I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y
Answer:
x=13 and y=sqrt338
Step-by-step explanation:
so basically the opposite of one of the 45 degrees is 13 so the other 45 degrees is 13 too and you find pythagorean theorem of the other one
We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
Answer: 137 cans are left of cola.
Step-by-step explanation: First we want to find the total amount of cola Trey bought. Each pack contains 8 cans, so multiply 18 packs by 8 cans to find the total amount of cans he bought. 18 x 8 = 144 total cans of cola.
Since Trey drank 7 of the cans, simply subtract 7 from 144, 144 - 7 = 137 total cans of cola remaining.
Answer:
This is an geometric sequence with a common ratio <em>r</em> of 1/2
Step-by-step explanation:
When you find out <em>r</em>, you realize the ratio between the numbers to be dividing by 2, or 1/2. Since it is <em>r</em> and not common difference <em>d</em>, it is an geometric sequence.
