166 I guess you just subtract the numbers 297-131= Or there is something am I missing on here

♥ If you have 297 dogs but you lost 131, to solve, you will subtract.
This is because you are taking away.
⇒ 297-131=166
♥ Therefore you have 166 dogs left.

Let y=f(x)=(3x+7)/(x-2) <br> find a rule for f^-1

Murrr4er [49]

Answer:

$f^{-1}(x)=\frac{2x+7}{x-3}$ .

Step-by-step explanation:

The given function is $f(x)=\frac{3x+7}{x-2},\:x\ne2$ .

We want to find a rule for $f^{-1}(x)$ .

Let $y=\frac{3x+7}{x-2}$ .

Interchange x and y.

$x=\frac{3y+7}{y-2}$ .

Solve for y.

$x(y-2)=3y+7$ .

Expand

$xy-2x=3y+7$ .

Group y-terms

$xy-3y=7+2x$ .

Factor

$(x-3)y=7+2x$ .

$y=\frac{2x+7}{x-3}$ .

$\therefore f^{-1}(x)=\frac{2x+7}{x-3},\:x\ne3$ .

Two cubes have their surface areas in the ratio 1:4 , what is the ratio of their volumes ?

yKpoI14uk [10]

Answer:

1 : 8

Step-by-step explanation:

For similar figures with ratio of sides = a : b

Then ratio of areas = a² : b² and

ratio of volumes = a³ : b³

Given ratio of areas = 1 : 4

linear ratio = $\sqrt{1}$ : $\sqrt{4}$ = 1 : 2

ratio of volumes = 1³ : 2³ = 1 : 8

Answer:

100 children

150 adults

Step-by-step explanation:

c- children

a- adults

---------------

we get equations as per question:

1.5c+4a= 750
c+a= 250 ⇒ a= 250- c

1.5c +4(250-c)= 750 ⇒
1.5c- 4c+1000=750 ⇒
2.5 c= 250 ⇒
c= 100
a= 250-100 ⇒
a= 150

Children 100, adults 150
