Answer:
AC : BC = 22 : 33 = 2 : 3
Step-by-step explanation:
It is convenient to find the value of x first.
AB/AC = 1/2 = (3x -4)/(2x +12)
Cross-multiplying gives ...
2x +12 = 2(3x -4)
2x +12 = 6x -8
20 = 4x . . . . . . . add 8-2x to both sides
5 = x . . . . . . . . . . divide by 4
___
So the side lengths are ...
- AB = 3x -4 = 3·5 -4 = 11
- AC = 2x +12 = 2·5 +12 = 22
- BC = 7x -2 = 7·5 -2 = 33
Then the ratio of interest is ...
AC : BC = 22 : 33
AC : BC = 2 : 3 . . . . . . (divide by 11 to simplify)
_____
<em>Comment on the triangle</em>
We note that AB+AC=BC, so this "triangle" is actually a line segment 33 cm long.
Answer: 30
Step-by-step explanation:
Given :The weight of a bag of golf balls varies directly as the number of golf balls in the bag.
Let x be the number of golf balls in a bag that weighs 1,110 grams.
Then we have the following direct variation equation,
Multiply 1110 both sides , we get
Hence, there are 30 balls in the bag.
The 3rd questions answer is: In order to solve this, you need to add 20% of the $7.50 TO the $7.50.
First, multiply 0.20 x $7.50 = $1.50
Then, add the $1.50 to the original $7.50 because the price is increasing by 20%, so the new price of the ticket is $9.00. (I got this answer because someone else asked this question on BRAINLY and this was an answer, it’s correct btw)
The answer is B because the first number in those points don’t repeat but all the other ones have the first number repeating
Answer:i think its 180
