The measure of the third angle is 65°
Step-by-step explanation:
Each lapel on a suit jacket is in the shape of a triangle
Two of the three angles of each triangle measures 47 and 68We need to find the measure of the third angleIn a triangle:
∵ The sum of the measures of the interior angles = 180°
∵ The measure of one angle = 47°
∵ The measure of other angle = 68°
- Substitute the measures of the two angles in the rule above
∴ 47 + 68 + measure 3rd angle = 180°
- Add the like terms
∴ 115 + measure 3rd angle = 180°
- Subtract 115 from both sides
∴ measure 3rd angle = 65°
The measure of the third angle is 65°

Isaac purchased a house for $179,300,00. Every year, Isaac makes improvements so that the value of the house goes up by 4%.
Which of the following equations can be used to determine the number of years after purchase, that the value of Isaac's house will
be equal to 5197.230.002
Answer:
The number of years in which house value goes up is 145 years .
Step-by-step explanation:
Given as :
The initial purchased value of the house = p = $179,300,00
The value of house goes up every years at the rate = r = 4%
Let The number of years in which house value goes up = t years
The value of the house after t years = $A = $5197,230,002
Now, According to question
The value of the house after t years = The initial purchased value of the house × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]
I.e A = $p × [tex](1+\dfrac{\textrm r}{100})^{\textrm t}[/tex]
Or,$5197,230,002 = $17930000 × [tex](1+\dfrac{\textrm 4}{100})^{\textrm t}[/tex]
Or, [tex]\dfrac{5197,230,002}{179,300,00}[/tex] = [tex](1+\dfrac{\textrm 4}{100})^{\textrm t}[/tex]
Or, 289.86 = [tex](1.04)^{t}[/tex]
Now, taking Log both side
So, [tex]Log_{10}[/tex]289.86 = [tex]Log_{10}[/tex] [tex](1.04)^{t}[/tex]
or, 2.462 = t × [tex]Log_{10}1.04
or, 2.462 = t × 0.01703
∴ t = [tex]\dfrac{2.462}{0.01703}[/tex]
I.e t = 144.56 ≈ 145
So, Number of years = t = 145 years
Hence The number of years in which house value goes up is 145 years . Answer
To determine the number of years it will take for the value of Isaac's house to reach $5,197,230.002 with an annual appreciation rate of 4%, use the compound interest formula. Solving for the number of years, the approximate result is 84 years.
Isaac purchased a house for $179,300. Every year, the value of the house increases by 4%. To determine the number of years after purchase that the value of Isaac's house will reach $5,197,230.002, we can use the formula for compound interest:
FV = PV × (1 + r)ⁿ
FV is the future value of the house, $5,197,230.002.PV is the present value or the initial value of the house, $179,300.r is the annual increase rate, 4% or 0.04.n is the number of years.We need to solve for n in the equation:
$5,197,230.002 = $179,300 × (1 + 0.04)ⁿFirst, isolate the exponential expression:
(1 + 0.04)ⁿ = $5,197,230.002 / $179,300(1.04)ⁿ ≈ 29Next, apply the natural logarithm to both sides to solve for n:
ln[(1.04)n] = ln(29)n × ln(1.04) = ln(29)n = ln(29) / ln(1.04)n ≈ 83.95 yearsSo, the value of Isaac's house will reach $5,197,230.002 approximately 84 years after purchase.
Maya has $2740 of play money
Emily has $3560 of play money. Maya gives some money to Emily. If Emily ends up with 4 times Maya amount. How much money does each girl has in the end
Answer:
Maya = $1260
Emily = $5040
Step-by-step explanation:
2740+3560 =6300
M + (4M) = 6300
5M=6300
M=6300/5
M=1260
E=5040
Maya has $1260, and Emily has $5040 in the end. Maya gives $1480 to Emily.
How the amount of money was calculatedMaya has $2740, and Emily has $3560.
We're looking for the amount Maya gives to Emily so that Emily ends up with 4 times as much as Maya.
Let M be the amount Maya gives to Emily.
Emily ends up with 4 times Maya's amount:
Emily's amount = 4 * Maya's amount
$3560 + M = 4 * ($2740 - 4M
Simplify:
$3560 + M = $10960 - 4M
$3560 + M + 4M = $10960
5M = $10960 - $3560
5M = $7400
Divide by 5 to solve for M:
M = $7400 / 5
M = $1480
So, Maya gives $1480 to Emily.
To find how much each girl has in the end:
Maya: $2740 - $1480 = $1260
Emily: $3560 + $1480 = $5040
Maya has $1260, and Emily has $5040 in the end.

