Answer:
b=20 yards
Step-by-step explanation:
15^2+x^2=25^2
225+x^2=625
x^2=400
x=20
Since irrational numbers are forever going, multiplying any nonzero rational number with an irrational number will make the product irrational as well
Given:
8 2/3 hours per month
12 months in a year.
Number of hours she play soccer in a year.
8 2/3 must be converted to improper fraction.
((8*3)+2)/3 = 26/3
26/3 * 12 = (26 * 12)/3 = 312/3 = 104
Yolanda spends 104 hours in a year playing soccer.
Jony is 2 now and is 2x older than Chika. So Chika is 1 year old. This means Chika is 1 year younger than Jony. When Jony is 30, Chika is 29
X^2+20x+10 that's the answer
