There are 8 hamsters at crazy Pete pet shop that are completely brown the rest of the hamsters at the shop are mixed colors that ate brown hamsters represent 2/5 of the total Number of hamsters at the pet shop right and solve an equation using the variable H to find the total number of hamsters at the pet shop
The farmer originally planted 15 apple trees.
Let's denote the original number of rows as [tex]\( r \)[/tex] and the original number of columns as [tex]\( c \).[/tex]
In the original arrangement, the total number of trees is [tex]\( r \times c \).[/tex]
If 5 more rows and 3 fewer columns are added, the new number of rows becomes [tex]\( r + 5 \)[/tex] and the new number of columns becomes [tex]\( c - 3 \).[/tex]
According to the given information, the new arrangement has 25 more trees than the original arrangement. So, we can set up the equation:
[tex]\[ (r + 5) \times (c - 3) = r \times c + 25 \][/tex]
Expanding the left side:
[tex]\[ r \times c + 5r - 3c - 15 = r \times c + 25 \][/tex]
Now, let's simplify:
[tex]\[ 5r - 3c - 15 = 25 \][/tex]
[tex]\[ 5r - 3c = 40 \][/tex]
Now, let's solve this equation to find the relationship between [tex]\( r \)[/tex] and [tex]\( c \).[/tex]
Given the information, let's make some assumptions about the number of rows and columns to fit the situation realistically.
Let's start with 1 row and 3 columns ( [tex]\( r = 1, c = 3 \)[/tex] ):
[tex]\[ 5(1) - 3(3) = 5 - 9 = -4 \][/tex]
It doesn't satisfy the condition.
Next, let's try 2 rows and 4 columns ( [tex]\( r = 2, c = 4 \)[/tex] ):
[tex]\[ 5(2) - 3(4) = 10 - 12 = -2 \][/tex]
Still doesn't satisfy the condition.
Next, let's try 3 rows and 5 columns ( [tex]\( r = 3, c = 5 \)[/tex] ):
[tex]\[ 5(3) - 3(5) = 15 - 15 = 0 \][/tex]
This satisfies the condition.
So, the original arrangement had 3 rows and 5 columns, and the total number of trees is [tex]\( 3 \times 5 = 15 \)[/tex].
Solve P=hr(1-d) for d

If the test scores of a class of 36 students have a mean of 75.2 and the test scores of another class of 28 students have a mean of 67.4, then the mean of the combined group is
The mean of the combined group is 71.78.
What is arithmetic mean?Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations.
Let the total sum of the scores of the first class of 36 students be ∑x.
Here, the mean is 75.2 .
⇒ ∑x/36 = 75.2
⇒ ∑x = (75.2)(36)
⇒ ∑x = 2707.2
Also, let the total sum of the scores of the second class of 28 students be ∑y.
Here, the mean is 67.4.
⇒ ∑y/28 = 67.4
⇒ ∑y = (67.4)(28)
⇒ ∑y = 1887.2
The total students in combined group = 36+28 =64
The sum of their scores = ∑x + ∑y = 2707.2 + 1887.2 = 4594.4
The mean of the combined group = (∑x + ∑y)/64
The mean of the combined group = 4594.4/64 = 71.78

The rocks near the shore between two lighthouses at points A and B make the waters unsafe. The measure of arcAXB is 300. Waters inside this arc are unsafe. Suppose you are a navigator on a ship at sea. How can you use the lighthouses to keep the ship in safe waters?
A ship's navigator can keep the ship in safe waters by staying outside the 300-degree arc between two lighthouses and using the beams as navigational guides. Additionally, in areas with water breaks, navigators should account for wave diffraction to determine the safest angles for mooring.
Explanation:To navigate safely and avoid the unsafe waters near the coastline marked by the 300-degree arc between two lighthouses at points A and B, a ship's navigator should use both lighthouses as reference points for establishing a safe navigational path. Typically, lighthouses are equipped with rotating beams, which can serve as a guide to determine a ship's position relative to hazardous areas. If the ship maintains a course outside of the direct line of sight between the two lighthouses, it can stay within the safe waters.
The navigator should also consider wave action when near a coastline or harbor entrance. If any breakwater structure or water break exists, such as a rock barrier with an opening, the navigator would need to be mindful of the wave patterns. As waves enter the opening, they diffract, and boats are generally safest at angles where the wave intensity is minimized.

Which pair of expressions is equivalent for any variable value greater than zero?
Answer:
D. b+b+3c and 2b+3c
Step-by-step explanation:
The question wants us to find out expressions is equivalent for any variable value greater than zero. So let's analyse all the possible answers to find the correct one.
A. (x+3) and 3x+ 2
If x = 1 , we have:
(x+3) = 4 3x+2 = 5Both of the two sides are not equivalent
B. 4d+2e and 8d+e
If e=1 and d=1, we have:
4d+2e = 88d+e = 9Both of the two sides are not equivalent
C. f+f+f+g and 3fg
If f=1 and g=1, we have:
f+f+f+g = 43fg = 3Both of the two sides are not equivalent
D. b+b+3c and 2b+3c
If b=1 and c=1, we have:
b+b+3c = 52b+3c = 5Both of the two sides are equivalent
Or we will simplify the left side: b+b+3c = 2b+3c, hence 2b+3c = 2b+3c are apparent
So we choose D.

If a, b, c, and d are four different numbers and the proportion a/b = c/d is true, which of the following is false?
In the proportion a/b = c/d, if this is true then the product of the extremes (a*d) is equal to the product of the means (b*c). Any statement that contradicts this property is considered false.
Explanation:Looking at the given condition, a/b = c/d, it represents a proportion or a statement of equality between two fractions. Within this proportion, `a` and `d` are referred to as the extremes, while `b` and `c` are known as the means.
If the proportion is true, meaning it accurately reflects a relationship of equality between two ratios, several properties become applicable. Importantly, the product of the means equals the product of the extremes. In other words, in a valid proportion, `a*d` is equal to `b*c`.
Consequently, if any statement contradicts these properties, it is false. So, without knowing the specific statements to analyze here, we cannot accurately decide on the false one. Always remember, you need to comply with the stated properties of a proportion in mathematical contexts.

The perimeter of a rectangular garden is 102 meters. the length is 6 meters longer than twice the width. find the dimensions of the garden.
Final answer:
The width of the garden is 15 meters and the length is 36 meters.
Explanation:
To solve this problem, we can use the formulas for perimeter and length. Let's assume that the width of the rectangular garden is x.
According to the given information, the length is 6 meters longer than twice the width, so the length can be represented as 2x + 6.
The perimeter is the sum of all four sides of the rectangle, which is given as 102 meters. We can set up the equation:
2(2x + 6) + 2x = 102
Simplifying the equation, we get:
6x + 12 = 102
6x = 90
x = 15
Therefore, the width of the garden is 15 meters and the length is 2(15) + 6 = 36 meters.

A clown needed 275 balloons for a party he was going to, but the balloons only came in packs of 2.How many packs of balloons does he need to buy?
Final answer:
To provide 275 balloons when they are sold in packs of 2, the clown will need to purchase 138 packs, which will include one extra balloon as you cannot buy half a pack.
Explanation:
The clown needs 275 balloons for a party and they come in packs of 2. To find out how many packs of balloons the clown needs to buy, one must divide the total number of balloons by the number in each pack.
The calculation is as follows:
Number of packs = Total balloons ÷ Balloons per packNumber of packs = 275 ÷ 2Number of packs = 137.5Since packs cannot be purchased in halves, the clown will need to buy 138 packs to have enough balloons, understanding that this means having one extra balloon.
