Answer:
1 / 14608440
Step-by-step explanation:
Given the following :
Winner has to select the five correct numbers between 1 and 35
Then, a single correct number between 1 and 45
Step1:
Number of ways to select 5 corre t numbers between 1 and 35; selecting 5 things from a total of 35 = 35C5
nCr = n! ÷ (n-r)!r!
35C5 = 35! ÷ (35-5)!5!
35C5 = 35! ÷ (30)!5!
= (35 * 34 * 33 * 32 * 31) / (5 * 4 * 3 * 2 * 1) = 324632 ways
Then find number of ways of selecting 1 correct number between 1 and 45:
45C1
45C1 = 45! ÷ (45-1)!1!
45C1 = 45! ÷ (44)!1!
45C1 = 45 ÷ 1 = 45
35C5 * 45C1 = 324632 * 45 = 14608440
Therefore, probability of winning the jackpot :
Required outcome / Total possible outcomes
= 1 / 14608440
Prove the identity sin^2theta x csc^2 theta = sin^2 theta + cos^2 theta 20 points!!
Answer:
Step-by-step explanation:
sin² Θ csc² Θ =sin² Θ + cos² Θ
sin² Θ 1/sin² Θ = sin² Θ + cos² Θ

Miguel's basketball team is down seven points from their opponents. If they make a two-point field goal, how many more points do they need to tie the game? Justify your answer by writing a number sentence to represent this situation.
Answer: Answer is the steps
Step-by-step explanation:
If they are down by seven points then it means that they are losing by 7 points.And fortunately they made two-point field goal so they will now be down by 5 points. Which means that they need 5 more points to tie the game.
For example,
-7 represents the points that they are down by and they made 2 points so
-7 + 2 = -5 which means that they are now down by 5 points to make a tie game.
Answer:-7+2+5=0

Answer:
A.) As x increases, the rate of change of g exceeds the rate of change of f
Step-by-step explanation:
Let's take the options given and look at them to actually know which is true.
Option A
We notice that as x increase in value the rate of change of g starts exceeding the rate of change of f.
Then it's exceeds it from the value x = 5
Option B
At x= 4.39
F= 2616.689
G= 2606.657
They are different values
Option C
That's opposite of option A
But option A is true which signify option C to be false
Option D
Not true also.
We can see from x= 0 to 4 the rate of change of F exceeds that of G

A 108-inch is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece.
Long piece is 81 inches
====================================================
Explanation:
x = length of short piece
3x = length of the longer piece (3 times longer)
x+3x = 4x = total length
total length = 108
So 4x = 108 is the equation which solves to x = 27 after dividing both sides by 4.
The short piece is x = 27 inches and the long piece is 3*x = 3*27 = 81 inches. Adding the two pieces gives 27+81 = 108 which helps confirm the answer.
1. Tell whether the number 47 is prime
or
composite. Then write all the factors of the number.
2.Tell whether the number 81 is prime
or
composite. Then write all the factors of the number
Answer:47 is a prime and 81 is a composite
Step-by-step explanation:47={1,47}
81={1,3,9,18,27,81}
1. The number 47 is prime. The only factors are 1 and itself. We can check by dividing 47 over the list of primes smaller than 47. To be more efficient, we can stop once we reach sqrt(47) = 6.85. So we only need to check the primes {2, 3, 5} to show they are not factors of 47 to show that 47 is prime.
=====================================
2. The number 81 is composite. It is not prime because it has factors other than 1 and itself.
There are 5 factors and they are
1, 3, 9, 27, 81
Note how each factor listed is a power of 3 (1 = 3^0, 3 = 3^1, 9 = 3^2, 27 = 3^3, 81 = 3^4)
The prime factorization of 81 is
81 = 3*3*3*3 = 3^4

A. m = -43
B. m = -23
C. m = 23
D. m = 43
Answer:

Answer:
7/40 is the fraction filled with water
Step-by-step explanation:
Here we start by calculating the volume of the cylindrical tank.
Mathematically, that would be;
V = π * r^2 * h
From the question
r = 80 cm = 80/100 = 0.8 meters
h = 1.4 meters
π = 22/7
Plugging these values into the volume equation, we have;
V = 22/7 * 0.8 * 0.8 * 1.4 = 2.816 m^3
But mathematically;
1 m^3 = 1000 liters
So 2.816 m^3 = 2.816 * 1000 = 2816 liters
So the fraction filled with water will be;
492.8/2816 = 0.175 = 175/1000 = 7/40

