The Answer:

2.4x10=24

there is one 0 in 10, so you move the decimal over by 1, resulting in 2.4 turning into 24

Answer:

Step-by-step explanation:

$2.4\times\:10\\$

Multiply without the decimal points then put the decimal point in the answer

$24\times\:10=240\\$

2.4 has 1 decimal place

10 has 0 decimal places

Therefore, the answer has 1 decimal place

$\\=24.0\\\\=24$

The measure of a central angle in degrees is 11.25°.

<h3>How to get the values?</h3>

The name of the Ferris wheel is London eye

The diameter of the wheel (in meters) is 394

The number of cars or compartments 32

The circumference of the wheel (in meters) 394*pi=1237.78

The area of the wheel (in meters)394/2=197 a=pi*197^2=618.58

The measure of a central angle in degrees will be:

= 360°/Number of the compartment

= 360°/32

= 11.25°

The measure of a central angle in radians will be:

= 2π/Number of compartment

= 2π/32

= π/16 radians

The arc length between two cars or compartments will be:

= π/16 × (394/2)

= π/16 × 197

= 197π/16

= 38.69m

The area of a sector between two cars or compartments will be:

= central angle/360° × π × radius ²

= 11.25/360 × 3.142 × (394/2)²

= 3810.56m²

The area of an Equilateral triangle is given by the formula A= 3pi squared/4(s)Squared. Which formula represents the length of e

ad-work [718]

Answer:

The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is $\text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$ .

Step-by-step explanation:

We are given the area of an Equilateral triangle which is A = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$ . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

So, the area of an equilateral triangle = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$

where, s = side of an equilateral triangle

A = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$

Cross multiplying the fractions we get;

$4 \times A = \sqrt{3} \times \text{s}^{2}$

$\sqrt{3} \times \text{s}^{2}= 4\text{A}$

Now. moving $\sqrt{3}$ to the right side of the equation;

$\text{s}^{2}= \frac{4 \text{A}}{\sqrt{3} }$

Taking square root both sides we get;

$\sqrt{\text{s}^{2}} = \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$

$\text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$

Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

Yul has lunch at a restaurant. If his bill was $14.50 and Yul wants to leave a 20% tip, what is the amount he should leave for t

slamgirl [31]

Answer: $2.90

Step-by-step explanation: So you get 10% if you just move the decimal one place to the left so that would be 10%= 1.45 and then you mutiply that by 2 since 10% times 2 is 20% and that is your answer
