Which of the following numbers is between 0.62 and 1.05?
01.01
O 0.065
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

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.
I’m out of school right now and i don’t know what the answer is this is the question. What’s the mean for 17 9 11 and 7?
Answer:
11
Step-by-step explanation:
Given the following question:
[tex]17,9,11,7[/tex]
To find the mean of any given data set we need to add all the values together and then divide that answer by the total amount of values in the data set.
[tex]17,9,11,7[/tex]
[tex]17+9+11+7[/tex]
[tex]9+11=20[/tex]
[tex]20+17=37[/tex]
[tex]37+7=44[/tex]
[tex]=44[/tex]
Now divide the answer by the total amount of values:
[tex]44[/tex]
[tex]a=4[/tex]
[tex]44\div4=11[/tex]
[tex]m=11[/tex]
Which means the mean of this given data set is "11."
Hope this helps.
Answer:
Mean = 11Step-by-step explanation:
The mean is the average number of the data.
Given data: 17, 9, 11, and 7To calculate the mean of the data, divide the sum of the data by the total numbers in the data. The quotient will be the average of the data.
[tex]\dfrac{17 + 9 + 11 + 7}{\text{Total digits in the data}}[/tex]
We can see 4 digits included in the data. Thus, the sum of the data will be divided by 4.
[tex]\dfrac{17 + 9 + 11 + 7}{4}[/tex]
Now, let's solve for the mean.
[tex]\dfrac{17 + 20 + 7}{4}[/tex]
[tex]\dfrac{44}{4} = 11[/tex]
Thus, 11 is the mean.

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

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.

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

The difference of two number is 2 and product of them is 224. Find the Numbers if both of them are negative.
Answer:
The numbers are 14 and 16.
Step-by-step explanation:
Equation:
x (x - 2) = 224
Solution:
x (x - 2) = 224
x² - 2x = 224
x² - 2x - 224 = 0
Now, we ended up with a trinomial. To find the two numbers, we need to factor it.
Factoring Trinomials
Trinomial is a polynomial with three terms which are connected by plus or minus notations. It is expressed as a² + b + c.
To factor, we need to follow these steps:
1. Find the factors of "ac" that when combined it will result to "b".
2. When "c" is positive, the sign in each binomial is the same as "b".
3. When "c" is negative, the sign in each binomial is different.
4. Write as the product of two binomials ( )( ).
Let us continue.
x² - 2x - 224
(x - 16)(x + 14)
Therefore, x = 16 and x = -14.
Since we are looking for a positive value, we are going to use the positive value of x and that is 16.
Larger number is 16.
x - 2 = 16 - 2 = 14
Smaller number is 14.
Final Answer:
The two numbers are 14 and 16.
Checking:
x (x - 2) = 224
16 (16 - 2) = 224
16 (14) = 224
224 = 224 ✔
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
