FYI this is probably the easiest question I have ever seen. Just use a calculator. The answer is 9R1
Answer:
Hello! answer: 268 square meters
Step-by-step explanation:
To find the total surface area you find the area of each face then add them up so...
10 × 3 = 30
10 × 3 = 30
8 × 3 = 24
8 × 3 = 24
10 × 8 = 80
10 × 8 = 80
Now that I found the area for each face I will just add them up so...
30 + 30 + 24 + 24 + 80 + 80 = 268 therefore the area is 268 square meters Hope that helps!
Answer:
7 minutes 48 seconds.
Step-by-step explanation:
Average speed for the whole journey is
distance / time, so
105 = (2*80)/ (t + t2)
where t is the time when it is moving and t2 is the time it stays at town Q.
Time for journey P to Q
= distance / speed
= 80 /120
= 2/3 hours,
Time for journey Q to P
= 80/110
= 8/11 hours
So t = 2/3 + 8/11
= 46/33 hours.
- and substituting in the equation for the whole journey:
160 / (46/33 + t2) = 105
105*46/33 + 105*t2 = 160
105 t2 = 160 - (105*46)/33
= 160 - 146.364
= 13.636
t2 = 13.636/105 = 0.1299 hours.
= 7 minutes 48 seconds.
Answer:
Binomial
Step-by-step explanation:
P = a² + bcd³
The polynomial contains two terms, so it is a binomial.
