o=4i (is that was you were asking about)

edit: sorry that wasn't very detailed say if the input is 4 the output will be 16 or if the input is 100 the output will be 400. So mainly what ever the input is multiply it by 4.

Y varies directly as x. if x=5 when y=12 find x when y=30

Answers

I guess "varies directly" means that if, for example, you take x=6 you get y=13 or for x=4 y is 12.
Assuming this, you get:
$x_1 = 5 \n y_1 = 12 \n y_2 = 30 \n x_2 = ? \n \n x_2 - x_1 = y_2 - y_1 \n x_2 = x_1 + y_2 - y_1 \n x_2 = 5 + 30 - 12 \n x_2 = 23$
The logic would fit, I guess :/

Answer: The equation is y=k(x). So 12=k(5), divide by 5 on both sides coming up with k=2.4. Plug 2.4 in as k in the original equation, making it 30=2.4(x), divide both sides by 2.4, 30 divided by 2.4 is 12.5, making x=12.5

Step-by-step explanation:

the areas of the two watch faces have a ratio of 16:25. what is the ratio of the radius of the smaller watch face to the radius of the larger watch face?

Answers

The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

What is the area of the circle?

The area of the circle is given by the formula,

$\text{Area of the Circle} = \pi r^2$

As we know that the ratio of the area of the two watches is 16:25. And we also know that the area of a circle is given by the formula,

$\text{Area of the Circle} = \pi r^2$

Now, as we know that the ratio of the area of the watches can be written as,

$\frac{\text{Area of the small watch face}}{\text{Area of the Large watch face}} = (16)/(25)\n\n(\pi r^2)/(\pi R^2) =(16)/(25)\n\n(r^2)/(R^2) = (16)/(25)\n\n(r)/(R) = \sqrt{(16)/(25)}\n(r)/(R) = (4)/(5)$

Hence, the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

Answer:

4:5

Step-by-step explanation:

Let r be the radius of small watch

Area of small watch=π $r^(2)$

Let R be radius of larger watch= π $R^(2)$

Area of larger watch= π $R^(2)$

It is given that the ratio of their areas= 16:25

$( Area of smaller circe)/(Area of larger circle)$ = $(16)/(25)$

π $r^(2)$ : π $R^(2)$ = 16:25

$(r)/(R)$ = $(√(16) )/(√(25) )$

r:R= 4:5

Hence, the ratio of their radii= 4:5

Hence, the correct answer is 4:5

Compare rates of change.A. The equation below can be used to find the length of a foot or forearm when you know one or the other.

(length of the foot) = 0.860 • (length of the forearm) + 3.302

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.

Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

B. What is the rate of change of the equation from Part A?

Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?

C. Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.

Answers

y=foot
x=foram

A. easy, plug 17 for x and evaluage for y
y=0.860(17)+3.302
y=14.62+3.302
y=17.922 inches

B. rate of change is slope
y=mx+b
m=slope
so
rate or change is 0.860 inches per legnth of forarm

C. what data

D. it is a function
since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line
it is a function

Step-by-step explanation:

Part A:

y=0.860x + 3.302

y= 0.860(17) + 3.302

y= 14.62 + 3.302

y= 17.922

Part B:

step 1

y=0.860x + 3.302

y= 0.860(17) + 3.302

y= 14.62 + 3.302

y= 17.922

step 2

y=0.860x + 3.302

y= 0.860(18) + 3.302

y= 15.48 + 3.302

y= 18.782

step 3

18.782-17.922=.86

So, the rate of change is .86

Antonio makes only one size latte, and he uses 1/3 cup of milk to make each drink. How many lattes can he make with 5/6 of a cup

Answers

Because one drink is 1/3 of a cup, or 2/6, you simply find out how many times 2/6 can go into 5/6. Because 5/6 divided by 2/6 is 2 remainder 1/6, antonio can make 2 full lattes with 1/6 cup remaining, or half a latte.
