3 0

Answer:

Sides: a = 122   b = 122   c = 122

Area: T = 6444.961

Perimeter: p = 366

Semiperimeter: s = 183

Angle ∠ A = α = 60° = 1.047 rad

Angle ∠ B = β = 60° = 1.047 rad

Angle ∠ C = γ = 60° = 1.047 rad

Height: ha = 105.655

Height: hb = 105.655

Height: hc = 105.655

Median: ma = 105.655

Median: mb = 105.655

Median: mc = 105.655

Inradius: r = 35.218

Circumradius: R = 70.437

Vertex coordinates: A[122; 0] B[0; 0] C[61; 105.655]

Centroid: CG[61; 35.218]

Coordinates of the circumscribed circle: U[61; 35.218]

Coordinates of the inscribed circle: I[61; 35.218]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 120° = 1.047 rad

∠ B' = β' = 120° = 1.047 rad

∠ C' = γ' = 120° = 1.047 rad

Nani needs to buy 8 cups of fresh pineapple for a fruit cocktail. the table shows the unit prices of pineapple at different stor
snow_lady [41]

Nani could purchase her pineapple from stores A, D, and E.

Given Information

It is given that Nani needs to purchase  8 cups of pineapple.

The unit prices of pineapple at each store is as follows,

Store A : 0.49

Store B : 0.51

Store C : 0.55

Store D : 0.48

Store E : 0.45

Amount that Nani has = $4

Reason Behind Purchasing From Either A, D, or E

Since Nani has amount of $4, she can purchase pineapple only from the stores where the total cost of 8 pineapple cups adds up to less than $4. The purchase of 8 pineapple cups at each store would be given as,

Store A : 0.49(8) = $3.92

Store B : 0.51(8) = $4.08

Store C : 0.55(8) = $4.40

Store D : 0.48(8) = $3.84

Store E : 0.45(8) = $3.60

As it can be seen, Nani can purchase from the store A, D, and E as it falls within her budget of $4.

Pls answer with real answers only thank you

Answer: 32.35 cm^2

Step by step:

Find the area of the rectangle first.

A= L • W
A= 11 • 4.2
A= 46.2 cm^2

Then find the area of the circle. The formula is A= pi (r)^2. The diameter of the circle is 4.2 cm because looking at the width of the rectangle it fits into the circle as well.

Half of the diameter is 2.1 cm which is the radius.

A= pi (r)^2
A= pi (2.1)^2
A= pi (4.41)
A= 13.85 cm^2

Then you would subtract 13.85 from 46.2 to find the shaded portion.

Hope this helps :))
