frome 12 to 16 in a month what is the percent of increase for that month round if needed
Answer:
33.33%
Step-by-step explanation:
The value of a variable change from 12 units to 16 units in a month.
We have to calculate the percentage increase for that month.
Therefore, the increase of value from 12 to 16 means by (16 - 12) = 4 units
So, the percentage increase for the month is [tex]\frac{4}{12} \times 100 = 33.33[/tex]%. (Rounded to the two decimal). (Answer)

OPTION B: y = [tex]$ \frac{1}{2} $[/tex]x - 2
Step-by-step explanation:
To find the equation of the line substitute the value of x and compare the corresponding value of y.
OPTION A:
y = 2x + 4
Substitute x = 0. We get, 2(0) + 4 = 4
When x = 0, y = -2 [tex]$ \ne $[/tex] 4.
OPTION B:
y = [tex]$ \frac{1}{2} $[/tex]x - 2
Substitute x = 0, we get [tex]$ \frac{1}{2} (0) - 2$[/tex]
= -2
When x = 2, [tex]$ \frac{1}{2}(2) - 2 $[/tex] = 1 - 2
=-1
Similarly, When x = 4, [tex]$ \frac{1}{2}(4) - 2 = 2 - 2 $[/tex]

Triangle ABC has side lengths: V6, V2, and 2/2 units.
The measures of the angles of the triangle are
If the base of the triangle has a length of 16 then the measure of the base angle is
Answer:
90°, 60°, and 30°
60°.
Step-by-step explanation:
The triangle ABC has side lengths √6, √2, and 2√2 units.
It is clear that the triangle ABC is right triangle because (2√2)² = (√6)² + (√2)² that means the side lengths satisfy the Pythagoras Theorem.
Now, if the angle between hypotenuse (2√2 units) and base (√2 units) is [tex]\theta[/tex], then
[tex]\cos \theta = \frac{\sqrt{2} }{2\sqrt{2} } = \frac{1}{2}[/tex]
Hence, [tex]\theta[/tex] = 60°
Therefore, the three angles of the triangle are 90°, 60°, and 30°.
Now, if the base of the triangle is 16 units, then other two side lengths will also change proportionally to remain the triangle a right triangle.
And in that case the base angle will remain 60°. (Answer)

Which of these sets could represent the side lengths of a right triangle?
Group of answer choices
{4, 8, 12}
{6, 8, 10}
{6, 8, 15}
{5, 7, 13}
Answer:
{6, 8, 10} is a set which represents the side length of a right triangle.
Step-by-step explanation:
In a right triangle:
[tex](Base)^{2} + (Perpendicular)^{2} = (Hypotenuse)^{2}[/tex]
Now, in the given triplets:
(a) {4, 8, 12}
Here, [tex](4)^{2} + (8)^{2} = 16 + 64 = 80\\\implies H = \sqrt{80} = 8.94[/tex]
So, third side of the triangle 8.94 ≠ 12
Hence, {4, 8, 12} is NOT a triplet.
(b) {6, 8, 10}
Here, [tex](6)^{2} + (8)^{2} = 36 + 64 = 100\\\implies H = \sqrt{100} = 10[/tex]
So, third side of the triangle 10
Hence, {6, 8, 10} is a triplet.
(c) {6, 8, 15}
Here, [tex](6)^{2} + (8)^{2} = 36 + 64 = 100\\\implies H = \sqrt{100} = 10[/tex]
So, third side of the triangle 10 ≠ 15
Hence, {6, 8, 15} is NOT a triplet.
(d) {5, 7, 13}
Here, [tex](5)^{2} + (7)^{2} = 25 + 49 = 74\\\implies H = \sqrt{74} = 8.60[/tex]
So, third side of the triangle 8.60 ≠ 13
Hence, {5, 7, 13} is NOT a triplet.

