Answer:
38.5 minutes or if rounded up it would be 39 minutes.
Step-by-step explanation:
22 divided by 4 bags would get you 5.5. This means it would take you 5.5 minutes to rake 1 bag. Since, they already raked 4 bags that would be 22 minutes, plus the other 3 bags it would be, 5.5 x 3 = 16.5 minutes. Add it together and you get 22 minutes + 16.5 minutes = 38.5 minutes to rake 7 bags. Hope this helped!

name the property of real numbers illustrated by each equation
The property of real numbers illustrated by each equation depends on the specific equation. However, some common properties of real numbers include the commutative property, associative property, distributive property, identity property, and inverse property.
The property of real numbers illustrated by each equation depends on the specific equation. However, there are several properties of real numbers that can be applied to equations:
commutative property: This property states that the order of addition or multiplication does not affect the result. For example, a + b = b + a and a * b = b * a.associative property: This property states that the grouping of numbers in addition or multiplication does not affect the result. For example, (a + b) + c = a + (b + c) and (a * b) * c = a * (b * c).distributive property: This property states that multiplication distributes over addition. For example, a * (b + c) = (a * b) + (a * c).identity property: This property states that there exist unique elements called identity elements for addition and multiplication. For addition, the identity element is 0, and for multiplication, the identity element is 1. For example, a + 0 = a and a * 1 = a.inverse property: This property states that every real number has an additive inverse and a multiplicative inverse. The additive inverse of a number a is -a, and the multiplicative inverse of a non-zero number a is 1/a. For example, a + (-a) = 0 and a * (1/a) = 1.Learn more:About property of real numbers here:

the probability that a student likes math is 0.7 and the probability that a student likes history is 0.2 . if only 10% of students like both math and history, what is the probability that a student chosen at random dislikes at least one of them?
The probability that a student chosen at random dislikes at least one of them is 0.2. Probability is the likelihood of occurrence of an event.
Probability a student likes math's = 0.7
Probability a student dislikes maths = 1 - 0.7 = 0.3
Probability a student likes history = 0.2
Probability a student dislikes history = 1 - 0.2= 0.8
Probability a student likes maths and history = 0.1
Probability a student dislikes maths = 1 - 0.1= 0.9
Probability a student dislikes at least one of them = probability he dislikes math's + Probability a student dislikes history- Probability a student dislikes math's and history = 0.3+0.8-0.9 = 0.2

what conditions on (positive) numbers a,b,c, and d will guarantee that every difference at every step in the expansion (a-b)(c-d) results in a positive number?
The conditions on the positive numbers a, b, c, and d that will guarantee that every difference at every step in the expansion (a-b)(c-d) results in a positive number are:
1. a > b
2. c > d
This will ensure that the difference between a and b, as well as the difference between c and d, are both positive numbers. Therefore, when these two differences are multiplied together in the expansion (a-b)(c-d), the result will be a positive number.
For example, if a=5, b=2, c=8, and d=3, then the expansion (a-b)(c-d) will result in a positive number:
(5-2)(8-3) = (3)(5) = 15
As long as the conditions a > b and c > d are met, the expansion (a-b)(c-d) will result in a positive number.

sec^2 θ(1 - sin^2θ) = 1 To verify the identity, start wil more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at teach step.
sec^2 θ (1 - sin^2θ) = sec^2θ ______
= sec^2θ ______
= 1
irst, let's simplify the left side of the equation using trigonometric identities. We have sec^2θ(1 - sin^2θ).
Using the Pythagorean identity, sin^2θ + cos^2θ = 1, we can rewrite sec^2θ as 1/cos^2θ. Substituting this into the expression, we get (1/cos^2θ)(1 - sin^2θ). Next, we distribute the numerator (1) across both terms, giving us (1 - sin^2θ) / cos^2θ. Now, we recognize that (1 - sin^2θ) can be rewritten as cos^2θ using the Pythagorean identity again. Thus, the left side simplifies to cos^2θ / cos^2θ, which is equal to 1. Therefore, the left side is equivalent to the right side, verifying the given identity. We start by simplifying the left side of the equation using trigonometric identities. After applying the Pythagorean identity twice and simplifying, we arrive at the expression cos^2θ / cos^2θ, which is equal to 1. Hence, the left side is equivalent to the right side, verifying the identity.

