What is the percent decrease from 60 to 39?
IrinaK [193]
X - the percent decrease

60-60x=39 \ \ \ |-60 \\
-60x=-21 \ \ \ |\div (-60) \\
x=\frac{-21}{-60} \\ \Downarrow \\ x=\frac{-21}{-60}=\frac{-21 \div (-3)}{-60 \div (-3)}=\frac{7}{20}=\frac{7 \times 5}{20 \times 5}=\frac{35}{100}=35\%

It's a 35% decrease.

Caitlin says the difference in their ages is 24 years. In two or more complete sentences, explain whether or not Caitlin is corr
Paraphin [41]

~Hello There!~

\frac{m}{s} =\frac{2}{5}

Rearrange for s

s = \frac{5m}{2}

After 8 years, the new equation would be:

\frac{m+8}{s+8} =\frac{1}{2}

Cross multiply

2m+16 = s+8

Subtract 8

2m+8=s

Substitute old equation

2m+8 = \frac{5m}{2}

Solve to get m as 16.

s = 40.

Their current ages are 16 and 40 and the different is 24 years. Therefore, Caitlin is correct.

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^

In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lif
dexar [7]

Answer:

1.8m^2 approx

Step-by-step explanation:

Given data

P1= 1400N

A1=0.5m^2

P2=5000 N

A2=??

Let us apply the formula to calculate the Area A2

P1/A1= P2/A2

substitute

1400/0.5= 5000/A2

cross multiply

1400*A2= 5000*0.5

1400*A2= 2500

A2= 2500/1400

A2= 1.78

Hence the Area is 1.8m^2 approx
