The percentage increase from 5 laps of race on the first day to 9 laps after several weeks is 80%
<h3>How to determine the percentage increase?</h3>
The distance ran are given as:
Initial = 5 laps
Final= 9 laps
The percentage increase is calculated using:
Percentage = (Final - Initial)/Initial
So, we have:
Percentage = (9 - 5)/5
Evaluate
Percentage = 0.8
Express as percentage
Percentage = 80%
Hence, the percentage increase is 80%

Answer:
x = 40
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20)
8(8 + x) = 12 × 32 = 384 ( divide both sides by 8 )
8 + x = 48 ( subtract 8 from both sides )
x = 40
3x + 4(x + 1) = 67
7x + 4 = 67
7x = 67-4 = 63
x = 9
The smaller integer is 9.
Step-by-step explanation:
<h3>Vocabulary (what the words mean):</h3>
Divide, the same as ÷
divide 6 <u>by</u> 3
<u>by</u> is the same as the symbol
6 ÷ 3 = 2
Difference, This is another way of saying take away or minus
the difference of 6 and 3 is
6 - 3 = 3
Product, This is another word for multiply or times
the product of 2 and 3 is
2 × 3 = 6
<h3>Write as an equation</h3>
divide <em>(÷)</em> the difference of 20 and 6 <em>(20 - 6)</em> <u>by</u> the product of 7 and 2 <em>(7 × 2)</em>
<em />
<em>so </em>
<em>(20 - 6) ÷ (7 × 2)</em>
<em />
<em>can you do the rest???</em>
Answer:
C.
Step-by-step explanation:
-a + b = -2
b = a + 3
-a + a + 3 = -2
3 = -2 (incorrect).....no solutions.....because these lines are parallel
