Answer:
2.1 * 10 ^3
Step-by-step explanation:
5.67 * 10 ^7 ÷2.7 x 10^4
Divide the numbers
5.67 / 2.7 =2.1
Divide the exponents
10^7 / 10 ^4
Remember when dividing power, we subtract the exponents
10 ^(7-4) = 10^3
Put this back together
2.1 * 10 ^3
Verify that this is in scientific notation
Since this is in scientific notation, we are done
Answer:
No
Step-by-step explanation:
25% as a decimal is 0.25
and 0.3 as a percentage is 30%
Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27

Answer:
The speed of the object at time, t=4 is 
Step-by-step explanation:
The speed is calculated using the formula;
The distance covered by the object is given in terms of t, as
At time t=4, the distance covered by the object is;
The speed can now be calculated by substituting t=4 and distance 80 meters to obtain;
