Final answer is 1,000 yup
Answer:
Step-by-step explanation:
It's the formula of a circumference:
d - diameter
Solve for d:
<em>divide both sides by π</em>
Answer:
Length and Width = 10ft
Height = 5ft
Surface Area = 300 square feet
Step-by-step explanation:
Given
-- Volume
Let:
Volume (V) is calculated as:
Substitute 500 for V
Make H the subject
The tank has no top. So, the surface area (S) is:
Substitute 500/LW for H
Differentiate with respect to L and to W
and
Equate both to get the critical value
and
and
and
and
Make L the subject in
Substitute for L in
Cross Multiply
Divide both sides by 1000
Take cube roots of both sides
Substitute 10 for W in
Recall that:
So, the dimensions are:
and
The surface area is:
Sales tax will result an increased priced. Since the increased rate is (1 + 6%) = 1 + 0.06 = 1.06. So the price will be
$13.74*(1.06) = $14.56
Answer:
Step-by-step explanation:
tan28=h/150
h=150tan28
h=79.8ft
x/(12+8)=5/8
x/20=5/8
x=100/8
x=12.5
