Ryan went into town and bought some chicken feed that would last for the next 60 days. If he buys two 50 lbs bags for 5 chickens, how much does each chicken eat a day.
Answers
Answer:
3 pounds
Step-by-step explanation:
1. 50 + 50 = 100
2. 100 / 5 = 20
3. 60 / 20 = 3
Each chicken eats approximately 0.3333 pounds of feed per day, which is calculated by dividing the total feed (100 lbs) by the number of days (60) and then by the number of chickens (5).
To calculate how much chicken feed each chicken eats a day, we need to start by understanding the total amount of feed Ryan bought. He bought two 50 lbs bags, which is a total of 100 lbs of chicken feed. Since the feed needs to last 60 days for 5 chickens, we will divide the total feed by the number of days and then by the number of chickens.
First, we convert the weight of the feed into pounds (if it is not already in pounds). We know there are 100 lbs of feed in total.
Next, we divide the total weight of the feed by the number of days to find out how much feed is used per day:
100 lbs / 60 days = 1.6667 lbs per day (for all 5 chickens together).
Finally, we divide the daily feed consumption by the number of chickens to find out how much each chicken eats per day:
1.6667 lbs per day / 5 chickens = 0.3333 lbs per chicken per day.
Therefore, each chicken eats approximately 0.3333 pounds of feed a day.
Find the measures of the numbered angles in the kite? (image below please help)
Answers
answer
1, 2, 3, 4 = 90 degrees
5 = 41 degrees
6 = 39 degrees
7, 9 = 51 degrees
8, 10 = 49 degrees
step-by-step explanation
since this is a kite, the lengths p and q (the diagonals of the kite) are perpendicular to each other, so angles 1, 2, 3, and 4 are all 90 degrees
to find angle 5, we know that the kite is symmetric across the horizontal diagonal, so angle 5 would be the same as 41 degrees
to find angle 6, we also look at symmetry, so angle 6 is the same of 39 degrees
to find angle 7, all three angles in a triangle, bottom left, must add up to 180. since we know angle 3 = 90 and angle 6 = 39, angle 7 = 180 - 90 - 39 = 51 degrees
because of symmetry, angle 9 would be equal to angle 7 = 51 degrees
to find angle 8, all three angles in a triangle, bottom right, must add up to 180. since we know angle 4 = 90 and angle 5 = 41, angle 8 = 180 - 90 - 41 = 49
because of symmetry, angle 10 would be equal to angle 8 = 49

Final answer:
Using the order of operations, first calculate the value within the parentheses, perform the division, then proceed with the addition, and finally subtract to find that the solution to the expression 8+24 ÷ (2×6) - 4 is 6.
Explanation:
To address the problem 8+24 ÷ (2×6) - 4, the correct application of the order of operations, known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is required.
First, handle the expressions inside the parentheses:
Calculate the value within the parentheses: (2×6) equals 12.Perform the division: 24 ÷ 12 equals 2.Proceed with the addition: 8 + 2 equals 10.Finally, subtract 4 from the result: 10 - 4 equals 6.Therefore, the final answer to the expression is 6.
Assume that y varies inversely with x. If y= 16 when x = 0.5, find y when x = 32.
y=[ ? ]
Answers
The constant of variation k for the inverse variation is found to be 8. When x = 32 is substituted into the formula y * x = k, we find that y = 0.25.
Explanation:In problems where y varies inversely with x, it means that their product is constant. This can be represented as y * x = k, where k is the constant of variation. Given that y = 16 when x = 0.5, we can find the constant by plugging these values into the formula. Hence, 16 * 0.5 = k, so k = 8.
Now to find y when x = 32, we substitute these values into the formula. We know that y * 32 = 8, so y = 8 / 32. This simplifies to y = 0.25.

