PLEASE IVE DONE THIS 3 TIMES EASY MATH CHALLENGE NEED EXPLANATION 20 POINTS The board game Kings crown has, red, green, and gold gems for the players to earn as they play. The game has 1/3 as many green games as red gems. It has 1/6 as many red gems as gold gems. What fraction of the game's gems are gold?
Answer:
9/11
Step-by-step explanation:
The green gems are red gems divided by three. The red gems are gold gems divided by six. Make the number of gold gems, g. The red gems would be g/6, and the green gems (g/6)/2=g/18. So, the total marbles would be g+g/6+g/18=18g/18+3g/18+g/18=22g/18=11g/9. Now you have to find what percent of 11g/9 is g. (11g/9)(percent)=g. The percent as a fraction is 9/11.
Bill Lutes's dog is on a strict diet. The dog is to receive, among other nutrients, 3232 grams of protein and 5.65.6 grams of carbohydrates. Bill has only two food mixes available of the following compositions. How many grams of each mix should be used to obtain the right diet for his dog?
Answer:
80g of A and 40g of B must be mixed.
Step-by-step explanation:
The mixes are:
Mix Protein (%) Carbohydrate (%)
Mix A 30 6
Mix B 20 2
The following equations can be formed using the provided data:
0.30A + 0.20B = 32...(i)
0.06A + 0.02B = 5.6...(ii)
Multiply (ii) by 5 and subtract the resultant equation from (i):
0.30A + 0.20B = 32
-0.30A - 0.10B = -28
0.10B = 4
B = 40
Substitute B in (i) and solve for A as follows:
0.30A + (0.20 × 40) = 32
0.30A = 32 - 8
0.30A = 24
A = 80
Thus, 80g of A and 40g of B must be mixed.
Using a system of equations, the number of grams of each mix required to make the right diet would be ; Mix A and B are 80 and 40 grams respectively.
For protein :
0.3a + 0.2b = 32 ------------(1)
0.06a + 0.02b = 5.6 - - - (2)
Multiply (1) by 1 and (2) by (5)
0.3a + 0.2b = 32 --------(3)
0.3a + 0.1b = 28 - - - - - (4)
Subtract (4) from (3)
0.1b = 4
b = 40
From (1) :
0.30a + (0.20)40 = 32
0.30a = 32 - 8
0.30a = 24
a = 80
Hence, the required grams of Mix A and B are 80 and 40 grams respectively.

to convert from percent to fraction:
70% = \(\frac{70}{100} =\frac{7}{10}\)
to convert from fraction to percent:
\(\frac{11}{20}=\frac{55}{100}\) = 55%
to convert from fraction to decimal:
\(\frac{3}{25} =\frac{12}{100} =0.12\)
to convert from decimal to fraction:
\(1.25=\frac{125}{100} =1\frac{25}{100} =1\frac{1}{4}\)

What two numbers multiply to -35 and add to get -18
he two numbers that multiply to -35 and add to get -18 are -5 and 3.
To see why, you can use the factoring method. First, find two numbers that multiply to give you -35. The factors of -35 are -1, 1, -5, and 5. So, the two numbers that multiply to -35 are either -5 and 7 or 5 and -7.
Next, find which pair of numbers adds up to -18. It's clear that 5 and -7 add up to -2, so they don't work. However, if we choose -5 and 3, we get:
-5 + 3 = -2
So, -5 and 3 are the two numbers that multiply to -35 and add to -18.

