Answer:

2.74feet

Step-by-step explanation:

Since we are not told what to find, we can find the height of the plywood

Given the following

length of ramp = 8feet

angle of elevation = 20degrees

Required

Height of the plywood

Using the SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 20 = H/8

H = 8sin20

H = 8(0.3420)

H = 2.74 feet

Hence the height of the plywood is 2.74feet

How many times larger is 8*10^6 than 2*10^2
bogdanovich [222]
The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 × 10^{6} - 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 × 10^{4} - 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 × 10^{6} is 7999800 times larger than 2 × 10².

kodGreya [7K]
If you would like to know what is the amount of money Yul should leave for the tip, you can calculate this using the following steps:

20% of $14.50 = 20% * 14.50 = 20/100 * 14.50 = $2.9

Result: Yul should leave $2.9 for the tip.
