Answer:

The largest advertisement she can afford has dimensions of 5 in x 10/3 in

Step-by-step explanation:

Assume the dimensions of the advertisement are L and W.

The area of the advertisement is:

A = L.W

The ratio length/width is 3:2, thus the proportion is:

[tex]\displaystyle \frac{L}{W}=\frac{3}{2}[/tex]

Thus:

[tex]\displaystyle L=\frac{3}{2}W[/tex]

The area is:

[tex]\displaystyle A=\frac{3}{2}W^2[/tex]

Since the square inch of advertisement space sells for $3, the cost for Anna to purchase it is:

[tex]\displaystyle C=3\cdot\frac{3}{2}W^2[/tex]

Simplifying:

[tex]\displaystyle C=\frac{9}{2}W^2[/tex]

This cost can be a maximum of $50, thus:

[tex]\displaystyle \frac{9}{2}W^2=50[/tex]

Multiplying by 2:

[tex]9W^2=100[/tex]

Solving for W:

[tex]\displaystyle W=\sqrt{\frac{100}{9}}=\frac{10}{3}[/tex]

[tex]\displaystyle W=\frac{10}{3}[/tex]

And

[tex]\displaystyle L=\frac{3}{2}\cdot \frac{10}{3}[/tex]

L = 5

Thus the largest advertisement she can afford has dimensions of 5 in x 10/3 in

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The real surface area is between 214.9 square inches and 668.3 square inches.

The mistaken surface area found by Jayden is 443 square inches.

In this problem we find a right angled parallelepiped whose dimensions are known. The surface area of the parallelepiped is the sum of the areas of the six faces. There are three pairs of faces with the following dimensions:

Pair 1

A' = (4.92 in) · (15.3 in)

A' = 75.276 in²

Pair 2

A'' = (15.3 in) · (7.28 in)

A'' = 111.384 in²

Pair 3

A''' = (4.92 in) · (7.28 in)

A''' = 35.818 in²

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The range of measures for the area of the parallelepiped is represented by the following inequality:

6 · 35.818 in² < 444.956 in² < 6 · 111.384 in²

214.908 in² < 444.956 in² < 668.304 in²

The real surface area is between 214.9 square inches and 668.3 square inches.

Lastly, the mistaken surface area found by Jayden is:

A = 2 · (4.92 in) · (15.1 in) + 2 · (111.384 in²) + 2 · (35.818 in²)

A = 442.988 in²

The mistaken surface area found by Jayden is 443 square inches.

There are 462 different ways can be done for a promotional program.

Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

Selection of menu, food, clothes, subjects, the team are examples of combinations.

The formula for combinations is: nCr = n!/[r! (n-r)!]

nCr represents the number of combinations from “n” objects taken “r” at a time.

given that

select 6 restaurants from 11.

nCr = n!/[r! (n-r)!]

we are looking at a Combination of 11 things takes 6 at a time, or 11C6

11C6=11!/(6!5!)

11C6=11×10×9×8×7 / 5×4×3×2×1.

11C6=55440 / 120

11C6=462

Thus, there are 462 different ways in which the manager can choose 6 restaurants at a time out of 11.

Answer:

1100

Step-by-step explanation:

Answer:

There will be 18 grams left after 12 hours.

Step-by-step explanation:

Half-life is the amount of time it take for a cell to turn from one condition to another.

To find the amount of grams for the first 6 hours.

72 ÷ 2= 36

Now, since 6 x 2 = 12, we need to divide 36 by 2 to find the next half-life.

36 ÷ 2 = 18

Therefore, there will be 18 grams left after 12 hours.

Hope this helps! :D

Explanation:

I recommend drawing out the number line. Plot -16 and 14 on it.

Either count out the spaces, or subtract and apply absolute value, to find the distance from -16 to 14 is exactly 30 spaces.

----------

Or you can think of it like this:

From -16 to 0 is 16 spaces

From 0 to 14 is another 14 spaces

That's 16+14 = 30 spaces total.

----------

In short, segment CD is 30 units long.

Point E is somewhere on segment CD.

x = distance from E to C

y = distance from E to D

x+y = EC+ED = CD = 30

x+y = 30

y = 30-x

We're told the distance from E to C is 1/4 the distance from E to D, so,

x = (1/4)*y

x = (1/4)*(30-x)

x = 0.25*(30-x)

x = 7.5 - 0.25x

x+0.25x = 7.5

1.25x = 7.5

x = (7.5)/(1.25)

x = 6

The distance from E to C is 6 units.

This means we'll add 6 units to the location of point C to find out where to place E

E = C+6 = -16+6 = -10 is the final answer

2 x 4 = 8

8 / 4 = 2

Answer: formula - (x/4)+x

Step-by-step explanation:

Since there are no numbers, here is just the formula and what it means :)

(x/4)+x

(btw x is whatever your number is)

so what you need to do first is to divide your number by 4 because 25% is 1/4 of 100%

and then add that number that you just got to your number.

Its a little confusing to say out in words, so here is an example using 24

24/4=6

24+6=30

and heres another example using 50

50/4=12.5

50+12.5=62.5

The 40th percentile is (1.6 + 1.6) / 2 = 1.6

What is percentile ?

In statistics, a k th percentile is a score below which a given percentage k of scores in its frequency distribution falls or a score at or below which a given percentage falls.

The data are in ascending order.

Compute the position of the pth percentile (index i):

i = (p/100)*n

i = (40/100)*50

i = 20

The index i is an integer ⇒ the 40th percentile is the average of the values in the 19th and 20th positions (1.6 and 1.6 respectively).

Therefore, the 40th percentile is (1.6 + 1.6) / 2 = 1.6

The required equation which represents the expression of Celsius temperature as a linear function of the Fahrenheit temperature is; C = (9/5)F - 57.6.

It follows from the task content that the linear equation which relates both the Celsius and Fahrenheit temperature is to be determined.

On this note, the two points which can be inferred to describe the linear relationship are;

(32, 0) and (212, 100)

Hence, the slope of the linear equation;

m = (C2 - C1)/(F2 - F1)

m = (212 - 32)/(100 - 0)

m = 180/100

m = 9/5

Hence, from the point-slope equation form; (y-y1) = m (x -x1).

We have; (C - 0) = (9/5) (F - 32)

C = (9/5)F - 57.6

Answer:

Oy=2x+3

Step-by-step explanation:

The function that has the {y} - intercept as that of the function graphed is y = 2x + 3

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the linear function that has the same y-intercept as the one that is represented by the graph.

The function graphed has the {y} - intercept of 3.

For the functions given -

Functions              {y} - intercept

y=2x-4                        -4

y=2x-3.                       -3

y=2x+3                        3

y=2x+4                        4

So, the function that has the {y} - intercept of 3 is y = 2x + 3.

Therefore, the function that has the {y} - intercept as that of the function graphed is y = 2x + 3.
