Answer:
1
Step-by-step explanation:
There is an important trig identity which you must know: (sin x)^2 + (cos x)^2 = 1.
Therefore, sin^2(20°)+cos^2(20°) = 1
Answer:
your answer will be x = 5
Step-by-step explanation:
Answer: 625
Step-by-step explanation:
Here are the steps to convert .3125 into fraction form:
First we write .3125 as
.3125
1
Now we multiply both the numerator and denominator by 10 for each digit after the decimal point:
.3125
1
=
.3125 x 10000
1 x 10000
=
3125
10000
In order to reduce the fraction we find the Greatest Common Factor (GCF) for 3125 and 10000. Keep in mind a factor is just a number that divides into another number without any remainder.
The factors of 3125 are: 1 5 25 125 625 3125
The factors of 10000 are: 1 2 4 5 8 10 16 20 25 40 50 80 100 125 200 250 400 500 625 1000 1250 2000 2500 5000 10000
The Greatest Common Factor (GCF) for both 3125 and 10000 is: 625
Answer:
<h2>Sophia is not correct</h2>
Step-by-step explanation:
This is a ratio problem and Sophia is expected to simplify the ratio by finding the smallest possible values and not to compound it by multiplying by some values
We can represent the given ratio 60:36 as a fraction.
60/36
we proceed to reduce the fraction by dividing both the numerator and the denominator by a common factor say 6
10/6
We can further reduce with a common factor of 2
5/2
re-writing the ratio we have 5:2
