Answer:
a =2.2
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2+2^2 = 3^2
a^2 +4 = 9
a^2 = 9-4
a^2 = 5
Taking the square root of each side
sqrt(a^2) = sqrt(5)
a = sqrt(5)
a=2.236067977
To the nearest tenth
a =2.2
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15

Hello,
100a²-49b²=(10a)²-(7b)²=(10a-7b)(10a+7b)
===================================
Answer:
Step-by-step explanation:
14.Since the most common denominator is 40 lets multiply all the denominators to equal all to 40
Evita:24/40
Jack:25/40
Keisha:30/40
Sinjo:20/40
Therefore Keisha drank the most bottles
15. The most common denominator for 5/8 and 2/3 is 24 lets have both denominators equal to 24
5/8 -> 15/24
2/3-> 16/24
Therefore flour is the greater amount
16.Multiply the denominators equal to 6 since thats the least common denominator
1/2->3/6 | 2/3->4/6
Therefore peanuts is the greater ingredient amount
17.If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value. Therefore, equivalent fractions can be created by multiplying (or dividing) the numerator and denominator by the same number.
18.We can compare fractions with unlike denominators by finding the least common denominator and making equivalent fractions. When the denominators are the same, the number with the larger numerator is the larger fraction.
