Answer:
a=15
Step-by-step explanation:
By pythagoras' theorem
25²=20²+a²
625=400+a² group like terms
a²=625-400
a²=225

therefore a=15
Answer:
198
Step-by-step explanation:
Because 6 to the power of three is 6 x 6 x 6 = 216 - 18 = 198
4 / 0.80 = 12 / x...cross multiply
4x = 0.80 * 12
4x = 9.6
x = 9.6 / 4
x = 2.4.....12 apples cost $ 2.40
Answer:
40 miles per hour
Step-by-step explanation:
change hours and minutes to hours
12 minutes = 12 minutes * 1 hr/ 60 minutes = 12/60 hrs
12/60 = 1/5 = .2 hours
1 hours 12 minutes = 1.2 hours
48 miles in 1.2 hours
48/1.2 = 40 miles/hour
