Step-by-step explanation:
Parker says that any two congruent acute triangles can be arranged to make a rectangle. Tamika says that only two congruent right triangles can be arranged to make a rectangle. Is either of them correct? Explain your reasoning.
The statement of Tamika is correct.
How many congruent triangles do you need?Recall that we designate an angle as a place where two line meet. The magnitude of the angle could be measured by the use of a compass. A right angle triangle is a triangle that has an angle of ninety degrees as one of the angles.
Let us keep in mind that all the sides of a rectangle must have an angle of ninety degrees. This is because the sum of the angles in a rectangle must sum up to a total of three hundred and sixty degrees.
Having said that; when we consider the statements of the two persons and reason that if we have two right angled triangles, we could be able to make a rectangle because the four right angles that are required could be cut out of the two congruent right angled triangles. This implies that the statement of Tamika is correct.

The mode is the value of the observation that appears most frequently. true or false
The statement 'The mode is the value of the observation that appears most frequently.' is True.
We know that, the mode is the most frequent number.
It is the number that occurs the highest number of times.
The observation occurring the most number of times or which has highest frequency is known as the mode.
For example, in {6, 3, 9, 6, 6, 5, 9, 3} the Mode is 6 as it occurs most often.
There is no mode when all observed values appear the same number of times in a data set.
Therefore, the statement 'The mode is the value of the observation that appears most frequently.' is True.

A fruit stand is swlling mandarin oranges for $6 for 4 pounds. a mandarin orange weighs about 2 ounces. there are 16 oumces in a pound. at this rate, how many mandarin oranges can you buy for $
The number of mandarin oranges one can buy for $9 is 48 oranges. It is calculated using basic arithmetic operations.
What are arithmetic operations?
Arithmetic operations are the basic mathematical operations which deal with simple calculations. It involves addition (+), subtraction (-), multiplication (×), and division (÷). Arithmetic operations can be used to combine two or more expressions in some or the other way.
Calculation of the number of mandarin oranges one can buy for $9
We are given that,
$6 = 4 pounds
Using arithematic operation division,
Dividing by 6 into both sides, we have,
$1 = 4 / 6 pounds
$1 = 2 / 3 pounds
Using arithematic operation multiplication,
Multiplying the above equation with 9 on both sides,
$9 = (2 / 3) * 9 pounds
$9 = 6 pounds - - - - - (1)
According to the given question,
1 orange weighs 2 ounces - - - - -(2)
1 pound = 16 ounces
1 pound = 8 × (2 ounces)
Using equation 2,
1 pound = 8 oranges
Using equation 1,
$9 = 6 (8 oranges)
$9 = 48 oranges
Hence, one can buy 48 oranges for 9 dollars i.e. $9.

Alvin decided to buy Samantha some candy. He bought her 6 lollipops and 5 petits 4 for $1.40 and then he decides to buy Megan 5 lollipops and 6 petits 4 for $1.35. How much did each cost
Lollipops costs $0.15
Petits costs $0.1
How to calculate the cost of lollipops and petits ?let x represent the cost of lollipops
let y represent the cost of petits
6x + 5y = 1.40.........equation 1
5x + 6x= 1.35.........equation 2
From equation 1
6x + 5y= 1.40
6x= 1.40 -5y
x= 1.40-5y/6
Substitute 1.40-5y/6 for x in equation 2
5(1.40-5y/6) + 6y = 1.35
7-25y/6 + 6y= 1.35
7-25y+36y/6= 1.35
cross multiply
7 +11y= 8.1
11y= 8.1-7
11y= 1.1
y= 1.1/11
y= 0.1
Substitute 0.1 for y in equation 1
6x +5y= 1.40
6x + 5(0.1)= 1.40
6x + 0.5= 1.40
6x= 0.9
x= 0.9/6
x= 0.15
Hence the cost of lollipops is $0.15 and cost of petits is $0.1

