What is the number of males in barangay 127 t years since 2000 when f(t) represents the number of females in barangay 127 t year

natta225 [31]

Answer:

$h(t) = g(t) - f(t)$

Step-by-step explanation:

Given

f(t) = Population of females

g(t) = Population of people

Required

Determine the population of males

Represent the required population with h(t)

With the assumption that, one can either be male or female (but not both), the relationship between f(t), g(t) ang h(t) is:

$g(t) = f(t) + h(t)$

i.e.

$People = Male + Female$

Make h(t) the subject in $g(t) = f(t) + h(t)$

$h(t) = g(t) - f(t)$

Answer:

The container can hold 18 gallons

Step-by-step explanation:

Assume the container can hold x gallons

∵ The container is $\frac{2}{3}$ full with water

∵ It can hold x gallons

→ Multiply $\frac{2}{3}$ by x to find the number of gallons in the container

∴ The number of gallons in the container = $\frac{2}{3}$ x

∵ 4 gallons of water pouring out

∵ It is $\frac{4}{9}$ full

→ Multiply $\frac{4}{9}$ by x to find the number of gallons left in it

∴ The number of gallons left in the container = $\frac{4}{9}$ x

→ The difference between the numbers of gallons is 4 gallons

∵ $\frac{2}{3}$ x - $\frac{4}{9}$ x = 4

→ Subtract the terms of the left side

∴ $\frac{2}{9}$ x = 4

→ Multiply both sides by 9

∴ 2x = 36

→ Divide both sides by 18

∴ x = 18

∵ x represents the full of the container

∴ The container can hold 18 gallons

ratelena [41]

Answer:

x = 3

Step-by-step explanation:

Use the Pythagorean theorem:

$x^2+x^2=(3\sqrt2)^2\qquad\text{use}\ (ab)^n=a^nb^n\\\\2x^2=3^2(\sqrt2)^2\qquad\text{use}\ (\sqrt{a})^2=a\\\\2x^2=(9)(2)\\\\2x^2=18\qquad\text{divide both sides by 2}\\\\x^2=9\to x=\sqrt9\\\\\boxed{x=3}$
