The ratio of three numbers is 1.4.2 The sum of the numbers is 35. What are the three numbers?
Answer:
5.20.10
Step-by-step explanation:
The current Powerball jackpot is estimated to be $193 million. The Powerball lottery is decided every Wednesday and Saturday night by drawing five white balls out of a drum with 69 balls and one red ball out of a drum with 26 red balls. The Powerball jackpot is won by matching all five white balls in any order and the red Powerball. Each ticket costs $2. A ticket is defined as a set of five white and 1 red number.
Answer:
"2.660503478" would be the right answers to the key statement.
Step-by-step explanation:
Drawing 5 balls out of 69 can be done in ([tex]\frac{69}{5}[/tex])
= [tex]\frac{69\times 68\times 67\times 66\times 65}{5!}[/tex]
Drawing 1 ball out of 26 red balls can be done in ([tex]\frac{26}{1}[/tex])
= [tex]26[/tex]
Then the chance of drawing 5 out of 69 balls including 1 out of 26 red balls and then both matching the jackpot
= [tex]\frac{1}{11238513\times 26}[/tex]
= [tex]\frac{1}{292201338}[/tex]
Since the sum of the jackpot is $193-106 and then one ticket costs $2, the estimated value of buying one ticket again for jackpot is $2.
= [tex]\frac{1}{292201338}\times 193\times 10^6+\frac{292201338-1}{292201338}\times 2[/tex]
= [tex]2.660503478[/tex]
What is the equation written in vertex form of a parabola
with a vertex of (9, -1) that passes through (7, 7)?
Answer:
y = 2(x - 9)² - 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (9, - 1 ) , thus
y = a(x - 9)² - 1
To find a substitute (7, 7 ) into the equation
7 = a(7 - 9)² - 1 ( add 1 to both sides )
8 = 4a ( divide both sides by 4 )
2 = a , then
y = 2(x - 9)² - 1
Given: angle 1 and angle 2 form a linear pair,
Proven: angle 2 and angle 3 are supplementary
Answer:
Look at the proof down
Step-by-step explanation:
The given is;
→ ∠1 and ∠2 form a linear pair
→ ∠1 ≅ ∠3
We want to prove;
→ ∠2 and ∠3 are supplementary
We will write the proof in like a table
1. ∠1 and ∠2 formed a linear pair ⇒ 1. Given
2. m∠1 + m∠2 = 180° ⇒ 2. Sum of angles on a straight line
3. ∠1 and ∠2 are supplementary angles ⇒ 3. Supplementary angles add up to 180°
4. ∠1 ≅ ∠3 ⇒ 4. Given
5. m∠2 + m∠3 = 180° ⇒ 5. Substitution method
6. ∠3 is a supplement of ∠2 ⇒ 6. Supplement of equal angles
7. ∠2 and ∠3 are supplementary ⇒ 7. Proved

a cars tire pressure decreased by 0.098 of its original pressure write 0.098 as a percent
find all missing variables and measures of each angle
Answer:
y = 21
x = 48
Step-by-step explanation:
for y:
5y - 17 + 2y + 50 = 180
add like terms
7y + 33 = 180
subtract 33 from 180
7y = 147
divide 7 from 147
y = 21
for x:
x + 44 + 7x -248
add like terms
8x - 204 = 180
add 204 to 180
8x = 384
divide 8 from 384
x = 48
now plug it in to find angle measurements:
for y:
5 (21) - 17 = 88°
7 (48) - 248 = 88°
for x:
2 (21) + 50 = 92°
48 + 44 = 92°

Madison Finance has a total of $22 million earmarked for homeowner loans and auto loans, where x is homeowner loans in millions of dollars and y is auto loans in millions of dollars. On the average, homeowner loans have a 8% annual rate of return, whereas auto loans yield a 13% annual rate of return. Management has also stipulated that the total amount of homeowner loans should be greater than or equal to 4 times the total amount of automobile loans. Determine the total amount of loans of each type Madison should extend to each category to maximize its returns P in millions of dollars.Maxmize P=total loansdistributtion of loans
Answer:
Maximum returns = $1,980,000
x = Homeowner loans = $17,600,000
y = Auto loans = $4,400,000
Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000
Step-by-step explanation:
From the question we are told that:
Madison Finance has a total of $22 million earmarked for homeowner loans and auto loans, where x is homeowner loans in millions of dollars and y is auto loans in millions of dollars.
On the average, homeowner loans have a 8% annual rate of return, whereas auto loans yield a 13% annual rate of return.
We have the equation:
Maximum Return = 8% × x + 13% × y
= 0.08x + 0.13y
We are told in the question that
Management has also stipulated that the total amount of homeowner loans should be greater than or equal to 4 times the total amount of automobile loans.
Hence,
x ≥ 4y
So:
x + y = $22,000,000
4y + y = $22,000,000
5y = $22,000,000
y = $22,000,000/5
y = 4,400,000
x = 4y
x = 4(4,400,000)
x = 17,600,000
Maximum Return = 0.08x + 0.13y
= 0.08 × 17,600,000 + 0.13 × 4,400,000
= $1,980,000
Therefore, Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000

i dont have an explanation its just C
Answer:
the answer is 35.
Step-by-step explanation:
So first you look for 75 on the x-axis because this represents the number of people in attendance. 75 would be the line between 50 and 100. Then you need to follow the 75 line up until you see the point that the graphed line intersects the "75 line". When you drag you finger from that point over to the y-axis, you see the number of recyclables is about 35.

Answer:
x < 50
Step-by-step explanation:
No more means that it cannot equal 50. Therefore we can remove the 1st two options.
We now have the 3rd option and 4th option to choose from.
The 4th option is incorrect because the inequality is saying that a number is greater than 50.
∴ x < 50 is our answer.
