Answer:
60.28.
Step-by-step explanation:
We need the sine function because we are given the opposite side and we need the hypotenuse.
sin 71 = 57 / x
Cross multiply
x * sin 71 = 57
x = 57 / sin 71
= 60.28.

Answer:
48÷8, -36÷-12
Step-by-step explanation:
hello everyone ,
i am having some problems solving this question in maths
Arrange 13.25 kg, 14560 g, 13.6 kg, 12000 g in descending order ,
Write the following decimals as fractions. Reduce the fractions to lowest
form.
a) 3.6 b) 12.5
i hope u also consider explaining
thank you all .
Answer:
Descending order:
14560g
13.6kg
13.25kg
12000g
a.) [tex]\frac{18}{5}[/tex]
b.) [tex]\frac{25}{2}[/tex]
Step-by-step explanation:
To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.
If we were to put everything into g:
14560g
13600g
13250g
12000g
See how they are still in the correct order?
If we were to put everything into kg:
14.56kg
13.6kg
13.25kg
12kg
Still in descending order!
___________________
Now to find out how to put the decimals into fractions:
Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)
Following this we get:
36
125
Now divide by the same factor (10), we can't change the value of the number, just the way they look!
[tex]\frac{36}{100}[/tex]
[tex]\frac{125}{10}[/tex]
All that's left is it reduce!
[tex]\frac{18}{5}[/tex]
[tex]\frac{25}{2}[/tex]
And as you can see, we are back to the number I had put in the solution!

Answer:
y = -6/5x - 1
Step-by-step explanation:
6x+5y = -5
5y = -6x - 5
y = -6/5x - 1
Answer:
y=-[tex]\frac{6}{5}[/tex]x-1
Step-by-step explanation:
Start by moving x to the other side
5y=-5-6x
Divide by 5 to isolate y
y=-[tex]\frac{6}{5}[/tex]x-1

Step-by-step explanation:
Two fifth of pupils in a standard 7 class were girls.There were 27 boys in the class. ( a) how many girls were there. (b) how many peoples were there in the standard 7 class
Answer:
a. 18
b. 45
Step-by-step explanation:
The question states that 2/5 of the class are girls which means 3/5 are boys:
[tex]\frac{3}{5} = 27[/tex]
Divide this value by 3 to get the value of [tex]\frac{1}{5}[/tex]:
27 ÷ 3 = 9
Multiply this by 5 to find [tex]\frac{5}{5}[/tex], the total pupils in the class:
9 x 5 = 45
As the number of girls is [tex]\frac{2}{5}[/tex] of the total pupils:
9 x 2 = 18
So there are 18 girls in the class which has a total pupil size of 45.
Hope this helps!
Step-by-step explanation:
according to question of ⅖ are girls than ⅗ are boys
so let the number of girls be x
so,
→ ⅗ of x = 27
→ x = 27 × 5/3 = 9×5 = 45
→ x = 45
a ) 45 - 27 = 18
than no. of girls is 18.
b) thier are 45 students in total.
hope this answer helps you dear...take care and may u have a great day ahead!

Answer:
Q4) 256 roses
Q5) 40 hamburgers
Q6) 60 professors and 168 lecturers
Q7) 20 percussionist on the sideline
Step-by-step explanation:
Q4) First to set up a proportion you simply have to write a letter to represent the missing number. In this case we'll be using x. So it'll look something like these:
I) 160:5 = x:8 (using colon) or
II) 160/5 = x/8 (as two equal fractions)
You can use one of the two above.
I used the fractions here to solve the question.
After setting up the proportion, your going to cross multiply to get the value of x so its going to look like this:
160×8 = 5×x
1280 = 5x
5x = 1280
Now you have to divide on both sides to isolate x.
5x÷5 = 1280÷5
x = 256
Therefore your answer is 256 roses.
Q5) Use the same method in Q4.
Q6) This is where the proportion using colon comes in. It should look like this 5:14. 5 representing the professors and 14 the lecturers. Now it said that the total number of faculty members is 228.
First thing your going to do is add the proportion together. So basically 5+14=19.
After acquiring this your going to use the sum to divide the total number of faculty members which is 228. So 228÷19=12.
And finally you now have to multiply both sides of the proportion by 12. Therefore 5×12:14×12
60:168
To make sure the answer is right add the proportions of the working above which will give you the total number of faculty members. 60+168=228.
Your final answer: There are 60 professors and 168 lecturers.
Q7) Use the same method done in Q6.
I gave the answers to questions 5 and 7 because I wanted to give you the opportunity to try out the working outs yourself for a better understanding on your part and see if you can get the same answers as me. Anyway hope this helped.

1. Obtén la pendiente de las siguientes rectas, grafícalas y determina si las rectas L1 y L2, cuyas ecuaciones son 3x+4y-2=0 y 3x+4y+6=0, son paralelas o no.
Queremos obtener la pendiente de dos lineas dadas, y en base a eso, determinar si son paralelas o no.
Las pendientes son para ambas lineas igual a -3/4, como ambas lineas tienen la misma pendiente y diferente ordenada al origen, podemos concluir que son paralelas.
-----------------------------
Una línea en general se escribe como:
y = a*x + b
Donde a es la pendiente y b es la ordenada al origen.
En este problema se nos dan las líneas:
3*x + 4*y - 2 = 0
3*x + 4*y + 6 = 0
Comencemos por reescribir esas líneas en la forma más general, para hacer esto, debemos aislar y en ambas ecuaciones:
y = (-3/4)*x + 2/4
y = (-3/4) - (6/4)
Aqui podemos ver que ambas pendientes son iguales a -3/4
Al final de la respuesta puedes ver el gráfico de ambas líneas.
Como ambas líneas tienen la misma pendiente, pero distintas ordenadas al origen, podemos concluir que son paralelas.
Esto mismo se puede observar en el gráfico de abajo.
