Hey there! :)

She had $120 and spent 53% of it

Find 53% of 120

53% = 0.53

0.53 × 120 = 63.6 = $63.60

The game costs $63.60

Hope this helps :)

Whatever% of anything is just (whatever/100) * anything.

She spent 53% of the 120 bucks, what is 53% of 120? well, is just (53/100) * 120.

Given the sequence 12, 9, 6, 3,........ where x = 0, 1, 2......,

Nitella [24]

Answer:

f(x) = -3x + 12

Step-by-step explanation:

The chart could be represented like this:

x y

0 12

1 9

2 6

3 3

Suppose that f(x) = y

And substitute x values.

y = -3x + 12

"x = 0"

y = -3(0) + 12

y = 0 + 12

y = 12

"x = 3"

y = -3(3) + 12

y = -9 + 12

y = 3

From the results, it corresponds to the function.

What is the formula and slope of (18, -7) and (18, 2)

Luden [163]

Answer:

Step-by-step explanation:

Coordinate points: (18, -7) and (18,2)

m= rise / run or $\frac{ y_2 - y_1} {x_2 - x_1}$

m = slope

(x1, y1) = coordinates of first point in the line

(x2, y2) = coordinates of second point in the line

So your rise is...

2 - (-7)

and you run is...

18 -18

Rise = 9

Run = 0

Now, do you see the issue...

You can not have a number over 0 (* a great way to remember is N/0 spells no: "N" being number and "0" being zero)

The slope or the equation 9 / 0 (9 divided by 0 or 9 over 0) is ERROR in the calculator which means the slope of these points are undefined

The line is vertical when this happens

*Side Note: if you were to have 0 as you rise and 9 as your run, 0/9 is ok because that means you have a zero slope meaning that you have a horizontal line

0 divide by 9 is zero

Suppose that E and F are two events and that P(E)=.8 and P(F/E)=.6 What is P(E and F)?

jeka57 [31]

Lets turn E into x and F into y.

We already know that x is 0.8. And if y/x = 0.6, we have to figure that out.

y/x = 0.6

y/0.8 = 0.6

Multiply by 8 to get y = 0.48.

So we have to find P(xy)

So if we know that x = 0.8 and y = 0.48 then all we have to do is multiply 0.48 and 0.8.

0.48 * 0.8 = 0.384

P(E and F) is 0.384.

A flight from Boston to London took only 5 hours because of a strong tailwind. The flight back to Boston against the same wind t

Nata [24]

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph
