What is the length of a garden hose that is stretched diagonally corner-to-corner across a yard that measures 72 meters long and 60 meters wide? Round to the nearest meter.

Answers

Use the Pythagoras theorem :-

length  = sqrt (72^2 + 60^2)
            =   94 meters to nearest meter

Here, we need to find the length of the hose which is diagonally placed in the rectangular garden.

The length is given as = 72 meters

The width is given as = 60 meters

We will use Pythagoras theorem here.

Hypotenuse² = Perpendicular² + Base²

Hypotenuse² = 72² + 60²

Hypotenuse² = √8,784 meters²

Hypotenuse = 93.72 meters

Thus, the length of diagonal hose will be = 93.72 meters


George purchased a new car with the special 2.9% financing. If the car's price was $19,999 and he financed it for five years, find his monthly payment.


A. $357.46

B. $358.47

C. $199.99

D. $343.25

Answers

Monthly payments amount (P) is given by the following expression:

P = C*{(i/12)/[1-(1+i/12)^-12t}
C = Cost of the car = $19,999; i = financing rate = 2.9% = 0.029; t = time of payment in years = 5 years

Therefore,
P = 19999*{(0.029/12)/[1-(1+0.029/12)^-12*5} = $358.47

B. is the correct answer.

Correct Answer is B which is $ 358.47 for monthly payment

A random sample is a subset of a population where every individual has an equal and known chance of being selected, providing a representative segment for study.

A random sample is a sample in which each member of the population has a known, nonzero, chance of being selected for the sample. This means that in a random sample, every individual in the larger population has an equal opportunity to be included. There are various methods to achieve a random sample, such as simple random sampling, stratified sampling, or using random digit dialing. Random samples are crucial because they tend to be representative of the population, thereby allowing the results of studies to be generalizable.

The problem is to calculate the angles of the triangle. However, it is not clear which angle you have to calculate, so we are going to calculate all of them

we know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos C------> cos C=[a²+b²-c²]/[2*a*b]
a=12.5
b=15
c=11
so
 cos C=[a²+b²-c²]/[2*a*b]--->  cos C=[12.5²+15²-11²]/[2*12.5*15]
cos C=0.694------------> C=arc cos (0.694)-----> C=46.05°-----> C=46.1°

applying the law of sines calculate angle B
15 sin B=11/sin 46.1-----> 15*sin 46.1=11*sin B----> sin B=15*sin 46.1/11
 sin B=15*sin 46.1/11-----> sin B=0.9826----> B=arc sin (0.9826)
B=79.3°

calculate angle A
A+B+C=180------> A=180-B-C-----> A=180-79.3-46.1----> A=54.6°

the angles of the triangle are
A=54.6°
B=79.3°
C=46.1°

Kevin and randy muise have a jar containing 68 ​coins, all of which are either quarters or nickels. the total value of the coins in the jar is ​$13.40. how many of each type of coin do they​ have?

Answers

For this case, the first thing we must do is define variables:
 x: number of quarters
 y: number of nickels
 We now write the system of equations:
 x + y = 68
 0.25x + 0.05y = 13.40
 Solving the system we have:
 x = 50
 y = 18
 Answer:
 
they have:
 
quarters = 50
 
nickels = 18
Final answer:

Kevin and Randy have 50 quarters and 18 nickels.

Explanation:

To solve this problem, we can set up a system of equations. Let's use the variables x for the number of quarters and y for the number of nickels. We can then write two equations based on the given information:

Equation 1: x + y = 68 (the total number of coins is 68)

Equation 2: 0.25x + 0.05y = 13.40 (the total value of the coins is $13.40).

We can start by solving Equation 1 for x in terms of y:

x = 68 - y. Now we can substitute this expression for x into Equation 2:

0.25(68 - y) + 0.05y = 13.40

Simplifying, we get 17 - 0.25y + 0.05y = 13.40.

Combining like terms, we have 0.20y = 3.60.

Dividing both sides by 0.20, we find y = 18. Plugging this value back into Equation 1, we can solve for x:

x + 18 = 68

x = 68 - 18 = 50.

