Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of pi

Answers

Answer:

18π cm²

Step-by-step explanation:

The area of the shaded region = Area of Sector

Radius, r =

The value of θ = 80°

Recall :

Area of Sector :

A = θ / 360 * πr²

A = (80 / 360) * π * 9²

A = 0.222222 * π * 81

A = 18π cm²

Use the points (1997, 13) and (2005, 22) to write the slope intercept form of an equation for the line of fit shown in the scatter plot. Round values to the nearest hundredth.

A. y=0.89x+1985.44
B. y=1.13x-2243.65
C. y=1.13x-2233.63
D. y=0.89x-1985.44

Answers

Answer: C. y=1.13x-2233.63

The slope-intercept form of an equation for the line of fit shown in the scatter plot is; C. y=1.13x-2233.63

What is the slope?

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

We can observe that the line of best fit on this scatters plot passes through points (1997, 13) and (2005, 22).

Using the slope formula,

⇒ slope = (22 - 13)/(2005 - 1997)

slope = (9)/8

Also, the slope-intercept form of an equation for the line of fit shown in the scatter plot is;

y - 13 = (9)/8(x - 1997)

y = 1.13x  -2233.63

Therefore, the slope-intercept form of an equation is y = 1.13x  -2233.63

A small measuring spoon holds 5 milliliters. How many spoons would 1 liter of liquid fill?

Answers

the answer is 200

1000 ÷ 5 = 200.
Answer: 200

===================================================

Work Shown:

1 liter = 1000 milliliters

1 spoon = 5 milliliters

200*(1 spoon) = 200*(5 milliliters)

200 spoons = 1000 milliliters

200 spoons = 1 liter

Notice how 1000/5 = 200, so that's why I multiplied both sides of the second equation by 200 to end up with what is shown above.

solve the triangle give the measure of angle G

Answers

Answer:

G = 46 degrees

Step-by-step explanation:

Here, we want to find the measure of angle G

Mathematically, as we can see, what we have is a right triangle

For a right triangle , the sum of angles is 90 degrees

Thus, if we add the two internal angles, we get 90 degrees

Hence;

44 + G = 90

G = 90-44

G = 46 degrees

How many grams are 7.00 x 1022 molecules of NaOH?

Answers

Answer:

46.5

explanation

6.022*10^23 molecules=40g.

7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g  are  7.00 x 10²²  molecules of NaOH.

What is mole?

The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of NaOH= 7.00 x 10²² atoms

Substituting the values

mole=7.00 x 10²²÷ 6.022×10²³

mole =0.116 moles of NaOH

mass of NaOH= Molar mass of NaOH× moles of NaOH

= 40 × 0.116

= 4.65g

Therefore, 4.65g are  7.00 x 10²²  molecules of NaOH.
