Answer:

Part 1) [tex]a=-\frac{1}{4c^6}[/tex]

Part 2) [tex]a=-\frac{1}{4c^{-6}}[/tex]

Step-by-step explanation:

Part 1) we have

[tex]a=2b^{3}[/tex] ----> equation A

[tex]b=-\frac{1}{2}c^{-2}[/tex] ----> equation B

substitute equation B in equation A

[tex]a=2(-\frac{1}{2}c^{-2})^{3}[/tex]

Applying property of exponents

[tex](x^{m})^{n}=x^{m*n}[/tex]

[tex]x^{-m} =\frac{1}{x^{m}}[/tex]

[tex]a=2(-\frac{1}{2}c^{-2})^{3}=2(-\frac{1}{2})^3(c^{-2})^{3}=2(-\frac{1}{8})(c^{-6})=-\frac{1}{4c^6}[/tex]

therefore

[tex]a=-\frac{1}{4c^6}[/tex]

Part 2) we have

[tex]a=2b^{3}[/tex] ----> equation A

[tex]b=-\frac{1}{2c^{-2}}=-\frac{c^{2}}{2}[/tex] ----> equation B

substitute equation B in equation A

[tex]a=2(-\frac{c^{2}}{2})^{3}[/tex]

Applying property of exponents

[tex](x^{m})^{n}=x^{m*n}[/tex]

[tex]x^{-m} =\frac{1}{x^{m}}[/tex]

[tex]a=2(-\frac{c^{2}}{2})^{3}=2(-\frac{c^{6}}{8})[/tex]

simplify

[tex]a=-\frac{c^{6}}{4}[/tex]

therefore

[tex]a=-\frac{1}{4c^{-6}}[/tex]

Answer:

$153.75

Step-by-step explanation:

$71.75 / 7=$10.25

$10.25 x 15 =$153.75

I believe it's a 25% profit.

950+250= 1200

1500-1200= 300

300/1200= 0.25

0.25 x 100= 25%

Answer:

I want to say 20% I could be wrong

Step-by-step explanation:

$950 + $250 = 1,200

1,200 ÷ 1500 = 0.8

0.800 > 80.0

80%

100% - 80% = 20%

Net Profit Margin = 20%

Net Profit =$300

Profit Percentage = 25%

Answer:

Perpendicular

Step-by-step explanation:

Put all the points on a graph.

Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.

On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.

Answer:[tex]\frac{1}{12}[/tex]

Step-by-step explanation:

Okay, first, you want to find the probability of getting a head, which would be 1/2 because there are two options and we are only looking for one out of the two. Then, the probability of getting a 6 would be 1/6 because there is only one chance of getting a 6 and there are 6 options. Next, you would have to multiply both quantities to find out what the probability would be of getting both. So it would be [tex]\frac{1}{2}[/tex] ×[tex]\frac{1}{6}[/tex]=[tex]\frac{1}{12}[/tex]

Probability of getting a head followed by a 6 is 1/12

Step-by-step explanation:

There are 2 possible outcomes of tossing a coin a head and a tail.

The probability is 1 out of 2 each for head and tail.

Probability of getting a 6 when a dice is rolled is 1 out of 6 for each face i.e 1,2,3,4,5,6

So the probability of getting a head followed by 6 is 1/2*1/6 = 1/12

It can also be understood as below.

There can be 12 possible combinations once a coin is tossed and a die is rolled. Head-1, Head-2. Head-3, Head-4, Head-5, Head-6, Tail-1, Tail-2, Tail-3, Tail-4, Tail-5, Tail-6

In the list there is 1 outcome that we need. Head-6. This again gives us the chance of getting Head-6 as 1 out of 12.

Answer:

12 choices

Step-by-step explanation:

2*3 = 6

6*2= 12

You would have to multiply the numbers to see the number of choices.

There are 12 different choices for coffee in the shop.

First, we need to find the selections, these are:

Now we need to find the number of options for each selection:

Answer:6

Step-by-step explanation:

Answer:

Kira served 25 orders, Bill served 34 orders and Michael served 75 orders.

