Answer: B
Step-by-step explanation:
We are given that a 45-45-90 triangle has a hypotenuse of 
.
In a 45-45-90 triangle, the legs are congruent. Therefore we can use the Pythagorean Theorem to solve.
[combine like terms]
[square root both sides]
[divide both sides by root 2]
Now, we know that a leg is length 7, which is B.
Answer:
- Burgers - $8.29 and fries - $4.39
Step-by-step explanation:
<u>Let burgers - b, fries - f</u>
- 8b + 3f = 79.49
- 12b + 6f = 125.82
<u>Double the first equation and subtract the second equation:</u>
- 16b + 6f - 12b - 6f = 2(79.49) - 125.82
- 4b = 33.16
- b = 33.16/4
- b = 8.29
<u>Find f:</u>
- 8(8.29) + 3f = 79.49
- 3f = 79.49 - 66.32
- 3f = 13.17
- f = 13.17/3
- f = 4.39
2-1=1
hope it helped the answer is 1
Ok, so basically, the amount of orange pics is 3/5.
I think better w/ visuals, so i drew 5 circles, and colored 3 orange
Since the 3 circles represent 12 picks (because there are 12 picks total and 3/5 of the picks are orange) you nee to find out how many picks 1 circle represents.
In order to find this, do 12/4=3
One circle equals 3 picks
multiply 3 by 5, and you get 15
Hope this helps because this is a better explanation for visual learners!
