Are 8/12 equivalent to 4/6 explain why

Answers

Answer 1
Answer: Yes because when the lower form of 8/12 is 4/6. Try to divide 8/12 by 2
 
Answer 2
Answer: Yes. times 4 by 2, and 6 by 2. It equals 8/12'ths. Alternatively, you can do 8/12 divided by two, and you'll got 4/6, or divide again by two, to get 2/3

∠1 and ∠2 form a linear pair. If m∠1 = 5x + 9 and m∠2 = 3x + 11, find the measures of both angles.

Answers

Answer:

∠1 =109

∠2= 71

Step-by-step explanation:

if they are a linear pair that means they must both (when added together) equal 180 degrees, so this means we can add them and set them equal to 180!

8x+20=180

8x=160

x=20

then we just input them!

m∠1 = 5(20) + 9 = 109

m∠2 = 3(20) + 11 = 71

assuming you mean SURFACE area

look at shape
fold it out or whateveryo yo like
we see that the faces are
4 triangles
4 rectangles in midddle
4 more triangles on other side


calculate areas
area of triangle=1/2bh
area of rectangle=bh

leftmost side

b=2
4*1/2*2*1.8=7.2 cm^2

middle recangles

other triangles

b=2
h=2.71
total area=4*1/2*2*2.71=10.84cm^2
add them up

7.2cm^2+24cm^2+10.84cm^2=42.04cm^2

The distance in miles that you can see to the horizon is a radical function that depends on the height (in feet) that you are above the ground. If you can see a distance of 5 miles, how many feet are you from the ground?

Answers

Answer:

16.67 feet from ground

Step-by-step explanation:

Given

d= √( 1.5h) --- missing from the question

d \to distance

h \to height

Required

Determine the height when distance = 5 miles

This implies that:

d = 5

So, we have:

d= √( 1.5h)

5 = \sqrt{1.5h

Take square roots of both sides

5^2 = 1.5h

25 = 1.5h

Divide both sides by 1.5

(25)/(1.5) = h

h = (25)/(1.5)

h = 16.67
