NEED HELPPP!! 18 19 and 20 PLEASEEEE URGENT
Yanka [14]

Answer:

18. 368 students

19. 16

20.

Step-by-step explanation:

18.

students : faculty

23:5

x : 80

in total, there are 23+5 parts = 28 parts

5/28 = 80 faculty members

so 23/28 = x students

so use the find for one method.

If 5/28 = 80, then

80/5 = 1 member

so to find for 23 members,

80/5 × 23

=368 students

19. 640/40 = 16

20.

h = height of tree

h = 8.5 shadow

3 = 3.75 shadow

If 3.75 = 3

then 1 ft shadow = 3/3.75

then 8.5 ft shadow = 3/3.75 × 8.5

=6.8 ft tree.

proportion: 3/3.75 = h/8.5

answer: 3/3.75 = 6.8/8.5

I need the answer to this
aleksandr82 [10.1K]

Answer:

50

Step-by-step explanation:

All three angles of a triangle will add up to 180. Since one angle is known, 90, the right angle, and another is known, 40, we can solve for the missing angle.

90 + 40 + x = 180

Add like terms.

130 + x = 180

Subtract 130 from both sides.

x = 50

The missing angle is 50.
