Answer:
24 inches.
Step-by-step explanation:
Given:
During a week the water level in a pond decreased by 4 in. Per day,
For two days, it decreased by half that amount = 
Question asked:
How much did the water level decrease in the pond in one week?
Solution:
As we know, there are 7 days in a week.
<u>For 5 days,</u>
Each day water level decreased by = 4 inches
In 5 days, water level decreased by = 
<u>For exceptional 2 days:</u>
Each day water level decreased by = 2 inches
In 2 days, water level decreased by = 
Water level decreased in whole week = 20 + 4 = 24 inches
Therefore, water level decreased 24 inches in the pond in one week.
Answer:
The least common mutible for 47,26, and 7 is "8554".
Check the picture below.
the triangle is an isosceles, so it has twin legs, and a base bottom.
the twin sides stem from the "vertex", and we know the vertex is 120°, and since the triangle is inscribed in a circle, because the circle is "circumscribing" it, then the base side of the triangle will be the diameter of it.
if we run a perpendicular line to the base from the vertex, we'll split the vertex in two 60° angles, as you see there, giving us a 30-60-90 triangle on each side.
so, anyhow, the rest is just a matter of using the 30-60-90 rule.
that's the diameter, and as you know, the radius is just the length of the base, or half the diameter.

Answer:
x=−2 or x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x2−2x−3=5
Step 2: Subtract 5 from both sides.
x2−2x−3−5=5−5
x2−2x−8=0
Step 3: Factor left side of equation.
(x+2)(x−4)=0
Step 4: Set factors equal to 0.
x+2=0 or x−4=0
x=−2 or x=4
