y = v₀t - gt²/2
For y=0 (back to where we started),
0 = t(v₀ - gt/2)
t=0 (which we knew) or v₀ - gt/2 = 0
v₀ = gt/2
2v₀ = gt
t = 2v₀/g
t = 2 (35.7 m/s) / (9.8 m/s/s) = 7.3 seconds
Answer: 7.3 seconds

Helppp
Answer:
1
Step-by-step explanation:
-3a+4 =7
-4. _4
-3a=3
divide by -3 on both sides
a=-1
3+4=7
Answer:
a= [tex]-3\frac{2}{3}[/tex] or ≈ -3.66
Step-by-step explanation:
-(3a+4)=7
-3a-4=7
Add 4 to both sides
-3a=11
Multiply both sides by -1
3a= -11
Divide both sides by 3
a= [tex]-3\frac{2}{3}[/tex]

Answer:
The correct sign is : <
Step-by-step explanation:
3.126 *10^2 is greater than 31260000*10^-9 by 312.56874
Answer: <
Step-by-step explanation:
10^-9 = .00000001
Multiply
31,260,000 * .00000001 = .3126 * 10^0 (1)
10^2 = 100
Multiply
3.126 * 100 = 312.6
.3126 * 10^0 < 3.126 * 10^2

I didn't do the last ordered pair because we already found one that fit the equation. Also, it wouldn't be a 1:1 equation if that last one was true, so you can rule it out once you see that (-3,-2) is the correct answer.

The maximum amount Ban can afford for a' mortgage each month when he makes $39,600 a year is $825. Option B is correct.
What is mortgage?The mortgage is a type of loan which is taken to purchase the home or lands.
In the given problem, Ben makes $39,600 a year. The rate of interset for the mortgage he has is 4. Thus, the amount he can afford for a'mortgage each year is,
[tex]M=\dfrac{39600}{4}\\M=9900[/tex]
There is total 12 months in one year. Thus, the maximum amount he can afford for a'mortgage each month is,
[tex]M=\dfrac{9900}{12}\\M=825[/tex]
Thus, the maximum amount Ban can afford for a' mortgage each month when he makes $39,600 a year is $825. Option B is correct.

Give an example of an absolute value inequality whose answers falls between two values. Give an example of an absolute value inequality whose answers fall outside of two values. What creates the difference? Be specific. *
Answer:
A) Suppose we have an onedimensional situation.
in the 0 of our x-axis, we have a fruit tree, and we want to rest at a distance no bigger than 6 ft of the tree, then all the possible positions of our resting place are:
x ∈(-6ft, 6ft)
we can write this as: IxI < 6ft
b) now we think the opposite situation, we want to rest at least 6ft away from the tree, then we have that:
x ∉ [-6ft, 6ft].
or IxI > 6ft.
So you can see that the difference in those two cases is if we want to be "inside a given range" (for the first case) or "outside a given range" (for the second case).

Question 3. Option B,

Question 5. Option B
Step-by-step explanation:
Question 3.
If we have a table, we can note that each juice has a proportionality among one another - comparative to the number of servings. If we can figure out this proportionality, we can apply it to the servings of grapefruit juice;
[tex]8 / 16 = 1 / 2,\\4 c / 8c = 1 / 2,\\1 c / 2 c = 1 / 2[/tex]
As we can tell, this " proportion " is 1 to 2. Thus, the amount of grapefruit for 16 servings is 2 * 3 = 6c - Option B
Question 4.
The distance Carlos biked is 24 miles, the total distance he covered is 30 miles;

Question 5.
If 1 / 6 of the fruits are oranges, there must be 6 times of the other fruit. Thus, the solution is Option B
Answer:
Question 3: 6c
Question 4: 4 to 5, 4:5, 4/5
Carlos biked 24 miles and ran 6 miles. The total distance is equal to 30 miles.
The question is: How much of the total distance he biked?
[tex]$\frac{24}{30}=\frac{4}{5} $[/tex]
Question 5: 3 oranges and 15 apples
[tex]$\frac{1}{6} $[/tex] of the fruits are oranges.
It means that approximately [tex]16.6\%[/tex] of the fruits are oranges. If there were 6 fruits, 1 is orange and 5 are apples, therefore B is wrong.
If you take the options, only the first one is correct.
A cylindrical tin of height 15 cm and radius 4 cm is filled with sand from a rectangular box. How many times can the tin be filled if the dimensions of the box are 50 cm by 40 cm by 20 cm?
Answer:
Volume of Box / volume of tin = number of tins required
Volume of box =50*40*20= 40000 cu.cm
Volume of Tin = pi*r^2*h=pi*4^2*15 = 754 cu.cm
4000/754= 53 tins (rounded off)

Mrs. Holland purchased a computer. She initially put down $105.40 and will pay $20.60 per
month until the computer is paid off. Use the equation b = 105.40 + 20.60m to determine
how many months it will take to pay off the computer if the total cost was $682.20
Answer:
It will take her 28 months
Step-by-step explanation:
You first subtract 682.20 and 150.40 to get 576.80. Then you divide 576.80 by 20.60 to get 28.
Answer:
The Answer you are looking for is 28 months.
A bicycle tire is 28 inches in diameter. Approximately how far does the bicycle move forward
each time the wheel goes around? (Use as an approximation for 7r.)?
Answer: 88 inches
Step-by-step explanation:
So the radius of the tire is computed by dividing it in half. We know that in one round of the wheel, the wheel moves to a distance equal to the circumference of the wheel. So each time the wheel goes around, the bicycle moves about 88 inches 88 i n c h e s forward.

Use Pythagorean’s Theorem
Answer:
x =3.9
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 =c^2
x^2 + (5x)^2 = 20 ^2
x^2 + 25x^2 = 400
Combine like terms
26 x^2 = 400
Divide each side by 26
x^2 = 400/26
Take the square root of each side
sqrt(x^2) = sqrt(400/26)
x = sqrt(400/26)
x =3.922322703
Rounding to the nearest tenth
x =3.9
Answer:
3.9
