Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.
It says that three-fourth of the total weight is metal and says to find the weight of wooden part.
We can find the weight of metal part and then subtract it from the total weight to calculate the answer.
Total weight = 14.9 kilograms.
Metal part = three-fourth of total weight = 
Wooden part = 14.9 - 11.175 = 3.725 kilograms.
Hence, the wooden part is 3.725 kilograms.
-34.68 - (-49.62) = -34.68 + 49.62 = 14.94 degrees warmer at the north pole
Answer:
D. 3x² + 19x - 14
Step-by-step explanation:
Use FOIL to find the answer.
First: x * 3x = 3x²
Outer: -2 * x = -2x
Inner: 3x * 7 = 21x
Last: 7 * -2 = -14
Form the equation:
3x² - 2x + 21x - 14
Combine like terms.
3x² + 19x - 14
Answer:
1.716*10^-3
Step-by-step explanation:
(4.4*10^-6)*(3.9*10^2)=0.001716
To convert 0.001716, we need to move the decimal places three places to the right to make sure the number is between 1 and 10. Moving three places to the right makes the exponent negative.
