Given the height of a giraffe (20 ft) how tall would it be if you added 40 more different giraffes? Please explain your answer.

Step-by-step explanation:

7y = 9x-27

sub 7x = 9x-27 into 2nd eqn

45 + (9x-27) = 9x

move 9x over

18 = 9x - 9x

18 = 0

this doesn't make sense, so eqn has no solution

Answer:

The system has no solution

Step-by-step explanation:

Answer: a = 6

Step-by-step explanation:

The slope of the line is -1/2 so if y = -4, x = 6. In your case, x is a.

Hope this helps!

Step-by-step explanation:

Let the width be x ,

then length=(8+x),

A/Q,

l×b = area

=>x×(8+x)=105

=>8x+x²=105

=>8x+x=√105

=>9x=√105

=>9x=10.246950765959598

x=1.138550085106622

a) To calculate the standard error of the mean number of inclusions, we divide the sample standard deviation by the square root of the sample size. In this case, the sample mean number of inclusions is 31.0635, and the sample standard deviation is 2.0996. The sample size is 30. Therefore, the standard error of the mean number of inclusions can be calculated as follows:

Standard Error = Sample Standard Deviation / √Sample Size

Standard Error = 2.0996 / √30 Standard Error ≈ 0.3836 (rounded to four decimal places) b) To estimate a 95% confidence interval for the mean number of inclusions per tourmaline gem, we can use the formula: Confidence Interval = Sample Mean ± (Critical Value × Standard Error) The critical value corresponds to a 95% confidence level, which is 1.96 for a large sample size. Using the standard error calculated in part (a) as 0.3836 and the sample mean of 31.0635, the confidence interval can be calculated as: Confidence Interval = 31.0635 ± (1.96 × 0.3836)

Confidence Interval ≈ 31.0635 ± 0.7521 Confidence Interval ≈ (30.3114, 31.8156) (rounded to four decimal places) Therefore, we can estimate with 95% confidence that the mean number of inclusions per tourmaline gem lies between approximately 30.3114 and 31.8156.

Sure, here is the formula for the perimeter of a rectangle with a length of 5 inches:

Perimeter = 2(5 + w)

where:

Perimeter is the total length of all the sides of the rectangle, in inches

5 is the length of one side of the rectangle, in inches

w is the width of the rectangle, in inches

The variable w depends on the variable 5, because the width of the rectangle cannot be greater than the length of the rectangle.

Here is an example of how to use the formula:

If the length of the rectangle is 5 inches and the width is 3 inches, then the perimeter is:

Perimeter = 2(5 + 3)

= 2(8)

= 16 inches

Answer:

AB=15  BD=18

Step-by-step explanation:

AB is 15 because AB=AC and AC is 15

BD:

Using the Pythagorean Theorem

10²+15²=√325

√325=18

10 is from AB-CD

15 is the height which is AC

Answer:

BD = 5, and AB = 15 :)

Answer & Step-by-step explanation:

I can't draw the image, but I can explain it to you.

Since 1 unit was 3 units and now it's 9, you would have to divide each side by 3. So, the width would be 1 unit and the length would be 2 units.

I hope this helped!!!

The scale of 1 unit = 9 m

The rectangle 1 unit = 3 m is similar to 1 unit = 9 m

Since the unit of the scale is reduced the image size will be smaller than the given diagram.

In Euclidean geometry,  objects are comparable if they have an identical shape, or if one has the same form because they reflect a photograph of the other. more precisely, one can be obtained from the opposite by using uniformly scaling (enlarging or lowering), probably with extra translation, rotation and reflection.

Answer:

1m/s^2

Step-by-step explanation:

the formula for acceleration is change in velocity divided by time

the change in velocity is 4m/s (subtract 5 from 9)

the change in time is 4 seconds

so 4m/s ÷ 4s

this gives you 1m/s^2

This number does not correspond to the correct product of 243,192 multiplied by 4.

Rae's method appears to involve breaking down the numbers into their components and performing the multiplication operations separately. Let's analyze her answer:

243, 192 x 4 - 8 | 16 12 | 4 | 36 | 8 1

It seems that she broke down the number 243,192 into its individual digits (2, 4, 3, 1, 9, and 2) and performed separate calculations for each digit. However, her approach is not mathematically accurate or coherent.

