Answer:
349800
4
Step-by-step explanation:
First Part:
The question tells you to multiply by 10 to the power of 4.
This implies that you can move the decimal point 4 numbers to the right
When you move the decimal two numbers to the right you get 3498
Then you got to move it two more numbers to the right
3498 can also be written as 3498.0000000000 (infinite amount of zeros)
So moving the decimal two more places you get 349800
Second Part:
10^4 = 10 * 10 * 10 * 10
= 10000
Count the zeros you get 4.
Step-by-step explanation:
5.14×10^6 + 7.2×10^5
51.4×10^5 + 7.2×10^5
58.6 ×10⁵
=5.86× 10⁶

Answer:
40 min is the answer
Step-by-step explanation:
To solve this we need to convert all the units into SI units
for ritu,
speed= 90km/hr
= 90 × 1km/ 1hour
= 90×1000/3600 m/s
= 25m/s
distance = 120×1000m
time = distance/ speed
= 120000/25
= 4800sec
= 4800/60min
= 80 min
for garima,
distance =120×1000m
speed = 60km/hr
= 60×1000/3600 m/s
=100/6 m/
time = 120000/(100÷6)
= 7200sec
= 7200÷60 min
= 120 min
time difference is 120-80 = 40 min
Answer:
Actual height of church = 512 feet
Step-by-step explanation:
Given:
Scale model;
1 inch = 256 feet
Height of church (Scale model) = 2 inches
Find:
Actual height of church
Computation:
Actual height of church = Height of church (Scale model) x scale length
Actual height of church = 2 inches x 256 feet/inches
Actual height of church = 2 x 256 feet
Actual height of church = 512 feet
