The measure of angle θ is 7pi/4 . The measure of its reference angle is *Blank* °, and tan θ is *blank*

sukhopar [10]

Since the measure of angle $\Theta$ is $\frac{7\Pi }{4}$

The measure of its reference angle = $\frac{7\times 180^{\circ}}{4}$

= $=315^{\circ}$

Now we have to compute the value of $\tan \Theta$

$\tan \Theta = \tan \frac{7\Pi }{4}$

$= \tan (2\Pi -\frac{\Pi }{4})$

The value of ( $(2\Pi -\frac{\Pi }{4})$ ) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.

So, $\tan (2\Pi -\frac{\Pi }{4})$

$= -\tan (\frac{\Pi }{4})$

= -1.

Selena and Ronald are planning to get married at the university where they met and graduated. The university charges $2,000 to s

jok3333 [9.3K]

Here, we have to find the number of guests who can attend their weeding without exceeding the set budget of $10,000

Since the catering fee of $150 is waived, we do not consider this figure in our analysis

There is a constant which is the venue costs of $2,000 and a variable cost of $80 per guest for the reception.

Let us assume "X" guests arrive for the reception, so we can form the equation as shown below:

80X + 2,000 = 10,000 (Since the total budget for the wedding is $10,000)

80X = 8000

8X = 800

X =100

Therefore, Selena and Ronald can invite 100 guests for the wedding without going over their budget

Tim and Jane both work for a company that sells boxes of breakfast cereal. the boxes of cereal cost £3.00 and the amount of cere

Alenkasestr [34]

Answer:

25%

Step-by-step explanation:

As the given situation the parameters are below:-

Cost of each box = 3 pounds

Amount of cereal in each box = 160 g

now,

160 g of cereal = 100%

and

25% of 1 box of cereal = 25% of 160 g which is

$= \frac{25}{100} \times 160 g= 40 g$

As per the question, it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided

160 g of cereal costs 3 pounds

and

1 g of cereal will cost

= $\frac{3}{60}\ pounds$

40 g of cereal will cost $40\times \frac{3}{160} = \frac{3}{4}\ pounds$

So, the percentage of $\frac{3}{4}$ the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100

= 25%

Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.
