Answer:

\(\large\boxed{\fcolorbox{x=10 }{}{}}\) OR \(\large\boxed{\fcolorbox{x=-10 }{}{}}\)

Let's solve the equation step-by-step:

First, you must find the square root:

x = ± \(\sqrt{100}\)

We know that 10 × 10 = 100 and -10 x -10 is 100

that means that the square root is either  10 or -10

And we also know that \(10^2\) \(-10^2\) are both 100

meaning that x = \(10^2\) OR \(-10^2\)

Answer:

16 + 64 + 64 are the 3 sides.

Step-by-step explanation:

There are two sides that are 4 times the third side.

Let the 3rd side = x

4x + 4x + x = 144 inchines

9x = 144 inches

x = 144/9

x = 16 inches.

So the base (which is the smallest side) = 16 inches.

One of the two sides remaining is 4x = 4*16 = 64

The other side = 64

Check

64 + 64 + 16 = 144 as it should.

The number of reindeer in St. Elsewhere in 1920 will be approximately 475.

The growth rate of .12 indicates an annual increase of 12%, meaning that each year the number of reindeer will be multiplied by 1.12. To find the number of reindeer in 1920, we need to use this growth rate over the 20-year period from 1900 to 1920.
Starting with the initial 52 reindeer, we can multiply by 1.12 for each year. This gives us:
Year 1: 52 * 1.12 = 58.24
Year 2: 58.24 * 1.12 = 65.10
Year 3: 65.10 * 1.12 = 72.90
Year 4: 72.90 * 1.12 = 81.60
Year 5: 81.60 * 1.12 = 91.15
Year 6: 91.15 * 1.12 = 101.66
Year 7: 101.66 * 1.12 = 113.27
Year 8: 113.27 * 1.12 = 126.13
Year 9: 126.13 * 1.12 = 140.43
Year 10: 140.43 * 1.12 = 156.36
Year 11: 156.36 * 1.12 = 174.16
Year 12: 174.16 * 1.12 = 194.10
Year 13: 194.10 * 1.12 = 216.45
Year 14: 216.45 * 1.12 = 241.58
Year 15: 241.58 * 1.12 = 269.87
Year 16: 269.87 * 1.12 = 301.72
Year 17: 301.72 * 1.12 = 337.62
Year 18: 337.62 * 1.12 = 378.10
Year 19: 378.10 * 1.12 = 423.77
Year 20: 423.77 * 1.12 = 475.30
Therefore, the number of reindeer in St. Elsewhere in 1920 will be approximately 475.

Step-by-step explanation:

Step-by-step explanation:

The calculated volume of the cube is 10714.1 cubic inches

From the question, we have the following parameters that can be used in our computation:

\(A = V^{2/3}\)

Where

A = Surface area

V = Volume

From the question, we have

Surface area of 486

This means that

A = 486

So, we have

\(V^{2/3} = 486\)

Take the 3/2nd root of both sides

So, we have

V = 10714.1

Hence, the volume of the cube is 10714.1 cubic inches

Answer:

1176in^2

Step-by-step explanation:

find the surface area of the cube

(14*14)6=1176 inches cubed

14*14 is finding the area of one side and then we multiply it by six because that's how many congruent sides there are

Answer:

\(\large\boxed{1,176 in^{2} }\)

Step-by-step explanation:

The cube is 14 inches tall

All of the sides in a cube are the same, which means:

Length = 14 inches

Width = 14 inches

Height = 14 inches

There are 6 sides in a cube. Each side has a length and a width.

We can use the following formula to find the surface area (SA) of the cube, or how much wrapping paper Jayde will use.

SA = # of Sides(Length(Width))

Plug in known values

SA = 6((14)(14))

The 14s represent the length and width while the 6 represents the number of sides in the cube.

Solve/Simplify

SA = 6(196)

SA = 1,176 inches²

Jayde will need to use 1,176 in² of wrapping paper to wrap the whole present.

Answer:

12:00 am midnight

Step-by-step explanation:

Given;

I can read a 336-page book in 6 hours.

My rate r1 = 336/6 pages per hour = 56 pages per hour

Jayne can read a 144-page book in 3 hours.

Jayne rate r2 = 144/3 = 48 pages per hour

If I start reading a 5000-page book at noon and Jayne starts reading the same book at 10 AM

Taking 10 am as the reference time.

