Ratios and fractions are interchangeable (for the most part). A fraction is a type of ratio. And we've all worked with fractions before, so that's what we'll do here.
I can say that the ratio 3:1 is the same as the fraction 3 / 1. Using that fraction, it is fairly easy to find equivalent fractions.
3 / 1 = 6 / 2 = 9 / 3 = 30 / 10
...And so on
Another example, 5:6 = 5 / 6.
5 / 6 = 10 / 12 = 15 / 18 = 30 / 36
To find equivalent fractions, all you need to do is multiply both the numerator and denominator by the same number. As long as that number is the same (and your multiplication is correct), then the new fraction will be equivalent to the original.
Hope this helps!
Answer:
4.891
its side b (opposite side of the 50 degree angle)
Step-by-step explanation:
side c = 6
angle A is 20 side a (opposite side) = 2.184
angle B is 50 side b (opposite side) = 4.891
angle C is 110 side c (opposite side) = 6
1.
get third angle
50 + 20 = 70
180 - 70 = 110
third angle C is 110
2.
get side a
sin A/a = sin C/c
a/c = sinA/sinC
a = c * sinA/sinC
a = 6 * (sin20/sin110)
get sin in degrees
a = 6 * (.342/.9397)
a = 2.184
First find her salary this year by dividing the amount she saved by the percentage saved:
$4,620 / 0.11 = $42,000
Her salary now is $1000 more than the previous year, so now subtract $1000 from her present salary:
42,000 - 1,000 = $41,000
Answer: The answer is x = 65 - 60y.
Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.
Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).
Also, given is the following information -
Raul's age = Grandfather's age - 60 × sister's age.
Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age
Thus, we can find Paula's age (y) using the equation
where 'x' is the age of Raul.
Answer:
x=-6
Step-by-step explanation:
use distributive property on the () and times x and 1 by three
then you subtract 6 from both sides
then subtract three from both sides
then divide both sides by 3
your work would look like this:
3(x+1)+6=-9
3x+3+6=-9
3x+3=-15
3x=-18
x=-6
Hope this helps!
