Answer:

opposite side = √192 in, hypotenuse = 16in

Step-by-step explanation:

tan60 = opposite side / 8in

opposite side = √192 in

cos60 = 8in/hypotenuse

hypotenuse = 16in

Write the equation of a line parallel to line l that includes point (2,1)

olya-2409 [2.1K]

The given line goes up 3 units for every 1 unit it goes to the right, so its slope is 3. If it is made to go through point (2, 1), it will be moved 2 units to the right. This means the y-intercept will be below its current value of 1. The only appropriate choice is ...

5/6 , 7/18 , 11/24 , 19/36 in descending order

motikmotik

Answer: 5/6, 19/36, 11/24, 7/18

Step-by-step explanation:

Descending order is going from largest to smallest. We can do this by comparing the fractions. We make all the fractions have the same denominator. Then we will see which has the larger numerator.

$\frac{5}{6} , \frac{7}{18} , \frac{11}{24} , \frac{19}{36}$

A common denominator we can use is 72, since it is a common multiple.

$\frac{60}{72} ,\frac{28}{72}, \frac{33}{72}, \frac{38}{72}$

Now that all the numbers have the same denominator, we compare to see which number is largest to smallest.

$\frac{60}{72} ,\frac{38}{72} ,\frac{33}{72} ,\frac{28}{72}$

With our descending order, let's put it back into the original fractions.

$\frac{5}{6} ,\frac{19}{36} ,\frac{11}{24} ,\frac{7}{18}$

Pleasr help me ASAP! Thank you^-^ If w = 10 units, x = 5 units, and y = 6 units, what is the surface area of the figure? Round y

Sladkaya [172]

Answer:

D:456.2 units²

Step-by-step explanation:

Step 1: Area of all 4 sides of cuboid

Area of rectangle = 4 x length x breadth

Area of rectangle = 4 x 10 x 5

Area of rectangle = 200

Step 2: Calculate bottom of cuboid

Area = length x breadth

Area = 10 x 10

Area = 100

Step 3: Calculate slant height of pyramid

c² = a² + b²

c² is hypotenuse

a² is the base which is half of w (10/2 = 5)

b² is y which is 6

c² = a² + b²

c² = 5² + 6²

c = √61

Step 4: Calculate area of one face of the pyramid

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 10 x √61

Area of triangle = 5√61

Step 5: Calculate areas of all 4 faces of the pyramid

4 x 5√61 = 20√61

Step 6: Calculate the total surface area

Total surface area = 200 + 100 + 20√61

Total surface area = 456.2

The surface area of the figure is 456.2 units²

Option D is correct.
