Answer:
Mallory flew in total 10,000 miles, rounded :D
Step-by-step explanation:
<em>Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:</em>
3,720 + 5,985 = 9,705 miles
<em>then, we have to round thefirst digit to the right following this rule</em>
0-4 is rounded down
5-9 is rounded up
<em>now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)</em>
9,705 >>> rounding it up >>> 10,000
Let me know if you have any questions XD
Answer:
the answer would be 3.1 hours.
Step-by-step explanation:
Graph the equation.
Put all the answers in graph like
x=1.6
x=3.1
x=14.4
x=19.6
Now the question asks when the first tide is expected to reach a depth of 12 meters
So put y=12 because y is water level in METERS as it says in the question
and you can clearly see that 3.1 crosses answer.
Here is a photo of the the graph (Desmos)
Good luck on your other work boys!
Edgenuity is trash
Let s represent the measure of the second angle.
The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).
The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).
The sum of these angles is 180°, so we can represent the sum as
... (s-15) + s + (45+s/2) = 180
Collecting terms, we have
... 2.5s +30 = 180
... 2.5s = 150 . . . . . . subtract 30
... s = 150/2.5 = 60 . . . . divide by the coefficient of s
The first angle is 60-15 = 45.
The second angle is 60.
The third angle is 45+60/2 = 75.
_____
<u>Check</u>
The sum of the three angles is 45 +60 +75 = 180.
Answer:
C. 35
Step-by-step explanation:
I just went through all the numbers, multiplied them by 2, because you start with x which is 50, and the goal is to get to 120 with 50 and a number multiplied by two, so I tried 35 which would be 70 when multiplied by two, then added 50, which would make 120.
