Answer:

22-18-25,

19-24-30,

7-24-25

Step-by-step explanation:

In a triangle with side lengths $a$ , $b$ , and $c$ , any two sides must have a sum larger than the third.

Using this rule, the possible side lengths out of these choices that could form a triangle are:

22-18-25,

19-24-30,

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?

Ghella [55]

Increased height:-

$\\ \sf\longmapsto 23\times 15\%$

$\\ \sf\longmapsto 23\times \dfrac{15}{100}$

$\\ \sf\longmapsto \dfrac{345}{100}$

$\\ \sf\longmapsto 3.45$

Now current height:-

$\\ \sf\longmapsto 23+3.45=26.45ft$

Solve for a: b − 2a = c

vlada-n [284]

Answer:

$a=-\frac{c-b}{2}$

Step-by-step explanation:

Solving for the variable $a$ , given that :

$b-2a=c$

We can first start start by subtracting $b$ from both sides of the equation:

$-2a=c-b$

Now, we can divide both sides of the equation by the coefficient of $a$ , which would be $-2$ :

$a=\frac{c}{-2}-\frac{b}{-2}$

Applying the fraction rule $\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}$ :

$a=\frac{c-b}{-2}$

Then, apply the fraction rule $\frac{a}{-b} =-\frac{a}{b}$

$a=-\frac{c-b}{2}$

The human population doubles approximately every 50 years if there were 2.5 million people in 1950 how many people are forecaste

Margarita [4]

The equation that would let us determine the number of people or population at a certain year is calculated through the equation,

A(t) = A(o)(2^(t - 1950)/50)

Substituting the known values,

A(t) = (2.5 million people)(2^(2100 - 1950)/50))

A(t) = 20 million

<em>Answer: 20 million people</em>
