Answer:

<em>The volume of pyramid B is 3 times bigger than the volume of pyramid A</em>

Step-by-step explanation:

<u>Proportions</u>

The proportion or ratio between two quantities a and b is the result of the division a/b.

The ratio is greater than 1 if a>b, less than 1 if a<b and exactly 1 if a=b.

We are told the volume for 3-D polyhedra A is 200 cm^3 and the volume for 3-D polyhedral B is 800 cm^3. Computing the ratio:

\displaystyle r=\frac{800}{200}=4

This means the volume of pyramid B is four times the volume of pyramid A, but that is not the answer to the question. We must say how many times B is bigger than A.

The relation obtained by the computed ratio is B being 4 times A, it means it's 4A - A = 3A

The correct answer is: The volume of pyramid B is 3 times bigger than the volume of pyramid A

Answer:

B.    l = (S - πr^2) / πr

Step-by-step explanation:

S = πrl + πr^2 solve for l

πrl = S - πr^2

  l = (S - πr^2) / πr

Answer is B.    l = (S - πr^2) / πr

Tomtit [17]

Answer:

Six

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}

(c) Banana flavouring

V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL }

2. Calculate the total volume

Chlorpheniramine = 100  mL

Lidocaine               =   59

Banana flavouring =  <u>   2.5    </u>

TOTAL                    =  162 mL

3. Calculate the number of doses

\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}\\\\\text{You can't take a fraction of a dose, so the there are $\large \boxed{\textbf{16 doses}}$}

The weight of water is 62 1/2 lb per cubic foot. Water that weighs 350 lb will fill how many cubic​ feet?
valentinak56 [21]

The question is worded incorrectly.  It should say the DENSITY of water is 62 1/2 lbs per cubic foot.  Divide the weight by the density to get volume.

(150 lbs) / (62.5 lbs/ft3) = ? ft3 (the two 3's are exponents. so it'd be ft then an exponent of 3.)
