You need 3 formulas for this problem.

area of rectangle = length × width
circumference =
$2\pi \times r$
area of circle =
$\pi \times {r}^{2}$

you use circumference to find length of rectangle so you can find the area of the rectangle and the add up th e area for the rectangle and both circles for surface area

$2\pi \times 3 = 18.84$
$18.84 \times 14 = 263.76$
$\pi \times {3}^{2} = 28.26$

$sa = 263.76 + 2(28.26) = 320.28$

320.28 ÷ 3.14 = 102tt yd^2

Answer:

The percentage of the surveyed that preferred Lirt juice is 40%

Step-by-step explanation:

In this question, we are asked to calculate the percentage of beings that preferred Lirt juice

Let’s look at the survey presented in the question. 10 beings preferred out of a total of 25

The percentage that preferred Lirt juice will thus be;

10/25 * 100%

= 10 * 4 = 40%

One ordered pair (a,b) satisfies the two equations ab^4 = 384 and a^2 b^5 = 4608. What is the value of a in this ordered pair?

Alekssandra [29.7K]

Answer: a = 3∛2

<u>Step-by-step explanation:</u>

ab⁴ = 384 --> a = 384/b⁴

Substitute a = 384/b⁴ into the second equation to solve for "b".

a²b⁵ = 4608

$\bigg(\dfrac{384}{b^4}\bigg)^2\cdot b^5=4608\\\\\\\dfrac{147,456b^5}{b^8}=4608\\\\\\\dfrac{147,456}{b^3}=4608\\\\\\\dfrac{147,456}{4608}=b^3\\\\\\32=b^3\\\\\\\sqrt[3]{32} =b\\\\\\2\sqrt[3]{4} =b$
