The quotient and remainder when −34 is divided by 6 is -6 and 2 respectively.
What is termed as the division?Multiplication is the inverse of division. If 3 groups of 4 add up to 12, 12 divided into three equal groups adds up to 4 in each cluster in division.Each component of a division equation is given its own name.Dividend: The dividend is just the number divided during the division process.Divisor: The divisor is the number whereby the dividend is divided.Quotient: A quotient is an outcome of the division process.Remainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.Dividend = Divisor x Quotient + Remainder
For the given question,
The number -34 is to be divided by 6.
In this, dividend is -34 and divisor is 6.
Now while dividing the number comes should be less than -34.

The length of a rectangle is three times its width.
If the perimeter of the rectangle is 48 in, find its length and width.
length: in
width: in
Length: 18 in.
Width: 6 in.
We can use “x” as the width in this scenario. If the width is x, then the length is 3x, since length is three times the width. The perimeter would be length + length + width + width. Since the perimeter is 48, we could say that:
x + x + 3x + 3x = 48
Which simplifies to 8x=48
If you divide by 8 on both sides, you get
X=6. Then you Can plug 6 back into your x width and 3x length.

She initially spent $100 to purchase soap-making equipment, and the materials for each pound of soap cost $5. Leah sells the soap for $15 per pound. Eventually, she will sell enough soap to cover the cost of the equipment. What will be Leah's total sales and costs be? Write a system of equations, graph them, and type the solution.
Answer:
Equations:
Cost equation C(x) = 100 + 5x
Sales equation S(x) = 15x
Graph provided
Solution at breakeven point i.e. where sales = costs is at x = 10 lbs
Step-by-step explanation:
Total cost = $100 capital cost of equipment + production cost of $5 per pound of soap
Cost equation C(x) = 100 + 5x where x is the number of pounds of soaps produced
Sales Equation S(x) = 15x where x is the number of pounds of soap sold
The break-even quantity (in lbs) of soap to be sold to pay for equipment is when both equations are equal to each other
100 + 5x = 15x
==> 15x = 100 + 5x
==> 15x - 5x = 100 (subtract 5x on both sides)
==> 10x = 100
==> x = 10 lbs of soap
At this quantity, Sales and Costs are evened out

The half-life of a radioactive kind of uranium is 2 years. How much will be left after 4 years, if you start with 776 grams of it?
ANSWER
194 grams
EXPLANATION
We have that the half life of the uranium is 2 years.
This means that it will take 2 years for the uranium to decay to half of its original value.
The formula for exponential decay is:
[tex]y=ab^t[/tex]where y = the value after the decay
a = initial value
b = rate of decay.
t = number of years
First, we have to find b.
We have that 776 grams of uranium will decay to half its amount (388 grams) in 2 years. This means that:
[tex]\begin{gathered} 388\text{ = 776 }\cdot b^2 \\ \Rightarrow b^2\text{ = 388 / 776} \\ b^2\text{ = 0.5} \\ b\text{ = }\sqrt[]{0.5} \\ b\text{ = 0.707} \end{gathered}[/tex]Therefore, after 4 years (t = 4), the amount of uranium left will be:
[tex]\begin{gathered} y\text{ = 776 }\cdot(0.707)^4 \\ y\text{ = 776 }\cdot\text{ 0.25} \\ y\text{ = 194 grams} \end{gathered}[/tex]That is the amount of uranium that will be left after 4 years.

the radius of a circular disk is given as 30 cm with a maximum error in measurement of cm. use differentials to estimate the maximum possible error in the calculated area of the disk.
The calculated area's maximum percentage relative error is approximately 1.33%.
we know that:
Area of the circular disc is given by A = πr²
consider A = πr²
Differentiate both sides with respect to r, we get
dA/dr = 2πr
⇒ dA = 2πr dr
calculate area:
A = πr²
A = π(30)²
A = 900π
A = 2826 cm²
Because of an error in measurement, the radius might actually be as big as 30+0.2 cm
= 30.2 cm
If r is increased from 30 by an amount Δr = dr = 0.2
Then the actual change in the calculated area would be :
ΔA = A(30+Δr)-A(30)
ΔA = A(30.2)-A(30)
ΔA = (30.2)²π - 900π
ΔA = 912.04π - 900π
= 12.04π cm²
So we estimated the maximum error in calculated area as 12.04π cm²
≅ 37.8 cm²
The maximum relative error in calculated area is:
ΔA/A= dA/A = 12.04π/900π
= 0.013
= 1.33 %
The maximum % relative error in calculated area is about 1.33%.

