If 60% of a number is 144 what is the number?
Sonja [21]

Answer:

240

Step-by-step explanation:

So 60/100 x (n) = 144

We should be able to multiple both sides by 100, and divide each side by 60 to get our answer.

n = 144 x (100/60) which then equals 240.

Dr. Anderson found that 18 out of 30 children in the village tested positive for chicken pox. At this rate, how many would test
Artist 52 [7]

Answer:number of children negative for chicken pox=28

Step-by-step explanation:

Number of  children positive for chicken pox =18 out of 30

Therefore number  of children negative for chicken pox is 12 out of 30 ie ( 30-18)

Such that the ratio of positive tested chicken pox children to negative tested chicken pox children =18:12

Therefore  total ratio =18 +12=30

Suppose there are 70 children,then number of children negative for chicken pox =

12/30 x 70  =28

6(4.5y – 12) = 9 can someone help me anwser this please
quester [9]

Answer: y=3

Step-by-step explanation: 6(4.5y−12)=9

Step 1: Simplify both sides of the equation.

6(4.5y−12)=9

(6)(4.5y)+(6)(−12)=9(Distribute)

27y+−72=9

27y−72=9

Step 2: Add 72 to both sides.

27y−72+72=9+72

27y=81

Step 3: Divide both sides by 27.

27y/27 =81/27

Ai Lun, a management trainee at a large New York based bank, is trying to estimate the real rate of return expected by investors
salantis [7]

Answer:

option B

Step-by-step explanation:

given,                                              

3-month T-bill currently yields  = 3%          

customer price have been rising = 2% rate

Ai Lun's estimate of the real rate = ?            

real rate return                                                  

                       = \dfrac{1 + risk\ free\ rate}{1 +inflation\ rate} - 1

                       = \dfrac{1 + 0.03}{1 +0.02} - 1

                       = \dfrac{1.03}{1 .02} - 1

                       = 1.0098 - 1

                       = 0.0098

                       = 0.98 % ≅ 1 %

hence, the correct answer is option B
