Which could be the dimensions of a rectangular prism whose surface area is less than 160 square feet? Select two
options.
8 feet by 4 feet by 3 feet
7 feet by 6 feet by 4 feet
03 feet by 7 feet by 8 feet
03 feet by 6 feet by 7 feet
03 feet by 5 feet by 7 feet
Answer:
8 feet by 4 feet by 3 feet
3 feet by 5 feet by 7 feet
Step-by-step explanation:
8 feet by 4 feet by 3 feet
A = 2(wl + hl + hw)
A = 2 · (4 · 8 + 3 · 8 + 3 · 4)
A = 136
3 feet by 5 feet by 7 feet
A = 2(wl + hl + hw)
A = 2 · (5 · 3 + 7 · 3 + 7 · 5)
A = 142

how do movement skills in volleyball transfer to tennis?
Answer:
Tennis – It's not difficult to see that tennis and volleyball have their similarity; both involve hitting a ball over the net in the hope that the opponent won't be able to return it. Much like tennis, volleyball requires short and explosive movements and cat-like reflexes, rather than long runs down a pitch.

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

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

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

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!
Determine the least possible degree of the polynomial function shown
Answer:
yeah
Step-by-step explanation:
To find the degree of the polynomial, add up the exponents of each term and select the highest sum.So the least number of roots = 5 and this will also be the least possible degree of the polynomial

A machine that drills holes for wells drilled to a depth of
-72 feet in one day (24 hours).
At this rate, how many hours will it take until the drill
reaches its final depth of -132 feet?
Answer:
20 hours
Step-by-step explanation:
If the machine drilled 72 feet in 24 hours, we can divide 72 by 24 to find out that the machine drilled 3 feet in one hour.
Next, you must find the distance that must be traveled. You can do this by subtracting 72 from 132. You will get 60
So, if the machine drilled at 3 feet per hour, and it needs to drill 60 feet, it will take 20 hours because 60 divided by 3 is 20.
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.
