Answer:

Step-by-step explanation:

Since Rick has 40ft of fencing

Then, the perimeter cannot be more than 40ft if he decided to lay the block on a single layer and not on each other

Then if the length is x

And the breadth is y

Perimeter of a rectangle is 2(l+b)

Therefore,

Perimeter is less than or equal to 40ft

2(l+b)  ≤ 40

b.  2(l+b)≤ 40

Then divide both side by 2

l+b≤ 20.

Then l ≤ 20-b

Also, b ≤ 20-l

Answer:

19

Step-by-step explanation:

If the scientist chooses 60 random eggs then the overall probability of selecting yellow eggs is 32%. So, there's a chance of he randomly collecting 60 eggs out of which 19 could be yellow.

(60/100) x 32 ~ 19...

The usual number of yellow dragon eggs expected in a sample of 60, given a 32% probability, is 19 when rounded to the nearest whole number.

The question at hand involves finding the expected number of yellow eggs in a sample size of 60, given a known probability of a yellow egg occurrence.

Since we know that 32% of the dragon eggs on planet Pern are yellow, we can calculate the usual number of yellow eggs in the samples by multiplying the sample size (60 eggs) by the probability of getting a yellow egg (0.32).

Therefore, the expected or usual number of yellow eggs in the sample would be 60 × 0.32 = 19.2.

Considering that we cannot have a fraction of an egg, the usual number of yellow eggs in samples of 60 eggs would typically be rounded to the nearest whole number, which is 19.

Answer:

27° (as an integer)

Step-by-step explanation:

From the figure given;

DC = 8 units

BC = 4 units

We are required to determine m∠D

We need to use the appropriate trigonometric ratio;

In this case, DC is adjacent and BC is opposite to m∠D

Therefore, the appropriate trigonometric ratio is tangent;

That is;

Tan m∠D = BC ÷ DC

               = 4 ÷ 8

               = 0.5

Thus;

m∠D = Tan^-1 (0.5)

        = 26.57

         = 27 (as an integer)

Thus, m∠D is 27°

Step-by-step explanation:

Let x represent time taken to complete 300 miles.

We have been given that Bryce a previous winner of the contest, made a trip of 360 miles in a 6.5 hours.

We will use proportions to solve our given problem since rates are same for both distances.

[tex]\frac{\text{Distance covered}}{\text{Time taken}}=\frac{360\text{ Miles}}{6.5\text{ Hours}}[/tex]

Upon substituting our given values in above proportion, we will get:

Let u represent the unit price of the 100 lb container. Then u+.06 is the unit price of the 75 lb container.

The difference in prices is ...

  100u - 75(u+.06) = 55.50

  25u -4.50 = 55.50

  25u = 60

  u = 60/25 = 2.40

The cost of the 100 lb container is 100u = 240. The cost of the 75 lb container is $55.50 less: 240 -55.50 = 184.50.

The 100 lb container costs $240. The 75 lb container costs $184.50.

Answer:

Step-by-step explanation:

We take a methodical approach by considering the different possible values of b when asqrtb is the simplest form of sqrtn.

Case 1: b=1. We can't forget the perfect squares! If n=100, for example, then sqrt100 can be written as 10sqrt1. So, we must include the perfect squares from 10^2=100 up through 22^2 = 484. (All greater squares are greater than 500.) There are 13 such squares.

Case 2: b=2. If b=2, then we have asqrtb = asqrt2 = sqrta^2 x sqrt2 = sqrt2a^2. We still must have a {>_} 10, but now we need 2a^2 to be no greater than 500. This means that a^2 must be no greater than 250, so a can be 10, 11, 12, 13, 14, or 15. There are 6 such values.

Case 3: b=3. We then have asqrtb = asqrt3 = sqrt3a^2. Since 3a^2 {<_} 500, we know that a^2 is less than 167. We still need a {>_} 10, so there are only 3 values of a in this case: 10, 11, 12.

We skip b=4 because then asqrtb would not be in simplest form.

Case 4: b=5. We then have asqrtb = sqrt5a^2, and a=10 is the only possible value for this case.

For any greater value of b, the resulting value of n is greater than 500 when a {>_} 10. So, there are no more possible numbers asqrtb that satisfy the problem. Since each of the 13+6+3+1 = 23 possibilities listed above represent different simplified forms, they give us 23 different possible values of n that satisfy the problem.

There are infinitely many positive integers less than 500 that have square roots in the form of a√b, where a and b are integers with a≥10.

The number of such positive integers n is infinite, as there is no finite value for the count.

Here,

We are looking for positive integers n that are less than 500.

The square roots of these integers can be expressed in the form a√b.

And [tex]a\ge 10[/tex]

To find the number of positive integers less than 500 that have square roots in the form of a√b,

Analyze the possible values of a and b separately:

For a,

We know that it must be an integer greater than or equal to 1. So,

We have a total of a = 10, 11, 12  ..., and so on. (since a ≥ 10)

As for b,

it can be any perfect square less than or equal to 500.

Let's list a few examples:

b = 1, since 1√1 = 1

b = 4, since 1√4 = 2

b = 9, since 1√9 = 3

b = 16, since 1√16 = 4

...

b = 484, since 1√484 = 22

Now, we can count the number of possibilities for a and b.

We have an infinite number of possibilities for a, but b has a finite number of perfect squares less than or equal to 500.

There are 22 perfect squares within this range.

Therefore, the total number of positive integers n, with n < 500, that have square roots in the form of a√b is 22 x infinity = infinity.

Since there are infinitely many possible values for n,

Hence,

We can conclude that there is no finite value for the number of positive integers n that satisfies this condition.

