Answer:
Every time Megan takes a sip of water,
the level of the water in her glass goes
down 1 inch. She takes 3 sips. How much
did the level of the water in Megan's
glass change? it changes 3 inches
Step-by-step explanation:
beacuase if one sip is on inch down so 3 sips it gonna be 3inches

For a better understanding of the solution provided here please find the diagram in the file that has been attached. As shown in the diagram, the sea level is taken as the "zero level" thus making 35 feet below sea level as -35 and making 2 feet above (or in the air) as +2 (or simply 2).
The fish was at P1 (35 feet below sea level or, -35) to start with and jumped to P2 (2 feet above sea level, or 2), so the total distance travelled by the fish is the distance between the positions of P1 and P2 which can be shown as:
feet.
Therefore, the fish travelled a total of 37 feet from it's previous position which was 35 feet below the sea level.
Answer: option D
Step-by-step explanation:
To get equivalent expression we need to remove the parenthesis
multiply negative sign inside the parenthesis
when we multiply negative and negative it becomes positive.
So the expression becomes
So, option D is the equivalent expression
Answer: Choice B
Building A; it is around 50.34 feet taller than building B
======================================================
Explanation:
Draw two right triangles such that they both have a reference angle of 40 degrees. Since it's an angle of elevation, place the angle near the horizontal side.
Opposite each reference angle is the height of the building, which we'll call h.
The adjacent side is the horizontal distance from the person to the building.
Building A is 120 ft away so it's height is...
tan(angle) = opposite/adjacent
tan(40) = h/120
h = 120*tan(40)
h = 100.69
This value is approximate. Make sure your calculator is in degree mode.
-----------------
Repeat the same idea for building B, except the adjacent side is smaller this time.
tan(angle) = opposite/adjacent
tan(40) = h/60
h = 60*tan(40)
h = 50.35
This value is approximate.
-----------------
Now subtract the heights
100.69 - 50.35 = 50.34
This shows that building A is roughly 50.34 taller than building B.
Answer:
You can use a ratio to solve this problem. Use x as a variable for the cups of food in 28 days.
1 (day): 3 (cups)
28 (days): x (cups)
Cross multiply.
x=28(3)
x=84
So, Li’s dog eats 84 cups of food in 28 days.
