The odds against drawing a 6, 7, 8 or 9 in a deck of 52 cards are given as follows:
2.25 : 1.
What is a probability and what is an odd?A probability is given by the number of desired outcomes divided by the number of total outcomes.An odd is the number of desired outcomes divided by the number of non-desired outcomes.Each number in a set of 52 cards has 4 cards, hence the number of cards with 6, 7, 8 or 9 is given as follows:
4 x 4 = 16.
Then the number of cards without these numbers is given as follows:
52 - 16 = 36.
Meaning that the odds against drawing these numbers is given as follows:
36 : 16 = 2.25 : 1.

h(x)=6/(x-3), find h(5)
h(5) means the value of h(x) at x = 5. So what we have to do is to substitute x = 5 in the function.
We are given the function h(x) below:
[tex] \large{h(x) = \frac{6}{x - 3} }[/tex]
Substitute x = 5 in the equation.
[tex] \large{h(5) = \frac{6}{5 - 3} \longrightarrow \frac{6}{2} }[/tex]
Simplify in the simplest form.
[tex] \large{h(5) = \frac{3}{1} \longrightarrow 3}[/tex]
Thus h(5) is 3.
Answer
h(5) = 3Hope this helps! Let me know if you have any doubts.
Find the largest possible rectangular area you can enclose, assuming you have 128 meters of fencing. What is the (geometric) significance of the dimensions of this largest possible enclosure?
Answer:
Step-by-step explanation:
let the length=x
width=y
P=2(x+y)=128
x+y=128/2=64
y=64-x
area A=xy=x(64-x)=64x-x²
[tex]\frac{dA}{dx} =64-2x\\\\\frac{dA}{dx} =0,gives~64-2x=0,x=32\\\frac{d^2A}{dx^2} =-2<0 ,at ~x=32[/tex]
so A or area is maximum if x=32
y=64-32=32
or it is a square of edge=32 meters.

Answer:
22
Step-by-step explanation:
Put -3 where x is and do the arithmetic.
f(-3) = 3(-3)² -2(-3) -11 = 27 +6 -11
f(-3) = 22

Additional comment
Sometimes evaluation is easier if you rewrite the polynomial in Horner form:
f(x) = (3x -2)x -11
f(-3) = (3(-3) -2)(-3) -11 = -11(-3) -11 = 33 -11 = 22
Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)f(x)=36x−2x^2

Step-by-step explanation:
Given
[tex]f(x) =36x -2x^2[/tex]
Required
Determine the critical numbers
First, we differentiate f(x)
[tex]f'(x) = 36 - 4x[/tex]
Set to 0 and solve for x
[tex]36 -4x = 0[/tex]
Make 4x the subject
[tex]4x = 36[/tex]
Solve for x

In a right triangle, angle C measures 40°. The hypotenuse of the triangle is 10 inches long. What is the approximate length of the side adjacent to angle C?
6.4 inches
7.7 inches
8.4 inches
13.1 inches
Answer:
The cosine function is: adjacent/hypotenuse = cos (40). We know the hypotenuse length is 10, so the equation is now adjacent/10 = cos (40). Solving for adjacent length we get 7.7 inches.
Answer:
the answer is B: 7.7 inches

Raquel needs to rent a car while on vacation. The rental company charges $19.95, plus 19 cents for each mile driven. If Raquel only has $40 to spend on the car rental, what is the maximum number of miles she can drive?
__________ miles
Answer:
105
Step-by-step explanation:
$40 - $19.95 = $20.05
$20.05 divided by 0.19 (19¢) = 105.526316
Answer:
105 miles
Step-by-step explanation:
40-19.95= 20.05

please help lollllllllllllllllllll
Answer:
A. 12.21
Step-by-step explanation:
Define and explain:
This a right triangle, so the Pythagorean Theorem applies. The Pythagorean Theorem states that the sum of the squared legs is equal to the squared hypotenuse.
The legs of a triangle are the sides that form the right angle.
The hypotenuse is the longest side.
Formula:
[tex]a^2+b^2=c^2[/tex]
[tex]a,b-legs[/tex]
[tex]c-legs[/tex]
Here, I am solving for the hypotenuse.
[tex]7^2+10^2=c^2[/tex]
[tex]49+100=c^2[/tex]
[tex]149=c^2[/tex]
The last step is to find the square root of 149.
The square root of 149 is irrational, of course, so I must round the square root to the nearest hundredth.
[tex]12.2065556157[/tex] ≈ [tex]12.21.[/tex]
[tex]12.21=c[/tex]
Conclude:
I, therefore, believe the length of the hypotenuse is 12.21.

