2. You are creating a cone-shaped hat for a kid’s costume. You measure the circumference of the child’s head and find it to be 2

0.5 inches.
A. Determine the radius of the hat.

B. You want the hat to have a slant height of 8 inches. Draw an image that models this situation and include all of the measurements you know.

C. How much material would you need to make the hat? Your answer should be in square inches.


3. For this question, we will find the surface area of a cylinder, using an object from your kitchen.

A. Locate a canned good from your kitchen. Some examples include a can of soup, a can of vegetables, or a can of fruit. Describe the type of can that you are using.

B. Draw a picture of your canned good. Measure the height of the can and the diameter of the top surface. Label the measurements on your picture.

C. Calculate the surface area of the canned good. Show all of your work. Round your answer to the nearest whole number.

Just draw a triangle(front view) and the slant/inclined sides of it are known to be 8 and you found out radius as 3.26. so mark the diameter by doubling radius.

so the material required would be a slice(like pizza slice) of a circle of radius= 8 and arc length = circumference given ,that is 20.5

now using this find the area of sector/slice. its the answer to the last bit.

now coming to next question, go to the kitchen and take any can and measure its dia and height by using a scale. and you might already know the formula to find the suface area of cylinder.

Please order -4 1/2,5.6,-2 3/8, and 1.35
ExtremeBDS [4]
-4 1/2 = -4.5

5.6 = 5.6

-2 3/8 = -2.375

1.35 = 1.35

If we order it from least to greatest, we would get:
-4 1/2, -2 3/8, 1.35, 5.6

If we order it from greatest to least, we would get:
5,6, 1.35, -2 3/8, -4 1/2

What is the awnser to the circled equations?​
pshichka [43]

Answer:

y = - \frac{1}{3}x - 1

Step-by-step explanation:

We have to write an equation of a line which  passes through the given point (-9,2) and is perpendicular to the given straight line y = 3x - 12 ........... (1)

Now, equation (1) is in the slope-intercept form and the slope of the line is 3.

Let, m is the slope of the required line.

So, 3m = -1

{Since, the product of the slopes of two perpendicular straight lines is -1}

⇒ m = - \frac{1}{3}

Therefore, the equation of the required line in slope intercept form is  

y = - \frac{1}{3} x + c {Where c is a constant}

Now, this above equation passes through the point (-9,2) point.

So, 2 = -  \frac{1}{3} \times (-9) + c

⇒ 2 = 3 + c

⇒ c = - 1  

Therefore, the equation of the required straight line is y = - \frac{1}{3}x - 1 (Answer)

FOR BRAINLIST ANSWER AND 10 POINTS ANSWER ALL PLZ !!!!!
igor_vitrenko [27]
<h2>Greetings!</h2>

A)

<h3>If you can see, every 4 minutes the amount of water is increasing at a constant rate. </h3>

197 - 153 = 44

285 - 241 = 44

<h3>This means that at 8 minutes, because there is 153 gallons already in, we can divide 8 by 4 to see how many groups of 4 minutes there were. </h3>

8 ÷ 4 = 2

So then we can subtract two lots of 44 from 153:

153 - (44 x 2) = 65

<h3>So the starting amount was 65.</h3>

B)

<h3>The answer to B is the second option, because it is true that the amount of water is increasing. This is by 44 gallons per 4 minutes.</h3>

The amount of gallons per minute can be found out by dividing the amount by 4:

44 ÷ 4 = 11

<h3>So it is 11 gallons per minute.</h3>
<h2>Hope this helps!</h2>
