Answer:

2.59

Step-by-step explanation:

Simple! You must divide the number of pounds by the cost to get the price for 1 pound. Or, set up a proportional table:

7.77 = x amount of dollars

3 = 1

Or:

Divide 7.77 by 3:

7.77 / 3 =2.59.

Answer/Step-by-step explanation:

✔️Find EC using Cosine Rule:

EC² = DC² + DE² - 2*DC*DE*cos(D)

EC² = 27² + 14² - 2*27*14*cos(32)

EC² = 925 - 756*cos(32)

EC² = 283.875639

EC = √283.875639

EC = 16.85 cm

✔️Find the area of ∆DCE:

Area = ½*14*27*sin(32)

Area of ∆DCE = 100.15 cm²

✔️Since ∆DCE and ∆ABE are congruent, therefore,

Area of ∆ABE = 100.15 cm²

✔️Find the area of the sector:

Area of sector = 105/360*π*16.85²

Area = 260.16 cm² (nearest tenth)

✔️Therefore,

Area of the logo = 100.15 + 100.15 + 260.16 = 460.46 ≈ 460 cm² (to 2 S.F)

Answer:

Option D

Step-by-step explanation:

<em>If the bases are the same in a multiplication problem, then you can simply add the exponents. (i.e., a² × a⁶ = a²⁺⁶ = a⁸)</em>

$\bullet \rightarrow 5^4\times5^7$

$\bullet\rightarrow 5^{4 + 7}$

$\bullet \rightarrow \boxed{5^{11}}$
