Answer:
$12,500
Step-by-step explanation:
Given that, Linda purchased a house for $120,000 in 2007 and the value of the house was $245,000 in 2017.
Total change in the value of house= $245,000- $120,000=$125,000.
Total time (in years) between 2007 and 2017 = 2017-2007=10 years.
The value of the house changes by $125,000 in the time interval of 10 years.
So, the average annual rate of change in the value of the house = $125,000/10=$12500 per year.
Hence, the average annual rate of change in the value of the house is $12,500.

Isosceles triangle MNis shown below with MN ~= PN. Ray NQ bisects angle MNP and intersects side MP at point Q. Name three pairs of congruent angles
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are obtuse, scalene, equilateral, isosceles etc.
An isosceles triangle is a triangle with two equal sides, the base angles of an isosceles triangle is equal.
Since ΔMNP is an isosceles triangle with MN = PN, then:
∠QMN = ∠QPN (base angles of an isosceles triangle are equal)
∠MNQ = ∠PNQ (NQ bisects ∠MNP producing two equal angles)
∠MQN = ∠PQN (right angles)

Nathan earns $1500 a week. Calculate his new weekly wage if he receives a pay rise of 20%
Answer:
$1800
Step-by-step explanation:
1. Approanch
An easy way to calculate one's salary after they recive a raise is to, convert the percent that one's salary is increased into a decimal; divide the percent by 100. Then multiply the increase as a decimal by the original salary, to attain the amount the salary is raised by. Finally add the amount the salary is raised by to the original salary to find the new salary. A quicker way to do this is to convert the percent by the salary is increased into a decimal. Then add 1 to that number. Finally one will multiply that number by the original slary and get the new salary.
2. Solving
Original salary; 1500
Raise; 20%
a. convert the raise as a percent into a decimal, then add 1
20% = 0.2
0.2 + 1 = 1.2
b. multiply the number by the original salary
1.2 * 1500
1800
Answer:
$ 1800
Step-by-step explanation:
Rise in payment = 20% of 1500
[tex]= \frac{20}{100}*1500\\\\=20 *15\\\\= $300[/tex]
New weekly wage = 1500 + 300
= $ 1800

