4 per gallon, here's how you calculate the costs:
Per day: Sally would spend $4 each day on gas.Per week: Assuming she works 5 days a week, Sally would spend 5 days x $4/day = $20 per week on gas.Per year: If Sally works 52 weeks a year, she would spend 52 weeks x $20/week = $1,040 per year on gas.These calculations are based on the premise of daily one-gallon gas usage and do not take into account vacations, days off, or possible fluctuations in gas prices.

If a=2b^3 and b= -1/2c ^-2,express a in terms of c.
Answer:
Part 1) [tex]a=-\frac{1}{4c^6}[/tex]
Part 2) [tex]a=-\frac{1}{4c^{-6}}[/tex]
Step-by-step explanation:
Part 1) we have
[tex]a=2b^{3}[/tex] ----> equation A
[tex]b=-\frac{1}{2}c^{-2}[/tex] ----> equation B
substitute equation B in equation A
[tex]a=2(-\frac{1}{2}c^{-2})^{3}[/tex]
Applying property of exponents
[tex](x^{m})^{n}=x^{m*n}[/tex]
[tex]x^{-m} =\frac{1}{x^{m}}[/tex]
[tex]a=2(-\frac{1}{2}c^{-2})^{3}=2(-\frac{1}{2})^3(c^{-2})^{3}=2(-\frac{1}{8})(c^{-6})=-\frac{1}{4c^6}[/tex]
therefore
[tex]a=-\frac{1}{4c^6}[/tex]
Part 2) we have
[tex]a=2b^{3}[/tex] ----> equation A
[tex]b=-\frac{1}{2c^{-2}}=-\frac{c^{2}}{2}[/tex] ----> equation B
substitute equation B in equation A
[tex]a=2(-\frac{c^{2}}{2})^{3}[/tex]
Applying property of exponents
[tex](x^{m})^{n}=x^{m*n}[/tex]
[tex]x^{-m} =\frac{1}{x^{m}}[/tex]
[tex]a=2(-\frac{c^{2}}{2})^{3}=2(-\frac{c^{6}}{8})[/tex]
simplify
[tex]a=-\frac{c^{6}}{4}[/tex]
therefore
[tex]a=-\frac{1}{4c^{-6}}[/tex]
Q(9,10) . R(-5,2) . S(-8,-2) . T (-1,2) . Parallel or Perpendicular
Answer:
Perpendicular
Step-by-step explanation:
Put all the points on a graph.
Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.
On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
Rewrite 3/4x+2=9/10 so that it doesn’t have fractions
The equation with no fractions is:
30x + 80 = 36
Solution:
Given that the equation is:
[tex]\frac{3}{4}x+2=\frac{9}{10}[/tex]
We have to rewrite the equation such that there is no fraction
From given expression,
[tex]\frac{3}{4}x+2=\frac{9}{10}[/tex]
Simplify the left hand side of equation
[tex]\frac{3x+8}{4} = \frac{9}{10}[/tex]
Cross multiply to get a simpler equation
[tex]10(3x+8) = 9 \times 4\\\\Simplify\ the\ above\ expression\\\\30x + 80 = 36[/tex]
Thus the equation is rewritten with no fractions
To rewrite the equation 3/4x + 2 = 9/10 without fractions, we multiply every term by the lowest common denominator (20) to get 15x + 40 = 18. Then, we isolate x by subtracting 40 from both sides to get 15x = -22. We solve for x by dividing both sides by 15, resulting in x = -22/15.
Explanation:The aim is to rewrite the equation 3/4x + 2 = 9/10 without fractions. To get rid of the fractions, we'll multiply each term by the lowest common denominator (LCD). In this case, the LCD is 20 because it's the smallest number both 4 and 10 can both go into. The equation thus becomes: 20*(3/4x) + 20*2 = 20*(9/10)
This simplifies to: 15x + 40 = 18
Now, to isolate x, we start by subtracting 40 from both sides:
15x + 40 - 40 = 18 - 40
So, 15x = -22. Finally, to solve for x, we divide by 15:
x = -22/15

