Answer: to sum up
Step-by-step explanation:
A construction company has 10,992 bags of sand that are to be delivered evenly to 24 job sites. How many bags of sand will each job site receive?
Using division we know that each job site will receive 458 sand bags.
What is division?Multiplication is the opposite of division.
If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.
Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.
So, we know that:
Number of bags: 10992
Bags to be distributed are 24 jobs.
Now, to know the number of bags each job site will receive:
10992/24
458
Therefore, using division we know that each job site will receive 458 sand bags.

We checked the equation of lines are not parallel to each other.
What are parallel lines?
The two lines when located at the same plane and equidistance from each other are called parallel lines. The properties of parallel lines as shown in equation is that both have same slope but different y intercept.
Two parallel lines never intersect.
Does the two lines parallel?equation of line passes through the point (- 3, -3) and (3, 9)
is given by the formula [ y - y₁] = [(y₂- y₁) / (x₂- x₁)] [x - x₁}
[ y- (-3)] = [9 - (-3) / 3- (-3)] [x - (-3)]
(y +3) = [(9+3)/ (3+3)] (x+3)
y+ 3 = 12/ 6 (x+3)
y+3 = 2 (x+3)
y+3 = 2x+6
y = 2x+3 this is the first line.
equation of line passes through (-5, 12) and (1, 0)
[y - 12] = [(0 - 12) / 1 - (-5)] [x - (-5)]
y -12 = -12/ 6 (x+5)
y - 12 = -2 x - 10
y = - 2x + 2
the above is the equation of second line.
the above two equation have same slope but different sign. Hence, the lines are not parallel to each other.

How do you find the number of relations from A to B?
To find the number of relations from a set A to a set B, you need to consider the number of possible mappings or functions between the elements of set A and set B.
Here are the steps to find the number of relations from A to B:Determine the cardinality (size) of set A, denoted as |A|.Determine the cardinality of set B, denoted as |B|.The number of relations from A to B is given by [tex]|A|^{|B|}[/tex]. This is because each element in set A can be mapped to any element in set B.For example, if set A has 3 elements and set B has 4 elements, then the number of relations from A to B is [tex]3^4[/tex] = 81.
Note that not all possible mappings are necessarily valid relations, for example, a function is a type of relationship that has a unique output for each input, so it's a one-to-one relation, whereas a relation can be one-to-one or one-to-many, and also it's a subset of all possible mappings from A to B.

Step-by-step explanation:
Given:
Zoe jogs 3/4 of a mile every 1/5 of an hour.
How many miles does Zoe jog per hour?
[A] 3/20 Miles
[B] 4/15 Miles
[C] 3 3/4 Miles
[D] 6 2/3 Miles
Solve:
Since, Zoe jogs 3/4 of a mile every 1/5 hour. And 5/5 = 1 hour.(Also known as 60 minutes) Which means 1/5 is 12 minutes. In order to find how much Zoe jogs per hour, we have to multiply.
Knowing that;
1/5 = 12 minutes
2/5 = 24 minutes
3/5 = 36 minutes
4/5 = 48 minutes
5/5 = 60 minutes (1 Hour)
Hence, 3/4 Multiply by 5.
3/4 × 5 = 3.75 = 15/4 = 3 3/4
As a result, Zoe jogs 3 3/4 miles per hour.

What is the equation of this line in slope intercept form?
Answer:
y=x-4
Step-by-step explanation:
y=mx+b
Answer: y=x-4
Step-by-step explanation:
The first step is to see what point runs through the y-axis, so you can get your y-intercept. The line runs through (0, -4), so -4 will be your y-intercept.
To calculate the slope, we can use the formula, y2-y1/x2-x1 to find the slope. We have to take two definite points to solve this. an example of two definite points is (1, -3), and (0,-4). So the change in y would be -4-(-3), which is -1, and for the change in x, 0-1 is -1 (Think of (1,-3) as point one, and (0,-4) as point 2). SO -1/-1 is 1, making the slope 1, making the equation y=x-4
What is the value of a base?

3/5 of the marbles are blue. If there are only yellow and blue marbles, what is the ratio of blue marbles to yellow marbles?
Answer: 3:2
Step-by-step explanation:
If 3/5 of the marbles are blue, then the last 2/5 will be yellow.
Answer:
Hey there! So as you know, 3 out of 5 marbles are blue, which can be written as 3/5. To find the ratio of blue to yellow marbles, we need to find the number of yellow marbles.
We know that 5 marbles are blue and yellow combined, and 3 of them are blue, so that leaves 5-3 = 2 yellow marbles.
So the ratio of blue marbles to yellow marbles is 3:2, or 3/2. It means that for every 3 blue marbles, there are 2 yellow marbles.

600 joules of work is used to lift a box from the ground to a height of six meters. how much work would have been done if a lever would have been used with an effort arm of 12 meters and a load arm of 6 meters?
If a lever was used with an effort arm of 12 meters and a load arm of 6 meters, the work that would have been done would've been (A) 50 J.
What does a lever do?Using a lever makes work simpler and quicker since it only takes a bit of effort to move a heavy load.
The efficiency of the machine goes up when the output force is bigger than the input force - the formula for this is Output Force divided by Input Force.
Eff = ( output force/input force ) x 100 %
The amount of force you get is determined by this equation.
F ( out ) = load x distance moved by the load
The force you put in is calculated using this equation.
F ( input ) = effort x distance moved by the effort
If we had used a lever with an effort arm of 12 meters and a load arm of 6 meters, the work that would have been done could be calculated.
work = ( 600 x 6 ) / ( 12 x 6 )
work = 50 J
