We need to use the place values to compare different numbers.
By only looking at the place value, we can see that the largest number is: 0.1
Let's see how to get the solution.
We can define place value as the place where a digit is with respect to the decimal point.
The digits that are at the far left are the larger ones, for example in:
11
The left one represents 10, while the right one represents 1:
10 + 1 = 11
The same happens when we look at the right of the decimal point, there the digits at the left will be larger than the ones at the right.
0.10 is larger than 0.01
From this, we can see that for the set:
{0.1, 0.02, 0.003, 0.0004, 0.00005}
The largest number will be the one with the leftmost first digit different than zero, which is the first one: 0.1

The total cost of a shopping trip was $123.35? Layla bought 4 skirts and a pair of shoes for $35.67. Which equation can be used to find the price of each skirt?
A. 123.35 = 35.67x +4
B. 35.67 = 123.34x + 4
C. 35.67 = 4x + 123.34
D. 123.35 = 4x + 35.67
Answer: D
Step-by-step explanation: The 4 skirts cost are unknown which makes up the 4x and the extra pair of shoes adds on to the cost by 35.67.
The endpoints of AB are A(–7, –6) and B(5, 6). What are the coordinates of point C on AB that is 1/3 the distance from point A to point B?
Answer:
C
Step-by-step explanation:
find the distance between the two points and divide that by 3 first,
then you estimate the point that is from point A with that 1/3 distance
The coordinate of point C such that point C on AB that is 1/3 the distance from point A to point B is (-3,-2) so option (C) will be correct.
What are coordinates?A pair of numbers is used to express a point's position on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).
Coordinate a point with intercept m: n and bounded by coordinate (x₁, y₁) and (x₂, y₂) is given by
x = [m(x₂) + n(x₁)]/(m + n)
y = [m(y₂) + n(y₁)]/(m + n)
Here m = 1/3 and n = (1-1/3) = 2/3
And coordinates A(–7, –6) and B(5, 6).
So,
x = [ 1/3(5) + 2/3(-7) ]/ 1
x = -3
And,
y = [ 1/3(6) + 2/3(-6) ]/ 1
y = -2
So (-3,-2) will be the coordinate of point C.
Hence "The coordinate of point C is (-3,-2).

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
y = 3x+1
Step-by-step explanation:
Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:
7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.
we now can make the first part of the equation:
y = 3x + b
Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).
-5 = 3x-2 + b
you get:
-5 = -6+b
which is equal to:
b = 1
So, putting b back in the equation, you get:
y = 3x+1

A certain blueprint shows two fences. Fence A is 1 1/5 yards long but is 1 1/2 inches long on the 2 blueprint. What is the unit rate for inches per yard on this blueprint? If fence B is 4 yards long, how long is fence B on the blueprint?
Answer:
Unit rate = 1.25 inches per yard
Length of fence B on the blueprint = 5 inches
Step-by-step explanation:
We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.
This means it's 1.2 yards long but 1.5 inches on the blueprint.
Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard
fence B is 4 yards long.
Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.

Let us explain factorization by grouping
In the expression of 4 terms ax + by + bx + ay
Take every two terms have a common factor in a bracket
(ax + ay) + (bx + by)Take the common factor out of the brackets
a(x + y) + b(x + y)Take the bracket as a common factor
(x + y)(a + b)Let us do these steps with our question
∵ ab - a - b + 1 is an expression of 4 terms
→ Take ab and a in a bracket, -b and 1 in another bracket
∴ ab - a - b + 1 = (ab - a) + (-b + 1)
→ Take a as a common factor from the 1st bracket and -1 from
the 2nd bracket
∴ (ab - a) + (-b + 1) = a(b -1) + -1(b - 1)
→ Take the bracket (b - 1) as a common factor
∴ a(b -1) + -1(b - 1) = (b - 1)(a + -1)
∵ (+)(-) = (-)
∴ (b - 1)(a + -1) = (b - 1)(a -1)
→ Change the order of the bracket
∴ (b - 1)(a -1) = (a - 1)(b - 1)
∴ ab - a - b + 1 = (a - 1)(b - 1)

If you can walk 5.3 miles in 3.2 hours, how many minutes does it take to walk 1.74 miles?
Answer:
Let x be the number of hours for 1.74 miles
5.3 miles 3.2 hours
1.74 miles x
When you cross multiply the above numbers you get the equation:
5.3x = 5.568
x = 5.568/5.3
x = 1.05
Therefore it takes 1.05 hours to walk 1.74 miles.

In the figure, m∠1=(2x+40)° and m∠8=(12x−20)° . PLEASE HELP
For what value of x is m∥n ?
Enter your answer in the box.
x =
Answer: x = 6
Step-by-step explanation:
Angles 1 and 8 are alternate exterior angles, so they are equal.
so you can create an equation to solve for x
12x−20 = 2x+40 Subtract 2x from both sides. Add 20 to both sides
10x = 60
x = 6
if you need the m∠1, Substitute 6 for x. (2x+40)° 2(6) +40= 12+40 m∠1= 52°
m∠8=(12x−20)° 12(6) - 20 = 72-20 m∠8 = 52°

Lcm of 36 75 80 is what if you know plz send the answer
Answer:
3600
Step-by-step explanation:
lcm stands for "lowest common multiple"
the lcm is 3600 when done with the prime factorization process
Answer:
3600
Step-by-step explanation:
Express each number as a product of its prime factors, that is
36 = 2² × 3²
75 = 3 × 5²
80 = [tex]2^{4}[/tex] + 5
Now multiply each factor the greatest number of times it occurs in each of the 3 numbers.
2 → 4 times (that is [tex]2^{4}[/tex] )
3 → twice (3² )
5 → twice (5² )
Thus
LCM = [tex]2^{4}[/tex] × 3² × 5² = 16 × 9 × 25 = 3600

The equation of the line in the graph is y=

Answer:
y= -1x +1
Step-by-step explanation:
This graph represents −x−2y=−4 .
Which ordered pair is in the solution set of −x−2y≤−4 ?
A. (−4, 1)
B. (−1, 4)
C. (−4, −1)
D. (4, −1)
Answer:
B
Step-by-step explanation:
We have the equation [tex]-x-2y=-4[/tex] and we want to find which ordered pair is in the solution [tex]-x-2y\leq -4[/tex]
First, let's convert the inequality to slope-intercept form. So, we have:
[tex]-x-2y\leq-4[/tex]
Add x to both sides:
[tex]-2y\leq x-4[/tex]
Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:
[tex]y\geq- \frac{1}{2}x+2[/tex]
Therefore, our original inequality will be the same as above.
Notice that our y is greater than our equation.
Therefore, the shaded area will lie above our line.
So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.
(-4, 1) is below our line, so it's not a solution.
(-1, 4) is above our line. So, (-1, 4) is our answer.
(-4, -1) is again below our line. So, it's not a solution.
Finally, (4, -1) is also below our line, so it's not a solution.
Therefore, our final solution is B: (-1, 4).
Let's check this. Substitute -1 for x and 4 for y. This yields:
[tex]-(-1)-2(4)\stackrel{?}{\leq}4[/tex]
Multiply:
[tex]1-8\stackrel{?}{\leq}{4}[/tex]
Subtract:
[tex]-7\stackrel{\checkmark}{\leq}4[/tex]
So, (-1, 4) is indeed our solution.
And we're done!
