Let's add 1/4 and 1/3.Before we can add these fractions, we'll need to change them so they have the same denominator.To do that, we'll have to find the LCD, or lowest common denominator, of 4 and 3.

I got this from the internet u should ask google first befor puting it into brainliy

How do you subtract 4/5 - 3/10?

Very tricky... If you don't know how to do it!

First make them equivalent. 4/5 = 8/10.

8/10 - 3/10 = 5/10

If you want to simplify, it would be 1/2 because we need a number that (in this case) 5 and 10 both go into. They both go into 5 and so divide 5 by 5, and 10 by 5.

You will get 1/2.

PLEASE HELP WITH GEOMETRY WILL GIVE BRAINLIEST

sammy [17]

Answer:

Option D

Step-by-step explanation:

In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles

The Rule says

$\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}$

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.

Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.

Example

in first option we can apply Sine Rule as

$\frac{\sin 84}{x}=\frac{\sin 63}{3}$

$\frac{0.994}{x}=\frac{0.891}{3}$

$x=\frac{0.991 \times 3}{0.891}$

$x=\frac{2.973}{0.891}$

$x=3.336$

there are 360 students in a school 162 of them are girls find the percent of girls find the percent of boys

Ronch [10]

Answer:

Total number of students = 360

Total number of girls = 120

Total number of boys = x / ?

120/240= 1/2

50%

Step-by-step explanation: To find out the percent of the boys you first

subtract the whole amount of students which is 360 students in total to the number of girls (120) resulting 240. 240 in ratio is 1/2. 1/2 is 50%.

(Not sure, if this helps or not. I try my best to answer questions to make the asker to understand! Sorry, I tried. :c)

Write y=10x as a logarithmic function please

Margaret [11]

$\bf \textit{exponential form of a logarithm}
\\\\
log_a b=y \implies a^y= b\qquad\qquad 
% exponential notation 2nd form
a^y= b\implies log_a b=y \\\\
-------------------------------\\\\
y=10^x\implies log_{10}(y)=x$