A female dust mite is 0.42 millimeter long. How do u write this measurement in scientific notation
Answers
Final answer:
The length of the female dust mite, 0.42 millimeters, is written in scientific notation as 4.2 × 10[tex]10^{-1}[/tex]millimeters.
Explanation:
To write the measurement of a female dust mite, which is 0.42 millimeter long, in scientific notation, we first identify the most significant digit and the decimal point. In scientific notation, numbers are typically written in the form of a single digit from 1 to 9, followed by a decimal point and the remaining significant digits, and then multiplied by 10 raised to the appropriate exponent.
The number 0.42 can be written as 4.2 times 10 to the power of negative one (because the decimal point has been moved one place to the right to place it after the first non-zero digit, 4).
So, in scientific notation, the length of a female dust mite is 4.2 × [tex]10^{-1}[/tex] millimeters.
You paid $600 for a new guitar. Your guitar costs $40 more than twice the cost of your friend's guitar. How much did your friend's guitar cost?
Answers
Cost of your guitar = $ 600
Let your friend's guitar's cost be = n
According to the question =
Your guitar costs $ 40 more than twice the cost of your friend's guitar which is n ,but your guitar's cost is $ 600.
So ,the linear equation for this will be =
= 2n+$40 = $600
= 2n = $600-$40
= 2n = $ 560
= n = $ 560/2
= n = $ 280
Thus ,the cost of your friend's guitar is $ 280.The cost of your friend's guitar is $280 by creating an equation based on the cost comparison to your own guitar, and then solving for the variable representing your friend's guitar's cost.
You paid $600 for a new guitar, which costs $40 more than twice the cost of your friend's guitar. To find the cost of your friend's guitar, let's denote the cost of your friend's guitar as x. According to the information given, your guitar's cost can be represented by the equation 2x + $40 = $600. Solving for x will give us the following steps:
Subtract $40 from both sides of the equation: 2x = $600 - $40.
This simplifies to 2x = $560.
Divide both sides by 2: x = $560 / 2.
Therefore, x equals $280.
The cost of your friend's guitar is $280.

12x-5y=-20
y=x+4
x=_______
y=_______
Answers
Answer:
x = 0
y = 4
Step-by-step explanation:
Given
12x - 5y = -20
y = x + 4
Substitute x + 4 for y in the first equation
12x - 5(x + 4) = -20
Expand the bracket
12x -5 X x - 5 x 4 = -20
12x - 5x - 20 = -20
7x - 20 = -20
Add 20 to both sides to eliminate -20 on the left side
7x - 20 + 20 = -20 + 20
7x = 0
Divide both sides by 7 to isolate x
7x/7 = 0/7
x = 0
Substitute 0 for x in either equation to get y
Using equation 2, we have
y = x + 4
= 0 + 4
= 4
x = 0
y = 4

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?
Answers
Answer:
1/7
Step-by-step explanation:
i learned this arealdy
The probability of drawing at least one red marble from a bag containing 3 blue and 5 red marbles in two draws without replacement is 19/28.
To find the probability of drawing at least one red marble from a bag with 3 blue and 5 red marbles, with one draw already taken, we calculate the probability of not drawing a red marble and subtract that from 1. Since there are more red than blue marbles, the probability of drawing a red one on the first draw is higher. However, the problem states that the marbles are not replaced after drawing, so the probabilities change with every draw.
There are two ways to not draw a red marble in two draws:
First draw: blue, Second draw: blue.
First draw: red, Second draw: blue.
Let's calculate these probabilities. For the first case, there's a 3/8 chance of drawing blue first, and then 2/7 chance of drawing blue again, since one blue marble has been removed, which equals to 3/8 * 2/7 = 6/56 or 3/28. For the second case, there is a 5/8 chance of drawing red first, and then a 3/7 chance of drawing blue, equalling 5/8 * 3/7 = 15/56. The sum of these probabilities is 3/28 + 15/56 = 9/28.
Therefore, to find the probability of at least one red, we subtract the summed probabilities from 1: 1 - 9/28 = 19/28.
Thus, the probability of drawing at least one red marble is 19/28.