6. Rewrite y = √√4x+16 +5 to make it easy to graph using a translation. Describe the graph.
Answer:
~
Step-by-step explanation:
To make it easier to graph using a translation, we can rewrite the given equation as:
y - 5 = √√4x + 16
This is obtained by subtracting 5 from both sides of the equation.
The graph of the original equation y = √√4x+16 +5 can be obtained by taking the graph of y = √√4x + 16 and shifting it upwards by 5 units. The graph of y = √√4x + 16 is a square root function that has a vertical stretch of 2, a horizontal compression of 4, and a vertical translation of 16 units upwards. So the graph of the given equation y = √√4x+16 +5 will be the same as the graph of y = √√4x + 16, but shifted upwards by 5 units.
Consider the differential equation: 2y′′−13y′−7y = 0
a. Show that, for any constants A and B, the following is a solution to the above differential equation: y = Ae^(−9x)+Be^(x/3)
b. Find the values A and B that make the above general solution into a solution for the following initial value problem: 2y′′−13y′−7y = 0; y(0) = 3, y′(0) = −5
--------------------------------------------------
Just a correction, the characteristic roots of the equation are \(y = 7\) and \(y = -\frac{1}{2}\), thus, we should test for:
\(y = Ae^{7x} + Be^{-\frac{x}{2}}\)
--------------------------------------------------
Question a:
First, we find the derivatives, thus:\(y = Ae^{7x} + Be^{-\frac{x}{2}}\)
\(y^{\prime} = 7Ae^{-7x} - \frac{1}{2}Be^{-\frac{x}{2}}\)
\(y^{\prime\prime} = 49Ae^{-7x} + \frac{1}{4}Be^{-\frac{x}{2}}\)
Now, we replace into the equation:\(2y^{\prime\prime} - 13y^{\prime} - 7y = 0\)
\(2(49Ae^{-7x} + \frac{1}{4}Be^{-\frac{x}{2}}) - 13(7Ae^{-7x} - \frac{1}{2}Be^{-\frac{x}{2}}) - 7(Ae^{7x} + Be^{-\frac{x}{2}}) = 0\)
\(98Ae^{-7x} + \frac{1}{2}Be^{\frac{x}{2}} - 91Ae^{-7x} + \frac{13}{2}e^{-\frac{x}{2}} - 7Ae^{7x} - 7Be^{-\frac{x}{2}} = 0\)
\(98Ae^{-7x} - 91Ae^{-7x} - 7Be^{-\frac{x}{2}} + \frac{1}{2}Be^{\frac{x}{2}} + \frac{13}{2}e^{-\frac{x}{2}} - 7Be^{-\frac{x}{2}} = 0\)
\(0A + 0B = 0\)
\(0 = 0\), thus, we found the identity, and for each constant A and B, the following is a solution.
--------------------------------------------------
Question b:
\(y = Ae^{7x} + Be^{-\frac{x}{2}}\)
Since \(y(0) = 3\)\(A + B = 3 \rightarrow B = 3 - A\)
--------------------------------------------------
\(y^{\prime} = 7Ae^{-7x} - \frac{1}{2}Be^{-\frac{x}{2}}\)
Since \(y^{\prime}(0) = -5\)\(7A - \frac{1}{2}B = -5\)
Using \(B = 3 - A\)
\(7A - \frac{3}{2} + \frac{A}{2} = -5\)
\(\frac{14A}{2} + \frac{A}{2} = -\frac{10}{2} + \frac{3}{2}\)
\(\frac{15A}{2} = -\frac{7}{2}\)
\(15A = -7\)
\(A = -\frac{7}{15}\)
--------------------------------------------------
Then, B is given by:
\(B = 3 - A = 3 - (-\frac{7}{15}) = \frac{45}{15} + \frac{7}{15} = \frac{52}{15}\)
Thus, the values are: \(A = -\frac{7}{15}, B = \frac{52}{15}\)

. In a fort, there were provisions for 400 men for 23 weeks. 60 more men joined them. How long will the provisions
last?
The additional 60 men, the provisions will last for approximately 20 weeks.
To determine how long the provisions will last with the additional 60 men, we need to consider the total number of people and the original duration the provisions were meant to last.
Originally, the provisions were intended to sustain 400 men for 23 weeks. This means that the provisions were estimated to be sufficient for a total of 400 * 23 = 9200 person-weeks.
Now, with the additional 60 men, the total number of men becomes 400 + 60 = 460.
To calculate how long the provisions will last with the increased number of men, we divide the total person-weeks by the new number of men:
Provisions last = Total person-weeks / Number of men
= 9200 / 460
≈ 20 weeks (rounded to the nearest whole number)
The additional 60 men will extend the supply's shelf life to around 20 weeks.

Determine the largest power of 10 that is a factor of the following numbers (equivalently, the number of terminal 0's, using ordinary base 10 representation):(a) 50!.
(b) 1000!.
The largest power of 10 that is a factor of 1000! is 5^249, or 10^249.
(a) To find the largest power of 10 that is a factor of 50!, we need to count the number of factors of 5 in 50! since each factor of 5 contributes at least one factor of 10.
There are 10 multiples of 5 in 50!, namely 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50. Each of these contributes one factor of 5. There are also 2 multiples of 25 (25 and 50), each of which contributes an additional factor of 5. Therefore, the total number of factors of 5 in 50! is 10 + 2 = 12.
Since each factor of 10 contains one factor of 5 and one factor of 2, we also need to count the number of factors of 2. It is clear that there are more factors of 2 than factors of 5, so we only need to count the factors of 5. Therefore, the largest power of 10 that is a factor of 50! is 5^12, or 10^12.
(b) To find the largest power of 10 that is a factor of 1000!, we follow the same reasoning as in part (a). The number of factors of 5 in 1000! is:
⌊1000/5⌋ + ⌊1000/25⌋ + ⌊1000/125⌋ + ⌊1000/625⌋ = 200 + 40 + 8 + 1 = 249
