Hi there! I can help you! To solve this question, we can write and solve a proportion. Candida ran 100 yards in 12.7 seconds and the timekeeper ran 100 yards in 11.4 seconds. Let's start with Candida.  We could solve this by setting up the proportion to make it look like this: 100/12.7 = 220/x. You do this, because we're looking for the amount of time it would take for Candida to run 220 yards. Le'ts cross multiply the values. When you do that, you get 2,794 = 100x. Now, divide each side by 100 to isolate the "x". When you do, you get x = 27.94. x = 27.94. We found Candida's time. Now, let's look for the other person's time. Set up a proportion again. 100/11.4 = 220/x. We are looking for the other person's time. Repeat the steps. Cross multiply the values in order to get 2,508 = 100x. Now, divide each side by 100 to isolate the "x". When you do, you get 25.08. x = 25.08. We found the other person's time. Here are the answers easier to read.

Amount of time to run 220 yards

Candida: 27.94 seconds
Other person's time: 25.08 seconds

Find the output, k, when the input, t, is 3 for k(t)=10t−2. k(3)=
Papessa [141]

The value of the function k(t) for the t = 3 will be 28.

<h3>What is a function?</h3>

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given the function,

k(t)=10t−2.

Now t = 3

k(3) = 10(3) - 2

k(3) = 30 - 2

k(3) = 28

Hence "The value of the function k(t) for the t = 3 will be 28".

Consider a family that generates 20 loads of laundry in a week. based on the data in the table, what is the total number of peop
liq [111]

The total number of people in the family that generates 20 loads of laundry in a week is 10.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the number of people and x represent the number of laundry loads.

From the table:

y = (1/2)x

For 20 loads:

y = (1/2) * 20 = 10

The total number of people in the family that generates 20 loads of laundry in a week is 10.

The equation for the circle below is x^2+y^2=4. what is the length of the circle’s radius
Inessa05 [86]
2 because in the equation of a circle it is x^2 + y^2 = r^2, r=radius so you would take the square root of 4, leaving the radius of the circle to be 2.
