First of all, to find the area of a triangle you multiply the base * height and divide the result by two (2).
Let's use a triangle which sides are all 2 inches. To find the area, you do 2*2/2 which equals 2.
Now, double each side and each side of the triangle is now 4.
We do 4*4/2 which now equals 8.
The percentage increase from 2 --> 8 is 600%.
The percentage of the old area to the new area is 800%
ANSWER: 600%

A bag has 10 marbles-3 red, t blue, and 2 violet. One marble is drawn and then replaced, and this action is repeated 10 times. The results are recorded in the table.
Which of the given statements is true?
A.) The experimental probability of drawing blue is 1/2
B.) The experimental probability of drawing red is 1
C.) The experimental probability of drawing red is 1/10
D.) The experimental probability of drawing violet is 0
The experimental probability of drawing blue is 1/2. Then, option A is correct.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
It is given that a bag has 10 marbles-3 red, t blue, and 2 violets. The blue marbles will be 5. One marble is drawn and then replaced, and this action is repeated 10 times.
The probability is calculated as:-

Saira is using the formula for the area of a circle to determine the value of LaTeX: \prod∏. She is using the expression LaTeX: Ar^2A r 2where A=50.265 and r=4. Use a calculator to evaluate Saira's expression to find her approximation of the value of LaTeX: \prod∏to the nearest thousandth.
Answer:
3.164
Step-by-step explanation:
Given the area if the circle used by Sarah expressed as
A = πr²
Given
A = 50.265
r = 4
To get π, we will substitute the given values into the formula as shown
50.625 = π{4)²
50.625 = 16π
π = 50.625/16
π = 3.164
Hence her approximate value to nearest thousandth is 3.164
The area of the regular octagon is 10.15 cm2. a regular octagon has sides with lengths of 1.45 centimeters. what is the measure of the apothem, rounded to the nearest hundredth of a centimeter? 1.27 cm 1.75 cm 2.33 cm 2.54 cm
The length of the apothem of the regular octagon will be equal to 1.75 cm
What is a regular octagon?The regular octagon is the shape made up of the 8 sides or also the combination of the 8 isosceles triangles connected together side by side.
Here it is given:
Area of the Octagon = [tex]10.15\ cm^2[/tex]
The side of the octagon=1.45 cm
As we know that the octagon consists of the 8 isosceles triangles so the area of one triangle will be
[tex]= \dfrac{10.15}{8} =1.27\ cm^2[/tex]
Now the area of the isosceles triangle is given as:
[tex]A=\dfrac{1}{2} \times h\times b[/tex]
[tex]1.27=\dfrac{1}{2} \times h\times 1.45[/tex]
[tex]h=1.75\ cm[/tex]
Thus the length of the apothem of the regular octagon will be equal to 1.75 cm

A banker earns a $75,000 annual salary, a 2.35% commission on any approved loans for the bank's business customers, and a fee of $3.75 for each application processed. If the banker has a total of $2.8 million in approved business loans and processes 2,750 applications this year, what are the banker's earnings rounded to the nearest dollar?
Answer:
$15,1113Step-by-step explanation:
Given that the banker base annual salary $75,000
1. a 2.35% commission on $2.8 million is
=(2.35/100)*2,800,000
=0.0235*2,800,000
=$65800
2. a fee of $3.75 for each 2,750 applications processed
=3.75*2,750
=$10312.5
the banker's earning is $75,000+$65800+$10312.5
=$151112.5
to the nearest dollar
=$15,1113

4. The value of y is directly proportional to the value of x. If y = 45 when x = 180, what is the value of y when x = 80?
Given:
The value of y is directly proportional to the value of x.
y = 45 when x = 180.
To find:
The value of y when x = 80.
Solution:
Since the value of y is directly proportional to the value of x, therefore
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.
Putting y=45 and x=180, we get
[tex](45)=k(180)[/tex]
[tex]\dfrac{45}{180}=k[/tex]
[tex]k=\dfrac{1}{4}[/tex]
Substituting [tex]k=\dfrac{1}{4}[/tex] in (i), we get
[tex]y=\dfrac{1}{4}x[/tex]
Put x=80 in this equation.
[tex]y=\dfrac{1}{4}(80)[/tex]
[tex]y=20[/tex]
Therefore, the value of y is 20 when x=80.

Rational Expressions Multiplying I need to know how to do it
Answer:
(x -3)/4
Step-by-step explanation:
You multiply rational expressions the same way you multiply fractions. The numerator is the product of the numerators; the denominator is the product of the denominators. Same factors in numerator and denominator cancel to reduce the product to lowest terms.
[tex]\dfrac{3(x-3)}{3}\cdot\dfrac{x-7}{4(x-7}=\dfrac{x-3}{1}\cdot\dfrac{1}{4}=\boxed{\dfrac{x-3}{4}}[/tex]
We cancelled the factors of 3 from the first expression, and the factors of (x-7) from the second expression. The final product is the product of the reduced rational expressions.
Which of the following numbers is between 0.62 and 1.05?

O 1.1
0.6
Answer:
a
Step-by-step explanation:
b is in the thousandths place, c is over 1.05, and d is no were near in between them
Answer:
1.01
Step-by-step explanation:
0.62 is equivalent to 62/100
0.6 is equal to 60/100, so 0.6 is not the answer.
0.065 is equal to 65/1000
0.6 is equal to 60/100, or 600/1000, so 0.065 is not the answer.
1.1 is equal to 1 and 10/100, while 1.05 is equal to 1 and 5/100, so 1.1 is not the answer.
Therefore, using the process of elimination, 1.01 is the answer.

Answer:
∠2 = 45°
Step-by-step explanation:
Angles 1 and 2 are same-side interior angles where the transversal crosses parallel lines. That means they are supplementary angles.
∠1 +∠2 = 180° . . . . . supplementary angles total 180°
135° +∠2 = 180° . . . . substitute the given value
∠2 = 180° -135° . . . . subtract 135°
∠2 = 45°

Write the converse of the following statement and determine its truth value.
"If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1:8"
Answer:
1) The convers of the conditional statement is;
If the ratio of lefties to righties is 1:8, then a class has 3 left-handed people and 24 right-handed people
2) The convers of the conditional statement is true
Step-by-step explanation:
1) The given statement is presented as follows;
"If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1:8"
The hypothesis = A class has 3 left-handed people and 24 right-handed people = p
The conclusion = The ratio of lefties to righties is 1:8 = q
We have;
If p, then q which is p → q
The converse statement = If q, then p which is q → p
Then the converse of the conditional statement can be written as follows;
If the ratio of lefties to righties is 1:8, then a class has 3 left-handed people and 24 right-handed people
2) Given that the ratio of 3:24 = 1:8, we have that both the hypothesis and the conclusion are true, therefore, the converse of the conditional statement is true.
