First calculate price per gram (J) of both jars.

Large jar: J_L=\dfrac{440\mathrm{g}}{1.54\mathrm{£}}\approx 285.71 \mathrm{\frac{g}{£}}

Small jar: J_S=\dfrac{340\mathrm{g}}{1.26\mathrm{£}}\approx 269.84\mathrm{\frac{g}{£}}

Because J_S < J_L we can conclude J_S has best value.

Hope this helps.

Solve the inequality. 6x + 3 &gt; 3x + 30 A) x &gt; 9 B) x &gt; 11 C) x &gt; −9 D) x &gt; −11
ANTONII [103]

Subtract 33 from both sides

6x>3x+30-36x>3x+30−3

 Simplify 3x+30-33x+30−3 to 3x+273x+27

6x>3x+276x>3x+27

 Subtract 3x3x from both sides

6x-3x>276x−3x>27

Simplify 6x-3x6x−3x to 3x3x

3x>273x>27

Divide both sides by 3

3x>\frac{27}{3}x>

​

3x> ​27

Simplify \frac{27}{3}

Answer:

3a. ⇒ 2700 cm³

3b. ⇒ 72,900 cm³

3c. ⇒ 27

Step-by-step explanation:

3a.

∵ The model in a shape of square pyramid

∴ Its volume = base area × height

∵ Base shaped square with side length 15 cm

∴ Area of base = 15 × 15 = 225 cm²

∵ The model height = 12 cm

∴ She needs = 225 × 12 = 2,700 cm³ of plaster

3b.

∵ Each dimension in the actual stage = 3 times the model

∴ The side of the square base = 15 × 3 = 45 cm

∴ The height = 12 × 3 = 36 cm

∴ The area of the base = 45 × 45 = 2,025 cm²

∴ She needs = 2025 × 36 = 72,900 cm³ of plaster

3c.

∵ Each length in the actual stage is 3 times the model

∴ The volume of the actual stage = (3)³ the volume of the model

∴ The volume of the actual stage = 27 the volume of the model

<em>To check your answer:</em>

Volume actual ÷ Volume model = 72,900 ÷ 2700 = 27
