HELP QUICK!!!

svetlana [45]

The first step is to find the distance from the given point to each of the two foci as follows:
Distance D1:
(D1)^2 = (9-1)^2 + (0-6)^2 = 100
D1 = 10
Distance D2:
(D2)^2 = (11-1)^2 + (6-6)^2 = 100
D2 = 10

The constant sum is the summation of the two distances as follows:
constant sum = D1 + D2 = 10 + 10 = 20

The correct choice is:
a) 20

Lilly has $35,she went to the store and spender 10% of it,how much money she has left?

kirill115 [55]

Hi there! Lily has $31.50 left.

To find our answer we first need to know the amount of money Lily spend.
$10\% \times 35 = 0.1 \times 35 = 3.50$

Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.

$35 - 3.50 = 31.50$
Hence, Lily has $31.50 left.

Please I need some help

For the first question, all you need to know is that the (amount you want) divided by (the amount of cards total) is the probability of getting the amount you want at random. for example, if there are 3 red marbles in a bag of ten marbles, you divide 3 by 10 (0.30) the probability of picking up a red marble is 30%. try adding up how many cards you want to pick up by the number of cards total.
