Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
Answer:
C
Explanation:
A: 2 in. by 2 in. by 1 in. = 4 cubic inches
B: 1 in. by 1 in. by 1 in. = 1 cubic inches
C: 2 in. by 1.5 in. by 0.5 in. = 1.5 cubic inches
D: 3 in. by 0.5 in. by 1.5 in. = 2.25 cubic inches
Therefore, the answer is C.
Answer: 300a^3cb
Step-by-step explanation:
This question is best answered by finding the least common multiple of both 45 and 20. If a scenario indicates every so many, it would be like listing the multiples. It can be harder to list the multiples of bigger numbers (45, 90, 135, 180 and 20, 40, 60, 80, 100, 120, 140, 160, 180), so another strategy is to use prime factorizations. The prime factorization of 45 is <em>3</em> x <em>3</em> x 5 and the prime factorization of 20 is <em>2</em> x <em>2</em> x 5. The numbers that are the same in both prime factorizations are part of your answer. All other numbers (the italicized ones) also become a factor in your final answer, so 5 x 3 x 3 x 2 x 2 = 180. This means 180 minutes later they both start again at the same time. So 3 hours from 9 am is 12 noon.
Answer:
1.4×10⁵
Step-by-step explanation:
first simplify the power of 10 then get 7÷5 = 1.4
1.4×10⁵ is the answer