A simple off bacteria is debating according to the half life model. If the simple begins with 800 bacteria, and after 18 minutes there is 240 bacteria, after how many minutes will there be 40 remaining
Answer:
After 43 minutes, the bacteria will be 40 remainings.
Step-by-step explanation:
Given that:
Initial population of bacteria [tex]A_o[/tex] = 800
After time (t) = 18 mins
A = 240
Using the model:
[tex]A = A_o e^{k*t}[/tex]
[tex]240=800 e^{k*18}[/tex]
[tex]\dfrac{240}{800}= e^{18k}[/tex]
[tex]0.3= e^{18k}[/tex]
By applying natural log on both sides, we get:
In(0,3) = 18k (In e)
- 1.20397 = 18 k * (1)
18 k = -1.20397
k = -1.20397/ 18
k = - 0.06688
k ≅ -0.07
After time (t), the bacteria population (A) = 40
Now;
[tex]40 = 800 e^{k*t}[/tex]
[tex]\dfrac{40 }{800}= e^{-0.07*t}[/tex]
[tex]0.05= e^{-0.07*t}[/tex]
In (0.05) = -0.07t * In (e)
- 2.9957 = - 0.07t
t = - 2.9957/ -0.07
t = 42.795
t ≅ 43 minutes
Thus, after 43 minutes, the bacteria will be 40 remainings.
if L is parallel to M, find the value of each variable(s)
Answer:
see below
Step-by-step explanation:
5. 9x + 2 = 119° alternate interior angles are congruent
9x = 117
x = 13°
6. 12x - 8 + 104° = 180° same side interior angles are supplementary
12x + 96 = 180
12x = 84
x = 7°
7. 5x + 7 = 8x - 71 alternate exterior angles are congruent
-3x = -78
x = 26°
8. 4x - 7 = 7x - 61 corresponding angles are congruent
-3x = -54
x = 18°
9. 9x + 25 = 13x - 19 corresponding angles are congruent
-4x = -44
x = 11°
13x - 19 + 17y + 5 = 180° straight line adds up to 180°
13(11) - 19 + 17y + 5 = 180
143 - 19 + 17y + 5 = 180
17y + 129 = 180
17y = 51
y = 3°
10. 6x - 7 + 3x - 29 = 180° same side interior angles are supplementary
9x - 36 = 180
9x = 216
x = 24°
6x - 7 = 8y + 17 vertical angles are congruent
6(24) - 7 = 8y + 17
144 - 7 = 8y + 17
137 = 8y + 17
120 = 8y
y = 15°
11. 49 + 3x = 7x - 23 corresponding angles are congruent
-4x = -72
x = 18°
3x = 11y - 1 corresponding angles are congruent
3(18) = 11y - 1
54 = 11y - 1
55 = 11y
y = 5°
12. 5x - 38 = 3x - 4 alternate interior angles are congruent
2x = 34
x = 17°
7y - 20 + 5x - 38 + 90 = 180° sum of triangle interior angle equals 180
7y - 20 + 5(17) - 38 + 90 = 180°
7y - 20 + 85 - 38 + 90 = 180°
7y + 117 = 180
7y = 63
y = 9°
what is the answer to this?
Answer:
[tex] < 1 = 48[/tex]
Step-by-step explanation:
[tex] < 1 + 132 = 180[/tex]
[tex] < 1 = 180 - 132[/tex]
[tex] < 1 = 48[/tex]
because it's a straight angle(180)
Solve the equation sin^2x=3Cos^2X.
I would love to graduate...so thanks in advance!
Answer:
240°
Step-by-step explanation:
[tex]sin^2x=3cos^2x \\ \\ sin^2x=3(1 - sin^2x )\\ \\ sin^2x=3 - 3sin^2x \\ \\ sin^2x + 3sin^2x=3 \\ \\ 4sin^2x=3 \\ \\ sin^2x= \frac{3}{4} \\ \\ sinx= \sqrt{ \frac{3}{4} } \\ \\ sinx= \frac{ \sqrt{3} }{2} \\ \\ sinx= sin \: 60 \degree \\ \\ in \: the \: second \: quadrant \\ sinx= sin \: (180 \degree - 60 \degree ) = sin \: 120 \degree \\ \\ in \: the \: third \: quadrant \\ sin x= sin \: (180 \degree + 60) \degree = sin \: 240 \degree[/tex]
simplify [tex]\sqrt{80} + \sqrt{2\frac{2}{9}[/tex]
Answer:
[tex]\displaystyle \frac{14}{3}\sqrt{5}[/tex]
Step-by-step explanation:
Simplify:
[tex]\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}[/tex]
We must express the mixed fraction into an improper fraction:
[tex]2\frac{2}{9}=2+\frac{2}{9}=\frac{20}{9}[/tex]
[tex]\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}=\displaystyle \sqrt{80} + \sqrt{\frac{20}{9}}[/tex]
Since 80 = 16*5 and 20=4*5
[tex]\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}=\displaystyle \sqrt{16*5} + \sqrt{\frac{4*5}{9}}[/tex]
[tex]\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}=\displaystyle 4\sqrt{5} + \frac{2}{3}\sqrt{5}[/tex]
Adding the fractions:
[tex]\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}=\displaystyle (4 + \frac{2}{3})\sqrt{5}[/tex]
[tex]\mathbf{\displaystyle \sqrt{80} + \sqrt{2\frac{2}{9}}=\displaystyle \frac{14}{3}\sqrt{5}}[/tex]

Step-by-step explanation:
Un agricultor tiene una finca de una hectárea la mitad le dedica a cultivar tomates los 2/5 lo dedica a lechugas y el resto cebollas. A qué fracción dedicará cebollas. B qué superficie dedica a cada cultivo.
The given area of the farm, A_0=1 hectare.
The fraction of the farm for cultivating tomatoes = 1/2
The fraction of the farm for cultivating lettuce = 2/5
The remaining fraction of farm for onion = 1-(1/2+2/5)=1/10
Therefore, the fraction of farm dedicated to onion is 1/10.
Now, the area dedicated to tomatoes = 1/2 of the area of land.
=1/2 x 1 = 1/2 hectare.
The area dedicated to lettuce = 2/5 of the area of land.
=2/5 x 1 = 2/5 hectare.
The area dedicated to onion = 1/10 of the area of land.
=1/10 x 1 = 1/10 hectare.
