Answer:
When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative
Solve for the value of a.
Answer:
a=11
Step-by-step explanation:
So, the line that (9a+6) and 75 are sharing is straight, meaning that it is 180 degrees. Also, (9a+6) and 75 are sharing the line. Even though we don't know there exact measurements, when know that by adding them together we will get 180 degrees.
1. (9a+6) + 75 = 180
2. 9a + 81 = 180
3. 9a = 99
4. a = 11

what is the distance rounded to the nearest tenth between the points (2 -2) and (6 3)
Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Substituting the known 'x', and 'y', values for the coordinates of the points, we have;
[tex]l_{(2, \, -2), \ (6, \, 3) } = \sqrt{\left (3-(-2) \right )^{2}+\left (6-2 \right )^{2}} = \sqrt{5^2 + 4^2} = \sqrt{41}[/tex]
Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.

Answer:
Hope it helps u
Step-by-step explanation:
When rotating a point 270 degrees counterclockwise about the origin our point A(x, y) becomes A'(y,-x). This means, we switch x and y and make x negative,
hence A(2,1) so after 270 degree counter clockwise rotation the A become,
A(1, -2)

N2 + 3H2 → 2NH3
How many moles of NH3 could you make with 4.2021 g of N2?
2. 2Na + Cl2 → 2NaCl
How many moles of Cl2 do you need to use in order to react with 34.485 g of Na?
3. H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4
How many grams of NaNO2 do you need in order to make 24.14714 g of Na2SO4?
4. 2Na + 2H2O → 2NaOH + H2
How many grams of NaOH could you make with 8.0465 g of Na?
5. 2Mg + O2 → 2MgO
If you are burning 5.8332 g of Mg, how many grams of MgO will this make?
6. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
How many grams of NaCl could you make with 2.43306 g of FeCl3?
Step-by-step explanation:
1. N2 + 3H2 → 2NH3
How many moles of NH3 could you make with 4.2021 g of N2?
From the reaction;
1 mol of N2 produces 2 mol of NH3
1 mol of N2 = 14g of N2
14g of N2 produces 2 mol of NH3
4.2021 g of N2 produces x mol of NH3
14 = 2
4.2021 = x
x = 4.2021 * 2 / 14 = 0.6003 mol of NH3
2. 2Na + Cl2 → 2NaCl
How many moles of Cl2 do you need to use in order to react with 34.485 g of Na?
From the equation of the reaction;
2 mol of Na reacts with 1 mol of Cl2
1 mol of Na = 23g of Na
2 mol of Na - 46g of Na
46g of Na reacts with 1 mol of Cl2
4.485 g of Na reacts with x mol of Cl2
46 = 1
4.485 = x
x = 4.485 * 1 / 46 = 0.0975 mol of Cl2
3. H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4
How many grams of NaNO2 do you need in order to make 24.14714 g of Na2SO4?
From the reaction;
2 mol of NaNO2 produces 1 mol of Na2SO4
2 mol of NaNO2 = 68.995 g/mol * 2mol = 137.99g
1 mol of Na2SO4 = 142.04 g
137.99g of NaNO2 produces 142.04 g of Na2SO4
xg of NaNO2 produces 24.14714 g of Na2SO4?
137.99 = 142.04
x = 24.14714
x = 24.14714 * 137.99 / 142.04 = 23.459g
4. 2Na + 2H2O → 2NaOH + H2
How many grams of NaOH could you make with 8.0465 g of Na?
From the reaction;
2 mol of Na produces 2 mol of NaOH
2 mol of Na = 23g/mol * 2mol = 46g
2 mol of NaOH = 40g/mol * 2 = 80g
46 g of Na produces 80g of NaOH
8.0465 g of Na produces xg of NaOH
46 = 80
8.0465 = x
x = 8.0465 * 80 / 46 = 13.994g
5. 2Mg + O2 → 2MgO
If you are burning 5.8332 g of Mg, how many grams of MgO will this make?
From the reaction;
2 mol of Mg produces 2 mol of MgO
2 mol of Mg = 24 g/mol * 2mol = 48g
2 mol of MgO = 40.3 g/mol * 2mol = 80.6g
48g of Mg produces 80.6 g of MgO
5.8332 g of Mg produces xg of MgO
48 = 80.6
5.8332 = x
x = 5.8332 * 80.6 / 48 = 9.8g
6. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
How many grams of NaCl could you make with 2.43306 g of FeCl3?
From the reaction;
1 mol of FeCl3 produces 3 mol of NaCl
1 mol of FeCl3 = 162.2 g
3 mol of NaCl = 58.44 g/mol * 3 mol = 175.32 g
162.2g of FeCl3 produces 175.32 g of NaCl
2.43306 g of FeCl3 produces xg of NaCl
162.2 = 175.32
2.43306 = x
x = 2.43306 * 175.32 / 162.2 = 2.63g
Eiman borrowed $8000 at a rate of 14.5%, compounded semiannually. Assuming she makes no payments,
how much will she owe after 6 years?
Do not round any intermediate computations, and round your answer to the nearest cent.?
Answer:
1,717,351cents
Step-by-step explanation:
Using the compound interest formula
A = P(1+r/n)^nt
P = 8000
r = 14.5% = 0.145
n = 6/12 = 1/2 (semi annually)
t = 6years
Substitute
A = 8000(1+ 0.145/0.5)*(0.5)(6)
A = 8000(1+0.29)^3
A = 8000(1.9)^3
A = 8000(2.146689
A = 17,173.512
Hence the amount owned to the nearest cent is 1,717,351cents

Answer: y= 8295
Step-by-step explanation:
Which equation represents a linear function?
A) x = y2
B) y – 2 = x2 + 5x
C) y = x3 + 1
D) 5x + 6y = 12
Answer:
D) 5x + 6y = 12
Step-by-step explanation:
x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)
y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)
y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)
Find the measure of the exterior angle in the following triangle. DUE SOON PLZ HELP WITH STEP BY STEP
Answer:
The measure of an exterior angle = 125°
Hence, option A is correct.
Step-by-step explanation:
As the given triangle is a right-angled triangle ΔABC.
Given the angles
m∠A = 35°m∠C = 90°We know that the sum of angles in a triangle is 180°.
Thus,
m∠A + m∠B + m∠C = 180°
substituting m∠A = 35° and m∠C = 90° in the equation
35° + m∠B + 90° = 180°
125 + m∠B = 180°
subtract 125 from both sides
125 + m∠B - 125 = 180° - 125
m∠B = 55°
Thus, the measure of angle B is:
m∠B = 55°
As the exterior angle of the given triangle is adjacent to m∠B = 55°.
We know that the exterior angle of a triangle is equal to the sum of two opposite interior angles.
Here,
∠A and ∠C are two opposite interior angles of the exterior angle.
Thus,
The measure of an exterior angle is equal to the sum of two opposite interior angles.
as
m∠A = 35°m∠C = 90°so
Exterior angle = m∠A + m∠C
= 35° + 90°
= 125°
Thus, the measure of an exterior angle = 125°
Hence, option A is correct.
Suppose a city with population 600,000 has been growing at a rate of 4% per year. If this rate continues, find the population of this city in 15 years
Answer:
360,000
Step-by-step explanation:
Alright so first we need to find 4% of 600,000
So we get 24,000 now we multiply this by 15
24,000 x 15 = 360,000

THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT
Answer:
259.09 feet
Step-by-step explanation:
Given that,
The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.
We need to find the perimeter of the lot.
We know that,
Perimeter = sum of all sides
P = 100.52 + 15.321 + 143.250
P = 259.09 feet
So, the required perimeter of the lot is 259.09 feet.
