Answer:

30 inches

Step-by-step explanation:

She has 10 packages of yarn.

She uses 1/3 package of yarn for each inch of the scarf.

Therefore, 1 package of yarn will be 3 times each inch:

3 * 1 = 3 inches

1 package of yarn goes for 3 inches of scarf.

Therefore, 10 packages will go for:

10 * 3 = 30 inches

Answer:

When the truck is full: [tex]g_{mf} = \frac{m}{8}[/tex]

When the truck is empty: [tex]g_{me} = \frac{m}{9.6}[/tex]

Step-by-step explanation:

When the truck is full for every eight miles traveled by the vehicle, there is a cost of one gallon of fuel, therefore for every mile the cost is one eight of a gallon, with this information we can create the following expression:

[tex]g_{mf} = \frac{m}{8}[/tex]

Where m is the number of miles traveled by the truck.

When the vehicle is empty, it's performance improves by 20 %, which means that for the same amount of fuel it'll travel a distance 120% of the previous one. Therefore we need to multiply 1.2 on the denominator of the last expression:

[tex]g_{me} = \frac{m}{8*1.2}\\\\g_{me} = \frac{m}{9.6}[/tex]

The expression represents the amount of gasoline used (g) is,

When the truck is full (mf) is represented as [tex]m_f = \dfrac{m}{8}[/tex],

And when the truck is empty (me) is represented as,  [tex]m_e = \dfrac{m}{9.6}[/tex]

Given that,

A long-distance delivery truck averages 8 miles per gallon when the truck is full.

The miles per gallon improve by 20% when the truck is empty.

We have to determine,

Which expression represents the amount of gasoline used (g) in terms of the number of miles driven when full (mf) and the number of miles driven when empty (me).

According to the question,

The amount of gasoline used (g) in terms of the number of miles driven when full (mf),

And The distance delivery truck averages 8 miles per gallon when the truck is full.

The amount of gasoline when the truck is full is represented as,

[tex]m_f = \dfrac{m}{8}[/tex]

Then,

The miles per gallon improve by 20% when the truck is empty.

The number of miles driven when empty is represented as,

[tex]m_e = \dfrac{m}{8 + 8 \times 0.20}\\\\m_e = \dfrac{m}{8+ 1.6}\\\\m_e = \dfrac{m}{9.6}[/tex]

Hence, The expression represents the amount of gasoline used (g) is,

When the truck is full (mf) is represented as [tex]m_f = \dfrac{m}{8}[/tex],

And when the truck is empty (me) is represented as,  [tex]m_e = \dfrac{m}{9.6}[/tex].

Answer:

Step-by-step explanation:

Let's take each one of those answers and test it against the graph.

"Greater app price always relates to greater profit."

***As you can see, this is not true. Although the profit does increase up to a point as the app price increases, look at the profit at an app price of $4 and an app price of $11. The profit from a $4 app is about $30 million and the profit from the $11 app is about $24 million.

"Greater app price relates to greater profit as long as the app's price is more than about $7."

***As we just saw in the above statement, this is not true.

"The largest possible profits the company can make is 7 million dollars."

***The highest profit is where the highest point on the graph is. While the APP price is $7 at this highest point, the profit there is about 39 million dollars. So the largest possible profit is not 7 million, the largest profit corresponds to an app price of $7 with a profit of 39 million.

"The largest possible profit the company can make is about 40 million dollars."

***From above, we know that this is true.

The only true statement is the last one.

Answer:

E67.5

Step-by-step explanation:

Answer: a. 36-17 <0.04x ⇒ 475 < x

b. When the number of calls is higher than 475 , Plan 1 is more economical than Plan 2.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The cost of plan 1 (36) must be less (<) than the cost of plan 2 (fixed charge [17] plus the product of the charge per call [0.04] and the number of calls [x] )

a.36 < 17+ 0.04x

Solving for x

36-17 <0.04x

19 < 0.04x

19 /0.04 <x

475 < x

b. When the number of calls is higher than 475 , Plan 1 is more economical than Plan 2.

Answer:

c = 3/4

Step-by-step explanation:

Lets set up an equation.

You can get

3-5c + 1 = 1-c to show that it is one less.

now we can solve it.

So by combining like terms, we get:

4-5c = 1-c

that then becomes:

3-5c = -c

--> 3 = 4c

--> c = 3/4

Answer:

Width of screen =57.44 cm

Step-by-step explanation:

Please refer to the attached image:

The TV screen is usually in the form of a rectangle.

The diagonal of the TV is termed as the screen size.

