Samira and tineka wrote a 4-digit numbers

samira: 8,754. tineka: 4,839.

the value of the 8 in samira' s number is how many times greater than the value of the 8 in tineka's number?

a) 10
b) 100
c) 1
d) 1000

A.

Step-by-step explanation:

The 8 in samira's is in the thousands place, that is, it represents 8000.

The 8 in Tineka's number is in the hundreds place, that is, it represents 800.

Now, clearly the 8 in Samira's number is bigger than the 8 in Tineka's number, also we have that

8000 = 800*10. Then, 8000 is 10 times 800. Therefore, the 8 in Samira's number is 10 times greater than the value of the 8 in Tineka's number.

So, the answer is A.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
