A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?
Answer:
[-1/2,1/20]
Step-by-step explanation:
Answer:
[-1/2,1/20]
Step-by-step explanation:
In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.
The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.
We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.
The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.
Solve for x in the diagram below.
Answer:
x = 20°
Step-by-step explanation:
here's your solution
=> it is given that whole angle is 90°
=> so, x + (3x + 10) = 90°
=> x + 3x + 10 = 90°
=> 4x + 10 = 90°
=>4x = 90 - 10
=> 4x = 80°
=.
=> x = 80/4
=> x = 20°
one angle is 20° and other 70°
hope it helps
Answer:
20 is your answer
x+3x+10=90 being right angle
4x=90-10
x=80/4=20
Someone help, I don't understand what trig ratio to use, or how to get the answer to w or x
Answer:
Uhm I think you need to like times the 10 to the 56? erm yeaaaaaaa SOrry if you get it wrong
Step-by-step explanation:
Answer:
1:2
Step-by-step explanation:
56*10= 560
34+56= 90
90*10= 900
X is about 2 times the size of W so it would be
1:2 (W:X)

Need help :::::::::::::::::
Answer:
2/3
Step-by-step explanation:
First, we read the two points with circles off the graph.
They are (-4, -5) and (5, 1).
slope = (y2 - y1)/(x2 - x1) = (-5 - 1)/(-4 - 5) = -6/(-9) = 2/3
Answer: 2/3
which number is the closest approximate value for sqrt 105
Answer:
10.
Step-by-step explanation:
Lets define a square root. A square root is a number multiplied by itself. 10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

Step-by-step explanation:
How many roots does y=3x^2+8 have?
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)

find the solution to the system of equations
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]
[tex]\large\text{-4 = 2x + 2}[/tex]
[tex]\large\text{TURN the EQUATION}[/tex]
[tex]\large\text{2x + 2 = -4}[/tex]
[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]
[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]
[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]
[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]

Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.