Otto's investment portfolio consisted of shares of internet stock and copper stock. During the year, the value of his internet shares increased $10\%$, but the value of his copper shares decreased from $\$10{,}000$ to $\$9{,}000$. During the same year, the total value of his portfolio increased by $6\%$. What was the dollar value of his internet shares at the end of the year?
Answer:
44000
Step-by-step explanation:
Let w be the initial value of Otto's internet stock, in dollars. At the beginning of the year, the total value of his portfolio is w+10,000 dollars. At the end of the year, the total value of his portfolio is 1.1w+9,000 dollars. Since increasing by 6% is equivalent to multiplying by 1.06, we have
1.06(w+10,000)=1.1w +9,000
Distributing and collecting terms, we find w=40,000. At the end of the year, his internet stock is worth 40,000* 1.1=44,000 dollars.

Step-by-step explanation:
See the diagram in the coordinate plane attached.
A rhombus has four equal sides and to find the perimeter of the rhombus we have to measure any of the sides of the figure of the rhombus.
The coordinates of the topmost point are (-1,-1) and that of the rightmost point are (3,-3).
Therefore, side length of the rhombus will be
[tex]\sqrt{(- 1 - 3)^{2} + (- 1 - (- 3))^{2}} = \sqrt{20} = 2\sqrt{5}[/tex] units.

Reset
Next
Answer: 24times
Step-by-step explanation:
Formula for the volume of a cylinder = πr²h
Volume of the cone = 1/3πr²h
Therefore the volume of the cylinder = 22/7 x 10² x 20
= 22/7 x 10 x 10 x 20
= 6285.71cm³
Therefore , the volume of the cone = 1/3 x 22/7 x 5² x 10
= 1/3 x 22/7 x 5 x 5 10
= 5500/21
= 261.9cm³
Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water = 6285.71/261.9
= 24times.

Given the diagram below, what is sin (30°) ?
Answer:
A. 1/2.
Step-by-step explanation:
The ratio of the sides of a 30-60-90 triangle is 2:1:√3 where 2 is the hypotenuse. 1 is the shortest leg and √3 is the longest leg.
In the diagram we see that the longest leg is opposite the 60 degree angle.
So the longest leg is 3.5√x and the shortest leg ( from applying the ratios) = 3.5√x / √3.
and the hypotenuse is 2 * 3.5√x / √3 (using the ratios again).
So sin 30 = shortest leg / hypotenuse = 3.5√x / √3 / 2 * 3.5√x / √3
= 1/2.

Every student in the senior class is taking history or science. There are $200$ seniors in the class. If there are $126$ seniors taking history and $129$ seniors taking science, how many students are taking both history and science?
Answer: 55
Step-by-step explanation:
126+129= 255
255-200=55
55 students are taking both history and science.
To solve this, we set up the problem as follows: Let H represent the set of students taking history, S represent the set of students taking science, and N represent the total number of seniors. We're given that N = 200, |H| = 126 (the number of students taking history), and |S| = 129 (the number of students taking science). The number of students taking both can be found by adding the number of students in sets H and S and subtracting the total N. This calculation is often represented by the formula |H ∩ S| = |H| + |S| - N, where |H ∩ S| is the number of students taking both history and science.
Using the formula, we calculate: |H ∩ S| = 126 + 129 - 200 = 55. Therefore, 55 seniors are taking both history and science.

Rational numbers can be expressed as the ratio of two integers. From the list provided, the rational numbers are 72/100 (A), 1 1/3 (C), 8/526 (D), and 5/9 (F). The number π (B) is irrational, and it is unclear if 0.212212221... (E) is a repeating decimal, so it cannot be confirmed as rational without additional information.
Explanation:Rational numbers are numbers that can be written as a fraction, where both the numerator and the denominator are integers and the denominator is not zero.
This includes both terminating and repeating decimals.
A. 72/100 is a rational number because it can be simplified to the fraction 18/25, which is a ratio of two integers.B. π (pi) is not a rational number because it is an irrational number; it cannot be expressed as a fraction of two integers.C. 1 1/3 is a rational number as it is equivalent to the fraction 4/3, a ratio of two integers.D. 8/526 is a rational number as it is already in fraction form with two integers.E. 0.212212221..., if this is a non-terminating, non-repeating decimal, it would be irrational; however, if the pattern repeats at some point, it would be rational. Since the pattern is not explicitly stated as repeating, we cannot assume it is rational.F. 5/9 is a rational number because it is a fraction that represents a ratio of two integers.Thus, the rational numbers from the list provided are A, C, D, and F.
