Answer:
Step-by-step explanation:
<h3>Given GP</h3>
<h3>To find</h3>
<h3>Solution</h3>
<u>Substitute ar in the second equation</u>
- ar⁵= 16
- 4r⁴ = 16
- r⁴ = 4
- r = √2
<u>Then finding a₄</u>
- a₄ = a₂*r² = 4*(√2)² = 4*2= 8
Answer:
81/70
Step-by-step explanation:
5/14+4/5=25/70+56/70=81/70
Answer: 16/25 (sorry I'm not really sure bc I'm just a middle schooler)
Step-by-Step explanation:
2 2/5 km=2.4 kilometers
3 3/4 minutes=3.75 minutes
2.4/3.75=240/375
240/375=48/75=16/25=64/100=0.64
0.64 km/minute (0.64 km per minute)
you can solve the problem using the fractions...
2 2/5=12/5
3 3/4=15/4
(12/5)/(15/4)=(12/5)*(4/15)=48/75=16/25=0.64 again, or you can simplify before multiplying...
(12/5)/(15/4)=(12/5)*(4/15)=(4/5)*(4/5)=16/25...
Answer:
Multiply each side by 6
Step-by-step explanation:
27 = m/6 - 3
Add 3 to each side
27+3 = m/6 - 3+3
30 = m/6
Multiply each side by 6
30*6 = m/6*6
180 = m
Answer:
Sally's km/h during the first half hour is 7 .
<em>The lowest average speed is between the 3rd and 4th stops.</em>
Step-by-step explanation:
On the table during the first half hour, Sally traveled 7 km.
From the first stop to the second stop, she traveled 8 km; from the second stop to the third stop, she traveled 6 km; from the third stop to the fourth stop, she traveled 3 km; from the fourth stop to the fifth stop, she traveled 4 km; and from the fifth stop to the sixth stop she traveled 8 km. Therefore The lowest average speed is between the 3rd and 4th stops.
