Ymorist [56]

The draw an inscribed polygon inside the circle, the very thing to do is to draw the circle. Thus, the answer is the fourth choice, "Place a point on your paper and then use a compass to construct a circle". After which, we can locate the vertices of the polygon in the circumference of the circle and connect them to make the polygon.

Carl is on the school track team. To prepare for an upcoming race, he plans to run 217 miles total over the next 31 days. Write

Aloiza [94]

Answer:

m=217 miles/31 days

Step-by-step explanation:

Carl has to run 217 miles in 31 days; to find the number of miles $m$ he needs to run per day, he should divide the number of miles he has to run (217 miles ) by the number to days he will run ( 31 days):

$m=217\:miles/31\:days =7\:miles/day$

$\boxed{7\:miles/day}$

Carl has to run 7 miles per day. We can confirm this result by multiplying this by 31 days, and we should get 217 miles:

$(7miles/day)*31days=217 miles.$

Find the measure of each of the angles. Don’t forget to label your answer

user100 [1]

Answer:

$a=125^o$

$b=55^o$

$c=55^o$

$d=55^o$

$e=125^o$

$f=55^o$

Step-by-step explanation:

step 1

Find the value of x

we know that

$(2x+25)^o=(x+75)^o$ ----> by alternate interior angles

solve for x

Group terms

$2x-x=75-25$

$x=50$

step 2

Find the measure of angle a

we know that

$a=(x+75)^o$ ----> by vertical angles

substitute the value of x

$a=(50+75)=125^o$

step 3

Find the measure of angle b

we know that

$a+b=180^o$ ----> by supplementary angles (form a linear pair)

we have

$a=125^o$

substitute

$125^o+b=180^o$

$b=180^o-125^o=55^o$

step 4

Find the measure of angle c

we know that

$c=b$ ----> by vertical angles

we have

$b=55^o$

therefore

$c=55^o$

step 5

Find the measure of angle d

we know that

$d=b$ ----> by corresponding angles

we have

$b=55^o$

therefore

$d=55^o$

step 6

Find the measure of angle e

we know that

$e=a$ ----> by alternate exterior angles

we have

$a=125^o$

therefore

$e=125^o$

step 7

Find the measure of angle f

we know that

$f=d$ ----> by vertical angles

we have

$d=55^o$

therefore

$f=55^o$

The mean absolute deviation,like where do I take it from?

timofeeve [1]

So Mean Absolute Deviation or MAD for short is the Mean of how far each digit is from the Mean. So first find the mean, then for each number so let's say the mean is 3 and the numbers are 2, 4, 3. So 3-2=1, 4-3=1, 3-3=0. So you have 1, 1, 0. Find the mean of that 1+1+0=2/3 so the MAD is 2/3.

So just follow my steps
1. Find the mean
2. Find the difference from the mean of each number
3. Find the mean of step 2
4. Step 3 is your answer

64 divided by 0.4 and explain how you did it please i don't wanna be stuck on this all night

Brrunno [24]

Okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.

so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.

so if you have
64 4
---- / ----
1 10

you would switch the 2nd one so the 10 would be on top.

so that would give you 64*10 over 1*4

which equals 640/4

& when you simplify that you get 160

so that's your answer(:
