The amount of time they rest in 8 hours is 40 minutes.

Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.

In the problem, it is stated that a couple rests for 25 minutes in 5 hours during a dance-a-thon. We can use this information to find out how long they rest each hour. To do this, we simply divide the total amount of time they rest (25 minutes) by the number of hours (5 hours). That is:

rest time in 1 hour = 25 minutes / 5 hours = 5 minutes.

So, if they dance for 8 hours, the amount of time they rest will be:

8 hours * 5 minutes/hour = 40 minutes.

Step-by-step explanation:

Answer: a. The area of the rectangular base of the bale of hay is 2 feet * 3 feet = 6 square feet.

The area of the circular base of the bucket is π * (diameter/2)^2, where the diameter is 3 feet, so the area is π * (3/2)^2 = π * (9/4) = 9π/4 square feet.

Since π is approximately equal to 3.14, the area of the circular base is approximately 9 * 3.14 / 4 = 6.935 square feet, which is less than the area of the rectangular base.

So the rectangular base of the bale of hay is larger in area.

b. The volume of the bale of hay is 2 feet * 3 feet * 5 feet = 30 cubic feet.

The volume of the bucket is π * (diameter/2)^2 * height, where the diameter is 3 feet and the height is 5 feet, so the volume is π * (3/2)^2 * 5 = π * (9/4) * 5 = 45π/4 cubic feet.

Since π is approximately equal to 3.14, the volume of the bucket is approximately 45 * 3.14 / 4 = 34.65 cubic feet, which is less than the volume of the bale of hay.

So the bale of hay is larger in volume.

Additional comment

A set of integers that satisfies the Pythagorean theorem is called a "Pythagorean triple." Perhaps the first one you run across is {3, 4, 5}. Other triples commonly seen are {5, 12, 13}, and {7, 24, 25}. This one, {8, 15, 17} also shows up in algebra and trig problems. It can be worthwhile to remember a few of these.

Their multiples are also seen. For example, {6, 8, 10} is the {3, 4, 5} triple times 2.

The probability that Sergio's number is larger than the sum of the two numbers chosen by Tina is 0.4

We can calculate the probability by finding the number of favorable outcomes, i.e., the number of ways that Sergio can choose a number that is larger than the sum of the two numbers chosen by Tina, and dividing it by the total number of possible outcomes, which is

5C2 * 10C1 = (5!/(2! * 3!)) * 10

Erika has 6.53 kilograms of apples, which is more than the 6 kilograms she needed for the recipe. Therefore, she has enough apples to make the recipe.

To determine if Erika has at least 6 kilograms of apples, we need to add the weight of all three bags of apples. The total weight of the apples is:

2.56 kg + 1.18 kg + 2.79 kg = 6.53 kg

Erika needs a certain amount of apples for a recipe, specifically 6 kilograms. She goes to the store and picks three different bags of apples - a 2.56-kilogram bag of red apples, a 1.18-kilogram bag of green apples, and a 2.79-kilogram bag of yellow apples. To determine if she has enough apples, she needs to add the weight of all three bags. The total weight of the apples comes out to be 6.53 kilograms. This means that Erika has more than the required 6 kilograms of apples and is sufficient to make the recipe. It's important to note that Erika has an excess of apples, which can be helpful in case she needs extra for the recipe or for future use.

A line must have a 2 1/2 slope in order to be perpendicular to the line whose equation is 6x + 15y = 225.

A line's slope is determined by its inclination.

M is used to signify it.

m = (y₂ - y1)/(x₂ -x₁).

Consider Point 1 and Point 2 as the two points on a line.

The coordinates for Point 1 are (x1,y1), while the coordinates for Point 2 are (x2,y2).

The line equation was provided to us as follows:

⇒ 6x + 15y = 225

⇒ 15y = -6x + 255

⇒ y = -6/15 x + 255/15

The slope, m = -6/15

The angle of perpendicularity = -1/m

⇒ -1/(-6/15)

Reciprocal the term of denominator, and we get    

⇒ 15/6  = 2 1/2

Therefore, a line must have a 2 1/2 slope in order to be perpendicular to the line whose equation is 6x + 15y = 225.

What is Reflection across a line?

It is discovered using reflections principles that:

1) When a function is reflected across the x-axis, the x-coordinates remain unchanged, however the y-coordinates have the opposite signal.

2) When a function is reflected across the y-axis, the y-coordinates remain unchanged, whereas the x-coordinates have the opposite signal.

Given that,

      Triangle is reflected across the dashed line with coordinates of P' if P(8, 5).

Reflection across a line means taking a shape and flipping it over the line so that it appears as its mirror image.

In the case of the point P(8,5), reflecting it across the dashed line would result in a new point P' whose y-coordinate is the opposite of the y-coordinate of P.

Therefore, P' would have coordinates (8, -5).

ΔGAS ≅ ΔIOLby AAS

Step-by-step explanation:

We can prove congruence by the AAS Theorem

AAS Theorem

By definition, AAS congruence rule states that if any two angles and the non-included side of one triangle are equal to the corresponding angles and the non-included side of the other triangle, the two triangles must be congruent

In triangles ΔGAS and ΔIOL

We have:
∠G ≅ ∠I
m∠A ≅ m∠O

AS ≅ OL

AS is the non-included side of ΔGAS and OL is the non-included side of ΔIOL

Therefore we have two corresponding angles congruent and the non-included side of each of these triangles also congruent

Therefore by the AAS (Angle-Angle-Side) theorem, the two triangles are congruent

ΔGAS ≅ ΔIOL by AAS

Answer:

ΔGAS ≅ ΔIOL by AAS

Step-by-step explanation:

From the dashes on the angles and sides of the given triangles:

Therefore, the two triangles have two corresponding congruent angles and a congruent corresponding non-included side.  This means we can show that the triangles are congruent by the AAS congruence Theorem.

If any two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.

The heaviest pack's maximum allowable weight is d = 46 - 39 = 7 kg.

Let the four packs each weight a, b, c, and d (with a <= b <= c <= d).

Using the given data, we can formulate the following six equations:

a + b = 34

a + c = 37

a + d = 39

b + c = 41

b + d = 43

c + d = 46

the fourth equation and the first equation added:

2a + 2b = 34 + 41 = 75

Solving for a, we get:

a = (75 - 2b) / 2

Substituting this into the first equation:

(75 - 2b) / 2 + b = 34

Multiplying both sides by 2:

75 - 2b + 2b = 68

Solving for b, we get:

b = 34 - (75 - 68) / 2 = 34 - 3.5 = 30.5

Substituting this value into the equation for a:

a = (75 - 2 * 30.5) / 2 = (75 - 61) / 2 = 7

The greatest possible weight of the heaviest pack is d = 46 - c. Since c <= 46 - a = 46 - 7 = 39,

The greatest possible weight of the heaviest pack is d = 46 - 39 = 7 kg.
