Biff is 25 years older than Hannah today. Four years from now,Biff will be 6 times as old as Hannah will be. How old is Hannah t

gavmur [86]

Hannah is 1 year old today.

Step-by-step explanation:

Let,

Hannah = x

Biff = y

According to given statement;

y = x+25 Eqn 1

In four years;

y+4 = 6(x+4) Eqn 2

Putting value of y from Eqn 1 in Eqn 2;

$(x+25)+4=6x+24\\x+25+4=6x+24\\x+29=6x+24\\29-24=6x-x\\5=5x\\5x=5$

Dividing both sides by 5

$\frac{5x}{5}=\frac{5}{5}\\x=1$

As x is age of Hannah, therefore,

Hannah is 1 year old today.

Anyone? Know how to do this?

ki77a [65]

Answer:

x = 4
length = 19 ft
width = 11 ft

Step-by-step explanation:

The area is given by the product of length and width.

A = LW

209 = (4x +3)(4x -5)

209 = 16x^2 -8x -15

224 = 16x^2 -8x

You could rearrange and use the quadratic formula at this point, but we elect to "complete the square".

14 = x^2 -(1/2)x

14 +1/16 = x^2 -1/2x +(1/4)^2 . . . . . add the square of half the x-coefficient

(x -0.25)^2 = 14.0625

x = 0.25 ± 3.75 . . . . . . take the square root; add 0.25

Only positive values of x are useful here, so we have

x = 4

Then the dimensions are ...

length = 4x +3 = 4(4) +3 = 19 . . . feet

width = 4x -5 = 16 -5 = 11 . . . feet

If StartFraction pi Over 2 EndFraction less than t less than pi , which of the following is true?

oksian1 [2.3K]

Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

$\frac{\pi }{2} < t$

if we apply the cosine function in the relation we get:

$cos\frac{\pi }{2}$

$-1$

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

$cotan\frac{\pi }{2}$

$0$

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0
