Answer:
y = -2x+28
Step-by-step explanation:
We have the slope and a point, so we can use the point slope form to make a line
y-y1 = m(x-x1)
y-12 = -2(x-8)
Distribute the -2
y-12 = -2x+16
Add 12 to each side
y-12+12 = -2x+16+12
y = -2x+28
This is the slope intercept form of the line
I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?
Answer:
Basically, you have to think: more bricks : more time
more workers : less time
2,400 bricks 6 workers takes 18 hours
You now have to solve for 4,500 blocks and 10 workers
4,500 / 2,400 = 1.875 (times greater)
10 / 6 = 1.666666666 (times less)
So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666
which equals 20.25 hours

Step-by-step explanation:
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%.

The regular price of a jacket is $200. Today, the jacket is on sale. It is 20% off its regular price. The sales tax is 8%. If Steven buys the jacket today, how much will he pay?
Answer:
$172.80
Step-by-step explanation:
200*20%=40
200-40=160
160*0.08=12.8
12.8+160=172.80
Answer:
He pays $176
Step-by-step explanation:
First, to find 80% of 200, we can simply multiply 200 by .8.
200 x .8=160
Then, we add sales tax to that number. To find 8% of 200, multiply 200 by .08.
200 x .08=16
Then, add 16 to 160.
160+16= 176
Your answer is $176.

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.

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

1. Correct. The reflection happens over segment AB and then you translate 6 units to the right and 3 units up. This will move point A to D, B to F, C to E, to have the triangles line up perfectly.
-----------------------------------------------
2. Problem 1 already confirmed the triangles are congruent based on how they line up perfectly. Another way to prove this is to either use the SAS (side angle side) or LL (leg leg) theorem. With SAS, we need a pair of congruent sides and a pair of angles, with the angles between the two sides. The horizontal and vertical sides can be easily measured. The angles between the two sides are 90 degree angles. Because we have right triangles, we can use LL which is really just a special case of SAS.
-----------------------------------------------
3. Segment EF is 5 units. You can use the pythagorean theorem with a = 3 and b = 4 to solve a^2+b^2 = c^2 to get c = 5. Or you can use the fact that BC = 5 is given to us, so EF must also be 5 as well. This is because of the idea that if two triangles are congruent, then their corresponding pieces must be the same as well.
Real world example: imagine having 2 houses that are perfect clones of each other. If this is the case, then surely their front doors would be identical copies as well. In this analogy, a house is a triangle, while the front door is the segment.

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

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.
