The percent of the original price, the new price is given as 86.9%
<u>Solution:</u>
Given, In August, Ralph bought a new set of golf clubs that cost $565.
The cost of the clubs was marked up to $650 in October.
We have to find which proportion can be used to find what percent of the original price the new price is, if p represents the unknown percent?
The formula is normally partial/whole equals to percentage/100. In this case $565 is partial because the price increased.
So it will be,
Whenever you get results like these, you just need to round to the nearest hundredths place, which is 86.9%.
Hence, the percentage is 86.9%
ANSWER
The value of theta in the second quadrant is,
EXPLANATION
The given trigonometric equation is
This implies that,
This implies that the principal solution is
and it is an angle in the first quadrant.
But the solution we are looking for is an angle in the second quadrant.
This is given by
Answer: 0.067 litres of water
Step-by-step explanation:
The mode is:
Concentration of new solution = Moles of acid in original solution / (Volume of original solution + Volume of water added)
Assume volume of water added is w.
12 = 16 (0.2) / (0.2 + w)
(0.2 + w) * 12 = 3.2
0.2 + w = 3.2 / 12
w = (3.2 / 12) - 0.2
w = 0.067 litres of water
Answer: 21°
Step-by-step explanation:
Since angles DAE and CBE are inscribed on arc AC, they r equal
Hence angle CBE = 42°
So angle DAE = 42/2 = 21°
