Answer:

Step-by-step explanation:

Given that a box has cards numbered 1 ,2,3

Also a bag has three balls labelled A, B and C

Sample space = {(1,A)(1,B)(1,C) (2,A)(2,B)(2,C)} n(S) = 9

Mary will randomly pick up a card from the 3 cards and also pick up a ball from the bag of 3 balls.

The sample space contains the combination of letter on the card and number on the ball.

Event that the number chosen is 1 is

{(1,A)(1,B)(1,C)}: n(event of choosing 1)=3

A four foot tall girl cast a shadow of 6 feet. A shade tree cast a shadow of 24feet. What is the height of the tree?

aleksandr82 [10.1K]

The answer is 16.
the girls shadow is 6 feet, and the trees is 24. you get to 24 by multiplying by 4. so do the same thing for the height. if the girls height is 4, multiply by 4 to get to the trees height. 4x4 is 16.

Can somebody please help???

Darnel needs to spend three days making jam if he wants to jar 15 liters.

Step-by-step explanation:

If you are to assume the relationship is proportional then if he makes 10 liters in 2 days you divide 10 by 2 and you get 5. This means he makes 5 liters a day. Then you add 5 to 10 and you get 15 which means you are adding another day(5) So he needs to work an extra day which would give you three dyas total. Hope this helped!

(PLEASE ANSWER: TIMED)The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I(dB)=1

Mrac [35]

For this case we have the following equation:
$l(dB) = 10log( \frac{l}{lo} )$
We must replace the following value in the equation:
$l = 10^8lo$
Substituting we have:
$l(dB) = 10log( \frac{10^8lo}{lo} )$
Simplifying the given expression we have:
$l(dB) = 10log(10^8)$
Then, using logarithm properties in base 10, we can rewrite the expression:
$l(dB) = 10(8)$
Finally, making the product, the result is:
$l(dB) = 80$
Answer:
$l(dB) = 80$
