The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.

65 + 15 = 80

180 - 80 = 100 = Angle C.

It says to list them from smallest to greatest.

<B = 15, <A = 65, <C = 100

DedPeter [7]

Answer:

She needs to finish in 48.7 percent of the time it normally takes her

Step-by-step explanation:

6th grade math problem

swim 15 minutes 45 seconds

bike ride 45 minutes

She want to complete the 3 events in 70 minutes

swim + bike + run = 70

15 minutes 45 seconds + 45 minutes + run = 70 minutes

Combine like terms

60 minutes 45 seconds + run = 70 minutes

Subtract 60 minutes 45 seconds from each side

60 minutes 45 seconds - 50 minutes 45 seconds + run = 70 minutes - 60 minutes 45 seconds

run = 9 minutes 15 seconds

Her training run was 19 minutes

The percent of time she needs to take is time to finish / training run time

percent = 9 minutes 15 seconds/ 19 minutes

We need to put this in minutes. There are 60 seconds in 1 minute

9 minutes 15 seconds = 9 minutes 15/60 = 9.25 minutes

percent = 9.25 minutes / 19 minutes

percent = .486842105

percent = 48.7 percent

She needs to finish in 48.7 percent of the time it normally takes her

Determine whether these statements are true or false. a) ∅ ∈ {∅} b) ∅ ∈ {∅,{∅}} c) {∅} ∈ {∅} d) {∅} ∈ {{∅}} e) {∅} ⊂ {∅,{∅}} f )

Pavel [41]

Answer:

a) ∅ ∈ {∅} TRUE

b) ∅ ∈ {∅,{∅}} TRUE

c) {∅} ∈ {∅} FALSE

d) {∅} ∈ {{∅}} TRUE

e) {∅} ⊂ {∅,{∅}} TRUE

f ) {{∅}} ⊂ {∅,{∅}} TRUE

g) {{∅}} ⊂ {{∅},{∅}}FALSE

Step-by-step explanation:

To assess whether these statements are true or false, first observe the symbol:

"∈" means that element, as it is and as it is, belongs to the set. To belong to the set it must be within the symbols "{}"

On the other hand, the symbol "⊂" means "subset", that is, it is a subset that is included in the main set.

So:

c) is false because "{∅}" is not included in the set

g) is false because " {{∅}}" is not included in the set
