Jack use the place value chart below to show 1,826.5. Jack divided 1,826.5 by a number to get a quotient of 18.265 which he wrote on the second line of the chart. What number did Jack divide 1,826.5 by to get a quotient of 18,265?
Answer:
100Step-by-step explanation:
Let the number we are looking for be x. If Jack divided 1,826.5 by the number to get a quotient of 18.265, to get the number we will solve the equation;
1,826.5/x = 18.265
Cross multiply
1826.5 = 18.265x
Divide both sides by 18.265
18.265x = 1826.5
18.265x/18.625 = 1826.5/18.625
x = 100
Hence Jack divide 1,826.5 by 100 to get a quotient of 18.265
Here, we are required to find the number Jack divide 1,826.5 by to get a quotient of 18,265?
The number is 100
First, it is important to form an expression from the data given;
Let the no. which Jack divided 1,826.5 by be x.
The result of the division yields a quotient of 18.265.
From the statements above;
1,826.5/x = 18.265
Therefore, 1826.5 = 18.265x.
Therefore, x = 1826.5/18.265 = 100.
Therefore,
the number which Jack divided 1,826.5 by to get a quotient of 18.265 is x = 100.

2(x - 3) + 5x < 9x - 14
how do you solve this
Answer:
x>4
Step-by-step explanation:
Use the distributive property to multiply 2 by x−3.
2x−6+5x<9x−14
Combine 2x and 5x to get 7x.
7x−6<9x−14
Subtract 9x from both sides.
7x−6−9x<−14
Combine 7x and −9x to get −2x.
−2x−6<−14
Add 6 to both sides.
−2x<−14+6
Add −14 and 6 to get −8.
−2x<−8
Divide both sides by −2. Since −2 is <0, the inequality direction is changed.
x>-8/-2
Divide −8 by −2 to get 4.
x>4
Please give me the Brainliest answer!!!!
Answer:
x=4
Step-by-step explanation:
First you would distribute the 2 to get
2x-6+5x<9x-14
then you would combine like terms to get 7x
7x-6<9x-14
Third you would take the 7x across to the 9x making 2x (because you change the sign when moving across the =) so
-6<2x-14
Then bring the -14 across to the -6 making it 8
8=2x
then divide both sides by 2

Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite number, sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

15 members of the Drama Club can make set decorations for their musical in 12 hours. After 4 hours have passed, a few teachers came to help, and the group completed the remaining work in 6 hours. How many teachers helped?
PLEASE help!!! I WILL AWARD BRAINLIEST.
Answer:
5 teachers
Step-by-step explanation:
We know that the 15 members finished 1/3 of the job in 4 hours. When the teachers came they finished 2/3 of the job in 6 hours. So they finished 1/3 of the join in 3 hours of we simplify it.
4 hour: 15 minutes
3 hour: ?
15/3 x 4= 20 teaches. Then we do 20-15=5 because there were originally 15 members.
The time spent and the number of people are illustrations of ratio and proportions.
5 teachers helped the 15 members of the drama club
We have:
[tex]t= 12hrs[/tex] --- time
[tex]n = 15[/tex] --- members of the drama club
After four hours, the amount of time left is 8 hours.
So, we have:
[tex]15\ members \to 8\ hours[/tex]
But the teachers joined them, and they finished in 6 hours.
So, we have:
[tex](x + 15) \to 6\ hours[/tex]
Where x represents the number of teachers
Rewrite as:
[tex]15\ members \to 8\ hours[/tex]
[tex](x + 15) \to 6\ hours[/tex]
Multiply
[tex](x + 15) \times 6 = 15 \times 8[/tex]
[tex]6x + 90 = 120[/tex]
Collect like terms
[tex]6x = 120 - 90[/tex]
[tex]6x = 30[/tex]
Divide both sides by 6
[tex]x = 5[/tex]
Hence, 5 teachers helped them.

