A zoo has 14 monkeys and 18 chimpanzees.

To write the ratio of numbers x and y we use three ways given below

1. x to y

2. x : y

3. \frac{x}{y}

Now write the ratio in three ways comparing 14 monkeys and 18 chimpanzees.

Let x be the number of monkeys

y be the number of chimpanzees

So ratio becomes

14 to 18

14 : 18

\frac{14}{18}

I really need someone to explain to me on how to solve these!! :(
HACTEHA [7]

Answer:

3.7%

Step-by-step explanation:

(p)principal=$3400

(t)time=9months=9÷12year=3÷4year

(i)interest=$94.50

(r)rate=?

we have

r%=i/(pt)

r%=94.50÷(3400×3÷4)

r÷100=94.50÷2550

r=0.37×100

r=3.7

required rate is 3/7%

2v+18=16-4(v+7) how does one do this
Pani-rosa [81]

v = - 5

distribute right side of equation and simplify

2v + 18 = 16 - 4v - 28

2v + 18 = - 12 - 4v ( add 4v to both sides )

6v + 18 = - 12 ( subtract 18 from both sides )

6v = - 30 ( divide both sides by 6 )

v = \frac{-30}{6} = - 5

Prove that (x^5)-(x^2)+2x +3=0 has at least one real root.
lutik1710 [3]
The first one is of order 5, so it has either 1, 3 or 5 real roots (unless any coefficent was complex). Proof complete :)
The other one, if it has a solution, it must be in [-1;1]. Because it only gives positive results the solution is further restricted to [0;1]. Because the cosine function is continuous and strictly decreasing on this interval, the difference of x and it's cosine will shrink up to some point within the interval where it gets to 0 (the solution) and then flips sign (the cosine gets less than the number), further decreasing until the end of the interval.