the sum of two numbers is 126 and their difference is 42. what are two numbers
Answer:
84, 42Step-by-step explanation:
[tex]x,\ y-numbers\\\\\text{The system of equations:}\\\\\underline{+\left\{\begin{array}{ccc}x+y=126\\x-y=42\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad2x=168\qquad\text{divide both sides by 2}\\.\qquad x=84\\\\\\\text{Put the value of}\ x\ \text{to the first equation:}\\\\84+y=126\qquad\text{subtract 84 from both sides}\\y=42[/tex]
Final answer:
The two numbers that have a sum of 126 and a difference of 42 are 84 and 42.
Explanation:
To find the two numbers whose sum is 126 and whose difference is 42, we can set up a system of equations:
x + y = 126 (Sum of the numbers)
x - y = 42 (Difference of the numbers)
By adding these two equations, we can eliminate y and solve for x:
x + y + x - y = 126 + 42
2x = 168
x = 84
Now that we have the value of x, we can find y by substituting x back into either of the equations. For example:
84 + y = 126
y = 126 - 84
y = 42
Therefore, the two numbers are 84 and 42.

MICKEY AND MINNIE ARE EXPECTING.
THEY ARE A VERY HAPPY COUPLE.
THE DOCTOR SAID THEY ARE HAVING 5 BOYS AND 5 GIRLS.
MICKEY AND MINNIE ARE RATS.
EVERY THREE WEEKS AN ADULT RAT COUPLE CAN HAVE BABIES.
IT TAKES 6 WEEKS FOR A BABY RAT TO BECOME AN ADULT
AND BE OLD ENOUGH TO HAVE A BABY.
ASSUMING MICKEY AND MINNIE WANT TO HAVE AS MANY CHILDREN AS POSSIBLE AND THEIR OFFSPRING WANT TO HAVE AS MANY CHILDREN AS POSSIBLE,
WHAT WILL BE THEIR ENTIRE POPULATION IN ONE YEAR? (52 WEEKS)
(INCLUDING MICKEY AND MINNIE)
(ASSUME EVERY PREGNACY WILL CONSIST OF 5 BOYS AND 5 GIRLS)
Answer: 6, 570
Step by step explanation: If Minnie and Mickey have 5 girls and 5 boys every 3 weeks for 52 weeks this means they will have 17 pregnancies. At the end of one year Minnie and Mickey alone will have produced 170 children. It takes these children 6 weeks to grow up and be ready to reproduce. Every 6 weeks 10 new rats will be able to have children at a rate of 10 per 3 weeks. This means that a single set of 10 offspring will have 100 children every 3 weeks. There will be 8 sets of offspring that can reproduce before the year is over. This means if the sets have 100 children every 3 weeks starting with one set and adding one more set every 6 weeks, at the end of the year the offspring's offspring will total 6,400. 6,400 + 170 will equal 6,570. The total population is 6,570.
The ratio of incomes of two persons is 9:7. The difference in their weekly incomes is $200. What are their weekly incomes?
What’s the answer
Answer:
The weekly savings of first person = $900
The weekly savings of second person = $700.
Step-by-step explanation:
Let us assume the income of first person = $ m
Now, as the difference in the income is $200.
⇒ And the income of first person - income of first person = $200
⇒ Income of second person = m - $200
So, according to the question:
Ratio of Income of First person : Second Person's Income = 9: 7
or, m : ( m - 200) = 9: 7
[tex]\implies \frac{m}{m - 200 } = \frac{9}{7}[/tex]
[tex]7 \times m = (m - 200) \times 9\\\implies 7 m = 9m - 1800\\\implies 7m - 9m = -1800\\\implies -2m = -1800\\m = \frac{1800}{2} = 900[/tex]
or,m = $900
Hence, the weekly savings of first person = $900
and the weekly savings of second person = m - 200 = $900 - 200 = $700.
Final answer:
To find the weekly incomes of two persons with a ratio of 9:7 and a difference of $200, represent their incomes as 9x and 7x. Solving for x, we get $100, so their incomes are $900 and $700 respectively.
Explanation:
The question asks us to solve for the weekly incomes of two persons given that the ratio of their incomes is 9:7 and the difference between their incomes is $200.
Let's represent the incomes of the two persons as 9x and 7x respectively, where x is a common multiplier. According to the information provided,
9x - 7x = $200
Solving for x:
(9x - 7x) = 2x
2x = $200
x = $200 / 2
x = $100
Now calculating each person's income:
Person A: 9x = 9 * $100 = $900
Person B: 7x = 7 * $100 = $700
Therefore, the weekly incomes of the two persons are $900 and $700 respectively.

