<h3>
Answer: 29 miles (approximate)</h3>
======================================================
Explanation:
Segment AB is already given to be 19 miles long.
I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.
Use the law of cosines to find the missing side
a^2 = b^2 + c^2 - 2*b*c*cos(A)
a^2 = 12^2 + 19^2 - 2*12*19*cos(138)
a^2 = 843.874040417691
a = sqrt(843.874040417691)
a = 29.0495101579647
a = 29 when rounding to the nearest whole number
Side BC is roughly 29 miles long.
Standard form is using only numerical values (numbers.)
Ninety-eight = 98
six-tenth = 0.6
98 + 0.6 = 98.6
98.6 is your answer
Hope this helps
Answer:
Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.
Step-by-step explanation:
50/5 = 10 which means that 1/5 of 50 = 10.
2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.
The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
Yes because it is just milk and a substance in the milk
Perpendiculare means the slopes multiply to -1
y=3/5x+10
slope is 3/5
3/5 times what is -1
-5/3 is answer
slope of perpenduclar is-5/3 find y int
y=-5/3+b
point given is (15,-5)
x=15
y=-5
-5=-5/3(15)+b
-5=-25+b
add 25 to both sides
20=b
the yintercept is y=20 or the oint (0,20)
