Answer: 31, 680 feet

Step-by-step explanation:

If 5280 feet = 1mile

x = 6 miles

Step 1: cross multiply the equation to the the value of x

x= 5280 × 6

=31,680 feet

Step-by-step explanation:

B

for a square diagonal is found by using pythagoras theorem.

(30)²+30²=900+900=1800≠45²

The best describes the shape of the baseball field would be; B Not square (30)² + 30² ≠45².

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Giselle is building a small baseball infield for her brother.

The infield should be in the shape of a square.

Each side of the infield, between bases, measures 30 feet.

The distance between home plate and second base, as shown in the picture, is 45 feet.

A square diagonal can be calculated by using the Pythagoras theorem.

|AC|^2 = |AB|^2 + |BC|^2    

= (30)² + 30²

= 900 + 900

= 1800

≠45²

Step-by-step explanation:

Points to remember

midpoint formula

Length of a line segment with endpoints (x1, y1) and (x2, y2) is given by,

Midpoint= [(x2 + x1)/2 , (y2 + y1)/2]

To find the midpoint of EC

Let   (x1, y1) = E(2t, 0) and  (x2, y2) = C(2p, 2r)

Midpoint = [(2t + 2p)/2 , (0 + 2r)/2]

= (2(t + p)/2 , 2r/2)

= (t + p, r)

Therefore midpoint of EC = (t + p, r)

The correct answer is first option

The other measurement of the golden rectangle is approximately 9.1 inches.

A golden rectangle is defined by the property that the ratio of its length to its width is equal to the golden ratio, which is approximately 1.61803398875. This ratio is often denoted by the Greek letter phi (φ).

Given that one measurement of the golden rectangle is 5.7 inches, we can denote this as the width, w. To find the length, l, we use the golden ratio formula:

[tex]\[ l = w \times \phi \][/tex]

Substituting the given width and the value of φ:

[tex]\[ l = 5.7 \text{ inches} \times 1.61803398875 \][/tex]

[tex]\[ l \approx 9.1 \text{ inches} \][/tex]

Therefore, the other measurement of the golden rectangle, which is the length, is approximately 9.1 inches.

Answer:

24 cups

Step-by-step explanation:

Peaches to Cherries is given as 2 to 3

We can think of this as "parts". So total parts in the salad would be:

Total Part = 2 + 3 = 5 parts

So, now we need cups of peaches to cups of TOTAL

The ratio would be:

2 : 5

The total would be 60 cups

We let total cup of peaches be x

So we can write the ratio:

[tex]\frac{2}{5}=\frac{x}{60}[/tex]

Now, we cross multiply and solve for x:

[tex]\frac{2}{5}=\frac{x}{60}\\5x=2*60\\5x=120\\x=24[/tex]

Fred will need 24 cups of peaches

Answer:

  $361,223

Step-by-step explanation:

Each year, the value is multiplied by 1+5% = 1.05. After 51 years, it has been multiplied by that factor 51 times, so is now ...

  $30,000×1.05^51 ≈ $361,223

Final answer:

To find the approximate value of land purchased for $30,000 in 1960 with a 5% annual increase by 2011, we use the compound interest formula which results in an approximate value of $447,187.25.

Explanation:

To determine the approximate value of land in the year 2011, which was purchased for $30,000 in 1960 with an average annual increase of 5%, we will use the formula for compound interest. This situation can be treated as a compound interest problem where the initial principal is the initial land value, the rate is the annual increase, and the time is the number of years the land has appreciated.

The compound interest formula is [tex]A = P(1 + r/n)^(nt),[/tex] where A is the future value of the investment/loan, including interest, P is the principal investment amount (initial value of land), r is the annual interest rate (annual increase in value), n is the number of times that interest is compounded per year, and t is the time the money is invested or borrowed for, in years.

In this scenario, P is $30,000, r is 0.05 (5% expressed as a decimal), n is 1 since we are compounding annually, and t is 51 (2011 - 1960).

