Answer:
The 3rd option is correct.
Step-by-step explanation:
This is because of an exponent rule that goes:
(xy)^z = x^z(y^z)
The whole thing gets raised to the power. Therefore only the 3rd one works (ps. if you can mark as brainliest that would be amazing, but if not that's fine)
It is a.
You multiply 9.3 and 2.5 together and get 23.25
Then just add the exponents 6+3 is 9
So the answer is 23.25 x 10^9

Answer:
The complementary angle is 72
Step-by-step explanation:
Complementary angles add to 90 degrees
Let x be the complementary angle
x+18 = 90
Subtract 18 from each side
x = 90-18
x = 72
x = 26 m is the width of the pool, length: 29+4 = 33 m.
<u>Step-by-step explanation:</u>
We have A rectangular pool is surrounded by a walk 3 meters wide. The pool is 4 meters longer than its width. If the total area of the pool walk is 372 square meters more than the area of the pool.
Let the width of the pool = x
Then the length will = (x+4) ,over all dimensions will be (x+6) by (x+6+4) or (x+10)
Total area - pool area = 372
∴ x = 26 ft is the width of the pool, length: 29+4 = 33 ft
