Answer:
Step-by-step explanation:
Since the picture isn't given. I have no idea what the radius or diameter is and as such, have no definite answer for you.
However, from the question, if he's to run round the circular track once, then he must have run a total of
2πr meters, with r being the radius.
Now, the question says that he ran round the track 10 times, this means that whatever value we get there, for 1 trial, we multiply it by 10, to get the value for 10 trials. Essentially,
10 * 2πr
The value gotten is the needed answer. All you have to do is substitute r for the value you have in your diagram. We already know that π is 3.142

Sami was asked to solve the following system of equations using substitution.
y=6x -4
y=2x
Here is the work that sami did:
2x = 6x -4
8x = -4
x = -0.5
And then to find y: y= 2 (-0.5) = -1
so Sami's answer for the point of intersection was (-0.5, -1).
Clearly state Sami's one error and then give the correct ordered pair for where the lines cross.
Answer:
see explanation
Step-by-step explanation:
Sami's error is in the second line of working
2x = 6x - 4 ← correct substitution ( subtract 6x from both sides, Sami has added 6x )
- 4x = - 4 ← correct second line ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into the second equation
y = 2x = 2(1) = 2
solution is (1, 2 )

Fairview is 15 kilometers due north of the airport, and Lowell is due east of the airport. If the
distance between Fairview and Lowell is 17 kilometers, how far is Lowell from the airport?
Answer:
8km
Step-by-step explanation:
The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.
To find the distance between Lowell and the port which is the base use the pythagorean theorem.
=√17² - 15²
=8km

Answer:
x = 4
Step-by-step explanation:
1. Write the equation
3/4x = 2x - 5
2. Get the variables on the same side
Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!
-1.25x = -5
3. Divide both sides by -1.25
x = 4
Thank you for the points!!!

what is the slope of the line?
What is the y-intercept?
Write the equation of the line?
Answer:
The slope is 2
The y-intercept is 3
The equation is y = 2x +3
Step-by-step explanation:
The equation goes up 2 squares and over 1 square. 2/1 = 2
For y-intercept, look at the y-axis
The equation is supposed to be written as y = mx + b
m being the slope and b being the y-intercept.
Please help! You don't have to show work, just tell me the answer
Answer:
1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%
2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different
3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side
Step-by-step explanation:
What is the probability of flipping a coin 3times and getting 3tailsin a row?
Answer:
1/8
Step-by-step explanation:
The probability of getting tails on a single flip is 1/2.
Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.
So, your answer will look like this
[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;
1/8
Answer:
1/8
Step-by-step explanation:
To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as H for heads or T for tails all results of 3 flips can be written as:
Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }
Each triplet contains results on 1st, 2 nd and 3 rd coin. So you can see that in total there are 8 elementary events in Ω.
| Ω | = 8
Now we have to define event A of getting tails three times.
The only elementary event which satisfies this condition is ( T , T , T ) so we can write that:
A = { ( T, T , T ) }
| A | = 1
Now according to the (classic) definition of probability we can write, that:
P ( A ) = | A|/ | Ω | = 1 /8
So finally we can write the answer:
The Probability of getting 3 tails in 3 coin flips is 1 /8 .
Determine the area of the parallelogram.use proper units
Answer:
180 in^2
Step-by-step explanation:
to find the height you need to look at the triangle and apply pythagorean theorem
5^2=x^2=13^2
25+x^2=169
x^2=144
x=12
now we can find the area of the parallelogram:
b*h=area
15*12=180 in^2
The area of the parallelogram is 180 in^2

Zach has an above-ground pool that has a radius of 5.5 feet. He wants to put a new wall liner around his pool and needs to know the circumference of the pool. Find the circumference of the pool to the nearest hundredth.
Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.
