Mathematics
1 answer:
Liono4ka [1.6K]3 years ago
4 0

Answer:

Yes by SAS

Step-by-step explanation:

if you do 42 / 18 you see that the relationship between the sides is 2.3333... so that is one proportional side

Then, you see that there is one angle in both triangles that is 76 degrees, so that is one equal angle

then, you can do 21 / 9 = 2.33333... which is the same as the first proportion which means that is another proportional side.

then you have a side, angle, and a side, so it's SAS

If Sophie traveled 25 feet in 3 seconds, how fast was she traveling in miles per minute(5280 feet in a mile)
Oksanka [162]

Answer:

0.095 miles per minute

Step-by-step explanation:

If Sophie traveled 25 feet in 3 seconds, then in 1 second she will travel

25/3 = 8.333 ft

But in 60 seconds make 1 minute, so in 1 minute, she will travel

(25/3) × 60 = 25 ×20

= 500 ft

Therefore in miles/minute, she was going

500/5280 = 0.095 miles per minute

5 Select the correct expressions. Which expressions are equivalent to 3x + 2(x - 1) - 4? 3x + 2x - 2 - 4 5x - 6 3(x-4) 3(x + 2)
beks73 [17]

Your question is a bit unclear, but I will try to answer it anyway.

The expression 3x + 2(x - 1) - 4 simplified is:

3x + 2(x - 1) - 4

= 3x + 2x - 2 - 4

= 5x - 6

I cannot tell what the answers are but I am guessing they are these?:

A) 3x + 2x - 2 - 4

B) 5x - 6

C) 3(x - 4)

D) 3(x + 2) - 6

E) 6(x - 1)

Answer A is one, and so is answer B. If I read your question accurately.

I hope I helped!