Therefore,

[tex]A = 30,000(1 + 0.05/1)^(1*51).[/tex]

Carrying out the calculation gives us the approximate value of the land in 2011.

[tex]A = 30,000(1.05)^51[/tex]
Approximate value of the land in 2011 = $447,187.25

A total of 90 bricks were laid that day.

Step-by-step explanation:

Given,

Number of bricks laid in one hour = 27

This represents 30% of total bricks laid that day.

Let,

x be the total number of bricks laid that day.

30% of x = 27

[tex]\frac{30}{100}*x=27\\0.3x=27[/tex]

Dividing both sides by 0.3

[tex]\frac{0.3x}{0.3}=\frac{27}{0.3}\\x=90[/tex]

A total of 90 bricks were laid that day.

x + y = 9

x = 9 - y

2x - y = 0

2(9 - y) - y = 0

18 - 2y - y = 0

-3y = -18

y = 6

x = 9 - y

x = 9 - 6

x = 3

The value of x and y are 3 and 3 respectively in the given system of equations.

A system of equations is a set of two or further equations that own an identical set of unknowns. The thing of solving a system of equations is to determine the values for the unknowns that quench all of the equations in the system.

It is given that the system of equations is,

2x - y = 0

x + y = 9

Now, from the first equation, we get

y = 2x

On putting the above value of y in the second equation, we get

x + 2x = 9,

3x = 9,

x = [tex]\frac{9}{3}[/tex]

x = 3.

Now putting this value of x in the first equation, we get

2 [tex]\times[/tex] 3 + y = 9

6 + y = 9

y = 9 - 6

y = 3.

So, x = 3 and y = 3 in the above system of equations.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that,

x^8/x^a=x²

Applying indices

Division rule a^m ÷ a^n = a^(m-n)

Then,

x^8/x^a=x²

x^(8-a)=x²

For this to be equal means that, the power are equals since they have the same base

Then, 8-a=2

8+2=a

So, a=10

Taking the second equation

(x^6)^b=x¹²

Using indices again

x^(6b)=x¹²

Also, for this to be equal

6b=12

Then, b=12/6

b=2

Then, b=2 and =10

We need to find b-a.

b-a=2-10=-8

Then, the answer to b-a is -8

C. Coordinates of D' (-6,3)

Step-by-step explanation:

When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.

(x, y) → (-x, -y)

The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,

A (7,-7) → A'(-7,7)

B (4,-10) → B' (-4,10)

C (1.5, -2.5) → C' (-1.5, 2.5)

D (6, -3) → D'(-6,3)

So the coordinates of D' will be (-6,3)

Answer:

Step-by-step explanation:

41%

(a) P(X = 3) ≈ 0.2687

(b) P(X ≥ 4) ≈ 0.9852

(c) P(X < 8) ≈ 0.9998

These probabilities were calculated using the binomial probability formula for a 41% favorability rate and 12 trials.

To find the probability in this scenario, we can use the binomial probability formula. Let's break down each part of the question:

(a) To find the probability that exactly three out of twelve U.S. adults favor the use of unmanned drones, we can use the binomial probability formula:

P(X = k) = (n choose k) ×[tex]p^k[/tex] ×[tex](1-p)^(n-k)[/tex]

Where:

n is the number of trials (12 in this case).

k is the specific number of successes we're interested in (3 in this case).

p is the probability of success (41% or 0.41 in decimal form).

P(X = 3) = (12 choose 3) × [tex](0.41^3)[/tex] × [tex](0.59^9)[/tex]

Calculate this using a binomial calculator or software to find the exact probability.

(b) To find the probability that at least four out of twelve U.S. adults favor the use of drones, we need to calculate the complementary probability of having fewer than four favoring drones and subtract it from 1:

P(X ≥ 4) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)]

(c) To find the probability that less than eight out of twelve U.S. adults favor the use of drones, calculate:

P(X < 8) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 7)

You can compute these probabilities using a binomial calculator or statistical software to get the precise answers.
