Answer:

10

Step-by-step explanation:

i think its 10 maybe cuz if u see

the perimeter of a rectangular room is 52 feet. right?

then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!

now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10

Volume of cylinder

πr²h = π×(12)²×(18)

Choco : Vanilla : Strawberry

3 : 2 : 1

to find volume of strawberry,

[tex] \frac{1}{6} \times volume \: of \: cylinder[/tex]

then use your calculator

Answer:

The solution is possible

Step-by-step explanation:

Given

[tex]f(x) = 5 * 2^x[/tex]

Required

Is an output of 200, possible?

To know if it is possible or not, we start by substituting 200 for f(x)

[tex]200 = 5 * 2^x[/tex]

Divide both sides by 5

[tex]\frac{200}{5} = \frac{5}{5} * 2^x[/tex]

[tex]\frac{200}{5} = 2^x[/tex]

[tex]40 = 2^x[/tex]

[tex]2^x =40[/tex]

Take logarithm of both sides

[tex]log2^x =log40[/tex]

Apply law of logarithm

[tex]xlog2 =log40[/tex]

Divide both sides by log2

[tex]x = \frac{log40}{log2}[/tex]

[tex]x = \frac{1.6021}{0.3010}[/tex]

[tex]x = 5.32[/tex]

for f(x) = 200, x is approximately 5.32

Hence, the solution is possible

Answer:

D) y =   -2

The equation of the perpendicular line to the given line is  y = -2

Step-by-step explanation:

Explanation:-

Given point (-3,-2)

In graph the equation of line  x = 8 ( parallel to y- axis )

                              1 x + o y - 8 =0

The equation of the perpendicular line to the given line  

                        b x - a y + k =0

                       o x - 1 y + k =0 ...(i)

The equation (i) is Paases through the point ( -3,-2)

                        0 ( -3) -1(-2) + k =0

                               2 + k =0

                                     k = -2

∴The equation of the perpendicular line to the given line  is

     put k = -2 in equation (i)    

                        o x - 1 y + k =0

                      - y +(-2) =0

                       - y = 2

                         y = -2

Final answer:-

∴The equation of the perpendicular line to the given line is  y =-2

Answer:

Their expenses and sales will both equal at 200 ounces.

Step-by-step explanation:

This can be determined using the break-even point in ounce formula as follows:

Break even point in ounce = Fixed cost / Contribution per ounce

Where;

Fixed cost = Advertising = $600

Contribution per ounce = Selling price per ounce - Cost per ounce = $4 - $1 = $3

Substituting the values into equation (1), we have:

Break even point in ounce = $600 / $3 = 200 ounces

Therefore, their expenses and sales will both equal at 200 ounces.

Oh sunday sheldon bought 4 1/2 kg of plant food,he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.How many kg of palnt food did sheldon have left?

Answer:

2 7/12 kg

Step-by-step explanation:

Oh sunday sheldon bought 4 1/2 kg of plant food,he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.How many kg of palnt food did sheldon have left?

Step 1

We add up the kg of plant food that he used

He used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.

The total amount of plant food that he used = 1 2/3 kg + 1/4 kg

Lowest Common Denominator 12

1 + (2/3 + 1/4)

1 + (8 + 3/12)

1 11/12 kg of plant food

Hence he has used 1 11/12 kg of plant food

Step 2

The amount of plant food that he had left is calculated as:

Amount of plant food Sheldon bought - Amount of plant food he used

Amount of plant food Sheldon bought = 4 1/2 kg

The amount of plant food that he had left = 4 1/2 kg - 1 11/12

4 - 1 + (1/2 - 11/12)

Lowest common denominator = 12

3 + ( - 5/12)

= 2 7/12 kg

Therefore, the kg of plant food that sheldon had left = 2 7/12 kg

Answer:

The values of x that make the triangles congruent.

x = 6 and x = 3

Step-by-step explanation:

Given

Given that the triangles are congruent.

According to the SAS (Side-Side-Side)

AC = DC

AB = DB

so

AC = DC

substituting AC = 5x-2 and DC = 3x+10

5x-2 = 3x+10

5x-3x = 10+2

2x = 12

divide both sides by 2

2x/2 = 12/2

x = 6

and

AB = DB

substituting AB = 5x and DB = 4x+3

5x = 4x+3

5x-4x = 3

x = 3

Therefore, the values of x that make the triangles congruent.

x = 6 and x = 3

She is right, however her explanation is wrong.