Let x represent the time from 10 am at which they would both be on the same page.

For me;

Since i started by noon; 2 hours after 10 am

Time t1 = x-2

For Jayne;

She started by 10 am

Time t2 = x

For them to be on the same page they must have read the same number of pages;

Number of pages read = rate × time

r1(t1) = r2(t2)

Substituting the values;

56(x-2) = 48(x)

56x - 112 = 48x

x(56-48) = 112

x = 112/(56-48)

x = 14 hours

Since 10 am is the reference, the time would be;

=10 am + x = 10 am + 14 hours

= 24:00

= 12:00 am midnight

The nearest integer, the estimated value of the square root of 172 is 13.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variable and constants.

One way to estimate the square root of 172 is to find the two perfect squares that surround it. Since 12*12= 144 and 13*13 = 169, we know that the square root of 172 must be between 12 and 13.

To get a better estimate, we can calculate the midpoint between 12 and 13:

(12 + 13) / 2 = 12.5

We can then check if the square of this midpoint is closer to 172 than the squares of 12 and 13:

12*12 = 144

13*13 = 169

12.5*12.5 = 156.25

Since 172 is closer to 156.25 than it is to 169, we can estimate the square root of 172 to be 13.

Therefore, to the nearest integer, the estimated value of the square root of 172 is 13

The perimeter of the preimage polygon is equal to the perimeter of the image polygon during a rigid motion.

A rigid motion is a means to move every point in the plane such that (a) the relative distance between points stays the same and (b) the relative position of the points maintains the same.

The perimeter of a form is the space surrounding its edge.

In the question, we are given that a polygon is transformed by a rigid motion.

We are asked about the relationship between the perimeters of the preimage polygon and the image polygon.

In rigid motion, the distance between the points is always the same.

Thus, the perimeter will also be same, as the perimeter is the total length of the boundary of a polygon.

Thus, the perimeter of the preimage polygon is equal to the perimeter of the image polygon during a rigid motion.

the inequality on the graph is:

6y + 2x < 9

On the grid we can see a dashed linear equation with a negative slope (because it goes downwards) and we also can see that the shaded region is below the line.

Then we have something like:

y  < ax + b

On the diagram we can see that the y-intercept is 3/2, then:

y < a*x + 3/2

We also can see the point (1.5, 1)

Replacing that we will get:

1 = a*1.5 + 1.5

1 - 1.5 = a*1.5

-0.5 = a*1.5

-(1/2)*(2/3) = a

-1/3 = a

Then the inequality is:

y < (-1/3)x + 3/2

Now we can rewrite this as:

y + (1/3)x < 3/2

2y + (2/3)*x < 3

6y + 2x < 9

ANOVA is used when you have quantitative DV and IV with 3 or more levels, which means the correct answer is option A. True.


The One Way Repeated Measures ANOVA is a statistical test used to analyze the effects of an independent variable (IV) that has three or more levels on a dependent variable (DV) that is measured repeatedly on the same subjects over time. This test is appropriate when the IV is within-subjects in nature, meaning that each participant is exposed to all levels of the IV. Therefore, the statement is true as it accurately describes the use of this statistical test in relation to the IV and DV.
A. True

The One-Way Repeated Measures ANOVA is indeed used when you have a quantitative Dependent Variable (DV) and an Independent Variable (IV) with three or more levels that is within subjects in nature. In this case, the same subjects are exposed to different conditions or levels of the IV, allowing for the analysis of differences in the DV across those conditions.

To solve for x, we just need to compute the inverse of A (if it exists) and multiply it by b. If A is invertible, then this method will give us the unique solution to the linear system Ax=b.

To solve a linear system of the form Ax=b using inverse matrices, we can first find the inverse of matrix A (if it exists) and then multiply both sides of the equation by \(A^-1\), giving us:

\(A^-1Ax = A^-1b\)

Since\(A^-1A\) is the identity matrix I, we can simplify the left-hand side to just x:

\(x = A^-1b\)

However, it's worth noting that computing the inverse of a matrix can be computationally expensive, particularly for large matrices.

So, while using inverse matrices can be a useful technique for solving small systems, it may not be the most efficient approach for larger systems. In those cases, other techniques such as Gaussian elimination or LU decomposition may be more appropriate.
