Reil [10]

Answer:

150

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360. Let x be the unknown angle

30+70+110+x = 360

Combine like terms

210 +x = 360

Subtract 210 from each side

210+x-210 = 360-210

x = 150

Line L passes through the points (0, --3) and (6,9).<br> (a) Find the equation of line L.

valentina_108 [34]

Step-by-step explanation:

Given points are :

$(0,\:-3)=(x_1,\:y_1) \:\&\: (6,\:9)=(x_2 ,\:y_2)$

Equation of line in two point form is given as:

$\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -( - 3)}{ -3 -9 } = \frac{x -0 }{0 -6 } \\ \\ \therefore \frac{y + 3}{ -12} = \frac{x }{ -6 } \\ \\ \therefore \frac{y + 3}{ 2} = \frac{x }{1} \\ \\ \therefore \: y + 3 = 2x \\ \\ \huge \red{ \boxed{\therefore \: 2x - y - 3 = 0}} \\ is \: the \: required \: equation \: of \: line.$

Find the length of the hypotenuse of a right triangle whose legs are 5 and √2.

Blizzard [7]

Answer:

$\sqrt{27}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let h represent the hypotenuse, then

h² = 5² + ( $\sqrt{2}$ )² = 25 + 2 = 27 ( take the square root of both sides )

h = $\sqrt{27}$ ← exact value

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate

Troyanec [42]

The estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C

<h3>Total cost</h3>

This is the summation of all units cost of items or the results of adding all cost(fixed and variable)

Cost of movies = $3.75

= $4.00 to the nearest dollar

Cost of snacks (drinks, popcorn, candy bars) = $1.89 each

= $2.00 to the nearest dollar

Cost to rent 3 movies and buy popcorn, a soda, and a candy bar.

Total cost = (Cost of movies × number of movies) + cost of popcorn + cost of soda + cost of candy bar

= (4 × 3) + 2 + 2 + 2

= 12 + 2 + 2 + 2

= $18

Therefore, the estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C
