After traveling every 84 km, a motorbike needs to fill petrol and after 120 km it needs to change Mobil. If these works are done together, after traveling what distance will both the works repeat again?
Answer:
Both works will be repeated at 840km
Step-by-step explanation:
Given
Fills Petrol = Every 84km
Change Mobil = Every 120km
Required
Determine the distance where both works are done at the same time
This solution to this question is to solve for the LCM of 84 and 120
Start by factoring 84
[tex]84 = 2 * 2 * 3 * 7[/tex]
Then, 120
[tex]120 = 2 * 2 * 2 * 3 * 5[/tex]
Then the LCM is as follows;
[tex]LCM = 2 * 2 * 2 * 3 * 5 * 7[/tex]
[tex]LCM = 840[/tex]
Hence, both works will be repeated at 840km

How many solutions are there to the equation below?
12x + 32 = 12x - 7
O A. O
B. 1
O C. Infinitely many
Answer:
A
Step-by-step explanation:
12x + 32 = 12x - 7
12x - 12x + 32 = 12x - 12x - 7
32 = -7
This is a false statement so the answer is A) 0.
Additionally, you can see that we have the quantity 12x on both sides but on one side, it's being added by 32 and on the other, it's being subtracted by 7. How can a quantity added by 32 be equal to the same quantity subtracted by 7? It is impossible for a real number to do so, therefore, the answer is 0.
Answer:
Hey there!
Original Equation: 12x+32=12x-7
Subtract 12x: 32=-7
32 does not equal -7, so there is no solution.

Answer:
Domain: [tex](-\infty,\infty)[/tex]
Range: [tex][-5,\infty)[/tex]
C
Step-by-step explanation:
Please refer to the graph.
Recall that the domain is the span of x-values covered by the graph, while the range is the span of y-values covered by the graph.
So we have the equation.
[tex]y=(x+3)^2-5[/tex]
This is a quadratic.
The domain of a quadratic is all real numbers. If you look at the graph, we can also see that the x-values will go on infinitely in both direction.
In interval notation, this is:
[tex](-\infty,\infty)[/tex]
For the range, note that the lowest the parabola goes is y=-5.
Therefore, our range is all values greater than or equal to -5.
In interval notation, this is:
[tex][-5,\infty)[/tex]
Note that we use brackets for the -5 because it is included in our range.
So, our answer is C
Answer:
Step-by-step explanation:
the domain and range of y = (x+3)^2 - 5
Doman: (-∞,∞). {x|x∈R}
Range:{-5,∞),{y|y≥-5}

There are three consecutive integers such that twice the sum of the smallest and the largest is eight more than twice the largest. Find the smallest integer in the sequence.
Answer: 4
Step-by-step explanation:
Let the consecutive integers be x, x+1 and x+2.
There are three consecutive integers such that twice the sum of the smallest and the largest is eight more than twice the largest. This means that:
2(x + x+2) = 2(x+2) + 8
2(2x + 2) = 2x + 4 + 8
4x + 4 = 2x + 12
Collect like terms
4x - 2x = 12 - 4
2x = 8
x = 8/2
x = 4
The smallest integer in the sequence is 4
The pizza has an area of 78.5 in². What is the minimum width of a placemat that can be placed underneath it so that the pizza does not touch the table? Use 3.14 for pi. someone pls help me
Answer:
The minimum width of the placemat is 10 inches.
Step-by-step explanation:
Let suppose that placemat has a square form, whose width must be at least equal to the diameter of the pizza, so that pizza does not touch the table. Hence, the following relationship is obtained:
[tex]w = D[/tex]
Where:
[tex]w[/tex] - Width of the placemat, measured in inches.
[tex]D[/tex] - Diameter of pizza, measured in inches.
The area of the pizza, measured in square inches, is determined by this formula:
[tex]A = \frac{\pi}{4} \cdot D^{2}[/tex]
The diameter is cleared afterwards:
[tex]D = \sqrt{\frac{4\cdot A}{\pi} }[/tex]
If [tex]A = 78.5\,in^{2}[/tex] and [tex]\pi = 3.14[/tex], then:
[tex]D = \sqrt{\frac{4\cdot (78.5\,in^{2})}{3.14} }[/tex]
[tex]D = 10\,in[/tex]
The minimum width of the placemat is 10 inches.
The minimum width of a placemat that can be placed underneath the pizza so that the pizza wouldn't touch the table is; 10 inches
We are told that the pizza has an area of 78.5 in². Thus;
A = 78.5 in²
Now, the pizza is circular in shape and the minimum width of a placemat that can be placed underneath the pizza so that the pizza wouldn't touch the table will be the diameter of the pizza
Thus, area of a circle with diameter d is;
A = πd²/4
Plugging in the relevant values, we have;
78.5 = 3.14d²/4
d² = 78.5 × 4/3.14
d² = 100
d = √100
d = 10 inches.

