Answer:I can solve it?
take away 11 from both sides to make..
4x = 4
simplified (4 ÷ 4) to make x=1
Step-by-step explanation:
The answer is going to be 41
Answer:
dy/dt = - (1/5) ft/s = - 0.2 ft/s
Step-by-step explanation:
Given
L = 5 ft
Qin = 25 ft³/s
Qout = 30 ft³/s
h = 10 ft
dy/dt = ?
We can apply the relation
ΔQ = Qint - Qout = 25 ft³/s - 30 ft³/s
⇒ ΔQ = - 5 ft³/s
Then we use the formula
Q = v*A
where Q = ΔQ, A = L² is the area of square base and v = dy/dt is the rate of change in the depth of the solution in the tank
⇒ ΔQ = (dy/dt)*L²
⇒ dy/dt = ΔQ/L²
⇒ dy/dt = (- 5 ft³/s)/(5 ft)²
⇒ dy/dt = - (1/5) ft/s = - 0.2 ft/s
Answer:
19,200 yds²
Step-by-step explanation:
The question is asking for how many <em>square yards</em> of grass is needed
This means that it is looking for the Area.
The formula for area is <em>Length x Width = Area</em>
<em>120</em> (Length)
<em>160</em> (Width)
<em>120 x 160</em> = 19,200
The unit of measurement is yards...
19,200 yds²
