Answer:10%= 310

5%= 155

15%=465

Step-by-step explanation: Solution for what is 15% of 3100

3100/x=100/15

(3100/x)*x=(100/15)*x       - we multiply both sides of the equation by x

3100=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x

3100/6.66666666667=x

465=x

x=465

If 3 to the power of x+1 = 81 and 81 to the power of x-y = 3 then what is the value of x and y?
fgiga [73]
From 1st condition:

3^(x+1)=81
Take log on both sides,
➡ log [3^(x+1)]=log81
Use the property: log(x^a)=a logx
➡ (x+1) log 3=log(3⁴)
➡ (x+1) log 3=4×log 3
➡ (x+1)=4 (log 3 /log 3)
➡ x+1=4
➡ x=3➡↪➡↪ ANS

From 2nd condition, (Same process are repeated)

81^(x-y)=3
➡ 3^4(x-y)=3
➡ log [3^4(3-y)]=log 3
➡ 4(3-y) log 3=log 3
➡ (3-y)=(log 3)/(4log 3)
➡ 3-y=(1/4)
➡ y=11/4 ➡↪➡↪ ANS

galina1969 [7]

Answer:

28

Step-by-step explanation:

Plug in the corresponding numbers to the corresponding variables. Note that:

m = 7

r = 8

t = 2

mr/t = (7 * 8)/2

(7 * (8/2)) = 7 * 4 = 28

28 is your answer.
