I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked
Answer:
35 feet
Step-by-step explanation:
We'll begin by calculating the resultant for you and your friend.
For you:
R² = 12² + 9²
R² = 144 + 81
R² = 225
Take the square root of both side
R = √225
R = 15 feet
For your friend:
R² = 16² + 12²
R² = 256 + 144
R² = 400
Take the square root of both side
R = √400
R = 20 feet
Finally, we shall determine the distance between you and your friend.
The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e
You resultant = 15 feet
Your friend's resultant = 20 feet
Distance between you and your friend = 15 + 20 = 35 feet.
Therefore, you threw the baseball 35 feet away from your friend.

what is the measure of angle b
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
b = 34 degrees
Step-by-step explanation:
*triangles have an interior angle of 180 degrees
to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:
⇒ 180 - (115 + 31)
solve:
⇒ 180 - 146 = 34
b = 34

Ivy is in Las Vegas and bet on her favorite team, the Denver Dragons, to beat the Seattle Sea Turtles. If the Denver Dragons win, she will win 10 dollars. If the Seattle Sea Turtles win, she will lose 11 dollars (the extra dollar is commission). Ivy estimates that there is a 50% chance of the Denver Dragons winning (there cannot be a tie). Find the expected return of placing this bet.
Answer: -0.5
Step-by-step explanation:
5 + (-5.5) = -0.5 dollars
The expected return of placing this bet is -0.5 dollars.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.
To calculate the expected return of this bet, we need to consider the possible outcomes and their probabilities. There are two possible outcomes:
The Denver Dragons win with a probability of 0.5. In this case, Ivy will win 10 dollars.
The Seattle Sea Turtles win with a probability of 0.5. In this case, Ivy will lose 11 dollars.
To calculate the expected return, we multiply each outcome by its probability and sum the results.
Expected return = (0.5 x 10) + (0.5 x -11)
Expected return = 5 - 5.5
Expected return = -0.5
Therefore, the expected return of placing this bet is -0.5 dollars, which means that over the long run, Ivy can expect to lose an average of 50 cents every time she places this bet.

Answer:
x=2 y=−1 so (2,-1)
Step-by-step explanation:
2x+y=3
x=3y+5
Consider the second equation. Subtract 3y from both sides.
x−3y=5
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the results for that variable in the other equation.
2x+y=3,x−3y=5
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
2x+y=3
Subtract y from both sides of the equation.
2x=−y+3
Divide both sides by 2.
x=1/2(−y+3)
Multiply 1/2 times −y+3.
x=−1/2y+3/2
Substitute y+3/2 for x in the other equation, x−3y=5.
−1/2y+3/2−3y=5
Add −y/2 to −3y.
−7/2y+3/2=5
Subtract 3/2 from both sides of the equation.
−7/2y=7/2
Divide both sides of the equation by −7/2, which is the same as multiplying both sides by the reciprocal of the fraction.
y=−1
Substitute −1 for y in x=−1/2y+3/2. Because the resulting equation contains only one variable, you can solve for x directly.
x=−1/2(−1)+3/2
Multiply −1/2 times −1.
x=1+3/2
Add 3/2 to 1/2 by finding a common denominator and adding numerators. Then reduce the fraction to the lowest terms if possible.
x=2
The system is now solved.
x=2,y=−1

The graph below models the changes in temperature of a liquid during a laboratory experiment what point of the graph represents the final temperature?
Answer:
J
Step-by-step explanation:
Since the final tempurature means the final point of the line, you can see the point that ends is on (7, 0). The order for coordinate points is (x, y) and the point ends on 7 on the x-axis and 0 on the y-axis. Hope this helped!
Tell whether the ordered pair is a solution of the equation. y = x - 5; (6, 11)
Answer:
Not a solution
Step-by-step explanation:
y=x-5
Plug in the point (6,11)
11=6-5
11=1
11≠1
Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.
I hope this helps!
Answer:
It isn't a solution of the equation.
Step-by-step explanation:
(x, y) = (6, 11)
You replace the values ok the equation:
11=6-5
11=1 Which is FALSE so it isn't a solution of the equation.

A triangular pyramid has the base of 6 ft and the hight of 9 ft what is the total surface area ?
Answer:
117 ft²
Step-by-step explanation:
Surface area of triangular pyramid = base area + ½(Perimeter of base * slant height)
Base area = ½*b*h = ½*9*6 = 27 ft²
Slant height = √(6² + 4.5²) = 7.5 ft (pythagorean theorem)
Perimeter = 7.5 + 7.5 + 9 = 24 ft
Plug in the values into the formula for surface area
Surface area = 27 + ½(24 * 7.5) = 117 ft²

Jaylen's bed is six feet long and his desk is three feet long. He wants to leave a two-foot space between his bed and desk. If there are 125 inches available along the wall, is there enough room for Jaylen to fit his bed and desk? Justify your reasoning using words, numbers, or pictures.
Answer: Not possible
Step-by-step explanation:
Given
The length of Jaylen's bed is [tex]6\ ft\approx 72\ in.[/tex]
The length of his desk is [tex]3\ ft\approx 36\ in.[/tex]
The total length along the wall is [tex]125\ in.[/tex]
Jaylen wants [tex]2\ ft \approx 24\ in.[/tex] gap between bed and desk
the combined length of bed and desk is
[tex]\Rightarrow 72+36=108\ in.[/tex]
The remaining length after placing the bed and desk is
[tex]\Rightarrow 125-108=17\ in.[/tex]
As the remaining length is less than the required length
Therefore, it is not possible to leave a gap of two-foot between the bed and desk

Find the value of x.
Answer:
80°
Step-by-step explanation:
42° + 58° + x = 180° [Angle sum property of triangle]
=> 100 + x = 180
=> x = 180 - 100
=> x = 80 (Ans)
Step-by-step explanation:
58° + 42° + x = 180° -- (Δ sum property)
100° + x = 180°
x = 180° - 100°
x = 80°

Find value of y
Answer:
Step-by-step explanation:
use SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
then we know the adjacent side and the angle, and want to find the Hyp, so use CAH
Cos(60) = ( 8[tex]\sqrt{3}[/tex] / 3 ) / Hyp ( cos(60) = 1/2 )
Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)
Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)
Hyp = 16[tex]\sqrt{3}[/tex] / 3
x = 16[tex]\sqrt{3}[/tex] / 3
Now use SOH
Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3 ( sin(60) = [tex]\sqrt{3}[/tex]/2 )
(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp
16 * 3 / 6 = Opp
8 = Opp
y = 8
