Answer: C is about 100.53
Explanation:
C=2πr
C=2(3.14)(16)
C is about 100.53
310,763,136 in word form:
three hundred ten million, seven hundred sixty-three thousand, one hundred thirty-six
Answer:
x+2y=2
-1x+1y=5
Step-by-step explanation:
Any system whose equations have the following characteristic
x+2y=2
-1x+1y=1
Is equivalent to the original system, since the differ in a number, the first equation is divided by 2 and the second by 5, we can say any system is equivalent to the original when it is escalated by a factor between its functions.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.

Cos( 30 ) = 19√3 / x
√3 / 2 = 19√3 / x
Simplify √3 from both sides
1 / 2 = 19 / x
Multiply both sides by x
1 /2 × x = 19 / x × x
x / 2 = 19
Multiply both sides by 2
x / 2 × 2 = 19 × 2
x = 38
_____________________________
Sin( 30 ) = y / x
1 / 2 = y / 38
Multiply both sides by 38
38 × 1 / 2 = 38 × y / 38
38 / 2 = y
19 = y
y = 19
