when finding 6.1 divided by 0.1 how is the decimal point moved?
well, let's just divide them anyway and check it out.
hmmm 6.1 ÷ 0.1, well, when dividing decimals, we can first check the decimals on each hmmm 6.1 has one decimal and 0.1 has one decimal, so for the one decimal on 6.1 0.1 gets one "0" and for each decimal on 0.1, 6.1 gets one "0".
That means we can change the values with no dots to say 610 and 10, so we end up with a division of 610 ÷ 10 = 61. We can write that as 61.0 hmmm woopsie, the dot moved to the right by one slot.

What is Coordinate Geometry?The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.
Not all crossing lines are parallel ones. If the intersecting lines satisfy the following conditions, they are said to be perpendicular lines. Following are the two primary characteristics of perpendicular lines:
The intersection of perpendicular lines is always at a right angle.Two lines will always be parallel to one another if they are perpendicular to the same line.Let's say that lines AB and CD are parallel to one another. Line AB has a slope of m1, whereas line CD has a slope of m2.
If and only if the product of the slopes of the two lines equals negative of unity, two lines are perpendicular to one another.
As a result, the following is the formula for the perpendicular's slope:
m1.m2 = -1
The equation of the line be "y = mx + c".
Equation of the line Perpendicular to the line is 5x - 4y = 16
Therefore, 4y = 5x - 16
⇒ [tex]y = \frac{5}{4}x -4[/tex]
Slope of the line Perpendicular to the required line is [tex]\frac{5}{4}[/tex].
Slope of the required ine be m .
Therefore, m * [tex]\frac{5}{4} = -1[/tex]
⇒ [tex]m = -\frac{4}{5}[/tex].
Equation of the line is ,
[tex]y = -\frac{4}{5}x + c[/tex]
The line passes through (5,-8)
Therefore,
[tex]-8 = \frac{-4}{5}*5 + c[/tex]

Neha drives a car that gets 25 miles per gallon when she is driving in the city and 40 miles per
gallon when she is driving on the highway. Her car's fuel tank will hold 15 gallons of gas. What
equation can we write to represent all the combinations of city miles and highway miles she can
drive on one tank of gas?
1. Record an equation that is a prediction.
Answer:
C/25 + H/40 = 15
Step-by-step explanation:
Let's call C the number of city miles, and H the number of highway miles.
The total gas used is therefore:
C/25 + H/40
The fuel tank holds 15 gallons, so:
C/25 + H/40 = 15
At the beginning of an experiment, a scientist has 176 grams of radioactive goo. After 135 minutes, her sample has decayed to 11 grams. What is the half-life of the goo in minutes? Find a formula for G ( t ) , the amount of goo remaining at time t . G ( t ) = How many grams of goo will remain after 32 minutes?
Answer:
The amount of goo remaining after 32 minutes is approximately 54.7 grams.
Step-by-step explanation:
The half-life of a substance is the amount of time it takes for half of the substance to decay. To find the half-life of the goo in the experiment, we need to solve the equation G ( t ) = G ( 0 ) / 2 for t , where G ( 0 ) is the initial amount of goo and G ( t ) is the amount of goo remaining after time t .In this case, G ( 0 ) = 176 grams and G ( 135 minutes ) = 11 grams, so we can write the equation as follows:11 grams = 176 grams / 2Solving for t , we get:t = 135 minutes * ( 1 / 2 ) = 67.5 minutesThis is the half-life of the goo in the experiment.To find the amount of goo remaining after time t , we can use the equation G ( t ) = G ( 0 ) * ( 1 / 2 ) ^ ( t / t1/2 ) , where G ( 0 ) is the initial amount of goo, t is the time at which we want to find the amount of goo remaining, and t1/2 is the half-life of the goo.In this case, G ( 0 ) = 176 grams, t = 32 minutes, and t1/2 = 67.5 minutes, so we can plug these values into the equation to find the amount of goo remaining after 32 minutes:G ( 32 minutes ) = 176 grams * ( 1 / 2 ) ^ ( 32 minutes / 67.5 minutes )This equation tells us that the amount of goo remaining after 32 minutes is approximately 54.7 grams.

Answer:
d = 9°
Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.

27° + (8d – 9)° = 90°
27° + 8d – 9° = 90°

Given f(x) = √(3+x) and g(x) = √(3-x), you want the domains of various combinations of f and g.
DomainsThe domain of each of these functions is the interval on which it is defined. The domain of the square root function is all argument values greater than or equal to zero.
Domain of fThe argument of the square root will be non-negative when ...
3 +x ≥ 0
x ≥ -3 . . . . . . subtract 3
-3 ≤ x . . . . . . written using left-pointing arrow
Domain of gThe argument of the square root will be non-negative when ...
3 -x ≥ 0
3 ≥ x . . . . . add x
x ≤ 3 . . . . . written using left-pointing arrow
Intersection of domainsAny combination of functions f and g will only be defined on the domain where both f and g are defined. That is, the domain will be the intersection of the domains of f and g:
(-3 ≤ x) ∩ (x ≤ 3) = -3 ≤ x ≤ 3
Domain of f+gThe domain of f+g is the intersection of the domains of f and g.

Domain of f-gThe domain of f-g is the intersection of the domains of f and g.

Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers. If caroline keeps planting flowers at this rate, how long will it take her to plant all 70 flowers that she has?.
It will take 40 minutes for her to plant all 70 flowers that she has. By using proportions, we can find this value.
How to calculate a word problem using proportions?To calculate a word problem using proportions is as follows:
Consider the details of the word problem in proportions as
a : b = c : d
Here, a: b is the ratio of an event, and c : d is the ratio of another event.
Then, to find the value of c we need to reframe the above proportion into
c = ad/b
This is also said to be a cross formula in terms of word problems.
Calculation:It is given that, Caroline is planting flowers in her garden.
She plants her first 7 flowers in 4 minutes.
After 12 minutes, she planted 21 different flowers.
Then, she takes x minutes for planting 70 flowers.
(Since the rate of planting is the same)
So, we can write
70 : 21 = x : 12
⇒ x = (70× 12)/21 = 40 minutes
Therefore, Caroline takes 40 minutes for planting all 70 flowers.

The equation of the line, in slope-intercept form, containing the point ( 5,2. 2) and (9,2. 6) is y=0.025x+2.375 where 0.025 is the value of slope and 2.375 is the y-intercept.
What is an example of a slope intercept form?Take into account the slope-intercept form of the equation y = 6 x + 9 y=6x+9. The x and y intercepts are known. When x = 0, the y-intercept also happens, and when y equals 0, the x-intercept also happens. By setting the value of y to 0, we may find the x-intercept.
What is the slope and y-intercept?The values of the slope and y-intercept reveal details of the relationship between the two variables, x and y. The slope shows how quickly y changes for every unit change in x. When the x-value is 0, the y-intercept shows the y-value.
To calculate the equation of line containing points (5,2.5) and (9,2.6) we will use the formula y=mx+b
Here, m = (y2-y1)/(x2-x1)
So, m = (2.6-2.5)/(9-5)
m= 1/40
m=0.025
Now finding b by using formula y=mx+b using x= 5 and y= 2.5
2.5=(0.025)(5)+b
