Answer:
when adding you just line the decimals up like this, let's say you had to add 1 to 2.58.
2.58
+ <u> 1 .00</u>
3.58
when multiplying you might have to move it, say you had to multiply 1.5 by 2.2. (you don't have to line up the decimals like with addition)
1 .5
<u> </u><u>×</u><u> 2.2</u>
30
<u> </u><u>+</u><u> 300</u>
3.30
1.5 has one decimal place and 2.2 also has one decimal place so you put those 2 decimal places in your answer.
sorry if this is a bit confusing lol
Formula for the circumference of a circle:
C = πd or C = 2πr
[C = circumference π(pi) d = diameter r = radius(half the diameter)]
You know:
d = 5 feet
and you're using 3.14 for π, so substitute/plug it into the equation
C = πd
C = (3.14)(5)
C = 15.7 feet Your answer is B
(4,-3) i took the test i'm 100% sure
i hope i helped ;)
Answer:
1) C) sin(θ) = 119/169
2) D) cos(θ) = 120/169
Step-by-step explanation:
The mnemonic SOH CAH TOA expresses the relationships you need for answering these questions.
Sin(θ) = Opposite/Hypotenuse = 119/169 . . . . . problem 1
Cos(θ) = Adjacent/Hypotenuse = 120/169 . . . . problem 2
Answer:
14% were running backs 43/50 were not running backs
Step-by-step explanation:
0.14=14%
