Answer:
x = 4 sqrt(2)
Step-by-step explanation:
This is a right triangle so we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = 4/x
Multiply x to each side
x sin 45 = 4/x *x
x sin 45 = 4
Divide each side by sin 45
x sin 45 / sin 45 = 4 /sin 45
x = 4/ sin 45
We know sin 45 = sqrt(2)/2
x = 4/ sqrt(2) /2
x = 8/ sqrt(2)
We do not leave a sqrt in the denominator so multiply by sqrt(2)/ sqrt(2)
x = 8/ sqrt(2) * sqrt(2)/sqrt(2)
x = 8 * sqrt(2) /2
x = 4 sqrt(2)
The six sided die has 6 sides (with numbers 1,2,3,4,5 and 6). That's why the probability to roll number 2 in one trial is equal to
.If you'll dol 50 trials, then you can expect
times to roll number 2 (8 or 9 times).
A) 27, and 87 miles
B) 70,60,30
C) B=43,750, G=42,940, A=18,130
Answer:
A
Step-by-step explanation:
25.00-3.75 is 21.25. divide that by 1.25 to get exactly 17.
Answer:
Priya got it right.
Step-by-step explanation:
I wouldn't have done it the way she did, but it's still correct. You can check with a calculator (if Khan Academy allows you to) or do it like this:
If f = 4, then f ÷ 0.25 should be 16.
4 ÷ 0.25 = 16
So, Priya got it right.