The probability of the states of nature, after use of bayes' theorem to adjust the prior probabilities based on given indicator information, is called _____.
The probability of natural states after applying the Bayes theorem to modify the prior probabilities in light of available indicator data is known as the posterior probability.
What is posterior probability?The posterior probability is a type of conditional probability that is created by applying the Bayes theorem to update the prior probability with information that is summarized by the likelihood. From an epistemological standpoint, the posterior probability, given prior knowledge and a mathematical model describing the observations available at a specific time, contains all that is known about an uncertain proposition (such as a scientific hypothesis, or parameter values). The present posterior probability may act as the prior in a subsequent round of Bayesian updating following the arrival of new data. The posterior probability distribution often expresses the epistemic uncertainty regarding statistical parameters conditional on a set of observed data in the context of Bayesian statistics.

What do you mean by the unitary method?The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unitary technique, in essence, determines the value of a unit from the value of a multiple. To put it simply, it determines the value of a single unit from a given multiple. How can you figure out the price of one pen if 100 cost Rs. 400? You can reach the solution using the unitary technique. Additionally, after a single unit's value has been established, the values of the other units can be derived by multiplying the original unit's value.
Janine is carrying carrots because of this. There are 20 2-pound bags of carrots in each huge box.
We must determine how many boxes Janine can fill.

What was the sales increase over the year?
million
The increase in sales after 170% increase with the initial sales 3 million is
5,100,000 (5 million and 1 lakh or 51 lakh).
Percentage means a number or a ratio represented in the form of fractions of 100. It is represented using the percentage sign ‘%’. The abbreviations used to represent the percentage are ‘pct’ or ‘pc’. In other words, the percentage is defined as how much of one quantity is made by another quantity and it is evaluated in terms of 100.
We have to increase the value by 170%.
The value of the percentage increase = 170% × 3,000,000
The new value = 3,000,000 + The value of the percentage increase
The new value = 3,000,000 + The value of the percentage increase
=3,000,000 + (170% × 3,000,000) = 3,000,000 + 170% × 3,000,000
=(1 + 170%) × 3,000,000 = (100% + 170%) × 3,000,000
=270% × 3,000,000 = 270 ÷ 100 × 3,000,000
=270 × 3,000,000 ÷ 100 = 810,000,000 ÷ 100
=8,100,000 million.
The actual change = The new value - 3,000,000

which is greater height or radius of cone?
full explanation down below
The 150 m³ cone that has a base radius of 5 meters indicates that the height of approximate length 5.73 meters is greater than the radius (length 5 meters)
How can the height of the cone be found?The given parameters are;
Volume of the cone is V = 150 m³
Base radius of the cone, r = 5 m
The formula for finding the volume of a cone is; [tex]V = \mathbf{\frac{1}{ 3} \cdot \pi \cdot {r}^{2} \cdot h} [/tex]
By plugging in the values for the volume, V and radius, r, of the cone, we have;
[tex]150 = \frac{1}{ 3} \times \: \pi \times {5}^{2} \times h[/tex]
Which gives;
[tex] h = \mathbf{ \frac{150}{ \frac{1}{ 3} \times \: \pi \times {5}^{2} } \approx 5.73} [/tex]

There are 60 people in a choir.
Half of the people in the choir are women.
The number of women in the choir is 3 times the number of men in the choir.
The rest of the people in the choir are children.
the number of children in the choir : the number of men in the choir
= n : 1
Work out the value of n.
Answer:
There are 60 people in the chior so we will be dividing that number up to see how many women men and children there are. Half of them are women, which mean divide 60 by 2 which equals 30. There are 30 women in the choir. The number of women is 3 times compared to men. Since its 3 times we use the commutative property of division. 30 divided by 3 is 10. There are 10 men in the choir. The rest are children. To find the rest of them we will take how many people in the choir we know so far and then subtract from the total: 60. there are 30 women and 10 men which adds up to 40. 60 minus 40 equals 20. There are 20 children in the choir.
Since n = number of men and children:
n = 30