Container a was filled with water to the brim. then, some of the water was poured into an empty container b until the height of the water in both containers was the same. find the new height in both water containers
After pouring some water from container A into container B, the new height of the water in both containers will be equal.
When container A is filled with water to the brim, it reaches its maximum capacity. Let's assume the initial height of the water in container A is h.
When some water is poured from container A into container B, the water level in both containers will gradually equalize until they reach the same height. Let's denote this new height as H.
The reason the water levels equalize is due to the principle of fluid equilibrium. When the containers are connected and the water is allowed to flow, the water seeks a common level. This occurs because the pressure at the same height in a fluid is equal.
Therefore, after pouring water from container A to container B, the final height of the water in both containers will be H, which indicates that the water has reached an equilibrium point where the pressure is equal in both containers.

the smith family has cats and dogs. in how many ways can these pets be placed in a row of chairs such that at least cats are next to each other?
The number of ways to arrange the pets such that at least one pair of cats are next to each other is:
(n+m)!/(n!m!) - (m+n-1)!/(m!(n-1)!). Considering n as catcats and m as dogs
There are a few different ways to approach this problem, but one possible method is to use the complement principle, which states that the total number of ways to arrange the pets minus the number of ways to arrange them such that no cats are next to each other will give the number of ways to arrange them such that at least one pair of cats are next to each other.
Let n be the number of cats and m be the number of dogs. The total number of ways to arrange the pets in a row of chairs is (n+m)!/(n!m!), which is the number of ways to arrange n identical cats and m identical dogs. To arrange the pets such that no cats are next to each other, we can first arrange the cats in n! ways and then place the dogs between the cats in (m+n-1)!/(m!(n-1)!) ways, since there are m+n-1 spaces to place the m dogs and n-1 dividers between the n cats.
Therefore, the number of ways to arrange the pets such that at least one pair of cats are next to each other is:
(n+m)!/(n!m!) - (m+n-1)!/(m!(n-1)!)

left on together, the cold and hot water faucets of a certain bathtub take minutes to fill the tub. if it takes the hot water faucet minutes to fill the tub by itself, how long will it take the cold water faucet to fill the tub on its own?
The cold water faucet will fill the tub on its own in 5.6 minutes.
Let us assume the time taken by cold water faucet to fill the tub be x minutes. Now, the rate of hot water faucet to fill the tub = 1/14
Combined rate of filling by both faucets = 1/4
Rate of filling by hot water faucet + Rate of filling by cold water faucet = Rate of filling of tub by combination of two faucets
1/14 + 1/x = 1/4
1/x = 1/4 - 1/14
1/x = (14 - 4)/(4×14)

8x -x+5y units
what’s the perimeter?
Answer:
P = 16x+26y units
Step-by-step explanation:
Let the length is (x+8y) units
Width = (8x-x+5y) units
We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.
P = 2[(x+8y) + (8x-x+5y)]
= 2[(8x+8y+5y)]
= 2[8x+13y]
= 16x+26y
Hence, the required perimeter is 16x+26y.
12.0-ev electron encounters a barrier of height 15.0 ev. if the probability of the electron tunneling through the barrier is 2.5 %, find its width.
The width of the barrier is 1.53×10⁻¹⁴ m
How to find the width of the barrier?The probability of an electron tunneling through a barrier is given by the equation:
P = (2m/h²) × (E²) × (exp(-2a/h))
where P is the probability of tunneling, m is the mass of the electron, h is Planck's constant, E is the energy of the electron, and a is the width of the barrier.
m = 9.109×10⁻³¹ kg, h = 6.626×10⁻³⁴m² kg/s
Substituting the values given in the problem, we have:
P = (2m/h²) × (E²) × (exp(-2a/h))
2.5% = (2× 9.109×10⁻³¹ / (6.626×10⁻³⁴)) × (12.0)² × (exp(-2a/( 6.626×10⁻³⁴)))
We can rearrange this equation to solve for the width of the barrier:
a = -(h/2) × ln(P/(E²× (2m/h²)))
= -(6.626×10⁻³⁴/2) ×ln(0.025 / (12.0 eV)² × (2×9.109×10⁻³¹ / (6.626×10⁻³⁴)²))

There are 354 mangoes. They have to be made into trays of 9 mangoes each. How many trays can be made? How many mangoes are left behind?
There are 3 mangoes left behind after making 39 trays of 9 mangoes each
To find out how many trays can be made from 354 mangoes, we divide the total number of mangoes by the number of mangoes per tray.
Number of mangoes per tray = 9
Number of trays = 354 mangoes / 9 mangoes per tray
Number of trays = 39 trays
So, 39 trays can be made from 354 mangoes.
To determine how many mangoes are left behind, we subtract the number of mangoes used for the trays from the total number of mangoes.
Number of mangoes left behind = Total number of mangoes - Number of mangoes used for trays
Number of mangoes left behind = 354 mangoes - (39 trays * 9 mangoes per tray)
Number of mangoes left behind = 354 mangoes - 351 mangoes
Number of mangoes left behind = 3 mangoes
Therefore, there are 3 mangoes left behind after making 39 trays of 9 mangoes each
