Answer:
3 * 10^6 if the answer is 3.64 * 10^6, you really ought to argue the meaning of estimate with your instructor.
Step-by-step explanation:
This is a very valuable question. Put your calculator away when you answer it. Using a calculator is sort of cheating.
1.3 * 10^3 roughly is roughly 1 * 10^3
2.8*10^3 hours is roughly 3 * 10^3
Forget the powers for now and just work with the 1 and 3
1*3 equals 3.
10^3 * 10^3 = 10^6 when the base of two numbers is the same (10 in this case) then the powers are added.
10^(3 + 3) = 10^6
So the answer is roughly 3*10^6
Now you can take out your calculator and get the answer.
1.3*10^3 * 2.8 * 10^3 = 3.64 * 10 ^ 6
Notice that the estimate (done in my head) is close enough to tell you what the answer should be. On a test, that's a very handy skill.
Answer:
The answer to your question is: y = 1/4x - 5
Step-by-step explanation:
Data
slope = m = 1/4
Point (0, - 5)
Formula
(y - y1) = m(x - x1)
Substitution
(y + 5) = 1/4 ( x - 0)
Simplification
(y + 5) = 1/4 (x)
y = 1/4x - 5 Result
Answer:
-34/-812 = 17/406
Step-by-step explanation: i think this is right...
Step-by-step explanation:
For no. 11
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 4
Also,
4y + 7 ° + 10y - 37° = 180° { being co-interior angles }
14y - 30° = 180°
14y = 210°
y = 210° / 14
y = 15°
For no. 12
5x + 38° = 8x - 19° { being opposite angles of parallelogram }
8x - 5x = 38° + 19°
3x = 57°
x = 19°
Hope it will help :)
Answer:
-4
Step-by-step explanation:
( 2 * - 2 ) + ( -4 * - 2 )
= -4 + 8
= -4
