It took a skydive 6 seconds to drop 720feet. What is the rate (in feet per/second) of the skydive's drop?
Answer:
120ft/sec
Step-by-step explanation:
Assuming that there is no acceleration, divide the amount of feet (720) with the time (6 seconds):
720 ft/6 sec = 120 ft/1 sec
For every second, the skydiver drops 120 ft.
120ft/sec.

W/5=3 what does w equal
Answer:
w=15
Step-by-step explanation:
w/5=3
multiply by 5 on both sides
w=3*5
∴ w=15
Answer:
15
Step-by-step explanation:
If something over 5 is 3, that means w divided by 5 equals 3.
That can bve translated to W=3 times 5, which is 15.
Therefore, W= 15.

divide 5kg in the ratio 13:7
Answer:
1.75 kg
Step-by-step explanation:
13/20 of 5 = 13/20 x 5= 3.25 kg
and, 7/20 of 5 = 7/20 x 5=1.75 kg
so, divide, 5 kg in ration of 13:7 is:
3.25 kg : 1.75 kg
Answer:
3.25 Kg : 1.75 Kg
Step-by-step explanation:
Sum the parts of the ratio, 13 + 7 = 20 parts
Divide the amount by 20 to find the value of one part of the ratio.
5 Kg ÷ 20 = 0.25 Kg ← value of 1 part of the ratio, thus
13 parts = 13 × 0.25 =3.25 Kg
7 parts = 7 × 0.25 = 1.75 Kg

Let the function f be continuous and differentiable for all x. Suppose you are given that f(−1)=−3, and that f'(x) for all values of x. Use the Mean Value Theorem to determine the largest possible value of f(5).
Answer:
Step-by-step explanation:
By MVT,
[tex]f'(c) = \frac{f(5)-f(-1)}{5-1}[/tex]
[tex]4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3[/tex]
Moreover, [tex]f'(x)\leq 4~~~~~~ \forall x,[/tex]
[tex]f(5) \leq 16 - 3 =13[/tex]
Hence the largest possible value of f(5) is 13

What is the sum of -2-(-17)
Answer: Hi!
Remember, when you're subtracting a negative, that's equal to adding a positive. So -2-(-17) is actually equal to -2 + 17!
-2 + 17 = 15
The expression -2-(-17) is equal to 15.

What is the value of the expression when y = 2? StartFraction 2 minus y Over 4 plus y EndFraction plus StartFraction 3 (y plus 2) Over y EndFraction 3One-half 6 6One-sixth 12
Answer:
6Step-by-step explanation:
Given the expression [tex]\frac{2-y}{4+y} + \frac{3(y+2)}{y}[/tex], we are to look for the value of the expression when y = 2. To do that we are going to substitute y as 2 into the given expression and simplify the resulting expression as shown.
[tex]f(y) = \frac{2-y}{4+y} + \frac{3(y+2)}{y}\\\\if \ y = 2;\\\\f(2) = \frac{2-2}{4+2} + \frac{3(2+2)}{2}\\\\f(2) = \frac{0}{6} + \frac{3(4)}{2}\\\\\\f(2) =0 + \frac{12}{2}\\\\\\f(2) = 6[/tex]
Hence the value of the expression when y = 2 is 6
Answer:
The answer is 6
How you get this answer is by plugging in the number 2 in as y and following the order of operations.
Emily was digging for gold. She dug a total of 40 feet deep into the ground. She dug 17% every minute. How far had she dug after 3 minutes?
Answer:
91 feet or 51
Step-by-step explanation:
17x 3= 51
51 + 40(what she dug before)
or it's just 51
Answer:
60.4 ft deep
Step-by-step explanation:
17% = .17
40 * .17 = 6.8 per hour
6.8 * 3 = 20.4
20.4 + 40 = 60.4 ft deep

