Around $634.85 per year

Because:

$32.85+$35(12 months)+$3.5(52 weeks in a year)= Total cost per year
$420 $182

$32.85 + $420 + $182 = $634.85 per year

4. Find the value of x in the right triangle below. 60°

antiseptic1488 [7]

Answer:

Step-by-step explanation:

It is worthwhile memorizing the ratios of legs in a 30°–60°–90° triangle. Shortest to longest, the ratios are ...

1 : √3 : 2

Then the sides marked will have the ratio ...

6 : x = 1 : 2 = 6 : 12

x = 12

_____

You can also get there using trigonometry.

cos(60°) = 6/x

x = 60/cos(60° = 60/0.5

x = 12

Need help with part c

Artyom0805 [142]

First understand that this is a linear graph. Find 2 points on the graph. We can use (0,1) and (3,-3).

Look at how much the x increases, in this case the x value increases by 0+3, so 3.

Then see how much the y value increases (make sure to evaluate them in the same order) 1 + (-3) = -2.

So you know that the y value decreases by 2 units for every 3 unit increase in x. Therefore the slope is y=(-2/3)x

Then figure out what you add to the end. The y intercept is (0,1), so add 1 to the end of y=(-2/3)x to move it up.

Your resulting eq is y=(-2/3)x+1

They're usually 365 days in each year every 4th year is call a leap year and has one extra day in February how many days are the

Mariana [72]

Answer:

Total number of days in 8 years is 2,922 days.

Step-by-step explanation:

Number of days in a Normal year = 365 days

Number of days in a leap year = 366 days

Also, Leap year comes exactly ONE TIME in every FOUR YEARS.

⇒ In every consecutive 4 years, 1 year is a leap year.

⇒ So, number of leap years in 8 years = 2

Now, 8 Years = 6 Normal years + 2 leap Years

Number of days in 6 normal years

= 6 x ( Number of days in a regular year)

= 6 x (365 days) = 2,190 days

Number of days in 2 leap years

= 2 x ( Number of days in a leap year)

= 2 x (366 days) = 732 days

So, Total number of days in 8 years

= Number of days in 6 regular years + Number of days in 2 leap years

= 2,190 days + 732 days

= 2,922 days

Hence, total number of days in 8 years is 2,922 days.
