Answer:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

Step-by-step explanation:

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc EH

Remember that the measure of the complete circle is equal to 360 degrees

$arc\ EH+arc\ EF+arc\ FG+arc\ GH=360^o$

Remember that

$arc\ EF=m\angle EDF$ ----> by central angle

$arc\ FG=m\angle FDG$ ----> by central angle

$arc\ GH=m\angle GDH$ ---> by central angle

substitute the given values

$arc\ EH+55^o+70^o+110^o=360^o$

$arc\ EH=360^o-235^o=125^o$

step 2

Which arc is congruent to Arc E H?

we know that

$arc\ EFG=arc\ EF+arc\ FG=55^o+70^o=125^o$

therefore

arc EH is congruent with arc EFG

arc EH is congruent with minor arc GE

il63 [147K]

Answer:

7 crates

Step-by-step explanation:

Let

x ----> the number of crates needed

we know that

Two crates can hold 250 boxes

using proportion

Find out how many crates they'll need for 875 boxes

$\frac{2}{250}\frac{crates}{boxes} =\frac{x}{875}\frac{crates}{boxes}\\\\x=2(875)/250\\\\x=7\ crates$

Number 21 is confusing

Oksi-84 [34.3K]

Add the cost of all the items together
5.45 for cups + 4.75 for plates + 11.50 for the punchbowl + 2(7.80) for baloons = 37.3 Then divid 37.3 by the 10 friends, and each will pay $3.73