Size is given to be 70 cm

Height = 40 cm

As per the attached image:

BC = 40 cm

BD = 70 cm

Pythagoras theorem is given as:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Height}^{2}[/tex]

Using pythagoras theorem in [tex]\triangle BDC[/tex]:

[tex]BD^{2}= BC^{2}+ CD^{2}[/tex]

[tex]70^{2}= 40^{2}+ CD^{2}\\\Rightarrow CD^{2} =4900 - 1600\\\Rightarrow CD^{2} =3300\\\Rightarrow CD =57.44 cm[/tex]

Hence, width of screen, CD =57.44 cm

Answer:

m∠BCD = 82°

Option A

Step-by-step explanation:

The opposite angles of quadrilateral inscribed in a circle are supplementary.

i.e m∠A +m∠C = 180°

or, m∠BAD + m∠BCD= 180°

or, 98° + m∠BCD = 180°

or, m∠BCD = 180°-98°

or,m∠BCD = 82°

Answer: A - 82

Step-by-step explanation:

 180 - 98 = 82

Answer:

1/9

Step-by-step explanation:

4 green marbles, 5 red marbles, and 6 blue marbles in a bag = 15 marbles

P(red)= number of red/ total = 5/15 = 1/3

Put it back in the bag

4 green marbles, 5 red marbles, and 6 blue marbles in a bag = 15 marbles

P (red)= number of red/ total = 5/15 = 1/3

P(red, replace, red) = P(red) * P(red) = 1/3*1/3 = 1/9

C = √269

C ≈ 16.4

Step-by-step explanation:

Use the Pythagorean Theorem to solve for 'c'.

[tex]a^2+b^2=c^2[/tex]

We are given:

'a' = 13

'b' = 10

Replace the variables with the appropriate values and solve for 'c':

[tex]13^2+10^2=c^2\\\rightarrow 13^2=169\\\rightarrow 10^2=100\\169+100=c^2\\269=c^2\\\sqrt{269}=\sqrt{c^2}\\\boxed {16.40122... = c}[/tex]

16.4012195 ≈ 16.4

C is about 16.4.

sin150° = sin30° = [tex]\frac{1}{2}[/tex]

Given

z = 4(cos150° + isin150° ) , substitute values

  = 4(- [tex]\frac{\sqrt{3} }{2}[/tex] +  [tex]\frac{1}{2}[/tex]i )

  = - 2[tex]\sqrt{3}[/tex] + 2i , that is

(- 2[tex]\sqrt{3}[/tex], 2 ) → B

Answer:

option (c) [tex]\{-1,\dfrac{4}{3}\}[/tex]  is the correct answer.

Step-by-step explanation:

The given Quadratic equation is:

[tex]3x^{2} -x-4=0[/tex]

Let us try to make factors:

[tex]3x^{2} -x-4=0[/tex]

Here, [tex]-x[/tex] can be written as [tex]-4x + 3x[/tex] (Look at the coefficient of [tex]x^{2}[/tex] and constant part i.e. 3 and 4). So, the quadratic equation becomes:

[tex]\Rightarrow 3x^{2} -4x+3x-4=0\\\text{Taking x common from }3x^{2} -4x \text{ and 1 common from }3x+4:\\\Rightarrow x(3x-4)+1(3x-4)=0\\\Rightarrow (x+1)(3x-4)=0\\\Rightarrow (x+1) =0\ or\ (3x-4) = 0\\\Rightarrow x =-1\ or\ x = \dfrac{4}{3}[/tex]

So, solution set for the equation [tex]3x^{2} -x-4=0[/tex] is:

[tex]\{-1,\dfrac{4}{3}\}[/tex]

Hence, option (c) [tex]\{-1,\dfrac{4}{3}\}[/tex]  is the correct answer.

Answer:

The slope is 10 (y =10x +15)

Step-by-step explanation:

When using two coordinates to find the slope of a linear function, I choose (-2,-5) and (2,35) *but you can choose any two.

The formula for finding the slope is y-y divided by x-x.

so... (35)-(-5)=40        NOTE: I did 35 minus -5 but you can also do -5 minus 35.

2-(-2)=4                           But just remember to do it the same order for

                                    subtracting the x coordinates.

Answer:

729 cubic meters

Step-by-step explanation:

Volume of cube is given by side^3

where side is length of the side

Given in the problem

side is 9 meters as length, width, and height of fort is 9 meters and it is in cube shape .

Thus,

volume of cube = 9^3 = 9*9*9 = 729

Thus, volume of Haley's fort is 729 cubic meters.
