Answer: 11,500 grams

Step-by-step explanation: 920/8=115 115*100= 11,500

Hello !

Answer:

\(\boxed{\sf x=-15}\)

Step-by-step explanation:

We are looking for the value of x that verifies the following equation :

\(\sf 2x-9=6+3x\)

To do this, we will have to isolate x.

Let's start by substracting 3x from both sides of the equality.

\(\sf 2x-9-3x=6+3x-3x\)

Then combine like terms :

\(\sf -x-9=6\)

Now let's add 9 to both sides :

\(\sf -x-9+9=6+9\\-x=15\)

Finally, let's multiply both sides by -1 :

\(\sf-1\times(-x)=-1\times 15\\\boxed{\sf x=-15}\)

Gabriella skied for 6 hours, Let x be the number of hours that Gabriella skied. We know that she paid $35 for ski rental and $15 per hour for skiing,

for a total of $95. We can set up the following equation to represent this information:

35 + 15x = 95

Solving for x, we get:

15x = 60

x = 4

Therefore, Gabriella skied for 6 hours.

Here is a more detailed explanation of how to solve the equation:

Subtract $35 from both sides of the equation.

15x = 60

15x - 35 = 60 - 35

15x = 25

Divide both sides of the equation by 15.

15x = 25

x = 25 / 15

x = 4

Therefore, x is equal to 4, which is the number of hours that Gabriella skied.

The height of Tree A t years after being planted can be represented by the equation:

A = 30 + 2t

This equation states that the initial height of the tree (30 inches) plus the annual growth of the tree (2 inches per year) multiplied by the number of years that have passed (t) will give the current height of the tree.

The height of Tree B t years after being planted can be represented by the equation:

B = 15 + 5t

This equation states that the initial height of the tree (15 inches) plus the annual growth of the tree (5 inches per year) multiplied by the number of years that have passed (t) will give the current height of the tree.

To determine which tree is taller after 6 years, we can substitute t = 6 into each equation and compare the results:

A = 30 + 2(6) = 30 + 12 = 42 inches

B = 15 + 5(6) = 15 + 30 = 45 inches

Tree B is taller than Tree A after 6 years because 45 inches is greater than 42 inches.

The shape of the sampling distribution of sample means from a sample of size 100 taken from a bimodal distribution of Red Delicious apple diameters with a mean of 2.63 in. and a standard deviation of 0.25 in. is approximately normal.

According to the central limit theorem, when the sample size is sufficiently large (typically greater than 30) and the population distribution is not severely skewed, the sampling distribution of sample means tends to approximate a normal distribution, regardless of the shape of the population distribution.

In this case, even though the population distribution of Red Delicious apple diameters is bimodal, the sample size of 100 is considered large enough for the central limit theorem to apply. As a result, the sampling distribution of sample means will be approximately normal.

This means that if we were to take multiple random samples of size 100 from the orchard and calculate the mean diameter for each sample, the distribution of those sample means would be bell-shaped and follow a normal distribution.

Therefore, the shape of the sampling distribution of sample means from the given sample size and population distribution is approximately normal.

To calculate the total charge within the cylinder with dimensions r=1.5 and h=3, we use the potential function V = 5r + 4 cos Ø in cylindrical coordinates.

The total charge can be obtained by integrating the charge density over the volume of the cylinder.

The potential V within the cylinder is given by V = 5r + 4 cos Ø, where r represents the radial distance from the axis of the cylinder and Ø represents the angle in the cylindrical coordinate system. To calculate the total charge within the cylinder, we need to integrate the charge density over its volume.

The charge density ρ can be related to the potential by ρ = -∇²V, where ∇² is the Laplacian operator. In cylindrical coordinates, the Laplacian operator takes the form:

∇² = (1/r) ∂/∂r (r ∂/∂r) + (1/r²) ∂²/∂ز + ∂²/∂z²

Since the potential function V does not depend on the z coordinate, the Laplacian reduces to:

∇² = (1/r) ∂/∂r (r ∂/∂r) + (1/r²) ∂²/∂ز

Applying this operator to the potential function V, we find:

∇²V = (1/r) ∂/∂r (r ∂V/∂r) + (1/r²) ∂²V/∂ز

To find the charge density, we substitute this expression into ρ = -∇²V:

ρ = -(1/r) ∂/∂r (r ∂V/∂r) - (1/r²) ∂²V/∂ز

To calculate the total charge, we integrate the charge density ρ over the volume of the cylinder:

Q = ∫∫∫ ρ dV = ∫∫∫ -(1/r) ∂/∂r (r ∂V/∂r) - (1/r²) ∂²V/∂ز dV

The integration is performed over the cylindrical coordinates r, Ø, and z, with appropriate limits. Evaluating this integral will give us the total charge within the cylinder.