Therefore, Kevin and Randy have 50 quarters and 18 nickels.

A ball is thrown downward from the top of a 190​-foot building with an initial velocity of 21 feet per second. the height of the ball h after t seconds is given by the equation h equals negative 16 t squared minus 21 t plus 190. how long after the ball is thrown will it strike the​ ground?

Answers

To solve this problem you must apply the proccedure shown below:

 1- You have the following information give in the problem above:

 - The ball is thrown downward from the top of a 190​-foot building with an initial velocity of 21 feet per second.
- The height of the ball h after t seconds is given by this equation: h=-16t²-21t+190.

 2- h=0 when the ball strikes the ground, then you have:

 -16t²-21t+190=0

 3. When you solve the quadratic equation shown above, you obtain:

 t=2.85 seconds

 The answer is: 2.85 seconds.

The ball hits the ground after approximately 4.16 seconds.

To find the time at which the ball strikes the ground, we need to determine when h(t) = 0. Given the equation for height:

[tex]\[ h(t) = -16t^2 - 21t + 190 \][/tex]

we can set h(t) to 0 and solve for t:

[tex]\[ -16t^2 - 21t + 190 = 0 \][/tex]

Using the quadratic formula, we can find the roots of this equation:

[tex]\[ t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

where a = -16 , b = -21, and c = 190. Plugging in the values, we get:

1. Find the discriminating value [tex]\( \Delta = b^2 - 4 \times a \times c \)[/tex]:

[tex]\[ \Delta = (-21)^2 - 4 \times (-16) \times 190 = 441 + 12160 = 12601 \][/tex]

2. Calculate the roots:

[tex]\[ t = \frac{-(-21) \pm \sqrt{12601}}{2 \times -16} \\ \[ t = \frac{21 \pm \sqrt{12601}}{-32} \][/tex]

Since we're interested in the positive value (representing the time when the ball hits the ground), we'll only consider the root with the "minus" sign:

[tex]\[ t = \frac{21 - \sqrt{12601}}{-32} \approx \frac{-21 + \sqrt{12601}}{32} \approx \frac{21 - \sqrt{12601}}{32} \][/tex]

Using a calculator, let's approximate the result:

[tex]1. Compute \( \sqrt{12601} \approx 112.24 \),\\2. Then calculate \( 21 + 112.24 \approx 133.24 \),\\3. Divide by 32 to get \( t \approx \frac{133.24}{32} \approx 4.16375 \).[/tex]

Rounding to a more readable result, we can say that the ball hits the ground after approximately 4.16 seconds.

Final answer:

This question is about exponential growth and the rabbit population on an island.

Explanation:

The subject of this question is Mathematics. Specifically, it involves exponential growth and a function that represents the rabbit population on the island over time. Let's define the function f(x) to represent the population of rabbits at year x.

Based on the information given, the initial population is 20 rabbits. The population triples every year, which means that for each year x, the population is f(x) = 20 * 3^x.

For example, after 1 year, the population would be f(1) = 20 * 3^1 = 60 rabbits. After 2 years, the population would be f(2) = 20 * 3^2 = 180 rabbits, and so on.

Answers

The complete question is :

The total height of the Statue of Liberty and its pedestal is 305 feet. This is 153 more than the height of the statue. Write and solve an equation to find the height h (in feet) of the statue.

Question says 153, so we add 153 with the height of the statue

The total height of the Statue of Liberty = Height of the statue + 153

305 = h + 153

To find out h we subtract 153 on both sides

305 - 153 = h + 153 - 153

h = 152

The height of the statue = 152 ft


The height of the statue is 152 feet.

Let's call the height of the statue "h" in feet. According to the problem, the total height of the Statue of Liberty and its pedestal is 305 feet, and this is 153 more than the height of the statue. So, you can write the equation as:

Total Height = Statue Height + Pedestal Height

305 feet = h + 153 feet

Now, to find the height "h" of the statue, you can isolate it on one side of the equation. To do that, subtract 153 feet from both sides of the equation:

305 feet - 153 feet = h

152 feet = h

So, the height of the statue is 152 feet.
