Answer 2

The simplified expression of 4 +9 "/" 3 "/" 2 x 3 + (3 + 1) x 4 is 17, following the order of operations or PEMDAS.

To simplify the given expression, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

The original expression is 4 +9 / 3 / 2 x 3 + (3 + 1) x 4. First, address operations inside parentheses: (3+1) equals 4. The expression becomes 4 +9 / 3 / 2 x 3 + 4 x 4.

Next, handle the multiplication and division from left to right: 9 / 3 equals 3, and 2 x 3 equals 6. Then, 4 x 4 equals 16. This turns our expression into 4 + 3 - 6 + 16.

Finally, perform addition and subtraction from left to right: 4 + 3 equals 7, 7 - 6 equals 1, and 1 + 16 equals 17. Therefore, the simplified expression is 17.

in which number does the 6 have a value that is one tenth the value of the 6 in 34, 761

Answers

Final answer:

The 6 in 600 has a value one tenth the value of the 6 in 34, 761.

Explanation:

The question asks in which number does the 6 have a value that is one tenth the value of the 6 in 34, 761.

To find the answer, we need to compare the place value of the 6 in both numbers. In 34, 761, the 6 is in the thousands place, and its value is 6,000. To have a value that is one tenth of 6,000, the 6 would need to be in the hundreds place in the other number.

So, the number in which the 6 has a value one tenth the value of the 6 in 34, 761 would be 600.

Final answer:

The number 6 in 2,001.06 is one-tenth the value of the 6 in 34,761.

Explanation:

The number 6 in 34,761 has a value that is one-tenth the value of the 6 in the number 2,001.06.

To find this, we can compare the place values of the two 6's. The 6 in 34,761 is in the ones place, while the 6 in 2,001.06 is in the tenths place.

Since the tenths place is one place to the right of the ones place, the value of the 6 in 2,001.06 is one-tenth the value of the 6 in 34,761.

Consider a point on the trans-australian highway, where two old wombats live. arrivals of cars at this point follow a poisson distribution; the average rate of arrivals is 1 car per 12 seconds.

Answers

Given that the arrivals of cars at the trans-australian highway follow a poisson distribution with the average rate of arrivals as 1 car per 12 seconds.

This is a Poisson distribution with a mean of 1 car every 12 seconds.

Part A:

The probability of a Poisson distribution is given by:

[tex]P(X=x)= \frac{e^{-\lambda}\lambda^x}{x!} [/tex]

Given tha one of the old wombats requires 12 seconds to cross the highway, and he starts out immediately after a car goes by.

The probability he will survive is the probability that no car passes through the point in the next 12 seconds.

[tex]P(x=0)= \frac{e^{-1}(1)^0}{0!} =e^{-1}=0.368[/tex]

Therefore, the probability that he will survive is 0.368



Part B:

Given that at the same point of the highway there is another old wombat, slower but tougher than in the previous exercise. He requires 24 seconds to cross the road, but it takes two cars to kill him. (A single car won’t even slow him down. The arrival rate of cars is still one car per 12 seconds.)

Since the arrival rate of cars is one car per 12 seconds, then, in 24 seconds the arrival rate is 2 cars. (i.e. λ = 2)

The probability that he survives is the probability that 2 cars did not pass through the point.

[tex]P(X\neq2)=1-P(X=2)=1- \frac{e^{-2}(2)^2}{2!} =1-0.135=0.865[/tex]

We start on the ones place 6 + 1 + 2 = 9, the sum of the digits in the ones place is not up to 10, we will not regroup this ones place.

So, basically the answer to 13a is NO.
Since we are not able to regroup the ones place there is no regrouped tens to add, therefore the answer to 13b is also NO.

Next is the tens place, 4 +2 +5 = 11, the sum of the digits in the ones place is up to 10 so we regroup the tens place.

Thus, the answer to 13c is YES.

Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13d is YES.

negation of all owls fly?

Answers

Looking at this in terms of sets, let's call O the set of all owls, and F the set of all things that can fly. What this original statement is saying every animal that's a member of the set of all owls is also a member of the set of all things that can fly, or in other words, O⊂F (O is a subset of F). Negating this tells us that, while there's at least one element of O that also belongs to F, O is not contained entirely in F (O⊆F, in notation), so a good negation or our original statement might be:

162x + 731 = −y − 9x-2 vertex form

Answers

There is a typo in the quadratic term.

I am goint to solve this question assuming that the correct expression is 162x + 731 = - y - 9x^2

Now, you should know that the vertex form is y = a(x - h)^2 + k, where the vertex is (h,k).

So, we just must transform the quadratic function into that form. To do that you must complete squares. I will do it step by step

start: 162 x + 731 = - y - 9x^2

1) Transpose terms:

y = - 9x^2 - 162x + 731

2) extract common factor ot the two terms with x^2 and x.

y = - 9 (x^2 + 18x) + 731

3) complete squares for x^2 + 18x, which is (x + 9)^2 - 81

=>   y = - 9 [ ( x + 9)^2 - 81 ] + 731

4) solve the square brackets

=> y = - 9 (x + 9)^2 - 9*81 + 731

=> y = - 9(x + 9)^2 -729 + 731

=> y = - 9 (x + 9)^2 + 2

Answer: y = - 9 (x + 9)^2 + 2


Final answer:

To write the given equation in vertex form, we need to complete the square for the x terms. The vertex form of a quadratic equation is y = a(x-h)^2 + k, where (h, k) is the vertex of the parabola. After completing the square and rearranging the equation, we find that the equation in vertex form is y = 171(x + 7391/4) - 17113/4.