Step-by-step explanation:

Let Kira served x number of orders.

So, Bill served (x + 9) orders and Michael served 3x orders.

Now, it is given that Kira, Bill, and Michael served a total of 134 orders.

So, x + (x + 9) + 3x = 134

⇒ 5x + 9 = 134

⇒ 5x = 125

⇒ x = 25

Therefore, Kira served 25 orders, Bill served (25 + 9) = 34 orders and Michael served 3 × 25 = 75 orders. (Answer)

Answer:

43.5 ft

Step-by-step explanation:

Given: Julie is 6 feet tall

           She stands 15 feet from the flagpole.

           The edges of the square line up with the top and bottom of the flagpole.

Picture drawn to show side and angle formed by Julie and flagpole.

Lets assume the height of flagpole be "h".

As given, the edges of the square line up with the top and bottom of the flagpole.

∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.

Now, finding the height of flagpole by using tangent rule.

we know, [tex]tan\theta= \frac{Opposite}{adjacent}[/tex]

Remember, both the angle are equal.

∴ Ratio of opposite and adjacent leg for both right angle triangle= [tex]\frac{6}{15} : \frac{h-6}{15}[/tex]

We can put it; [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Solving the equation now

⇒ [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Multiplying both side by 15

⇒[tex]6 = \frac{15\times 15}{h-6}[/tex]

Multiplying both side by (h-6)

⇒ [tex]6\times (h-6) = 15\times 15[/tex]

Distributive property of multiplication

⇒ [tex]6h-36= 225[/tex]

Adding both side by 36

⇒[tex]6h= 225+36[/tex]

Dividing both side by 6

⇒[tex]h= \frac{261}{6}[/tex]

∴ [tex]h= 43.5\ feet[/tex]

Hence, the height of flagpole is 43.5 feet.

The height of the flagpole is given by the length of the hypotenuse side

formed by the right triangle Julie forms with the cardboard.

Response:

The triangle formed by the edges of square lined up with the top and

bottom of the flagpole is a right triangle.

The altitude of the right triangle formed with the height of the flagpole as the base = 15 feet

Length of a leg of the right triangle = √(15² + 6²) = 3·√(29)

The other angle formed by the right triangle = (90° - arctan(15/6))

h × sin(arctan(15/6)) = 3·√29

[tex]h = \mathbf{\dfrac{3 \cdot \sqrt{29} }{sin(arctan(15/6))} } = 17.4[/tex]

Height of the flagpole, h = 17.4 feet

Final answer:

The customer would need to have 25 small gifts to wrap in order for the costs to be the same, whether using the department store's service at $2 per gift or paying his niece the $50 flat fee.

Explanation:

To determine how many small gifts need to be wrapped to make the cost the same whether paying his niece the flat fee of $50 or paying the department store $2 per gift, we can set up a simple equation:

Let x represent the number of small gifts.
Then, the cost of wrapping at the department store is $2 per gift, which means the cost is 2x dollars.
The niece's flat fee is $50, regardless of the number of gifts.

The equation to find the breakeven point where both options cost the same is:
2x = 50

Solving for x gives us:

x = 50 / 2
x = 25 gifts

Thus, if the customer has 25 small gifts to wrap, it would cost the same to have them wrapped by his niece at a flat rate or by the department store per gift.

Answer:

X=40 degrees

Step-by-step explanation:

Having trouble with RSM?

The value of angle x will be equal to 40 degrees.

According to the equivalent angle postulate, if a transversal meets two parallel lines, the corresponding angles must be congruent.

In other words, the corresponding angles will always be identical if a transversal intersects two parallel lines. In geometry, corresponding sides and corresponding angles of polygons are compared as part of the tests for congruence and resemblance.

In the diagram attached with the answer below apply the corresponding angle theorem to calculate the value of x.

The value of angle x by using corresponding angle theorem will be calculated as below:-

x = 180 - 65 - 75

x = 180 - 140

x = 40

Therefore, the value of angle x will be equal to 40 degrees.
