Answer:

Step-by-step explanation:
The square root of 11 is 3.31... this could be the answer.
Answer:
B is correct.
Step-by-step explanation:
Quadratic Expression (Standard Form) is:

To say it simply, the expression must have 2 as the highest degree.
This means that if there are any higher or lower degrees than 2 then they are not quadratic expression.
A choice is not quadratic expression because it has 1 as the highest degree.
B choice is correct because 2 is the highest degree.
C choice is wrong because 3 is the highest degree.
D choice is wrong because it is not a polynomial.
Therefore, B is correct.
Answer:
length = 115 cm
width = 108 cm
Step-by-step explanation:
The perimeter of a rectangular swimming pool is 446 centimeters
LEt L be the length of the pool
The width of the pool is 7 centimeters less than the length of the pool.
width = length - 7
W= L-7
Given perimeter = 446
Perimeter of rectangle = 2(length)+2(width)
446 = 2(L) + 2(W) we know W = L-7
446 = 2(L) + 2(L-7)
446 = 2L + 2L - 14
Add 14 on both sides
460 = 4L
divide by 4 on both sides
L= 115
Length L= 115
Width W = L - 7 = 115 - 7= 108
Answer:
Volume = 1330.6cm³
Step-by-step explanation:
Step one
This problem bothers on the mensuration of solid shapes a cylinder.
We know that the volume of a cylinder is expressed as
V= πr²h
Step two
Given data
Base of the cylinder /diameter = 11cm
Hence radius = 11/2= 5.5cm
Length /height of cylinder = 14cm
Step three
Substituting our given data we have
Volume = 3.142*(5.5)²*14
Volume = 3.142*30.25*14
Volume = 1330.637cm³
to 1 decimal place we have
Volume = 1330.6cm³
John should receive about 7200 milligrams of the drug.The unit conversion given is,1 lb =0.45 kg.
<h3>What is weight?</h3>
The weight of matter is found as the product of the mass and the gravitational acceleration.
Unit conversion;
1 lb =0.45 kg.
Dosage of a drug = 200 mg / kilogram
John weighs = 80 lb
1 lb =0.45 kg.
80 lb = 36 kg
According to the weight the drug should he receive is;
Dosage of a drug = 200 mg / kilogram × 36
Dosage of a drug = 7200 milli gram
Hence, John should receive about 7200 milligrams of the drug.