hours studying in the morning and 3 3/4 hours
studying in the afternoon. How many hours
did Jacob spend studying that day?
Answer:
5 19/20 or 5.95
Step-by-step explanation:
You can add these numbers as decimal numbers or as mixed numbers.
Decimal
2.2 +3.75 = 5.95 . . . hours spent studying
Mixed Numbers
(2 1/5) +(3 3/4) = (2 4/20) +(3 15/20) = (2 +3) +(4/20 +15/20)

scott can deliver 10 pizzas per hour and kenneth can deliver 12 per hour how mnay hours will it take them to deliver 110 pixzas
Answer:
5 hours
Step-by-step explanation:
Scott's delivery rate = 10 pizzas per hour
Kenneth's delivery rate = 12 pizzas per hour
Combined delivery rate
= Scotts delivery rate + Kenneth's delivery rate
= 10 + 12
= 22 pizza's per hour (take reciprocal to find the rate in "hours per pizza")
= 1/22 hours per pizza
Given that they both deliver 110 pizzas combined, the will take
= 1/22 hours per pizza x 110 pizzas
= (1/22) x 110
= 5 hours

See below.
Step-by-step explanation:
Since the two triangles are similar, this means that their corresponding sides are proportional. In other words:
[tex]\frac{PQ}{XY}=\frac{QR}{YZ}=\frac{RP}{ZX}[/tex]
Part A:
We already know PQ, RP, XY, and YZ.
To find XZ, we can use the first and third proportions:
[tex]\frac{PQ}{XY} =\frac{RP}{ZX} \\=\frac{7.2}{18}=\frac{6.5}{ZX}[/tex]
Cross multiply:
[tex]117=7.2(ZX)\\ZX \text{ or } XZ = 16.25[/tex]
Part B:
The same thing as Part A, but with the first and second proportions:
[tex]\frac{PQ}{XY}=\frac{QR}{YZ}\\\frac{7.2}{18}=\frac{QR}{7}\\50.4=18(QR)\\QR=2.8[/tex]
how do you solve this problem ? 4(-3x+1)-3x=71
Answer:
x = -67/15 = -4-46667
Step-by-step explanation:
4(-3x+1) - 3x = 71
4*-3x + 4*1 - 3x = 71
-12x + 4 - 3x = 71
-15x = 71-4
-15x = 67
x = 67/-15
x = -4.46667
check:
4(-3*-4.46667 + 1) - 3*-4.4666= 71
4(13.4+1) + 13.4 = 71
4*14.4 + 13.4 = 71

dlklf,vkvkdcñclcdliffoIf the lengths of the legs of a right triangle are 4 and 8, what is the length of the hypotenuse?
Answer:
8.94~9.0
Step-by-step explanation:
If A squared plus B squared equals C squared. Then you can used this formula and find that 4 squared plus 8 squared equals 80. then square root 80 to find 8.94 or rounded to 9. This would equal C or the hypotenuse. Hope this helps!
The required length of the hypotenuse of the triangle is 16√5.
Given that,
If the lengths of the legs of a right triangle are 4 and 8, what is the length of the hypotenuse is to be determined.
In a right-angled triangle, its side, such as hypotenuse, perpendicular, and the base is Pythagorean triplets.
Here,
Applying the Pythagorean theorem,
Hypotenuse² = perpendicula² + base²
Hypotenuse² = 8² + 4²
Hypotenuse² = 64 + 16
Hypotenuse² = 80
Hypotenuse = √80
Hypotenuse = 16√5
Thus, the required length of the hypotenuse of the triangle is 16√5.

Therefore, 0.015476hrs to cover 1 mile distance.
Hope it helps...
Answer:
64.6153846 miles/hour
0.0154761905 hours/mile
Step-by-step explanation:
If we want to find the miles driven in one hour, we must divide the total miles by the total hours.
miles / hours
We know that 420 miles were driven in 6.5 hours
420 miles/ 6.5 hours
Divide 420 by 6.5
420/6.5=64.6153846
64.6153846 miles/hour
In one hour, 64.6153846 miles are driven.
If we want to find the time to drive one mile, divide the time (hours) by the miles.
hours / miles
We know that 420 miles were driven in 6.5 hours.
6.5 hours/420 miles
Divide 6.5 by 420
6.5/420=0.0154761905
0.0154761905 hours/ mile
It will take 0.0154761905 of an hour to drive one mile.