The speed of a boat in still water (b) is 50km/h. It takes the same time (t) for the boat to travel 10km (x) upstream as it does to travel 20km (y) downstream. Find the speed of the current.
upstream speed (u) = speed in still water (b) - stream speed (s) = b-s = 50-s
downstream speed (d) = speed in still water (b) + stream speed (s) = 50+s
time (t) = x/u = y/d
10/(50-s) = 20/(50+s)
10(50+s) = 20(50-s)
500 + 10s = 1000 - 20s

Common difference = [tex]\frac{1}{5}[/tex]
Solution:
Given arithmetic sequence:
[tex]$-2,-1\frac{4}{5} ,-1\frac{3}{5} , -1\frac{2}{5} , ....[/tex]
Let us first convert the improper fraction into mixed fraction.
[tex]$-2,-\frac{9}{5} ,-\frac{8}{5} , -\frac{7}{5} , ....[/tex]
Difference between two numbers in an arithmetic sequence is the common difference.
[tex]$a_2-a_1=-\frac{9}{5}-(-2)=-\frac{9}{5}+2=\frac{1}{5}[/tex]
[tex]$a_3-a_2=-\frac{8}{5}-\left(-\frac{9}{5}\right)=-\frac{8}{5}+\frac{9}{5}=\frac{1}{5}[/tex]
[tex]$a_4-a_3=-\frac{7}{5}-\left(-\frac{8}{5}\right)=-\frac{7}{5}+\frac{8}{5}=\frac{1}{5}[/tex]
Common difference = [tex]\frac{1}{5}[/tex].
Hence the common difference of the arithmetic sequence is [tex]\frac{1}{5}[/tex].
Common difference of the given arithmetic sequence is equal to [tex]\frac{1}{5}[/tex]
Explanation:The given arithmetic sequence is in mixed numbers. Converting them into proper fractions, we get:
[tex]First\ term = t_1 = -2\\\\Second\ term = t_2 = -1\frac{4}{5} = -\frac{(5\times1)+4}{5} = -\frac{9}{5}\\\\Third\ term = t_3 = -1\frac{3}{5} = -\frac{(5\times1)+3}{5} = -\frac{8}{5}\\\\Fourth\ term=t_4 = -1\frac{2}{5} = -\frac{(5\times1)+2}{5} = -\frac{7}{5}[/tex]
The sequence can thus be rewritten as [tex]-2, -\frac{9}{5}, -\frac{8}{5}, -\frac{7}{5}[/tex]
To find the common difference of the given arithmetic sequence, subtract any two consecutive numbers of the sequence. The difference between two consecutive numbers is always a constant and is termed as the common difference.
Hence,
[tex]d_1= t_2-t_1=(-\frac{9}{5} -(-2)= \frac{-9+10}{5}= \frac{1}{5} \\\\d_2=t_3-t_2= (-\frac{8}{5} -(-\frac{9}{5} )= \frac{-8+9}{5} = \frac{1}{5}\\\\d_3=t_4-t_3= (-\frac{7}{5} -(-\frac{8}{5} )= \frac{-7+8}{5} = \frac{1}{5}[/tex]
[tex]d_1=d_2=d_3 = d[/tex]

