Answer:

41.07

Step-by-step explanation:

1) lets use the formula, (%/100)=is/of

so:

is=23

of=x

%=56

\frac{56}{100} =\frac{23}{x}

cross multiply

56x=2300

x=41.07

so the proportions I would use are:

56/100 and 23/x

A pet store sold 36 Siamese cats. If the ratio of Siamese cats to house cats sold was 4:9, what is the combined amount of cats s
Dafna11 [192]

 The combined amount of cats sold is 117.

Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.

The ratio of  Siamese cats to house cats = 4 : 9

Number of Siamese cats = 36

Number of combined cats = c

This equation can be formed using the above information:

4/13 x c = 36

4c = 468

c = 468 / 4

c = 117

ANSWER ASAP PLEASE FOR BRAINLIEST
Lelechka [254]

Answer:

<h2><em><u>11.2 - B to C</u></em></h2><h2><em><u>12 - B to A</u></em></h2><h2><em><u>8.8 - A to C</u></em></h2>

You have to multiply all the sides by 4.

B to C = 2.8*4

2.8 * 4 = 11.2

B to A = 3*4

3*4 = 12

A to C = 2.2*4

2.2*4 = 8.8

Hope this helped!

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's  Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20
