1.6cm² · 20,000² = 1.6cm² · 200,000,000 = 320,000,000cm²
1m = 100cm therfore 1m² = 100² cm² = 10,000cm² therefore 1cm² = 0.0001m²
320,000,000cm² = 320,000,000 · 0.0001m² = 32,000m²
Answer: 32,000m²
Answer:
1 / 3 and 8 / 11
Step-by-step explanation:
When you find the reciprocal of something you flip the number over e.g
Find the reciprocal of 1 /2,
You ' flip it ' and it becomes 2 / 1 or 2
The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.
A=1/2(9)(4)
Multiply to get 18 square cm, which is choice D.
Answer:
C −2a^3+9a^2+45a+6ab^2+18b^2
Step-by-step explanation:
(a+3) ( −2a^2+15a+6b^2)
Distribute the a to the large term in parentheses and the 3 to the large term in parentheses
a ( −2a^2+15a+6b^2)+3 ( −2a^2+15a+6b^2)
−2a^3+15a^2+6ab^2 −6a^2+45a+18b^2
Combine like terms
−2a^3+15a^2−6a^2+6ab^2 +45a+18b^2
-2 a^3 + 9 a^2 + 6 a b^2 + 45 a + 18 b^2
Answer:
y=5x+9 because it has the same slope as the original line.
