Answer:
c = 1.05p
Step-by-step explanation:
the price of the hat before the increase was 100%, after the increase it becomes 100 + 5% = 105%. Representing it as a decimal becomes 1.05p
Let illustrate with an example.
The price of a hat was $100, after the 5% increase. the cost of the hat becomes
100 + (0.05 x 100) = 105
To find the percentage increase
divide 105 by 100 and subtract 1
(105/100) - 1 = 1.05
It looks like he used the distributive property. He multiplied 7*2. Then. 7*6. Then he multiplied them together. That is not how you multiply numbers
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
