Hyun Yong wants to donate more than $5000 in laptops and bicycles. Each laptop that he donates is worth $200, and each bicycle that he donates is worth $100. Write an inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.
Answer:
$200L+$100B ≥$5000
Step-by-step explanation:
Given :
Hyun Yong wants to donate more than $5000 in laptops and bicycles.
Each laptop that he donates is worth $200, and each bicycle that he donates is worth $100.
To Find : An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.
Solution :
L denotes the number of laptops.
Since cost of each laptop is $200
Thus cost of L laptops = $200L
B denotes the number of bicycles.
Since cost of each bicycle is $100.
Thus cost of B bicycles = $100B
Now, he wants to donate more than $5000 in laptops and bicycles
So, inequality will be : $200L+$100B ≥$5000
Hence, An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal:
$200L+$100B ≥$5000
which is of the numbers is composite? 41,77,83,89,97
Answer:
77 is a composite number
Step-by-step explanation:
41 = 1 × 41
77 = 1 × 77 = 7 × 11
83 = 1 × 83
89 = 1 × 89
97 = 1 × 97
Answer:
Step-by-step explanation:I would say 77.The reason is because a composite number is where it has a multiple more than just itself or 1.So what you can do is write the multiples of each number.Then once you do that you can easily tell which numbers are composite and prime numbers.Remember prime numbers are numbers that just have a multiple of one and itself.

Each day, Karen makes 45 loaves of bread at the bakery where she works. Each loaf of bread requires 5 cups of flour. One pound of flour is equivalent to about 4 cups of flour. About how many pounds of flour does Karen need in order to make the loaves of bread?
Answer: 5cups of flour = 1 loaf of bread
45 loaves of bread multiplied by 5 cups of four = 225 cups of flour to make 45 loaves of bread.
225 cups of flour divided by 4 = 56.25 pounds of flour.
Karen needs approximately 56.25 pounds of flour to make the loaves of bread.
Explanation:To find how many pounds of flour Karen needs to make the loaves of bread, we need to convert the number of cups into pounds. Each loaf requires 5 cups of flour, and 1 pound of flour is equivalent to about 4 cups. Therefore, we can set up a proportion to find the number of pounds:
pounds of flour / cups of flour = number of loaves
Let's solve for pounds of flour:
pounds of flour = (number of loaves * cups of flour per loaf) / cups of flour per pound
Plugging in the numbers, we get:
pounds of flour = (45 * 5) / 4 = 56.25 pounds
Therefore, Karen needs approximately 56.25 pounds of flour to make the loaves of bread.

I currently have 4 wild bunnies running around my yard. They are freaking annoying. Especially because they are doubling in number every month. Assuming this continues how many bunnies will be annoying me in 2 years.
Answer:
y = 67108864 rabbits
Step-by-step explanation:
The equation for growth is
y= a(b)^(t)
where a is the initial amount
b is the growth rate and
t is the time in months
2 years = 24 months
Assuming the population doubles at the end of the 1st month
Substituting in what we know
y = 4 (2) ^ (t)
y= 4 *2 ^ 24
y = 4*16777216
y = 67108864 rabbits
If they do not double at the end of the first month and wait until the second month, divide this number by 2
y = 4 (2) ^ (t-1)
y= 4 *2 ^ 23
y = 4*8388608
y = 33554432 rabbits

Answer:
g=4
Step-by-step explanation:
If you're solving for g, you need to get it alone on one side. The way I did so was to subtract 7 from each side.
15 = 2g + 7
-7 -7
If you do that, the 7 on the right cancels out and you're left with 8 = 2g. To get the g alone, you divide it by it's base on both sides which in this case is 2.
8/2 = 2g/2
That will cancel the 2 out and will leave you with g on the right side and on the left side would be 4 because simple division (8/2=4)
Your final answer should be g = 4

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
of the students are left-handed.
of the students are right-handed.
A comparison of these two fractions is:
Final answer:
In a classroom with 12% left-handed students, the fraction representing them is 3/25 after simplification, and with 88% right-handed students, their fraction is 22/25. Since 22/25 is greater than 3/25, there are more right-handed students.
Explanation:
If 12% of the students in your class are left-handed, the fraction of students that are left-handed is 12/100, which can be simplified to 3/25 by dividing both the numerator and the denominator by 4. There are clearly more right-handed students because if 12% are left-handed, then 100% - 12% = 88% are right-handed. The fraction of right-handed students is 88/100, which simplifies to 22/25. Comparing the two fractions, 3/25 for left-handed students and 22/25 for right-handed students, it’s evident that there are more right-handed students in your class.

