Answer:

son is 12

dad is 36

Step-by-step explanation:

Say the son is x years old.

Then the father is 3x. Also 3x+x must be 48.

So 4x = 48 => x= 48/4 = 12

Let x be how old the son is. We know that the dad is 3 times older and their sum is 48. Creating an equation to represent this situation gives us:

$x+3x=48$

$4x=48$

Divide both sides by 4

$x=12$

The son is 12 years old, but we want to find the age of the dad. Since we know the dad is 3 times older, multiply 12 with 3

$12 \times 3 = 36$

The dad is 36 years old. Let me know if you need any clarifications, thanks!

Marta_Voda [28]

Answer:

1 tablet

Step-by-step explanation:

Data provided in the question:

The dose of the Uniphyl = 5 mg/kg

Strength of the Uniphyl = 400 mg per tablet

Weight of the patient = 76 kg

Now,

The recommended dose for the patient

= Dose of the Uniphyl × weight of the patient

= 5 mg/kg × 76 kg

= 380 mg

Therefore,

The number of tablets to be administered to the patient

= $\frac{\textup{Recommended dose for the patient}}{\textup{Strength of the Uniphyl}}$

= $\frac{\textup{380}}{\textup{400}}$

= 0.95 ≈ 1 tablet

Hence,

The number of tablets to be administered to the patient is 1

In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a ma

bagirrra123 [75]

Answer:49 sec

Step-by-step explanation:

Given

Maximum speed to reach is 183.58 mi/h

Length of course is 5 mi

acceleration rate is defined by 60mi/h in 4 sec

therefore acceleration(a) $=\frac{v-u}{t}$

$a=\frac{60\times 60\times 60}{4}$

$a=54\times 10^3 mi/h^2$

To reach a speed of 183.58mi/h with an acceleration of $54\times 10^3 mi/h^2$

Using equation of motion

v=u+at

$183.58=0+(54\times 10^3)t$

$t=\frac{183.58}{54\times 10^3}$

t=0.00339 hours

t=12.23 s reach maximum speed

To complete course it takes

$s=ut+\frac{1}{2}at^2$

$5=0+\frac{1}{2}\times 54\times 10^3 \times t^2$

t=0.01360 hour

or $t=48.98\approx 49 s$
