Answer:

5) y=5

6)x=7

7)a=18

Step-by-step explanation:

5) y= any number will work. don't add a variable like x

6)x= any number will work. don't add a variable

My work for 7 is in the picture. If you'd like me to explain more for 7 lmk :)

There are 52 cards in a standard deck: 13 hearts, 13 clubs, 13 diamonds , and 13 spades. Timothy draws four cards at random from

siniylev [52]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

Total number of cards in a standard deck = 52

Number of hearts in the deck = 13

Number of clubs in the deck = 13

Number of diamonds in the deck = 13

Number of spades in the deck = 13

Four cards are drawn at random by Timothy.

These four cards are drawn from each one of the suits.

And the cards are not replaced.

Therefore, now cards remaining in each suit:

Remaining number of hearts in the deck = 12

Remaining number of clubs in the deck = 12

Remaining number of diamonds in the deck = 12

Remaining number of spades in the deck = 12

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, number of favorable cases are 12 (i.e. number of hearts)

Total number of cases = 12 $\times$ 4 = 48

Therefore, the required probability is:

$\dfrac{12}{48} = \bold{\dfrac{1}4}$

How many years will it take for an initial investment of $20,000 to grow to $30,000? Assume a rate of interest of 6% compounded

Genrish500 [490]

F = Pe^(rt)

F is the final amount

P is the principal

r is the interest rate

t is the time in years

30000=20000 e^(.06t)

divide by 20000

3/2 = e ^ .06t

take the ln on each side

ln(3/2) = .06t

divide by .06

ln(3/2)/.06 =t

t=6.75775 years

A rectangular parking lot at the megamall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?

Greetings!

"<span>A rectangular parking lot at the mega-mall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?"...

This question is essentially asking to solve for the perimeter. The formula for the perimeter of a rectangle is:
</span> $2(l+w)$

Input the information we already know:
$2(7/10+1/4)$
Find A common denominator.
$2(14/20+5/20)$
Simplify.
$2(19/20)$
$2/1(19/20)$
$38/20$
Reduce to Lowest Terms.
$=19/10$
or
$=1 9/10$

1 9/10 miles of fencing will be required to enclose the entire lot.

Hope this helps.

Answer:

x = 6, y = 0, m = -1
y = mx + b
0 = -1(6) + b
0 = -6 + b
6 = b
y = -1x + (6)
