Answer:
6 × 5
Step-by-step explanation:
If you want to reduce the fraction 12/30, you want to find the greatest common factor of 12 and 30. We can find that by looking at the prime factorization of each number.
12 = 2·2·3
30 = 2·3·5
The greatest common factor is 2·3 = 6. This means ...
[tex]\dfrac{12}{30}=\dfrac{12}{6\times5}[/tex]
The product of interest is 6 × 5.
_____
Additional comment
Any of the factor pairs of 30 could be used. Only the one shown is useful for reducing the fraction to lowest terms.
30 = 1×30 = 2×15 = 3×10 = 5×6

The Johnson and Smith families want to determine the difference in utility prices between March, when it's warmer, and January. Matrix J is for January. The rows represent electric, natural gas, and cable/satellite. The columns are the Johnson and Smith Family. Matrix M is for March. Write a matrix to show the difference in prices from January to March (J-M)? What do you think it means when you get a negative number in your resulting matrix?
Answer:
[tex]\left[\begin{array}{ccc}-8&0\\12&-23\\4&7\end{array}\right][/tex] negative represents a decrease
Step-by-step explanation:
looking at the same place on both matrix, find the difference between the numbers
97 to 89- goes down 8-- so -8
86 to 86 is no change 0
185 to 197 is an increase of 12
210 to 187 is a decrease of 23
39 to 43 is an increase of 4
67 to 73 is in increase of 7
the negative represents a decrease
The answer matrix is [tex]\left[\begin{array}{ccc}8&0\\-12&23\\-4&-6\end{array}\right][/tex] and the negative sign is representing the increase in the price of utility from January to March.
What is matrix?A matrix is a rectangular arrangement of a collection of numbers into a fixed number of rows and columns.
Give that, two matrices J and M showing the difference in utility prices between March and January. The rows represent electric, natural gas, and cable/satellite. The columns are the Johnson and Smith Family.
J-M = [tex]\left[\begin{array}{ccc}8&0\\-12&23\\-4&-6\end{array}\right][/tex]
In the matrix, the negative sign is representing the increase in prices because in January it was cheaper therefore less than the price in March and subtracting a greater number with minus sign to a smaller number will give a negative result.
That mean, some utilities were cheaper in January than in March.
Hence, The answer matrix is [tex]\left[\begin{array}{ccc}8&0\\-12&23\\-4&-6\end{array}\right][/tex] and the negative sign is representing the increase in the price of utility from January to March.

A bag contains 7 red marbles, 8 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the probability, to the nearest 100oth, that all three
marbles drawn will be blue?
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

Step-by-step explanation:
Appling the principle of supplementary angle in Geomentry.
Supplementary angle: These are angles that sum up to 180°
From the diagram above, x and 134° are supplementry because they sum up to 180°.
Therefore,
134+x = 180 (Supplementary angle)
Solve for x
x = 180-134

A cyclist travels 4.9 km in 30 minutes.
What is his average speed in km/h?
Answer:
9.8 km/h
Step-by-step explanation:
Since there are 60 minutes in an hour, we can find his speed in km/h by multiplying 4.9 by 2.
4.9(2)
= 9.8
This means that he will travel 9.8 km in 60 minutes (1 hour).
So, his average speed is 9.8 km/h
Select ALL the sets of three side lengths that will make a triangle.
3, 4, 8
7, 6, 12
5, 11, 13
4, 6, 12
4, 6, 10
Answer:
7 + 6
5 + 11
Step-by-step explanation:
the lengths of the two shorter sides of a triangle must add up to more than the length of the third side.
3 + 4 = 7 ≤ 8 no
7 + 6 = 13 > 12 yes
5 + 11 = 16 > 13 yes
4 + 6 = 10 ≤ 12 no
4 + 6 = 10 ≤ 10 no
===================================================
Explanation:
We'll use the triangle inequality theorem. Recall that this theorem says that a triangle is only possible if and only if adding any two sides leads to a sum larger than the third side.
Let's say we had a triangle with sides a,b,c. Such a triangle is only possible if all three conditions hold true
a+b > cb+c > aa+c > b----------------
Let's go through each answer choice to see if those conditions hold up.
Choice A. We have a = 3, b = 4, c = 8. Note that a+b = 3+4 = 7 which is not greater than c = 8. Therefore a+b > c is false, and we cannot make a triangle here. We don't need to check the other inequalities. I recommend you trying it out by cutting out slips of paper of these lengths. You'll find a triangle cannot be constructed. We can rule out choice A.Choice B. We have a = 7, b = 6 and c = 12. We can see that a+b = 7+6 = 13 which is larger than c = 12. So far, so good. Then note that b+c = 6+12 = 18 which is larger than a = 7. Finally, a+c = 7+12 = 19 which is larger than b = 6. Picking any two sides, adding them up, leads to a sum larger than the third side. A triangle is possible in this case. Choice B is one of the answers.Choice C. This time a = 5, b = 11, c = 13. You should find that a triangle is possible following the same steps as done in choice B above. Adding any two sides leads to a sum larger than the third side. Choice C is one of the answers. Choice D. Now we have a = 4, b = 6, c = 12. Then note a+b = 4+6 = 10 which is too small compared to c = 12. Meaning a+b > c is false. A triangle isn't possible. Cross choice D off the list.Choice E. In this case, a = 4, b = 6 and c = 10. Adding the first two values gets us a+b = 4+6 = 10 which is not larger than c = 10. If you used slips of paper, you'd find that a straight line is formed rather than a triangle. Cross choice E off the list.To wrap things up, only choice B and choice C are possible triangles because adding any two sides leads to a sum larger than the third side.