What are Alternate interior angles?
Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal.
Given are two parallel lines.
The two lines are parallel and are intersected by a transversal. Assume
that -
∠1 = (x +3)°
∠2 = (2x - 61)°
Now, the angle at the vertically opposite position with respect to ∠2 will have same measurements. Let's call this ∠3 = (2x - 61)°.
Now, ∠3 and ∠1 are alternate interior angles and their measures will be equal. So, we can write -
∠1 = ∠3
x + 3 = 2x - 61
3 + 61 = 2x - x
x = 64
The value of [x] is 54
Therefore, the value of [x] in the figure given is 54.

Rate of Change: The city’s population decreases by about 1975 people each year. Y-intercept: In year 0, the city's population was about 118 people.
The equation y = –117.5 x + 31,379.9 gives the population y of a city in x years after 1975 , in real world ,
Rate of Change means The city’s population decreases by about 118 people each year , and Y-intercept means In 1975, the city’s population was about 31,380 people.
In the question ,
the equation that gives the population y of a city in x years is
y = –117.5 x + 31,379.9
let us find the population for 1976
So , x = 1 ,
we get , y = –117.5(1) + 31,379.9
y = –117.5 + 31,379.9
y = 31262.4
So, the population in the year 1976 is 31262.4
change in population = population in 1976 - population in 1975
= 31262.4 - 31,379.9
= -117.5
≈ -118
to find the population in the year 1977
x = 2 ,
we get , y = –117.5(2) + 31,379.9
= –235 + 31,379.9
= 31144.9
change in population = population in 1977 - population in 1976
= 31144.9 - 31262.4
= -117.5
≈ -118
From above , we can see that the population is decreasing in the year 1976 and 1977 , by 118 people,
hence , we can say that , the city’s population decreases by about 118 people each year
For population in 1975 , we put x=0 ,
So , y = –117.5(0) + 31,379.9
= 31379.9
≈ 31380
Therefore , the equation y = –117.5 x + 31,379.9 gives the population y of a city in x years after 1975 , in real world ,
Rate of Change means The city’s population decreases by about 118 people each year , and Y-intercept means In 1975, the city’s population was about 31,380 people .

A linear function with the same y-intercept as the one that is represented by the graph is: table 1.
How to calculate the slope of a linear function?In Mathematics, the slope of any linear function can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
At points (-3, -4) and (-1, 2) from table 1, the slope of the line would be calculated as follows:
Slope, m = (2 + 4)/(-1 + 3)
Slope, m = 6/2
Slope, m = 3.
Note: The y-intercept of the line shown on the graph is equal to 5 because the x-value is zero (0) at this point.
By using point (-3, -4), the y-intercept of this line would be calculated by using the slope-intercept form:
y = mx + b
Where:
x and y are the points.b is the y-intercept.m represents the slope.Making y-intercept (b) the subject of formula, we have:
y-intercept, b = y - mx

1 note the other angle at d = 62 ( isosceles triangle)
2 x = 180 - 62 - 62 -25
Answer:
x = 31°
Step-by-step explanation:
since AB = BD then Δ ABD is isosceles with base angles congruent, so
∠ ADB = ∠ BAD = 62°
the sum of the 3 angle in Δ ABD = 180° , so
∠ ABD = 180° - 62° - 62° = 180° - 124° = 56°
∠ ABD and ∠ CBD are a linear pair and sum to 180° , so
56° + ∠ CBD = 180° ( subtract 56° from both sides )
∠ CBD = 124°
the 3 angles in Δ CBD sum to 180° , then
x + 124° + 25° = 180°
x + 149° = 180° ( subtract 149° from both sides )
