Answer:
2.75 m²
Step-by-step explanation:
From the information given:
the thickness of the paint = 0.07 cm = (0.07/100) m
= 0.0007 m thick
the diameter hemispherical dome = 50 m
∴
radius of the dome = 50m /2 = 25 m
The volume of a hemispherical dome is expressed as:
Thus, the change in the volume now is:
∴
dV = 2π × (25)² (0.0007)
where;
dr = 0.0007
dV = 2π × (25)² (0.0007)
dV = 2.75 m²
√81 =9
it is an odd, whole, rational number.
Answer:
No
Step-by-step explanation:
3/8 is less than 1
For a fraction to be greater than 1 the numerator, the top number, would have to be larger than the denominator, the bottom number.
ex. 3/2 = 1.5
3/8 = 0.375
Answer:Expression after xweeks AMOUNT =$12*x
Step-by-step explanation:since Joseph puts $12 per week then what's left is to multiply the amount by an unknown letter which will be used to represent number of weeks
First of all, rewrite
And divide both sides by 16 to get
The solution is
Which, using the suggested formula, we can compute as
Which evaluates to about - 0.20752..