(a) Express the amount P (in dollars) remaining to be paid in terms of time t (in months). (Give your answer in slope-intercept form.)
(b) After how many months will the student owe $5000?
Answer:
(a) P = - 200 T + 9,400
(b) After 22 months the student will owe $5000.
Step-by-step explanation:
Here, the amount loaned out to the student = $9,400
The installment amount of each month = $200
(a) P : Amount remaining to be paid
T: time in months
Now, the remaining amount = Actual amount - Amount paid in T months
or, P = 9,400 - $200 (T)
⇒ P = - 200 T + 9,400 ( y = mx + C form)
(b) The remaining amount left = $5000
As we know, P = 9,400 - $200 (T)
⇒ 5,000 = 9,400 - 200 T
⇒200 T = 9,400 - 5,000 = 4,400
⇒ T = 4400/200 = 22
or T = 22 Months
Hence, After 22 months the student will owe $5000.

Answer:
Median = 46.5
Minimum = 32
Maximum = 62
Lower quartile = 38
Upper quartile = 59
Step-by-step explanation:
Before we can proceed to solving any of these, it is best you arrange your data first from least to greatest
32 34 37 39 41 45 48 53 58 60 61 62
First we have the median. The Median is the middle value. In this case we an even number of data, which is 12 data points. The middle value of the data would be found in between the 6th and 7th data point:
45 and 48
To get the middle value, you need to solve for the value that is in the middle of 45 and 48 by getting the sum of both numbers and dividing it by two.
45 + 48 = 93
93 ÷ 2 = 46.5
The minimum and maximum value is merely the least and greatest number.
Here we have:
Minimum = 32
Maximum = 62
To get the lower and upper quartiles, just remember that quartiles divide the data into 4 equal parts. All you need to do is find the value that is in between each quarters of the data:
Q1 (Lower) Q2(Median) Q3(Upper)
32 34 37 | 39 41 45 | 48 53 58 | 60 61 62
Like the median, we will find the value that comes in between each quarter.
Q1
37 + 39 = 76
76 ÷ 2 = 38
Lower quartile = 38
Q3:
58 + 60 = 118
118 ÷ 2 = 59
Upper quartile = 59

The lengths of the sides of a triangle are in the extended ratio 8 : 9 : 10. The perimeter of the triangle is 81 cm. What are the lengths of the sides?
The lengths of the sides are 24cm, 27cm and 30cm.
Step-by-step explanation:
The ratio of lengths is 8:9:10
Perimeter = 81 cm
Let x be the length of side.
Therefore,
The length of sides is 8x, 9x and 10x.
Perimeter is the sum of 3 sides, therefore,
[tex]8x+9x+10x=81\\27x=81[/tex]
Dividing both sides by 27;
[tex]\frac{27x}{27}=\frac{81}{27}\\x=3[/tex]
Therefore, the lengths of sides are [tex]8(3), 9(3)\ and\ 10(3)[/tex]
The lengths of the sides are 24cm, 27cm and 30cm.

The lengths of the sides of the triangle are 24 cm, 27 cm, and 30 cm.
Explanation:To find the lengths of the sides of the triangle, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter. Let's assume the common ratio between the sides is 'x'. So, the lengths of the sides can be written as 8x, 9x, and 10x. According to the problem, the perimeter of the triangle is 81 cm.
Therefore, 8x + 9x + 10x = 81.
Combining like terms, we get 27x = 81.
Dividing both sides by 27, we find that x = 3.
Substituting this value back into the lengths of the sides, we find that the lengths are 8x = 8(3) = 24 cm, 9x = 9(3) = 27 cm, and 10x = 10(3) = 30 cm.
