In order to determine which equation represents the boundary, replace the values of the coordinates of the given points, into the choices for the equations, and then verify if the left hand side matches with the right hand side.

For points (35,0) and (5,0) you have:

x = 35

y = 0

x = 5

y = 0

Then, for the first answer choice we have:

As you can notice, the equation matches for values of x and y.

Then, there is no necessary to verify for the other choices.

Hence, the equation (x - 20)^2 + y^2 = 225 represents the boundary that the sprinkler covers.

The simplified expression of the fraction expression is (b) One group of 4/6, with 1/6 remaining.

The fraction expression is given as

ten StartFraction 1 Over 12 EndFraction bars.

Rewrite the fraction properly

So, we have

Ten 1/12 bars

This can be represented as

10 * 1/12

Rewrite 10 as 10/1

So, we have the following equation

10 * 1/12 = 10/1 * 1/12

Evaluate the products of the numerator

So, we have the following equation

10 * 1/12 = 1/1 * 10/12

Evaluate the products of the denominator

So, we have the following equation

10 * 1/12 = 10/12

Simplify the fraction

10 * 1/12 = 5/6

Split the fraction

10 * 1/12 = 4/6 + 1/6

This means that, the result is

Quotient = 4/6 and remainder = 1/6

We want to find the distance that the top edge of the calendar is from the ceiling.

The diagram below will help us

From the diagram above x is the distance we want to find

We can see that the entire wall is 9 ft long,

Distance from the foot of the calender to the floor is 5 1/4 ft and

Halve of the calendar is 2/3 ft

So the whole calendar is

So, to find x, we will add length of the calendar which is 4/3 ft to distance from the foot of the calender to the floor which is 5 1/4 ft and subtract this from height of the wall which is 9 ft

We have

Hence the answer is

The value of the missing angles are; m∠ABC = 36° and m∠DBC = 41°

We are given that;

m∠ABD = 77°

Addition angle postulate states that the sum of two adjacent angle measures will equal the angle measure of the larger angle that they form together.

Now, by addition angle postulate, we can say that;

m∠ABC + m∠DBC = 77°

Now, we are given that;

m∠ABC = (5x - 4)°

m∠DBC = (5x + 1)°

Thus, by substitution property, we have;

(5x - 4)° + (5x + 1)° = 77

10x - 3 = 77

10x = 77 + 3

10x = 80

x = 8

Thus;

m∠ABC = (5(8) - 4)°

m∠ABC = 36°

m∠DBC = (5(8) + 1)°

m∠DBC = 41°

For 1 cup of blue paint, 1/4 cups of black paint is needed

The given parameters are

8 cups of blue paint needed for 2 cups of black paint

This means that

8 cups of blue paint needed = 2 cups of black paint

Divide both sides of the equation by 8

So, we have the following equation

8/8 cups of blue paint needed = 2/8 cups of black paint

Evaluate the quotient

So, we have the following equation

1 cup of blue paint needed = 1/4 cups of black paint

To find how many Costco employees are, we can use the formula of

A function that models the population of 400 birds decreasing at an annual rate of 6% is  [tex]f(x) = 400(1 - 0.06)^{t}[/tex] where t is the time period.

The Exponential decay formula aids in determining the quick decrease over time, i.e. the exponential decrease. The exponential decay formula is used to calculate population decay, half-life, radioactivity decay, and so on.

Its general form is f(x) = a (1 - r)ⁿ.

Where a = the initial amount

1 - r = decay factor and n = time period.

Given:

The initial population of birds, P = 400

Rate of decay, r = 6% = 0.06

Time = t years

By using the exponential decay formula,we get

[tex]f(x) = P (1 - r)^{t}[/tex]

[tex]f(x) = 400(1 - 0.06)^{t}[/tex]

Therefore, the function that models the population of 400 birds decreased at an annual rate of 6% is  [tex]f(x) = 400(1 - 0.06)^{t}[/tex].

The three consecutive integers according to the expression will be 6, 8, 10

In the given question, there is an expression stated that tells the condition for a sequence in which a number is represented by 'n'. The expression is the sum of three even integers whose sum is equal to four times the smallest of numbers.

The expression is n + (n + 2) + (n + 4) = 4n. We have to find out the values for each of the numbers.

Here, First Number = n

Second number = (n + 2)

Third Number = (n + 4)

Now, We will calculate the given expression to find out the value of n.

=> n + (n + 2) + (n + 4) = 4n

=> 3n + 6 = 4n

=> n = 6

We get the smallest number n = 6 which is the first number, the second number is 8, and the third number is 10.

Hence, the numbers are 6, 8, and 10.

Step-by-step explanation:

probabilities are always

desired cases / totally possible cases

24 cans in total, 4 of them are diet, therefore 20 of them are regular.

2 cans are picked.

for the first can

the probability to pick a diet can is

4/24 = 1/6

the probability to pick a regular is

20/24 = 5/6

a)

to pick 2 diets, the first one has to be diet.

that leaves 23 cans with 3 being diet.

so, the probability for the second can being diet too is

3/23.

as combined event the probability to pull 2 diet cans is

1/6 × 3/23 = 1/2 × 1/23 = 1/46 = 0.02173913...

≈ 0.0217

b)

now the same for picking 2 regular cans.

the first one has to be regular :

5/6

that leaves for the second one 23 cans and 19 of them regular

19/23

combined this gives the probability

5/6 × 19/23 = 95/138 = 0.688405797...

≈ 0.6884

this is not unusual.

what would be considered "usual" or "unusual" ?

c)

one of them is diet, and one of them is regular.

the simple answer ?

it is the only other option, when the cans are not of the same type. it is the opposite of the sum of a) and b).

so, it is

1 - 0.688405797... - 0.02173913 = 0.289855072...

≈ 0.2899

but what to do, if we want to calculate it directly ?

it is the case that either

1. the first can is diet and the second can is regular,

or

2. the first can is regular and the second can is diet.

case 1.

the first can is diet = 1/6

leaving 23 cans with 20 being regular

the second can being regular = 20/23

together

1/6 × 20/23 = 1/3 × 10/23 = 10/69 = 0.144927536...

case 2.

the first can is regular = 5/6

leaving 23 cans with 4 diets.

the second can being diet = 4/23

together

5/6 × 4/23 = 5/3 × 2/23 = 10/69 = 0.144927536...

in an "exclusive or" situation we can add the probabilities.

so, the probability of having exactly one can diet and exactly one can regular is

0.144927536... + 0.144927536... = 0.289855072...

≈ 0.2899
