Answer:

30%

Step-by-step explanation:

The price for each shirt to buy is: $ 700/100 = $ 7 / each

Selling price is: $ 10 / each

So the difference between the selling and buying prices is: $ 10 - $ 7 = $ 3

So 100 each, the interest is: $ 3 X100 = $ 300 => 30%

Answer:

The rate of change of the radius of the cone when the radius is 3 inches is 0.[tex]\overline 3[/tex] inch/minute

Step-by-step explanation:

The given parameters are;

The radius of the cone = 3 inches

dV/dt = 9·π in.³/min

The height, h = 3 × Radius, r

The formula for the volume of a cone, V is V = 1/3×π×r²×h = 1/3×π×r²×3×r = π·r³

Therefore, we have;

dV/dt = dV/dr × dr/dt

dV/dr =3·π·r²

∴ dr/dt = dV/dt/(dV/dr) = 9·π/(3·π·r²) = 3/r²

When r = 3 inches, we have;

dr/dt = 3/r² = 3/(3²) = 1/3 inch/minute

The rate of change of the radius of the cone when the radius is 3 inches = 0.[tex]\overline 3[/tex] inch/minute

Answer:

The mean of T is 10 seconds

Step-by-step explanation:

The given parameters are;

The mean completion time of each step, μ = 10 seconds

The standard deviation, σ = 5 seconds

Each step is independent from the other steps

The variable that represents the total completion time for the three steps = T

We have the mean of T, [tex]\overline T[/tex], given by the combined mean as follows;

[tex]\overline T = \dfrac{n_1 \cdot \overline x_1 + n_2 \cdot \overline x_2 + n_3 \cdot \overline x_3 }{n_1 + n_2 + n_3 }[/tex]

Where;

[tex]The \ mean \ completion \ time \ for \ each \ step \ is \ \overline x_1 = \overline x_2 = \overline x_3 = 10 \ seconds[/tex]

n₁ = n₂ = n₃ = 1, each step is taken only once, we have;

[tex]\overline T = \dfrac{1 \times 10 + 1 \times 10 + 1 \times 10 }{1 + 1 + 1 } = \dfrac{30}{3} = 10 \ seconds[/tex]

Therefore, the mean of T = 10 seconds

Using the normal distribution, it is found that the mean of T is of 30 seconds.

A normal distribution has two parameters: Mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex].

In this problem, the mean is [tex]\mu = 10[/tex] and the standard deviation is [tex]\sigma = 5[/tex].

For the total completion, there are 3 instances, hence [tex]n = 3, n\mu = 3(10) = 30[/tex], hence, the mean of T is of 30 seconds.

There will be 130 nickels and 90 dimes. 100 nickels is 5 dollars. 90 dimes are 9 dollars. And then there will be 30 left. 30 dimes isn’t 1.50$ bur 30 nickels is 1.50$ so you add the 30 to the nickels and it’ll be exactly 15.50$.

Answer:

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = [tex]-\frac{5}{3}x+14[/tex]

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

Step-by-step explanation:

Step 1: Find AB Use Pythagoras Theorem

AB = [tex]\sqrt{AC^{2} -BC^{2} } = \sqrt{12^{2} -8^{2} } = \sqrt{80}[/tex]

Step 2: Find the Area of the triangle ABC

Area = [tex]\frac{1}{2}AB.BC = \frac{1}{2}\sqrt{80}.8 = 4\sqrt{80}[/tex] = [tex]16\sqrt{5}[/tex]

Step 3: Find BD. Use the area of the triangle above

Area = [tex]\frac{1}{2}BD.AC[/tex]

We already known the Area and AC so, we just plug all the number in

BD = [tex]\frac{2. Area}{AC}[/tex] =  [tex]\frac{2.16\sqrt{5}}{12}[/tex] = [tex]\frac{8\sqrt{5}}{3}[/tex]

Step 4: Find DC. Use Pythagoras Theorem of the triangle BDC

DC = [tex]\sqrt{BC^{2}-BD^{2} }[/tex] = [tex]\sqrt{8^{2}-(\frac{8\sqrt{5}}{3})^{2}}[/tex] =  [tex]\frac{16}{3}[/tex]

Answer:

No Solution.

Step-by-step explanation:

Equality equation:

— 2y – Зу +8 = 8 — 5у – 12  (Given)

-5y + 8 = -4 - 5y (distributive property of equality)

-5y = -12 - 5y (subtraction property of equality)

= -12 (addition property of equality)

when you add 5y on both sides it cancels the 5y out, it's no solution.

Step-by-step explanation:

p+9=2p-3

subtract 9 from both sides

p+9=2p-3

-9 -9

simplify

p=2p-12

subtract 2p from both sides

p=2p-12

-2 -2

simplify

-p= -12

divide both sides by -1

p=1

The dimensions of a rectangle are;

Length = 32 feet

Width = 15 feet

Here,

The length of a rectangle is 2 feet more than twice the width.

The perimeter of a rectangle is 34 feet.

What are the dimensions of the rectangle?

The two main dimensions of a rectangle are length (L) and width (W).

Now,

Let width of the rectangle is x

Then, length of rectangle is 2x + 2

The perimeter of a rectangle is 34 feet.

⇒ x + x + (2x + 2) +( 2x + 2) = 34

⇒ 6x + 4 = 34

⇒ 6x = 30

⇒x = 5

Hence, The dimensions of a rectangle are;

Length = 2x + 2 = 32 feet

Width = x = 15 feet

Answer:

Start at -1 and go down 3 right 4,repeat. Then up 3 left 4 from -1, repeat.

Step-by-step explanation:

Answer:

So start at the y intercept which is -1 in this case becuase the point slope formula goes like

y=mx+b

m= slope

b= y-intercept

Y= Ranodm Y coordinate

X= Random X coordinate

You don’t have to worry so much about the x and Y, the main focus while graphing is the slope (m) and the y-intercept (y)

So -1 is the y-intercept so you go to -1 on the graph on the Y axis, it should be right below 0.

Now to make the points, the slope is -3/4

So a slope is written rise/run

Rise is going up and run is going right

-3 is the rise

4 is the run

Since the slope is negative (due to having a negative on 1 side)

We just do the opposite for the rise

Go down 3 and go to the right 4.

There you have it

Answer:

It will cost $215 for 2 guests to rent a cabin.

Step-by-step explanation:

$175+20(2)=$215

The total for both 2 guests are $390. Each time someone rents a cabin they have to add $20 more. $175+$20+$195. So $195 will the cost for a cabin for a guest. But we need 2 cabins which means to multiply $195 with 2 which gives you $390. So both 2 guests needs $390 to rent 2 cabin.
