Answer:
18,176
Step-by-step explanation:
Figure out an easier thing to do: 1000 - 2021 = 9,797.
Therefore, our answer will be like 9999999999999999999999997979. Out of all of these digits, there are only 2 that arent nines. We know the amount of digits since it's 10^2021 power. We will have one less since we are subtracting 2021. Therefore, 2020 digits in total. Now we know of those 2020 digits, 2 of them are 7, therefore 2018 of them are 9s. That means do 2018(9) + 2(7) = 14 + 18,162 = 18,176.
Thirty minutes before a concert, there were 1,200 people in the 3,000-seat auditorium where the concert was being held. Five minutes before the concert, the auditorium was 90% full. Which of these equations can be used to determine p, the number of people who entered the auditorium during this time interval?
Answer: p = 1500
Step-by-step explanation:
Initially, there were 1200 people.
After the given interval, we know that the auditorium is 90% full (where the auditorium can hold a maximum of 3000 people)
Then after the interval, the number of people in the auditorium is equal to the 90% of 3000.
When we have a percentage X of a quantity A, the quantity of the percentage X is:
N = (X/100%)*A
In this case, the 90% of 3000 is equal to:
N = (90%/100%)*3000 = 0.9*3000 = 2700.
Then, at the beginning of the interval there were 1200 people, and at the end there were 2700.
The difference is:
p = 2700 - 1200 = 1500
This means that the number of people who entered the auditorium dirung the time interval is 1500.

SIMPLIFY TO A SINGLE POWER OF 6:
[tex]\dfrac{6^5}{6} = \dfrac{6^5}{6^1} = 6^{5-1} = 6^4[/tex]
Answer:
6^4
Step-by-step explanation:
Since we aren't given a power in the denominator we can rewrite it as 6^1 since that equals 6 either way. Use the rule [ x^y/x^z = x^y-z ] to rewrite as a single power. Thus, 6^5-1 = 6^4.

GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e
Answer:
21°
Step-by-step explanation:
GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e
= 5x + 66 + 3x + 142 - 4x = 180
4x + 208 = 180
4x = 208 - 180
4x = 28
x = 28/4
x = 7
Solving for E = 3x
E = 3 × 7
E = 21°

50 pts and brainliest. Is the ratio of arc length to r always equal to pi? What is it equal to?
Please only answer if you know it, this is super important!! If it's right I'll mark you brainliest!
Answer:
It can sometimes be equal to π. However, it is equal to our central angle.
Step-by-step explanation:
First, recall that arc length is given by:
[tex]s=r\theta[/tex]
Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.
So, the ratio of the arc length to the radius is:
[tex]\displaystyle \frac{r\theta}{r}[/tex]
The radius r cancels. Hence, we are left with:
[tex]=\theta[/tex]
So, the ratio of the arc length to the radius does not equal π (although it can sometimes if the central angle is π radians (or 180°)). Rather, the ratio is equivalent to the central angle.
So, for example, if we have a circle with radius 7 with a central angle of 3π/2 (this gives us an arc length of 21π/2), then the ratio of the arc length to the radius will be 3π/2 (our central angle).
Answer:
Sometimes it can be equal to π. It is equal to our central angle.
Step-by-step explanation:
Recalling arc length is given by:
Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.
So, the ratio of the arc length to the radius is:
rθ/θ
The radius r cancels. Hence, we are left with:
= θ