Answer:

Step-by-step explanation:

The current global population is growing at an annual rate of 1.35 percent. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 6.1 × 10^9

r = 1.35% = 1.35/100 = 0.0135

t = 1

Therefore

A = 6.1 × 10^9(1 + 0.0135)^1

A = 6.1 × 10^9(1.0135)^1

A = 6182350000

The number of people that would be added is

6182350000 - 6100000000

= 82350000

If the world population were to keep growing at 1.35%, we number of people who would be added next year is 82,350,000 people.

The population of the world is growing at 1.35%. This means that next year, the number of people added will be 1.35% of the current population.

The current population is 6.1 billion so the number of people who will be added is:

= Population x Incremental rate

= 6,100,000,000 x 1.35%

= 82,350,000 people

In conclusion, 82,350,000 people will be added.

The height of the wall is 52.2 feet.

Step-by-step explanation:

Given:

From the figure shown, HT is the height of Carlos, 'V' is the position of mirror.

So, TV = 4 ft, VS = 36 ft, HT = 5.8 ft.

Let the height of the wall be 'x'. So, JS = 'x'

Now, consider the two triangles HTV and JVS

Statements                                                               Reasons

1. ∠ HTV ≅ ∠ JSV                                           Right angles are congruent

2. ∠ HVT ≅ ∠ JVS                                          Given in the figure

Therefore, ΔHTV and Δ JVS are similar triangles by AA postulate.

Now, from definition of similar triangles, corresponding sides of two similar triangles are in proportion to each other. Therefore,

[tex]\frac{HT}{JS}=\frac{TV}{VS}=\frac{HV}{JV}[/tex]

Considering the first two pair of fractions, we have:

[tex]\frac{5.8}{x}=\frac{4}{36}\\\\36\times 5.8=4\times x\\\\x=\frac{36\times 5.8}{4}\\\\x=9\times 5.8=52.2\ ft[/tex]

Therefore, the height of the wall is 52.2 feet.

Final answer:

To calculate the cost, multiply the amount of turkey per student (0.3 pounds) by the number of students (100), then multiply the total pounds needed (30) by the cost per pound ($0.79), resulting in a total cost of $23.70 for turkey for 100 students.

Explanation:

The question asks us to calculate the cost of providing turkey to 100 students if each student requires 0.3 pounds of turkey, and turkey costs $0.79 per pound. To find the total amount of turkey needed, we multiply the amount each student gets by the total number of students: 0.3 pounds/student × 100 students. This calculation results in 30 pounds of turkey required for 100 students.

Next, to determine the total cost, we multiply the total pounds of turkey needed by the cost per pound: 30 pounds × $0.79/pound. This calculation gives us a total cost of $23.70 for the turkey.

Therefore, it will cost $23.70 to give turkey to 100 students.

Answer:

[tex]y=-\frac{74}{21}x+452[/tex]

Step-by-step explanation:

Given:

The level of a lake is falling linearly.

On Jan 1, the level is 452 inches

On Jan 21, the level is 378 inches.

Now, a linear function can be represented in the form:

[tex]y=mx+b[/tex]

Where, 'm' is the rate of change and 'b' is initial level

[tex]x\to number\ of\ days\ passed\ since\ Jan\ 1[/tex]

[tex]y\to Lake\ level[/tex]

So, let Jan 1 corresponds to the initial level and thus b = 452 in

Now, the rate of change is given as the ratio of the change in level of lake to the number of days passed.

So, from Jan 1 to Jan 21, the days passed is 21.

Change in level = Level on Jan 21 - Level on Jan 1

Change in level = 378 in - 452 in = -74 in

Now, rate of change is given as:

[tex]m=\frac{-74}{21}[/tex]

Hence, the function to represent the lake level is [tex]y=-\frac{74}{21}x+452[/tex]

Where, 'x' is the number of days passed since Jan 1.

Final answer:

The lake level can be represented by a linear function L(t) = -3.7t + 452, where L(t) is the lake level in inches and t is the time in days from January 1st.

Explanation:

To find a function representing the lake level as it drops linearly over time, we need to determine the linear equation that corresponds to the change in the lake level.

We are given that the lake level is 452 inches on January 1st and 378 inches on January 21st.

First, we will define the variables where L(t) is the lake level in inches and t is the time in days with t=0 corresponding to January 1st.

We are given two points on the linear function: (0, 452) and (20, 378), since January 21st is 20 days after January 1st.

Next, we calculate the slope of the line using the formula:

slope = (change in lake level) / (change in time) = (378 - 452) / (20 - 0) = -74 / 20 = -3.7 inches per day.

Now, we can use the slope and a point to write the equation of the lake level as a function of time in the slope-intercept form:

L(t) = mt + b

where m is the slope and b is the y-intercept. Plugging in the slope and the point (0, 452):

L(t) = -3.7t + 452

This equation represents the function of the lake level over time.

the equations are:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

[tex]\[ a^2 = c^2 - b^2 \][/tex]

[tex]\[ b^2 = c^2 - a^2 \][/tex]

In a right triangle, according to the Pythagorean theorem, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. So, we have:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

This equation represents the relationship among the side lengths of a right triangle.

Therefore, the equations are:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

[tex]\[ a^2 = c^2 - b^2 \][/tex]

[tex]\[ b^2 = c^2 - a^2 \][/tex]

This completes the three relations among a, b, andc.

To find the time, we require:

Speed:

This is given in the question as 4 ft/ sec.

Distance:

On a circle, the distance from the end of the circle to the centre is referred to as "Radius". We shall assume the radius here is [tex]r[/tex].

To calculate the radius, we can use the formula of the circumference: [tex]C = 2 \pi r[/tex]

Were are given that C = 628 feet.

Using the formula: [tex]r = \frac{628}{2 \pi} = 100\ feet[/tex]

The distance the boat needs to travel is 100 feet.

Time:
