Answer:

18 white flowers

Step-by-step explanation:

We are given ratio:

Red : White

2 : 3

If Sally used 12 red flowers, how many white flowers will she use?

Let the number of white flowers Sally uses be represented by x

This is calculated as:

2/3 = 12/x

Cross Multiply

2 × x = 3 × 12

x = 3 × 12/2

x = 18 white flowers

Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.

Step-by-step explanation:

-12=9-3w

Subtract nine from both sides

-12=9-3w

-9. -9

-21=-3w

Answer:

  all of them, possibly excepting the 4th term

Step-by-step explanation:

The recursive formula is good if you have terms near the one of interest. It might be used for the 4th term, but that would require that you compute the three previous terms:

  7, 5, 3, 1 . . . . requires 3 subtractions

It can be about as easy to calculate ...

  a4 = 7 -2(3) = 1 . . . . requires two* subtractions and a multiplication

__

However, for the 7th, 11th, and 106th terms, it is impractical to list all previous terms. The explicit formula is a better choice.

A.  a4 = 7 -2(3) = 1

B.  a7 = -1 +10(6) = 59

C.  a106 = 2 +5(105) = 527

D.  a11 = -3 +4(10) = 37

_____

* The explicit formula is ...

  an = a1 +d(n -1)

The operations identified in this formula (in the order required by the Order of Operations) are subtraction, multiplication, and addition. For a negative common difference, that amounts to two subtractions and a multiplication.

For manual evaluation, the work involved in using the recursive or explicit formulas for the 4th term is about the same, if the arithmetic is easily done mentally (as here).

Answer: Its very simple to solve slopes

Step-by-step explanation:

All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Step-by-step explanation:

volume of square pyramid = area of base* 1/3*height of pyramid

v=a(1/3h)

a = area of base = 11*11 = 121

h=height = 15 cm

v=121 (1/3*15)

v = 121*5 = 605 cm^3

Answer:

6.02x10^8

Step-by-step explanation:

Answer:

Check the explanation.

Step-by-step explanation:

The slope-intercept form of the equation is

[tex]y=mx + b[/tex]

Line A:

[tex]y = 1 2 x + 2[/tex]

The slope of line A:

[tex]m_A=12[/tex]     ∵ comparing with [tex]y=mx + b[/tex]

Line B:

[tex]y = -1 2 x + 7[/tex]

[tex]m_B=-12[/tex]    ∵ comparing with [tex]y=mx + b[/tex]

Line C:

[tex]y = -2x + 4[/tex]

[tex]m_C=-2[/tex]     ∵ comparing with [tex]y=mx + b[/tex]

Line D:

[tex]y = 12x + 5 4[/tex]

[tex]m_D=12[/tex]     ∵ comparing with [tex]y=mx + b[/tex]

As we know that the product of the slopes of perpendicular lines is -1.

i.e. their slopes are opposite of the reciprocal of each other.

Now, let us check the OPTIONS:

Option A)  A and B

Check:

[tex]m_A=12[/tex]  

[tex]m_B=-12[/tex]

As the product of the slopes A and B is NOT -1, so the lines A and B are not perpendicular. Hence, option A is NOT true.

Option B)  A and C

[tex]m_A=12[/tex]  

[tex]m_C=-2[/tex]

As the product of the slopes A and C is NOT -1, so the lines A and C are not perpendicular. Hence, option B is NOT true.

Option C)  B and C

[tex]m_B=-12[/tex]

[tex]m_C=-2[/tex]

As the product of the slopes B and C is NOT -1, so the lines B and C are not perpendicular. Hence, option C is NOT true.

Option D)  A and D

[tex]m_A=12[/tex]  

[tex]m_D=12[/tex]

As the product of the slopes A and D is NOT -1, so the lines A and D are not perpendicular. Hence, option D is NOT true.

Therefore, NO OPTION is correct.

Answer: line HG

Step-by-step explanation:

The line which is intersecting the planes of GABH and FEHG will be line GH.

