Answer:
d) [tex]\frac{9\pi }{4}[/tex]
Step-by-step explanation:
[tex]\frac{9\pi }{4} = 2\pi + \frac{\pi }{4}[/tex]
The correct options are a and d because -7pi/4 and 9pi/4 are the required angles.
Important infromation:
The given angle is [tex]\dfrac{\pi}{4}[/tex].Angles:The angles [tex]\theta\pm 2n\pi [/tex] represent the same point on the unit circle as [tex]\theta[/tex].
It means, [tex]\dfrac{\pi}{4}\pm 2n\pi [/tex] represents the same point on the unit circle as [tex]\dfrac{\pi}{4}[/tex].
The required angles are:
[tex]\left\{...,\dfrac{\pi}{4}-4\pi,\dfrac{\pi}{4}-2\pi, \dfrac{\pi}{4},\dfrac{\pi}{4}+2\pi,\dfrac{\pi}{4}+4\pi,...\right\}[/tex]
[tex]\left\{...,-\dfrac{15\pi}{4},-\dfrac{7\pi}{4}, \dfrac{\pi}{4},\dfrac{9\pi}{4},\dfrac{17\pi}{4},...\right\}[/tex]
Therefore, the correct options are a and d.

A mattress store is having a sale all mattresses are 30% of. Nate wants to know the sale price of a mattress that is regularly $1,000
Answers
Answer: $700
Step-by-step explanation:
The store is selling at 30% off.
If a mattress is $1,000, first find out what 30% of $1,000 is:
= 1,000 * 30%
= $300
The store is selling 30% off, this means that they are reducing the price by 30%:
= 1,000 - 300
= $700

At a larger pizza party, there are 18 people. Each person wants 3 slices, and each pizza has 8 slices. How many pizzas should they order?
Answers
Answer:
7 pizzas
Step-by-step explanation:
18 people × 3 slices each = 54 slices
54 ÷ 8 = 6.75
7 pizzas
Answer:
They should order 7 pizzas.
Step-by-step explanation:
18 people x 3 slices per person = 54 slices you will need for everyone
54 slices divided by 8 = 6.75 pizzas.
Round 6.75 to 7 pizzas.
They should order 7 pizzas because you cannot ask the pizza place for 6.75 pizzas.

The circumference of the circular base of the object is 4.082 in
What is circumference?The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center.
Given that, we need to find the circumference of the circular base of the object, whose radius is 0.5 in
The circular object is referred as circle, the circle's circumference is its boundary length measured in unit whose power is always 1, like m, cm, km etc.
Here, if we calculate the circumference of the object, we will get,
The circumference of any circular object given by :-
C = 2π×radius
C = 2×3.14×0.65 = 4.082 in
Hence, the circumference of the circular base of the object is 4.082 in

Please help!! Thank you !!
Answers
Answer:
55 degrees
Step-by-step explanation:
Angle ACE and BDE are congruent so segments AC and BD are parallel. That makes angles CAE and DBE congruent.
6x - 15 = 5x - 1
x - 15 = -1
x = 14
So, the measure of angle BDE = 4x = 56 degrees. The measure of angle DBE = 5x - 1 = 69 degrees.
The total of all angles in triangle BDE is 180 degrees, so the measure of angle E = 180 - 56 - 69 = 55
