The least amount of hours of footage the observers need to review to see the Cape Sable seaside sparrow and the Florida leafwing butterfly in the area at the same time is B. 36 hours.

The least common multiple (LCM) is the smallest multiple of two or more numbers.

The LCM of 9 and 4 is 36 (4 x 9).

The total number of hours of filming and recording by the stationary camera is 96.

The regularity of observing the Cape Sable Seaside Sparrows = every 4 hours

The regularity of observing the Florida Leafwing Butterfly = every 9 hours

Using their LCM as 36,

The Cape Sable Seaside Sparrows will be observed 9 times when they meet the Florida Leafwing Butterfly at its 4th observation.

Thus, the least amount of hours of footage the observers need to review to see the Cape Sable seaside sparrow and the Florida leafwing butterfly in the area at the same time is B. 36 hours.

Answer: 68

Step-by-step explanation: do 75+37 which equals 112 then subtract 180 by 112 which equals 68

hope this helps

Answer:

A

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , then

x + 37° + 75° = 180° , that is

x + 112° = 180° ( subtract 112° from both sides )

x = 68°

The value of 5x + 5y is 2500 by substitution method.

According to the given question.

We have two equations

2x + 3y = 1200

3x + 2y = 1300

Since, we have to find the value of 5x + 5y by substitution method.

From equation 2x + 3y = 1200

2x = 1200 - 3y

⇒ x = [1200 -3y]/2

Substitute the value of x in 3x + 2y = 1300.

⇒ 3[1200 - 3y]/2 + 2y  = 1300

⇒   3[600 -3y/2] + 2y = 1300

⇒ 1800 - 9y/2 + 2y  = 1300

⇒ 1800 + (4y - 9y)/2  = 1300

⇒ (4y - 9y)/2  = -500

⇒ -5y = -1000

⇒ y = 200

So,

x = [1200 - 600]/2  = 600/2 = 300

Thereofore, the value of 5x + 5y by substitution method is given by

5(300) + 5(200)

= 1500 + 1000

= 2500

Hence, the value of 5x + 5y is 2500 by substitution method.

The increase in the money supply that causes prices to rise and leads to inflation, loses purchasing power.

What is inflation?

Inflation refers to the persistent rise in the general prices of commodities in the economy over a period of time. If the prices of goods and services increase in an economy without an increase in income of people, it reduces the purchasing power of individuals.

This follows the law of demand which states that; the higher the price, the lower the quantity demanded; the lower the price, the higher the quantity demanded.

Answer:

f(5) = 104

Step-by-step explanation:

To find the value of f(5), we have to plug in 5 into our equation f(x) = 20x + 4.

f(5) = 20(5) + 4

Following our order of operations, we multiply first, then add to get our answer.  

f(5) = 20(5) + 4

f(5) = 100 + 4

f(5) = 104

Answer:

Never true

Step-by-step explanation:

2x - 5 < 2(x - 3) first multiply 2 with the inside the parenthesis

2x - 5 < 2x - 6

now when we simplify the inequality 2x on the both sides will be eliminated and we will be left with:

(-5) < (-6) which cannot be true because (-5) is closer to 0 in number line so it's bigger then (-6) not smaller

Therefore the answer is "Never true"

Answer:

−[tex]x^{2}[/tex] + 9x + 1

Step-by-step explanation:

Answer:

Domain: [tex]x > -5[/tex] or [tex](-5,\infty)[/tex]

Range: [tex]y\geq -3[/tex] or [tex][-3,\infty)[/tex]

Step-by-step explanation:

The domain is essentially the set of x-values in a given graph. In this graph. we see that the lowest x-value is an unfilled dot when x=-5. The unfilled dot means that the function [tex]f(x)[/tex] doesn't include -5. We then see that the x-value goes to positive infinity. This means that [tex]x[/tex] must be greater than -5. It is not greater or equal to -5 because the dot is not filled.

Therefore, we have that [tex]x > -5[/tex]. To convert to interval notation we can take the lower value (-5) and put it on the left side and put the higher value ([tex]\infty[/tex]) and put it on the right side. Since the graph doesn't include -5, we can put parentheses around both values to get [tex](-5,\infty)[/tex].

Note: We always put parentheses around both [tex]\infty[/tex] and [tex]-\infty[/tex].

The range is basically the same as the domain but with the y-value. We can see that the lowest y-value is y=-3. This includes -3 since the line fills the point in. Then we see that the highest y-value is once again positive infinity. This means that [tex]y\geq-3[/tex].

Now when we convert to interval notation, we have -3 and [tex]\infty[/tex]. This time since y=-3 is included in the function, we put a hard bracket around -3. Thus, we get [tex][-3,\infty)[/tex].

Answer:

88 is the answer to the question

The value of f(0) is -1

A function can be defined as an expression, law or rule that explains the relationship between two variables; a dependent and an independent variable.

Given the function;

f(x)= -x - 1

To determine f(0), we substitute the value of x as 0 in the function

So, we have;

f(0) = -(0) - 1

f(0) = -0 - 1

f(0) = -1

Thus, the value of f(0) is -1

Step-by-step explanation:

What Is the Square Root of 175? The square root of 175 is defined as the value obtained on the multiplication of an integer by itself which will give the final product as 175. As there is no such integer which on multiplication with itself will give 175 exactly, the square root of 175 is not a whole number.

The Solution in inequality form is 7 ≤ x ≤ 10.

The Solution in interval notation: [7,10].

Given the data in the question;

-x - 8 ≤ -15 and -18 ≤ -x - 8

To solve, simplify the first part of the inequality by solving for x.

-x - 8 ≤ -15

Add 8 to both sides

-x - 8 + 8 ≤ -15 + 8

-x ≤ -7

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

-x/-1 ≥ -7/-1

x ≥ 7

Next, simplify the second part of the inequality by solving for x

-18 ≤ -x - 8

Rewrite as

-x - 8 ≥ -18

Add 8 to both side

-x - 8 + 8 ≥ -18 + 8

-x ≥ -10

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

-x/-1 ≤ -10/-1

x ≤ 10

Now, the intersection consist of the elements that are contained in both intervals.

The probability of either A or B occurring will be 0.8.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Being connected in a way that one excludes or prevents the other events from happening also: completely at odds despite the fact that their viewpoints did not conflict.

Suppose that A and B are mutually exclusive events for which P(A) = 0.3 and P(B) = 0.5.

Then the probability of either A or B occurring will be

P(AUB) = P(A) + P(B)

P(AUB) = 0.3 + 0.5

P(AUB) = 0.8

The probability of either A or B occurring will be 0.8.
