Question 15 (1 point)

zloy xaker [14]

Answer:

The value of k is 12.57
Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3

Step-by-step explanation:

Let s be the surface area and r be the radius

Then according to given statement

s∝r²

Removing the proportionality symbol introduces k, the constant of proportionality

$s = kr^2$

Now

A soap bubble with a 0.75 in. radius has a surface area of approximately 7.07 square inches.

Putting in the equation

$7.07 = k (0.75)^2\\7.07 = k * 0.5625\\k = \frac{7.07}{0.5625}\\k = 12.5688..\\k = 12.57$

The euqation beomes

$s = 12.57r^2$

Putting s = 113.1 in the equation

$113.1 = 12.57r^2\\r^2 = \frac{113.1}{12.57}\\r^2 = 8.99761...\\\sqrt{r^2} = \sqrt{8.9976..}\\r = 2.9996..$

Hence,

The value of k is 12.57
Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3

Ms. Ibarra has 15 less hats than 7 times Ms.boyle. Find the correct expression for Ms. Ibarra

dlinn [17]

The correct expression for hats with Ms. Ibarra is a = 7b - 15 where "a" represents number of hats with Ms. Ibarra and "b" represents number of hats with Ms.boyle

<h3><u>Solution:</u></h3>

Given that Ms. Ibarra has 15 less hats than 7 times Ms. boyle

To find: correct expression for Ms. Ibarra

Let the number of hats with Ms. Ibarra be "a"

Let the number of hats with Ms.boyle be "b"

Ms. Ibarra has 15 less hats than 7 times Ms. boyle Which means,

Number of hats with Ms. Ibarra = 7(number of hats with Ms.boyle) - 15

a = 7(b) - 15

a = 7b - 15

So the correct expression for hats with Ms. Ibarra is a = 7b - 15
