Answer:
? = 4.29
Step-by-step explanation:
Remark
Let x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.
Equation
14/(14+ 4) = 15/(x + 15) Combine like terms on the left
14/18 = 15/(x + 15) Cross multiply
14*(x + 15) = 18 * 15 Simplify the right
14(x + 15) = 270 Divide by 14
x + 15 = 270 / 14
x + 15 = 19.29 Subtract 15 from both sides
x = 19.29 - 15
x = 4.29
-- 100% of the original number is ALL of it.
-- If it's increased by that amount, it becomes DOUBLE
(twice as much as) what it was originally.
2_10 i'm guessing means 2/10, so in percentage, it would be 20%
Answer: i) 216 liters ii) 60 cm
<u>Step-by-step explanation:</u>
i) 216,000 cm³ × 1 liter/1000 cm³ = 216 liters
ii) ![\sqrt[3]{216,000\ cm^3} =60\ cm](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%2C000%5C%20cm%5E3%7D%20%3D60%5C%20cm)
