All 3 bags of grapes weighed 1,245 pounds.  Each bag weighed 415 pounds, so to find the total weight of all 3 bags, we need to multiply 415 by 3.

415 * 3 = 1,245

Therefore, all 3 bags of grapes weighed 1,245 pounds.

Sure! Let's break down the explanation in more detail:

Martin bought 3 bags of grapes, and each bag weighed 415 pounds. To find the total weight of all the bags, we need to multiply the weight of each bag by the number of bags.

Since each bag weighed 415 pounds, we can multiply this weight by 3 bags:

415 pounds × 3 bags = 1,245 pounds

It's important to note that we obtain this result by performing a basic multiplication operation. By multiplying the weight of each bag (415 pounds) by the number of bags (3), we can determine the combined weight accurately.

The sets A = (3, 4, 7, 9, 10) and B = (6, 8) do not have any common elements, indicating that they are disjoint sets.

Disjoint sets are sets that have no elements in common. In this case, we can compare the elements of set A = (3, 4, 7, 9, 10) with the elements of set B = (6, 8) to determine if they have any common elements. By comparing each element in set A with each element in set B, we find that there are no elements that appear in both sets.

Set A contains the elements 3, 4, 7, 9, and 10, while set B contains the elements 6 and 8. There is no overlap between these two sets, as none of the elements in set A match any of the elements in set B. Therefore, we can conclude that set A and set B are disjoint sets.

It's worth noting that disjoint sets are just one type of relationship between sets, and there are other types of relationships, such as subsets, supersets, and overlapping sets. However, in this specific case, the sets A and B do not share any common elements, indicating that they are disjoint.

To solve the equation [tex]-0.2 = |1 - 0.8x|[/tex], we need to consider two cases: one where the absolute value is positive and one where it is negative.

Case 1: [tex]1 - 0.8x \geq 0[/tex]

In this case, the absolute value is positive. We can rewrite the equation as[tex]-0.2 = 1 - 0.8x[/tex]. Solving for x, we subtract 1 from both sides and then divide by -0.8:

[tex]-0.2 - 1 = -0.8x[/tex]

[tex]-1.2 = -0.8x[/tex]

Dividing both sides by -0.8 gives x = 1.5.

Case 2: [tex]1 - 0.8x < 0[/tex]

In this case, the absolute value is negative. When the absolute value is negative, it becomes positive. We can rewrite the equation as [tex]-0.2 = -(1 - 0.8x)[/tex]. Removing the negative sign, we have [tex]-0.2 = -1 + 0.8x[/tex]. Solving for x, we add 1 to both sides and then divide by 0.8:

The new pressure of the nitrogen gas after it is transferred to a 15.0 L container is 833.3 mmHg.

We are given that;

Capacity of nitrogen gas= 25L

Pressure= 500mmHg

Now,

To find the new pressure of the nitrogen gas, we need to use Boyle’s law, which states that the product of pressure and volume of a gas is constant at constant temperature 12. The formula for Boyle’s law is:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume of the gas, and P2 and V2 are the final pressure and volume of the gas.

We are also given the final volume of the gas as 15.0 L. We need to find the final pressure of the gas.

Plugging in these values into the formula, we get:

(500.0 mmHg)(25.0 L) = P2(15.0 L)

Solving for P2, we get:

P2 = (500.0 mmHg)(25.0 L) / (15.0 L) P2 = 833.3 mmHg

Therefore, by algebra the answer will be 833.3 mmHg.

To find: [tex]$\angle BAD$.[/tex]

Solution:

Here is the figure that represents the given statements:

As we know that [tex]$BA || CE$[/tex],

so we can say that [tex]$\angle DAE$[/tex] and [tex]$\angle ECD$[/tex] are corresponding angles.

Thus, [tex]$\angle ECD = 52^\circ$.[/tex]

In [tex]$\triangle ACE$[/tex] , we have [tex]$\angle ACE + \angle ECD + \angle AEC = 180^\circ$[/tex].

As [tex]$CE || BA$, $\angle AEC = \angle BAD$[/tex]

So, we have [tex]$\angle ACE + \angle ECD + \angle BAD = 180^\circ$[/tex]

Putting values of [tex]$\angle ECD$ and $\angle ACE$[/tex] in the above equation,

we get

[tex]\begin{align*}\angle BAD + \angle ACB + 52^\circ &= 180^\circ \\ \Rightarrow \angle BAD &= 180^\circ - 52^\circ - 80^\circ \\ \Rightarrow \angle BAD &= 48^\circ\end{align*}Thus, the measure of $\angle BAD$[/tex] is [tex]$48^\circ$[/tex].

