Answer:
2.9 mi
Step-by-step explanation:
The time difference t between 12.30pm and 3.30pm is 3h.
Let the distance to Marat's house be s.
The equation to calculate velocity v is given by:
v = distance / time.
Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:
3 = s/12 + 1.5 + s/2.3
Solve this equation for s:
(1/12 + 10/23)* s = 1.5
s = 2.9

<span>Best Answer: 1) Q is positive therefore the process is endothermic. .769kj+-.810kj=-.041kj
2) Heat is released meaning it is exothermic. -66.9kj+45=-21.9kj
3) 7.29kj. Endothermic.</span>
Answer:
<u>For one Necklace you would need...</u>
24 blue beads.
16 white beads.
4 green beads.
Ratio: 24: 16: 4
Step-by-step explanation:
If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.
Step 1: 6 x 4 = 24 (amount of blue beads in necklace).
Step 2: 4 x 4 = 16 (amount of white beads in necklace).
Step 3: 1 x 4 = 4 (amount of green beads in necklace).
Now check to see if the total of all types of beads sum up to 44:
Step 4: 24 + 16 + 4 = 44
______________-
There is your answer:
You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.
