Answer: [tex]2.78m^{2}[/tex]

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = [tex]625m^{2}[/tex].

scale of the statue replica = 1:15.

solution:

[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]

[tex]= \frac{625m^{2} }{225}[/tex]

= [tex]2.78m^{2}[/tex]

the area of the replica is [tex]2.78m^{2}[/tex]

Answer:

2.78 m^2 is the correct answer. :)

Answer:

$84

Step-by-step explanation:

720x30=21600

21600/100=216

216=markdown (as a number instead of a percentage)

Now subtract that like this

720-216=504

504= sale price

Then do this

504-420=84

Therefore it is $84

Answer:

Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".

Answer:

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

Median = 5

Mean = 5.4444444444444

Mode: 3

Range = 9

Minimum =   1

Maximum =  10

How to find Median:

Arrange your numbers in numerical order.  Then the second step is to have an odd number, divide by 2 and round up to get the position of the median number.  The last step is to find the even number and if you have it, divide it by 2.

Answer:

$6,984.60 per year.

Step-by-step explanation:

Using a normal and very common budget, you should divide your monthly/annual salary into 3 main tiers, which are the following

If we go by this budget then we would need to turn the 20% into a decimal by dividing it by 100 and then multiply that decimal by the person's annual salary.

20% / 100 = 0.20

$34,923 * 0.20 = $6,984.60

Finally, we can see that the individual should be saving roughly $6,984.60 per year.

Answer:

They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.

Step-by-step explanation:

All we have to do is add the number of marbles they collected.

510 + 842 = 1,352

1,352 rounded to the nearest hundred is 1,400.

Your question isn't really clear but let me help.

For Maths test,

Point earned = 30

Total point = 43

Percentage = 30/43 × 100 = 69.77%

Social studies test

Point earned = 85.

Total point = 124

Percentage = 85/124 × 100 = 68.55%

From the above, we can see that Jake scored a higher percentage in the Maths test.

Answer:

  168

Step-by-step explanation:

Below are shown the 7 different kinds of arrangements that can be made. Each of these can be permuted into 24 different arrangements by assigning colors in a different order than the one used here:

  {1, 2, 3, 4} ⇒ {green, blue, red, yellow}

Then the total number of possible correct colorings is 7·24 = 168.

__

These colorings were found using a computer program that identified all 168 viable colorings, then eliminated permutations. It started by identifying ways to color 2 rows, then adding rows based on that.

Answer:

b) 18

Step-by-step explanation:

600 - 150 = 450

25x = 450

x = 18

check

25 x 18 = 450

450 + 150 = 600

Answer: $54.35

Step-by-step explanation:

If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:

15*X

And the minimum amount they need to collect is $800

Then we will have the inequality:

15*X ≥ $800

Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:

(15*X)/15 ≥ $800/15

X ≥ $54.33...

Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.

Then the inequality is:

X ≥ $54.35

This means that the minimum amount that each one of the 15 students needs to collect is $54.35

Step-by-step explanation:

log(7x³/z) = log(7) + log(x³) - log(z).

3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

Step-by-step explanation:

The polar form of z is 6√2(cos(135°) + isin(135°)).

Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as  z = r cosθ + i r sinθ = r (cosθ + i sinθ).  the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is  A = x + i y

Given the point z

From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.

The square root of the sum of the squares of z's components determines its magnitude:

|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]

here x = -6 and y = 6

|z| = √(-6²) + (6²)

z = 6√2

polar form is

z = 6√2(cos(135°) + isin(135°))

Hence the complex form is 6√2(cos(135°) + isin(135°)).