Now, let's translate Rae's answer into a number that can be understood in base 10:

243,192 x 4 - 8 | 16 12 | 4 | 36 | 8 1

If we reassemble the digits without the vertical separators, we get: 8161243681.

However, this number does not correspond to the correct product of 243,192 multiplied by 4.

To find the correct answers using Rae's method, let's apply it to the provided multiplication exercises:

156 x 3:

Applying Rae's method:

156 x 3 - 6 | 15 18 | 3

Reassembling the digits: 6153183

The correct answer: 156 x 3 = 468

2873 x 2:

Applying Rae's method:

2873 x 2 - 6 | 14 16 | 3

Reassembling the digits: 614163

The correct answer: 2873 x 2 = 5746

71,181 x 5:

Applying Rae's method:

71,181 x 5 - 5 | 35 25 | 5

Reassembling the digits: 535255

The correct answer: 71,181 x 5 = 355,905

3,726,510,392 x 2:

Applying Rae's method:

3,726,510,392 x 2 - 4 | 7 14 12 10 | 3

Reassembling the digits: 471412103

The correct answer: 3,726,510,392 x 2 = 7,453,020,784

Answer:

Slope = 3/7

y - intercept: y = -3

x - intercept x = 7

Step-by-step explanation:

You have to cimplify the equation in terms of y

-3x +7y= -21

7y= 3x-21

y = 3/7x - 3

SLOPE: It is whatever x is mutlipliedby

slope would be 3/7

Y intercept: you need to plug in x=0

y = 3/7(0) - 3

Zero multipled by anything is zero so you are left with

y = -3

X intercept: plug in y = 0

0 = 3/7x - 3

Move the -3 to the other side

3 = 3/7x

Multiply by the reciprocal 7/3

x = 7/3 * 3

x = 21/3

x = 7

FV= $1,937,719.58

Step-by-step explanation:

Giving the following information:

Quarter deposit= $10,000

Number of periods= 20*4= 80

Interest rate? 0.08/4= 0.02

To calculate the future value, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= quarter deposit

FV= {10,000*[(1.02^80) - 1]} / 0.02

FV= $1,937,719.58

We are given a set of vectors S in M₂₂ and we need to show that S is linearly independent. We then deduce that S is a basis for M₂₂. Additionally, we are asked to express vector A as a linear combination of the vectors in S and find the coordinates of A with respect to the basis S.

To show that S is linearly independent, we need to demonstrate that the only solution to the equation c₁v₁ + c₂v₂ + c₃v₃ = 0, where c₁, c₂, and c₃ are scalars, is c₁ = c₂ = c₃ = 0. Here, v₁, v₂, and v₃ are the vectors in S.

Let's consider the vectors in S:

v₁ = {[H, 3H, H]}

v₂ = {[H², H], 24}

v₃ = {[-15, 1], 5}

To show linear independence, we set up the equation c₁v₁ + c₂v₂ + c₃v₃ = 0 and solve for c₁, c₂, and c₃.

c₁{[H, 3H, H]} + c₂{[H², H], 24} + c₃{[-15, 1], 5} = 0

By comparing the corresponding entries on both sides of the equation, we obtain the following system of equations:

c₁H + c₂H² - 15c₃ = 0

3c₁H + c₂H + c₃ = 0

c₁H + 24c₂ + 5c₃ = 0

We can solve this system of equations to find c₁, c₂, and c₃. If the only solution is c₁ = c₂ = c₃ = 0, then S is linearly independent.

To deduce that S is a basis for M₂₂, we need to show that S is linearly independent and spans the entire space M₂₂. Since we have shown linear independence, we now need to demonstrate that S spans M₂₂. To do this, we need to show that any matrix in M₂₂ can be expressed as a linear combination of the vectors in S.

Finally, to express vector A = {[-15, 1], 5} as a linear combination of the vectors in S, we solve the equation c₁v₁ + c₂v₂ + c₃v₃ = A for the coefficients c₁, c₂, and c₃. Once we find the coefficients, we can write (A)s to represent the coordinates of A with respect to the basis S.

In conclusion, to summarize the answer, we have shown that S is linearly independent, which implies that S is a basis for M₂₂. We can express vector A as a linear combination of the vectors in S and find its coordinates with respect to the basis S. However, the specific calculations to find the coefficients and coordinates are not provided in the question.
