Answer:
D) It is doubled
Step-by-step explanation:
Regardless of the side length, if the area of a square is quadrupled, the side lengths get doubled, as shown in the diagram. If all of the side lengths are doubled, that means the perimeter is also doubled.
Answer:
Step-by-step explanation:
volume of concrete=162×12×4/12=648 ft³
Answer:
The constant of proportionality is 5/3
Step-by-step explanation:
3 * k = 5
k = 5/3
Check
9 * k = 15
9 * 5/3 = 15
3*5 = 15
15 =15
The constant of proportionality is 5/3
Answer:
- <u><em>option C) 1.61</em></u>
Step-by-step explanation:
The question is to evaluate the natural logarithm of 5. Natural logarithms are logarithms with base <em>e</em>.
<em>e</em> is the irrational number equal to 2.71828182845904523536028747 ... (being irrational the decimals do not end and do not have a repetition period).
Logarithms are evaluated using tables or scientific calculators.
ln (5) = 1.6094379... it is also an irrational number, so it has infinite decimals with no repetition period.
So, rounding to two decimal numbers, ln (5) = 1.61, which is the option C).
28 / 49
divide by 7 at top and bottom
(28/7) / (49/7)
4 / 7
