Answer:1 pretzel is 0.75$
1 soda is 0.55$
Step-by-step explanation
suppose
soda=x
pretzel=y
according to Juan
x+2y=2.05.....................(1)
according to Keisha
2x+y=1.85........................(2)
multiply 2 to the 1 no. and do subtraction from 1 no. to 2 no.
2x+4y=4.1
2x+y =1.85
<u>(-)(-) (-) </u>
3y=2.25
y=2.25/3
y=0.75
place y=0.75 to 1 no
x+2×0.75=2.05
x=2.05-1.5
x=0.55
48v^2x^5 is my answer. Hopefully I'm right :) good luck!
Answer:
Can you be a litte more specific
Step-by-step explanation:
Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.
Answer:
4 meters
Step-by-step explanation:
Let the height at which the top of the ladder is be represented by h. The sketch of the question forms a right angled triangle. So that applying the Pythagoras rule,
=
+ ![/Adj 2/^{2}](https://tex.z-dn.net/?f=%2FAdj%202%2F%5E%7B2%7D)
=
+ ![3^{2}](https://tex.z-dn.net/?f=3%5E%7B2%7D)
25 =
+ 9
= 25 - 9
= 16
⇒ h = ![\sqrt{16}](https://tex.z-dn.net/?f=%5Csqrt%7B16%7D)
= 4
Therefore, the height at which the top of ladder is placed is 4 meters.
