The slopes of two parallel lines must be identical.
We have slope
, so the slope for the parallel line be the same.
Now, to find an equation that also passes through the given point, we use slope-point form,
, where our point
is substituted for
.
Now, we convert to slope-intercept form as such.
And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.
Answer: 29,113.2 km
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Circumference = 2 x π x radius
Replacing with the values given:
Earth's mean circumference = 2 π 6,371.0 = 40,030.2 km
Earth's moon mean circumference = 2 π 1,737,5= 10,917 km
Now, we have to subtract Earth's moon mean circumference to Earth's mean circumference:
40,030.2- 10,917 =29,113.2 km
Feel free to ask for more if needed or if you did not understand something.
Answer:
1. 10% of the bill is $138. The final bill once 10% is taken off is $1242.
2. 20% of the total is $34.10. The final total once the 20% is taken off is $136.4
Step-by-step explanation:
1. A crash repair bill comes to $1380.00. How much is 10% of the bill? What is the final bill once 10% is taken off?
To find how much is 10% of the bill, we multiply the bill by 0.1
0.1*1380 = 138
10% of the bill is $138.
To find the final bill, we subtract the initial bill by 10%.
1380 - 138 = 1242
The final bill once 10% is taken off is $1242.
2. A person buys a new fan belt, a new alternator, and a new water pump for their car. The total comes to $170.50. What is 20% of the total? How much is the final total once the 20% is taken off?
Same logic as above.
0.2*170.50 = 34.1
20% of the total is $34.10.
170.50 - 34.1 = 136.4
The final total once the 20% is taken off is $136.4
How explain please !!!!!!!!!!
