Answer:

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

x^2 + y^2 = 16

can be rewritten as

(x-0)^2 + (y-0)^2 = 4^2

Where the center is (0,0) and the radius is 4

A clown bought 5 bags of round balloons with 24 balloons in each bag. The clown also bought 3 bags of long balloons with 36 ball

dimaraw [331]

Answer:

247 blown up balloon left

Step-by-step explanation:

5 bags of round balloon with 24 balloon in each bag =

= 5 x 24 = 120 round balloons

3 bags of long balloon with 36 balloon in each bag =

= 3 x 36 = 108 long balloons

Part 1 Answer

120 round balloons - 108 long balloon = 12 balloons

therefore the clown bought 12 more round balloon than long balloon

Part 2

3 bags of heart-shaped balloons with 14 balloons in each bag =

= 3 x 14= 42 heart-shaped balloons

All the balloons were blown which equals

120 round balloons + 108 long balloons + 42 heart-shaped balloons =

= 270 balloons

23 balloons out of the 270 balloons burst which equals

270 blown balloon - 23 burst balloon = 247 blown-up balloons left

so,

247 blown-up balloons were left

Answer:

h = 10.92 m.

Step-by-step explanation:

The small triangle on the left is similar to the whole triangle, so:

12/20 = h/18.2

h = 12*18.2 / 20

h = 10.92 m.

∠2 = ∠3 | Given

∠1 + ∠2 = 180 | Supplementary Angles Postule (If two angles are adjacent and ∠3 + ∠4 = 180| linear, they're supplementary)

∠1 + ∠2 = ∠3 + ∠4 | Transitive property

∠1 + ∠3 = ∠3 + ∠4 | Substitution property

∠1 = ∠4 | Subtraction Property

∠2 = ∠3 | Supplementary Congruent Theorem