Julie is 6 feet tall. If she stands 15 feet from the flagpole and holds a cardboard square, the edges of the square line up with the top and bottom of the flagpole. Approximate the height of the flagpole
Answer:
43.5 ft
Step-by-step explanation:
Given: Julie is 6 feet tall
She stands 15 feet from the flagpole.
The edges of the square line up with the top and bottom of the flagpole.
Picture drawn to show side and angle formed by Julie and flagpole.
Lets assume the height of flagpole be "h".
As given, the edges of the square line up with the top and bottom of the flagpole.
∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.
Now, finding the height of flagpole by using tangent rule.
we know, [tex]tan\theta= \frac{Opposite}{adjacent}[/tex]
Remember, both the angle are equal.
∴ Ratio of opposite and adjacent leg for both right angle triangle= [tex]\frac{6}{15} : \frac{h-6}{15}[/tex]
We can put it; [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]
Solving the equation now
⇒ [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]
Multiplying both side by 15
⇒[tex]6 = \frac{15\times 15}{h-6}[/tex]
Multiplying both side by (h-6)
⇒ [tex]6\times (h-6) = 15\times 15[/tex]
Distributive property of multiplication
⇒ [tex]6h-36= 225[/tex]
Adding both side by 36
⇒[tex]6h= 225+36[/tex]
Dividing both side by 6
⇒[tex]h= \frac{261}{6}[/tex]
∴ [tex]h= 43.5\ feet[/tex]
Hence, the height of flagpole is 43.5 feet.
The height of the flagpole is given by the length of the hypotenuse side
formed by the right triangle Julie forms with the cardboard.
Response:
Height of the flagpole is 17.4 feetWhich method is used to calculate the height of the flagpole?The triangle formed by the edges of square lined up with the top and
bottom of the flagpole is a right triangle.
The altitude of the right triangle formed with the height of the flagpole as the base = 15 feet
Length of a leg of the right triangle = √(15² + 6²) = 3·√(29)
The other angle formed by the right triangle = (90° - arctan(15/6))
h × sin(arctan(15/6)) = 3·√29
[tex]h = \mathbf{\dfrac{3 \cdot \sqrt{29} }{sin(arctan(15/6))} } = 17.4[/tex]

What is the probability of getting a head followed by a 6?
[tex]\frac{?}{?}[/tex]
Answer:[tex]\frac{1}{12}[/tex]
Step-by-step explanation:
Okay, first, you want to find the probability of getting a head, which would be 1/2 because there are two options and we are only looking for one out of the two. Then, the probability of getting a 6 would be 1/6 because there is only one chance of getting a 6 and there are 6 options. Next, you would have to multiply both quantities to find out what the probability would be of getting both. So it would be [tex]\frac{1}{2}[/tex] ×[tex]\frac{1}{6}[/tex]=[tex]\frac{1}{12}[/tex]
Probability of getting a head followed by a 6 is 1/12
Step-by-step explanation:
There are 2 possible outcomes of tossing a coin a head and a tail.
The probability is 1 out of 2 each for head and tail.
Probability of getting a 6 when a dice is rolled is 1 out of 6 for each face i.e 1,2,3,4,5,6
So the probability of getting a head followed by 6 is 1/2*1/6 = 1/12
It can also be understood as below.
There can be 12 possible combinations once a coin is tossed and a die is rolled. Head-1, Head-2. Head-3, Head-4, Head-5, Head-6, Tail-1, Tail-2, Tail-3, Tail-4, Tail-5, Tail-6
In the list there is 1 outcome that we need. Head-6. This again gives us the chance of getting Head-6 as 1 out of 12.

The inverse relation of [tex]\( y = 3x + 12 \)[/tex] is [tex]\( x = \frac{y - 12}{3} \)[/tex].
To find the inverse of the relation [tex]\( y = 3x + 12 \)[/tex], we start by expressing it in terms of [tex]\( x \)[/tex] and [tex]\( y \)[/tex]:
[tex]\[ y = 3x + 12 \][/tex]
Next, solve for [tex]\( x \)[/tex]:
[tex]\[ y - 12 = 3x \][/tex]
[tex]\[ x = \frac{y - 12}{3} \][/tex]
Thus, the inverse relation is:
[tex]\[ x = \frac{y - 12}{3} \][/tex]
To verify, substitute [tex]\( x \)[/tex] with [tex]\( \frac{y - 12}{3} \)[/tex] back into the original equation:
[tex]\[ y = 3 \left( \frac{y - 12}{3} \right) + 12 \][/tex]