Will Mark Brainlest help step by step. (The ratio of two men present age is 3:4 and this will be 7:9 after 4 years what are their present age)
Answer:
24 and 32
Step-by-step explanation:
Let their present ages be x and y
Therefore, x
[tex] \frac{x}{y} = \frac{3}{4} [/tex]
we have 4x = 3y
4x - 3y = 0......................(I)
After four years,
[tex] \frac{x + 4}{y + 4} = \frac{7}{9} [/tex]
we have, 9(x + 4) = 7(y + 4)
9x + 36 = 7y + 28
9x - 7y = -8 ........................(ii)
Solving (I) and (ii) simultaneously
4x - 3y = 0
9x - 7y = -8
multiply eqn I by 9 and equation (ii) by 4 and subtract result
36x - 27y = 0...............(iii)
36x - 28y = -32...........(iv)
subtracting (iv) from (iii) we have,
y = 32
substituting y back in equation (I)
4x - 3y = 0
4x -3(32) = 0
4x - 96 = 0
4x = 96
x = 24
Their ages are 24 and 32
To rent a car, Cesar must pay $15 a day plus 5 cents for every mile he drives. In dollars, what is his final bill if he rents a car for 3 days and drives a total of 50 miles?
Answer:
$70
Step-by-step explanation:
What we know:
⇒ He must pay 15 dollars a day
⇒ He needs to pay an additional 5 cent for every mile he drives
⇒ He drives 50 miles for 3 days
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Since he pays $15 a day and he is driving this car for 3 days, we have to multiply 15 by 3.
15*3=45
He drove 50 miles and each mile is 5 cents so we have to multiply those as well.
50*.5=25
Now we add both the sums togather~
25+45= $70

Step-by-step explanation:
[tex]sin(A+B ) = 1\\\\\ \ \ (A + B) \ = \ \ sin^{-1} 1\\\\A + B = 90^\circ --(1)\\\\ \ tan (A - B) = \frac{1}{\sqrt{3}}\\\\(A-B) = tan^{-1}\frac{1}{\sqrt3}}\\\\A - B = 30^\circ --(2)\\\\ (1) + (2) => 2A = 120^\circ\\[/tex]
[tex]A = 60^\circ[/tex]

If the pool is to be 24 ft on each side, what is the length of one side of the hot tub?
Answer:
the side length of the hot tub = 4.8ft
Step-by-step explanation:
Scale Factor = 5
Also,
B'C' = 24 feet
Since both are squares so both have all sides equal.
Square A'B'C'D' is dilated by a scale factor of 5
So,
AB = BC = CD = DA = 24/5 = 4.8 ft.
i hope this helps you
The length of the one side of the hot tub is 4.8 ft.
What is Scale Factor?
The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
Here, Richardo wants to build a square pool of the hot tub using a scale factor of 5.
If the each side of the pool is 24 ft.
The length of one side of hot tub = 24/5 = 4.8 ft.
Thus, the length of the one side of the hot tub is 4.8 ft.

Xavier, Yi, and Zazoo decide to share their lottery winnings of £11000 such that Yi has three times as much as Zazoo and Xavier has half of Yi’s winnings. How much should each receive?
Answer:
2000 ; 6000 ; 3000
Step-by-step explanation:
Given:
Total lottery winning = £11,000
Let :
Zazoo's share = x
Yi's share = 3x
Xavier's share = 3/2x
Total share = (x + 3x + 3/2x) = 5.5x
Total winning / total share
x = £11000 / 5.5
= 2000
Zazoo's share = £2000
Yi's share (2000 * 3) = £6000
Xavier's share = 3/2 * 2000 = £3000
