PEMDAS means we do exponents before we multiply.
10 ^ 7 = 10,000,000
(10 * 10 * 10 * 10 * 10 * 10 * 10)
5.8 * 10,000,000
= 58,000,000
Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=
base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
This is Pythagorean theorem, a^2+b^2=c^2 , a = 33 and c = 37 so b^2 + 1089 = 1369 , b^2 = 280 , b = 16.73m
Answer:
1 mile = 15 seconds
Step-by-step explanation:
3 minutes and 15 seconds = 3 min + 15 sec
1 minute = 60 seconds
15 seconds =15/60 = 0,25 min
then
3minutes and 15 seconds = 3.25 minutes
13miles in 3 minutes and 15 seconds
= 13 miles / 3.25 minutes
= 4 miles / 1 minute
every minute Jose ran 4 miles
then:
4 miles is a 1 minute
1 mile is a T minutes
T = 1*1/4
T = 1/4 minute
1 minute = 60 secomds
1/4 minute = 60*1/4 = 60/4 = 15 seconds
