1. The hiker's elevation after 6 minutes was 30 feet!
E- Each minute for 6 minutes, 10*60 is 60, -30+60 is equal to 30!
2. Taylor answered 9 questions incorrectly.
E-If you do, 0.8*45, the answer is 36, which means Taylor answered 36 questions CORRECTLY. 45-36 is 9.
3. Lauren will bike 20 miles in one hour.
E- 1 hour=8/8 hours. 2*8 is 16. 1/2 times 8 is 4. 16+4=20! You can also do 2 1/2= 2.5. 2.5*8 which is 20.
4. 13 full rows
E- 2/3 of 20, or 2/3*20 is 13 1/3. Since it asks for full rows, they filled 13 rows.
5. 1 1/4.
E- Just add it.
6. Selling price is $20.4
E- 12*0.7 is 8.4. So since they mark UP, add 8.4 to 12, and you get 20.4.
7. 5x-1
E- Look at screenshot.
8. Option 4/D or 0.63 (repetition bar over the 3)
E-Just divide and you get the answer 0.63 (etc)
9. 12 equal pieces are created.c
E- Divide 3/4 by 1/16 and you get 12.
10. 6x+2 is the perimeter
E- I don't know how to explain, just solve!
11. 76.62 was the original price.
E- 0.3*58.94 is 17.68. Since the sneakers WERE marked down that much, add that to the new amount. 58.94+17.68 is 76.62.
Brainliest please!
12. -0.7

Answer:
Step-by-step explanation:
In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2
In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2
In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2
89 + 2y^2 = 13^2 = 169
2y^2 = 169 - 89 = 80
y = 80/2 = 40
so
