Round 7, 165.482 to the nearest hundredth.
O 7, 200
O 7, 165.48
O 7, 165.49
O 7, 165.5
Answer:
7, 165.482 ≈ 7,165.48
Step-by-step explanation:
7, 165.482
Locate the hundredth:
7, 165.482
Check the number to the left:
7, 165.482
If the number is greater than or equal to five, we round up.
If the number is less than four, we round down.
2 is less than four.
Therefore:
7, 165.482 ≈ 7,165.48
The given number rounded to the nearest hundredth is 7, 165.48.
The given decimal number is 7,165.482.
We need to round 7,165.482 to the nearest hundredth.
How to round the decimal number to the nearest hundredth?To round a number to the nearest hundredth, look at the next place value to the right (the thousandths this time). Same deal: If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredth place, and then remove all the digits to the right.
Now, in the number 7,165.482 digits, the thousandth place is 2.
So, the number to the nearest hundredth is 7, 165.48
Therefore, the given number rounded to the nearest hundredth is 7, 165.48.

HELP A GIRLL OUT I GAVE YOU ALL MY POINTS!! HELPP! 1. a. What is James’s new texting speed if he practices for only 1 month? __________ b. What is James’s new texting speed if he practices for 2 months? ____________ c. What is his new texting speed if he practices for 3 months? _____________ 2. Write an algebraic equation that gives James’s texting speed s for m months of practice. 3. solve the equation from question 2 to determine how many months of practice it will take before james texting speed reaches 8 characters per second. Lynda would also like to complete in the same speed texting completion as james she currently texts at the rate of 4 characters per second but will only have 10 months to practice before the completion. 4. if Lynda wants to text at least 8 characters per second like james then the equation 10r+4=8 could be used to model this situation. Solve for r. 5. Explain what the variable r represents in the equation given in question 4. 6. Consider the equation 8x+5=37 write a real life scenario that this equation could model.
Answer:
1. a. His new texting speed after one month is 2 + 1/2 = 2.5 characters per second.
b. After two months it will be 2 + (1/2) * 2 = 3 characters / second.
c. Answer is 2 + 1/2 * 3 = 3.5 characters/second/.
2. The answer is s = 1/2m + 2
3. To solve for m we write 8 = 1/2m + 2 → 6 = 1/2m → m = 12 months.
4. 10r + 4 = 8 → 10r = 4 → r = 0.4
5. The variable r represents the rate she must increase her texting speed by per month.
6. A scenario could be "Allison has 37 marbles in a jar. She took out 5 from the jar and wants to divide the remaining amount equally among her 8 friends. How many marbles does each friend get?".
The points plotted below satisfy a polynomial equation. In what ranges of x-values must there be a root of the graph? Check all that apply! I will mark brainliest.
Answer:
Correct options are A and B.
Step-by-step explanation:
From the given graph it is clear that the given points lie on a parabola because they in U-shape.
We need to find the ranges of x-values such that there must be a root of the graph.
The point (-3,2) lies above the x-axis but point (-2,-2) lies below the axis. It means when these points are connected by a curve then the curve intersects the x-axis
So, one root of the graph lies in the range -3 to -2.
Similarly, point (1,-1) lies below the x-axis but point (2,3) lies above the axis. It means when these points are connected by a curve then the curve intersects the x-axis
So, one root of the graph lies in the range 1 to 2.
Therefore, the correct options are A and B.

Answer:
(0,3)
Step-by-step explanation:
y = 2x+3
y = -3x+3
Since both equations are equal to y, set them equal to each other
2x+3 = -3x+3
Subtract 3 from each side
2x = -3x
Add 3x to each sdie
2x+3x = -3x+3x
5x =0
Divide by 5
x=0
Now solve for y
y =2x+3
y = 0+3
y=3
(0,3)
Answer:
(0,3)
Step-by-step explanation:
y = 2x+3
y = -3x+3
2x+3 = -3x+3
2x = -3x
2x+3x = -3x+3x
5x =0
x=0
The solve for y
y =2x+3
y = 0+3
y=3
(x,y)=(0,3)
Then (0,3) will be your answer!

how many solutions does y=5-2x and4x+2y=10
Answer:
infinite solutions
Step-by-step explanation:
y=5-2x
4x+2y=10
Multiply the first equation by 2
2y = 10 -4x
Add 4x to each side
4x+2y = 10
This is identical to the second equation
This means they are the same line, so there are infinite solutions along the line

The volume of the triangular block is 4 cubic inches. What is the approximate length of y? Round to the nearest 10th of an inch.
Answer:
2.8 in
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular end and h is the length )
A = [tex]\frac{1}{2}[/tex] × x × x = [tex]\frac{1}{2}[/tex] x² , thus
V = [tex]\frac{1}{2}[/tex] x² × x = 4 , that is
[tex]\frac{1}{2}[/tex] x³ = 4 ( multiply both sides by 2 )
x³ = 8 ( take the cube root of both sides )
x = [tex]\sqrt[3]{8}[/tex] = 2
Using Pythagoras' identity on the right triangle with hypotenuse y, then
y² = x² + x² = 2² + 2² = 4 + 4 = 8 ( take the square root of both sides )
y = [tex]\sqrt{8}[/tex] ≈ 2.8 in ( to the nearest tenth )

WILL GIVE BRAINLIEST!!!!! The figure below shows a line graph and two shaded triangles that are similar Which statement about the slope of the line is true? It is 3 throughout the line. It is 1/3 throughout the line. The slope from point O to point A is 1/3 times the slope of the line from point A to point B. The slope from point O to point A is 3 times the slope of the line from point A to point B. (click on the picture below)
Answer:
The slope from point O to point A is 3 times the slope of the line from point A to point B.
Step-by-step explanation:
The slope of the entire line is 1. The slope from point A to point B is also 1. 1 multiplied by 3 is still 1, which means that the slope from point O to point A is also 1.

Answer:
100
Step-by-step explanation:
A rhombus is split into four right triangles
The base of one is 5 and the hypontenuse is 10
So remember x^2y^2=z^2
5^2=25
25+y^2=100
Ok so y is between 8 and 9 so lets just use 8 first
5*8*1/2=20
there are 4 triangles so 20*4=80
now same thing with 9
5*9*1/2=22.5
22.5*4=90
your answer is between 80 and 90
btw i might have gotten the answer wrong but idk if u were supposed to have an exact answer and also idk if the "10" was the hypontheses but since u were probably offline i answered it

Write the contrapositive of the conditional statement. Determine whether the contrapositive is true or false. If it is false, find a counterexample.
Answer:
D) A statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. True
Step-by-step explanation:
Information is missing in the question, which would be the following:
A converse statement is formed by exchanging the hypothesis and conclusion of the conditional.
The options for answering the question are also missing, which by investigating I could know that they are as follows:
A) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. True
B) A statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. False; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional.
C) A non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. False; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional.
D) A statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. True
Now we have that a conditional statement has the form of whether A then B.
Also, A contradictory statement is when we exchange the hypothesis and the conclusion of the sentence and deny them both. It has the following form if not A, then not B.
Therefore the answer is D)

Permutation helps us to know the number of ways an object can be arranged in a particular manner. The number of ways in which 6 marbles can be put in three different jars is 720.
What is Permutation?Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.
[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
Given that there are 6 marbles and 3 different jars. Therefore, The number of ways in which 6 marbles can be put in three different jars is,
Number of ways = ⁶P₃ × 3!
= 120 × 6
= 720
