Answer:
C - 5/12 of a foot
Step-by-step explanation:
Subtract the numerators from 8/12 - 3/12 - keeping the denominator
8 - 3 = 5
5/12
Answer:
x = 42
y = 38
Step-by-step explanation:
for y:
there is a corresponding angle at 58° so y + 20 must equal to 58. ∴y = 38°
for x :
first locate the straight angle at CD. The angle opposite 58° must also be 58° as it is vertically opposite. We have two values here.. 58° and 22°. Use your knowledge of straight angles and add 22 + 58, which equals to 80. Now subtract from 180 which = to 100°. We know that the angle sum of a Δ is 180° so add 38 and 100, which will give you 138°. Subtract from 180 to give you a total of 42°
Sorry if this was very lengthy haha
hope it helps:)
Answer:
- 23
- 6
- 25
- 30
- 11
Step-by-step explanation:
For these problems, you need to know that the sum of segment lengths on a line is the length of the line. You also need to know that a midpoint divides a segment into two equal parts.
1. JH = JI +IH = 12 + 11
JH = 23
__
2. KJ = JI
6 = JI
__
3. The distance between two points on a number line is found by subtracting the number at the left end from the number on the right end.
SU = U - S = 10 -(-15)
SU = 25
__
4. TV = V - T = 25 -(-5)
TV = 30
__
5. RS +ST = RT
RS + 2 = 13
RS = 11
I would put the equation into two fractions to make a proportion.
30/24 = 20/x
From there, you'd cross multiply to get:
30x = 480
x = 16
So, if there are 20 children currently in the elevator, 16 adults can still enter.
