Chop it into shapes you know how to solve with:
Rectangle with dementions 6m x 3m A=18m^2
Rectangle with dementions 12m x (8-3)m A=60m^2
Rectangle with dementions 2m x 3m A=6m^2
total area= 18+60+6=84m^2

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

Answer:
equivilent to what?
Step-by-step explanation:
A small measuring spoon holds 5 milliliters. How many spoons would 1 liter of liquid fill?
===================================================
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
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?
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.

Step-by-step explanation:
Here is a scatter plot that compares points per game to free throw attempts per game for basketball players in a tournament. The model, represented by y=4.413x+0.377, is graphed with the scatter plot. Here, x represents free throw attempts per game, and y represents points per game.
What does it mean for a point to be far above the line in this situation?
Answer:
Point above the line is an outlier
Step-by-step explanation:
If the point is above the given line then it is clear that it does not fit the best fit curve (which is in this case is the line represented by equation y=4.413x+0.377)
Point above this line means that the point is an outlier which does not fit the curve.
