Anticent math problem how many rabbitsand phesants 35 heads and 94 feet

Mathematics
1 answer:
lora16 [44]3 years ago
5 0

If all were pheasants, there would be 35 pairs of feet. There are 47 pairs of feet, so there must be 47-35 = 12 rabbits. Each rabbit has one more pair of feet than a pheasant does.

There are 12 rabbits and 23 pheasants.

_____

If you insist on equations, you can let p and r represent the numbers of pheasants and rabbits, then write ...

... p + r = 35

... 2p + 4r = 94

Divide the second equation by 2 and subtract the first:

... (2p +4r)/2 - (p +r) = (94)/2 - (35)

... r = 12 . . . . . . . . . . . simplify

... p + 12 = 35 . . . . . . use the value of r in the first equation

... p = 23 . . . . . . . . . . subtract 12

(p, r) = (23, 12)

A regular hexagon has sides of 3 feet. What is the area of the hexagon?
frosja888 [35]

Answer:

13.5\sqrt{3}\:\text{ft}^{2}

Step-by-step explanation:

Given: The side of a regular hexagon is 3 feet.

To find: Area of the hexagon

Solution:

It is given that the side of a regular hexagon is 3 feet.

We know that the area of a regular hexagon whose side is a units is \frac{3\sqrt{3} }{2} a^{2}

Here, the side is 3 feet

So, area of the regular hexagon

=\frac{3\sqrt{3} }{2} \times3^{2}

=\frac{3\sqrt{3} }{2} \times9

=\frac{27\sqrt{3} }{2}

=13.5\sqrt{3}\:\text{ft}^{2}

Hence, area of the regular hexagon is 13.5\sqrt{3}\:\text{ft}^{2}

Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti
julsineya [31]

Answer:

see below

Step-by-step explanation:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage

After first dose residual drug amount is:

  • d= 500*0.045= 22.5 mg

After second dose:

  • d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum residual drug will be in the body:

  • d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

  • 500+19*22.5= 927.5 mg
