Step-by-step explanation:
The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°
Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

you estimate a lion weighs 250 pounds. the actual weight of the lion is 320 pounds. find the percent error. round your answer to the nearest tenth of a percent.
Answer:
21.9%
Step-by-step explanation:
Percent error = amount of error/actual amount
320 - 250 = 70
70/320 (division) = 0.21875
percent = 21.875%
Rounding to nearest tenth = 21.9%

A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 S
Complete Question:
A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 Seconds.
a. what acceleration is imparted to the paper?
b. if the mass of the paper is 0.003 kg, what force does the boxer exert on it?
c. how much force does the paper exert on the boxer?
Answer:
a. Acceleration = 454.55m/s².
b. Force = 1.36N
c. Force = -1.36N
Step-by-step explanation:
Given the following data;
Final velocity = 20m/s
Time = 0.044 seconds.
Since the paper is at rest, we know that it's initial velocity is equal to 0m/s.
a. To find acceleration;
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Substituting into the equation, we have;
[tex]a = \frac{20 - 0}{0.044}[/tex]
[tex]a = \frac{20}{0.044}[/tex]
Acceleration = 454.55m/s²
b. To find the force exerted by the boxer;
Mass = 0.003kg
Force = mass * acceleration
Force = 0.003 * 454.55
Force = 1.36N
c. To find the force exerted by the paper;
According to Newton's third law of motion which states that, for every action there is an equal and opposite reaction. Therefore, the paper exerts an equal but opposite force on the boxer.
Force = -1.36N

Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above
sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who
has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
meters
b. How far is Scottie from the fish?
Answer:
30 m ;
15 m ;
0 m;
40 m
Step-by-step explanation:
Scottie's position = standing on cliff
Height of cliff = 30 m above sea level
Height of lighthouse = 15 meters
Position of fish = 10m below sea level
Above sea level = positive, +
Below sea level = negative, -
Scottie's position = 30 m
Top of lighthouse = 15m
BOAT = surface of sea = 0m
Fish = - 10 m
Distance of Scottie from fish :
Scottie's position - Position of fish
30m - (-10)m
30m + 10m
= 40m

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why?
(6, 20), because the point does not lie on any axis
(6, 20), because both lines pass through this point
(3, 11), because one of the lines passes through this point
(3, 11), because the point lies between the two axes
Answer:
(6,20) because both lines pass through this point
Step-by-step explanation:
To solve this you can use the substitution method.
Since both of them are equal to y, substitute one of the equations for y, that way you have x+14 = 3x+2. From here you continue to simplify.
Eliminate x from either side of the equation. For example, subtract x from the side that says "x+14". (Make sure you are also subtracting it from the other side of the equal sign as well.
Once you do this you should now have 14 = 2x+2
In order continue, you now have to get x by itself. So now subtract 2 from both sides of the equation. After doing this, you should have 12 = 2x
You then simplify x by dividing both sides by 2. This will get you x = 6
Now that you have the x-value, substitute that into either of the two equations (it is recommended you substitute it into both equations to make sure you have the correct x-value). For example: If I substitute x into Line C's equation, I will now have y = 6 + 14.
6 + 14 is 20, therefore you're y-value is y = 20
A bag contains 7 milk and 5 dark chocolates. A sweet is selected at random. What is the probability of choosing: P(milk) = P(not milk) =
Answer: P(7)=P(5)=12
Step-by-step explanation:
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.
The total number of the sweets will be given as,
Total events = 7 + 5 = 12
The probability of choosing milk will be given as,
P = (7/12)
P = 0.5833
The probability of choosing not to milk will be given as,
P = (5/12)
P = 0.4167
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

Answer:

Step-by-step explanation:
Use ratios:
[tex]\frac{5}{8} = \frac{x}{32}[/tex]
Solve for x
x = 20
Answer:
x = 20
Step-by-step explanation:
Let’s think about it this way ( i’m gonna make this as easy as possible! )
So, x is the variable, which it represents the height of the tree right? so you’re gonna want to take the shadow of the alien, and think “well can 8 make 32? and if so how many times?” which would be 8y = 32. and yes you can. so let’s think about that. how many times does it take for 8 to get to 32?
8, 16, 24, 32
so it takes 4 times. then you think “ well if 8x4 got the shadow length, 5x4 must get the tree height” which is correct.
you’ll take 5 x 4 which is 20, and you will put that down as the heigh of the tree, or think 20ft.
so x = 20.

Answer:
9. x = 7, y = 10
Step-by-step explanation:
9. I first set up an equation x+y=17
then I set up a second equation y = x+3
I substitute y for x+3 and get x+x+3=17 or 2x+3=17
then I just evaluate the equation x=7
I then use my first equation x+y = 17 and substitute the value 7+y= 17 and get y = 10
10. Just divide 156.25 with 6.25 to get the number of hours she had to work to get 156.25 dollars. The answer would be 156.25/ 6.25 = 25

7(x-4)=4x+5 whats X?
Answer:
x = 11
Step-by-step explanation:
In this question, you would solve for x.
Solve for x:
7(x - 4) = 4x + 5
Use the distributive property.
7x - 28 = 4x + 5
Subtract both sides by 4x.
3x - 28 = 5
Add 28 to both sides.
3x = 33
Divide both sides by 3.
x = 11
Your final answer would be x = 11
Answer:
x=11
Step-by-step explanation:
First, do the parentheses (PEMDAS).
7(x-4)=4x+5 to 7x-28=4x+5
Then, add 28 to either side to get all the numbers on one side.
7x-28=4x+5 to 7x=4x+33
After that, subtract 4x to get all the x's on one side.
7x=4x+33 to 3x=33
Finally, divide by 3 to get your final answer.
3x=33 to x=11

3pts 7.) Clare is cycling at a speed of 12 miles per hour. If she starts at a position chosen as zero, what will her position be after 45 minutes?
9514 1404 393
Answer:
9 miles
Step-by-step explanation:
Of course, 45 min = 45/60 hours = 3/4 hours.
__
The relationship between time, speed, and distance is ...
distance = speed · time
distance = (12 mi/h) · (3/4 h) = 9 mi
Her position will be 9 miles from 0 after 3/4 hour.
