For this problem, you would use the Pythagorean Theorem (a^2 + b^2 = c^2)
A and B are the length and width of the triangle. The triangle is created by the diagonal line splitting the computer screen. C is the hypotenuse, which is the diagonal line, and will always be the longest side of the triangle.
When we plug in the numbers into the formula, we would get this:
13^2 + b^2 = 15^2
B is the unknown variable in which we are trying to find.
First, you square 13 and 15:
169 + b^2 = 225
Then, subtract 169 from both sides:
b^2 = 56
Finally, find the square root of both sides:
b = 7.483314774
Simplify to the nearest tenth, and the answer is 7.5<span />
Sec is 1/cos so sec -120 is 1/cos -120 which is -2
Answer: B
$10,390.75
Step-by-step explanation:
Given that the lease = $291 per month
Lease pay = 291 × 24 = $6984
Time = 24 months
down payment = $458.
The lease allows for 12,000 miles per year and includes a $0.35 per mile charge for miles driven in excess of that amount.
For the car to be driven a total of 32,425 miles.
Excess = 32425 - 24000 = 8425 miles
Charges = 0.35 × 8425 = $2948.75
The cost for two years for this vehicle will be
2948.75 + 458 + 6984 = $10390.75
Use a calculator. I would walk you through it, but it should be simple.

The equation representing the given statement is ~
The least number of lawns that he can cut and buy the computer is 10 lawns ~

Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
- total number of lawns cut × $50
total savings is equal to ~
hence,
by solving for " x (number of lawns cut) " we get ~
Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is
