Using trigonometry (tan equation)

the tan equation is as follows: tan(angle) = opposite/adjacent

adjacent side = 7.7 (adjacent has two angles which lie on the side)
opposite side = x
tan angle = 59

Solving for the opposite side x = tan(59) multiplied by 7.7

x = 12.81 (2 decimal places.)

john read the first 114 pages of a novel which is 3 pages less than 1/3 of the novel. write the equation

tatyana61 [14]

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

Step-by-step explanation:

The equation has to be formed by using the given information.

Let p be the total number of pages in the novel

Then

1/3rd of the p will pe:

$\frac{p}{3}$

Total pages read by John = 114

Then according to the statement

$114=\frac{p}{3}-3$

We can solve the equation to get the total pages of the novel

$114=\frac{p}{3}-3\\Adding\ 3\ on\ both\ sides\\114+3=\frac{p}{3}-3+3\\117=\frac{p}{3}\\Multiplying\ both\ sides\ by\ 3\\3*117 = \frac{p}{3}*3\\p=351$

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

Solve for the indicated variable

GrogVix [38]

Answer:

$X_1=\frac{YX_2}{X_2-Y} \\\\$

Step-by-step explanation:

$\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}$

First subtract the 1/x2

$\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}$

Next subtract the fractions on the left

$\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\$

Next Multiply by x1

$\frac{(X_1)X_2-Y}{YX_2}=1\\$

Next divide both sides by the remaining parts (not x1)

$X_1=\frac{YX_2}{X_2-Y} \\\\$

I WILL GIVE BRAINLIEST TO BEST EXPLANATION!! How many 6-digit numbers, formed using each digit from 1 to 6 exactly once, are div

wolverine [178]

Answer:

There are 360 such numbers.

Step-by-step explanation:

The number of 6-digit numbers, formed using each digit from 1 to 6 excactly once, means we can have numbers like

123456, 123465, 123546,123564,.... 654321

The number of such numbers is given by 6! because we have a choice of 6 numbers for the first digit, 5 left for the next, ... until the last digit has only one choice.

6! = 6*5*4*3*2*1 = 720

We know that 1+2+3+4+5+6 = 21 is divisible by three, so all 720 numbers are divisible by 3.

However, to be divisible by six, we need a number divisible by three AND divisible by two.

Thus, out of the 720 numbers, we need count only the even numbers, which are exact half of the 720, or 360.

Therefore there are 360 6-digit numbers, formed using each digit from 1 to 6 exactly once, are divisible by 6.