Help with recursive Arithmetic sequence
Answer:
Slope is 5, y-int is 1, and f(n) = 5n+1
Step-by-step explanation:
So, since we are dealing with an arithmetic sequence, it is linear. If you notice, it is just adding 5 from the previous term. This represents a slope of 5. Increase of 1 in x and increase of 5 in y. Then, f(1) = 6. Since 1 x 5 is 5, and 5 + 1 = 6, the b is 1. This is because the normal 5x is deviated by 1. Since it is arithmetic, that 1 unit deviation will carry on. The last question basically says just write the y=mx + b but just use n and f(n), which is f(n) = 5n + 1.
If K is the midpoint of jl ,jk =9x-1 and kl =2x+27, find jl
Answer:
JL = 70
Step-by-step explanation:
If K is the midpoint of the segment, then JK = KL
JK = KL
9x-1 = 2x+27
Subtract 2x from each side
9x-2x -1 = 2x+27-2x
7x-1 = 27
Add 1 to each side
7x-1+1 = 27+1
7x = 28
Divide each side by 7
7x/7 = 28/7
x =4
But we want to find JL
JL = JK + KL
JL = 9x-1 +2x+27
Combine like terms
JL = 11 x+ 26
Substitute x =4
JL = 11*4+26
JL = 44+26
JL = 70
The length of line segment JL, when K is its midpoint and given jk = 9x - 41 and kl = 2x + 27, is 70.
Explanation:This question is related to geometry and specifically the section on line segments. Firstly, if K is the midpoint of line segment JL, that means JK and KL are of equal lengths. So, we can set their equations equal to each other:
9x - 1 = 2x + 27
To solve this equation, start by subtracting 2x from both sides to isolate the variable x on one side:
7x - 1 = 27
Next, add 1 to both sides:
7x = 28
Dividing both sides by 7 gives:
x = 4
Substitute x = 4 into either of the equations, say kl = 2x + 27, gives the length of segment KL as:
kl = 2(4) + 27 = 35
The length of JL would then be twice the length of KL (since K is the midpoint) so:
jl = 2 * 35 = 70.

A basketball player has made 80% of his foul shots during the season. Assuming the shots are independent, find the probability that in tonight's game he does the following. a) Misses for the first time on his fourth fourth attempt b) Makes his first basket on his fourth fourth shot c) Makes his first basket on one of his first 3 shots
a) The probability of missing for the first time on the fourth attempt is 0.16%. b) The probability of making the first basket on the fourth shot is 0.8%. c) The probability of making the first basket on one of the first 3 shots is 99.2%.
Explanation:a) To find the probability that the basketball player misses for the first time on his fourth attempt, we need to consider that each shot is independent. Since he has made 80% of his shots, the probability of making a shot is 0.8. Therefore, the probability of missing a shot is 1 - 0.8 = 0.2. Since the shots are independent, the probability of missing on the fourth attempt is 0.2 raised to the power of 4 = 0.0016, or 0.16%.
b) To find the probability that the basketball player makes his first basket on his fourth shot, we use a similar approach. The probability of making a shot is 0.8, and the probability of missing a shot is 0.2. The probability of making a shot on the fourth attempt is then 0.2 raised to the power of 3, multiplied by 0.8 = 0.2 * 0.2 * 0.2 * 0.8 = 0.008, or 0.8%.
c) To find the probability that the basketball player makes his first basket on one of his first 3 shots, we need to find the complementary probability. The probability of not making a basket on the first 3 shots is 0.2 raised to the power of 3 = 0.008. Therefore, the probability of making a basket on one of the first 3 shots is 1 - 0.008 = 0.992, or 99.2%.
