Acronym to remember the 3 basic trigonomic functions:

Soh - Cah - Toa

opposite
sin = --------------------
  hypotenuse

adjacent
cos = -------------------
hypotenuse

opposite
tan = -----------------
adjacent

In your case, you can set up a sine trigonomic function, like this:

Sin 48 = 10 (adjacent)
-----
x (hypotenuse)

    10
(x) Sin 48 = ------ (x)
     x

  (x) Sin 48 = 10
-------------- -------------
Sin 48 Sin 48

Plug in 10(sin)(48) into a calculator.

x = 7.43

I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D

Answer:

y = $\frac{3}{8}$ x - 2

Step-by-step explanation:

<u>The answer to this problem is a simple plug-in of the given values into the slope-intercept formula.</u>

Slope intercept formula: y = mx + b

(m = slope)

(b = y intercept)

If the equation has a slope of m = $\frac{3}{8}$ , then the slope-intercept form would be:

y = $\frac{3}{8}$ x

If the y-intercept of an equation is (0 , -2), then the slope intercept form would be:

y = mx - 2

<u>Putting both of these values into an equation would give option A:</u>

y = $\frac{3}{8}$ x - 2

A worker at a snack stand opened a new box of cups. The first day he used 30 cups , the second day the worker used 15 percent of

Sholpan [36]

Answer:

Step-by-step explanation:

the first day he used 30 cups

the second day he used 15% of the remaining cups...a total of 90 cups were used on second day.

so 15%of the remaining cups = 90.....so if u let x be the total cups, then the remaining cups would be x - 30

15% of (x - 30) = 90.....turn ur percent to a decimal..." of " means multiply

0.15(x - 30) = 90

0.15x - 4.5 = 90

0.15x = 90 + 4.5

0.15x = 94.5

x = 94.5 / 0.15

x = 630 total cups <==

lets check..

start with 630 cups....used 30 the first day....leaving u with 600 cups....15% of the remaining cups = 90.....so 15% of 600 = 90....lets check it

15%of 600 = 0.15(600) = 90...yep, thats correct....there were 630 cups in the new un-opened box

What is the mean of 65,30,25

mixas84 [53]

You've got 3 values there.

Get the sum of 65, 30 and 25 and divide their sum by the number of values that exist, which in this case is 3.

$\frac { 65+30+25 }{ 3 } =\frac { 120 }{ 3 } =40$

Answer:

40