A collection of continuous, non-empty points that together form inextensible, non-deformable shapes are known as geometric figures.

A figure or region with a defined border that is formed by combining a specific number of curves, points, and lines is referred to as a geometric shape.

Another meaning of the geometrical figure is the figure which is in 2D and becomes by intersections of lines.

Given two plans GABH and FEHG

It is clearly visible that both plans are intersecting and separated by a line GH.

Step-by-step explanation:

The distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function d(t) = 500t represents the number of miles traveled in t hours.

Plug t = 3.5 hours in the equation of the function.

d(3.5) = 500(3.5)

d(3.5) = 1,750.0 miles

Thus, the distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

Given:

The set of points.

To find:

Which set of points represents a function?

Solution:

A set of points represents a function if there exist a unique y-value for each x-value.

It option A, the set of points is

{(1,-2), (3,-5), (3,-2), (5,-7), (7, -8)}

This is not a function because there exist two y-values y=-5 and y=-2 for x=3.

It option B, the set of points is

{(0,1),(1,−3),(2,−5),(3,−7),(4,−9)}

This is a function because there exist a unique y-value for each x-value.

It option C, the set of points is

{(−1,1),(−1,3),(−1,5),(−1,7),(−1,9)}

This is not a function because there exist five y-values y=1,3,5,7,9 for x=-1.

It option D, the set of points is

{(−4,0),(−3,−1),(−3,1),(0,−2),(0,2)}

This is not a function because there exist two y-values y=-1 and y=1 for x=-3.

Therefore, the correct option is B.

Answer:

Step-by-step explanation:

It is solved for C unless you C = 5/9 * F - 32*5/9

C = 5/9F - 17.8

=================

If you mean F, then Multiply both sides by  9/5

9/5 * C = F - 32

9/5  * C + 32 = F

=====================

A quick way to do this is to multiply by 2 and add 32

F = 2*C + 30

My wife, an American, always had to do this when she heard the daily temperatures in Canada.

first multiply both sides by 9/5 to get:

9/5C= F -32

Add 32 to both sides and transpose to get:

F=9/5C + 32

these are the formulas to translate between Fahrenheit and Celsius temperatures

Fahrenheit and Celsius meet at - 40 degrees

that is - 40 Fahrenheit = - 40 Celsius    

So alternitive formulas for the conversations can be written:

F=9/5 (C+40) - 40

C=5/9 (F+40) - 40

Answer:

0.4 ounces

Step-by-step explanation:

In a day

Miguel is to feed Chester ,

Chester can eat 3/4 of an ounce for each pound of body weight.

Chester weighs 6.8 pounds

Hence:

1 pound = 3/4 ounce

6.8 pounds = x ounces

Cross Multiply

x = 6.8 × (3/4) ounces

x = 5.1 ounces

Chester is to be fed 5.1 ounces of food each day.

The amount of food left after 1 day

= 5.5 ounces - 5.1 ounces

= 0.4 ounces

Hence, 0.4 ounces of food is left after 1 day

The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.

Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:

C = 2A

C = N + 3

C = S/2

S - N = C + A

S = 2C, N = C - 3 and A = C/2, therefore we have

2C - (C - 3) = C + C/2

C + 3 = C + C/2

C/2 = 3 and C = 6

A = C/2

A= 6/2

A = 3

N = C - 3

N = 6 - 3

N = 3

S = 2C

S = 2 x 6

S = 12.

C = 6, A = 3, N = 3 and S = 12

Answer:

data points or values are nearer to the mean

Step-by-step explanation:

Given that mean absolute deviation tells you how to spread out or how clustered around the mean a set of data is.

Hence, in a comparison of sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean.

On the other hand, a lower mean absolute deviation indicates that the data points are nearer to the mean than a data set with a higher mean absolute deviation

Fifteen is a factor of the number because both 3 and 5 are prime factors.

Step-by-step explanation:

The computation is shown below:

The cube of 2 is

The square of 3 is

= 3^2

= 9

Now if we multiplied the 3 digits that it would be
