before area, we need to calculate length & width

let, width = x

length = 3x

so, 64 = 2(3x+x)

8x = 64

x = 8 (width)

3x = 24 (length)

So, area would be: 24 * 8 = 192 cm²

How do you solve 4y-8x=12
77julia77 [94]
You have to think about what y and x can be equal to for you to get 12. (Hint: y is going to be a bigger number than x)


Ex: 3y-5x=5

Think: 3 x 10(y) - 5 x 5(x)= 5
So, y would be 10 and x would be 5.

Arisa [49]

Answer:

The probability that a person is younger than 50 given that she uses onling banking is 1.5%

Step-by-step explanation:

The survey indicated that 50% of adults conducts their banking online.

P(online banking customers) =1/2

Of the total number of customer that bank online, the survey stated that 20% of them are younger than 50 years.

P(customers younger than 50 yrs) =1/5

Out of the 20% than are younger than 50, we were told that 15% of them conduct online banking.

P(younger than 50 online banking customer) =3/20

Therefore the the probability that a = person is younger than 50 given that she uses online banking is  P = 3/20*1/5*1/2 =17==3/200 = 0.015 =1.5%

The probability that she is younger than 50 does not increase or decrease with additional information, it only makes it clearer.

If v is cut in half, then w is multiplied by (1/(1/2))^2 = 4.

When v=3, w=12.

Kirk used 10.2 centimeters of tape to wrap 3 presents. How many presents did Kirk wrap if he used 23.8 centimeters of tape?
insens350 [35]

Answer:

Kirk wrapped 7 presents with those 23.8 cm of tape.

Step-by-step explanation:

Figure out the unit rate:

10.2 cm tape

-------------------

  3 presents

or

   3 presents

-----------------------

  10.2 cm tape

Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:

(3 presents)(23.8 cm tape

Kirk wrapped 7 presents with those 23.8 cm of tape.