A Women making $29 an hour gets a 15% raise. How much money will she make after 4 hours of working with the increased hourly pay?
Answer:
$133.40
Step-by-step explanation:
First you have to find 15% of 29 which is 4.35. The way I figured this out was 10% of 29 is 2.9 and 5% of 29 is 1.45 and 2.9 + 1.45 = 4.35.
Then you want to add 4.35 to 29 which equals 33.35, her new hourly pay. Multiply 33.35 by the 4 hours she is working and you end up with $133.40.

A survey reported that 40% of people save loose change to pay bills. The margin of error was given as 3.1 percentage points. Which confidence interval corresponds to the given information
Answer:
0.369≤[tex]\mu[/tex]≤0.431Step-by-step explanation:
The confidence interval boundaries is represented mathematically as shown below;
CI = p±E where;
p is the percentage of people surveyed
E is the margin of error
Given parameters
p = 40% = 0.4
E = 3.1% = 0.031
Required
Confidence interval corresponds to the given information.
Substituting the given parameters into the given formula:
CI = p±E
CI = 0.4±0.031
CI = (0.4-0.031, 0.4+0.031)
CI = (0.369, 0.431)
Hence the confidence interval that corresponds with the information is 0.369≤[tex]\mu[/tex]≤0.431.
Water flows through a pipe at a rate of 7 liters every 9.5 hours. Express this rate of flow in pints per week. Round your answer to the nearest whole number

How does -2x + x equal -x ?
Answer:
See below.
Step-by-step explanation:
[tex]-2x+x=-x[/tex]
because we combine like terms. You will essentially ignore the x and just do -2 + 1, which is -1. So, the answer would be -1x which is simply just -x.
To see why we can combine like terms, use the distributive property. So we have:
[tex]-2x+x[/tex]
This is the same thing as saying:
[tex]=(-2)x+(1)x[/tex]
Factor out the x:
[tex]=x(-2+1)[/tex]
Add:
[tex]=x(-1)[/tex]
And simplify:
[tex]=-1x\\=-x[/tex]
Answer:
Step-by-step explanation:
-2x + x could also be written as x - 2x, which is x(1 - 2), or -x. Here we can rearrange the terms as we wish (commutative property).
A coach for a little league baseball team is ordering trophies for the team. Players on the team are allowed to choose between 2 types of trophies. The gold baseball trophies cost $5.99 each and the uniform baseball trophies cost $6.49 each. The team orders g gold baseball trophies and u uniform baseball trophies. Write an expression that could represent the total cost of all of the trophies.
Answer:
y= 5.99(g) + 6.49(u)
Step-by-step explanation:
1) First you determine the variable in the equation $5.99, $6.49, g, and u.
2) Then analyze the equation and identify that each gold baseball trophy (g) is worth $5.99, and each uniform baseball trophy (u) is worth $6.49 each.
3) Since you are finding the total you insert a plus sign.
The expression that could represent the total cost of all of the trophies will be C = 5.99g + 6.49u
Cost of gold baseball trophies = $5.99
Cost of uniform baseball trophies = $6.49
Number of gold baseball trophies ordered = g
Number of uniform baseball trophies ordered = u
Therefore, the total cost will be:
= (5.99 × g) + (6.49 × u)
C = 5.99g + 6.49u
Therefore, the expression that could represent the total cost of all of the trophies is C = 5.99g + 6.49u

If A and B are independent events with P( A) = 0.60 and P( A| B) = 0.60, then P( B) is: a. 0.60 b. cannot be determined with the information given c. 0.36 d. 1.2
Answer:
B. cannot be determinedStep-by-step explanation:
For two events A and B to be independent, it means they can occur at the same time i.e the occurrence of one does not affect the other occurring. It is represented as P(A∩B) = P(A)P(B)
Given P( A) = 0.60 and P( A| B) = 0.60, to find P(B), we will use the formula for the conditional probability P( A| B) = P(A∩B) /P(B)
P( A| B) = P(A)P(B) /P(B)
P( A| B) = P(A)
Since P( A| B) = 0.60, therefore P(A) is also equal to 0.60 and P(B) cannot be determined since they cancelled out already
