Answer:
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday
Friday
Monday
Step-by-step explanation:
The given amount of gallons is in decimal form and we have to arrange the numbers in the order from least to greatest.
4.5 is the largest number in the given numbers.
Then comes 4.252 and 4.255
As 0.252<0.255 so 4.252 will be smaller.
The smallest number is 3.6
Arranging the numbers, we get
3.6
3.71
4.252
4.255
4.5
Now arranging the corresponding day to each number,
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday
Friday
Monday
Answer: The trip should take 3.5 hours.
Step-by-step explanation: To find the time, divide the distance by the rate. In this case, 210/60 = 3.5.
Answer:
7(m + 2)
Step-by-step explanation:
1) <em>Add the numbers</em>
- 3 + 2m-1 + 5m + 12
- 14 + 2m + 5m
2)<em> Combine like terms</em>
3) <em>Rearrange terms</em>
4) <em>Common factor</em>
<em />
- <em>Factor by grouping</em>
- 3 + 2m - 1+ 5m + 12
- 7m + 14
- <em>Factor by grouping</em>
⇒ 3 + 2m - 1 + 5m + 12
⇒ 7(m + 2)
Solution:
Now, let's say, we add "x" lbs of the 60% gold alloy, so.. how much gold is in it? well, is just 60%, so (60/100) * x, or 0.6x.
likewise, if we use "y" lbs of the 40% alloy, how much gold is in it? well, 40% of y, or (40/100) * y, or 0.4y.
now, whatever "x" and "y" are, their sum must be 12.4 lbs.
we also know that the gold amount in each added up, must equal that of the 50% resulting alloy.
how much of the 40% alloy? well, y = 12.4 - x.
Answer:
E. 1/2
Step-by-step explanation:
Divide by 2, then make use of the Pythagorean identity for sine and cosine.
sin(x)^2 +cos(x)^2 = 2a
1 = 2a . . . . . . . sin²+cos²=1
1/2 = a