The width and length of the chicken coop are 5.5 feet and 9.5 feet respectively.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle is given by P = 2L + 2W, where L is the length, W is the width and P is the perimeter.

We know that the width is w feet and the length is w+4 feet.

Given that the perimeter of the chicken coop is 30 feet, we can set up the following equation:

30 = 2(w + 4) + 2w

We can simplify this equation by combining like terms:

30 = 2w + 8 + 2w

30 = 4w + 8

22 = 4w

w = 5.5

So the width of the coop is 5.5 feet.

The relationship between food purchased and food eaten by dogs can be written as, 162 biscuits ≥ 80 biscuits

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

First, let's calculate the total number of dog biscuits that Jim has bought:

= 6 bags × 27 biscuits per bag

= 162 biscuits

Next, let's calculate how many biscuits the dog will eat in 4 weeks:

= 4 weeks × 5 biscuits per day

= 20 biscuits per week

20 biscuits per week × 4 weeks = 80 biscuits

So, Jim has bought 162 biscuits and his dog will eat 80 biscuits in 4 weeks. This means that Jim has brought enough dog biscuits for his dog for 4 weeks.

There are 658,008 ways to choose 5 non-Polluted lakes from the remaining 79 lakes.

To determine the number of ways to choose one polluted lake and five non-polluted lakes from a sample of 80 lakes, we can use the concept of combinations.

The total number of ways to choose a group of lakes from a larger set is given by the formula for combinations, which is denoted as "n choose r" and calculated as:

C(n, r) = n! / (r!(n-r)!)

Where n represents the total number of lakes and r represents the number of lakes to be chosen.

In this case, there are 80 lakes in the sample and we want to choose 1 polluted lake and 5 non-polluted lakes. Therefore, we have:

n = 80 (total number of lakes)

r = 1 (number of polluted lakes to be chosen)

Using the combination formula, we can calculate:

C(80, 1) = 80! / (1!(80-1)!)

         = 80! / (1! * 79!)

         = 80

So there are 80 ways to choose 1 polluted lake from the sample of 80 lakes.

Next, we want to choose 5 non-polluted lakes from the remaining 79 lakes (after choosing 1 polluted lake). Using the combination formula again:

C(79, 5) = 79! / (5!(79-5)!)

         = 79! / (5! * 74!)

         = 79 * 78 * 77 * 76 * 75 / (5 * 4 * 3 * 2 * 1)

         = 658,008

Therefore, there are 658,008 ways to choose 5 non-polluted lakes from the remaining 79 lakes.

To find the total number of ways to choose one polluted lake and five non-polluted lakes, we multiply the number of ways for each category:

Total number of ways = 80 * 658,008

                   = 52,640,640

Hence, there are 52,640,640 ways to choose one polluted lake and five non-polluted lakes from the given sample of 80 lakes.

Pack 216 cube-shaped boxes of edge 3 cm in a larger box with a volume of 5832 cubic cm.

The volume of each cube-shaped box is given by the formula:

\(V = edge^3\)

Substituting the value of edge as 3 cm, we get:

\(V = 3^3 = 27\) cubic cm

To find the number of boxes that can be packed in a larger box with a volume of 5832 cubic cm, we need to divide the volume of the larger box by the volume of each smaller box:

Number of boxes = Volume of larger box / Volume of each smaller box

Number of boxes = 5832 cubic cm / 27 cubic cm

Number of boxes = 216

The total angle X is 105 degree as X is the number paired with the bisector of angle LMN.

What is an Angle bisector ?

Angle bisector in geometry refers to a line that splits an angle into two equal angles. Bisector means the thing that bisects a shape or an object into two equal parts. If we draw a ray that bisects an angle into two equal parts of the same measure, then it is called an angle bisector.

If x is the bisector of ∠LMN then it would divide the angle in half.

∠OMN = 70

∠OML = 140

∠OML - ∠OMN = 140 - 70  = 70

If x is the bisector of ∠LMN then it would divide the angle in half.

∠NMx = 70/2 = 35

the total angle = ∠OMN + ∠NMx = 70 + 35 = 105

Therefore , The total angle X is 105 degree as X is the number paired with the bisector of angle LMN.
