Consider the points (-5,2) and (3,-9)
What's the horizontal distance between the two points?
Answer:
The distance between the 2 points is about 13.6
Step-by-step explanation:
Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.
The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.
[tex]3--5=3+5=8[/tex]
The length of the other leg is the distance between the y, between 2 and -9.
[tex]-9-2=-11[/tex]
That's just a distance of 11, as there's no such thing as negative distance.
Now we have the legs, so we can find the hypotenuse:
[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]

Answer:
x y
4/3 2
8/3 10/3
22/3 24/3
Step-by-step explanation:
Substitute y with 2 for the first problem
2=x+2/3
Subtract 2/3 on both sides:
4/3
Thus:
x y
4/3 2
Now Substitute x with 8/3 for the second problem
y=8/3+2/3
Add:
y=10/3
Thus:
x y
8/3 10/3
Now Substitute x with 8/3 for the third problem
y=22/3+2/3
Add:
y=24/3
Thus:
x y
22/3 24/3
Thus the Full equation is:
x y
4/3 2
8/3 10/3
22/3 24/3
Hope this helps!
Answer:
x y
4/3 2
8/3 10/3
22/3 8
Step-by-step explanation:
y=x+2/3
2=x+2/3
2-2/3=x+2/3-2/3
6/3-2/3=x
4/3=x
y=x+2/3
y=8/3+2/3
y=10/3
y=x+2/3
y=22/3+2/3
y=24/3

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.
Part A: How much did Ron pay in sales tax? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.
Answer:
A. $2.00
B. $26.99
Step-by-step explanation:
0.5 x 49.99 = 24.995
49.99 - 24.995 = 24.995
0.08 x 24.995 = 1.9996 and round to the nearest hundredth
24.995 + 1.9996 = 26.9946
round to the nearest hundredth
Answer:
Part a: 1.9996
Part b: 26.9946
Step-by-step explanation:
STEP 1:
Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.
STEP 2:
Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).
STEP 3:
Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?
Answer: Sarah does not have enough money to purchase the TV.
Explanation: The total price is $395.91.
Answer:
No
Step-by-step explanation:
10% of 415
= 1/10 of 415
= 1/10 * 415
= $41.5
415 - 41.5 = $ 373.5
6% of 415
= 6% * 415
= $24.9
∴ $373.5 + $24.9 = $398.4
∴ Sarah cannot buy the TV as she is $ 8.4 short.
Y = 4x + 9
What is the slope and the y-intercept?
Answer:
y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
Answer:
m = 4b = 9Step-by-step explanation:
We know that:
y = mx + by = 4x + 9If we compare these two equations, we can find the slope and the y-intercept.
=> (y = mx + b) = (y = 4x + 9)
We can clearly see that 'm = 4' and 'b = 9'.
Conclusion:
Therefore:
m = 4b = 9Hoped this helped.

Which statement is modeled by the expression?
100p
A. After the league had supplied each player with a uniform, there were 100 uniforms left over. If there are p players in the league, 100p is the number of uniforms the league had originally.
B. The coach received 100 tokens for the amusement park rides. If there are p players on the team, each player will receive 100p tokens.
C. Each player in the league was given 100 tickets to sell. If there are p players in the league, the total number of tickets to sell is 100p
D. One hundred more players signed up for soccer than the league had planned for. The league had p uniforms in stock. The number of uniforms the league needs to buy to make up the difference is 100p.

Answer:
25:26
Step-by-step explanation:
You mean the ratio?
Let's simplify the speed skater first. 500 meter in 40 second to x meter in 1 second. 500/40=12.5 meters per seconds
Cheetah:260/10=26 meters per seconds
Let's make this into a integer
