If Randy sells 8 times as many vacuum cleaners as Janice, and Janice sells 690 vacuum cleaners per year, on average, how many does Randy sell each month
Randy sells, in average, 460 vacuum cleaners per month.
How many vacuum cleaners does Randy sell each month?.
First, we know that Janice sells 690 units per year.
There are 12 months in a year, so the amount that she sells, in average, per month is:
J = 690/12 = 57.5
This means that Janice sells, in average, 57.5 units per month. And Randy sells 8 times as many, then we can solve the product:
R = 8*57.5 = 460
This means that Randy sells 460 units per month.

What is the (LCD) of 3/5 and 5/6
Answer: 30
Step-by-step explanation:
A LCD, or least common denominator, is the lowest common multiple of both denominators.
Multiples of 5: 0, 5, 10, 15, 20, 25, 30, 35, 40, ...
Multiples of 6: 0, 6, 12, 18, 24, 30, 36, 42, 48, ...

30

https://brainly.com/question/17498894
The first step that we should take before attempting to solve any problem is to understand what the problem statement is asking for us to do and what is given to us to help us achieve that goal. In this case, the problem is asking us to determine the LCD or least common denominator of two numbers. We are provided with two fractions that we will use to help determine our solution. However, before solving for the LCD let us first define what LCD means.
Least Common Denominator ⇒ LCD is a term that is used to help describe a number that can be used in the bottom of the fraction (also known as a denominator) that is common between two numbers. For example, the LCD between 2 and 5 is 10 because that is a time where both of them can be equal to.Looking at our problem we can see that the denominators that are given to us is 5 and 6 so let us determine the multiples of them until we have a duplicate.
Multiples of 5 ⇒ 5, 10, 15, 20, 25, 30Multiples of 6 ⇒ 6, 12, 18, 24, 30Now that we have determine the multiples of 5 and 6 we were able to see that the lowest duplicate that we have is at 30 which means that 30 is our LCD.

if 6 men. 8 women and 16 boys together can do a piece of work in 288 days by working 6 hours each day in how many days can 12 men, 18 women and 28 boys complete the same & work by working 8 hours each day? The work efficiency of men, women and boys proportion 3:2:1 respectively?
Answer:
144 days
Step-by-step explanation:
Let's put the efficiency in terms of b
m = 3b w = 2b b=b
starting with 6 m = 18 b
8w = 16 b
16b = 16 b total 50 b
then increase 12m = 36b
18w = 36b
28b = 28 b total = 100 b
You doubled 'b' workers so work time will be halved to 144 days

The volume-to-surface-area ratio would be better for an ice cube is the highest possible one.
How to explain the volume?When you put ice into your drink, the goal is to have the ice chill your drink. This takes time. Therefore, you would want the ice to slowly melt and cool the drink for as long as you can.
You would want to have the highest possible volume to surface area ratio in an ice cube. If your ice cube is mostly surface area with less volume, it will melt quickly and water down your drink. If your ice cube has a higher ratio of volume to the surface area, it will stay solid longer and chill your drink longer.

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.
AngleJ = 90° AngleJ' = 90°
AngleK = 65° AngleK' = 65°
AngleL = 25° AngleL' = 25°
Which statement is true about this transformation?
The correct statement is AngleL = 25° AngleL' = 25°.
We have given that,
Triangle JKL is transformed to create triangle J'K'L'.
We have to choose the correct option.
What is the information about the transformed triangle?
The following information should be considered:
In a rigid transformation, the image & pre-image are congruent.
Reflection, translation, and rotation are rigid transformations.
In a non-rigid transformation, the image and pre-image are similar.
Dilation is a non rigid transformation.
In a rigid or nonrigid transformation, the corresponding angles are the same.
If the corresponding sides are the same, then it is a rigid transformation.
If the corresponding sides are proportional, then it is a nonrigid transformation.
It can be a rigid or a nonrigid transformation based on whether the corresponding side lengths have the same measures.
Therefore option 3 is correct.

How many solutions does this linear system have
y =
x+2
6x - 4y = -10
Answer:
This linear system has one solution.
Step-by-step explanation:
First equation: y = x + 2
Second equation: 6x - 4y = -10
Let's change the second equation in slope-intercept form y = mx + b.
Slope-intercept form
y = mx + b
m ... slope
b ... y-intercept
[tex]6x - 4y = -10[/tex]
[tex]6x + 10 = 4y[/tex]
[tex]\frac{6}{4}x + \frac{10}{4} = y[/tex]
[tex]\frac{3}{2}x + \frac{5}{2} = y[/tex]
If two lines have the same slope but different y-intercept, they are parallel - system has no solutions.
If two lines have the same slope and the same y-intercept, they are the same line and are intersecting in infinite many points - system has infinite many solutions.
If two lines have different slopes then they intersect in one point - system has one solution.
We see that lines have different slopes. First line has slope 1 and the other line has slope [tex]\frac{3}{2}[/tex]. So the system has one solution.
You can also check this by solving the system.
Substitute y in second equation with y from first.
6x - 4y = -10
6x - 4(x + 2) = -10
Solve for x.
6x - 4x - 8 = -10
2x = -2
x = -1
y = x + 2
y = -1 + 2
y = 1
The lines intersect in point (-1, 1). <-- one solution

Answer:
80
Step-by-step explanation:
The wording "130% more" suggests that we have the result of adding 130% of the original number to the original number.* This can be expressed as an equation to be solved for the original number.
__
Let x represent the original number. The given relation is ...
184 = x + 130% × x
184 = 2.30x . . . . . . . . . collect terms (130% = 1.3)
80 = x . . . . . . . divide by 2.3
184 is 130% more than 80.
_____
* One needs to be a little careful here. You will often see the wording ...
"<some number> times more".
Usually the intention there is that the result is <some number> times the original amount. That is, percentages are often treated differently from other number expressions in problems like this.