In order to find the unit price, you need to divide the amount by the cost.

You will then see that 12 divided by 2.39 < 18 divided by 3.39.

The smaller unit price is obviously the better buy.

Answer:

2689.78

Step-by-step explanation:

FV = PV ( 1 + [tex]\frac{r}{m}[/tex])^mn

FV = Future value  

P = Present value  = 2000

R = interest rate   = 10%

N = number of years  = 3

M = number of compounding  = 4

2000 x (1 + 0.1/4)^4x3 = 2689.78

Answer:

The trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph

Step-by-step explanation:

Step 1

We calculate the speed of the trucker

Speed = Distance(miles)/Time(hours)

Distance = 159 miles

Time = 2 hours

Speed = 159 miles/2 hours

Speed = 79.5 miles per hour = 79.5 mph

From the question, we are told that: that toll road has a speed limit of 65mph

Step 2

We calculate the difference

= 79.5 mph - 65 mph

= 14.5 mph

Hence, the trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph

Answer:

μₓ = 36,000 dollars

σ ₓ= 1,000 dollars

Step-by-step explanation:

to find μₓ = 36,000 dollars:

Look in the question, it states that the mean is $36,000.

to find σ ₓ= 1,000 dollars:

[tex]\frac{3000}{\sqrt{9} } = 1000[/tex]

The mean and standard deviation of the sampling distribution is $36000 and $1000.

What is Standard Deviation?

The term "standard deviation"  refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

The mean and the standard deviation of the sampling distribution of the sample mean:

Mean, [tex]\mu[/tex] = $36000

[tex]\sigma[/tex] = 3000

n = 9

So, standard deviation of the sampling distribution

=  [tex]\sigma[/tex] / √n

= 3000 / √9

= 3000/3

= 1000

Hence, Mean = $36,000 and standard deviation = $1000.

Answer:

x = (c - k) / 3

Can you insert an image or retype the question, it is hard to read with the information that is incorrectly placed.

Answer:

f^-1 (x) = 2X + 8

Step-by-step explanation:

Let's make f(x) = y

Y = X/2 - 4

So to find the inverse, switch the y with the x like so:

X = Y/2 - 4 (isolate the Y value)

X + 4 = Y/2 (multiply both sides by 2)

2(X + 4) = Y

Y = 2X + 8

So f^-1 (x) = 2X + 8

Incomplete question. I provided an explanation about the term, "business model."

Explanation:

Usually, when mention is made of the term business model it simply refers to the decided way a business plans to make profits.

In other words, it includes information about services or products to be offered by the business in other to keep the business alive, but not just been alive but to continue growing profit-wise.

Hence, we can say, Henry's business model should contain information about the dog charges which would be profitable to his business.

Answer:

Number of units of first product = 112

Number of units of second product = 400

Step-by-step explanation:

Given that there are two products which are to be shipped.

First product details:

Unit volume = 10 cu ft

Weight of one unit = 50 lb

Second product details:

Unit volume = 3 cu ft

Weight of one unit = 40 lb

Total volume that can be carried by a truck = 2320 cu ft

Total weight that can be carried by a truck = 21600 cu ft

To find:

The number of units of each product that can be transported in one shipment in the truck?

Solution:

Let number of units of first product = [tex]x[/tex]

Let number of units of second product = [tex]y[/tex]

We can write down two linear equations in two variables here and solving them will give us the answer we are required to find.

As per question statement, the equations can be written as:

[tex]10x+3y = 2320 ...... (1)\\50x+40y = 21600\\\Rightarrow 5x+4y = 2160...... (2)[/tex]

Multiplying equation (2) with 2 and subtracting equation (1) from it:

[tex]8y - 3y = 4320-2320\\\Rightarrow 5y = 2000\\\Rightarrow \bold{ y = 400}[/tex]

By equation (1):

[tex]10x+1200 = 2320\\\Rightarrow 10x = 1120\\\Rightarrow \bold{x = 112}[/tex]

Answer is:

Number of units of first product = 112

Number of units of second product = 400