Explanation:

To write the given equation in vertex form, we need to complete the square for the x terms. The vertex form of a quadratic equation is given by y = a(x-h)^2 + k, where (h, k) is the vertex of the parabola.

Let's rearrange the equation to isolate the x terms on one side and the y term on the other side: 162x + 9x + y = -731 - 2

Combine like terms: 171x + y = -733

Now, we can complete the square for the x terms. Divide the coefficient of x by 2 and square the result. Add this value to both sides of the equation: 171x + y + (171/2)^2 = -733 + (171/2)^2

Simplify: 171x + y + 7391/4 = 17113/4

Finally, we can rewrite the left side as a binomial squared and simplify the right side: 171(x + 7391/4) + y = 17113/4

Therefore, the equation in vertex form is: y = 171(x + 7391/4) - 17113/4

Alan is building a garden shaped like a rectangle with a semicircle attached to one short side. If he 21) has 20 feet of fencing to go around it, what dimensions will give him the maximum area in the garden?

Answers

Let the short side be W


The half circumference of the semi-circle = .5 * pi *W


2Lengths + width + semicircle = 20 ft


2L + W + (.5*pi*W) = 20


2L + W + 1.57W = 20


Combine like terms



2L + 2.57W = 20


Simplify divide by 2


L + 1.285W = 10


L = (10 - 1.285W); for substitution:


Get the area equation:


Rectangle area + semicircle area


A = L * W + (.5*pi*(.5W) ^2)


A = LW + (1.57*.25W^2)


A = LW + .3925W^2


Replace L with (10-1.285W)


A = W(10-1.285W) + .3925W^2


A = -1.285W^2 + .3925W^2 + 10W


A = -.8925W^2 + 10W

Find W by finding the axis of symmetry of this equation a=-.8925, b=10


W = -10 / 2 * (-.8925)



W = -10 / -1.785


W = 5.60 is the width for max area


then we solve for the length


L = 10 - 1.285(5.60)


L = 10 – 7.20 = 2.8 ft is the length

Then, Check the perimeter


2(2.8) + 5.60 + 1.57(5.60) = 20ft


5.6 + 5.6 + 8.736 = 20ft


Rectangle: 2.8 by 5.60 has semicircle circumference 8.736 has a maximum area: (2.8*5.60) + (.5 * pi * 2.8 ^ 2)


=15.68 + 12.31

There is a value of $a$ such that subtracting $a-4$ from $4a+16$ gives an answer of $-25$. What is that value of $a$?

Answers

A is -15
4a + 16 - a + 4 = -25
3a + 20 = -25
3a = -45
A = -15

Answer:

a = -15

Step-by-step explanation:

Let's rewrite the exercise in math language.

We have to subtract a-4 from 4a+16 to get -25, that is

4a+16 - (a-4) = -25

The minus sign that is just before the parenthesis changes all the signs inside it. Therefore, if we want to delete the parenthesis, we need to change the signs before.

4a + 16 - a + 4 = -25

Now we can associate the terms with an a between them and the terms without it from the left side of the equation.

3a + 20 = -25

Let's subtract 20 on both sides.

3a + 20 - 20 = -25 - 20

3a = -45

Finally, we divide by 3 on both sides

3a/3 = -45/3

a = -15

given that 2/3a=16, which of the following illustrates how the multiplicative inverse property can be used to find the value of a?

Answers

multiplying both side by 3/2
2/3a×3/2 = 16×3/2
a= 8×3 = 24

Step-by-step explanation:

We have been given that [tex]\frac{2}{3}a=16[/tex].

Since multiplicative inverse property states that any number multiplied by its reciprocal is equal to one.

[tex]\frac{2}{3}\times \frac{3}{2} =1[/tex]

To solve for a let us divide 16 by [tex]\frac{2}{3}[/tex].

[tex]a=16\div \frac{2}{3}[/tex]

Since dividing a number by fraction is same as multiplying the number by the reciprocal of fraction. So we will multiply 16 by [tex]\frac{3}{2}[/tex].

[tex]a=16\times\frac{3}{2}[/tex]

[tex]a=8\times 3[/tex]

[tex]a=24[/tex]

We can see that to solve for a we have multiplied 16 by [tex]\frac{3}{2}[/tex] and [tex]\frac{3}{2}[/tex] is reciprocal of [tex]\frac{2}{3}[/tex].

Let us verify our answer by substituting a=24 in our given equation.

[tex]\frac{2}{3}\times 24=16[/tex]

[tex]2\times 8=16[/tex]

[tex]16=16[/tex]

Hence, to find the value of a we used multiplicative inverse property.

Samuel order four did from an online music stores. Each dvd cost 9.99$. He has a 20% discount code and sales tax is 6.75%. What is the total cost of the order

Answers

If Samuel ordered 4 DVDs at $9.99 each then you multiply $9.99 x 4= $39.96.  

Then you need to remember the 20% discount $39.96 - 20%= $39.96 x .20= 7.99 (if you need to show your work) Then subtract $7.99 from $39.96=$31.97 

Next you have to factor in the tax. $31.97 + 6.75% = $31.97 + 2.16= $34.13 for Samuel's total order

multiply 4 by 9.99 for cost of the 4 dvd's

9.99 *4 = 39.96

20% discount is: 39.96 *0.20 = 7.99

39.96 - 7.99 = 31.97

now add the sales tax:

31.97 * 1.0675 = 34.13

 total cost is $34.13