What is Modulus Function?
Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the equation be represented as A
Now , the value of A is
| x + 5 | = -9 be equation (1)
On simplifying the equation , we get
The modulus function always returns a positive value
So , when x = 4
Substitute the value of x = 4 in the equation , we get
| 4 + 5 | = -9
| 9 | = -9
And , 9 ≠ -9
Therefore , the equation is False
Hence , the solution is false and the modulus function returns a positive value

Find cos2θ if sinθ=11/61
Answer:
given cos(2θ) = 1 - 2 sin²(θ)
=> cos(2θ) = 1 - 2(11/61)²
=> cos(2θ) = 1 - 2* 121/3721
=> cos(2θ) = 1 - 242/3721
=> cos(2θ) = 3479/3721
Step-by-step explanation:
The value of cos 2θ is = 3479 / 3721 or 0.9349
What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the value of sin θ = 11 / 61
So , the value of cos 2θ = 1 - 2sin²θ
On simplifying the equation , we get
sin θ = 11 / 61
sin²θ = ( 11/61 )²
So , substituting the value in the equation , we get
cos 2θ = 1 - 2sin²θ
cos 2θ = 1 - 2( 11/61 )²
= 3721 - ( 242 / 3721 )
= 3479 / 3721
cos 2θ = 0.9349
Therefore , the value of cos 2θ = 0.9349
Hence , The value of cos 2θ is = 3479 / 3721 or 0.9349

Jim and Lou compare two numbers. Jim thinks eight-hundredths is ten times larger than eight thousandths. Lou thinks eight-thousandths is ten times larger than eight hundredths. Who is correct?
Jim or Lou
Answer:
Lou is correct
Step-by-step explanation:
Let's analyze each statement.
First statement says:
"Jim thinks eight - hundredths is ten times larger than eight - thousandths.
What he is saying is that ten times of eight thousandths is lesser than eight - hundredths.
Now, expressing this in numbers gives:
800/8000 = 10
By inspection, we can see that 800/8000 is equal to 1/10 and not 10 that is given.
Thus, the statement is not correct.
Second statement says;
Lou thinks eight - thousandths is ten times larger than eight hundredths.
What he is saying is that ten times of eight hundredths is smaller than eight thousandths. Expressing this in numbers gives;
8,000/800 = 10
By inspection, 8000/800 gives 10 which corresponds to what is given.
Thus, the statement is correct.
Thus, Lou is correct.

A rectangle has a length of 8.2 cm and a height of 42 mm. What is the area of the square in square millimeters?
Answer:
The area of triangle is 3444 mm².
Step-by-step explanation:
First, you have to convert the length of square into millimeters :
[tex]1cm = 10mm[/tex]
[tex]8.2cm = 10mm \times 8.2[/tex]
[tex]8.2cm = 82mm[/tex]
Next, you have to apply area of square formula, A = length×height :
[tex]area = length \times height[/tex]
[tex]let \: length = 82,height = 42[/tex]
[tex]area = 82 \times 42[/tex]
[tex]area = 3444 {mm}^{2} [/tex]
Answer:3,444 mm^2
Step-by-step explanation:
1 cm is 10 mm, so 8.2 cm is 82 mm. 82 mm x 42 mm = 3,444 mm^2

D)75,000n + 4,800 = 80,000 + 3,900n
Answer:
Step-by-step explanation:
C
The required expression that represents the number of years it will take Catherine to earn the same salary as Lola is 75,000n + 4,800n = 80,000n + 3,900n. option C is correct.
Given that,
Catherine earns a yearly salary of $75,000. Lola earns a yearly salary of $80,000. Catherine will receive a salary increase of $4,800 per year, and Lola will receive a salary increase of $3,900 per year.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of years be n
Catherine's income after n year = 75000 + 4800n
Lola's income after n year = 80000 + 3900n
According to the question,
75,000n + 4,800n = 80,000n + 3,900n
Thus, the required expression that represents the number of years it will take Catherine to earn the same salary as Lola is 75,000n + 4,800n = 80,000n + 3,900n. Option C is correct.

if a man originally payed $3300 in property taxes, what will his new tax payment be if he saves 9% this year?
Answer:
$3003
Step-by-step explanation:
Set it up as an fraction
9/100 = x/3300
Cross multiply
100x = 29700
Simplify
100x/100 = 29700/100
Isolate the x
x = 297
297 is how much they will save this year. To find out how much he will pay subtract x from his original payment.
3300 - 297 = $3003
