Answer:
10%
Step-by-step explanation:
Using the given formula with the given data, we have ...
efficiency = output work / input work
= (10 J)/(100 J) = 0.10 = 10%
Answer:
63
Step-by-step explanation:
3×9= 27
4×9= 36
27+36= 63
Answer:
x = 9
Step-by-step explanation:
If ΔMNO ≅ ΔPST, their corresponding sides must also be ≅(congruent).
NO is corresponds to TS, thus sides NO and side TS are ≅.
=> 20 = 3x - 7
=> 3x = 27
=> x = 9
Answer:
y = 4x + -3
Step-by-step explanation:
1. Write the formula for slope y = mx + b
2. Find a point anywhere on the graph and use rise over run. Find slope by counting how many times you rise up.
3. You rose 4. The variable m is for the slope of a line so fill in the number 4. y = 4x + b
4. The variable b represents the y intercept and the y intercept is where the line crosses over the y axis. So that would be -3
5. Fill in the variable b with -3
6. Finally you would have y = 4x + -3
Hope this is right and hope this helps in the future!
