Answer:

1733.28 in^2.

Step-by-step explanation:

The radius r = 1/2 the diameter = 1/2 *12 = 6 inches.

SA = 2*3.14*6^2 + 2*3.14*6*40

= 1733.28 in^2.

The circumference of a circle is given by the formula C=2πr. Find r if the circumference is 396 meters and π is 22/7.
larisa86 [58]

Answer:

r = 63 meters

Step-by-step explanation:

C=2πr

We know pi and C

396 =  2*22/7*r

396 = 44/7 *r

Multiply each side by 7/44 to isolate r

396*7/44 = 7/44 *44/7 *r

63 =r

(10 POINTS AND BRAINLIEST)
bekas [8.4K]

Answer:

A.) 15.60=11.40+10x

Step-by-step explanation:

okay we know kathy spent 15.60 in total at the post office

so we know 15.60 will be after the equal sign.

she paid 11.40 only on the package

and rest of money was on stamps.

15.60-11.40= 4.20

so she used 4 dollars and 20 cents for stamps if she bought 10 we need to divied 4.20/10=0.42

0.42 cents for each stamps so we need a equation that will give us this answer.

Me i go thru each one and solve for x

lucky for me i just need to solve one

because equation A solves it correctly.

15.60=11.40+10x

subtract 11.40 on both sides

15.60-11.40

4.20=10x

now we divide 10 on each side

4.20/10=0.42

x=0.42

I NEED HELP PLS!!!!
hram777 [196]

Answer:

15

Step-by-step explanation:

For these kind of problems, its best to use a Venn Diagram.

Lets break down the information:

<em>There are 50 students total.</em>

<em>25 take Math competiton classes.</em>

<em>29 take Geometry</em>

<em>12 take history and </em><em><u>no math classes</u></em>

<em>19 take </em><em><u>both math classes</u></em>

Now, make a Venn Diagram.

[Look at the photo attached. Also, the blank spaces in the Venn Diagram are ones that no student takes.]

The 12 taking history and no math classes and 3 kids not taking any of those classes look like they're the only ones not taking either math class.

12 + 3 = 15.

So the answer is 15.

[I'm not sure if this is correct or if I made a mistake so please let me know! Thank you! I hope this helps!]

Write an equation of a line that passes through (-6, 1), parallel to y = 2x – 6.
Eddi Din [679]

Answer:

y = -1/2x - 2

Step-by-step explanation:

If it's parallel, that means that the slope is the opposite of the one in the given equation, meaning that 2 would be flipped and turned negative into -1/2.

Then, fill in the x and y values to get the y-intercept.

1 = -1/2(-6) + b

1 = 3 + b

-2 = b

So your answer is y = -1/2x - 2
