An chocolate cake was taken out of the oven and placed on the counter to cool. The initial temperature of the chocolate cake was 789.2 degrees Fahrenheit. The temperature dropped 4.1 degrees Fahrenheit each minute that it sat on the counter. About how many minutes, m, will it take for the temperature of the chocolate cake to reach 160 degrees Fahrenheit? (Write answer as decimal with no units) (Round answer off to tenths place)( Round off one place behind decimal point)

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
