3^2 + (7 - 2)(4) - 6/3

= 9 + (7 - 2)(4) - 6/3

= 9 + (5)(4) - 6/3

= 9 + 20 - 6/3

= 29 - 6/3

= 29 - 2

Answer: 27

Hope that helps!!!! (Answer: Letter Choice, (B3), 27

Follow PEMDAS. So, first the ( ) needs to be done first. So that now gives us

3^2 + 5 x 4 - 6/3. Next is exponents. So now we have 9 + 5 x 4 -6/3. Next we have to do multiplication. So now we have 9 + 20 - 6/3. Now we have to add. 29-6/3. 29-2 is 27. So, 27 is the answer.

What is 5.8×10^6 mg/s in grams per minute? A. 9.7×10^9 g/min B. 9.7 × 10^7 g/min C. 3.48 × 10^5 g/min D. 3.48 × 10^3 g/min.

Luda [366]

1 second = 5.8x10^6 mg
60 seconds = 5.8x10^6 x 60 = 3.48x10^8 mg
(i.e 3.48x10^8 mg/minute)

1000 mg = 1 g
3.48x10^8 mg = 3.48x10^8/1000 = 3.48x10^5 g

Therefore, 5.8x10^6 mg/s = 3.48x10^5 g/min

6. A sector of a circle is a region bound by an arc and the two radii that share the arc's endpoints. Suppose you have a dartboa

Aliun [14]

Given the dartboard of diameter $20in$ , divided into 20 congruent sectors,

The central angle is $18^\circ$

The fraction of a circle taken up by one sector is $\frac{1}{20}$

The area of one sector is $15.7in^2$ to the nearest tenth

The area of a circle is given by the formula

$A=\pi r^2$

A sector of a circle is a fraction of a circle. The fraction is given by $\frac{\theta}{360^\circ}$ . Where $\theta$ is the angle subtended by the sector at the center of the circle.

The formula for computing the area of a sector, given the angle at the center is

$A_s=\dfrac{\theta}{360^\circ}\times \pi r^2$

<h3>Given information</h3>

We given a circle (the dartboard) with diameter of $20in$ , divided into 20 equal(or, congruent) sectors

<h3>Part I: Finding the central angle</h3>

To find the central angle, divide $360^\circ$ by the number of sectors. Let $\alpha$ denote the central angle, then

$\alpha=\dfrac{360^\circ}{20}\\\\\alpha=18^\circ$

<h3>Part II: Find the fraction of the circle that one sector takes</h3>

The fraction of the circle that one sector takes up is found by dividing the angle a sector takes up by $360^\circ$ . The angle has already been computed in Part I (the central angle, $\alpha$ ). The fraction is

$f=\dfrac{\alpha}{360^\circ}\\\\f=\dfrac{18^\circ}{360^\circ}=\dfrac{1}{20}$

<h3>Part III: Find the area of one sector to the nearest tenth</h3>

The area of one sector can be gotten by multiplying the fraction gotten from Part II, with the area formula. That is

$A_s=f\times \pi r^2\\=\dfrac{1}{20}\times3.14\times\left(\dfrac{20}{2}\right)^2\\\\=\dfrac{1}{20}\times3.14\times10^2=15.7in^2$

The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

<h3>How to determine the rock's height?</h3>

The function is given as:

d = √216 +h²

At a distance of 100 feet, it means that:

d = 100

So, we have:

√216 +h² = 100

Take the square of both sides

216 +h² = 10000

Subtract 216 from both sides

h²= 9784

Take the square root of both sides

h = 98.9

Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