The solution of the given quadratic equation is x = -1 ±√2
What is a solution for a quadratic equation?Suppose that we've a function y = f(x) such that f(x) is quadratic.
When y = 0, then the values of x for which f(x) = 0 is called the solution of quadratic equation f(x) = 0. This solution gives values of x, also when we plot x and f(x), we will see that the graph intersects the x-axis at its solution points.
The quadratic formula is given as;
x² + 2x =1
Then its solutions are given as;
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \dfrac{-2 \pm \sqrt{2^2 - 4(-1)}}{2}\\\\x = \dfrac{-2 \pm \sqrt{4 + 4}}{2}\\\\\\x = \dfrac{-2 \pm \sqrt{8}}{2}\\\\x = \dfrac{-2 \pm 2\sqrt{2}}{2}\\\\\\x = \dfrac{-1 \pm 1\sqrt{2}}{1}[/tex]
Therefore, the solution is x = -1 ±√2

Answer:
Take the information given and create an equation that add up to 360.
Step-by-step explanation:
You might assume the smallest angle to be the given 55, so that would make the third term 120+55. The fourth angle is unknown, x
The equation sets up as
55+65+(55+120)+x = 360
Add all the numbers to get 295.
295+x=360
Subtract 360-295 = x
x=65
The four angles are 55°,65°,175° and 65°

If a truck travels at a constant speed and travels 238 miles in 3.5 hours then at what speed did the truck travel
Answer: Hi! Here we're trying to find the unit rate.
So we know that the truck travels 238 miles in 3.5 hours. To find the unit rate, the speed of miles per hour, all we need to do is divide the miles by the total time!
238 ÷ 3.5 = 68
So, the truck travels at 68mph.

Answer:
[tex]\huge\boxed{Option \ B}[/tex]
Step-by-step explanation:
1) 3 + 2 = 5 [Since the result is a natural number, it is a rational number]
2) [tex]\sqrt{19} + \frac{7}{2}[/tex] [ It has a square root that cannot be simplified further so the sum of this is an irrational one ]
3) [tex]\frac{18}{3} + \frac{11}{10000}[/tex] [The sum of it is rational i.e. in the form of p/q ]
4) -6+ (-3.251) = -6-3.251 = -9.251 [ Since the result is an integer, it is a rational number]
Answer:
[tex]\Huge \boxed{\sqrt{19} +7}[/tex]
Step-by-step explanation:
Rational numbers can be integers, fractions, and whole numbers.
Rational numbers can be expressed as fractions p/q, where p and q are whole numbers.
[tex]3+2=5[/tex]
5 is whole number, it is a rational number.
[tex]\sqrt{19} +7= 11.358899....[/tex]
[tex]\sqrt{19}[/tex] is an irrational number, it cannot be expressed as a fraction p/q, where p and q are whole numbers.
[tex]\displaystyle \frac{18}{3} +\frac{11}{10000} =\frac{60011}{10000}[/tex]
The result is rational, it can be expressed as a fraction p/q, where p and q are whole numbers.

The result is rational, it can be expressed as a fraction p/q, where p and q are whole numbers.
Rectangle ABCD is shown. A is at negative 5, 1. B is at negative 5, 3. C is at negative 1, 3. D is at negative 1, 1. Rectangle ABCD is rotated 180°. What rule shows the input and output of the rotation, and what is the new coordinate of A′? (x, y) → (−x, −y); A′ is at (5, −1) (x, y) → (−y, x); A′ is at (−1, −5) (x, y) → (y, −x); A′ is at (1, 5) (x, y) → (x, −y); A′ is at (−5, −1)
Answer:
(x, y) ⟶ (−x, −y); A′ is at (5, −1)
Step-by-step explanation:
When you rotate a point 180° about the origin, it travels along the circumference of a circle and ends up in a diagonally opposite location.
The x and y values of its coordinates become the negatives of the original values.
The rule is
(x,y) ⟶ (-x,-y)
If the coordinates of A are (-5,1),
The coordinates of A' are (5,-1).

Find the value of $B - A$ if the graph of $Ax + By = 3$ passes through the point $(-7,2),$ and is parallel to the graph of $x + 3y = -5.$
Answer:
-6
Step-by-step explanation:
The parallel line can be written using the same x- and y-coefficients, but with a different constant:
x +3y = constant
For the line to go through the given point, the constant must be ...
(-7) +3(2) = constant
-1 = constant
In order for the constant to be +3 instead of -1, the entire equation must be multiplied by -3:
-3x -9y = 3 ⇒ A = -3, B = -9
Then the expression B-A is ...
B -A = (-9) -(-3) = -6
The value of B - A is -6.
