A plane flew 390 nautical miles in 45 min. Find its average speed in knots ( nautical miles per hour)
Answer:
451.87 knots.
Step-by-step explanation:
Hope this helps
The average speed of the plane is 520 Knots.
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: Distance travelled 390 nautical miles and t is 45 mins or 0.75 hours
Thus speed of the plane is = 390/0.75
= 520
Hence, The average speed of the plane is 520 Knots.

Help me out here!! Please!
my mom homeschools me and she has this thing called desmos so I'm trying to figure this out
Answer:
250 gallons of water are being pumped out each hour
Step-by-step explanation:
It tells us that W is the amount of water in the pool at a time. It also tells us that at the start there is 9000 gallons in the pool. We also know t is the time in hours so 1 t = 1 hour.
W=9000-250t
We can substitute in what we know
The amount of water in the pool = 9000 gallons - 250 gallons times 1 hour
so that means if one hour passes 250 gallons are removed, and if 2 pass then 500 are removed showing that for every hour the pump is on 250 gallons of water are being sucked from the pool

10,000−99,999<0
34-43=0
(30)(-80)−50=50−(30)(-80)
Answer:
Below
Step-by-step explanation:
False, negative times negative is always positive.
True, 10,000 is less than 99,999, so subtracting them will be negative.
False, 34 and 43 aren't equal to eachother so subtracting them can't end up to 0.
False. If you follow PEMDAS, you have to do multiplication first. In the left side, -80(30) is a negative value, while in the right, (-30)(-80) is a positive value.

It's D, 15!/(15 - 5)! .
15! is the number of ways of permuting 15 objects. In other words, if you have 15 open positions,
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _
from the 15 total objects you can pick, there are 15 choices for the first position, 14 for the second, 13 for the third, and so on, so that there is a total of
15 * 14 * 13 * … * 2 * 1 = 15!
possible arrangements.
But you're taking 5 objects at a time, so we only have 5 positions to fill:
_ _ _ _ _
and there are 15 choices for the first position, 14 for the second, 13 for the third, 12 for the fourth, and 11 for the fifth, so the total number of arrangements is
15 * 14 * 13 * 12 * 11 = 15!/10! = 15!/(15 - 5)!

The solutions to the quadratic equation 5x² - 7x - 18 = 0 are [tex]\frac{7-\sqrt{ 409} }{10} \ and \ \frac{7+\sqrt{ 409} }{10}[/tex].
What are the solutions to the quadratic equation?Given the quadratic equation in the question:
5x² - 7x - 18 = 0
Compared to the standard form ax² + bx + c = 0:
a = 5, b = -7 and c = -18
To find the solutions to the quadratic equation, we use the quadratic formula:
[tex]x = \frac{-b\±\sqrt{b^2 - 4(ac)} }{2a}[/tex]
Plug in the values and simplify:
[tex]x = \frac{-(-7)\±\sqrt{(-7)^2 - 4(5*-18)} }{2*5} \\\\x = \frac{7\±\sqrt{( 49 +360)} }{10} \\\\x = \frac{7\±\sqrt{ 409} }{10} \\\\x = \frac{7-\sqrt{ 409} }{10}, \frac{7+\sqrt{ 409} }{10}[/tex]
Therefore, the values of x are [tex]\frac{7-\sqrt{ 409} }{10} \ and \ \frac{7+\sqrt{ 409} }{10}[/tex].

7+6-9(-2)+(-3) simplify step by step plzzzx
=13+18-3
=31-3
=28
the answer is 28
Answer:
28
Step-by-step explanation:
According to Order of Operations rules, we must multiply here before adding or subtracting.
In 7 +6 - 9(-2) + (-3) the very first thing we must do is to evaluate the product -9(-2). This comes out to 18, so now we have:
7+6 + 18 +(-3).
Next, remove the remaining parentheses, obtaining:
7 + 6 + 18 - 3, or
13 + 15 = 28

50 Benson purchased a $1,800 certificate of deposit that earns s
of 1 year, the certificate was worth $1,857.60.
What is the annual interest rate on this certificate of deposit
Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%
