Is 10 the solution of the equation 4x - 8 = 31?
Which expression is NOT equivalent to −6×(13+13)? −63+13 −6×23 −6×(2×13) (13+13)×(−6)
Answer:
I know that -63+13= -50
(-6) * 23 = (-138) are NOT equivalent, the only expressions that are equivalent are (13+13)x(-6) and -6x(2x13) they both equal to -156 which is to say -6x(13+13) Are the same

Find value of x
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

If there are 150 people born in the world every minute; how
many are born every Hour? Day? Year?
Step-by-step explanation:
150 x 60 = 9,000 every hour
9000 x 24 = 216,000 every day
216000x 365 = 78,840,000 every year
Answer:
Hour: 9,000 people
Day: 216,000 people
Year: 78,840,000 people
Step-by-step explanation:
In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:
Hour: 60 minutes
Day: 60 minutes × 24 hours = 1,440 minutes
Year: 60 minutes × 24 hours × 365 days = 525,600 minutes
Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:
Hour: 60 minutes × 150 people = 9,000 people
Day: 1,440 minutes × 150 people = 216,000 people
Year: 525,600 minutes × 150 people = 78,840,000 people

Tyler is designing a banner that will welcome people to a festival. The design for the banner has an
area of 1.5 square feet. The actual banner will be a dilation of the design by a factor of 5. What will
the area of the actual banner be?
Answer:
7.5 sq ft
Step-by-step explanation:
1.5*5=7.5
The design is 1/5 of the actual size, so you just multiply by 5 to get the real size.

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.

The graph of a twice differential function is shown at right. Which of the following is true?
Answer:
(C)
Step-by-step explanation:
looking from the slope: f'(2) is negative
f(2)=0
the curve concave upward: f''(2) is positive
f'(2)<0
f(2)=0
0<f''(2)
f'(2)<0<f''(2)
The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.
What is a differential function?A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
Given:
The coordinate of the graph is shown in figure (2, 0),
As we can see from the graph, the slope: f' (2) is negative (Downwards)
Again, from the graph
f(2) = 0
Thus, the curve concave upward: f'' (2) is positive (upward)
f' (2)<0
f (2)=0
0 < f'' (2)
f' (2) < 0 < f'' (2)
Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

Jamal has 30 ounces of a 20% saline solution. This means 20% of the solution is salt. He combines this solution with 25 ounces of a 30% saline solution.
What is the total amount, in ounces, of salt in the combined mixture? Please help and please provide an explanation?
Answer:
12.5 or 12 1/2 (may be wrong)
Step-by-step explanation:
First I set up a formula to solve how many ounces of salt there were out of 30,
x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.
