Answer:
20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
WOW, that's a lot of points!!
To find the answer for this problem, you take 80% of 50.
In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Can someone answer this im so lost
Step-by-step explanation:
The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.
Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.
This can be represented by -2x because the word "melts" indicates a negative value.
From this, the equation can be made :)
2. Solve: 2p+4= - 50
2p + 4= -50
=> 2p = -50-4
=> 2p = -54
=> p = -54/2
=> p = -27
Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

Kahleela starts the engine on her small private airplane. The engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. At idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. The height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. Find h when t = 5.5 minutes.
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

Solve each system by elimination. 3x - 2y = 1 2x + 2 y = 14
Determine whether the lines are parallel, perpendicular, or neither.
y = 3x - 2
-3x + y = 8
Answer:
they are parallels
Step-by-step explanation:
they have the same slope but different y intercepts so they are parallel
Answer:
Parallel
Step-by-step explanation:
First, you should put the second equation in slope-intercept form, it would be y=3x+8.
If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

-4x+5 + -13x+39=180 angle measure
Step-by-step explanation:
−4x+5−13x+39=180
Step 1: Simplify both sides of the equation.
−4x+5−13x+39=180
−4x+5+−13x+39=180
(−4x+−13x)+(5+39)=180(Combine Like Terms)
−17x+44=180
−17x+44=180
Step 2: Subtract 44 from both sides.
−17x+44−44=180−44
−17x=136
Step 3: Divide both sides by -17.−17x
−17

A store down the street is selling a console 50% of from 236.87 if i were to buy the console wit my 490.45 how much money will i get back?
Answer:
$372.01
Step-by-step explanation:
50% of $236.87 is half of it, which means the console is being sold for $118.44 because:
235.87/2 = 118.435
Round this to the nearest cent:
$118.44
If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:
490.45 - 118.44 = 372.01
You will have $372.01 left.

the average screen time for middle school students is 240 minutes per day. In 2020 students went into virtual learning and the average screen time is 70 percent longer. What is the total percent of screen time this year?
Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)
