Answer:
6 hours
Step-by-step explanation:
if you take 2 hours and multiply it by 2 you get 4 hours or 2000 and if you take 1000 and divide by 2 you get 500 so add them together and you get 6 hours :)

If a²+b²=8ab, determine (a+b) in terms of a and b
[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]
Answer:
[tex]\mathsf{\sqrt{10ab} }[/tex]
Step-by-step explanation:
We have the rules of indices, one of which is:
[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]
Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.
In the question, we're provided with one equation, i. e.,
a² + b² = 8ab . . . . . . . . (¡)And, were asked to find out the value of (a+b) in terms of ab.
The above rule has variables that fit in the question efficiently!
So, instead of solving for (a+b), we'll be solving for (a+b)², then go for (a + b):
=> (a + b)² = (a² + b²) + 2ab
from eqn. (¡):
=> (a + b)² = 8ab + 2ab
=> (a + b)² = 10ab
taking under root on both the sides:
=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]
That's the answer, [tex]\mathsf{\sqrt{10ab} }[/tex]!

A car begins from rest and accelerates at a rate of +3.0 m/s^2 for 5.0 seconds.
a. Determine the car's final speed.
b. Calculate the car's average speed during its trip
Answer:
15m/s
Step-by-step explanation:
we know that
v = u + at
= 0+ 3*5
=15m/s
The final speed of a car is 15 m/s.
Given that, a car begins from rest and accelerates at a rate of +3.0 m/s^2 for 5.0 seconds.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Here, the initial speed = u = 0
Now using v = u + at formula, we get
v = 0+ 3 × 5
=15 m/s
So, final speed is 15 m/s
Average speed is 15 m/s
Therefore, the final speed of a car is 15 m/s.

Use the Pythagorean theorem to find x, in simplest radical form
Answer:
[tex]4\sqrt{21}[/tex]
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Which in this case:
'c' is hypotenuse. (hypotenuse = 20)
'a' and 'b' are the other sides. (a = x, b = 8)
[tex]a^{2} +b^{2}= c^{2}[/tex] [tex]x^{2} +8^{2} =20^{2}[/tex] [tex]x^{2} + 64 = 400[/tex] [tex]x^{2} = 336[/tex]Now we should just take square root from the both sides.
and the answer will be [tex]\sqrt{336}[/tex] or [tex]-\sqrt{336}[/tex], but a side of a triangle can not be a negative number! so the answer will be [tex]\sqrt{336}[/tex].
As you see [tex]\sqrt{336}[/tex] is not the simplest radical.
We can write [tex]\sqrt{336}[/tex] as [tex]\sqrt{16 * 21}[/tex].
And from the laws of radical we can write [tex]\sqrt{16*21}[/tex] as [tex]\sqrt{16} * \sqrt{21}[/tex].
[tex]\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}[/tex]

What equation could we use to solve for c?
Answer:
first answer i think beacuse it cubic
Step-by-step explanation:
Armand and Jill are 247.5 miles apart, and driving toward each other. Armand is driving at a rate of 50 miles per hour and Jill is driving at a rate of 60 miles per hour.
A table showing Rate in miles per hour, Time in hours, and Distance in miles. The first row shows Armand, and has 50, t and 50 t. The second row shows Jill, and has 60, t, and 60 t
Use the scenario and table to determine which statements are true. Check all that apply.
Armand and Jill will each travel the same distance to meet.
Armand and Jill will travel the same amount of time to meet.
The equation used to find the time, t, it will take for them to meet is 50t + 60t = 247.5.
It will take 4.5 hours for them to meet.
Jill will travel 135 miles to meet Armand.

solve for x
2x-y=r
(Show solving steps please)
Answer:
x=r/2+y/2
Step-by-step explanation:
2x-y=r
you want x all by itself, move y first by adding y
2x = r + y
divide both r and y by 2 to leave x all by itself.
2x/2 = r/2 + y/2
2/2 = 1 so it's really 1x
x= r/2 + y/2

if a hot air balloon owner charges $150 for one hour ride if he gives 6 rides on Saturday and 5 rides on Sunday write and evaluate an expression to describe his total income for the weekend
Answer:
Your expression would be 150(11)=x
The answer to this expression would be 1,650. Producing the equation 150(11)= 1,650
Step-by-step explanation:
Your equation is 150(11)=x because; the hot air balloon owner charges $150 per ride. And there are 11 rides. So our equation is solely saying $150 charged per ride for 11 rides.
Let's solve this equation
150(11)= 1,650
So, we would multiply 150 by 11 to get 1,650.
And if your professor asks a statement for your equation you would say; The total income for the balloon owner that weekend is $1,650. $900 made on Saturday plus $750 made on Sunday.

Line a passes through points (3, 6) and (1, 15). Line b is parallel to line a. What is the slope of line b?
Answer:
9/-2
Step-by-step explanation:
First, find the slope
(15-6)/(1-3)
9/-2
Answer:
[tex]slope\ of \ line\ b = - \frac{9}{2}[/tex]
Step-by-step explanation:
Since line a and b are parallel, the slope of a = slope of b.
therefore,
[tex]slope\ of \ line\ a = \frac{y_2 - y_1}{x_2-x_1} \ \ \ \ \ x_ 1 = 3 , \ y_ 1 = 6 \ , \ x_2 = 1 , \ y_2 = 15[/tex]
[tex]=\frac{15-6}{1-3}\\\\=\frac{9}{-2}\\\\= - \frac{9}{2}[/tex]
[tex]= slope\ of \ line \ b[/tex]

The revenue from selling x shirts is f(x) = 11x. The cost of buying x shirts is cx) = 6 x + 20. The profit from selling x shirts is p(x) = HX) - cx). What is p(x)?
Answer:
P(x) = 5(x) - 4(x) as 20(x) = 4(5) is added to 5(x) = 25 -20 = 5 so profit fro one shirt is set = 1 as 5 * 1 = 5 and (x) = 5
Step-by-step explanation:
11x - 6( ?)+20 = p(?) -H(?) - c (?) = 11x - p(x) = HX) - cx) = 6(x )+20 = 11x-6x -20 = 5x -20 = P(x) = 5(x) - 4(x)