Nathan eats approximately 44.76 burritos each month.The equation representing this situation is M + 10M + (10M - 14) = 80.

Let's denote the number of burritos Nathan's mom eats as M. Therefore, Nathan eats 10 times as many burritos, which would be 10M.

Additionally, Nathan's dad eats 14 fewer burritos than Nathan, so his consumption would be 10M - 14.

The total number of burritos eaten by the family each month is given as 80.  

To solve the equation, we combine like terms: M + 10M + 10M - 14 = 80. Simplifying further, we have 21M - 14 = 80. Next, we isolate the variable by adding 14 to both sides: 21M = 94.

Finally, we divide both sides by 21 to solve for M: M = 94/21. Evaluating this, we find M ≈ 4.476.

Therefore, the cost of white washing the walls will be Rs 5 × 588.72 = Rs 2943.60.

The total surface area of the four walls can be calculated by multiplying the perimeter of the room (2 × (length + width)) by the height of the room. In this case, the total surface area of the four walls is 2 × (16 + 14) × 10 = 600 square meters.

Next, we need to subtract the areas of the windows and doors from the total surface area of the walls. There are four windows with dimensions of 1.3 meters in height and 1.4 meters in width, so the total area of the windows is 4 × (1.3 × 1.4) = 7.28 square meters. There are also two doors with dimensions of 2 meters in height and 1 meter in width, so the total area of the doors is 2 × (2 × 1) = 4 square meters.

Subtracting the areas of the windows and doors from the total surface area of the walls, we get 600 square meters - (7.28 square meters + 4 square meters) = 588.72 square meters.

Finally, we can calculate the cost of white washing the walls by multiplying the rate per square meter (Rs 5) by the total surface area of the walls (588.72 square meters). Therefore, the cost of white washing the walls will be Rs 5 × 588.72 = Rs 2943.60.

In this specific system, one possible error could be made during the elimination method. When attempting to eliminate the variable "y," one might mistakenly multiply the second equation by 2 instead of -2. This would lead to incorrect coefficients and ultimately yield an incorrect solution for "x" and "y." Always check the steps, signs, and calculations to ensure accuracy when solving linear systems.

To plot a point at the location (-2.5, 3.75), start at the origin and move 2.5 units left along the x-axis because the x-coordinate is -2.5. Then, move 3.75 units up along the y-axis because the y-coordinate is 3.75.

To plot a point on a Cartesian coordinate system, you start at the origin (0, 0) and use the x and y coordinates to determine the position of the point. In this case, the x-coordinate is -2.5, which means you need to move left on the x-axis. Since -2.5 falls between -2 and -3, you move 2.5 units to the left from the origin.

Next, the y-coordinate is 3.75, indicating a movement along the y-axis. Since 3.75 falls between 3 and 4, you move 3.75 units up from the previous position. Combining these movements, you end up at the point (-2.5, 3.75) on the Cartesian plane.

It's important to note that the order of movement is significant. In this case, you move left along the x-axis first and then up along the y-axis. If the order were reversed, the resulting point would be different. By following the given set of statements, you correctly plot the point at the specified location.

The rock hits the ocean approximately 5 seconds after it is thrown upward from the cliff.

To determine when the rock hits the ocean, we can use the equations of motion for vertical motion under the influence of gravity. The key equation is:

h = ut - 1/2gt^2 Where:

h = height (in this case, 112 feet, as it starts from the top of a 112-foot cliff)

u = initial velocity (96 ft/s, as the rock is thrown upward)

g = acceleration due to gravity (32 ft/s^2, assuming no air resistance)

t = time (unknown, we want to find when the height is 0, i.e., when it hits the ocean)

Substituting the known values into the equation, we have:

0 = 96t - 1/2 * 32 * t^2

Rearranging the equation, we get:

16t^2 - 96t = 0

Factoring out t, we have:

16t(t - 6) = 0

This equation gives us two possible solutions: t = 0 and t = 6. However, t = 0 represents the initial time when the rock is thrown, so we disregard it. Therefore, the rock hits the ocean approximately 6 seconds after it is thrown upward.
