The possible way to draw 5 cards hand from set of hearts-only deck is 15,4440 .
What is permutation?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol [tex]P_{r} ^{n}[/tex] is used to denote the number of permutations of n distinct objects, taken r at a time.
Formula of permutation
[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]
According to the question
Remove all of the hearts from a normal deck of cards.
i.e,
Total normal deck of cards = 52
On Removing hearts cards(n) = 13
Now, with this new hearts-only deck, how many possible five-card hands can you draw .
Card to draw (r)= 5
Applying formula of permutation
[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]
n = 13
r = 5
Substituting the values
[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13!)}{(13-5)!}[/tex]
[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13*12*11*10*9*8!)}{(8)!}[/tex]
[tex]P_{r} ^{n}[/tex] = 15,4440
Hence, the possible way to draw 5 cards hand from set of hearts-only deck is 15,4440 .

If a roof has a pitch of 5 to 11, how high will the roof rise over a 33-foot run?
Answer:
55-11=44 and 44-11=33 so 33 it is
Step-by-step explanation:
Well, 5 to 11 is just saying 5:11 just in a different way. This (:) means (to) also. So how you get the roof to a 33 foot run is to change the 5 into a 3 and the you leave the 11 alone and then you 33 -foot run. Well I really don't really know if that is ther correct anser but if it isn't then read someone's other answer because I don't really know what kind of math this is and I really need to know what grade it is and then I will look it up on the internet.

(6,5) and (3,5)?
Answer:
y = 5
Step-by-step explanation:
y = mx + b
5 = 6m + b
5 = 3m + b
Take the first minus twice the second.
-5 = - b
b = 5
Substitute back to calculate m.
5 = 6m + 5
6m = 0
m = 0

Answer:
5.831
Step-by-step explanation:
Pythagoras says RS = √(5²+3²) = √34 ≈ 5.831
Answer:
RS ≈ 5.83 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here RS is the hypotenuse and the legs have measure 5 and 3, thus
RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )
RS = [tex]\sqrt{34}[/tex] ≈ 5.83 ( to 3 significant figures )

Emma spent $16.00 on her order at Panera Bread. In her state, there is a 10% tax on food. What was her total bill after sales tax?
i need this answered so don't screw around btw its worth a lot of points :D
Answer:
$17.60
Step-by-step explanation:
We know that Emma spent $16.00 on her food.
There is a 10% tax.
Therefore, the total bill will be the price without tax plus the tax.
The price without tax is $16.00.
Tax is 10%. So, the tax will be 10% of 16.
10% of 16 is the same as 0.1(16) or 1.6.
So, the tax is $1.60.
Therefore, the total bill is:
$16.00+$1.60=$17.60.
Emma’s total bill comes to $17.60

A personal-size pizza has the radius shown in the diagram. Will the pizza fit on a plate with a radius of 10−−−√ inches or a radius of 12−−−√ inches. What is the approximate value of each radius?
9514 1404 393
Answer:
fits on a plate with radius √12√10 ≈ 3.16; √12 ≈ 3.46Step-by-step explanation:
A calculator can tell you the values of the square roots:
√10 ≈ 3.16
√12 ≈ 3.46
The radius of the pizza is larger than √10, so will not fit on that plate. It is less than √12, so will fit on a plate with radius √12.

At Middle school ,60% of the 800 students participate in music. How many students participate in music.???
Answer:
480
Step-by-step explanation:
800=100% value
x-60%
800/x = 100%/60%
now solve for x
(800/x)*x=(100/60)*x ( multiply both sides of the equation by x )
800=1.66666666667*x ( then we divide both sides of the equation by 1.66666666667 to get x )
480 = x
x= 480
so 60% of 800 is 480

A loan of $12,000 is made at 5.25% interest, compounded annually. After how many years will the amount due reach $22,000 or more?
Answer:
About 16 years
Step-by-step explanation:
First we need to figure out 5.25% of 12000
5.25 x 0.12000 = 0.63
Then we move the decimal
630
Then we need to figure out how many years it will take to reach $22000
Since we already owe $12000, we can just divide using $10000 because 10000 + 12000 = 22000
10000/630 = 15.87
Which is about 16 years

Primo car rental agency charges $50 per day plus $0.30 per mile. Ultimo car rental agency charges $20 per day plus $0.70 per mile. Find the daily mileage for
which the Ultimo charge is twice the Primo charge.
What is the mileage?
Answer:
cdcdc
Step-by-step explanation:
Answer:
Let's assume m represents the mileage of the car.
Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.
So, the total charge for this agency = 33 + 0.20m.
Similarly total charge of the ultimo car = 17 + 0.85m.
Now we need to find the daily mileage for which the ultimo charge is four times the primo charge. So, we can set up an equation as follows:
17 + 0.85m = 4 *( 33 + 0.20m )
17 + 0.85m = 132 + 0.80m By distribution property.
17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.
17 + 0.05m = 132
17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.
0.05m = 115
Divide each by 0.05.
So, m = 2300
Hence, the daily mileage is 2300 miles.
