Answer:

180 cm

Step-by-step explanation:

I had to look up some of these equations

Central angle  'a' = 2 arcsin ( c/(2R) = 2 arcsin (120/(2*100) ) = 73.74°

d= R cos ( a/2) = 100 cos ( 73.74/2) = 80 cm

So from the cutout to the bottom will be   80 + 100 = 180 cm

Jogging, cycling, swimming, aerobics, rowing, stair climbing, and sports-related games are examples of cardiovascular fitness. For Body composition, the push-up is the best example.

During a physical activity like running, jogging, or doing workouts involving cardiovascular activities, the circulatory and respiratory systems of the body provide oxygen to the skeletal muscles. When oxygen reaches the muscles, the risk of cardiovascular disease is decreased.

Also, the body is able to do larger muscle exercises due to increased flexibility, and the efficiency of the respiratory system also increases. But more blood is pumped through the body due to cardiorespiratory activities is not the benefit of doing physical activities.

Simple interest shows the amount of money an account earns based on the initial deposit.

Interest Formula

The formula to find the amount of interest earned is I = Prt. In this equation, I is the total interest earned, P is the principal or the initial deposit, r is the interest rate as a decimal, and t is the time in years.

To find the total balance of the account just add the interest amount to the principal. So, A = I + P, where A is the total balance.

Solving for Simple Interest

For this question, the variables are:

Now, we can plug these values into our formula.

After 4 years, the account will earn $93.60 in simple interest.

The required distance between the points J and K is given as D = √113.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here,
Two points, J and K have the coordinates (6,-2). and K (6,-9).
Distance between the point is given by the distance formula.
D = √[[x₂ - x₁]² + [y₂+ - y₁]²]
D = √{6 + 2}² + {-9 + 2}²
D= √64+ 49

In the function f(x) = a(b^x), the initial value is always a because a is independent on x. So, when x changes, b^x will change as well but a will remain the same.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. A function is an equation with a single solution for y for each value of x. A function pairs each input of a particular type with exactly one output.

For example, let a = 2, b = 3, and x = 0: f(0) = 2 3^0 = 2 1. If x = 1, then f(1) = 2 3^1 = 2 3. If x = 2, then f(2) = 2 3^2 = 2 9, etc. As you can notice a = 2 remain unchanged as the initial value, because a is independent on x change.

The inverse additive of 2 3 is -2 3.. This means that when you add the two numbers together, the result is 0.

2 3 + (-2 3)

= (2 x -1) + (3 x -1)

= -2 + (-3)

= -5

= 0

The additive inverse of 2 3 is -2 3. In mathematics, an additive inverse is a number that when added to another number will produce a result of zero. This means that when you add 2 3 and -2 3 together, the result will be 0. To calculate this, we first start by multiplying each number by its opposite sign. So,

2 x -1 = -2 and

3 x -1 = -3.

Then, we add the two numbers together

: -2 + (-3) = -5.

Answer:

Takes maria

Step-by-step explanation

Maria's rate of speed is 46.5 kilometers per hour.

What is the distance?

Distance is defined as the product of speed and time.

Since there are 3600 seconds in an hour, we can divide the time it takes Gretchen to travel 4400 meters by 3600 to find the number of hours it takes her:

⇒ 340 seconds / 3600 seconds/hour = 0.09444444 hours.

Next, we need to convert the distance she travels to kilometers. Since there are 1000 meters in a kilometer, we can divide the distance Maria travels by 1000 to find the number of kilometers she travels:

⇒ 4400 meters / 1000 meters/kilometer = 4.4 kilometers.

Now that we have the distance Maria travels and the time it takes her to travel that distance in the appropriate units, we can divide the distance by the time to find her rate of speed in kilometers per hour:

⇒ 4.4 kilometers / 0.09444 hours = 46.5882375  kilometers/hour.

Thus, Maria's rate of speed is 46.6 kilometers per hour.

Since the speed of the bus is given in miles per hour (mph) and we want to know the distance covered in minutes, we need to convert the time to minutes. Therefore, distance = speed x (time in minutes / 60).

b) To determine the distance covered by a bus traveling at sodi mph for 3 hours, we can use the formula: distance = speed x time.

distance = sodi x 3

c) To determine the distance covered by a bus traveling at sodi mph for 30 minutes, we need to convert 30 minutes to hours. Therefore, time = 30/60 = 0.5 hours.

The selling price of the washer/dryer is $1,137.86. Thus, the correct answer is option b.

To find the cost of the washer/dryer, we need to reverse the markup percentage. We can do this by dividing the markup by 100 and then multiplying by the selling price.

Markup = (Markup Percentage) x (Cost)

So, if we rearrange this equation and solve for cost:

Cost = (Markup) / (Markup Percentage)

Plugging in the given information:

Cost = $295.00 / 0.35

Cost = $842.86

To find the selling price, we add the markup to the cost:

Selling Price = Cost + Markup
